The specific structure is not limited to the above three embodiments, but can also be changed arbitrarily according to needs, for example, no side panels are provided, but rib panels are reserved, etc., as long as the realization of the supporting function can be ensured, the specific structure can be changed arbitrarily. In other embodiments, the support assembly 3 may not be spliced by multiple plates, but in other ways, taking the embodiment shown in Figure 3D as an example, the four support assemblies 3 may all be as shown in Figure 3D Shaped plates, each side of the tank body 1 is connected with a section of reinforcement ring 5 by two plates. It is also possible to adopt solid columns or hollow cylinders, etc. as long as the support effect can be guaranteed.

The working principle of the present invention will be described in detail below with reference to FIG. 7A and FIG. 7B , taking the above-mentioned embodiment as an example.

When the container is in use, a load transfer area needs to be set at the bottom to bear the load caused by gravity or the downward acceleration of the container. Usually, a saddle or a groove as shown in Figure 1 is provided at the bottom of the container. The supporting structure of the tank container of the present invention is arranged at the bottom of the front end of the container and can be used as a load transfer area of the container. As shown in FIG. 7A and FIG. 7B , the supporting structure of the tank container has two supporting surfaces for transferring loads, which are the first supporting surface A1 and the second supporting surface A2 respectively. When the container is assembled with various semi-trailers, the first support surface A1 is in contact with the gooseneck support beam of the semi-trailer, and the second support surface A2 is in contact with the support beam of the chassis of the semi-trailer, which serves as the container support point and bears the load in the vertical direction of the container. . The first supporting surface A1 and the second supporting surface A2 may exist simultaneously, or may exist independently. For example, in the third embodiment, there is only the first supporting surface A1, whereas in the first embodiment, there are two supporting surfaces.

As shown in Figure 6, during transportation, the container needs to bear the impact load caused by the acceleration or deceleration process. Usually, the bottom side beams are set to strengthen the container's ability to withstand impact loads. The support structure of the tank container in this embodiment is arranged at the bottom of the front end of the container, and then connected to the frame 2 through the support beam 4, which can improve the ability of the container to withstand impact loads during transportation. The support beam 4 can be connected to the side plate of the support assembly 3 , and can also be connected to the end seal plate of the support assembly 3 . The purpose is to integrate the frame 2 and the tank body 1 to improve the strength and rigidity of the entire container. Compared with the bottom side sill, it is lighter and simpler to manufacture.

From the above working principle, it can be seen that in this embodiment, two support components relatively fixed on the outer wall of the tank are used to form the groove, which takes up less space than the bending of the whole plate to form the groove. The short distance makes the center of gravity of this part drop, and the structure is simple, no large-scale bending operation is required, the manufacturing process is easy, and the production efficiency is improved. Supporting components can be used both as a load transfer area and as a reinforcement, making them versatile and adaptable.

While this invention has been described with reference to several exemplary embodiments, it is understood that the terms which have been used are words of description and illustration, rather than of limitation. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope of the appended claims. , all changes and modifications falling within the scope of the claims or their equivalents shall be covered by the appended claims.
