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 rotary piggyback vehicles. 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 vehicle generally includes a main body and a detachable support. When loading and unloading the vehicle, the support can be rotated and separated from the main body to facilitate the loading and unloading of road vehicles. After loading and unloading the vehicle, the support can be installed on the main body. If the driving mechanism for driving the support to rotate and separate from the main body is set on the vehicle body, the overall structure of the vehicle body will be more complicated, and the weight and cost of the vehicle body will also increase.

[0004] Therefore, how to set up a station equipment system suitable for rotating piggyback vehicles at a loading and unloading station yard, so as to realize the rotation, separation and installation of the support part of the rotating piggyback vehicle parked at the loading and unloading station yard, simplify the overall structure of the rotating 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 rotary piggyback loading and unloading vehicle, which can realize the rotation, separation and installation of the support part of the rotary piggyback parked at the loading and unloading station from the main body, simplify the overall structure of the rotary piggyback, achieve lightweight and reduce costs.

[0006] In order to solve the above technical problems, the present invention provides a station equipment system for a rotary piggyback loading and unloading vehicle, which includes a rotating device, two groups of end frame lifting parts, two groups of supporting part lifting parts and two groups of slope transition devices arranged outside the track; the two groups of end frame lifting parts can respectively lift the end frames 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 frame; when the supporting part is in a disengaged state from the end frame, the rotating device can drive the supporting part to rotate around its rotation axis, and when the supporting part rotates to a preset angle, the two ends of the supporting part can respectively connect with the two groups of slope transition devices.

[0007] When the saddlebag 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 of the supporting part until the bogie center plate is 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 rotating device acts on the supporting part to rotate it around its rotation axis to a preset angle. After the two ends are respectively connected with the slope transition device, the slope transition device can form a transition connection between the ground and the supporting part, which is convenient for loading and unloading the vehicle.

[0008] The end chassis lifting part, the supporting part lifting part and the rotating device are all arranged at the loading and unloading station yard, so that the main body of the rotary piggyback vehicle does not need to be provided with corresponding lifting parts and rotating devices. In this way, the overall structure of the rotary piggyback vehicle can be simplified while realizing the lifting and rotating operations of the rotary piggyback vehicle at the loading and unloading station yard, thereby reducing its own weight and improving economic efficiency. In addition, a set of various equipment arranged at the loading and unloading station yard can cooperate with different rotary piggyback vehicle loading and unloading vehicles passing through the track, thereby improving its applicability and further reducing costs.

[0070] 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.

[0071] Please refer to Figure 1-6 , Figure 1 It is a structural schematic diagram of a station equipment system for a rotary piggyback loading and unloading vehicle provided by an embodiment of the present invention; Figure 2 yes Figure 1A top view of Figure 3 It is a top view of the packback vehicle after it has traveled to a preset position; Figure 4 yes Figure 3 Front view of Figure 5 It is a schematic diagram of the structure after the support part is rotated by a certain angle; Figure 6 is a schematic diagram of the structure after the support part is rotated to a preset angle;

[0072] The embodiment of the present invention provides a station equipment system for loading and unloading a rotating piggyback vehicle, such as Figure 1 and Figure 2 As shown, the station equipment system includes a rotating device 600, two sets of end frame lifting parts, two sets of support lifting parts and two sets of slope transition devices 300, wherein the two sets of slope transition devices 300 are arranged on the side platform outside the track 100. The two sets of end frame lifting parts are respectively arranged below the end frames 200 at both ends of the support 400, and are used to simultaneously lift the end frames 200 at both ends of the support 400, so that the end frames 200 drive the support 400 to move upward until the center plate of the bogie is no longer stressed; the two sets of support lifting parts are respectively arranged below the two ends of the support 400, and are used to simultaneously lift the support 400 from both ends so that the support 400 is separated from the end frame 200; the rotating device 600 is used to drive the support 400 to rotate around its rotation center to a preset angle after the support 400 is separated from the end frame 200 so that the two ends of the support 400 can be connected with the two sets of slope transition devices 300 respectively.

[0073] In detail, Figure 3-6 As shown, when the saddlebag vehicle reaches the preset position of the loading and unloading station, a group of end frame lifting parts are respectively provided under the 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. First, the end frames 200 and the supporting part 400 are lifted together from both ends of the supporting part 400 by the two groups of end frame lifting parts until the position where the bogie center plate is no longer subjected to force, and 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, and then the supporting part lifting parts keep their function unchanged, and finally the rotating device 600 acts on the supporting part 400 to rotate it around its rotation axis to a preset angle, and after the two ends are respectively connected with the slope transition device 300, the slope transition device 300 can form a transition connection between the ground and the supporting part 400, so as to facilitate the loading and unloading of the vehicle.

[0074] In this embodiment, the end chassis lifting part, the supporting part lifting part and the rotating device 600 are all arranged at the loading and unloading station yard, so that the main body of the rotary piggyback vehicle does not need to be provided with the corresponding lifting part and the rotating device 600. In this way, the overall structure of the rotary piggyback vehicle can be simplified while realizing the lifting and rotating operations of the rotary piggyback vehicle at the loading and unloading station yard, thereby reducing its own weight and improving economic efficiency. In addition, a set of various equipments arranged at the loading and unloading station yard can cooperate with different rotary piggyback vehicle loading and unloading vehicles passing through the track 100, thereby improving its applicability and further reducing costs.

[0075] In the above embodiment, the station equipment system also includes a center positioning device 500, which is arranged in the track 100, and includes a lifting mechanism and a positioning shaft arranged at the top of the lifting mechanism. The lower end surface of the support part 400 is provided with a positioning shaft hole or pit matched with the positioning shaft along its rotation axis.

[0076] When the piggyback vehicle travels to the preset position, the positioning shaft hole or pit on the lower end face of the support part 400 just corresponds to the positioning shaft of the center positioning device 500 arranged in the track 100. The positioning shaft is located directly below the positioning shaft hole or pit. It is lifted by the end frame lifting part, and then the support part 400 is lifted by the support part lifting part to separate it from the end frame 200. Then, the lifting mechanism of the center positioning device 500 is started to lift the positioning shaft, so that the positioning shaft rises to cooperate with the positioning shaft hole or pit. The positioning shaft is the rotating shaft of the support part 400. Then, the rotating device 600 acts on the support part 400 to rotate it around the positioning shaft to a preset angle and connect with the slope transition device 300.

[0077] After the loading and unloading of the vehicle is completed, the rotating device 600 acts on the supporting part 400 to make it rotate in the opposite direction around the positioning axis until the supporting part 400 rotates to a preset angle to the top of the end frame 200, and then drives the lifting mechanism to make the positioning axis drop to its original position so that it no longer acts on the supporting part 400, and then the supporting part lifting part acts to make the supporting part 400 drop and cooperate with the end frame 200, and finally, the end frame lifting part acts to make the end frame 200 drive the supporting part 400 to drop until it cooperates with the bogie.

[0078] Alternatively, in the present embodiment, a rotation axis can also be provided on the main body of the saddlebag vehicle, such as by providing a bracket below the supporting portion 400 whose two ends are respectively fixed to the two end frames 200, and the rotation axis is provided on the bracket. When a center positioning device 500 is provided at the loading and unloading station yard, the supporting portion 400 only needs to be provided with a corresponding positioning axis hole or a recess, and the main body does not need to be provided with a rotation axis. Under this setting, no other structure is required to be provided below the supporting portion 400 of the saddlebag vehicle, but when the two ends of the supporting portion 400 cooperate with the end frames 200, the bottom of the supporting portion 400 is in a suspended state, thereby further simplifying the structure of the body of the saddlebag vehicle and making it lighter.

[0079] The above-mentioned center positioning device 500 can be arranged in an area close to the longitudinal center of the support part 4, so that the two sets of end chassis lifting parts are symmetrically arranged about the positioning axis, the two sets of support lifting parts are symmetrically arranged about the positioning axis, and the two sets of ramp transition devices 300 are symmetrically arranged about the positioning axis. The center positioning device 500 can also be arranged in an area close to the two longitudinal ends of the support part 4, or can also be arranged in other positions, as long as the rotation of the support part 4 around the positioning axis can be realized.

[0080] In the above embodiment, the station equipment system also includes a limit stopper 310 disposed on the ground. When the support part 400 rotates to abut against the limit stopper 310, it indicates that the support part 400 has rotated to the above preset angle. At this time, the two ends of the support part 400 can be respectively connected with the slope transition device 300 disposed on the ground, and the loading and unloading operation can be performed. Alternatively, in this embodiment, the support part 400 can stop after rotating to a preset angle by controlling the driving action of the rotating device 600, and the solution of limiting its rotation angle by the limit stopper 310 can simplify the overall structure while ensuring good stability.

[0081] Please refer to Figure 7-14 , Figure 7 It is a schematic diagram of the structure of the end chassis lifting device in the highest position; Figure 8 yes Figure 7 perspective drawing; Fig. 9 is a perspective view of the end chassis lifting device in the lowest position; Fig.10 is a schematic diagram of the structure of the first base; Fig.11 is a structural schematic diagram of a first support seat; Fig.12 is a schematic diagram of the structure of the first push rod; Fig.13 is a schematic diagram of the structure of the first rocker; Fig.14 It is a schematic diagram of the structure of the first support rod.

[0082] 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.

[0083] Specifically, in this embodiment, Figure 7-9As 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.

[0084] Among them, the first support seat 72 abuts against the lower end surface of one end of the end chassis 200 toward the supporting part 400. When the driving mechanism acts on the first support assembly 74 to reduce the angle between the first support rod 741 and the second support rod 742, the height of the first support assembly 74 increases, thereby driving the first support seat 72 to rise relative to the first base 71, and then lifting the end chassis 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 supporting part 400 can be lifted by the supporting part lifting device 800. At this time, the end chassis 200 will not be deflected due to the support of the end chassis lifting device 700. After the supporting part 400 is loaded and unloaded and cooperated with the end chassis 200 again, the driving mechanism acts on the first support assembly 74 to increase the angle between the first support rod 741 and the second support rod 742, so that the height of the first support assembly 74 decreases, thereby driving the first support seat 72 to descend to its original position relative to the first base 71.

[0085] In the above embodiment, the driving mechanism includes a first driving member 731 and a first locking assembly 732. The first driving member 731 is arranged on the first base 71 and provides a power source, which acts on the first 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 first support seat 72 rises to the highest position, the first locking assembly 732 can lock the relative positions of the two support rods, that is, keep the state of the first support assembly 74 unchanged, so that the height position of the first support seat 72 is stable, and the first support seat 72 is prevented from falling due to sudden failure of the first driving member 731, thereby ensuring that the end frame lifting device 700 can provide stable support to the end frame 200 when in use.

[0086] The first locking member 732 is preferably a first locking member 732 that is movable along the length of the first support rod 741 and that is movable along the length of the first support rod 741. The first locking member 732 is preferably a first locking member 732 that is movable along the length of the first support rod 741 and that is movable along the length of the first support rod 741.

[0087] In detail, the opening of the first bend 7333 is downward, the first rocker arm 734 is hinged between the second section 7332 and the first pin seat 712, and the first driving member 731 can act on the first bend 7333 and drive the first rocker arm 734 to rotate around the hinge point between it and the first pin seat 712, thereby driving the first push rod 733 to rotate around the hinge point between the first bend 7333 and the first 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.

[0088] like Figure 8 When the first support rod 741 is in the state of being lifted up, the first support seat 72 is lifted up and the first support rod 74 is in the state of being lifted up, so that the first support rod 741 and the first support rod 74 are in the state of being lifted up, and the first support rod 74 is in the state of being lifted up.

[0089] By setting the above-mentioned locking device, when the first driving member 731 raises the first support seat 72 to the highest position through the first support assembly 74, the first support assemblies 74 can be automatically locked. In this state, the vertical force cannot change the state of each first support assembly 74. Only when it is necessary to lower the end base frame 200, the first driving member 731 provides a reverse force to make the first push rod 733 move horizontally until the first bend 7333 is disengaged from the first pin seat 712, which can 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 first support seat 72 drops to the lowest state (such as Fig. 9 The first locking assembly 732 can achieve locking and unlocking while achieving the lifting and lowering of the first 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.

[0090] Specifically, Figure 7-9 As shown, in this embodiment, the first driving member 731 is a hydraulic cylinder, the piston rod of the hydraulic cylinder is hinged with the first bend 7333 of the first push rod 733, the two sides of the first support seat 72 are respectively connected through the first support assembly 74 and the first base 71, and the hydraulic cylinder and the bottom end of the first support rod 741 of one of the first support assemblies 74 can realize the overall lifting of all the first 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.

[0091] In the above embodiment, a connecting shaft is further provided at the end of the first section 7331 of the first push rod 733, and the connecting shaft sleeve is provided with a first roller 7335. When the first driving member 731 acts on the first bend 7333 to rotate the first push rod 733 around the hinge point between the first bend 7333 and the first 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 first 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 first push rod 733 can be as follows: Fig.12 As shown, it includes two first V-shaped connecting members 7334 arranged in parallel, and a connecting shaft is also provided between the ends of the two first 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.

[0092] Further, such as Fig.10 As shown, the first base 71 is also provided with a first rolling plate 713, and the first roller 7335 can roll along the first 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 first rolling plate 713 can be replaced after it is worn, thereby ensuring the service life of the first base 71.

[0093] In the above embodiment, if Fig.13 As shown, the first rocker 734 is provided with a first concave notch 7341 at one end facing the first pin seat 712, and the two side walls of the first concave notch 7341 and the first pin seat 712 are respectively provided with first shaft holes 7342, and the first pin seat 712 is provided in the first concave notch 7341 and is rotatably connected via a pin shaft passing through the first shaft hole 7342. Alternatively, in this embodiment, one end of the first rocker 734 can also be provided at one side of the first pin seat 712 and connected via a pin shaft, and the first rocker 734 is provided with the first concave notch 7341 and the first pin seat 712 is located in the first concave notch 7341, so that the connection between the two can be more stable and avoid the occurrence of deflection and jamming.

[0094] In the above embodiment, the end chassis lifting device 700 further includes a first upper sliding shaft 75 and a first roller sleeve 751 sleeved outside the first upper sliding shaft 75. The two sides of the first support seat 72 are connected to the first base 71 through the symmetrically arranged first support assembly 74. The first upper sliding shaft 75 passes through the top of the second support rod 742 of the symmetrically arranged first support assembly 74 and can slide along the second slideway 721. The first roller sleeve 751 is located between the two second support rods 742 and rolls against the first support seat 72. In other words, the first support assembly 74 and the first support seat 72 are acted on by the first roller sleeve 751 to ensure the supporting force between the first support assembly 74 and the first support seat 72, and the stability is good. At the same time, the first 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 and lowering of the end chassis 200.

[0095] Furthermore, the end chassis lifting device 700 further includes a first lower sliding shaft 76, which passes through the bottom end of the first support rod 741 of the symmetrically arranged first support assembly 74 and the first section 7331 of the first push rod 733, and can slide along the first slideway 711. The arrangement of the first 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 first push rod 733, which can simplify the overall structure.

[0096] Furthermore, Fig.14As shown, first reinforcing sleeves 7411 are respectively provided on both sides of the bottom end of the first support rod 741 and sleeved outside the first lower sliding shaft 76. The provision of the first reinforcing 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 first push rod 733, avoid deflection, and have good stability.

[0097] In the above embodiment, the first base 71 and the first support seat 72 are respectively provided with side plates, and the first slideway 711 and the second slideway 721 are both long holes provided on the side plates. 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.

[0098] In the above embodiment, if Fig.11 As shown, the end chassis lifting device 700 also includes an unlocking portion 77, which is arranged on the upper end surface of the first 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 support portion 400 is accurately positioned at the loading and unloading station, the end chassis lifting device 700 is placed below the end chassis 200 so that the unlocking portion 77 on the upper end surface of the first support seat 72 is aligned with the locking structure, and the first 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 first support seat 72, the overall structure can be simplified while simplifying the operation.

[0099] In addition, in this embodiment, there is no limitation on the specific structure of the above-mentioned center positioning device 500. For example, the end frame lifting device 700 can also be used as a lifting mechanism in the center positioning device 500, and the positioning axis can be set on the upper end surface of the first support seat 72.

[0100] Please refer to Figure 15-23 , Fig.16 yes Fig.15 perspective drawing; Fig.17 is a perspective view of the support lifting device in the lowest position; Fig.18 is a schematic diagram of the structure of the second base; Fig.19 is a structural schematic diagram of the second support seat; Fig. 20 It is a schematic diagram of the structure of the pusher; Fig.21 is a schematic diagram of the structure of the second push rod; Fig. 22 is a schematic diagram of the structure of the second rocker; Fig.23 It is a schematic diagram of the structure of the third support rod.

[0101] In the above embodiment, each set of supporting and lifting parts includes a supporting and lifting device 800 disposed in the track 100. Figure 15-17 As shown, the supporting lifting device 800 includes a second base 81, a second supporting seat 82, a supporting mechanism and a driving mechanism, wherein the supporting mechanism is connected between the second base 81 and the second supporting seat 82, and the driving mechanism can act on the supporting mechanism to lift the second supporting seat 82. In this embodiment, the upper end surface of the second supporting seat 82 is also provided with a rotating driving part, and the rotating driving part includes at least two driving wheels 87 arranged at intervals, and the upper end surface of the driving wheel 87 abuts against the lower end surface of the supporting part 400 and can push the supporting part 400 to rotate around its rotation axis. Each lifting device includes at least two driving wheels 87, and the extended lines of the axes of the driving wheels 87 pass through the rotation center of the support part 400 and are evenly arranged along the lower end surface of the support part 400. The upper end surface of the second support seat 82 is provided with a mounting frame 822 for mounting the driving wheels 87. The driving wheels 87 of the same lifting device are used to rotationally drive the support part 400 from one end, and the upper end surface of each driving wheel 87 abuts against the lower end surface of the support part 400. When the driving wheel 87 rotates, it can drive one end of the support part 400 to deflect. When the driving wheels 87 of the two lifting devices rotate in different directions (one end to the left and the other end to the right) at both ends at the same time, they can act on the support part 400 from both ends to make it rotate around its rotation axis. Specifically, the rotation axis can be formed by a rotation axis arranged on the ground, and the rotation axis is matched with the lower end surface of the support part 400. The two are not subjected to force in the vertical direction, and the support part 400 can rotate around the rotation axis.

[0102] Among them, the driving mechanism is used to drive the second support seat 82 to rise and fall through the supporting mechanism, thereby driving the rotary drive unit to rise and fall and act on or disengage from the lower end surface of the support part 400. In detail, after the end chassis 200 and the support part 400 are lifted as a whole to the center plate of the bogie by the lifting device of the end chassis 200 and are no longer subjected to force, the support part 400 is lifted by the support part lifting device 800 provided in this embodiment. Specifically, the two lifting devices are placed on the track 100, and act on the support part 400 from the front and rear ends respectively. The second support seat 82 drives the rotary drive unit to rise to the point where it can cooperate with the support part 400 through the action of the driving mechanism, and then starts the rotary drive unit to drive the support part 400 to rotate around its rotation axis to an appropriate angle so that it can cooperate with the inclined surface transition device on the ground, and then performs loading and unloading operations.

[0103] That is to say, the support lifting device 800 provided in this embodiment can drive the support 400 to rotate around its rotation axis after smoothly lifting the support 400 to a preset height, so that the support 400 can be easily rotated relative to the second support seat 82 after being lifted, thereby reducing the requirements for the rotating device 600 used to rotate the support 400 later. When the support 400 rotates around its rotation axis, rolling friction is formed between the support 400 and the second support seat 82 through the driving wheel 87, thereby reducing the wear between the two.

[0104] Specifically, Figure 1 As shown, the number of the driving wheels 87 in this embodiment is two, and may also be three or more equally spaced to ensure that the two lifting devices can stably support and rotationally drive the supporting portion 400 from both ends.

[0105] In the above embodiment, the support mechanism includes support parts provided below the second support seat 82 and corresponding to each driving wheel 87. That is to say, a support part is provided below each driving wheel 87, and the number of the support parts is not less than the number of the driving wheels 87. Since the lifting device lifts the supporting part 400 by abutting the end of the supporting part 400 with the driving wheel 87, the driving wheel 87 is subjected to a relatively large pressure. Each driving wheel 87 is provided with a support part to support it, which can reduce the strength requirement of the second support seat 82 while ensuring the stability of the overall structure of the lifting device.

[0106] In the above embodiment, the second base 81 is provided with a third slide 811, and the second support seat 82 is provided with a fourth slide 821. The support part includes two groups of symmetrically arranged second support assemblies 84, and the second support assembly 84 includes two support rods, a third support rod 841 and a fourth support rod 842, which are cross-arranged. The top end of the third support rod 841 is hinged to the second support seat 82, and the bottom end of the third support rod 841 can slide along the third slide 811. The bottom end of the fourth support rod 842 is hinged to the second base 81, and the top end of the fourth support rod 842 can slide along the fourth slide 821. The driving mechanism can act on the second support assembly 84 to change the angle between the third support rod 841 and the fourth support rod 842, thereby changing the height of the second support seat 82 from the second base 81.

[0107] When the driving component acts on the second supporting component 84 to reduce the angle between the third supporting rod 841 and the fourth supporting rod 842, the height of the second supporting component 84 increases, thereby driving the second supporting seat 82 to rise relative to the second base 81, and then lifting the supporting part 400 of the saddlebag upward to a preset height (original position), and the supporting part 400 can be rotationally driven by the rotating driving part. After the loading and unloading of the supporting part 400 is completed, the rotating driving device drives the supporting part 400 in reverse to rotate to the original position, and the driving component acts on the second supporting component 84 to increase the angle between the third supporting rod 841 and the fourth supporting rod 842, so that the height of the second supporting component 84 decreases, thereby driving the second supporting seat 82 to descend relative to the second base 81 to the supporting part 400 and cooperate with the end base frame 200, and then drive the end base frame 200 and the supporting part 400 to descend together and cooperate with the main body through the lifting device. Alternatively, in this embodiment, the second support assembly 84 can also be configured as a scissor fork or a retractable sleeve structure, and configuring the second support assembly 84 as two cross-shaped and relatively rotatable support rods can simplify the overall structure.

[0108] In the above embodiment, the driving mechanism includes a second driving member and a second locking assembly 832, and the second driving member is arranged on the second base 81 and provides a force source for dynamic lifting. Specifically, the second driving member can act on the second support assembly 84 to change the angle between the two support rods. When the angle between the two support rods reaches the minimum, that is, the second support seat 82 rises to the highest position, the second locking assembly 832 can lock the relative positions of the two support rods, that is, keep the state of the second support assembly 84 unchanged, so that the height position of the second support seat 82 is stable, and the second support seat 82 is prevented from falling due to sudden failure of the second driving member, thereby ensuring that the lifting device can provide stable support for the end frame 200 when in use.

[0109] Furthermore, the second locking assembly 832 includes a second push rod 833 and a second rocker 834, and the second base 81 is also provided with a second pin seat 812. Specifically, as shown in FIG. Fig.21 As shown, the second push rod 833 includes a third section 8331, a second bend 8333 and a fourth section 8332 which are arranged in sequence, wherein the second bend 8333 is hinged to the second driving member, the end of the third section 8331 is hinged to the bottom end of the third support rod 841 and can slide along the third slide 811, one end of the second rocker arm 834 is hinged to the end of the fourth section 8332, and the other end of the second rocker arm 834 is hinged to the second pin seat 812; the second driving member can act on the second bend 8333 and drive the second rocker arm 834 to rotate around the second pin seat 812, thereby driving the bottom end of the third support rod 841 to slide along the third slide 811, and when the angle between the two reaches the minimum, the second bend 8333 is located above the second pin seat 812.

[0110] In detail, the opening of the second bend 8333 is downward, the second rocker arm 834 is hinged between the fourth section 8332 and the second pin seat 812, the second driving member can act on the second bend 8333, and drive the second rocker arm 834 to rotate around the hinge point between it and the second pin seat 812, thereby driving the second push rod 833 to rotate around the hinge point between the second bend 8333 and the second driving member, and the third section 8331 can drive the fourth support rod 842 to move when rotating around the hinge point. Due to the limitation of the third slide 811, the bottom end of the third support rod 841 can only slide along the third slide 811 to achieve a change in the angle between the two support rods.

[0111] When the third support rod 741 slides along the third slide 711 to the minimum angle between the two support rods so that the second support seat 82 rises to the highest position, the second bend 8333 is just located above the second pin seat 812, and the second driving member no longer works. At this time, if the second driving member fails and its thrust is insufficient, the driving action of the second driving member on the second support assembly 84 is removed, and the support portion 400 continues to press down the second support seat 82, and the angle between the two support rods tends to increase. Since the opening of the second bend 8333 is downward and located directly above the second pin seat 812, at this time, the vertical downward pressure cannot move the second push rod 833 laterally, thereby limiting the rotation of the second rocker arm 834 and the sliding of the third support rod 841 along the third slide 811, thereby keeping the state of each second support assembly 84 unchanged, that is, the angle between the two support rods remains unchanged, the height of the second support seat 72 remains unchanged, and the stability is better.

[0112] By setting the above-mentioned locking device, when the second driving member raises the second support seat 82 to the highest position through the second support assembly 84, the second support assemblies 84 can be automatically locked. In this state, the vertical force cannot change the state of each second support assembly 84. Only when the second support seat 82 needs to be lowered, the second driving member provides a reverse force to make the second push rod 833 move horizontally until the second bend 8333 is disengaged from the second pin seat 812, which can achieve unlocking and drive the bottom end of the third support rod 841 to move in the opposite direction along the third slide 811 until the second support seat 82 drops to the lowest state (such as Fig.17 The second locking assembly 832 can achieve locking and unlocking while achieving the lifting and lowering of the second support seat 82, 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.

[0113] In the above embodiment, the end of the third section 8331 of the second push rod 833 is provided with a connecting shaft, and the connecting shaft sleeve is provided with a second roller 8335. Fig.18As shown, the second base 81 is further provided with a second rolling plate 813, and the second roller 8335 can roll along the second rolling plate 813. Specifically, the end of the third section 8331 may be provided with a groove, and the connecting shaft is provided between the two side walls of the groove. Alternatively, the second push rod 833 may also be provided with a structure including two second V-shaped connecting members 8334 arranged in parallel, and the above-mentioned connecting shaft is provided between the ends of the two second V-shaped connecting members 8334 facing the third section 8331, and the outer sleeve of the connecting shaft is provided with the second roller 8335 (such as Fig.21 shown).

[0114] When the second driving member acts on the second bend 8333 to rotate the second push rod 833 around the hinge point between the second bend 8333 and the second driving member, the end of the third section 8331 of the second push rod 833 can abut and roll with the second rolling plate of the second base 81 through the second roller 8335, so that when the lower end of the third support rod 841 slides along the third slideway 811, the second roller 8335 rolls along the second base 81, which reduces resistance and friction and wear between the third section 8331 and the second base 81, thereby ensuring service life. In addition, when the second rolling plate 813 is worn, it is replaced to ensure the service life of the second base 81.

[0115] In the above embodiment, if Fig. 22 As shown, the second rocker 834 is provided with a second concave notch 8341 at one end facing the second pin seat 812, and the two side walls of the second concave notch 8341 and the second pin seat 812 are respectively provided with second shaft holes 8342, and the second pin seat 812 is provided in the second concave notch 8341 and is rotatably connected via a pin shaft passing through the second shaft hole 8342. Alternatively, in this embodiment, one end of the second rocker 834 can also be provided at one side of the second pin seat 812 and connected via a pin shaft, and the second rocker 834 is provided with the second concave notch 8341 and the second pin seat 812 is located in the second concave notch 8341, so that the connection between the two can be more stable and avoid the occurrence of deflection and jamming.

[0116] In the above embodiment, the driving mechanism further includes a pusher 835, and the second driving member is a second hydraulic cylinder 831, wherein the pusher 835 includes a driving end 8351 and an action end 8352, the driving end 8351 is connected to the second piston rod 8311 of the second hydraulic cylinder 831, and the action end 8352 is provided with at least two push rods 8353, and each push rod 8353 is respectively hinged to the bottom end of the second bend (7333) of each second push rod 733. In other words, the number of push rods 8353 is the same as the number of support parts and driving wheels 87. When the number of driving wheels 87 is two, the two push rods 8353 of the action end 8352 of the second push rod 833 are in a U-shaped structure (such as Fig. 20As shown), each supporting part is driven to act simultaneously through the same second driving member and drives the second supporting seat 82 to rise and fall. Specifically, the number of the second hydraulic cylinders 831 can be one or two or more, and there is no specific limitation here. Each second hydraulic cylinder 831 can act on each second supporting assembly 84 at the same time through the pushing member 835 to ensure that each second supporting assembly 84 can be lifted synchronously with good stability.

[0117] Of course, in this embodiment, the second driving member can also be set as a motor, a gear and a rack or a motor, a screw and a nut, and no specific limitation is made here. The driving by the second hydraulic cylinder 831 can make the overall structure more stable.

[0118] In the above embodiment, the lifting device further includes a second upper sliding shaft 85 and a second roller sleeve 851 sleeved outside the second upper sliding shaft 85. The two sides of the second support seat 82 are connected to the second base 81 through the symmetrically arranged second support assembly 84. The second upper sliding shaft 85 passes through the top of the fourth support rod 842 of the symmetrically arranged second support assembly 84 and can slide along the third slideway 811. The second roller sleeve 851 is located between the two fourth support rods 842 and rolls against the second support seat 82. In other words, the second support assembly 84 and the second support seat 82 are acted on by the second roller sleeve 851 to ensure the supporting force between the second support assembly 84 and the second support seat 82, and the stability is good. At the same time, the second roller sleeve 851 is arranged between the two fourth support rods 842, and can also limit the two to avoid the change of the distance between the two to affect the lifting of the support part 400.

[0119] Furthermore, the lifting device further includes a second lower sliding shaft 86, which passes through the bottom end of the third support rod 841 of the symmetrically arranged second support assembly 84 and the third section 8331 of the second push rod 833, and can slide along the third slideway 811. The arrangement of the second lower sliding shaft 86 can realize that the bottom end of the third support rod 841 can slide along the third slideway 811, and the bottom end of the third support rod 841 is hinged to the end of the third section 8331 of the second push rod 833, which can simplify the overall structure.

[0120] Furthermore, Fig.23 As shown, the bottom ends of the third support rod 841 are respectively provided with second reinforcing sleeves 8411 sleeved outside the second lower sliding shaft 86. The second reinforcing sleeve 8411 can increase the structural strength of the bottom end of the third support rod 841, and can also limit the bottom end of the third support rod 841, reduce the distances between the two sides thereof and the second base 81 and the first end of the second push rod 833, avoid deflection, and have good stability.

[0121] In the above embodiment, the second base 81 and the second support base 82 are respectively provided with side panels, and the third slideway 811 and the fourth slideway 821 are both long holes provided on the side panels. Alternatively, in this embodiment, the third slideway 811 and the fourth slideway 821 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.

[0122] In the above embodiment, the rotating device 600 includes two sets of power wheel groups, which can drive the support part 400 to rotate to a preset angle from both ends, and each power wheel group includes a driving wheel 610 and a driven wheel 620 arranged at intervals on the bottom surface, wherein, Figure 3 As shown, the driving wheel 610 is arranged toward the side close to the track 100, that is, after the support portion 400 is rotated relative to the end chassis 200 around its rotation axis to a certain angle (the certain angle is less than the above-mentioned preset angle) by the driving wheel 87 arranged on the upper end surface of the second support seat 82, its outer side (the front side facing the rotation direction) can be rotated to cooperate with the driving wheel 610 (such as Figure 5 The driving wheel 610 can then continue to drive the support portion 400 to rotate around its rotation axis to above the driven wheel 620. Then, the support portion 400 will continue to rotate under the action of the driving wheel 610 until it is disengaged from the driving wheel 87, until it rotates to the above-mentioned preset angle to abut against the limit stopper 310 and connect with the ramp transition device 300 (as shown in FIG. Figure 6 When the support portion 400 rotates to disengage from the driving wheel 87, there is at least one driving wheel 610 and one driven wheel 620 underneath it, so as to ensure that during the rotation of the support portion 400, there are always at least two rollers (the driving wheel includes the driving wheel 610 and the driven wheel 620) supporting it from one end, so as to provide good stability.

[0123] Alternatively, in the present embodiment, there is no limitation on the specific structure of the rotating device 600, and it can be configured as a pushing device so as to push and pull the support portion 400 from both ends to rotate it around its rotation axis. The configuration of the driving wheel 610 and the driven wheel 620 can provide support to the support portion 400 from below while driving the support portion 400 to rotate. The center positioning device 500 does not need to be subjected to force or only bears a small force, thereby ensuring the stability of the overall structure.

[0124] Please refer to Figure 24-Figure 30 , Fig.24 is a schematic diagram of the structure of the longitudinal positioning device at the highest position; Fig.25 yes Fig.24 The main view; Fig.26 is a schematic diagram of the structure of the longitudinal positioning device in the lowest position; Fig. 27 yes Fig.26 The main view; Fig.28 It is a schematic diagram of the structure of the third base; Fig.29 is a schematic diagram of the structure of the third sliding seat; Fig.30 It is a partial structural schematic diagram of the longitudinal positioning device.

[0125] The station equipment system also includes a longitudinal positioning device 900 arranged in the track 100, and the longitudinal positioning device 900 includes a third base 91, a third sliding seat 92, a lifting part 94, a driving part and a positioning part 95, wherein the driving part can drive the third sliding seat 92 to slide longitudinally relative to the third base 91, the lifting part 94 and the positioning part 95 are both arranged on the third 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 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 third sliding seat 92 to slide longitudinally relative to the third base 91, and drive the positioning part 95 arranged on the third 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.

[0126] Among them, the longitudinal direction refers to the length direction of the saddlebag vehicle. The longitudinal positioning device 900 can drive the vehicle to move 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, the slope transition device 300 and the rotating device 600, etc.) arranged on the platform, thereby ensuring smooth loading and unloading of the vehicle.

[0127] 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 portion 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 supporting portion 400 is located within the preset range after the piggyback vehicle stops, the lifting portion 94 of the longitudinal positioning device 900 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 third sliding seat 92 drives the positioning portion 95 to move longitudinally until the positioning portion 95 and the lower end surface of the supporting portion 400 are positioned. The structure cooperates, and then 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 make it separate from the end frame 200, and then the supporting part 400 is driven by the rotating device 600 to rotate until it is connected with the slope transition device 300, and then the loading and unloading operation can be carried out.

[0128] 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 operation of the end chassis lifting device 700, the support part lifting device 800 and the rotating device 600. 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.

[0129] 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 support part 400 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 400 of the piggyback vehicle can be adjusted to reach the preset position by setting one or more groups of two longitudinal positioning devices 900 arranged opposite to each other in the longitudinal direction, which has better flexibility.

[0130] 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 third 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 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 third sliding seat 92 to drive the positioning portion 95 to slide to cooperate with the positioning structure. In the process, the positioning portion 95 is in a sliding state relative to the support portion 400. The setting of the third 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.

[0131] There is no specific limitation on the arrangement of the positioning block 952 and the positioning structure. Fig.30 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.

[0132] In the above embodiment, the lifting part 94 is an air spring disposed on the third 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 a 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.

[0133] Furthermore, the third 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 third 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.26 and Fig. 27 As shown), the setting of the swing member can ensure the stability of the positioning portion 95 while simplifying the overall structure.

[0134] 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 third 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.

[0135] In the above embodiment, the driving part includes a third hydraulic cylinder 93 hinged to the third base 91, and the end of the third piston rod 931 of the third hydraulic cylinder 93 is hinged to the positioning part 95. The third piston rod 931 of the third hydraulic cylinder 93 pushes and pulls the positioning part 95 so that the third sliding seat 92 and the positioning part 95 slide longitudinally as a whole. Alternatively, in this embodiment, the third piston rod 931 of the hydraulic rod can also act on the third sliding seat 92, that is, directly push and pull the third sliding seat 92 to drive the positioning part 95 to slide longitudinally. When the third piston rod 931 of the third hydraulic cylinder 93 is hinged to the positioning part 95, when the third piston rod 931 is in a retracted state, part of the third 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 third sliding seat 92 and the end of the third base 91, thereby reducing the overall volume of the longitudinal positioning device 900.

[0136] 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 third base 91 and directly act on the third sliding seat 92 to make it slide longitudinally relative to the third base 91. When the driving part is set to the third hydraulic cylinder 93, the overall structure can be simplified and the stability can be better.

[0137] 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.24 and Fig.25 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.

[0138] Specifically, the limiting portion 97 includes a first connecting rod 971 and a second connecting rod 972 which are hinged to each other. Fig.29 and Fig.30 As shown, the third 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 unfold 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.

[0139] 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.

[0140] In the above embodiment, if Fig.28 As shown, the third base 91 is provided with a fifth slideway 911 in the longitudinal direction, and the third sliding seat 92 is provided with a slider 922 capable of sliding along the fifth slideway 911. Specifically, as shown in FIG. Fig.29 and Fig.30 As shown, in this embodiment, the fifth slide 911 is a slide groove provided on the third 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 third sliding seat 92, or the slide groove can be provided on the upper end surface of the third base 91, and a slider 922 capable of sliding along the slide groove is provided on the lower end surface of the third sliding seat 92. Of course, in this embodiment, the fifth 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.

[0141] Of course, in this embodiment, the fifth slideway 911 can also be provided on the third sliding seat 92, and the third base 91 can slide along the fifth slideway 911. Since the third base 91 is fixed on the rail surface, the third sliding seat 92 can slide relative to the third base 91. When the fifth slideway 911 is provided on the third base 91, the sliding continuity of the third sliding seat 92 can be ensured to be good.

[0142] In addition, in this embodiment, the hinged connections between the above-mentioned components can be connected by pins or round pins, and the pins or round pins are limited by washers and cotter pins.

[0143] 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.
