Description

Technical Field

[0001] The invention relates to the technical field of piggyback transportation, and in particular to a translational piggyback transportation system. Background Art

[0002] The piggyback transport system includes piggyback vehicles and station equipment. The piggyback vehicle refers to a road truck or semi-trailer, which is loaded with goods and then driven onto the piggyback vehicle by itself at the departure railway station, and completes long-distance transportation by rail. After arriving at the destination railway station, the road vehicle can drive off the piggyback vehicle by itself and drive to the final destination. It is a convenient transportation method.

[0003] The body of a sled can generally include a main body and a detachable support. When loading and unloading, the support can be first translated and separated from the main body to facilitate the on and off of highway vehicles. After loading and unloading, the support can be installed on the main body again. If the driving mechanism used to drive the support to translate and separate from the main body is all located on the body, the overall structure of the body will be more complicated, and the weight and cost of the body can also be increased. Therefore, how to simplify the structure of the sled, achieve lightweight, and realize the separation, coordination and translation operation between the support and the main body in the loading and unloading station is a technical problem to be solved by those skilled in the art. Summary of the invention

[0004] The purpose of the present invention is to provide a translational piggyback transport system, which can simplify the structure of the piggyback vehicle, achieve lightweight, and realize the separation, matching and translation operations between the support part and the main body part at the loading and unloading station.

[0005] In order to solve the above technical problems, the present invention provides a translational type piggyback transport system, which includes a piggyback vehicle and station equipment, the piggyback vehicle includes a main body and a supporting part, the main body includes a chassis and a bogie arranged under the chassis, and the two ends of the supporting part are respectively connected to one of the chassis; the station equipment includes a loading and unloading station, a translation device, two groups of chassis lifting parts and two groups of supporting part lifting parts; the loading and unloading station is arranged on a side platform outside the track; the two groups of chassis lifting parts can respectively lift the chassis at both ends of the supporting part until the center plate of the bogie is not subjected to force; the two groups of supporting part lifting parts can respectively lift the two ends of the supporting part to separate the two ends of the supporting part from the chassis; when the supporting part is in a detached state from the chassis, the translation device can move the supporting part between the track and the loading and unloading station.

[0006] When the saddlebag truck reaches the preset position of the loading and unloading station, a group of chassis lifting parts are respectively provided under the two chassis in front and rear of the supporting part, and a group of supporting part lifting parts are respectively provided under the front and rear ends of the supporting part. The two groups of chassis lifting parts are first used to lift the chassis and the supporting part together from both ends at the same time until the two groups of bogie center plates are no longer under force. The chassis lifting parts keep their function unchanged, and then the two groups of supporting part lifting parts continue to lift the supporting part upward from both ends to separate it from the chassis. Then the supporting part lifting parts keep their function unchanged. Finally, the translation device acts on the supporting part to translate it outside the track to the loading and unloading station, and then the loading and unloading operations can be carried out.

[0007] The lifting part of the chassis, the lifting part of the supporting part and the translation device are all arranged at the loading and unloading station, so that the main body of the back-carrying vehicle does not need to be provided with a corresponding lifting part and translation device. In this way, the back-carrying vehicle can realize the lifting and translation operations at the loading and unloading station, simplify the overall structure of the back-carrying vehicle, thereby reducing its own weight and improving economic efficiency. In addition, the station equipment can cooperate with different back-carrying vehicles passing through the track to load and unload goods, improve its applicability and further reduce costs.

[0124] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0125] In the present application, the length direction of the piggyback vehicle is the longitudinal direction, which also refers to the front-to-back direction; in the running plane of the railway vehicle, the direction perpendicular to the longitudinal direction is the transverse direction, which also refers to the left-right direction. In the transverse direction, the position relatively close to the transverse center of the railway track is the inside, and the position relatively far from the transverse center of the railway track is the outside; the direction perpendicular to the above-mentioned running plane is the vertical direction, among which the direction relatively far from the ground is the top, and the direction relatively close to the ground is the bottom.

[0126] In the present application, “first”, “second”, “third” and similar reference words are used only to facilitate the distinction of description and should not be understood as indicating or implying relative importance or representing an order relationship.

[0127] Please refer to Figure 1-4 , Figure 1 It is a structural schematic diagram of a translational piggyback transport system provided by an embodiment of the present invention; Figure 2 It is a schematic diagram of the structure when the support part is translated to the loading and unloading station; Figure 3 It is a structural diagram of the station equipment; Figure 4 yes Figure 3 Schematic diagram of the local structure;

[0128] The embodiment of the present invention provides a translational piggyback transport system, such as Figure 1 and Figure 2 As shown, the translational piggyback transport system includes a piggyback vehicle and station equipment, wherein the piggyback vehicle includes a main body 1 and a support 4, the main body 1 includes a chassis and a bogie disposed below the chassis, and both ends of the support 4 are respectively connected to a chassis; Figure 3 and Figure 4 As shown, the station equipment includes a loading and unloading station, a translation device, two groups of chassis lifting parts and two groups of supporting part lifting parts, wherein the loading and unloading station is arranged on the side platform outside the track 100, and the two groups of chassis lifting parts can respectively lift the chassis at both ends of the supporting part 4, so that the two groups of chassis drive the supporting part 4 to move upward until the center plate of the bogie is no longer under force; the two groups of supporting part lifting parts can respectively lift the two ends of the supporting part 4 to separate the supporting part 4 from the chassis.

[0129] When the support 4 is in a disengaged state from the base frame, the translation device can move the support 4 between the track 100 and the loading and unloading station, that is, the translation device can move the support 4 outward to the loading and unloading station for loading and unloading operations. When the loading and unloading is completed, the translation device can also move the support 4 inward to the track 100 corresponding to the base frame, and then the support 4 is lowered and cooperated with the base frame through the action of the support lifting part.

[0130] In detail, Figure 1 As shown, when the piggyback vehicle reaches the preset position of the loading and unloading station, a group of chassis lifting parts are respectively provided under the two chassis in front and behind the supporting part 4, and a group of supporting part lifting parts are respectively provided under the front and rear ends of the supporting part 4. The two groups of chassis lifting parts are first used to lift the chassis and the supporting part 4 together from both ends at the same time until the two groups of bogie center plates are no longer under stress. The chassis lifting parts maintain their function unchanged, and then the two groups of supporting part lifting parts continue to lift the supporting part 4 upward from both ends to separate it from the chassis. Then the supporting part lifting parts maintain their function unchanged, and finally the translation device acts on the supporting part 4 to translate it to the outside of the track 100 to the loading and unloading station (such as Figure 2 After that, loading and unloading operations can be carried out.

[0131] In this embodiment, the underframe lifting part, the supporting part lifting part and the translation device are all arranged at the loading and unloading station, so that the main body of the pack-back vehicle does not need to be provided with a corresponding lifting part and translation device 600. In this way, the pack-back vehicle can simplify the overall structure of the pack-back vehicle while realizing the lifting and translation operations at the loading and unloading station, thereby reducing its own weight and improving economic efficiency. In addition, the station equipment can cooperate with different pack-back vehicles passing through the track 100 to load and unload goods, improve its applicability, and further reduce costs.

[0132] In the above embodiment, the station equipment is provided with a translation path perpendicular to the track 100, and the support part 4 can move to the loading and unloading station along the translation path after being separated from the base frame, and the translation device 600 includes a driving assembly and a translation part 600, and the driving assembly can drive the translation part 600 to drive the support part 4 to move along the translation path. In detail, after being lifted by the base frame lifting part and the support part lifting part, the support part 4 is separated from the base frame, and then the driving assembly drives the translation part 600 to move to the bottom of the support part 4 along the translation path, and the support part lifting part acts to make the support part 4 descend and fall onto the translation part 600, and then the driving assembly acts on the translation part 600 to drive the support part 4 to move along the translation path to the loading and unloading station outside the track 100, and after the loading and unloading is completed, the translation part 600 can drive the support part 4 to move in the opposite direction along the translation path to the track 100 and correspond to the base frame.

[0133] Specifically, the translation path can be a slide rail or a slide groove, etc., to limit the movement of the translation part 600, to ensure that the translation part 600 can correspond to the base frame when driving the support part 4 to move inward along the translation path to the track 100, and can move to the loading and unloading station when moving outward. No specific restrictions are made here.

[0134] Alternatively, in the present embodiment, the support part 4 can also be arranged to be moved to the side platform outside the track 100 by means of a mobile trolley, and the overall structure can be simplified by setting the driving assembly, the translation part 600 and the translation path, and the stability of the translation can be ensured, thereby avoiding the deflection of the support part 4 during the translation process, and ensuring that it can move along the translation path.

[0135] Furthermore, the driving assembly includes an outer driving member 300 and an inner driving member 400, wherein the outer driving member 300 is arranged at the loading and unloading station of the side platform outside the track 100, and the inner driving member 400 is arranged inside the track 100. The top ends of the outer driving member 300 and the inner driving member 400 are respectively provided with driving wheels 500, and the axis of each driving wheel 500 is parallel to the track 100 (that is, perpendicular to the translation path), and the top end of each driving wheel 500 is abutted against the lower end surface of the translation part 600, and can drive the translation part 600 to move along the translation path. That is to say, driving wheels 500 are respectively provided outside the track 100 and inside the track 100, which are used to drive the translation part 600 to move along the translation path. Alternatively, in this embodiment, the driving component can also include a push-pull part that can push and pull the supporting part 4 to move along the translation path. The push-pull part is arranged on the side platform outside the track 100. Each driving wheel 500 is only an ordinary roller. The push-pull part can push and pull the supporting part 4 to make it roll along the roller. The solution of setting the external driving member 300 and the internal driving member 400 to have driving wheels 500 can simplify the overall structure.

[0136] In the above embodiment, the lower end surface of the translation part 600 is provided with a first limiter part, and the driving wheel 500 is provided with a second limiter part. The first limiter part and the second limiter part are adapted to each other and can make the translation part 600 move along the translation path, thereby ensuring the stability and accuracy of the translation of the support part 4. Specifically, there is no restriction on the structure of the first limiter part and the second limiter part. For example, the first limiter part can be set as a limiter groove, and the second limiter part can be set as a limiter protrusion, or the first limiter part can be set as a limiter protrusion, and the second limiter part can be set as a limiter groove. In addition, the cross-section of the limiter groove can be a U-shaped structure or a V-shaped structure, which is not specifically limited here.

[0137] In the above embodiment, the loading and unloading station is further provided with a side platform lifting unit 200 for lifting the supporting unit 4. The side platform lifting unit 200 is used to lift and support the supporting unit 4 at the loading and unloading station, that is, after the supporting unit 4 is translated to the outside of the track 100 to the loading and unloading station by the translation device, the side platform lifting unit 200 will lift the supporting unit 4 upward, and then move the translation unit 600 of the translation device along the translation path to the outside of the loading and unloading station, and then the height of the supporting unit 4 is lowered by the side platform lifting unit 200 until the height difference between the two ends of the supporting unit 4 and the ground at the two ends of the loading and unloading station is within a preset range, and then the loading and unloading operation can be carried out.

[0138] Specifically, after the translation unit 600 moves the support unit 4 to the loading and unloading station, it can be moved outside the loading and unloading station to avoid affecting the descending height of the support unit 4. The ground of the side platforms at both ends of the loading and unloading station can be provided with a slope transition device, or a pad can be used to reduce the height difference between the ground and the end of the support unit 4, or a groove can be provided in the loading and unloading station, and the side platform lifting unit 200 can be provided in the groove, so that the support unit 4 can be descended to the height difference between its end and the ground of the side platform within a preset range. The specific setting can be made according to the actual situation to facilitate the smooth loading and unloading of goods.

[0139] In the above embodiment, the platforms on both sides outside the track 100 are provided with external driving parts 300 and side platform lifting parts 200, that is, the side platforms on both sides outside the track 100 are respectively provided with loading and unloading stations, and both can be used for loading and unloading. When the translation part 600 translates a supporting part 4 to the loading and unloading station of a side platform, the translation part 600 is moved to the assembly station of the side platform on the other side of the track 100 through the action of the side platform lifting part 200, and the other supporting part 4 that has been loaded and unloaded is translated inward to correspond to the chassis. In this way, the loading and unloading efficiency of the piggyback vehicle when passing through the loading and unloading station can be effectively improved.

[0140] Furthermore, for a loading and unloading station with multiple tracks 100 and multiple side platforms arranged side by side, each side platform is provided with a loading and unloading station and shares the same translation path and translation device. At this time, the translation part 600 can carry out the transport work of the support part 4 between multiple loading and unloading stations and tracks 100, thereby simplifying the overall structure.

[0141] Please refer to Figure 5 , Figure 5 It is a structural schematic diagram of a specific implementation method of the main body of a saddlebag.

[0142] like Figure 5 As shown, both longitudinal ends of the support portion 4 are provided with connecting structures, wherein the connecting structure includes an upper hook 421 and a lower circular shaft 412c extending in the transverse direction, and the base frame is provided with an end connecting mechanism 22, the end connecting mechanism 22 includes an end connecting hook 221 and an end longitudinal support 222, the end connecting hook 221 forms a hook mouth arranged upward, in the assembled state, the lower circular shaft 412c can be hung on the hook mouth of the end connecting hook 221, and the upper hook 421 can be clamped on the end longitudinal support 222.

[0143] By adopting this structure, there can be two connection points between the longitudinal ends of the support part 4 and the main body 1, formed by the upper hook 421 and the end longitudinal support piece 222, and the lower circular shaft 412c and the end connecting hook 221, so that the connection between the support part 4 and the main body 1 can be more reliable; and when separating, the base frame is lifted by the base frame lifting part, and the base frame and the support part 4 can also rotate relative to each other with the central axis of the lower circular shaft 412c as the rotation center line, forcing the connection between the upper hook 421 and the end longitudinal connecting piece 222 to loosen, thereby facilitating the separation of the support part 4 and the base frame.

[0144] The following embodiments of the present invention will respectively describe the structures of different components of the body of the sled vehicle.

[0145] Support 4

[0146] Please refer to Figure 6-15 , Figure 6 It is a schematic diagram of the support structure; Figure 7 for Figure 6 Exploded view of; Figure 8 for Figure 7 A partial enlarged view of the hook in the upper middle part; Fig. 9 for Figure 8 A front view of Fig.10 for Figure 7 A partial enlarged view of the middle A; Fig.11 for Figure 7 A partial enlarged view of point B in the middle; Fig.12 is a structural schematic diagram of the end wall; Fig.13 for Fig.12 Schematic diagram of the structure from another perspective; Fig.14 This is the connection structure diagram of the middle wall and the inclined wall; Fig.15 for Fig.14 Schematic diagram of the structure from another perspective.

[0147] like Figure 6 As shown, combined with Figure 8 , Fig. 9 The clamping surface between the upper hook 421 and the end longitudinal support member 222 may include a top surface segment 421a and two side surface segments 421b to form a U-shaped clamping surface with an opening facing downward; of the two side surface segments 421b, the first one may be a vertical surface, and the second one may be an inclined surface inclined from top to bottom in a direction away from the first one, or both side surface segments 421b may be inclined surfaces inclined from top to bottom in a direction away from each other.

[0148] In this way, the clamping surface can form a conical clamping opening that gradually decreases from bottom to top. This form of conical clamping opening can facilitate the clamping of the upper hook 421 and the end longitudinal support 222, and the clamping effect will increase with the proximity of the support part 4 and the main body 1, forming a connection feature that becomes tighter as it falls; moreover, since the lower opening of the conical clamping opening is larger, once the connection between the upper hook 421 and the end longitudinal support 222 becomes loose, the two can be separated relatively easily.

[0149] It should be noted that the above-mentioned conical clamping opening is only a preferred solution of the embodiment of the present invention, and cannot be used as a limitation on the implementation scope of the body of the saddlebag provided by the present invention. In specific implementation, the two side sections 421b can also be set as vertical surfaces, which can also meet the technical effect of clamping installation with the main body.

[0150] During the installation and separation of the support part 4 and the main body, there will be friction in the form of sliding friction, static friction, etc. between the clamping surface of the upper hook 421 and the main body, which may cause wear to the upper hook 421. For this reason, a support wear plate 421c can be provided on the two side segments 421b to replace the direct wear of the upper hook 421 with the wear of the support wear plate 421c, which has a positive effect on improving the service life of the support part 4.

[0151] Please continue to refer to Fig. 9 , each support wear plate 421c can be connected to the side section 421b by a connection piece in the form of a screw, etc., and during the installation, separation and use of the support 4, the direction of the friction force on each support wear plate 421c is perpendicular to the axial direction of the above-mentioned connection piece, which will cause each connection piece to bear unnecessary shear force. Under long-term use conditions, this shear force will seriously affect the connection reliability of the support wear plate 421c. In fact, even if the support wear plate 421c is fixed by welding, the weld will also be subject to the above-mentioned shear force.

[0152] To address this, in an embodiment of the present invention, a shear stop structure may be provided between the support wear plate 421c and the side segment 421b to offset the friction force borne by the support wear plate 421c through the shear stop structure. In this way, each connecting member (or weld) can basically be in a state of being free of stress in the vertical direction, and the reliability of the connection can be higher.

[0153] Specifically, the anti-shear stop structure can be provided on the support wear plate 421c, as shown in the attached Fig. 9 The support wear plate 421c located on the left side in the middle can be roughly L-shaped, and the transverse portion of the L-shaped can be against the side segment 421b, so that the friction force acting on the support wear plate 421c can act on the upper hook 421 through the transverse portion, thereby eliminating the above-mentioned shear force; alternatively, the anti-shear stop structure can also be set on the side segment 421b, as shown in the attached Fig. 9 The side section 421b located on the right side may be provided with a notch, and the support wear plate 421c may be installed in the notch and abut against the top wall of the notch, thereby offsetting the friction force borne by the support wear plate 421c through the force with the top wall, so as to finally eliminate the shear force.

[0154] Combination Figure 7 The supporting portion 4 may include a bottom wall 41 and two side walls 42 connected to the bottom wall 41 , and upper hooks 421 may be provided at both longitudinal ends of the side walls 42 .

[0155] Moreover, the side wall 42 can also be provided with a guide limit member 422, which can be specifically arranged on the upper hook 421, and its shape can be plate-like, block-like, columnar, etc. It is mainly used to cooperate with the limit guide member of the main body 1 (the specific structure can be found in the description of the main body 1 in the following text) to guide the installation of the support part 4 and to form a lateral limit of the support part 4.

[0156] For example, the limiting guide member of the main body 1 can be provided with a limiting guide groove. From bottom to top, the limiting guide groove can include an equal-width groove section and a variable-width groove section. The width here refers to the lateral dimension. The width of the equal-width groove section can be substantially the same as that of the guide limiting member 422, while the width of the variable-width groove section can gradually increase from bottom to top. In this way, through the cooperation between the guide limiting member 422 and the variable-width groove section, the installation of the support part 4 can be guided to ensure the accuracy of the installation position of the support part 4. When the guide limiting member 422 is inserted into the equal-width groove section, the cooperation between the guide limiting member 422 and the equal-width groove section can also limit the support part 4 laterally.

[0157] The outer side surface of the side wall 42 may also be provided with a reinforcement structure 423 to increase the strength of the side wall 42. The reinforcement structure 423 may specifically be a reinforcement component in the form of a reinforcement rib, a reinforcement plate, etc. Alternatively, when the body of the sled provided by the present invention is used to transport containers, the reinforcement structure 423 may be an installation position for a container lock. In this way, a separately arranged reinforcement structure 423 may be omitted, which is conducive to simplifying the structure of the side wall 42.

[0158] Combination Fig.10 , Fig.11 In an exemplary solution, to set the installation position of the container lock, the upper cover plate of the side wall 42 can be modified first. A notch groove 423e can be set on the outer side of the upper cover plate. Corresponding to the position of the notch groove 423e, an inner plate 423d and an outer plate 423c can be set on the inner and outer sides respectively, as well as a neutral plate 423a and an end plate 423b connecting the inner plate 423d and the outer plate 423c. This type of installation position has a significant strengthening effect on the side wall 42, and can replace traditional strengthening components in the form of reinforcement ribs, reinforcement plates, etc.

[0159] It can be understood that the above description of the specific structure of the container lock installation position is only an exemplary description of the installation position of a specific container lock, which cannot represent the installation positions of all forms of container locks. In specific implementation, if the structure of the required container lock changes, the structure of the above installation position can be adaptively adjusted. This can be referred to the prior art and will not be described in detail here.

[0160] The bottom wall 41 may include a middle wall 411 and end walls 412 located on both sides of the middle wall 411 in the longitudinal direction. Fig.12 , Fig.13 As shown, the end wall 412 may include a main body portion 412a and a connecting portion 412b, wherein the connecting portion 412b may be used to connect the main body portion 412a and the side wall 42; in the process of loading and unloading, since the road vehicle has to drive up and down continuously, the wheels of the road vehicle have to frequently roll over the main body portion 412a. In order to improve the strength and service life of the main body portion 412a, the main body portion 412a may adopt a box-type structure, which can ensure strength on the one hand and reduce weight on the other hand; the lower circular shaft 412c may be installed at one end of the main body portion 412a away from the middle wall 411.

[0161] The connecting portion 412b may be a C-shaped plate including a vertical plate portion 412b-1 and a side plate portion 412b-2. In this way, the strength of the connecting portion 412b itself can be relatively high, and the connection reliability between the main body portion 412a and the side wall 42 can be ensured to a large extent. In addition, the side plate portion 412b-2 may also include an inclined plate section 412b-3 that gradually inclines upward from the inside to the outside, Fig.12This type of inclined plate segment 412b-3 can guide the tire of the road vehicle to ensure that the tire of the road vehicle rolls on the main body portion 412a as much as possible.

[0162] Pressure plates 412d may also be provided on both lateral sides of the main body portion 412a. When the support portion 4 falls and is installed on the main body portion, the pressure plates 412d may serve as driving members to drive the brake pipe protection device (not shown in the figure) to rotate back to its original position.

[0163] For example Fig.14 , Fig.15 As shown, the middle wall 411 may include two longitudinal beams 411a spaced apart in the transverse direction, and the two longitudinal beams 411a may be connected by a plurality of transverse beams 411b spaced apart in the longitudinal direction. Since the weight of a road vehicle is mainly transmitted through the wheels on both sides in the transverse direction, the middle wall 411 with the above structure can bear the gravity transmitted by the wheels on both sides in the transverse direction through the two longitudinal beams 411a spaced apart in the transverse direction, and the part in the transverse middle area that does not need to be in direct contact with the wheels can adopt a hollow structure composed of a plurality of spaced transverse beams 411b, which has a positive effect on reducing the weight of the middle wall 411.

[0164] Of course, the middle wall 411 may also be an integrated wall, which does not affect its bearing function for road vehicles.

[0165] Each longitudinal beam 411a may include a flat beam section 411a-1 and a lattice beam section 411a-2. The flat beam section 411a-1 may include a flat plate 411a-1a and a plurality of reinforcing beams 411a-1b installed at the bottom of the flat plate 411a-1a. The structural form of the reinforcing beam 411a-1b may be various, such as a combination of beams staggered horizontally and vertically. Of course, other structures may also be used as long as the technical effect of reinforcing the flat plate 411a-1a can be achieved. The lattice beam section 411a-2 may include a plurality of small cross beams 411a-2a spaced apart along the longitudinal direction. Two adjacent small cross beams 411a-2a along the longitudinal direction may be connected by a connecting plate 411a-2b.

[0166] With this design, there is a gap between two adjacent small cross beams 411a-2a of the grid beam section 411a-2, which can facilitate the installation of a shield to limit the wheels of road vehicles; and the flat beam section 411a-1 can be used as a parking position for the semi-trailer legs, so as to cooperate with the leg bottom plate, thereby reliably supporting the semi-trailer legs.

[0167] It should be pointed out that the embodiment of the present invention does not limit the proportion of the longitudinal beam 411a and the transverse beam 411b in the transverse direction of the middle wall 411, and also does not limit the proportion of the flat beam section 411a-1 and the grating beam section 411a-2 in the longitudinal direction of the longitudinal beam 411a. During specific implementation, those skilled in the art can make settings according to actual needs.

[0168] The bottom wall 41 may also include an inclined wall 413 which gradually inclines upward from the inside to the outside, and the inclined wall 413 is located on both sides of the middle wall 411 in the horizontal direction, and is used to connect the middle wall 411 and the side wall 42. The function of the inclined wall 413 is similar to that of the aforementioned inclined plate portion 412b-3, and both can be used to guide the tires of the road vehicle to ensure that the tires of the road vehicle stay on the two longitudinal beams 411a as much as possible; in the scheme of the attached drawings, the longitudinal ends of the inclined wall 413 can be connected to the aforementioned inclined plate portion 412b-3.

[0169] The lower end surface of the support part 4 is provided with a first positioning part, and the upper end surface of the translation part 600 is provided with a second positioning part matched with the first positioning part. When the translation part 600 moves to the bottom of the support part 4, the first positioning part corresponds to the second positioning part, and then the support part 4 is lowered and fixed to the translation part 600 through the cooperation of the first positioning part and the second positioning part, so that the support part 4 can be prevented from moving relative to the translation part 600 during the translation process, and it can also ensure that when the translation part 600 moves into or out of the track 100, it can drive the support part 4 to the corresponding bottom frame and the loading and unloading station, thereby ensuring stability and accuracy.

[0170] Specifically, there is no restriction on the structure of the first and second positioning parts. For example, the first positioning part can be set as a positioning hole and the second positioning part can be set as a positioning pin, or the first positioning part can be set as a positioning pin and the second positioning part can be set as a positioning hole. Fig.13 As shown, the positioning portion 412 a - 1 can be set on the bottom surface of the end wall 412 .

[0171] Main body part 1

[0172] Based on the above-mentioned support part 4, the structure of the main body 1 of the saddlebag provided by the present invention is not actually limited, as long as it can have the aforementioned end connection mechanism 22 to cooperate with the connection structure at the longitudinal ends of the support part 4.

[0173] According to the number of supporting parts 4 included in each section of the vehicle body, the vehicle body can be divided into two types:

[0174] First, if Figure 5As shown, the number of the supporting part 4 can be one, the chassis is an end chassis 2, the number of the end chassis 2 is two, a bogie can be provided under each of the two end chassis 2, both end chassis 2 can be provided with the aforementioned end connecting mechanism 22, and the supporting part 4 can be installed between the two end chassis 2.

[0175] Secondly, the number of the supporting parts 4 can be multiple, and the chassis is divided into the end chassis 2 and the joint chassis 3, wherein the number of the end chassis 2 is two, and the number of the joint chassis 3 is at least one. Due to the axle weight limit, the number of the supporting parts 4 is usually not more than two. When the number of the supporting parts 4 is two, the number of the joint chassis 3 is one. The joint chassis 3 can include two joint chassis divisions 3a, which are connected by joints and located between the two end chassis 2. A bogie is respectively provided under the two end chassis 2, and a bogie can be shared under the two joint chassis divisions 3a. The two supporting parts 4 can be respectively installed between the adjacent end chassis 2 and the joint chassis divisions 3a; in this way, the longitudinal length of each car body can be more fully utilized to increase the cargo capacity of the car body, thereby effectively reducing the transportation cost.

[0176] As for the end chassis 2, it may include the above-mentioned end connection mechanism 22. The specific structural form is referred to in Figure 16-29 , Fig.16 It is a structural diagram of two end chassis installed on the bogie and connected to each other; Fig.17 It is a structural diagram of the end chassis body and the end connection mechanism; Fig.18 for Fig.17 A side view of the middle structure mounted on the bogie and connected to the bracket; Fig.19 for Fig.17 Exploded view of; Fig. 20 for Fig.17 An enlarged view of the longitudinal support member at the middle end; Fig.21 for Fig.17 An enlarged view of the lateral stopper at the middle end; Fig. 22 for Fig.17 A magnified view of the first component; Fig.23 for Fig.17 A magnified view of the second component; Fig.24 for Fig.17 A magnified view of the third component; Fig.25 for Fig.17 Enlarged view of the third and fourth longitudinal beams; Fig.26 for Fig.17 An enlarged view of the first and second bolsters; Fig. 27 for Fig.17 An enlarged view of one of the end side bearings; Fig.28 for Fig.17 An enlarged view of a container lock seat; Fig.29 for Fig.17An enlarged view of a set of reinforcement plates.

[0177] like Fig.16 As shown, when there are multiple car bodies, two adjacent car bodies can be connected by two end chassis 2. In the figure, the two end chassis 2 are connected by a coupler. In addition, a bogie is arranged under each end chassis 2, that is, one end chassis 2 is correspondingly mounted on one bogie.

[0178] Combination Fig.17 The end connecting mechanism 22 is connected to the rear end of the end chassis body 21. The definition of front and rear is mainly determined in combination with the perspective in the attached drawings. In fact, since each car body includes two symmetrically arranged end chassis 2, the front and rear and left and right positional relationships of the two end chassis 2 are actually opposite. Fig.16 Understand the markings related to front, back, left and right.

[0179] The end connection mechanism 22 comprises an end connection hook 221. The hook opening of the end connection hook 221 faces upward, and an end groove 221a extending in the transverse direction is provided on the inner hook surface of the end connection hook 221.

[0180] like Fig. 20 As shown, in the connected state, the lower circular shaft 412c of the support part 4 is placed in the end groove 221a, and is supported by the upward support force from the inner surface of the end groove 221a, so that the vertical direction is effectively supported. At the same time, the inner surface of the end groove 221a can also play a certain longitudinal limiting role on the lower circular shaft 412c. Therefore, the end chassis 2 and the support part 4 have good connection reliability. Moreover, by applying an upward lifting force to the support part 4, the lower circular shaft 412c can be disengaged from the end groove 221a, which facilitates the separation of the end chassis 2 and the support part 4.

[0181] Further, such as Fig.17 As shown, the end connection mechanism 22 further includes an end longitudinal support member 222 , and the end longitudinal support member 222 is located above the end connection hook 221 , specifically, it can be directly above or obliquely above.

[0182] like Fig. 20 As shown, the end longitudinal support member 222 includes an end longitudinal support body 222a and end wear plates 222b fixed to the front and rear ends of the end longitudinal support body 222a.

[0183] like Figure 6 As shown, an upper hook 421 is provided at the end of the support portion 4, and the hook mouth of the upper hook 421 faces downward.

[0184] like Fig.18As shown, in the connected state, the end longitudinal support body 222a extends into the hook opening of the upper hook 421, and the two are hooked together. At the same time, the end wear plate 222b at the front end abuts against the front side of the inner hook surface of the upper hook 421, and the end wear plate 222b at the rear end abuts against the rear side of the inner hook surface of the upper hook 421, thereby playing a longitudinal supporting role for the support part 4. In this way, the connection reliability between the end chassis 2 and the support part 4 can be further improved, and the convenience of separating the end chassis 2 and the support part 4 will not be affected.

[0185] like Fig. 20 As shown, the upper part of the end wear plate 222b at the front end is tilted backward relative to the lower part, and the upper part of the end wear plate 222b at the rear end is tilted forward relative to the lower part. At the same time, the inner surface of the end groove 221a forms an end guide surface, which can guide the fall of the support part 4 during installation when matched with the lower circular shaft 412c, and the end guide surface can also match with the lower circular shaft 412c to guide the rotation and separation of the support part 4 and the main body 1.

[0186] Specifically, when the support portion 4 is connected to the end chassis 2, the end guide surface can guide the lower circular shaft 412c to gradually slide into the end connecting hook 221 to guide the installation of the support portion 4, and when the support portion 4 continues to fall, the clamping degree of the end longitudinal support body 222a and the upper hook 421 can be gradually increased, so that the upper hook 421 can firmly hook the end longitudinal support body 222a; when the support portion 4 is separated from the end chassis 2, an upward lifting force ( Fig.18 When the end chassis 2 is lifted to a certain height, the end chassis 2 rotates counterclockwise with the central axis of the lower circular shaft 412c as the rotation center under the guidance of the inner surface of the end groove 221a, so that the end longitudinal support body 222a and the upper hook 421 are released, thereby facilitating the separation of the end chassis 2 and the support 4. In short, such a configuration can improve the connection reliability and separation convenience of the end chassis 2 and the support 4.

[0187] In the illustrated embodiment, the top of the end longitudinal support body 222a is a trapezoidal structure with a small top and a large bottom (see Fig. 20 ), the height position of the end wear plate 222b at the rear end is lower than the height position of the end wear plate 222b at the front end, so that the end chassis 2 can smoothly produce the above counterclockwise rotation without interference. Of course, the structure for avoiding interference is not limited to this and can be reasonably adjusted in actual implementation. Fig. 20 In the figure, the end wear plate 222b is connected to the end longitudinal support body 222a by bolts and nuts. The end longitudinal support body 222a is a hollow structure and has an oblong hole at the bottom, so that the end wear plate 222b can be easily replaced.

[0188] In the illustrated embodiment, the end groove 221a is a cylindrical groove (see Fig.17 ), so that its inner surface can play the above-mentioned guiding role when cooperating with the cylindrical lower round shaft 412c. Of course, in actual implementation, the end groove 221a is not limited to a cylindrical groove.

[0189] Further, such as Fig.17 As shown, the end connection mechanism 22 also includes an end transverse limiter 223, which is a limit guide member arranged on the end base frame 2 and cooperates with the guide limiter 422 of the support portion 4. The end transverse limiter 223 is located above the end connection hook 221, specifically, it can be directly above or obliquely above, and the end transverse limiter 223 is located in front of the end longitudinal support member 222, specifically, it can be directly in front or obliquely in front.

[0190] like Fig.21 As shown, the end transverse limiting member 223 includes an end transverse limiting groove 223a.

[0191] Combination Fig.18 In the connected state, the guide limiter 422 is inserted into the end transverse limiter groove 223a, and the left and right groove walls of the end transverse limiter groove 223a are respectively located on the left and right sides of the guide limiter 422 to limit the transverse position of the guide limiter 422. In this way, the connection reliability between the end chassis 2 and the support 4 can be further improved.

[0192] In the illustrated embodiment, the upper portion of the left groove wall and / or the upper portion of the right groove wall of the end transverse limiting groove 223a can form a left guide surface 223b and a right guide surface 223c respectively (see Fig.21 ), the upper side of the left guide surface 223b is inclined to the left relative to the lower side, and the upper side of the right guide surface 223c is inclined to the right relative to the lower side, so that the guide limit member 422 can be guided into the end transverse limit groove 223a.

[0193] Fig.21 In the embodiment, the end transverse limiter 223 is composed of a U-shaped plate and two rib plates. In actual implementation, the structure of the end transverse limiter 223 is not limited to this.

There are also two end transverse limit members 223, one fixed to the upper side of the left end of the second beam 2102, and the other fixed to the upper side of the right end of the second beam 2102.

[0197] like Fig.23 As shown, the first transverse beam 2101 , the first longitudinal beam 2103 , the second longitudinal beam 2104 and the impact seat 2110 constitute the second component.

The end traction beam 2109 includes a traction upper plate and a traction lower plate arranged in parallel, and a traction web arranged therebetween, and the traction upper plate is provided with a plate opening for the saddle mounting seat 2114 to be exposed.

[0199] like Fig.25As shown, the third longitudinal beam and the fourth longitudinal beam have the same structure, both comprising a trough beam with a notch facing upward, a cover plate covering the notch of the trough beam, and a round tube transversely passing through the trough beam.

[0200] like Fig.26 As shown, the first bolster and the second bolster have the same structure, both comprising an upper bolster plate, a lower bolster plate, two bolster webs and two bolster partitions.

[0201] like Fig.19 As shown, the structures of the two end side bearings are the same. Fig. 27 As shown, the end side bearing includes a side bearing bottom plate, three side bearing vertical plates, a side bearing adjustment pad plate and a side bearing wear plate. The three side bearing vertical plates are connected above the side bearing bottom plate and the three are connected in an I-shaped shape. The side bearing adjustment pad plate is connected below the side bearing bottom plate, and the side bearing wear plate is connected below the side bearing adjustment pad plate. The three are connected together by bolts, nuts and washers.

[0202] Further, such as Fig.17 As shown, the end chassis body 21 further includes two container lock seats 2111. One container lock seat 2111 is fixed to the third longitudinal beam 2105, the first bolster beam 2107 and the upper side of the second cross beam 2102, and the other container lock seat 2111 is fixed to the fourth longitudinal beam 2106, the second bolster beam 2108 and the upper side of the second cross beam 2102, and can be fixed by welding.

[0203] like Fig.28 As shown, the container lock seat 2111 includes a horizontally arranged container bottom plate, longitudinal container upright plates connected to the left and right sides of the container bottom plate, and three transverse container upright plates connected between the two longitudinal container upright plates, one transverse container upright plate is located at the end of the container bottom plate, and the other two transverse container upright plates are located in the middle of the container bottom plate. A rib plate is provided between the two transverse container upright plates in the middle and the container bottom plate, and the rib plate is located between the two transverse container upright plates in the middle.

[0204] Further, such as Fig.19 As shown, the end chassis body 21 also includes a reinforcing plate 2113 . Fig.19 There are two sets of reinforcing plates 2113, one set is connected between the second cross beam 2102 and the third longitudinal beam 2105, and the other set is connected between the second cross beam 2102 and the fourth longitudinal beam 2106. The two sets of reinforcing components 2113 have the same structure. Fig.29 As shown, each group of reinforcement components 2113 includes a transverse rib plate and two triangular rib plates.

[0205] The structure of the joint chassis 3 is similar to that of the end chassis 2, especially at the end connection mechanism 22. Fig.30 This is the structural diagram of the joint chassis. Fig.31 for Fig.26 Side view of the structure mounted on the bogie and connected to the bracket, Fig.32 for Fig.30 A structural diagram of a joint chassis section.

Fig.41 for Fig.35 An enlarged view of a set of reinforcement plates.

[0206] like Fig.30 As shown, the joint chassis section 3a includes a joint chassis body 31, a joint connection mechanism 32 and a joint 33. The joint connection mechanism 32 is an end connection mechanism 3 installed on the joint chassis 3, which is fixed at the rear end of the joint chassis body 31, and the joint 33 is fixed at the front end of the joint chassis body 31. It should be noted that the ends of the two joint chassis sections 3a that are close to each other are the front ends of the two, and the ends that are away from each other are the rear ends of the two. When in use, the joints 33 of the two joint chassis sections 3a are connected by joint bearings. In the connected state, the two joint chassis sections 3a can rotate horizontally and vertically to meet the flexibility requirements of the vehicle when turning and walking on a ramp.

[0207] like Fig.31 As shown, when used, each joint frame section 3a is connected to a support portion 4, so that two adjacent support portions 4 are connected through the joint frame 3, and a bogie is provided under the two joint frame sections 3a, that is, two joint frame sections 3a (one joint frame 3) are correspondingly installed on a bogie.

[0208] like Fig.32 and Fig.34 As shown, the structures of the joints 33 of the two joint chassis divisions 3a are different. The joint 33 of one joint chassis division 3a is set as a concave joint, and the joint of the other joint chassis division 3a is set as a convex joint. In the connected state, the convex joint extends into the concave joint to achieve a rotatable connection.

[0209] The joint connection mechanisms 32 of the two joint chassis divisions 3a have the same structure, and the joint chassis bodies 31 also have the same structure. In the connected state, the joint connection structures 32 of the two are relatively laterally symmetrical, and the joint chassis bodies 31 of the two are also relatively laterally symmetrical. The specific structure of the joint connection mechanism 32 is first described below, and then the specific structure of the joint chassis body 31 is described.

[0210] like Fig.32 As shown, the joint connection mechanism 32 includes a joint connection hook 321. The hook mouth of the joint connection hook 321 faces upward, and a joint groove 321a extending in the transverse direction is provided on the inner hook surface of the joint connection hook 321.

[0211] like Fig.31 As shown, in the connected state, the lower circular shaft 412c of the support part 4 is placed in the joint groove 321a, and is supported by the upward support force from the inner surface of the joint groove 321a, so that the vertical direction is effectively supported. At the same time, the inner surface of the joint groove 321a can also play a certain longitudinal limiting role on the lower circular shaft 412c. Therefore, the joint chassis 3 and the support part 4 have good connection reliability. Moreover, the support part lifting part applies an upward lifting force to the support part 4, so that the lower circular shaft 412c can be disengaged from the joint groove 321a, which facilitates the separation of the joint chassis 3 and the support part 4.

[0212] Further, such as Fig.32 As shown, the joint connection mechanism 32 further includes a joint longitudinal support member 322 , and the joint longitudinal support member 322 is located above the joint connection hook 321 , specifically, it can be directly above or obliquely above.

[0213] like Fig.36 As shown, the joint longitudinal support member 322 includes a joint longitudinal support body 322a and joint wear plates 322b fixed to the front and rear ends of the joint longitudinal support body 322a.

[0214] like Figure 6 As shown, an upper hook 421 is provided on the upper side of the end of the support portion 4, and the hook mouth of the upper hook 421 faces downward.

[0215] like Fig.31 As shown, in the connected state, the end longitudinal support body 322a extends into the hook opening of the upper hook 421, and the two are hooked together. At the same time, the joint wear plate 322b at the front end abuts against the front side of the inner hook surface of the upper hook 421, and the joint wear plate 322b at the rear end abuts against the rear side of the inner hook surface of the upper hook 421, thereby playing a longitudinal supporting role for the support part 4. In this way, the connection reliability between the joint base frame 3 and the support part 4 can be further improved, and the convenience of separating the joint base frame 3 and the support part 4 will not be affected.

[0216] like Fig.36As shown, the upper part of the joint wear plate 322b at the front end is tilted backward relative to the lower part, and the upper part of the joint wear plate 322b at the rear end is tilted forward relative to the lower part. At the same time, the inner surface of the joint groove 321a forms a joint guide surface, which can guide the fall of the support part 4 during installation when cooperating with the lower circular shaft 412c, and the joint guide surface can also cooperate with the lower circular shaft 412c to guide the rotation and separation of the support part 4 and the joint chassis 3.

[0217] Specifically, when the support portion 4 is connected to the joint chassis 3, the joint guide surface can guide the lower circular shaft 412c to gradually slide into the joint connecting hook 321 to guide the installation of the support portion 4, and when the support portion 4 continues to fall, the clamping degree of the joint longitudinal support body 322a and the upper hook 421 can be gradually increased, so that the upper hook 421 can firmly hook the joint longitudinal support body 322a; when the support portion 4 is separated from the joint chassis 3, an upward lifting force ( Fig.31 When the joint base frame 3 is lifted to a certain height, the joint base frame 3 is guided by the inner surface of the joint groove 321a and rotates with the central axis of the lower circular shaft 412c as the rotation center, so that the joint longitudinal support body 322a and the upper hook 421 are released, thereby facilitating the separation of the joint base frame 3 and the support part 4. In short, such a configuration can improve the connection reliability and separation convenience of the joint base frame 3 and the support part 4.

[0218] In the illustrated embodiment, the top of the joint longitudinal support body 322a is a trapezoidal structure with a small top and a large bottom (see Fig.36 ), the height position of the joint wear plate 322b at the rear end is lower than the height position of the joint wear plate 322b at the front end, so that the joint chassis section 3a can smoothly produce the above-mentioned lateral rotation without interference. Of course, the structure for avoiding interference is not limited to this, and can be reasonably adjusted in actual implementation. Fig.36 In the figure, the joint wear plate 322b is connected to the joint longitudinal support body 322a by bolts and nuts. The joint longitudinal support body 322a is a hollow structure and an oblong hole is provided at the bottom, so that the joint wear plate 322b can be easily replaced.

[0219] In the illustrated embodiment, the joint groove 321a is a cylindrical groove (see Fig.32 ), so that its inner surface can play the above-mentioned guiding role when cooperating with the cylindrical lower round shaft 412c. Of course, in actual implementation, the joint groove 321a is not limited to a cylindrical groove.

[0220] Further, such as Fig.32As shown, the joint connection mechanism 32 also includes a joint transverse limiter 323, which is a limit guide member arranged on the joint base frame 3 and cooperates with the guide limiter 422 of the support part 4. The joint transverse limiter 323 is located above the joint connection hook 321, specifically, it can be directly above or obliquely above, and the joint transverse limiter 323 is located in front of the joint longitudinal support member 322, specifically, it can be directly in front or obliquely in front.

[0221] like Fig.37 As shown, the joint transverse limiting member 323 includes a joint transverse limiting groove 323a.

[0222] like Fig.31 As shown, in the connected state, the guide limiter 422 is inserted into the joint transverse limiter groove 323a, and the left groove wall and the right groove wall of the joint transverse limiter groove 323a are respectively located on the left and right sides of the guide limiter 422 to limit the transverse position of the guide limiter 422. In this way, the connection reliability between the joint chassis 3 and the support part 4 can be further improved.

[0223] In the illustrated embodiment, the upper portion of the left groove wall and / or the upper portion of the right groove wall of the joint transverse limiting groove 323a respectively forms a left guide surface 323b and a right guide surface 323c (see Fig.37 ), the upper side of the left guide surface 323b is inclined to the left relative to the lower side, and the upper side of the right guide surface 323c is inclined to the right relative to the lower side, so that the guide limit member 422 can be guided into the joint transverse limit groove 323a.

[0224] Fig.37 In the embodiment, the joint transverse limiter 323 is composed of a U-shaped plate and two rib plates. In actual implementation, the structure of the joint transverse limiter 323 is not limited to this.

[0225] like Fig.32 and Fig.33 As shown, the joint chassis body 31 includes a first joint cross beam 3101 , a second joint cross beam 3102 , a third joint cross beam 3103 , a first joint longitudinal beam 3104 , a second joint longitudinal beam 3105 , a joint traction beam 3106 , a first joint floor 3107 , and a second joint floor 3108 .

[0226] The first joint cross beam 3101 is arranged behind the second joint cross beam 3102 and the third joint cross beam 3103, the left end of the first joint cross beam 3101 is fixed to the left end of the second joint cross beam 3102 through the first joint longitudinal beam 3104, the right end of the first joint cross beam 3101 is fixed to the right end of the third joint cross beam 3103 through the second joint longitudinal beam 3105, the right end of the second joint cross beam 3102 and the left end of the third joint cross beam 3103 are respectively fixed to the front end of the joint traction beam 3106, so as to form a joint frame; the rear end of the joint traction beam 3106 is fixed to the first joint cross beam 3101; the fixing method between the beams can be welding. The joint 33 is fixed to the front end of the joint traction beam 3106, which can be specifically fixed by welding.

[0227] The first joint floor 3107 and the second joint floor 3108 cover the top frame of the joint frame and are respectively located on the left and right sides of the joint traction beam 3106. The first joint floor 3107 is fixed to the second joint cross beam 3102, the first joint longitudinal beam 3104 and the joint traction beam 3106. The second joint floor 3108 is fixed to the third joint cross beam 3103, the second joint longitudinal beam 3105 and the joint traction beam 3106, and can be specifically fixed by welding.

[0228] like Fig.38 As shown, the first joint beam 3101 and the joint connecting hook 321 form a first component. In the figure, two joint connecting hooks 321 are provided, one is fixed to the lower left end of the first joint beam 3101, and the other is fixed to the lower right end of the first joint beam 3101. Fig.32 There are also two joint longitudinal support members 322, one fixed to the rear side of the left end of the first joint beam 3101, and the other fixed to the rear side of the right end of the first joint beam 3101; there are also two joint transverse limit members 323, one fixed to the upper side of the left end of the first joint beam 3101, and the other fixed to the upper side of the right end of the first joint beam 3101.

[0229] In a specific solution, the second joint cross beam 3102 and the third joint cross beam 3103 have the same structure, both including a bottom plate, a double web plate and a partition plate arranged between the double web plates (see Fig.39 The first joint longitudinal beam 3104 and the second joint longitudinal beam 3105 have the same structure, both of which are grooved beams with the notches facing upwards (see Fig.35 The first joint floor 3107 and the second joint floor 3108 have the same structure, both of which are plate structures with a hole in the center. The joint traction beam 3106 includes a traction upper cover plate and a traction lower cover plate and a traction vertical plate arranged therebetween.

[0230] Further, such as Fig.32As shown, the joint chassis body also includes two joint side bearings 3109, which are respectively located on the left and right sides of the joint 33, one joint side bearing 3109 is fixed to the front side of the second joint cross beam 3102, and the other joint side bearing 3109 is fixed to the front side of the third joint cross beam 3103. In a specific solution, the structures of the two joint side bearings 3109 are the same. Fig.40 As shown, the joint side bearing includes a side bearing lower cover plate, a side bearing upper cover plate and a side bearing vertical plate arranged therebetween.

[0231] Further, such as Fig.32 As shown, the joint chassis body 31 also includes a reinforcement plate 3110. In the specific solution, two sets of reinforcement plates 3110 are provided (see Fig.35 ), one group of reinforcing plates 3110 is fixed between the first joint floor 3107 and the first joint cross beam 3101, and another group of reinforcing plates is fixed between the second joint floor 3108 and the first joint cross beam 3101. Fig.41 As shown, each group of reinforcement components 3110 includes a transverse rib plate and two triangular rib plates.

[0232] The end frame 2 and the joint frame 3 may be installed with a locking mechanism 5, which can realize locking or unlocking of the vertical support portion 4 and the main body 1. The installation positions of the locking mechanism 5 on the end frame 2 and the joint frame 3 are similar.

[0233] In the end chassis 2, combine Fig. 22 The end connecting hook 221 includes an end hook body 221b, and the end hook body 221b includes two end hook sub-bodies 221b-1 arranged in a transverse interval and an end accommodating cavity 221b-2 formed between the two end hook sub-bodies 221b-1, and the locking mechanism 4 can be installed in the end accommodating cavity 221b-2. Fig. 22 In the embodiment, the end connecting hook 221 also includes an end hook wall plate 221c covering the outer hook surface of the end hook body 221b, and the end hook wall plate 221c is provided with an end first connecting hole 221d, and the end first connecting hole 221d is communicated with the end accommodating cavity 221b-2. The chassis lifting part is provided with a first unlocking part 77. When the end chassis 2 is lifted by the chassis lifting part, the first unlocking part 77 can extend into the end accommodating cavity 221b-2 through the end first connecting hole 221d to unlock the locking mechanism 5. After unlocking, the support part 4 can be separated from the end chassis 2. In addition, Fig. 22 In the embodiment, the end connecting hook 221 is further provided with an end second connecting hole 221e.

[0234] In the joint base 3, the joint connecting hook 321 includes a joint hook body 321b, which includes two joint hook parts 321b-1 arranged laterally and a joint accommodating cavity 321b-2 formed between the two joint hook parts 321b-1, and the locking mechanism 5 can be installed in the joint accommodating cavity 321b-2. Fig.38 In the figure, the joint connecting hook 321 also includes a joint hook wall plate 321c covered on the outer hook surface of the joint hook body 321b, and the joint hook wall plate 321c is provided with a joint first connecting hole 321d, and the joint first connecting hole 321d is communicated with the joint accommodating cavity 321b-2. When the joint base frame 3 is lifted by the base frame lifting part, the first unlocking part 77 can extend into the above-mentioned joint accommodating cavity 321b-2 through the joint first connecting hole 321d to unlock the locking mechanism 5. After unlocking, the supporting part 4 can be separated from the joint base frame 3.

[0235] That is to say, when the base frame is lifted by the base frame lifting part, the lock between the base frame and the supporting part 4 can be unlocked at the same time, and then the supporting part 4 can be directly lifted by the supporting part lifting part without setting additional unlocking components, which is more convenient to operate.

[0236] Since the installation structures of the locking mechanism on the end frame 2 and the joint frame 3 are similar, the following description of the specific structure of the locking mechanism is based on the example of the installation on the end frame 2, and for the locking mechanism 5, this embodiment provides two structures of the locking mechanism 5.

[0237] The first locking mechanism 5 can refer to Figure 42-48 , Fig.42 This is a structural diagram of the first locking mechanism installed on the end connecting hook; Fig.43 It is a structural diagram of the end connecting hook, the support part and the first locking mechanism in a locked state; Fig.44 for Fig.43 Side view of Fig.45 for Fig.43 Side view in unlocked state; Fig.46 is a structural diagram of the connection between the first lock body and the first locking drive beam assembly; Fig.47 for Fig.46 Exploded view of; Fig.48 It is a structural diagram of the first limiting part, the second limiting part and the first guide sleeve fixed to the end connecting hook.

[0238] like Figure 42-48As shown, the locking mechanism 5 includes: a first lock body 51, the first lock body 51 is hinged to the end connecting hook 221 through a third hinge shaft 52, one end of the first lock body 51 is a locking end 511, and the other end is a first limiting end 512, and the third hinge shaft 52 is located between the locking end 511 and the first limiting end 512; a first limiting portion 53, the first limiting portion 53 is fixed in the end accommodating cavity 221b-2 (see Fig.48 );

[0239] A first locking driving beam assembly 54 connected to the first lock body 51;

[0240] In the locked state, Fig.44 As shown, the first limiting end portion 512 abuts against the first limiting portion 53 from top to bottom, and the locking end portion 511 abuts against the supporting portion 4 to lock the supporting portion 4; in the unlocked state, as shown Fig.45 As shown, the first locking drive beam assembly 54 can drive the first limiting end portion 512 to separate from the first limiting portion 53 from bottom to top, and the locking end portion 511 to rotate and separate from the supporting portion 4.

[0241] Using this structure, Fig.44 , Fig.45 As shown, when locking, if there is a separation tendency between the supporting portion 4 and the end connecting hook 221, the supporting portion 4 will generate an upward force on the locking end 511 to drive the locking end 511 to rotate counterclockwise, and the supporting force from bottom to top generated by the first limiting portion 53 on the first limiting end 512 can block the first lock body 51 from rotating in the counterclockwise direction, thereby ensuring that the position of the locking end 511 remains unchanged, and the supporting portion 4 can be reliably locked; when unlocking, the first locking drive beam assembly 54 can drive the first limiting end 512 to separate from the first limiting portion 53 from bottom to top, and the first lock body 51 can rotate clockwise, and its rotation direction is opposite to the stop direction of the first limiting portion 53, and the locking end 511 and the supporting portion 4 can be separated smoothly, so that the supporting portion 4 can be smoothly unlocked without affecting the separation of the supporting portion 4 and the end connecting hook 221.

[0242] Here, the embodiment of the present invention does not limit the structure of the first limiting portion 53, which may be plate-shaped or block-shaped; similarly, the embodiment of the present invention does not limit the number of the first limiting portions 53, which may be one or include multiple independent limiting members, as long as it can achieve the above-mentioned technical effects.

[0243] In a detailed scheme, Fig.46 As shown, the first locking driving beam assembly 54 may include a first push beam 541, a first guide sleeve 542 and a transmission beam 543. The first guide sleeve 542 is fixed in the end receiving cavity 221b-2 (see the attached Fig.48), the first push beam 541 and the first guide sleeve 542 can be slidably connected, one end of the transmission beam 543 can be hinged to the first lock body 51, and the other end can be hinged to the first push beam 541.

[0244] In this way, when the first push beam 541 moves upward due to the driving force, the hinged transmission beam 543 can convert the linear motion of the first push beam 541 into the rotational motion of the first lock body 51, so as to transmit the unlocking driving force to the first lock body 51, thereby realizing the unlocking of the first lock body 51; and when the driving force disappears, relying on its own gravity, etc., the first push beam 541 can automatically slide down along the first guide sleeve 542 and drive the first lock body 51 to rotate in the opposite direction, so as to realize the automatic locking of the first lock body 51. Of course, the reverse driving force can also be provided by an external device to drive the first push beam 541 to reset and lock.

[0245] Specifically, the first push beam 541 may be directly opposite to the first connection hole 221d at the end (see Fig.40 and Fig.41 ) so that the unlocking component (first unlocking portion 77) can pass through the first connecting hole 221d at the end and contact the first push beam 541, thereby applying an upward unlocking driving force to the first push beam 541.

[0246] It should be pointed out that the embodiment of the present invention does not limit the source of the driving force exerted on the first push beam 541 when it is unlocked. It can adopt a manual driving solution. For example, an unlocking component such as an unlocking rod can be provided. When unlocking is required, the staff can manually operate the unlocking component to generate a driving force for the first push beam 541. Alternatively, an automatic driving solution can be adopted. In this case, the power source can be a motor, a cylinder, an oil cylinder, etc. These power sources can be installed on the vehicle body or on ground equipment. The specific selection can be made according to actual conditions. A transmission mechanism can also be provided between the power source and the first push beam 541 to transmit the driving force of the power source.

[0247] The beam section of the first push beam 541 located above the first guide sleeve 542 may also be provided with a first connecting sleeve 541a. Fig.43 As shown, the first connecting sleeve 541a can specifically be a U-shaped plate, the bottom plate portion of the U-shaped plate can be connected to the first push beam 541, and can form a support with the first guide sleeve 542 to serve as a limiting component for the downward movement of the first push beam 541, and the transmission beam 543 can be hinged between the two side plate portions of the U-shaped plate.

[0248] In fact, the downward movement limit of the first push beam 541 can also be achieved through the cooperation of the first limit end 512 and the first limit part 53. In this way, the above-mentioned first connecting sleeve 541a may not exist; or, the transmission beam 543 can also be used for limiting. The transmission beam 543 and the first push beam 541 adopt a hinged connection scheme. The two are usually set at an angle during actual working. The transmission beam 543 can also serve as a limiting component for the downward movement of the first push beam 541.

[0249] In the above scheme, the linear motion of the first push beam 541 is converted into the rotational motion of the first lock body 51 through the transmission beam 543. In fact, in addition to this scheme, other schemes can also be adopted. For example, a guide hole can be set on the first lock body 51, and the first push beam 541 can be hinged in the guide hole. When the first push beam 541 produces axial displacement, the hinge shaft of the first push beam 541 can slide in the guide hole to naturally drive the first lock body 51 to rotate, which can also realize the conversion of linear motion into rotational motion.

[0250] Furthermore, the locking mechanism 5 may also include a locking first elastic member 541b, one end of which may act on the first push beam 541, and the unlocking process is a process in which the deformation of the locking first elastic member 541b increases to gather elastic force. With such a configuration, when the driving force acting on the first push beam 541 disappears, the elastic force of the locking first elastic member 541b may be released to cooperate with the gravity of the first push beam 541 itself to jointly drive the first lock body 51 to reset and lock.

[0251] Specifically, the first elastic member 541b for locking can be a spring, which can be installed in a sleeve on the first push beam 541, and the lower end of the first push beam 541 can be provided with a first support member 541c, and the two ends of the spring can interact with the first guide sleeve 542 and the first support member 541c respectively. Among them, the first push beam 541 can act as a spring column, which is conducive to preventing the radial movement of the spring during the expansion and contraction process, and has a positive effect on improving the stability of the structure and the reliability of power transmission; and with this structure, in the unlocked state, the first push beam 541 can move upward, and the first elastic member 541b for locking can be compressed, and when restoring the lock, the first push beam 541 can move downward, and the first elastic member 541b for locking can be released.

[0252] In fact, in the locked state, the locking first elastic member 541b can also have a certain amount of pre-compression, that is, the locking first elastic member 541b can still provide a certain elastic force when locked, which has a positive effect on ensuring the stability of the locking state of the first lock body 51, and can avoid the automatic unlocking of the first lock body 51 when the rail vehicle passes through a curve.

[0253] To facilitate adjustment of the pre-compression amount, the first support member 541c can be a nut. Thus, by changing the screwing position of the nut, the distance between the first support member 541c and the first guide sleeve 542 can be adjusted, thereby adjusting the pre-compression amount of the first elastic member 541b locked in the locked state.

[0254] In the unlocked state, the locking first elastic member 541b can actually be in a stretched state. At this time, the installation position of the locking first elastic member 541b can change. Specifically, it can be arranged between the first connecting sleeve 541a and the first guide sleeve 542, and its two ends can be fixedly connected to the first connecting sleeve 541a and the first guide sleeve 542 to transmit the pulling force.

[0255] The first lock body 51 may be provided with a mounting groove 513, and the transmission beam 543 may be hinged in the mounting groove 513, so that the thickness of the locking mechanism in the axial direction of the hinge axis between the transmission beam 543 and the first lock body 51 may be smaller, and the overall structure may be more compact. In addition, the mounting groove 513 may also be provided in the transmission beam 543, and then the first lock body 51 may be hinged in the mounting groove 513 of the transmission beam 543; or, the mounting groove 513 may not be provided, in which case the thickness of the assembly formed by the transmission beam 543 and the first lock body 51 in the axial direction of the hinge axis between the transmission beam 543 and the first lock body 51 may be relatively larger.

[0256] Furthermore, the locking mechanism 5 may also include a fixedly arranged second limiting portion 55, which may be fixed in the end accommodating cavity 221b-2, and its structure may be similar to that of the first limiting portion 53, and a repetitive description is not made here; the first lock body 51 may also include a second limiting end portion 514, and in the locked state, the second limiting end portion 514 may be against the second limiting portion 55 from bottom to top.

[0257] In this way, in the locked state, the first lock body 51 can form a three-point support solution, the force on the first lock body 51 is more balanced, and the first lock body 51 locks the support part 4 more reliably.

[0258] In detail, the first lock body 51 may include two locking arms set at an angle, and the two locking arms may roughly form an L-shape. The third hinge shaft 52 may be set at the connection between the two locking arms, that is, at the corner of the L-shape, wherein the end of one locking arm away from the third hinge shaft 52 may be a locking end 511, and the end of the other locking arm away from the third hinge shaft 52 may be a first limiting end 512; a small angle (<180 degrees) and a large angle (>180 degrees) are formed between the two locking arms, wherein the side where the small angle is located is the inner end of the connection, and the side where the large angle is located is the outer end of the connection, and the outer end can be used as the above-mentioned second limiting end 514.

[0259] Combination Fig.44 In the locked state, the first limiting portion 53 can generate a supporting force from bottom to top on the first limiting end 512, and the second limiting portion 55 can generate a supporting force from top to bottom on the second limiting end 514. Combined with the upward thrust generated by the supporting portion 4 on the locking end 511, the force on the first lock body 51 can be more balanced; moreover, through the interaction of the three force points, the third hinge shaft 52 is basically in a state of being unstressed, which has a positive effect on ensuring the reliability of the locking mechanism.

[0260] In the above-mentioned locking mechanism 5, in addition to the installation support point formed by the first guide sleeve 542, the first limiting portion 53, and the second limiting portion 55, the third hinge shaft 52 can also be used as an installation support point. Fig.47 The outer wall of the third hinge shaft 52 may be provided with a slot, in which a locking mounting plate 521 may be provided (the locking mounting plate 521 and the third hinge shaft 52 may also be directly connected by welding), and the locking mounting plate 521 may be connected to the end connecting hook 221 by a connecting member in the form of a bolt 522 or the like. Of course, in addition to the bolt connection, the locking mounting plate 521 and the end connecting hook 221 may also be fixedly connected by welding or the like.

[0261] The structure of the second locking mechanism 5 can be referred to Figure 49-58 , Fig.49 This is a structural diagram of the second locking mechanism installed on the end connecting hook; Fig.50 It is a structural diagram of the end connecting hook, the support part and the second locking mechanism in the locked state; Fig.51 It is a structural diagram of the end connecting hook, the support part and the second locking mechanism in the unlocked state; Fig.52 It is a structural diagram of the second guide sleeve, the fourth limiting part, and the rotating support body being fixed to the end connecting hook; Fig.53 is a structural diagram of the connection between the second push beam, the connecting beam unit and the second lock body; Fig.54 is a schematic structural diagram of a second connecting sleeve; Fig.55 It is a structural diagram of the transfer block;

[0262] Fig.56 It is a schematic diagram of the structure of the lock; Fig.57 is a structural schematic diagram of a second lock body; Fig.58 It is a schematic diagram of the structure of the rotating support body.

[0263] When locked, the locking mechanism 5 can lock the support part 4 and the end connecting hook 221 in the vertical direction to ensure the reliable connection between the two and driving safety. When unlocked, it does not affect the convenience of separating the support part 4 from the end connecting hook 221.

[0264] like Figure 49-58 As shown, the locking mechanism 5 includes: a lock head 51′, which is rotatably connected to the end connecting hook 221, and the lock head 51′ is provided with a locking portion 511′ and a supporting portion 512′ on both sides of its rotation center line; a second lock body 52′, which is slidably connected to the end connecting hook 221; a second locking drive beam assembly 53′, which is transmission connected to the second lock body 52′; in the locked state, the second lock body 52′ is supported by the supporting portion 512′ from bottom to top, so that the locking portion 511′ presses the supporting portion; in the unlocked state, the second locking drive beam assembly 53′ can drive the second lock body 52′ to move in a direction away from the lock head 51′, and the supporting portion 512′ can rotate downward around the rotation center line, so that the locking portion 511′ rotates upward to separate from the supporting portion.

[0265] With this structure, combined Fig.50 In the locked state, if the support portion and the end connecting hook 221 tend to separate, the support portion will generate an upward force on the locking portion 511' to drive the lock head 51' to rotate counterclockwise, and the second lock body 52' generates a bottom-up support force on the supporting portion 512', which can prevent the lock head 51' from rotating in the counterclockwise direction, thereby ensuring that the position of the locking portion 511' remains unchanged, and then the support portion 4 can be reliably locked; combined with Fig.51 When unlocking, the second locking drive beam assembly 53′ can drive the second lock body 52′ to slide in a direction away from the lock head 51′, the support portion 512′ can rotate downward around the rotation center line, and the locking portion 511′ can rotate upward to release the lock on the support portion without affecting the separation of the support portion 4 and the end connecting hook 221.

[0266] The rotation setting of the lock 51' can be specifically a hinge setting. In this case, a hinge shaft can be set for the lock 51', which can be fixed to the end connection hook 221 and located between the locking portion 511' and the support portion 512'. Alternatively, a rotation support body 54' can be set, which can be fixed to the end connection hook 221, and can be provided with a rotation shaft 541'. The rotation shaft 541' has an arc-shaped cylindrical surface, and the lock 51 can be provided with an arc-shaped notch 513' that matches the rotation shaft 541'. The matching here means that the outer diameter of the rotation shaft 541' is substantially consistent with the inner diameter of the arc-shaped notch 513'. During assembly, the lock 51' can be inserted into the rotation shaft 541' through the arc-shaped notch 513', and can be rotated with the central axis of the rotation shaft 541' as the rotation center line, so that the rotation setting of the lock 51' can also be realized.

[0267] When unlocking, the rotation of the lock head 51' can be achieved by the offset of the center of gravity. The center of gravity of the lock head 51' can be deviated from the rotation center line in the longitudinal direction and located on the side where the support portion 512' is located. Specifically, it can be referred to Fig.50 The arc-shaped notch 513' can be arranged on the right side of the center of gravity of the lock head 51', so that when the second lock body 52' moves to the left, the lock head 51' can naturally rotate counterclockwise to release the lock on the support portion.

[0268] And / or, a third elastic member in the form of a spring or the like may be provided for the lock head 51'. In the locked state, the third elastic member may gather elastic force in the form of a tensile force / compressive force or the like. When the second lock body 52' gradually moves away, the elastic force of the third elastic member may be released to drive the lock head 51' to automatically rotate and unlock. In comparison, both of the above-mentioned methods can realize the automatic rotation of the lock head 51' when unlocking. In specific implementation, those skilled in the art may select one according to actual needs.

[0269] Combination Fig.52 During the specific assembly, the number of the rotating support bodies 54′ can be two, so that the lock head 51′ can be mounted on the two rotating support bodies 54′, the installation stability of the lock head 51′ is higher, and the space between the two rotating support bodies 54′ can be used to insert the second lock body 52′, and the connection structure of the lock head 51′, the second lock body 52′ and the rotating support body 54′ can also be more compact.

[0270] For example Fig.58 As shown, the rotating support body 54′ may further include a third limiting portion 542′, which may be an angled shape, etc. In the unlocked state, the third limiting portion 542′ may abut against the support portion 512′ to limit the downward rotation of the support portion 512′. At the same time, it may also support a gap for the second lock body 52′ to be inserted from below the support portion 512′, so as to facilitate the reinsertion of the second lock body 52′, thereby supporting the support portion 512′.

[0271] Here, the embodiment of the present invention does not limit the supporting height of the third limiting portion 542′. During specific implementation, those skilled in the art can set it according to actual needs, as long as it is ensured that when the third limiting portion 542′ and the supporting portion 512′ are supported, the locking portion 511′ can unlock the supporting portion and at the same time reserve an insertion gap for the second lock body 52′.

[0272] Furthermore, if Fig.56 As shown, a support groove 514' may also be provided on the lock head 51', and when unlocking, the aforementioned third limiting portion 542' may be inserted into the support groove 514'. It can be understood that the depth of the third limiting portion 542' inserted into the support groove 514' actually determines the support height of the support portion 512' when unlocking. Therefore, in specific practice, the support height of the support portion 512' may also be adjusted by adjusting the depth of the support groove 514'.

[0273] Combination Fig.57 The second lock body 52′ may include an insertion section 521′ having an inclined guide surface. When locking, the insertion section 521′ may be inserted from below the support portion 512′ and may be supported by the support portion 512′ with the inclined guide surface, so as to gradually drive the support portion 512′ to rotate upward and the locking portion 511′ to rotate downward, and lock the support portion.

[0274] The second lock body 52′ may only include the insertion section 521′. Under this condition, when in the locked state, the second lock body 52′ may still be supported by the tilted guide surface and the support portion 512′, and when in the unlocked state, the second lock body 52′ may be completely separated from the support portion 512′, or the tilted guide surface may be supported by the support portion 512′. That is to say, when unlocking, the second lock body 52′ and the lock head 51′ may not be completely separated. At this time, the second lock body 52′ itself may also limit the rotation of the lock head 51′, and because the lock head 51′ is still on the second lock body 52′, there is no problem that the second lock body 52′ cannot be inserted, and the aforementioned third limiting portion 542′ may also not exist.

[0275] In the scheme of the accompanying drawings, Fig.57 For reference, the second lock body 52′ may include a three-part structure, namely a large-sized support segment 523′ with a larger vertical dimension, an insertion segment 521′ with a vertically variable dimension, and a small-sized support segment 524′ with a smaller vertical dimension. The large-sized support segment 523′ has a first support plane, and the small-sized support segment 524′ has a second support plane. In the locked state, the second lock body 52′ can be supported by the support portion 512′ through the first support plane, and in the unlocked state, the second lock body 52′ can be supported by the support portion 512′ through the second support plane.

[0276] Since the surface supporting the support portion 512′ is a plane, the stability of the lock head 51′ during unlocking and locking can be relatively high; and based on the above design, the support portion 512′ and the second lock body 52′ are not completely separated during unlocking, and the small-sized support section 524′ will naturally form a rotation limit for the support portion 512′, and the aforementioned third limit portion 542′ may also not exist.

[0277] As an attachment Fig.57 As a variation of the solution, the second lock body 52' may also only include a large-sized support segment 523' (or a small-sized support segment 524') and an insertion segment 521', which can also achieve the function of the second lock body 52'.

[0278] A guide structure may be provided between the second lock body 52 ′ and the rotating support body 54 ′ to guide the sliding direction of the second lock body 52 ′.

[0279] Specifically, in the second lock body 52' and the rotating support body 54', one may be provided with a slide groove 522', and the other may be provided with a sliding part matching the slide groove 522', and the sliding part may be inserted into the slide groove 522' and can slide along the slide groove 522'. The sliding part may be an integrated structure, such as the long strip slide rail 543' shown in the drawings, or may be a split structure, for example, it may include a plurality of sliders arranged at intervals.

[0280] Furthermore, a fourth position limiting portion 55' may be fixedly arranged, and the fourth position limiting portion 55' may be fixed in the end receiving cavity 221b-2. In the locked state, the fourth position limiting portion 55' may be tightly pressed against the supporting portion 512' from top to bottom.

[0281] In this way, in the locked state, the lock head 51′ can form a three-point support scheme, the force on the lock head 51′ is more balanced, and the locking of the support by the lock head 51′ can be more reliable; moreover, due to the interaction of the three force points, there is basically no force between the arc-shaped notch 513′ and the rotating shaft portion 541′, which has a positive effect on ensuring the reliability of the locking mechanism.

[0282] Here, the embodiment of the present invention does not limit the structure of the fourth limiting portion 55′, which can be plate-shaped or block-shaped; similarly, the embodiment of the present invention does not limit the number of the fourth limiting portion 55′, which can be one or include multiple independent limiting parts, as long as it can achieve the above-mentioned technical effects.

[0283] Please refer to Fig.53 , and combined with Fig.50 , Fig.51 In an exemplary embodiment, the second locking driving beam assembly 53' may include a second push beam 531', a second guide sleeve 532' and a connecting beam unit 533'. The second guide sleeve 532' may be fixedly arranged, specifically, may be installed in the end receiving cavity 221b-2 (see the attached Fig.52 ), the second push beam 531 ′ and the second guide sleeve 532 ′ can be slidably connected, one end of the connecting beam unit 533 ′ is hinged to the second push beam 531 ′, and the other end is hinged to the second lock body 52 ′.

[0284] With this structure, when the second push beam 531′ is driven to move upward, the hinged connecting beam unit 533′ can drive the second lock body 52′ to slide in the direction away from the lock head 51′, and then the lock head 51′ can rotate and unlock by itself; and when the driving force disappears, relying on its own gravity, etc., the second push beam 531′ can automatically slide down along the second guide sleeve 532′, and drive the second lock body 52′ to slide in the direction close to the lock head 51′ through the connecting beam unit 533′ to support the support part 512′ again, and the lock head 51′ can rotate in the opposite direction to achieve automatic locking. Of course, the reverse driving force can also be provided by an external device to drive the second push beam 531′ to reset and lock.

[0285] Specifically, the second push beam 531' can be directly opposite to the first connection hole 221d at the end (refer to Fig.50 and Fig.51 ), so that the unlocking component (first unlocking portion 77) can pass through the first connecting hole 221d at the end and contact the second push beam 531', thereby applying an upward unlocking driving force to the second push beam 531'.

[0286] It should be pointed out that the embodiment of the present invention does not limit the source of the driving force applied to the second push beam 531′ when unlocking. A manual drive solution may be adopted. For example, an unlocking component such as an unlocking lever may be provided. When unlocking is required, the staff may manually operate the unlocking component to generate a driving force for the second push beam 531′. Alternatively, an automatic drive solution may be adopted. In this case, the power source may be a motor, a cylinder, an oil cylinder, etc. These power sources may be installed on the vehicle body or on ground equipment. The specific selection may be made according to actual conditions. A transmission mechanism may also be provided between the power source and the second push beam 531′ to transmit the driving force of the power source.

[0287] The beam section of the second push beam 531′ located above the second guide sleeve 532′ may also be provided with a second connecting sleeve 531a′. Fig.54 As shown, the second connecting sleeve 531a′ may specifically include a tube portion and a hinge portion. The tube portion can be installed on the upper portion of the second push beam 531′ by threaded connection, welding, interference fit, etc. The hinge portion may include two hinge plates arranged opposite to each other, and the aforementioned connecting beam unit 533′ may be hinged between the two hinge plates.

[0288] The second connecting sleeve 531a' and the second guide sleeve 532' can cooperate to serve as a limiter for the downward movement of the second push beam 531' to limit the maximum downward movement distance of the second push beam 531' and, at the same time, limit the displacement distance of the second lock body 52'.

[0289] In fact, the downward movement limit of the second push beam 531′ can also be achieved through the cooperation of the lock 51′ and the fourth limiting portion 55′. In this way, the above-mentioned second connecting sleeve 531a′ may not exist; or, the connecting end of the connecting beam unit 533′ and the second push beam 531′ can also be used for limiting. The connecting end and the second push beam 531′ are hinged, and the two are usually arranged at an angle during actual operation. Therefore, even if the second connecting sleeve 531a′ does not exist, the connecting end can also serve as a limiting component for the downward movement of the second push beam 531′.

[0290] Furthermore, a second elastic member 531b' may be included, one end of which may act on the second push beam 531'. In the unlocked state, the deformation of the second elastic member 531b' may increase to gather elastic force. In this way, when the driving force acting on the second push beam 531' disappears, the elastic force of the second elastic member 531b' may be released to cooperate with the gravity of the second push beam 531' to jointly drive the lock head 51' to reset and lock.

[0291] Specifically, the second elastic member 531b' can be a spring, which can be installed in the second push beam 531', and the lower end of the second push beam 531' can be provided with a second support member 531c', and the two ends of the spring can respectively abut against the second guide sleeve 532' and the second support member 531c'. Among them, the second push beam 531' can act as a spring column, which is conducive to preventing the radial movement of the spring during the expansion and contraction process, and has a positive effect on improving the stability of the structure and the reliability of power transmission; and with this structure, in the unlocked state, the second push beam 531' can move upward, and the second elastic member 531b' can be compressed, and when restoring the lock, the second push beam 531' can move downward, and the second elastic member 531b' can be released again.

[0292] In fact, in the locked state, the second elastic member 531b′ can also have a certain amount of pre-compression, that is, the second elastic member 531b′ can still provide a certain elastic force when locked, which has a positive effect on ensuring the stability of the locked state of the lock head 51′, and can avoid the automatic unlocking of the lock head 51′ when the rail vehicle passes through a curve.

[0293] To facilitate adjustment of the pre-compression amount, the second support member 531c′ may be a nut, so that the spacing between the second support member 531c′ and the second guide sleeve 532′ can be adjusted by changing the screwing position of the nut, thereby adjusting the pre-compression amount of the second elastic member 531b′ in the locked state.

[0294] In the unlocked state, the second elastic member 531b′ can actually be in a stretched state. At this time, the installation position of the second elastic member 531b′ can change. Specifically, it can be arranged between the second connecting sleeve 531a′ and the second guide sleeve 532′, and its two ends can be fixedly connected to the second connecting sleeve 531a′ and the second guide sleeve 532′ to transmit the pulling force.

[0295] The connecting beam unit 533′ can be a structure formed by combining multiple connecting beams. In an exemplary embodiment, the connecting beam unit 533′ can include a first locking connecting beam 533a′, a second locking connecting beam 533b′ and a transfer block 533c′. The transfer block 533c′ can be provided with a non-collinear fixed hinge point 533c-1′, a first hinge point 533c-2′ and a second hinge point 533c-3′. The fixed hinge point 533c-1′ can be fixedly set, specifically, it can be fixed to the end connecting hook 221. One end of the first locking connecting beam 533a′ can be hinged to the second push beam 531′, and the other end can be hinged to the first hinge point 533c-2′. One end of the second locking connecting beam 533b′ can be hinged to the second lock body 52′, and the other end can be hinged to the second hinge point 533c-3′.

[0296] Using this structure, Fig.50 , Fig.51 As shown, when the second push beam 531′ moves upward, it can drive the first locking beam 533a′ to move upward, and then the adapter block 533c′ can be driven to rotate clockwise around the fixed hinge point 533c-1′, and the adapter block 533c′ drives the second locking beam 533b′ and the second lock body 52′ to move to the left, and the lock head 51′ can be rotated counterclockwise to unlock the support part; and when the second push beam 531′ moves downward, it can drive the first locking beam 533a′ to move downward, and then the adapter block 533c′ can be driven to rotate counterclockwise, and the adapter block 533c′ drives the second locking beam 533b′ and the second lock body 52′ to move to the right, and the lock head 51′ can be rotated clockwise to re-lock the support part.

[0297] It should be pointed out that the above-mentioned description of the specific structure of the second locking drive beam assembly 53' is only a preferred scheme of the embodiment of the present invention, and cannot be used as a limitation on the implementation scope of the body of the sled provided by the present invention. Other forms of the second locking drive beam assembly 53' may also be adopted under the condition of satisfying the functions. For example, the second locking drive beam assembly 53' may be directly set as a beam capable of linear displacement.

[0298] Further, such as Figure 5As shown, the body 1 is further provided with a transverse stop mechanism 6. When the support 4 is reset from a position separated from the end chassis 2 to a position connected to the end chassis 2, the transverse stop mechanism can determine the reset position of the support 4 to ensure that the support 4 is accurately installed on the body 1.

[0299] Specifically, the transverse stop mechanism 6 can be installed on the end frame 2 and the joint frame 3. Since the installation structure is similar, the structure of the transverse stop mechanism 6 is described below only by taking the installation on the end frame 2 as an example. Similarly, the embodiment of the present invention also provides two structural forms of transverse stop mechanisms 6.

[0300] The structure of the first transverse stop mechanism 6 can be referred to Figure 59-65 , Fig.59 This is a structural diagram of the first transverse stop mechanism installed on the end connecting hook; Fig.60 It is a structural diagram of a specific implementation method of the first transverse stop mechanism; Fig.61 for Fig.60 Exploded view of; Fig.62 is a structural diagram of the support; Fig.63 This is the split structure diagram of the first coupling beam; Fig.64 It is a structural diagram of another specific implementation of the first transverse stop mechanism; Fig.65 for Fig.64 An exploded view of the connection structure between the first stop beam and the connection end.

[0301] like Figure 59-Figure 61 As shown, the first transverse stop mechanism 6 includes: a support 61, which is fixed to the end connecting hook 221, and can be fixed by welding or the like, and a through hole 611 is provided on the support 61; a first stop beam 62; a stop drive beam assembly 63, which is transmission-connected to the first stop beam 62; in the stop state, the first stop beam 62 can extend out of the through hole 611 to form a transverse stop for the supporting part 4, and in the release state, the stop drive beam assembly 63 can drive the first stop beam 62 to retract to release the stop for the supporting part 4.

[0302] With this structure, in the stopping state, the first stop beam 62 can extend from the through hole 611 to form a lateral stop for the support part 4, thereby ensuring the accurate resetting of the support part 4; and in the releasing state, the stop driving beam assembly 63 can act on the first stop beam 62 to retract it, thereby releasing the stop for the support part 4 so as not to affect the normal separation of the support part 4 and the end frame 2.

[0303] Furthermore, a third elastic member 64 may be included, and the third elastic member 64 may act on the first stop beam 62. During the unblocking process, the deformation of the third elastic member 64 will increase to gather elastic force. In this way, when the driving force acting on the stop driving beam assembly 63 disappears, the third elastic member 64 may be released to drive the first stop beam 62 to automatically return to the stop position, thereby improving the automation of the device.

[0304] Combination Fig.61 The first stop beam 62 may include a thick neck portion 621 and a thin neck portion 622, and a step surface 623 may be formed between the two. The third elastic member 64 may be a spring, which may be mounted on the thin neck portion 622 and may interact with the step surface 623. At this time, the thin neck portion 622 may also act as a spring column to guide the expansion and contraction of the spring, which may largely avoid radial movement of the spring during the expansion and contraction process, and has a positive effect on improving the stability and reliability of the transmission.

[0305] It should be pointed out that in addition to the solution of using a spring, the third elastic member 64 can also be an elastic element in other forms such as an elastic ball, an elastic block, a tension rope, etc., as long as it can meet the use effect.

[0306] The support 61 can also be provided with a stop limiter 65, and the two ends of the third elastic member 64 can respectively act on the stop limiter 65 and the step surface 623. In the scheme of the attached figure, the first stop beam 62 can use the thick neck 621 as a stop part to improve the strength of the stop part. When disengaging, the step surface 623 can generate a compressive force on the third elastic member 64 to increase the compression amount of the third elastic member 64. In this scheme, the third elastic member 64 is in contact with the stop limiter 65 and the step surface 623.

[0307] Moreover, the cross section of the thick neck 621 can be non-circular, and the through hole 611 can match the thick neck 621. Matching here means that the shapes and sizes of the two are roughly the same. In this way, when the thick neck 621 is inserted into the through hole 611, the two will not rotate relative to each other, which can improve the reliability of the stop positioning. Further, the stop surface of the thick neck 621 in contact with the support part 4 can be a plane, so that the contact area between the support part 4 and the stop surface can be larger, and the reliability of the stop can be improved to a greater extent.

[0308] In fact, during the disengagement process, the third elastic member 64 can also generate pulling force. At this time, the thin neck 622 of the first stop beam 62 can be used as a stop portion in contact with the support portion 4, and in this solution, both ends of the third elastic member 64 need to be connected to the stop limit member 65 and the step surface 623 so that pulling force can be generated during disengagement.

[0309] The structure of the stopper 65 is not limited here. During the specific implementation, those skilled in the art can set it according to actual needs as long as the above-mentioned effect can be achieved. Fig.61 In the scheme, the stopper 65 can be in the shape of a sleeve, which can be a round cylinder, a square cylinder or a special-shaped cylinder of other shapes. The sleeve can protect the spring to prevent rain, dust and the like from intervening and affecting the normal operation of the spring to a large extent; Fig.64 In the scheme, the stop limiter 65 can be plate-shaped or block-shaped, and can be connected to the support 61 through the stop upper cover 615. At this time, the spring is in a relatively open space, and the operator can directly observe it to facilitate the adjustment of the installation status of the spring.

[0310] Combination Fig.62 In fact, the embodiment of the present invention does not limit the structure of the support 61. Its structure is mainly to adapt to the connection with the end connecting hook 221. In specific implementation, technical personnel in this field can adjust the shape of the support 61 according to the end connecting hook 221. The support 61 needs to provide corresponding installation points, one of which is the aforementioned through hole 611. Another installation point is also shown in the figure - the installation hole 612, which can be used to install the brake pipe assembly of the saddlebag (not shown in the figure).

[0311] The stop drive beam assembly 63 may include a first connecting beam 631 that is hingedly arranged. One end of the first connecting beam 631 may be a first driving end 6311 for receiving an external driving force, and the other end may be a connecting end 6312. The first hinge shaft 633 of the first connecting beam 631 may be fixedly arranged, specifically, may be fixedly installed on the support 61 and located between the first driving end 6311 and the connecting end 6312. The connecting end 6312 may be transmission-connected to the first stop beam 62.

[0312] Here, the embodiment of the present invention does not limit the source of the driving force exerted on the stop drive beam assembly 63 when disengaging. It can adopt a manual driving solution. For example, a disengaging component such as a disengaging lever can be provided. When disengaging is required, the disengaging component can be manually operated by a staff member to generate a driving force for the first driving end 6311. Alternatively, an automatic driving solution can be adopted. In this case, the power source can be a motor, a cylinder, an oil cylinder, etc. These power sources can be installed on the vehicle body or on ground equipment. The specific selection can be made according to actual conditions. A transmission mechanism can also be provided between the power source and the first driving end 6311 to transmit the driving force of the power source.

[0313] In one approach, if Figure 59-Figure 61As shown, the stop driving beam assembly 63 may also include a second connecting beam 632, one end of which may be connected to the first stop beam 62 by threaded connection or welding, and the other end and the connecting end 6312, one of which may be provided with a second hinge shaft 634 and the other may be provided with a strip guide hole 631a-1, and the second hinge shaft 634 may be inserted into the strip guide hole 631a-1.

[0314] With such arrangement, through the cooperation between the second hinge shaft 634 and the strip guide hole 631a-1, the rotational movement of the connecting end 6312 can be converted into the linear movement of the second connecting beam 632, thereby driving the first stop beam 62 to extend or retract.

[0315] In the accompanying drawings, the above-mentioned strip-shaped guide hole 631a-1 can be set on the connecting end 6312, and the second hinge shaft 634 can be fixed on the second connecting beam 632. In this way, the size of the second connecting beam 632 can be relatively smaller and the structure can be more compact.

[0316] In specific practice, the spring may have a certain amount of pre-compression to ensure the reliability of the first stop beam 62 when it is in the stop position, and the adjustment of the above-mentioned pre-compression amount may be determined by the connection position between the second connecting beam 632 and the first stop beam 62 .

[0317] Based on the solution of fixing the second connecting beam 632 and the first stop beam 62 by threaded connection, a first anti-loosening member 624 can also be provided, and the first anti-loosening member 624 can also be connected to the first stop beam 62 and can be tightly pressed against the second connecting beam 632 to prevent the second connecting beam 632 from loosening. The first anti-loosening member 624 can specifically be an anti-loosening nut, and of course, it can also be an anti-loosening stop limiter in the form of a strip, a block, etc.

[0318] Furthermore, a stopper connecting plate 613 and a guard plate 614 may be included. One end of the stopper connecting plate 613 may be connected to the support 61, and the other end may be connected to the guard plate 614, so as to protect the stopper driving beam assembly 63. The aforementioned first hinge shaft 633 may be installed on the stopper connecting plate 613. The specific installation method may be welding, or it may be installed with the aid of a mounting plate 633a and bolts, as long as the first hinge shaft 633 can be reliably fixed. In fact, the stopper connecting plate 613 and the guard plate 614 may also be used as part of the support 61.

[0319] In another scheme, if Fig.64 , Fig.65As shown, the connecting end 6312 can be provided with a strip guide groove 631e, the first stop beam 62 can be inserted into the strip guide groove 631e, and the connecting end 6312 can be abutted against the locking piece 631f set on the first stop beam 62 to limit the connection position of the connecting end 6321 and the first stop beam 62.

[0320] With such arrangement, through the cooperation between the first stop beam 62 and the strip guide groove 631e, the rotational movement of the connecting end 6312 can also be converted into the linear movement of the first stop beam 62 to drive the first stop beam 62 to release or return to the stop.

[0321] In detail, the connecting end 6312 can be confined between the locking member 631f and the stop limit member 65. The adjustment of the pre-compression amount of the third elastic member 64 can be determined by the installation position of the locking member 631f on the first stop beam 62. A first gasket 631g can also be provided between the locking member 631f and the connecting end 6312 to reduce the wear at the connection between the two.

[0322] The connection method between the locking member 631f and the first stop beam 62 can be a threaded connection or welding, etc. When it is a threaded connection, it can also include a second anti-loosening member, which can be an anti-loosening nut, or a stop strip (not marked in the drawings), a stop block, etc., which is used to limit the installation position of the locking member 631f.

[0323] In comparison, both of the above-mentioned two schemes can realize the conversion of the rotational motion of the first connecting beam 631 into the linear motion of the first stop beam 62, and can realize the switching of the first stop beam 62 between the stop state and the release state. In specific applications, technical personnel in this field can make a choice according to actual needs.

[0324] Taking the first scheme mentioned above as an example, the first connecting beam 631 may include a long plate member 631a and a short plate member 631b arranged at intervals, the first hinge shaft 633 may be connected to both the long plate member 631a and the short plate member 631b, one end of the long plate member 631a forms the above-mentioned connecting end 6312, the above-mentioned strip guide hole 631a-1 may be arranged on the long plate member 631a, and a roller 631c may be connected between the other end of the long plate member 631a and the short plate member 631b. At this time, the long plate member 631a, the short plate member 631b and the roller 631c are combined to form the first driving end 6311.

[0325] When the external driving force acts on the roller 631c, the roller 631c can rotate, which can reduce the friction between the first driving end 6311 and the external driving device, and has a positive effect on reducing the wear of the first driving end 6311.

[0326] Combination Fig.63, and may also include a roller 631d, the roller 631d may include a rod 631d-1 and a head 631d-2, the radial dimension of the head 631d-2 may be larger than the rod 631d-1, the long plate 631a and the short plate 631b may be provided with a through hole 631b-1, and the through hole 631b-1 of one of the two located on the inner side may be a stepped hole. In the assembled state, at least part of the head 631d-2 may be hidden in the large-diameter hole section of the stepped hole, and the end of the rod 631d-1 away from the head 631d-2 may be locked with the locking nut 631d-3.

[0327] The "inside" here refers to the side close to the end connecting hook 221. With this design, the protruding length of the roller 631d on the inner side can be shorter, which can largely avoid the contact friction between the first driving end 6311 and the end connecting hook 221 when rotating.

[0328] In the above-mentioned schemes, the recovery stop of the first stop beam 62 mainly relies on the third elastic member 64 directly acting on the first stop beam 62. In fact, in addition to this scheme, the first stop beam 62 can also be driven to return to the stop state by the stop drive beam assembly 63. In other words, the unblocking and return stop of the first stop beam 62 can be completed by the stop drive beam assembly 63. This scheme can be achieved by setting an elastic member for the stop drive beam assembly 63.

[0329] In addition, a core of the above-mentioned transverse stop mechanism is the separation of the stop drive beam assembly 63 and the first stop beam 62. In the stop state, actually only the first stop beam 62 and the support 61 are subjected to force, and the stop drive beam assembly 63 involved in the driving is not subjected to force. This is a key point of the higher reliability of the above-mentioned transverse stop mechanism.

[0330] The structure of the second transverse stop mechanism 6 can be referred to Figures 66-71 , Fig.66 A diagram showing the relative positions of the second transverse stop mechanism, the end connecting hook and the support portion in the stop state; Fig.67 for Fig.66 A partial enlarged view of Fig.68 A diagram showing the relative positions of the second transverse stop mechanism, the end connecting hook and the support portion in the unlocked state; Fig.69 for Fig.68 A partial enlarged view of Fig.70 This is a structural diagram of the second transverse stop mechanism installed on the end connecting hook; Fig.71 for Fig.70 Exploded view of the .

[0331] like Fig.67 and Figure 69-Figure 71As shown, the transverse stop mechanism 6 includes: a second stop beam 61′ which is hingedly arranged, the two ends of the second stop beam 61′ are respectively a driving end 611′ and a stop end 612′, a hinge shaft 613′ of the second stop beam 61′ is located between the driving end 611′ and the stop end 612′, and the hinge shaft 613′ is fixed to the end connecting hook 221; a limiting beam 62′ which is fixed to the end connecting hook 221; in the stopping state, the limiting beam 62′ is laterally pressed against the outer side of the second stop beam 61′, and the second stop beam 61′ can form a transverse stop for the supporting portion 4; in the disengaging state, the driving end 611′ can be rotated under force to drive the stop end 612′ to release the stop for the supporting portion 4.

[0332] With the above structure, in the stopping state, the limiting beam 62′ can be pressed against the second stop beam 61′ in the transverse direction to provide a transverse supporting force for the second stop beam 61′, and then the second stop beam 61′ forms a transverse stop for the support part 4, thereby ensuring the accurate resetting of the support part 4; while in the releasing state, the driving end 611′ can be subjected to force and drive the entire second stop beam 61′ to rotate, thereby driving the stop end 612′ to rotate to release the stop, so as not to affect the normal separation of the support part 4 and the end frame 2.

[0333] More importantly, in the stopping state, when the support part 4 is reset and hits the second stop beam 61′, only the stop end 612′ and the limiting beam 62′ are subjected to force, and the driving end 611′ which is the moving part of the lateral stop mechanism is not subjected to force, which plays a key role in ensuring the reliability of the lateral stop mechanism.

[0334] It should be pointed out that the embodiment of the present invention does not limit the source of the driving force applied to the driving end 611′ when the gear is disengaged. A manual driving scheme may be adopted. For example, a disengaging component such as a disengaging lever may be provided. When the gear needs to be disengaged, the disengaging component may be manually operated by a staff member to generate a driving force for the driving end 611′. Alternatively, an automatic driving scheme may be adopted. In this case, the power source may be a motor, a cylinder, an oil cylinder, etc. These power sources may be installed on the vehicle body or on ground equipment. The specific selection may be made according to actual conditions. A transmission mechanism may also be provided between the power source and the driving end 611′ to transmit the driving force of the power source.

[0335] Furthermore, a first limiter 63' may be included, and the first limiter 63' is fixed to the end connecting hook 221. In the unlocked state, the second stop beam 61' may abut against the first limiter 63' to prevent the second stop beam 61' from rotating excessively.

[0336] Here, the embodiment of the present invention does not limit the shape of the first stopper 63', which can be plate-shaped, block-shaped, column-shaped, etc., and can be determined according to actual conditions; similarly, the embodiment of the present invention does not limit the number and installation position of the first stopper 63', as long as the above-mentioned effect can be achieved. In an exemplary solution of the present invention, the first stopper 63' can be formed by extending the end hook wall plate 221c of the end connecting hook 221, so that there is no need to specially set the first stopper 63', and the number of parts can be less.

[0337] In the unlocked state, that is, when the second stop beam 61' abuts against the first limiter 63', the center of gravity of the second stop beam 61' can deviate from the hinge shaft 613' in the longitudinal direction and be located on the side where the stop end 612' is located. In this way, when the driving force acting on the driving end 611' disappears, the second stop beam 61' can automatically rotate to the stop state under the action of its own gravity, without the need to set up other driving components, and the structure of the device can be relatively simple.

[0338] And / or, a fourth stop elastic member 65' may be included, which may act on the second stop beam 61'. During the unblocking process, the deformation of the fourth stop elastic member 65' may increase to gather elastic force. In this way, when the driving force acting on the driving end 611' disappears, the elastic force gathered by the fourth stop elastic member 65' may be released to drive the second stop beam 61' to rotate to the stop state alone or in cooperation with the aforementioned gravity.

[0339] The above-mentioned fourth elastic stop member 65′ can specifically be a torsion spring, which can be installed in a sleeve on the hinge shaft 613′. Among the two protruding ends of the torsion spring, one protruding end can be fixed (or abutted against a fixed component, such as the end connecting hook 221), and the other protruding end can abut against the second stop beam 61′. When the second stop beam 61′ is rotated to release the stopping state, the torsion spring can gather the torsional deformation force, and when the driving force acting on the driving end 611′ disappears, the above-mentioned torsional deformation force can be released to drive the second stop beam 61′ to rotate automatically.

[0340] The fourth elastic stopper 65' may also be a linear spring, such as a tension spring, a compression spring, or other spring element that generates elastic force by axial displacement. Fig.69 Taking the solution in as an example, the linear spring can be a tension spring, one end of which can be fixed, and the other end can be connected to the second stop beam 61', so that the elastic force can be gathered when the second stop beam 61' rotates to release the stop.

[0341] In addition to the above-mentioned torsion spring and linear spring, the fourth elastic stopper 65' may also be an elastic element in the form of an elastic block, an elastic ball, a tension rope, etc., as long as the above-mentioned technical effect can be achieved.

[0342] Furthermore, a second stopper 64' may be included, and the second stopper 64' is fixed to the end connecting hook 221. In the stopping state, the second stopper beam 61' may abut against the second stopper 64' to limit the position of the second stopper beam 61' in the stopping state. The structure, quantity and installation position of the second stopper 64' may be similar to those of the first stopper 63', and a repeated description is not given here.

[0343] Moreover, through the support of the above-mentioned second limiting member 64′, the second stop beam 61′ can be set with a gap between it and the limiting beam 62′ in the vertical direction. In this way, the limiting beam 62′ does not need to bear the gravity of the second stop beam 61′. Accordingly, no shear stress will be generated at the connection between the limiting beam 62′ and the end connecting hook 221, and the connection reliability between the limiting beam 62′ and the end connecting hook 221 can be higher.

[0344] With respect to the transverse stop mechanism 6 of the support portion 4 involved in the above-mentioned embodiments, the structure of the second stop beam 61 ′ will be described in the following embodiments of the present invention.

[0345] Combination Fig.67 In the stop state, the driving end 611′ can be an end that is gradually inclined from top to bottom toward the stop end 612′. In this way, when the driving end 611′ is acted upon by an upward driving force, the second stop beam 61′ will naturally rotate in the direction of releasing the stop state to ensure that the second stop beam 61′ can be unlocked smoothly.

[0346] It can be understood that adjusting the shape of the driving end portion 611 ′ is actually adjusting the driving force and the direction of action of the driving end portion 611 ′. Thus, in a specific implementation, the rotational unlocking of the second stop beam 61 ′ can also be achieved by adjusting the direction of the driving force.

[0347] In addition, in the stopping state, the end of the second stop beam 61′ away from the driving end 611′ can be provided with a downwardly bent elbow, which can serve as the above-mentioned stop end 612′. The setting of the elbow can improve the strength of the stop end 612′ and at the same time, it can also avoid the vehicle body and brake pipe protection device (not shown in the figure).

[0348] Recombination Fig.71The hinge shaft 613′ of the second stop beam 61′ can be a stepped shaft, which can specifically include a large diameter section 613a′ and a small diameter section 613b′, wherein the large diameter section 613a′ can be used to connect with the end connection hook 221, and the second stop beam 61′ can be installed on the large diameter section 613a′; it can also include a third stopper 613c′, which can specifically be a nut, which can be installed on the small diameter section 613b′ to cooperate with the end connection hook 221 to limit the installation position of the second stop beam 61′. It should be understood that the function of the third stopper 613c′ is mainly to limit, not to lock, and after the installation is completed, it is necessary to ensure that the second stop beam 61′ can rotate smoothly.

[0349] A second gasket 613d′ may be provided between the third limit member 613c′ and the second stop beam 61′. The second gasket 613d′ may be made of rubber or metal, etc., to avoid direct friction between the second stop beam 61′ and the third limit member 613c′, which has a positive effect on reducing wear.

[0350] Brake pipe guard 10

[0351] The brake pipe is an important component of a railway vehicle and needs to pass through the vehicle body in the longitudinal direction during installation. For a saddleback vehicle, since the support part 4 and the main body part 1 are repeatedly separated and installed, the brake pipe may interfere with the separation and installation of the support part. Once interference occurs, the brake pipe may be damaged by the support part 4 in motion.

[0352] To this end, the present application also relates to a flip-up brake pipe protection device, which includes a protective shell and a brake pipe installed on the protective shell. When the support part rises to prepare for separation from the main body, the protective shell can be turned outward laterally in the vertical plane to avoid interference with the support part 4. When the support part 4 falls to be installed on the main body 1, the protective shell can be turned inward laterally to return to its original position. In this way, the brake pipe can be better prevented from interfering with the support part 4 in motion. At the same time, the protective shell can also protect the brake pipe, which can prevent the brake pipe from contacting the ground and causing wear and leakage, which has a positive effect on the driving safety of the piggyback vehicle.

[0353] For more information, see Figure 72-85 , Fig.72 It is a structural diagram of the brake pipe protection device; Fig.73 for Fig.72 Enlarged view of point C in the middle; Fig.74 for Fig.72 The enlarged view of point D in the middle; Fig.75 for Fig.72 Enlarged view of point E in the middle; Fig.76 It is a structural diagram of the brake pipe protection device in a state where the support part and the main body part are connected; Fig.77 for Fig.76 A magnified view of the part within the middle circle; Fig.78 It is a structural diagram of the brake pipe protection device in a state where the support part and the main body part are separated; Fig.79 for Fig.78 A magnified view of the part within the middle circle; Fig.80 A structural diagram showing a first protective stopper and a second protective stopper provided on a support; Fig.81 is a structural diagram of the first pivot plate; Fig.82 is a structural diagram of the second pivot plate; Fig.83 This is a structural diagram of the protective partition; Fig.84 This is the structural diagram of the pipe hanger seat plate; Fig.85 This is the structural diagram of the pipe hanging connecting plate.

[0354] like Fig.76 As shown, the body of the saddleback vehicle generally includes a main body 1 and a support 4, and the support 4 can be translated laterally to be separated from the chassis. The brake pipe is arranged on the lateral outer side of the support 4. When the support 4 is translated laterally, in order to avoid the interference of the brake pipe, the support 44 needs to be lifted upward for a distance. In order to shorten the lifting distance and protect the brake pipe, the present invention designs a brake pipe protection device.

[0355] like Fig.72 As shown, the brake pipe protection device 10 includes a protection shell 11, and the shell cavity of the protection shell 11 is used to accommodate the brake pipe. The protection shell 11 can protect the brake pipe on the one hand, and facilitate the unified movement of the brake pipe on the other hand. Fig.76 As shown, when the support portion 4 is connected to the main body 1 , the protective shell 11 is located laterally outside the side wall 42 of the support portion 4 .

[0356] like Fig.72 As shown, the brake pipe protection device 10 also includes a protection connecting member 12, such as Fig.69 As shown, the protective connector 12 includes a protective inner end 12a, a protective outer end 12b, and a protective transition portion 12c located therebetween. Fig.77 As shown, the protective inner end portion 12a is located at the lower side of the support portion 4 and abuts against the support portion 4, specifically, it can abut against the pressure plate 412d of the support portion 4; the protective outer end portion 12b is located laterally outside the protective inner end portion 12a, and is rotatably connected to the main body portion 1, specifically, it can be rotatably connected to the support 61 of the main body portion 1.

[0357] like Fig.77As shown, during the connection process between the support part 4 and the main body 1, the pressure of the support part 4 on the protective inner end 12a gradually increases, so that the force on the protective inner end 12a gradually becomes greater than the gravity of the protective outer end 12b. At this time, the protective connecting member 12 rotates around the rotational connection position with the main body 1 (as shown in the direction of the arrow in the figure), thereby driving the protective shell 11 to rotate upward and inward, so that the protective shell 11 is reset and finally reaches Fig.77 Position shown.

[0358] like Fig.79 As shown, during the separation process of the support portion 4 and the main body 1, the pressure of the support portion 4 on the protective inner end portion 12a gradually decreases, so that the force on the protective inner end portion 12a gradually becomes smaller than the gravity of the protective outer end portion 12b. At this time, the protective connecting member 12 rotates around the rotation connection position with the main body 1 under the action of gravity (as shown in the direction of the arrow in the figure), thereby driving the protective shell 11 to rotate downward and outward, so that the height position of the protective shell 11 decreases, and finally reaches Fig.79 Here, when the brake pipe guard 10 is installed, its center of gravity position can be adjusted so that its center of gravity can be distributed laterally outside the rotation center, so that once the connection between the brake pipe guard 10 and the support 4 is released, the above-mentioned rotation can be generated.

[0359] Since the height position of the protective shell 11 is lowered, the support part 4 only needs to be lifted upward for a short distance to avoid the interference of the protective shell 11 on the support part 4, so that the support part 4 can smoothly perform lateral translation.

[0360] In summary, during the separation of the support part 4 from the main body 1, the protective shell 11 can automatically rotate downward and outward to avoid the support part 4, effectively shortening the lifting distance of the support part 4; during the connection of the support part 4 to the main body 1, the protective shell 11 can automatically reset. The shortening of the lifting distance and the automatic avoidance and automatic reset of the protective shell 11 improve the separation efficiency and connection efficiency of the support part 4 and the main body 1.

[0361] Furthermore, the brake protection device 10 may also be provided with a first protection limiter 13 (see Fig.77 and Fig.80 ), the first protective stopper 13 is fixed to the main body 1, specifically, it can be fixed on the support 61, when the protective shell 11 rotates downward and outward to the limit position, the protective connecting member 12 conflicts with the first protective stopper 13, so that the risk of the protective shell 11 being difficult to reset due to excessive downward rotation can be prevented. In the figure, the first protective stopper 13 is a block, and in actual implementation, its structure and shape can be adjusted as needed and are not limited to a block.

[0362] Furthermore, the brake pipe protection device 10 may also be provided with a magnetic member 14 (see Fig.72), when the protective shell 11 is located on the lateral outer side of the support 4, the protective shell 11 is magnetically attracted to the side wall 42 of the support 4 through the magnetic member 14. This can alleviate the vibration of the brake protection device with the vehicle, which is conducive to improving the service life of the brake protection device 10.

[0363] In the illustrated solution, the magnetic member 14 is detachably fixed to the upper surface of the protective housing 11, and can be fixed by bolts and nuts. Fixing the magnetic member 14 to the upper surface of the protective housing 11 can ensure that the direction of the magnetic force on the protective housing 11 during the resetting process of the protective housing 11 is substantially consistent with the resetting direction of the protective housing 11, so that the magnetic force can assist the resetting of the protective housing 11. The magnetic member 14 is detachably fixed to the protective housing 11, which facilitates the replacement of the magnetic member 14.

[0364] Furthermore, the brake pipe protection device 10 may also be provided with a second protection stopper 15 (see Fig.79 and Fig.80 ), when the protective shell 11 is reset to the lateral outer side of the support 4, the protective connector 12 conflicts with the second protective stopper 15. When the magnetic member 14 is provided, when the support 4 moves upward, under the action of the magnetic force, the protective connector 12 tends to move upward with it. By providing the second protective stopper 15, the protective connector 12 can be prevented from moving upward with the support 4. In the figure, the second protective stopper 15 is a block. In actual implementation, its structure and shape can be adjusted as needed and are not limited to a block.

[0365] In the illustrated scheme (see Fig.73 ), the protective connecting member 12 includes a first pivot plate 121, a second pivot plate 122 and a pivot shaft 123. The first pivot plate 121 and the second pivot plate 122 are arranged at intervals along the longitudinal direction. Fig.77 As described above, the second pivot plate 122 is closer to the support portion 4 than the first pivot plate 121. The support 61 is located between the first pivot plate 121 and the second pivot plate 122, and the pivot shaft 123 passes through the first pivot plate 121, the mounting hole 612 on the support 61, and the second pivot plate 122 in sequence, connecting the three together, thereby realizing the rotation connection between the protective connector 12 and the main body 1. This structure has high connection reliability, and of course, it is not limited to this structure in actual implementation.

[0366] In the illustrated scheme, a limit head (not visible in the figure) is provided at one end of the pivot shaft 123, and a radial hole is provided at the other end, and a limit pin 1231 passes through the radial hole. The first pivot plate 121 and the second pivot plate 122 are located between the limit head and the limit pin 1231, so that the pivot shaft 123 can be axially limited, and the connection reliability of the protective connecting member 12 and the main body 1 can be further improved.

[0367] In the illustrated embodiment, the protection connecting member 12 further includes a protection roller 125, and the protection roller 125 is rotatably connected to the second pivot plate 122. Fig.77 As shown, the second pivot plate 122 extends to the lower side of the pressing plate 412d, so that the outer peripheral surface of the protection roller 125 abuts against the lower surface of the pressing plate 412d, thereby achieving the abutment of the protection connecting member 12 and the support portion 4. By providing the protection roller 125, the wear of the protection connecting member 12 and the support portion 4 during the abutment process can be alleviated.

[0368] In the illustrated scheme (see Fig.73 ), a fixed shaft 124 is provided, one end of the fixed shaft 124 is fixed to the second pivot plate 122, specifically, it can be fixed by welding, and the other end of the fixed shaft 124 is fixed with a retaining ring (not shown in the figure), and the protective roller 125 can be rotatably sleeved on the outer periphery of the fixed shaft 124 and is located between the retaining ring and the second pivot plate 122, and the retaining ring and the second pivot plate 122 can prevent the protective roller 125 from separating from the fixed shaft 124.

[0369] In the illustrated scheme (see Fig.72 and Fig.73 ), the front and rear ends of the protective housing 11 are not provided with end plates, and the front and rear ends of the protective housing 11 are blocked by the protective connector 12, which is conducive to the lightweight of the brake pipe protective device 10. In detail, the front end of the protective housing 11 is blocked by a first pivot plate 121 and a second pivot plate 122, and the rear end is blocked by another first pivot plate 121 and another second pivot plate 122. The first pivot plate 121 and the second pivot plate 122 are both provided with a protective through hole 12d for the brake pipe to pass through. Fig.81 and Fig.82 ), two protective vias 12d are respectively provided on the first pivot plate 121 and the second pivot plate 122, and the two protective vias 12d are staggered in the vertical direction. In actual implementation, the number and arrangement of the protective vias 12d are not limited thereto.

[0370] In the illustrated scheme (see Fig.72 ), the protective shell 11 includes a C-shaped protective beam 111, a plurality of protective sealing plates 112 and a plurality of pipe hanging assemblies 113. Each protective sealing plate 112 is fixed to the opening side of the C-shaped beam, and can be welded and fixed. Each protective sealing plate 112 is spaced apart from each other along the length direction (i.e., longitudinal direction) of the C-shaped protective beam 111, so that an installation opening is formed between adjacent protective sealing plates 112, and the installation opening is used to install the pipe hanging assembly 113.

[0371] Specifically, Fig.74 and Fig.75As shown, each set of pipe hanging assembly 113 includes two protective baffles 1131 and two pipe hanging seat plates 1132. The two protective baffles 1131 are fixed inside the C-shaped protective beam 111, and can be fixed by welding. The two protective baffles 1131 are spaced apart from each other along the length direction (i.e., longitudinal direction) of the C-shaped protective beam 111. The two pipe hanging seat plates 1132 are fixed to the two protective baffles 1131 in a one-to-one correspondence and are located between the two protective baffles 1131. In addition, Fig.75 A pipe hanging connecting plate 1133 is also provided.

[0372] Specifically, Fig.83 As shown, the protective baffle 1131 is provided with a pipe hole for the brake pipe to pass through. The brake pipe passes through the pipe holes on each protective baffle 1131 in turn. In this way, the shaking of the brake pipe in the protective shell 11 can be reduced, which is beneficial to improving the protection effect and alleviating driving vibration.

[0373] Specifically, Fig.84 As shown, the pipe hanger seat plate 1132 is provided with a seat hole for threaded fasteners to pass through. Fig.85 As shown, the pipe hanging connecting plate 1133 is provided with connecting holes for threaded fasteners to pass through. Fig.74 In the embodiment, the seat holes of the two pipe hanger base plates 1132 are aligned so that the threaded fasteners pass through the two pipe hanger base plates 1132 in sequence. Fig.75 In the embodiment, the connection hole of the pipe hanger connection plate 1133 is aligned with the seat hole of the pipe hanger seat plate 1132 so that the threaded fastener passes through the pipe hanger connection plate 1133 and the pipe hanger seat plate 1132 in sequence.

[0374] In the illustrated scheme (see Fig.72 ), there are three sets of pipe hanging assemblies 113, and the structures of the pipe hanging assemblies 113 on both sides are the same ( Fig.74 As shown in the structure, the middle pipe hanging assembly is provided with one more pipe hanging connecting plate 1133 than the pipe hanging assemblies on both sides.

[0375] The part of the brake pipe 20 located inside the protective housing 11 is a rigid pipe, and the pipe section located outside the protective housing 11 is a flexible pipe. The two ends of the rigid pipe are respectively connected to the two flexible pipes. One end of the flexible pipe connected to the rigid pipe is provided with a flange joint 201, and the flexible pipe is fixed to the brake pipe protective device 10 through the flange joint 201. In a specific solution, the first pivot plate 121 is provided with a flange connection hole, and the flange joint 201 is fixed on the first pivot plate 121 (see Fig.77 ). This brake pipe can adapt to the frequent flipping of the protective shell 11, is not easy to break, and has high reliability.

[0376] Specifically, the rigid pipe can be a whole pipe section, or multiple rigid pipe sections connected by flanges or quick-release joints. Each flexible pipe can be a whole pipe section, or multiple flexible pipe sections connected by flanges or quick-release joints.

[0377] The following embodiments of the present invention will respectively describe the structures of different components of the station field equipment provided by the present invention.

[0378] Base frame lifting part

[0379] refer to Figures 86-93 , Fig.86 It is a schematic diagram of the structure of the underframe lifting device in the highest position; Fig.87 yes Fig.86 perspective drawing; Fig.88 is a perspective view of the undercarriage lifting device in the lowest position; Fig.89 is a schematic diagram of the structure of the first base; Fig.90 It is a structural schematic diagram of the support seat; Fig.91 It is a schematic diagram of the structure of the push rod; Fig.92 It is a structural diagram of the joystick; Fig.93 It is a schematic diagram of the structure of the first support rod.

[0380] Each group of the undercarriage lifting parts includes two undercarriage lifting devices 7 respectively located on both sides of the track 100, that is, there are four undercarriage lifting devices 7 in total, and undercarriage lifting devices 7 are respectively arranged on both sides of a undercarriage to lift the undercarriage from both sides. In this way, the lifting stability can be guaranteed and the strength requirement of a single undercarriage lifting device 7 can be reduced.

[0381] Specifically, in this embodiment, Figures 86-88 As shown, the chassis lifting device 7 includes a first base 71, a first support base 72 and a driving mechanism, wherein both sides of the first support base 72 are connected to the first base 71 through a first supporting assembly 74. Specifically, the first base 71 is provided with a first slideway 711, the first support base 72 is provided with a second slideway 721, and the first supporting assembly 74 includes a first supporting rod 741 and a second supporting rod 742 arranged crosswise, wherein the top end of the first supporting rod 741 is hinged to the first support base 72, the bottom end of the first supporting rod 741 can slide along the first slideway 711, the bottom end of the second supporting rod 742 is hinged to the first base 71, and the top end of the second supporting rod 742 can slide along the second slideway 721, and the driving mechanism can act on the first supporting assembly 74 to change the angle between the first supporting rod 741 and the second supporting rod 742, thereby changing the height of the first supporting base 72 from the first base 71.

[0382] Among them, the support seat 72 abuts against the lower end surface of one end of the chassis toward the supporting part 4. When the driving mechanism acts on the supporting assembly 74 to reduce the angle between the first support rod 741 and the second support rod 742, the height of the supporting assembly 74 increases, thereby driving the support seat 72 to rise relative to the first base 71, and then lifting the chassis of the saddlebag vehicle toward one end of the supporting part 4 until the center plate of the bogie is no longer under force, and the lifting operation of the supporting part 4 can be carried out. At this time, since the chassis lifting device 7 can provide support for the chassis so that it will not be deflected, and after the supporting part 4 is loaded and unloaded and matched with the chassis again, the driving mechanism acts on the supporting assembly 74 to increase the angle between the first support rod 741 and the second support rod 742, so that the height of the supporting assembly 74 decreases, thereby driving the support seat 72 to descend to its original position relative to the first base 71.

[0383] In detail, when the saddlebag vehicle arrives at the loading and unloading station, the parking position of the saddlebag vehicle is accurately located, and a chassis lifting device 7 (four in total) is respectively provided on the left and right sides below the chassis at the front and rear ends of the supporting part 4. The function of each chassis lifting device 7 is to drive the supporting part 4 upward toward one end of the supporting part 4 by the front and rear chassis until the bogie center plate is no longer under force. The chassis lifting device 7 keeps its position stable, and then acts on the supporting part 4 through the supporting part lifting device 8 to make it rise and separate from the chassis, and through the action of the translation device, the supporting part 4 is translated to the outside of the track 100 to the loading and unloading station for easy loading and unloading.

[0384] The driving mechanism includes a driving member 731 and a locking assembly 732. The driving member 731 is arranged on the first base 71 and provides a power source, which acts on the support assembly 74 to change the angle between the two support rods (the first support rod 741 and the second support rod 742). When the angle between the first support rod 741 and the second support rod 742 reaches the minimum, that is, when the support seat 72 rises to the highest position, the locking assembly 732 can lock the relative positions of the two support rods, that is, keep the state of the support assembly 74 unchanged, so that the height position of the support seat 72 is stable, and the support seat 72 is prevented from falling due to sudden failure of the driving member 731, thereby ensuring that the chassis lifting device 7 can provide stable support for the chassis when in use.

[0385] Furthermore, the locking assembly 732 includes a push rod 733 and a rocker arm 734, and the first base 71 is also provided with a pin seat 712. Specifically, the push rod 733 includes a first section 7331, a bend 7333 and a second section 7332 which are arranged in sequence, wherein the end of the first section 7331 is hinged to the bottom end of the first support rod 741 and can slide along the first slide 711, the bend 7333 is hinged to the driving member 731, one end of the rocker arm 734 is hinged to the end of the second section 7332, and the other end of the rocker arm 734 is hinged to the pin seat 712; the driving member 731 can act on the bend 7333 to make the rocker arm 734 rotate around the pin seat 712, and drive the bottom end of the first support rod 741 to slide along the first slide 711, and when the angle between the two reaches the minimum, the bend 7333 is just located above the pin seat 712.

[0386] In detail, the opening of the bend 7333 is downward, the rocker arm 734 is hinged between the second section 7332 and the pin seat 712, the driving member 731 can act on the bend 7333, and drive the rocker arm 734 to rotate around the hinge point between it and the pin seat 712, thereby driving the push rod 733 to rotate around the hinge point between the bend 7333 and the driving member 731, and when the first section 7331 rotates around the hinge point, it can drive the first support rod 741 to move. Due to the limitation of the first slide 711, the bottom end of the first support rod 741 can only slide along the first slide 711 to achieve a change in the angle between the two support rods.

[0387] like Fig.87 When the first support rod 741 slides along the first slide 711 to the minimum angle between the two support rods so that the support seat 72 rises to the highest position, the bend 7333 is just located above the pin seat 712, and the driving member 731 no longer works. At this time, if the driving member 731 fails and its thrust is insufficient, the driving action of the driving member 731 on the support assembly 74 is removed, while the chassis continues to press the support seat 72 downward, and the angle between the two support rods tends to increase. Since the opening of the bend 7333 is downward and located directly above the pin seat 712, at this time, the vertical downward pressure cannot move the push rod 733 laterally, thereby limiting the rotation of the rocker arm 734 and the sliding of the first support rod 741 along the first slide 711, thereby maintaining the state of each support assembly 74 unchanged, that is, the angle between the two support rods remains unchanged, the height of the support seat 72 remains unchanged, and the stability is better.

[0388] By setting the locking device mentioned above, when the driving member 731 raises the support seat 72 to the highest position through the support assembly 74, the support assemblies 74 can be automatically locked. In this state, the vertical force cannot change the state of the support assemblies 74. Only when the base frame needs to be lowered, the driving member 731 provides a reverse force to make the push rod 733 move horizontally until the bend 7333 is separated from the pin seat 712, so as to achieve unlocking and drive the bottom end of the first support rod 741 to move in the opposite direction along the first slide 711 until the support seat 72 is lowered to the lowest state (such as Fig.88 The locking assembly 732 can achieve locking and unlocking while achieving the lifting and lowering of the support seat 72, without the need for additional locking components, which can simplify the overall structure and operation, and ensure the stability of the overall structure and the convenience of operation.

[0389] Specifically, Figures 86-88 As shown, in this embodiment, the driving member 731 is a first hydraulic cylinder, the first piston rod of the first hydraulic cylinder is hinged with the bend 7333 of the push rod 733, the two sides of the support seat 72 are respectively connected through the support assembly 74 and the first base 71, and the first hydraulic cylinder and the bottom end of the first support rod 741 of one of the support assemblies 74 can realize the overall lifting of all the support assemblies 74, and the stability is good. Of course, in this embodiment, the power source can also be provided by a motor, a gear and a rack, or a motor, a screw and a nut, and no specific limitation is made here.

[0390] In the above embodiment, a connecting shaft is further provided at the end of the first section 7331 of the push rod 733, and the connecting shaft sleeve is provided with a first roller 7335. When the driving member 731 acts on the bend 7333 to rotate the push rod 733 around the hinge point between the bend 7333 and the driving member 731, the end of the first section 7331 slides along the first slideway 711, and at this time, the first roller 7335 can roll along the bottom plate 71. The end of the first section 7331 of the push rod 733 can contact the first base 71 through the first roller 7335, so that when the end of the first section 7331 slides along the first slideway 711, the first roller 7335 rolls along the first base 71, which reduces resistance and also reduces friction and wear between the first section 7331 and the first base 71, thereby ensuring service life. Specifically, the push rod 733 can be as follows: Fig.91 As shown, it includes two V-shaped connecting members 7334 arranged in parallel, and a connecting shaft is provided between the ends of the two V-shaped connecting members 7334 facing the first section 7331. Alternatively, a groove can be provided at the end of the first section 7331, and the connecting shaft is provided between the two side walls of the groove.

[0391] Further, such as Fig.89As shown, the first base 71 is also provided with a rolling plate 713, and the first roller 7335 can roll along the rolling plate 713. Alternatively, in this embodiment, the first roller 7335 can also be arranged to roll directly along the upper surface of the first base 71, and the arrangement of the rolling plate 713 allows it to be replaced after it is worn, thereby ensuring the service life of the first base 71.

[0392] In the above embodiment, if Fig.92 As shown, a concave notch 7341 is provided at one end of the rocker 734 facing the pin seat 712, and shaft holes 7342 are respectively provided on both side walls of the concave notch 7341 and the pin seat 712, and the pin seat 712 is disposed in the concave notch 7341 and rotatably connected via a pin shaft passing through the shaft hole 7342. Alternatively, in this embodiment, one end of the rocker 734 can also be disposed at one side of the pin seat 712 and connected via a pin shaft, while the rocker 734 is provided with the concave notch 7341 and the pin seat 712 is located in the concave notch 7341, so that the connection between the two can be more stable and avoid the occurrence of deflection and jamming.

[0393] In the above embodiment, the chassis lifting device 7 further includes an upper sliding shaft 75 and a roller sleeve 751 sleeved on the upper sliding shaft 75. The two sides of the support seat 72 are connected to the first base 71 through symmetrically arranged support assemblies 74. The upper sliding shaft 75 passes through the top of the second support rod 742 of the symmetrically arranged support assembly 74 and can slide along the second slideway 721. The roller sleeve 751 is located between the two second support rods 742 and rolls against the support seat 72. In other words, the support assembly 74 and the support seat 72 are acted on by the roller sleeve 751 to ensure the supporting force between the support assembly 74 and the support seat 72, and the stability is good. At the same time, the roller sleeve 751 is arranged between the two second support rods 742, and can also limit the two to avoid the change of the distance between the two to affect the lifting of the chassis.

[0394] Furthermore, the chassis lifting device 7 further includes a lower sliding shaft 76, which passes through the bottom end of the first support rod 741 of the symmetrically arranged support assembly 74 and the first section 7331 of the push rod 733, and can slide along the first slideway 711. The arrangement of the lower sliding shaft 76 enables the bottom end of the first support rod 741 to slide along the first slideway 711, and the bottom end of the first support rod 741 is hinged to the end of the first section 7331 of the push rod 733, which can simplify the overall structure.

[0395] Furthermore, both sides of the bottom end of the first support rod 741 are respectively provided with reinforcement sleeves 7411 sleeved outside the lower sliding shaft 76. The provision of the reinforcement sleeve 7411 can increase the structural strength of the bottom end of the first support rod 741, and can also limit the bottom end of the first support rod 741, reduce the distance between the two sides thereof and the first base 71 and the first end of the push rod 733, avoid deflection, and have good stability.

[0396] In the above embodiment, the first base 71 and the support base 72 are respectively provided with side panels, and the first slideway 711 and the second slideway 721 are both long holes provided on the side panels. Alternatively, in this embodiment, the first slideway 711 and the second slideway 721 can also be provided as a slide rail or a slide groove structure, and the long hole structure is relatively simple, which can simplify the manufacturing process.

[0397] In the above embodiment, if Fig.90 As shown, the chassis lifting device 7 further includes a first unlocking portion 77, which is disposed on the upper end surface of the support seat 72 and is used to unlock the aforementioned locking mechanism 5. Specifically, taking the aforementioned first middle locking mechanism 5 as an example, when unlocking, the first unlocking portion 77 can move upward with the chassis lifting device 7, and pass through the first connecting hole 221d to interact with the first push beam 541, thereby driving the first lock body 51 to rotate, thereby releasing the lock on the supporting portion 4. With such a configuration, when the chassis is lifted, the locking mechanism 5 can be automatically unlocked, and the degree of automation is higher.

[0398] The underframe lifting device 7 disposed on the side of the track 100 facing the loading and unloading station is provided with a second unlocking portion 78, such as Fig.90a As shown, the second unlocking portion 78 can unlock the lateral stop mechanism 6 on the corresponding side when the chassis lifting device 7 lifts the chassis. Taking the second lateral stop mechanism 6 as an example, when the chassis lifting device 7 lifts the chassis, the second unlocking portion 78 moves upward and can interact with the driving end portion 611' of the second stop beam 61' to drive the second stop beam 61' to rotate around the hinge shaft 613', thereby releasing the lateral stop for the support portion 4.

[0399] With such arrangement, when the chassis is lifted, the lateral stop mechanism 6 can be automatically unlocked, and in conjunction with the unlocking of the locking mechanism 5 by the aforementioned first unlocking portion 77, under the action of the chassis lifting device 7, not only the lifting of the chassis can be achieved, but also the locking mechanism 5 and the lateral stop mechanism 6 can be unlocked synchronously. That is to say, after the chassis is lifted, the supporting portion 4 is ready to be lifted and separated, and the translational separation operation of the supporting portion 4 can be faster, which has a positive effect on improving the efficiency of loading and unloading.

[0400] In addition, for one main body 1, there are actually four transverse stop mechanisms 6, which can be respectively arranged on the transverse sides of the two chassis (i.e., on the two sides of the track 100) to limit the transverse sides of the longitudinal end portions of the support portion 4. When realizing the translational separation of the support portion 4, it is actually only necessary to unlock the two transverse stop mechanisms 6 on the same side of the track 100. Therefore, the second unlocking part 78 is provided on the chassis lifting device 7 on the side of the track 100 facing the loading and unloading station to realize the translational separation of the support portion 4 relative to the chassis. If loading and unloading stations are provided on both sides of the track 100, each chassis lifting device 78 can be provided with a second unlocking part, so as to facilitate the flexibility of loading and unloading.

[0401] Lifting part

[0402] In the above embodiment, if Figure 3 and Figure 4 As shown, the support lifting part includes two hydraulic lifting devices 8 respectively located on both sides of the track 100. That is to say, there are four hydraulic lifting devices 8 in total, and two hydraulic lifting devices arranged at intervals are arranged below one end of the support 4 to act on it and make it rise and fall. Such an arrangement can make the overall structure simple and stable.

[0403] Of course, in the present embodiment, there is no limitation on the specific structure of the supporting lifting part and the side platform lifting part 200, and the side platform lifting part 200 may also be configured as a hydraulic lifting device 8, or the supporting lifting part and the side platform lifting part 200 may also be configured as a structure that is the same as or similar to the structure of the underframe lifting device 7, such as a structure including a driving part, cross-arranged support rods, and a support seat.

[0404] Furthermore, the lower end surface of the supporting part 4 is provided with a third positioning part, and the top end of the hydraulic lifting device 8 is provided with a fourth positioning part adapted to the third positioning part, so as to ensure that the hydraulic lifting device 8 is in the process of lifting the supporting part 4, the two functions are stable, and accurate positioning can be achieved. In this embodiment, the structure of the third positioning part and the fourth positioning part can refer to the arrangement of the first positioning part and the second positioning part, and the specific structure is not limited.

[0405] Longitudinal positioning device 9

[0406] Please refer to Figures 94-100 , Fig.94 is a schematic structural diagram of a longitudinal positioning device provided by an embodiment of the present invention at the highest position; Fig.95 yes Fig.94 The main view; Fig.96 is a schematic diagram of the structure of the longitudinal positioning device in the lowest position; Fig.97 yes Fig.96 The main view; Fig.98 is a schematic diagram of the structure of the second base; Fig.99It is a structural schematic diagram of the sliding seat; Fig.100 It is a partial structural schematic diagram of the longitudinal positioning device.

[0407] The station equipment system further includes a longitudinal positioning device 9 disposed in the track 100, and a positioning structure is also disposed on the lower end surface of the support portion 4. Figures 94-97 As shown, the longitudinal positioning device 9 includes a second base 91, a sliding seat 92, a lifting part 94, a driving part and a positioning part 95, wherein the driving part can drive the sliding seat 92 to slide longitudinally relative to the second base 91, the lifting part 94 and the positioning part 95 are both arranged on the sliding seat 92, the lifting part 94 can lift and lower the positioning part 95, and the positioning part 95 is adapted to the positioning structure. When the positioning part 95 is in a raised state by the lifting part 94, the driving part can drive the sliding seat 92 to slide longitudinally relative to the second base 91, and drive the positioning part 95 arranged on the sliding seat 92 to slide longitudinally until it cooperates with the positioning structure arranged on the lower end surface of the supporting part 4, and then the driving part continues to drive, and can push the supporting part 4 through the coordinated action of the positioning part 95 and the positioning structure, so that it moves longitudinally to a preset position.

[0408] The longitudinal positioning device 9 can drive the vehicle to move to a preset position, so that each main body and supporting part 4 respectively corresponds to the setting position of other loading and unloading station equipment (including the chassis lifting device 7, the supporting part lifting device 8 and the translation device, etc.) arranged on the platform, thereby ensuring smooth loading and unloading.

[0409] Specifically, the longitudinal positioning device 9 is arranged in the track 100 of the loading and unloading station yard, and the lower end surface of the supporting portion 4 is provided with a positioning structure, and the positioning structure is adapted to the limiting mechanism of the longitudinal positioning device 9 provided in this embodiment. When the supporting portion 4 is located within the preset range after the back vehicle stops, the lifting portion 94 of the longitudinal positioning device 9 is started to make the positioning portion 95 in a raised state. At this time, the positioning portion 95 and the positioning structure are at the same height, and then the driving portion is started, so that the sliding seat 92 drives the positioning portion 95 to move longitudinally until the positioning portion 95 is 5 cooperates with the positioning structure of the lower end surface of the supporting part 4, and then the driving part continues to drive and pushes the supporting part 4 to move longitudinally to the preset position through the action of the positioning part 95 and the limiting structure. At this time, the chassis and the supporting part 4 of the piggyback vehicle correspond to the setting positions of other loading and unloading station equipment respectively, and then the chassis and the supporting part 4 can be lifted by the chassis lifting device 7, and then the supporting part 4 can be lifted by the supporting part lifting device 8 to separate it from the chassis, and then the supporting part 4 can be driven by the translation device to translate to the assembly station outside the track 100, and then the loading and unloading operation can be carried out.

[0410] That is to say, when the saddlebag arrives at the loading and unloading station and stops, the position of the chassis and the support part 4 is not necessarily the above-mentioned preset position, but is located within the preset distance range of the preset position. At this time, the longitudinal positioning device 9 provided in this embodiment can push the support part 4 to move it longitudinally to the preset position to achieve accurate positioning of the longitudinal position of the chassis and the support part 4, which is convenient for the later movement of the chassis lifting device 7, the support part lifting device 8 and the translation device. The longitudinal positioning device 9 has a simple structure, and only needs to be acted on by the lifting part 94 and the driving part so that the positioning part 95 cooperates with the positioning structure of the lower end surface of the support part 4 and pushes the support part 4. It has a simple structure and good stability.

[0411] The preset range refers to a range within a certain distance from the preset position. The longitudinal positioning device 9 is fixed on the rail surface. When the position where the support part 4 stops is within the preset range, it can be longitudinally positioned by the longitudinal positioning device 9. If it exceeds the preset range, it exceeds the action stroke of the longitudinal positioning device 9 and the piggyback vehicle cannot reach the preset position. Specifically, when the stop position of the support part 4 is within the preset range, it may be in front of the preset position or in the rear of the preset position. Therefore, for the same loading and unloading station, the longitudinal position of each support part 44 of the piggyback vehicle can be adjusted to reach the preset position by setting one or more groups of two longitudinal positioning devices 9 arranged opposite to each other in the longitudinal direction, which has better flexibility.

[0412] In the above embodiment, the positioning portion 95 includes a crossbeam 951 and a positioning block 952 fixed to the crossbeam 951. The two ends of the crossbeam 951 are respectively provided with second rollers 953 that can roll along the lower end surface of the support portion 4. When the vehicle stops within a preset range, the positioning portion 95 is in a disengaged state from the positioning structure. Then, the lifting portion 94 acts on the positioning portion 95 to make its height consistent with the height of the positioning structure. Then, the driving portion drives the sliding seat 92 to drive the positioning portion 95 to slide to cooperate with the positioning structure. During the process, the positioning portion 95 is in a sliding state relative to the support portion 4. The provision of the second roller 953 can reduce the sliding friction between the positioning portion 95 and the lower end surface of the support portion 4 during this process, thereby reducing friction and wear and extending the service life.

[0413] There is no specific limitation on the arrangement of the positioning block 952 and the positioning structure. Fig.100 As shown, in this embodiment, the positioning portion 95 is a triangular positioning block 952, and accordingly, the positioning structure can be set as a V-shaped notch or pit located on the transverse bracket of the support portion 4, or the positioning block 952 can be set as a square block or a circular block.

[0414] In the above embodiment, the lifting part 94 is an air spring arranged on the sliding seat 92. Due to the effect of the bogie spring, when the support part 4 is in an unloaded state, its height is the highest, and when the support part 4 is loaded with a road vehicle, its height is lower than the height when it is unloaded. Therefore, when the lifting part 94 is set as an air spring, its height after inflation has elastic adjustment. Compared with the rigid height-raising device, it can adapt to different height requirements of the support part 4 in different states and has better applicability. Specifically, the lower end of the positioning part 95 (crossbeam 951) can also be provided with an abutment plate 954 for abutting against the air spring to increase the action area between the two and improve stability.

[0415] Furthermore, the sliding seat 92 is also provided with a swinging member, which includes a hinged end and an action end, wherein the hinged end is hinged to the sliding seat 92, and the top end of the air spring can push the action end to swing around the hinged end, and the above-mentioned crossbeam 951 is fixed to the action end. In other words, after the air spring is inflated, it can push the action end upward to rotate around the hinged end, and when the air spring is exhausted, the action end will rotate around the hinged end and drop to the lowest position (such as Fig.96 and Fig.97 As shown), the setting of the swing member can ensure the stability of the positioning portion 95 while simplifying the overall structure.

[0416] Furthermore, the swing member includes two parallel and spaced apart swing rods 96, or, in this embodiment, the swing member can also be configured as a whole plate-like structure, one side of the plate-like structure is hinged to the sliding seat 92, and the other side is fixed to the crossbeam 951. The solution of two swing rods 96 can simplify the overall structure and reduce the weight.

[0417] In the above embodiment, the driving part includes a second hydraulic cylinder 93 hinged to the second base 91, and the end of the second piston rod 931 of the second hydraulic cylinder 93 is hinged to the positioning part 95. The second piston rod 931 of the second hydraulic cylinder 93 pushes and pulls the positioning part 95 so that the sliding seat 92 and the positioning part 95 slide longitudinally as a whole. Alternatively, in this embodiment, the second piston rod 931 of the hydraulic rod can also act on the sliding seat 92, that is, directly push and pull the sliding seat 92 to drive the positioning part 95 to slide longitudinally. When the second piston rod 931 of the second hydraulic cylinder 93 is hinged to the positioning part 95, when the second piston rod 931 is in a retracted state, part of the second hydraulic cylinder 93 is located above the sliding part (between the two rocker arms 96), which can reduce the distance between the end of the sliding seat 92 and the end of the second base 91, thereby reducing the overall volume of the longitudinal positioning device 9.

[0418] Alternatively, in this embodiment, the driving part can also be set to a structure including a motor, a gear and a rack, or it can be set to a structure including a motor, a screw and a nut. In this case, the driving part can be fixed to the second base 91 and directly act on the sliding seat 92 to make it slide longitudinally relative to the second base 91. When the driving part is set to the second hydraulic cylinder 93, the overall structure can be simplified and the stability can be better.

[0419] In the above embodiment, the longitudinal positioning device 9 further includes a limiter 97, which is used to limit the lifting height of the action end so that when the action end is raised to the highest position (such as Fig.94 and Fig.95 As shown), the positioning portion 95 can cooperate with the positioning structure of the support portion 4 in a no-load state. With this arrangement, when the air spring is inflated to push the positioning portion 95 upward, damage to the inflated spring due to excessive inflation pressure can be avoided, thereby providing inflation protection for the air spring.

[0420] Specifically, the limiting portion 97 includes a first connecting rod 971 and a second connecting rod 972 which are hinged to each other. Fig.99 and Fig.100 As shown, the sliding seat 92 is provided with a first hinge seat 921, the positioning portion 95 (crossbeam 951) is provided with a second hinge seat 9511, the end of the first connecting rod 971 is hinged to the first hinge seat 921, and the end of the second connecting rod 972 is hinged to the second hinge seat 9511. When the lifting portion 94 lifts and lowers the positioning portion 95, it can drive the second connecting rod 972 to expand or fold relative to the first connecting rod 971 through the action end. In other words, when the lifting portion 94 lifts and lowers the positioning portion 95, the angle between the two connecting rods (the first connecting rod 971 and the second connecting rod 972) changes, and when the angle between the two is expanded to the maximum, the air spring can be limited. Alternatively, in this embodiment, the limiting portion 97 can also be set as a chain or a pull rope, and the air spring can be limited when the chain or the pull rope is in a straightened state. When the limiting portion 97 is configured as two connecting rods that are hinged to each other and foldable, after the air spring is exhausted, the two connecting rods are in a folded state, at which time the heights of the two connecting rods are relatively low and will not hinder the descent of the positioning portion 95.

[0421] Furthermore, the limiting portion 97 further includes a limiting structure provided on the first connecting rod 971 and / or the second connecting rod 972, and the limiting structure can limit the maximum angle of rotation between the first connecting rod 971 and the second connecting rod 972 to be less than 180°. Such a setting can avoid the formation of a dead point after the angle between the two connecting rods reaches 180°, which affects the descent of the positioning portion 95. Specifically, one of the first connecting rod 971 and the second connecting rod 972 may be provided with a limiting structure, and when the two are rotated to the maximum angle, the limiting structure can abut against the other connecting rod to limit its continued rotation, or it may also include limiting structures respectively provided on the two connecting rods and adapted to each other, and when the angle between the two reaches the maximum, it can limit the continued rotation.

[0422] In the above embodiment, if Fig.98 As shown, the second base 91 is provided with a third slideway 911 in the longitudinal direction, and the sliding seat 92 is provided with a slider 922 capable of sliding along the third slideway 911. Specifically, as shown in FIG. Fig.99 and Fig.100 As shown, in this embodiment, the third slide 911 is a slide groove provided on the second base 91, and a slider 922 located in the slide groove and capable of sliding along the slide groove is provided on the edge of the slide seat 92. Alternatively, the slide groove can be provided on the upper end surface of the second base 91, and a slider 922 capable of sliding along the slide groove is provided on the lower end surface of the slide seat 92. Of course, in this embodiment, the third slide 911 can also be provided as a strip hole or a slide rail provided in the longitudinal direction, and no specific limitation is made here.

[0423] Of course, in this embodiment, the third slideway 911 can also be provided on the sliding seat 92, and the second base 91 can slide along the third slideway 911. Since the second base 91 is fixed on the rail surface, the sliding seat 92 can slide relative to the second base 91. When the third slideway 911 is provided on the second base 91, the sliding continuity of the sliding seat 92 can be ensured to be good.

[0424] In addition, in this embodiment, the hinged connection between the above-mentioned components can be connected by a pin or a round pin, and the pin or the round pin can be limited by a washer and a split pin. The two support rods are cross-arranged and can rotate around the intersection respectively, and the two can also be connected by the above-mentioned pin or round pin, or the pin can be fixed to one of the support rods, and the other support rod is provided with a pin hole, and the pin passes through the pin hole and is limited by a washer and a split pin.

[0425] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
