Two cavities 6 which are symmetrically arranged are arranged in the chassis 1. A delivery assembly is provided on the upper end surface of the chassis 1. The delivery assembly includes a support block arranged on the side wall of the long railing 2. A rotating motor 12 is provided on the upper end surface of the support block. The rotating motor 12 is a prior art. A staff can rotate an object connected thereto by opening the rotating motor 12. A cross bar 13 is fixedly connected to the motor shaft of the rotating motor 12. A telescopic motor 14 is provided on one end of the cross bar 13. The telescopic motor 14 is a prior art. A staff can move an object connected to its motor shaft by opening the telescopic motor 14. The telescopic motor 14 is made of anti-corrosion material. The telescopic motor 14 has been subjected to wind erosion. The anti-corrosion property of the anti-corrosion material can reduce the damage to the telescopic motor 14 and extend the service life of the device.

[0022] The motor shaft of the telescopic motor 14 is fixedly connected with a lifting rod 15, and the lower end of the lifting rod 15 is fixedly connected with a supporting platform 25. The lower end of the lifting rod 15 is fixedly connected with a stabilizing rod 16. A sliding mouth 17 is provided in the stabilizing rod 16. Two sliding blocks 24 symmetrically arranged are slidably connected in the sliding mouth 17. One end of the two sliding blocks 24 is threaded with a screw 18, and the ends of the two screws 18 close to each other are fixedly connected, and the ends of the two screws 18 away from each other are penetrated by the stabilizing rod 16. A knob 22 is provided on one end of the screw 18. By rotating the knob 22, the staff can easily rotate the screw 18, thereby driving the two clamping blocks 19 to move. The ends of the two sliding blocks 24 away from the stabilizing rod 16 are both provided with clamping blocks 19. Through the above structure, the staff can place heavy objects on the supporting platform 25, and then drive the screw 18 to rotate by rotating the knob 22, thereby driving the clamping blocks 19 to move relatively, clamping heavy objects of different specifications, and sending them into the car through the telescopic motor 14;

[0023] A protective layer is provided on one side wall where the two clamping blocks 19 are close to each other. Through the protective effect of the protective layer, when the clamping blocks 19 clamp the heavy objects, the damage to the heavy objects by the clamping blocks 19 can be reduced. Two guardrail fixing components; the guardrail fixing components include two notches 3 respectively arranged on one end of the two long guardrails 2, and the two notches 3 are slidably connected with fixing blocks 4, and one end of the two fixing blocks 4 is threadedly penetrated with threaded rods 5, and one end of the two threaded rods 5 is respectively rotatably connected in the two notches 3, and the other ends of the two threaded rods 5 are respectively rotatably penetrated in the cavity 6, and one end of the two threaded rods 5 is fixedly connected with a transverse gear 11, a platform 7 is provided on the side wall of the chassis 1, and a rotating motor 8 is provided on the platform 7. A protective box body 20 is provided on the upper end surface of the platform 7, and the rotating motor 8 is arranged in the protective box body 20. Through the setting of the protective box body 20, the erosion damage of the rotating motor 8 by wind dust can be reduced, and the service life of the device can be extended;

[0024] The motor shaft of the rotating motor 8 is fixedly connected with a rotating rod 9, and the other end of the rotating rod 9 is rotatably connected in the cavity 6. The rotating rod 9 is rotatably connected in the cavity 6. Two vertical gears 10 are fixedly connected to the rotating rod 9. The two vertical gears 10 are respectively meshed with two horizontal gears 11. The rotation of the rotating rod 9 drives the two vertical gears 10 to rotate, thereby rotating the two horizontal gears 11 meshed therewith, thereby driving the two threaded rods 5 fixedly connected thereto to rotate, thereby driving the fixed block 4 to move, and then completing the rising and falling work of the side fence 21. The two fixed The end of the block 4 away from the two slots 3 is fixedly connected with a side fence 21. The lower ends of the two side fences 21 are provided with a plurality of shock-absorbing feet 23. When the side fences 21 are descending, they will touch the ground. At this time, the lower ends of the side fences 21 will collide with the ground and cause damage. By providing a plurality of shock-absorbing feet 23, the side fences 21 can be prevented from colliding with the ground and causing damage. Through the setting of the above structure, the staff can turn on the rotating motor 8, thereby easily driving the two side fences 21 to rise and fall without manual buckling, saving manpower and improving work efficiency.

[0025] The detailed working process of the utility model is as follows:

[0026] The staff first drives the semi-trailer to a suitable position and stops it. At this time, the staff can turn on the rotating motor 8, and drive the rotating rod 9 to rotate by the rotating motor 8, so that the two vertical gears 10 on the rotating rod 9 rotate, and the rotation of the two vertical gears 10 drives the rotation of the two horizontal gears 11, thereby driving the two threaded rods 5 connected to the two horizontal gears 11 to rotate, so that the two fixed blocks 4 are lowered, thereby driving the side fence 21 to descend until the shock-absorbing pad 23 touches the ground. At this time, the staff can turn on the rotating motor 12 to rotate the cross bar 13 to the specified position, and then turn on the telescopic motor 14 to drive the lifting rod 15 descends to the specified position, and then the staff can put the weight on the support platform 25, and then rotate the knob 22 to drive the screw 18 to rotate, so that the two clamping blocks 19 move relative to each other until the weight is clamped, and then the telescopic motor 14 can be opened in reverse to make it clamp the weight and rise, and then adjust the rotating motor 12 to rotate the weight into the car. At this time, the staff can rotate the knob 22 in the reverse direction and take out the weight, and repeat the above operation many times until all the weights are delivered, and then the staff can turn on the rotating motor 8 in the reverse direction to make the two side fences 21 rise to the specified position, completing the rising and fixing of the side fences 21.
