The loading and unloading efficiency, safety, and adaptability of goods directly affect the operating cost and flow efficiency of the entire logistics chain. As a core auxiliary loading and unloading device for material transport vehicles, the hydraulic lifting tailgate drives the load-bearing platform through a hydraulic transmission system to achieve lifting, tilting, and other actions. It can directly lift goods from the ground to the inside of the vehicle or unload them from the vehicle to the ground without relying on external loading and unloading equipment, greatly improving the flexibility and efficiency of loading and unloading operations. It has become one of the standard components of modern material transport vehicles.

[0015] Example 1 like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a hydraulic lifting tailgate for a material transport vehicle includes a first placement tailgate 1. A hollow bracket 2 is fixed to the lower surface of the first placement tailgate 1. A first bearing 3 is provided on the side wall of the hollow bracket 2. A hand handle 4 is provided on the inner side of the first bearing 3. A first bevel gear 5 is fixed to the end of the hand handle 4. A second bevel gear 6 is meshed with one side of the first bevel gear 5. A connecting column 7 is fixed inside the second bevel gear 6. A threaded column 8 is fixed to the top of the connecting column 7. A second bearing 9 is provided on the outer periphery of the other left end of the threaded column 8. A threaded plate 10 is threadedly connected to the outer periphery of the threaded column 8. A movable plate 12 is provided on one side of the threaded plate 10. A first rotating shaft 11 is provided at the connection between the threaded plate 10 and the movable plate 12. A push plate 14 is provided at the other end of the movable plate 12. A second rotating shaft 13 is provided at the connection between the movable plate 12 and the push plate 14. A second placement tailgate 15 is fixed to the side wall of the push plate 14.

[0016] The hand crank 4 forms a rotating structure with the hollow bracket 2 via the first bearing 3, and forms a fixed structure with the first bevel gear 5. The first bevel gear 5 and the second bevel gear 6 form a meshing structure. The second bevel gear 6 forms a fixed structure with the threaded column 8 via the connecting column 7. When the hand crank 4 is rotated by external force, the first bevel gear 5 can be driven to rotate. Through the meshing structure of the first bevel gear 5 and the second bevel gear 6, the rotation of the first bevel gear 5 can cause the second bevel gear 6 to rotate, which indirectly drives the threaded column 8 to rotate.

[0017] The threaded column 8 and the threaded plate 10 form a threaded connection. The threaded plate 10 forms a rotating structure with the movable plate 12 through the first rotating shaft 11. The movable plate 12 forms a rotating structure with the push plate 14 through the second rotating shaft 13. Through the threaded connection between the threaded column 8 and the threaded plate 10, the rotation of the threaded column 8 can move the threaded plate 10. The movement of the threaded plate 10 can move the movable plate 12. The movement of the movable plate 12 can drive the push plate 14 to move, thereby driving the second placement tail plate 15 to move, which facilitates the placement and retraction of the second placement tail plate 15 and adjusts the usable area.

[0018] Example 2 Unlike Embodiment 1, the lower side of the first placement tail plate 1 is provided with an arc-shaped support plate 17, a third rotating shaft 16 is provided at the connection between the first placement tail plate 1 and the arc-shaped support plate 17, and an installation plate 19 is provided at the other end of the arc-shaped support plate 17.

[0019] A fourth pivot 18 is provided at the connection between the arc-shaped support plate 17 and the mounting plate 19. A fixed cylindrical frame 20 is fixed to the end side wall of the arc-shaped support plate 17. A fifth pivot 21 is provided at the top of the fixed cylindrical frame 20. A first movable column 22 is provided around the fifth pivot 21. A first hydraulic rod 23 is provided at the bottom of the first movable column 22. A second movable column 24 is provided at the bottom of the first hydraulic rod 23. A sixth pivot 25 is provided at the connection between the second movable column 24 and the mounting plate 19. The extension and retraction of the first hydraulic rod 23 can move the first movable column 22. The movement of the first movable column 22 can cause the first placement tail plate 1 to rotate through the third pivot 16, thereby realizing the first placement tail plate 1 of the third pivot 16, so as to raise and lower the first placement tail plate 1 from the ground and raise and lower the placed items.

[0020] Example 3 Unlike Embodiment 1, a second hydraulic rod 28 is provided on one side of the second movable column 24, a third movable column 27 is provided at the end of the second hydraulic rod 28, a seventh rotating shaft 26 is provided at the connection between the third movable column 27 and the mounting plate 19, a fourth movable column 29 is provided at the top of the second hydraulic rod 28, and an eighth rotating shaft 30 is provided at the connection between the fourth movable column 29 and the first placement tail plate 1. By extending and retracting the second hydraulic rod 28, the first placement tail plate 1 can be driven to rotate through the eighth rotating shaft 30, so that the first placement tail plate 1 can be adjusted back and forth between a vertical state and a horizontal state. The first placement tail plate 1 in the horizontal state can be used to place items, while the first placement tail plate 1 in the vertical state can be used to fold up, reducing the area occupied on the horizontal ground when the material transport vehicle is parked.

[0021] Working principle: First, by rotating the hand handle 4 with external force, the first bevel gear 5 can be rotated. The rotation of the first bevel gear 5 causes the second bevel gear 6 to rotate, which indirectly drives the threaded column 8 to rotate. The rotation of the threaded column 8 causes the threaded plate 10 to move. The movement of the threaded plate 10 causes the movable plate 12 to move. The movement of the movable plate 12 then drives the push plate 14 to move, which in turn drives the second placement tail plate 15 to move, facilitating the raising and lowering of the second placement tail plate 15 and adjusting the usable area. Then, by extending and retracting the first hydraulic rod 23, the first movable column 22 can be moved, and the first movable column 22... The movement of the moving column 22 can cause the first placement tail plate 1 to rotate through the third rotating shaft 16, thereby enabling the first placement tail plate 1 to be raised and lowered from the ground. The raised and lowered items can be driven to rotate through the eighth rotating shaft 30 by the extension and retraction of the second hydraulic rod 28. This allows the first placement tail plate 1 to be adjusted back and forth between a vertical and a horizontal state. In the horizontal state, the first placement tail plate 1 can be used to place items, while in the vertical state, it can be retracted to reduce the area occupied on the horizontal ground when the material transport vehicle is parked.
