[0002] The mid-axle vehicle transport train is a special train used to transport commercial vehicles. It consists of a front car and a rear car. The front car includes a front frame and a front platform, and the rear car includes a rear frame and a rear platform. In order to ensure that the platform of the vehicle transport vehicle can safely and smoothly load and unload vehicles, a front lifting device is provided between the front frame and the front platform, and a rear lifting device is provided between the rear frame and the rear platform. The platform is raised and lowered by hydraulic drive.

[0003] During the loading process of the front vehicle, the commercial vehicle drives from the rear frame to the front frame, the front lifting device is adjusted to make its rear end tilt downward, the rear lifting device is adjusted to make the rear end of the rear platform tilt downward and the front end of the rear platform butt against the rear end of the front platform, and the commercial vehicle drives from the rear platform to the front platform of the front vehicle, which takes a long time and has poor loading efficiency.

[0004] In addition, the existing front or rear vehicles mainly weld a set of wide columns on the frame, the columns have a C-shaped cross section, and a hydraulic cylinder is arranged inside the column. The lower part of the cylinder is hinged to the column, and the upper part of the cylinder is connected to a slider built into the column, and the slider is hinged to the platform. The hydraulic cylinder is extended and retracted to drive the slider to slide inside the column, thereby realizing the function of raising and lowering the platform. Although the existing platform lifting device can realize the function of raising and lowering the platform, since the cylinder is built into the column, the cylinder is inconvenient to install, the overall structure is complex and bulky, and the material used is large, and the economy is poor.

[0005] Therefore, how to provide a vehicle transporter with a simple structure, convenient loading and good economy is a technical problem that needs to be solved by those skilled in the art. Summary of the invention

[0006] The object of the present invention is to provide a vehicle transport vehicle which has a simple structure and is convenient for loading, can effectively improve the loading efficiency and has good economy.

[0007] In order to solve the above technical problems, the present invention provides a vehicle transport vehicle, which includes a front vehicle, a rear vehicle and a coupler device for connecting the front vehicle and the rear vehicle; the front vehicle includes a front frame, a front platform located above the front frame, a column assembly and two groups of front lifting devices symmetrically arranged on the left and right sides of the front frame, the column assembly and the front lifting device are both located between the front frame and the front platform, and are used to support the front platform, the column assembly is located at the front end of the front vehicle, and the front lifting device is located at the rear side of the front vehicle; the rear vehicle includes a rear frame, a rear platform located above the rear frame and a rear lifting device, the The rear platform includes a first platform and a second platform that are pivotally connected, the pivot axes of the first platform and the second platform are arranged along the width direction of the vehicle transport vehicle, and two groups of rear lifting devices symmetrically arranged on the left and right sides of the rear frame are respectively arranged between the first platform and the rear frame, between the second platform and the rear frame, and between the middle part of the rear platform and the rear frame. The rear lifting device can lift the rear platform so that the front end of the first platform is docked with the front frame or the front platform; the coupler device includes a first coupling member arranged at the rear end of the front frame and a second coupling member arranged at the front end of the rear frame.

[0008] The rear height of the front vehicle is adjusted by the front lifting device, and the height of the first platform and the second platform of the rear vehicle is adjusted by the rear lifting device. The specific loading process of the vehicle transporter is as follows:

[0009] (1) When loading the front platform, adjust the front lifting device to make the rear side of the front platform tilt downward, and adjust the rear lifting devices to make the front end of the first platform dock with the rear end of the front platform. The rear platform as a whole is tilted downward from front to rear. At this time, the commodity vehicle can drive from the rear end of the second platform to the first platform and then to the front platform until the front platform is loaded. Then adjust the front lifting device to lift the rear side of the front platform to an appropriate height.

[0010] (2) When loading the front frame, the position of the second platform remains unchanged. Only the rear lifting device connected to the first platform needs to be adjusted so that the front end of the first platform is butted against the rear end of the front frame. At this time, the rear platform is generally high in the middle and low at both ends. The commercial vehicle can enter from the rear end of the second platform, pass through the first platform, and then to the front frame until the front platform is loaded;

[0037] An embodiment of the present invention provides a vehicle transport vehicle, such as Figure 1 As shown, the vehicle transporter includes a front vehicle, a rear vehicle and a coupling device for connecting the front vehicle and the rear vehicle.

[0038] Specifically, Figure 4 As shown, the front vehicle includes a front vehicle frame 1, a front platform 2, a column assembly 6 and a front lifting device 7, wherein the front platform 2 is located above the front vehicle frame 1, the column assembly 6 and the front lifting device 7 are respectively located between the front vehicle frame 1 and the front platform 2, and are used to support the front platform 2, the column assembly 6 is provided at the front end of the front vehicle, and is used to support the front end of the front platform 2, and the front lifting device 7 is located at the rear side of the front vehicle, and is used to adjust the rear side height of the front platform 2. Figure 7 As shown, the rear vehicle includes a rear frame 3, a rear platform 4 and a rear lifting device 8, wherein the rear platform 4 is located above the rear frame 3, and the rear platform 4 includes a first platform 41 and a second platform 42 that are pivotally connected, and the pivot axis between the first platform 41 and the second platform 42 is arranged along the width direction of the vehicle transport vehicle, and the first platform 41 is arranged toward the front vehicle, and two groups of rear lifting devices 8 symmetrically arranged on the left and right sides of the rear frame 3 are respectively arranged between the first platform 41 and the rear frame 3, between the second platform 42 and the rear frame 3, and between the middle part of the rear platform 4 and the rear frame 3, that is, there are two groups of rear lifting devices 8 in total, and the rear lifting devices 8 can lift the rear platform 4 so that the front end of the first platform 41 is docked with the front frame 1 or the front platform 2.

[0039] A rear lifting device 8 is provided between the middle part of the rear platform 4 and the rear frame 3, wherein the middle part of the rear platform 4 refers to the position between the front end of the first platform 41 and the rear end of the second platform 42, and is not the exact middle position in a strict sense. The top end of the rear lifting device 8 here can be connected to the rear part of the first platform 41 or to the front part of the second platform 42, and is not specifically limited here.

[0040] The rear height of the front vehicle is adjusted by the front lifting device 7, and the height of the first platform 41 and the second platform 42 of the rear vehicle is adjusted by the rear lifting device 8. The specific loading process of the vehicle transport vehicle is as follows:

[0041] (1) Loading on front platform 2, such as Figure 2 As shown, by adjusting the front lifting device 7, the rear side of the front platform 2 is tilted downward, and by adjusting the rear lifting devices 8, the front end of the first platform 41 is docked with the rear end of the front platform 2. The rear platform 4 is in a structure that tilts downward from front to rear. At this time, the commodity vehicle 13 can drive from the rear end of the second platform 42 to the first platform 41 to the front platform 2 until the front platform 2 is loaded. Then, the front lifting device 7 is adjusted to lift the rear side of the front platform 2 to an appropriate height.

[0042] (2) When the front frame 1 is loaded, the position of the second platform 42 remains unchanged. It is only necessary to adjust the rear lifting device 8 connected to the first platform 41 so that the front end of the first platform 41 is butted against the rear end of the front frame 1. Figure 3As shown, at this time, the rear platform 4 is overall a structure with a high middle portion and low ends, and the commodity vehicle 13 can drive in from the rear end of the second platform 42 through the first platform 41 to the front frame 1 until the front platform 2 completes loading;

[0043] (3) The rear platform 4 is loaded, the rear lifting device 8 does not move, and the commodity vehicle 13 directly enters the rear platform 4 from the rear end of the second platform 42 until the rear platform 4 is loaded, and each set of the rear lifting device 8 is adjusted to raise the rear platform 4 to an appropriate position;

[0044] (4) The rear frame 3 is loaded, and finally the commercial vehicle 13 enters from the rear end of the rear frame 3 until the rear frame 3 is completely loaded.

[0045] It can be clearly seen from the above loading steps that the commodity vehicle 13 passes through the rear platform 4 and enters the front platform 2 and the front frame 1 of the front vehicle. During this process, the rear lifting device 8 of the rear vehicle is adjusted less frequently, which can simplify the overall vehicle operation process and effectively improve the loading efficiency. At the same time, the rear platform 4 of the rear vehicle is divided into a first platform 41 and a second platform 42, wherein the first platform 41 and the second platform 42 can pivot under the action of the rear lifting device 8, with a simple structure and good flexibility, so that the front end of the first platform 41 can better dock with the rear end of the front platform 2 or the front frame 1, so that the commodity vehicle 13 can be moved from the rear platform 4 to the front platform 2 and the front frame 1, and the installation is convenient.

[0046] The coupler device includes two coupling parts, a first coupling part 51 and a second coupling part 52, wherein the first coupling part 51 is arranged at the rear end of the front frame 1, and the second coupling part 52 is arranged at the front end of the rear frame 3. During the transportation of the vehicles, the front vehicle and the rear vehicle are connected through the coupling action of the two coupling parts, thereby realizing the towing of the rear vehicle by the front vehicle. Specifically, there is no restriction on the specific structure of the coupling parts. It is a well-known prior art for those skilled in the art to realize the connection between the front vehicle and the rear vehicle through the coupling action of the two coupling parts, and it will not be described here for the sake of saving space.

[0047] In the above embodiment, the rear platform includes a first platform 41 and a second platform 42. In this embodiment, the rear platform 4 can be divided into more parts, and at least one third platform (not shown in the figure) is provided between the first platform 41 and the second platform 42. In this embodiment, there is no limit on the number of the third platforms. The connection between the third platform and the first platform 41 and the second platform 42 and the connection between two adjacent third platforms are all pivotable connections, and the above-mentioned rear lifting device 8 is provided between each third platform and the rear frame 3, respectively, which has good flexibility.

[0048] The rear end of the front frame 1 is also provided with a flap 9 and a flap cylinder 10. The flap 9 is pivotally connected to the front frame 1, and the pivot axis of the flap 9 is arranged along the width direction of the vehicle transporter. The flap 9 can rotate around its pivot axis under the drive of the flap cylinder 10 and dock with the front end of the first platform 41. Figure 3 As shown, when the front frame 1 is loaded, the front end of the first platform 41 tilts downward. At this time, the flap 9 is driven to rotate by the flap cylinder 10 so that its rear end is docked with the front end of the first platform 41. The setting of the flap 9 facilitates the docking between the front frame 1 and the first platform 41, so that the commercial vehicle 13 can smoothly drive into the front frame 1 from the rear platform 4.

[0049] In the above embodiment, the front end of the first platform 41 is also provided with a retractable ferry 11 and a ferry driving member (not shown in the figure), and the ferry 11 can be retracted along the length direction of the vehicle transport vehicle under the action of the ferry driving member. Figure 2 and Figure 3 As shown, when loading the front vehicle, the ferry board driving member drives the ferry board 11 to extend toward the front vehicle, making it easier to dock with the front platform 2 or the front vehicle frame 1 (flap 9), so that the commodity vehicle 13 can smoothly drive into the front platform 2 or the front vehicle frame 1 from the rear platform 4. Specifically, the structures of the ferry board 11 and the ferry board driving member are not limited, as long as the ferry board 11 can extend outward along the front end of the first platform 41 and can be retracted inward under the action of the ferry board driving member.

[0050] In the above embodiment, the front lifting device 7 includes a front cylinder 71 and a support rod 72. One end of the front cylinder 71 is hinged to the front frame 1, and the other end is hinged to the middle of the support rod 72. The bottom end of the support rod 72 is hinged to the front frame 1. A slider 74 is provided at the top of the support rod 72. A slideway 73 is provided on the side beam of the front platform 2. The slider 74 can slide along the slideway 73. The front cylinder 71 can push the support rod 72 to rotate around its bottom end to change the angle between the length direction of the support rod 72 and the horizontal direction. Among them, the front cylinder 71 is hinged to the middle part of the support rod 72. The "middle" refers to the position between the top and the bottom of the support rod 72, not the middle position in a strict sense. Figure 6 As shown, when the angle between the length direction of the support rod 72 and the horizontal direction increases, the rear side of the front platform 2 rises, and when the angle between the length direction of the support rod 72 and the horizontal direction decreases, the rear side of the front platform 2 drops.

[0051] Specifically, when the front oil cylinder 71 pushes the support rod 72 upward, the support rod 72 rotates around its bottom end to increase the angle between it and the horizontal direction, and the top end of the support rod 72 drives the slider 74 to slide along the slideway 73, and the height of the top end increases to lift the front platform 2 until the rear part of the front platform 2 rises to the required height, and the front lifting device 7 is in the unfolded state. At this time, the support rod 72 and the front oil cylinder 71 form a "human" structure, so that the front platform 2 is in a stable position. Similarly, when the front oil cylinder 71 pulls the support rod 72 downward, the support rod 72 rotates around its bottom end to reduce the angle between its length direction and the horizontal direction, and the top end of the support rod 72 drives the slider 74 to slide in the opposite direction along the slideway 73, and the height of the top end decreases to pull down the rear side of the front platform 2 until the rear part of the front platform 2 drops to the lowest position, and the front lifting device 7 is in the folded state.

[0052] Two sets of front lifting devices 7 are arranged between the front frame 1 and the front platform 2, and are symmetrically located on the left and right sides of the vehicle transporter in the direction of travel, wherein the left and right sides refer to the two sides in the width direction of the vehicle transporter, so as to stably realize the lifting and lowering of the front platform 2. There is no need to set a wide column 61 structure, which can effectively reduce the dead weight of the whole vehicle and improve economic benefits. At the same time, the appearance is simple, smooth and has an aesthetic effect.

[0053] In the above embodiment, the front lifting device 7 also includes a first locking pin, and the slide 73 is also provided with a plurality of first locking holes adapted to the first locking pin, each first locking hole being arranged at intervals along the length direction of the slide 73, and the first locking pin can pass through the first locking hole and abut against the rear end of the slider 74. When the front platform 2 is lowered, the support rod 72 drives the slider 74 to slide from the back to the front along the slide 73. When the front platform 2 is lowered, the support rod 72 drives the slider 74 to slide from the front to the back along the slide 73. Therefore, the rear end of the slider 74 refers to the moving direction of the slider 74 driven by the support rod 72 when the front platform 2 is lowered. Therefore, the first locking pin can limit the slider 74 from sliding along the slide 73 toward the direction of the front platform 2 descending, thereby locking the state of the front lifting device 7, ensuring the stability of the state of the front platform 2, and preventing the rear side of the front platform 2 from descending due to external force or failure of the front cylinder 71 during the transportation of the vehicle.

[0054] The movement of the slider 74 is limited by the first locking pin and the first locking hole provided in the slide. The slider 74 can be limited without affecting the strength of the slide to ensure that the front platform 2 is in a stable position and avoid the rear side from falling. The structure is simple and the operation is convenient.

[0055] In the above embodiment, if Figure 8As shown, the rear lifting device 8 includes a rear cylinder 81, a telescopic assembly and a second locking pin. One end of the telescopic assembly is connected to the rear frame 3, and the other end is connected to the rear platform 4. Specifically, the telescopic assembly includes a sliding member 82 and an outer sleeve 83 sleeved on the outer side of the sliding member 82. The sliding member 82 and the outer sleeve 83 can slide relative to each other along the length direction under the action of the rear cylinder 81, and the sliding member 82 is provided with a plurality of second locking holes at intervals along its length direction. The inner end of the outer sleeve 83 is an abutting end, and the second locking pin can pass through the second locking hole and abut against the abutting end.

[0056] Through the pushing action of the rear oil cylinder 81, the sliding member 82 and the outer sleeve 83 slide relative to each other, so that the length direction of the telescopic assembly between the rear frame 3 and the rear platform 4 increases, and the rear platform 4 rises. When the rear lifting device 8 is used to lift the rear platform 4 to the desired position, the second locking pin is passed through the second locking hole of the sliding member 82 close to the abutting end, so that the second locking pin abuts against the abutting end to limit the relative sliding between the sliding member 82 and the outer sleeve 83. At this time, the length of the telescopic assembly is locked, and the rear platform 4 is in a stable position; similarly, when the second locking pin is withdrawn from the second locking hole, the locking effect is released. Under the pulling action of the rear oil cylinder 81, the sliding member 82 and the outer sleeve 83 slide relative to each other, so that the length of the telescopic assembly between the rear frame 3 and the rear platform 4 decreases, and the rear platform 4 drops to the lowest position.

[0057] Among them, the second locking pin is used to lock the relative position between the sliding member 82 and the outer sleeve 83, so that the positions of the two in the length direction are fixed, that is, the length of the telescopic assembly is fixed, and then the state of the rear lifting device 8 is locked to ensure the stability of the state of the rear platform 4, and to prevent the rear platform 4 from being lowered due to external force or failure of the rear cylinder 81 during the transportation of the vehicle. Since the rear platform 4 is used to place the commodity vehicle 13, the force on each rear lifting device 8 is relatively large, so the force between the second locking pin and the abutting end is relatively large. In this embodiment, the abutting end is also provided with a reinforcement structure to ensure the strength of the abutting end, avoid the abutting end from being damaged due to the large force, and ensure transportation safety.

[0058] In the above embodiment, the rear vehicle further includes two sets of limit frames 12 symmetrically arranged on the left and right sides of the rear frame 3, the top of the limit frame 12 is rotatably connected to the middle of the rear platform 4, the bottom of the limit frame 12 is rotatably connected to the rear frame 3, and the rotation direction of the limit frame 12 is the length direction of the vehicle transport vehicle. In other words, the rotation direction of the limit frame 12 is the front and rear direction of the vehicle body, which will not interfere with the lifting and lowering of the rear platform 4, and at the same time, the left and right directions of the rear platform 4 can be limited to ensure the stability of the rear platform 4 and avoid the situation of left and right tipping.

[0059] In the above embodiment, if Figure 5As shown, the column assembly 6 includes a column 61, a column cylinder 62 and a sleeve 63. The sleeve 63 is slidably sleeved on the outer side of the column 61. The bottom end of the column 61 is fixedly connected to the front frame 1. The sleeve 63 is hinged to the front end of the front platform 2. The column cylinder 62 is used to push the sleeve 63 to slide along the length direction of the column 61. The sleeve 63 is slidably sleeved on the column 61. The sleeve 63 is driven to slide along the length direction of the column 61 by the push rod of the column cylinder 62. The front end of the front platform 2 is hinged to the sleeve 63. In this way, in the process of the sleeve 63 sliding along the length direction of the column 61, the front end of the front platform 2 moves up and down with the sleeve 63, thereby realizing the lifting operation of the front platform 2. The connection structure between the front end of the front platform 2 and the column 61 is simple and reliable, and easy to install.

[0060] In the above embodiment, the column assembly 6 further includes a third locking pin, and the column 61 is provided with a third locking hole 64, and the third locking pin can pass through the third locking hole 64 and abut against the bottom end of the sliding sleeve 63. After the sliding sleeve 63 is moved to a desired position by the column oil cylinder 62, the state of the column assembly 6 can be locked by passing the third locking pin through the third locking hole 64 adjacent to the bottom end of the sliding sleeve 63, so that the front end position of the front platform 2 is stable. When the third locking pin is withdrawn from the third locking hole 64, the locking effect is released, and under the action of the column oil cylinder 62, the sliding sleeve 63 can slide along the length direction of the column 61 to adjust the front end height of the front platform 2.

[0061] 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.
