The cylinder 10 can drive the conveyor The moving rod 5 connected to the end moves, and at the same time, the rack 8 on the moving rod 5 drives the No. 1 gear 9 to rotate. The No. 1 gear 9 can drive the other rack 8 to move in the opposite direction, and the rack 8 drives the other moving rod 5 to move in the opposite direction, so that the two moving rods 5 simultaneously drive the two splints 7 to move in opposite directions through the connecting block 6, that is, drive the splints 7 to the two sides of the cargo to clamp the two sides of the cargo to limit it. When it is transported to the designated position, the output end of the cylinder 10 drives the splint 7 away from the cargo through the moving rod 5 and the connecting block 6 to release the limit, and people can take the cargo out of the trailer 1.

[0022] The inner side of the support frame 3 is symmetrically fixedly connected with a slide rail 11, the outer wall of the slide rail 11 is slidably connected to the back side of the sliding plate 4, and the top of the sliding plate 4 is provided with a lifting mechanism, and the lifting mechanism includes a rotating motor 12 and a screw rod 13. The top of the sliding plate 4 is fixedly installed with a rotating motor 12, and the top of the rotating motor 12 is rotatably connected with the screw rod 13.

By measuring the time difference from laser emission to reception, the distance between the AGV body 18 and the surrounding objects is calculated. The AGV body 18 converts the path planning result into a motion instruction, and transmits the motion instruction to the self-locking motor 17 through the control system. The output end of the self-locking motor 17 drives the third gear 16 to rotate. The third gear 16 is engaged with the second gear 15, and the third gear 16 is connected to the rotating wheel 2 through the rotating frame 14. It can drive the rotating wheel 2 to rotate with the second gear 15 as the center, so as to automatically reverse when the trailer 1 moves.
