[0002] A semi-trailer is a trailer with the axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailers are generally three-axle semi-trailers, and there are many types of semi-trailers, such as 11-meter barn semi-trailers, 13-meter barn semi-trailers, and low-bed semi-trailers. It is a heavy-duty transportation vehicle connected to the semi-trailer head through a traction pin. When unloading the semi-trailer cargo box, it is usually necessary to use a jacking structure to tilt the cargo box to complete the unloading of the goods;

[0003] An existing self-unloading jacking structure for a semi-trailer cargo box, for example, has a publication number of CN217835457U, which discloses a self-unloading jacking structure for a skeleton transport semi-trailer cargo box, comprising a main body, the inner wall of the main body is rotatably connected to a plurality of motor-controlled screws, the outer walls of the screws are threadedly connected to a moving block, the inner wall of the moving block is rotatably connected to a hydraulic cylinder, one end of the hydraulic cylinder is rotatably connected to a moving box, the inner wall of the main body is fixedly connected to a plurality of slide rails, the slide rails are used to limit the moving block, the inner wall of the moving box is movably linked to a rotating box, and the outer wall of the rotating box is rotatably connected to the inner wall of the main body. When unloading mud or minerals, the motor is first used to rotate the screw to move the moving block outward, so that the moving box is brought out by the hydraulic cylinder, and then the hydraulic cylinder is used to lift the rotating box, so that one side of the side door is tilted toward the ground. In this way, the height of the goods can be lowered when the side door is opened, thereby reducing the impact on the goods and reducing dust. The existing jacking structures are basically completed independently by hydraulic telescopic jacks. The whole process includes the rotation of the jack and the subsequent telescopic jacking. Therefore, the bearing load of the supporting jack is relatively large, and its stability and smoothness cannot be guaranteed during the jacking process, so that the utilization efficiency and stability of the jacking structure cannot be improved.
