The main body 1 is rotated, and the roller 18 on the main body 1 facilitates the rotation of the transmission rod 4 on the main body 1. When the transmission rod 4 rotates, it passes through the arc groove and the threaded groove on the transmission rod 4, thereby driving the support frame 2 to move on the main body 1 as the transmission rod 4 rotates. At this time, as the support frame 2 moves, the pulley 16 will slide in the slideway 7. Through the combination of the pulley 16 and the slideway 7, the stability of the movement of the support frame 2 on the main body 1 is improved, so that the goods are moved to the target vehicle, avoiding manual handling, and different lifting devices can be installed through the hanging ring 3 on the support frame 2, avoiding the user from spending time looking for a fixed lifting device, and the length of the main body 1 is the same as that of the vehicle, which is convenient for the user to move to different target positions according to different needs at any time when the support frame 2 moves.

[0030] Embodiment 2, as Figure 1-7As shown, the left and right ends of the fixed block 10 are fixedly connected with a support rod 12, and the end of the support rod 12 away from the fixed block 10 is fixedly connected with a baffle 13, the outer circumferential surface of the support rod 12 is slidably connected with a sleeve 11, and a sliding groove 14 is provided at the connection between the sleeve 11 and the baffle 13, and a threaded hole 15 is provided inside the end of the sleeve 11 away from the support rod 12, and placement grooves 19 are provided on both sides of the outer surface of the lower end of the support frame 2, and the inner surfaces of both sides of the placement groove 19 are rotatably connected with a rotating shaft 17 near the lower end, and the end of the rotating shaft 17 away from the support frame 2 is fixedly connected with a pulley 16, and the blocks 8 on the two adjacent main bodies 1 correspond to each other with the slots 9. At this time, the connecting rods 5 between the adjacent main bodies 1 correspond to each other, take out the fixed block 10, and rotate the two sleeves 11 on the fixed block 10 so that the two sleeves 11 The threaded holes 15 on the main body 1 are threadedly connected with the two adjacent connecting rods 5, and as the sleeve 11 is connected to the connecting rod 5, the baffle 13 on the support rod 12 will be driven to slide in the slide groove 14 until the baffle 13 is in close contact with the inner surface of the sleeve 11, and as the sleeve 11 is fixed, the blocks 8 and the card grooves 9 on the two adjacent main bodies 1 will be driven to be connected with each other until the fixation is completed. According to the length of the target vehicle, the length of the main body 1 is paved to the length of the two vehicles. At this time, the support frame 2 is installed on the main body 1. When installing the support frame 2, the pulley 16 on the support frame 2 is made to correspond to the slideways 7 on the main bodies 1 on both sides of the vehicle. At this time, the arc groove on the support frame 2 can be made to be in close contact with the transmission rod 4, thereby completing the overall installation. The present invention occupies a small area and is easy to disassemble and assemble, thereby improving work efficiency and ensuring the loading capacity of the vehicle.

[0031] Working principle: When using the device, first bring the two trucks that need to be loaded and unloaded together close to each other, then multiple main bodies 1 can be installed on the edge of the car body, and when installing, take out two adjacent main bodies 1, so that the card blocks 8 and the card slots 9 on the two adjacent main bodies 1 correspond to each other, and the connecting rods 5 between the adjacent main bodies 1 correspond to each other, take out the fixing block 10, rotate the two sleeves 11 on the fixing block 10, so that the threaded holes 15 on the two sleeves 11 are threadedly connected with the two adjacent connecting rods 5, and as the sleeves 11 and the connecting rods 5 are connected, the threaded holes 15 on the two sleeves 11 are threadedly connected with the two adjacent connecting rods 5. The connection of the rod 5 will drive the baffle 13 on the support rod 12 to slide in the slide groove 14 until the baffle 13 is in close contact with the inner surface of the sleeve 11, and as the sleeve 11 is fixed, the blocks 8 and the slots 9 on the two adjacent main bodies 1 are connected to each other until the fixation is completed. According to the length of the target vehicle, the length of the main body 1 is laid to the length of two vehicles. At this time, the support frame 2 is installed on the main body 1. When installing the support frame 2, the pulley 16 on the support frame 2 corresponds to the slideway 7 on the main body 1 on both sides of the vehicle. At this time, the support frame 2 can be made to correspond to each other. The arc groove on the frame 2 and the transmission rod 4 are in close contact with each other, thereby completing the overall installation. The present invention occupies a small area and is easy to disassemble and assemble, thereby improving work efficiency and ensuring the loading capacity of the vehicle. When in use, the motor 6 is first started, and the transmission rod 4 is driven by the motor 6 to rotate on the main body 1. The roller 18 on the main body 1 facilitates the rotation of the transmission rod 4 on the main body 1. When the transmission rod 4 rotates, it passes through the arc groove and the threaded groove on the transmission rod 4, thereby driving the support frame 2 to move on the main body 1 as the transmission rod 4 rotates, and at this time, as the transmission rod 4 rotates, the support frame 2 is driven to move on the main body 1. As the support frame 2 moves, the pulley 16 will slide in the slideway 7. The combination of the pulley 16 and the slideway 7 improves the stability of the support frame 2 on the main body 1, so that the goods can be moved to the target vehicle, avoiding manual handling. In addition, different lifting devices can be installed through the hanging ring 3 on the support frame 2, avoiding the user from spending time looking for a fixed lifting device. The length of the main body 1 is the same as that of the vehicle, which makes it convenient for the user to move to different target positions at any time according to different needs when the support frame 2 is moved.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
