Description

Technical Field

[0001] The invention relates to the technical field of piggyback vehicles, and in particular to a station equipment system for loading and unloading a translational piggyback vehicle. Background Art

[0002] Piggyback transport refers to a convenient mode of transport in which a road vehicle such as a road truck or semi-trailer is loaded with goods and driven onto the piggyback vehicle at the departure railway station, and the goods are transported over long distances by rail. After arriving at the destination railway station, the road vehicle can drive off the piggyback vehicle and drive to the final destination.

[0003] The body of a saddlebag generally includes a main body and a detachable support. When loading and unloading, the support can be firstly moved horizontally from the main body and separated to facilitate the loading and unloading of road vehicles. After loading and unloading, the support can be installed on the main body. If the driving mechanism for driving the support to move horizontally and separate from the main body is set in the body, the overall structure of the body will be more complicated, and the weight and cost of the body will also increase.

[0004] Therefore, how to set up a station equipment system suitable for loading and unloading translatory piggyback vehicles at a loading and unloading station, so as to realize the translational separation and installation of the supporting part of the translatory piggyback vehicle docked at the loading and unloading station, simplify the overall structure of the translatory piggyback vehicle, achieve lightweight and reduce costs, is a technical problem that needs to be solved by technical personnel in this field. Summary of the invention

[0005] The object of the present invention is to provide a station equipment system for a translatory piggyback loading and unloading vehicle, which can realize the translational separation and installation of the supporting part of the translatory piggyback parked at the loading and unloading station, thereby simplifying the overall structure of the translatory piggyback, achieving lightweight and reducing costs.

[0006] In order to solve the above technical problems, the present invention provides a station equipment system for a translation-type piggyback loading and unloading vehicle, comprising a loading and unloading station, a translation device, two groups of end 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 end chassis lifting parts can respectively lift the end chassis at both ends of the supporting part; the two groups of supporting part lifting parts can respectively lift the two ends of the supporting part to separate the supporting part from the end chassis; when the supporting part is in a detached state from the end chassis, the translation device can move the supporting part between the track and the loading and unloading station.

[0007] When the piggyback vehicle reaches the preset position of the loading and unloading station yard, a group of end frame lifting parts are respectively provided under the front and rear end frames 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 end frame lifting parts are first used to lift the end frames and the supporting part at the same time from both ends until the two groups of bogie center plates are no longer under force. The end frame 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 end frames. 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.

[0008] The end chassis 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 translational piggyback vehicle does not need to be provided with a corresponding lifting part and translation device. In this way, the translational piggyback vehicle can realize the lifting and translation operations at the loading and unloading station, simplify the overall structure of the translational piggyback vehicle, thereby reducing its own weight and improving economic efficiency. In addition, the station equipment system can cooperate with different translational piggyback vehicles passing through the track to load and unload goods, improve its applicability and further reduce costs.

[0051] 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.

[0052] Please refer to Figure 1-4 , Figure 1 It is a structural schematic diagram of a station equipment system for a translational piggyback loading and unloading vehicle provided by an embodiment of the present invention; Figure 2 yes Figure 1 Schematic diagram of the local structure; Figure 3 It is a top view of the packback vehicle in a preset position; Figure 4 It is a schematic diagram of the structure of the piggyback vehicle moving horizontally outside the track.

[0053] The embodiment of the present invention provides a station equipment system for loading and unloading a translational piggyback vehicle, such as Figure 1 and Figure 2As shown, the station equipment system includes a loading and unloading station, a translation device, two groups of end 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 end chassis lifting parts can respectively lift the end chassis 200 at both ends of the supporting part 400, so that the two groups of end chassis 200 drive the supporting part 400 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 400 to separate the supporting part 400 from the end chassis 200.

[0054] When the support 400 is in a disengaged state from the end base frame 200, the translation device can move the support 400 between the track 100 and the loading and unloading station, that is, the translation device can move the support 400 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 400 inward to the track 100 corresponding to the end base frame 200, and then the support 400 is lowered and cooperated with the end base frame 200 through the action of the support lifting part.

[0055] In detail, Figure 3 As shown, when the saddlebag truck reaches the preset position of the loading and unloading station, a group of end frame lifting parts are respectively provided under the two front and rear end frames 200 of the supporting part 400, and a group of supporting part lifting parts are respectively provided under the front and rear ends of the supporting part 400. The end frames 200 and the supporting part 400 are first lifted together from both ends by the two groups of end frame lifting parts until the two groups of bogie center plates are no longer under force. The end frame lifting parts keep their function unchanged, and then the supporting part 400 is continuously lifted upward from both ends by the two groups of supporting part lifting parts to separate it from the end frames 200. Then the supporting part lifting parts keep their function unchanged. Finally, the translation device acts on the supporting part 400 to translate it to the outside of the track 100 to the loading and unloading station, and then the loading and unloading operations can be carried out.

[0056] In this embodiment, the end chassis 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 translational piggyback vehicle does not need to be provided with a corresponding lifting part and translation device 600. In this way, the translational piggyback vehicle can simplify the overall structure of the translational piggyback 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 system can cooperate with different translational piggyback vehicles passing through the track 100 to load and unload goods, improve its applicability, and further reduce costs.

[0057] In the above embodiment, the station is provided with a translation path perpendicular to the track 100, and the support part 400 can move to the loading and unloading station along the translation path after being separated from the end chassis 200, and the translation device 600 includes a driving assembly and a translation part 640, and the driving assembly can drive the translation part 640 to drive the support part 400 to move along the translation path. In detail, after being lifted by the end chassis lifting part and the support part lifting part, the support part 400 is separated from the end chassis 200, and then the driving assembly drives the translation part 640 to move to the bottom of the support part 400 along the translation path, and the support part lifting part acts to make the support part 400 descend and fall on the translation part 640, and then the driving assembly acts on the translation part 640 to drive the support part 400 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 640 can drive the support part 400 to move in the opposite direction along the translation path to the track 100 and correspond to the end chassis 200.

[0058] Specifically, the translation path can be a slide rail or a slide groove, etc., to limit the movement of the translation part 640, to ensure that the translation part 640 can correspond to the end base frame 200 when driving the support part 400 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.

[0059] Alternatively, in this embodiment, the support part 400 can also be arranged to be moved to the side platform outside the track 100 by means of a mobile cart, and the overall structure can be simplified by setting the drive assembly, the translation part 640 and the translation path, and the stability of the translation can be ensured, thereby avoiding the deflection of the support part 400 during the translation process, and ensuring that it can move along the translation path.

[0060] Furthermore, the driving assembly includes an outer driving member 610 and an inner driving member 620, wherein the outer driving member 610 is arranged at the loading and unloading station of the side platform outside the track 100, and the inner driving member 620 is arranged inside the track 100. The top ends of the outer driving member 610 and the inner driving member 620 are respectively provided with driving wheels 630, and the axis of each driving wheel 630 is parallel to the track 100 (that is, perpendicular to the translation path), and the top end of each driving wheel 630 is abutted against the lower end surface of the translation part 640, and can drive the translation part 640 to move along the translation path. That is to say, driving wheels 630 are respectively provided outside the track 100 and inside the track 100, which are used to drive the translation part 640 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 400 to move along the translation path. The push-pull part is arranged on the side platform outside the track 100. Each driving wheel 630 is only an ordinary roller. The push-pull part can push and pull the supporting part 400 to make it roll along the roller. The solution of setting the external driving member 610 and the internal driving member 620 to have driving wheels 630 can simplify the overall structure.

[0061] In the above embodiment, the lower end surface of the translation part 640 is provided with a first limiter part, and the driving wheel 630 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 640 move along the translation path, thereby ensuring the stability and accuracy of the translation of the support part 400. 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.

[0062] In the above embodiment, the lower end surface of the support part 400 is provided with a first positioning part, and the upper end surface of the translation part 640 is provided with a second positioning part matched with the first positioning part. When the translation part 640 moves to the bottom of the support part 400, the first positioning part corresponds to the second positioning part, and then the support part 400 descends and is fixed to the translation part 640 through the cooperation of the first positioning part and the second positioning part, so that the support part 400 can be prevented from moving relative to the translation part 640 during the translation process, and it can also be ensured that when the translation part 640 moves into or out of the track 100, it can drive the support part 400 to correspond to the end chassis 200 and cooperate with the loading and unloading station, thereby ensuring stability and accuracy.

[0063] Specifically, there is no limitation on the structures of the first positioning part and the second positioning part. 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.

[0064] In the above embodiment, the loading and unloading station is further provided with a side platform lifting unit 500 for lifting the supporting unit 400. The side platform lifting unit 500 is used to lift and support the supporting unit 400 at the loading and unloading station, that is, after the supporting unit 400 is translated to the outside of the track 100 to the loading and unloading station by the translation device, the side platform lifting unit 500 will lift the supporting unit 400 upward, and then move the translation unit 640 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 400 is lowered by the side platform lifting unit 500 until the height difference between the two ends of the supporting unit 400 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.

[0065] Specifically, after the translation part 640 moves the support part 400 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 part 400. 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 part 400, or a groove can be provided in the loading and unloading station, and the side platform lifting part 500 can be arranged in the groove, so that the support part 400 can be descended to the height difference between its end and the side platform ground within a preset range, and it can be specifically set according to actual conditions to facilitate the smooth loading and unloading.

[0066] In the above embodiment, the platforms on both sides outside the track 100 are provided with external driving parts 610 and side platform lifting parts 500, 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 640 translates a supporting part 400 to the loading and unloading station of a side platform, the translation part 640 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 500, and the other supporting part 400 that has been loaded and unloaded is translated inward to correspond to the end frame 200. In this way, the loading and unloading efficiency of the camelback vehicle when passing through the loading and unloading station can be effectively improved.

[0067] 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 unit 640 can carry out the transport work of the support unit 400 between multiple loading and unloading stations and tracks 100, thereby simplifying the overall structure.

[0068] refer to Figure 5-12 , Figure 5 is a schematic structural diagram of the end chassis lifting device 700 in the highest position; Figure 6 yes Figure 5 perspective drawing; Figure 7 is a perspective view of the end chassis lifting device 700 in the lowest position; Figure 8 is a schematic diagram of the structure of the first base; Fig. 9 It is a structural schematic diagram of the support seat; Fig.10 It is a schematic diagram of the structure of the push rod; Fig.11 It is a structural diagram of the joystick; Fig.12 It is a schematic diagram of the structure of the first support rod.

[0069] Each group of the end frame lifting parts includes two end frame lifting devices 700 respectively located on both sides of the track 100, that is, there are four end frame lifting devices 700 in total, and end frame lifting devices 700 are respectively arranged on both sides of an end frame 200 to lift the end frame 200 from both sides. In this way, the lifting stability can be guaranteed and the strength requirement of a single end frame lifting device 700 can be reduced.

[0070] Specifically, in this embodiment, Figure 5-7 As shown, the end chassis lifting device 700 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 support 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 support assembly 74 includes a first support rod 741 and a second support rod 742 arranged crosswise, wherein the top end of the first support rod 741 is hinged to the first support base 72, the bottom end of the first support rod 741 can slide along the first slideway 711, the bottom end of the second support rod 742 is hinged to the first base 71, and the top end of the second support rod 742 can slide along the second slideway 721, and the driving mechanism can act on the first support assembly 74 to change the angle between the first support rod 741 and the second support rod 742, thereby changing the height of the first support base 72 from the first base 71.

[0071] Among them, the support seat 72 abuts against the lower end surface of one end of the end frame 200 toward the supporting part 400. 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 end frame 200 of the piggyback vehicle toward one end of the supporting part 400 until the center plate of the bogie is no longer under force, and the lifting operation of the supporting part 400 can be performed. At this time, since the end frame lifting device 700 can provide support for the end frame 200 so that it will not be deflected, and after the supporting part 400 is loaded and unloaded and cooperated with the end frame 200 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.

[0072] In detail, when the saddlebag vehicle arrives at the loading and unloading station, the parking position of the saddlebag vehicle is accurately located, and an end frame lifting device 700 (a total of four) is respectively provided on the left and right sides below the end frames 200 at the front and rear ends of the supporting part 400. Each end frame lifting device 700 acts to drive the front and rear end frames 200 toward one end of the supporting part 400 to drive the supporting part 400 to rise until the position where the bogie center plate is no longer under force. The end frame lifting device 700 keeps its position stable, and then acts on the supporting part 400 through the supporting part lifting part to make it rise, and through the action of the translation device, the supporting part 400 is translated to the outside of the track 100 to the loading and unloading station for easy loading and unloading.

[0073] In the above embodiment, 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 end frame lifting device 700 can provide stable support to the end frame 200 when in use.

[0074] 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.

[0075] 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.

[0076] like Figure 6 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, and the end chassis 200 continues to press down the support seat 72, and the angle between the two support rods tends to increase. Since the opening of the bend 7333 is downward and located just 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, so that the state of each support assembly 74 can be kept 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.

[0077] 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 automatic locking between the support assemblies 74 can be achieved. In this state, the vertical force cannot change the state of the support assemblies 74. Only when it is necessary to lower the end chassis 200, 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 drops to the lowest state (such as Figure 7 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.

[0078] Specifically, Figure 5-7As 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.

[0079] 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.10 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.

[0080] Further, such as Figure 8 As 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.

[0081] In the above embodiment, if Fig.11 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.

[0082] In the above embodiment, the end chassis lifting device 700 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 prevent the distance between the two from changing and affecting the lifting of the end chassis 200.

[0083] Furthermore, the end chassis lifting device 700 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 can realize that the bottom end of the first support rod 741 can 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.

[0084] 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.

[0085] 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.

[0086] In the above embodiment, if Fig. 9As shown, the end chassis lifting device 700 also includes an unlocking portion 77, which is arranged on the upper end surface of the support seat 72 and is used to unlock the lock between the end chassis 200 and the support portion 400. Specifically, the end chassis 200 and the support portion 400 are locked by a locking structure to avoid separation during driving. After the sled vehicle is accurately positioned at the loading and unloading station, the end chassis lifting device 700 is placed under the end chassis 200 so that the unlocking portion 77 on the upper end surface of the support seat 72 is aligned with the locking structure, and the support seat 72 is continuously raised so that the unlocking portion 77 cooperates with the locking structure and releases the locking effect of the locking structure during the process of lifting the end chassis 200 and the support portion 400, and then the support portion 400 is lifted by the lifting device. Alternatively, in this embodiment, the locking effect between the end chassis 200 and the support portion 400 can also be unlocked by an additionally arranged unlocking device, and when the unlocking portion 77 is arranged at the top of the support seat 72, the overall structure can be simplified while simplifying the operation.

[0087] In the above embodiment, if Figure 1 and Figure 2 As shown, the support lifting part includes two hydraulic lifting devices 800 respectively located on both sides of the track 100. That is to say, there are four hydraulic lifting devices 800 in total, and two hydraulic lifting devices arranged at intervals are arranged below one end of the support 400 to act on it and make it rise and fall. Such an arrangement can make the overall structure simple and stable.

[0088] 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 500, and the side platform lifting part 500 may also be configured as a hydraulic lifting device 800, or the supporting lifting part and the side platform lifting part 500 may also be configured as a structure that is the same as or similar to the structure of the end frame lifting device 700, such as a structure including a driving part, cross-arranged support rods, and a support seat.

[0089] Furthermore, the lower end surface of the supporting part 400 is provided with a third positioning part, and the top end of the hydraulic lifting device 800 is provided with a fourth positioning part adapted to the third positioning part, so as to ensure that the hydraulic lifting device 800 acts stably and can achieve accurate positioning during the process of lifting the supporting part 400. 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.

[0090] Please refer to Figure 13-19 , Fig.13 is a schematic structural diagram of the longitudinal positioning device 900 provided in an embodiment of the present invention at the highest position; Fig.14 yes Fig.13 The main view of Fig.15 is a schematic structural diagram of the longitudinal positioning device 900 in the lowest position; Fig.16yes Fig.15 The main view of Fig.17 is a schematic diagram of the structure of the second base; Fig.18 It is a structural schematic diagram of the sliding seat; Fig.19 It is a schematic diagram of the partial structure of the longitudinal positioning device 900.

[0091] The station equipment system also includes a longitudinal positioning device 900 disposed in the track 100. Figure 13-16 As shown, the longitudinal positioning device 900 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, the positioning part 95 is adapted to the positioning structure arranged on the lower end surface of the piggyback support part 400, when the lifting part 94 acts on the positioning part 95 to make it in a raised state, 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 support part 400, and then the driving part continues to drive, and can push the support part 400 through the coordinated action of the positioning part 95 and the positioning structure, so that it moves longitudinally to a preset position.

[0092] Among them, the longitudinal direction refers to the length direction of the saddlebag vehicle. The longitudinal positioning device 900 can drive the vehicle to a preset position, so that each main body part and the supporting part 400 respectively correspond to the setting positions of other loading and unloading station equipment (including the end frame lifting device 700, the supporting part lifting device 800 and the translation device, etc.) set on the platform, to ensure smooth loading and unloading.

[0093] Specifically, the longitudinal positioning device 900 is arranged in the track 100 of the loading and unloading station yard, and the lower end surface of the supporting part 400 is provided with a positioning structure, and the positioning structure is adapted to the limiting mechanism of the longitudinal positioning device 900 provided in this embodiment. When the piggyback vehicle stops and the supporting part 400 is located within the preset range, the lifting part 94 of the longitudinal positioning device 900 is started to make the positioning part 95 in a raised state. At this time, the positioning part 95 and the positioning structure are at the same height, and then the driving part is started so that the sliding seat 92 drives the positioning part 95 to move longitudinally until the positioning part 95 and the lower end surface of the supporting part 400 are aligned. The driving part continues to drive and pushes the supporting part 400 to move longitudinally to the preset position through the action of the positioning part 95 and the limiting structure. At this time, the end frames 200 and the supporting parts 400 of the saddlebag vehicle respectively correspond to the setting positions of other loading and unloading station equipment. Then, the end frame 200 and the supporting part 400 can be lifted by the end frame lifting device 700, and then the supporting part 400 can be lifted by the supporting part lifting device 800 to separate it from the end frame 200. Then, the supporting part 400 is driven by the translation device to translate to the assembly station outside the track 100, and then the loading and unloading operations can be carried out.

[0094] That is to say, when the saddlebag arrives at the loading and unloading station and stops, the position of the end chassis 200 and the support part 400 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 900 provided in this embodiment can push the support part 400 to move it longitudinally to the preset position to achieve accurate positioning of the longitudinal position of the end chassis 200 and the support part 400, which is convenient for the later movement of the end chassis lifting device 700, the support part lifting device 800 and the translation device. The longitudinal positioning device 900 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 400 and pushes the support part 400. It has a simple structure and good stability.

[0095] The preset range refers to a range within a certain distance from the preset position. The longitudinal positioning device 900 is fixed on the rail surface. When the position where the support part 400 stops is within the preset range, it can be longitudinally positioned by the longitudinal positioning device 900. If it exceeds the preset range, it exceeds the action stroke of the longitudinal positioning device 900, and the piggyback vehicle cannot reach the preset position. Specifically, when the stop position of the support part 400 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 400400 of the piggyback vehicle can be adjusted to reach the preset position by setting one or more groups including two longitudinal positioning devices 900 arranged opposite to each other in the longitudinal direction, which has better flexibility.

[0096] 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 400. When the vehicle stops within a preset range, the positioning portion 95 is disengaged 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 until it cooperates with the positioning structure. During this process, the positioning portion 95 is in a sliding state relative to the support portion 400. 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 400 during this process, thereby reducing friction and wear and extending the service life.

[0097] There is no specific limitation on the arrangement of the positioning block 952 and the positioning structure. Fig.19 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 of the transverse bracket located on the support portion 400, or the positioning block 952 can be set as a square block or a circular block.

[0098] 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 400 is in an unloaded state, its height is the highest, and when the support part 400 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 400 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.

[0099] 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.15 and Fig.16 As shown), the setting of the swing member can ensure the stability of the positioning portion 95 while simplifying the overall structure.

[0100] 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.

[0101] 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 900.

[0102] 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.

[0103] In the above embodiment, the longitudinal positioning device 900 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.13 and Fig.14 As shown), the positioning portion 95 can cooperate with the positioning structure of the support portion 400 in a no-load state. Such a configuration can avoid the situation where the air spring is damaged due to excessive inflation pressure when the air spring is inflated to push the positioning portion 95 upward, thereby providing inflation protection for the air spring.

[0104] Specifically, the limiting portion 97 includes a first connecting rod 971 and a second connecting rod 972 which are hinged to each other. Fig.18 and Fig.19As 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.

[0105] 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.

[0106] In the above embodiment, if Fig.17 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.18 and Fig.19 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.

[0107] 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.

[0108] 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.

[0109] 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.
