[0002] A semi-trailer is a trailer with axles placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transfer horizontal and vertical forces to the tractor. Generally, a semi-trailer is a three-axle semi-trailer, and its types include eleven-meter barn semi-trailers, thirteen-meter barns, low-bed semi-trailers, etc. It is a heavy transportation vehicle connected to the semi-trailer head through a kingpin.

[0003] During the use of a semi-trailer, due to the large mass value after the carriage is fully loaded, the supporting ability of the wheels is relatively large. Therefore, the diameter of the wheels is relatively large, and the position of the carriage from the ground is relatively high. During the unloading process, in order to ensure the safety of the goods and avoid damage to the goods, multiple people and ladders of different heights are required to cooperate for unloading, which consumes a large amount of labor and increases the transportation cost. For this reason, we propose a multifunctional semi-trailer box body. Content of the Utility Model

Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a multifunctional semi-trailer box body, including a carriage 1, a top block 2 is fixedly supported above the rear side of the carriage 1, a limit strip 11 is movably supported above the top block 2, a vertical groove adapted to the limit strip 11 is opened at the top of the limit post 4, a thread is opened at the top end of the limit post 4 and extends upward to above the top block 2. The setting of the limit post 4 can limit the movement range of the movable block 3 during use, so that the movable block 3 can only move up and down parallel to the top block 2, thereby restricting the movement of the unloading plate 15 and avoiding the irregular movement of the unloading plate 15, which affects the safety of the surrounding transfer environment. At the same time, the setting of the limit strip 11 can cooperate with the thread to limit the movement of the limit post 4. The limit post 4 is movably sleeved inside the top block 2, the movable block 3 is movably sleeved outside the limit post 4, a spring 9 is arranged between the movable block 3 and the top block 2, connecting plates 8 are fixedly installed at the upper and lower ends of the spring 9, the bottom surface of the unloading plate 15 is in contact with the top surface of the support plate 14. When the unloading plate 15 is erected, the front end is located between the two support rods 10. After using for a certain period of time, the elastic life of the spring 9 is reduced. When the spring 9 can no longer be normally retracted, first separate the limit strip 11 and the limit post 4, then rotate the limit post 4 to separate the limit post 4 from the top block 2, and then separate the limit post 4 from the movable block 3. At the same time, make the unloading plate 15 in a state perpendicular to the bottom surface of the carriage 1, limit the position of the unloading plate 15 through the connecting strip 12, then separate the spring 9 and the connecting plate 8 from the clamping block 7 and the top block 2 and the movable block 3 respectively, and then replace the new spring 9. A clamping block 7 is fixedly installed on the outer side of the connecting plate 8, a support shaft 13 is supported between the two movable blocks 3, the unloading plate 15 is movably sleeved outside the support shaft 13, and support plates 14 are fixedly installed on the bottom surfaces of the two movable blocks 3. The setting of the support plates 14 plays a role in restricting the movement range of the unloading plate 15, and can support the unloading plate 15 parallel to the ground, facilitating the transfer of goods.

[0021] The bottom surface of the top block 2 is fixedly installed with a support rod 10. The front of the movable block 3 is fixedly connected with a limit rod 5. The horizontal cross-section of the limit rod 5 is rectangular, and the horizontal cross-section of the limit block 6 is L-shaped. The limit post 4 is located inside the spring 9. The cooperation between the limit rod 5 and the limit block 6 plays a role in limiting, which can limit the movement range of the movable block 3 and avoid excessive stretching of the spring 9, resulting in serious damage. The top of the limit rod 5 supports the limit block 6. Above the unloading plate 15 and above the support rod 10, a connecting strip 12 is movably sleeved. The vertical cross-section of the connecting strip 12 is U-shaped. Gradually place the goods above the unloading plate 15, or stand a transfer person above the unloading plate 15 and use part of the goods for weight pressing, so that the unloading plate 15 drives the two movable blocks 3 and the limit rod 5 to move downward. At the same time, the spring 9 will be in a stretched state. Then, make the unloading plate 15 descend a certain distance. The personnel in the carriage continuously place the goods above the unloading plate 15, and the ground personnel continuously pick up the goods through the unloading plate 15, so that the weight above the unloading plate 15 is in a dynamic balance state to assist in unloading.

[0022] In summary, for this multifunctional semi-trailer box body, when in use and unloading is required, first take out the connecting strip 12, then make the unloading plate 15 rotate around the support shaft 13 so that the bottom surface of the unloading plate 15 fits the top surface of the support plate 14. Then gradually place the goods above the unloading plate 15, or stand a transfer person above the unloading plate 15 and use part of the goods for weight pressing, so that the unloading plate 15 drives the two movable blocks 3 and the limit rod 5 to move downward. At the same time, the spring 9 will be in a stretched state. Then, make the unloading plate 15 descend a certain distance. The personnel in the carriage continuously place the goods above the unloading plate 15, and the ground personnel continuously pick up the goods through the unloading plate 15, so that the weight above the unloading plate 15 is in a dynamic balance state to assist in unloading. After using for a certain period of time, the elastic life of the spring 9 decreases. When the spring 9 can no longer retract normally, first separate the limit strip 11 and the limit post 4, then rotate the limit post 4 so that the limit post 4 is separated from the top block 2, and then the limit post 4 is separated from the movable block 3. At the same time, make the unloading plate 15 in a state perpendicular to the bottom surface of the carriage 1. Limit the position of the unloading plate 15 through the connecting strip 12. Then separate the spring 9, the connecting plate 8, and the clamping block 7 from the top block 2 and the movable block 3 respectively, and then replace the new spring 9.
