[0002] The tank container (often referred to as "tank box" for short) is mainly composed of a tank body and a frame supporting the tank body, and the frame bears the load of the tank body and transmits the load to the transportation tool (such as a transport vehicle, a transport ship, etc.). In the prior art, for tank containers with a larger volume, the volume range is 27m 3 ~ 37m 3 , and the maximum design total weight is 36T ~ 39T, the frame usually includes an end frame supporting both ends of the tank body and a saddle supporting the bottom of the tank body, wherein the wrap angle of the saddle to the tank body is generally in the range of 80° ~ 100°, and the load borne by the saddle is smaller. According to the current development trend of tank containers, developing tank containers with larger volume is the general trend, and the current saddle structure cannot meet the requirements.

[0003] In some better structures, the end frame and the saddle are also connected by a connecting beam to increase the carrying capacity. However, in the existing structure, the two ends of the connecting beam are connected to the bottom of the end frame and the bottom of the saddle respectively, and the load transmission effect is not good, and the increase of the overall carrying capacity of the frame is limited. In order to meet the demand of larger volume tank container, the frame structure of the tank container still needs to be further optimized. SUMMARY

[0004] The purpose of the present application is to provide a tank container which can have a large volume and a large load.

[0005] To solve the above technical problems, the present application adopts the following technical scheme: a tank container, comprising a tank body and a frame supporting the tank body; the frame comprises two end frames supporting both ends of the tank body, a plurality of saddles arranged along the longitudinal direction of the tank body and supporting the bottom of the tank body, and a bottom support assembly connecting the end frame and the adjacent saddle; the saddle has a concave supporting surface, and the supporting surface is adapted to the circumferential contour shape of the bottom of the tank body to support the tank body; in the cross section of the tank body, the included angle between the end points of the supporting surface and the center line of the tank body is not less than 150°; the bottom support assembly comprises a connecting beam and a support; one end of the connecting beam is connected to the bottom corner of the end frame, and the other end is connected to the saddle, and the connecting part has a height interval with the bottom of the saddle; the support is connected to one end of the connecting beam close to the saddle, and an integral support plate extending along the longitudinal direction of the tank body is formed on the support; and the support plate is fixedly connected to the tank body.

[0006] Preferably, the saddle comprises at least two supporting plates longitudinally spaced apart along the tank body, a bottom plate connecting the bottom of each supporting plate, a sealing plate connecting the side of each supporting plate, and a reinforcing plate connecting two adjacent supporting plates; the upper edge of each supporting plate forms the supporting surface; the connecting beam and the support are both connected to the supporting plate, and the connecting beam and the bottom plate are spaced apart in height.

[0007] Preferably, the end of the support plate is connected to the saddle; the saddle further comprises a reinforcing pipe which is an integrally formed structure with a closed cross-sectional shape, and the two ends of the reinforcing pipe are connected to the supporting plate; the reinforcing pipe is longitudinally arranged along the tank body and is opposite to the position of the support plate.

[0008] Preferably, the reinforcing pipe is a round pipe or a square pipe.

[0009] Preferably, the tank body comprises a tank body proper and a reinforcing ring circumferentially arranged outside the tank body proper; the saddle is welded and fixed to the reinforcing ring.

[0010] Preferably, the support plate is in the same plane as the central axis of the tank body.

[0011] Preferably, the support is integrally formed by bending, and further comprises a transition plate bent and connected to the support plate and a connecting plate bent and connected to the transition plate; the connecting plate is connected to the connecting beam, and the axis of the connecting plate is parallel to the axis of the connecting beam.

[0015] From the above technical solutions, the present application has at least the following advantages and positive effects: In the present application, the frame bottom is supported by a saddle and a bottom support assembly, wherein the saddle has a large included angle structure, which effectively improves the load-bearing strength of the saddle and improves the load distribution condition; the saddle and the end frame are connected by a connecting beam to improve the load-bearing capacity. In particular, the connecting point of the connecting beam and the saddle is spaced apart from the bottom of the saddle by a height, and the connecting beam is downwardly inclined in the direction from the saddle to the end frame, which is more conducive to the transmission of the saddle load to the end frame. The support member is connected to the tank body by the integrally formed longitudinally extending support plate, which can directly bear a part of the tank load and transmit it to the end frame, increasing the load transmission path and being more conducive to improving the overall load-bearing capacity and load transmission capacity of the frame. In the tank container of the present application, the frame structure and the connection mode thereof and the tank body can bear greater tank load, so that the tank container can have greater volume and design load.

[0026] Referring to Figure 3 and Figure 4 , the saddle 22 mainly comprises two supporting plates 221 spaced apart along the longitudinal direction of the tank body 1, a bottom plate 222 connecting the bottom of the two supporting plates 221, an enclosing plate 223 connecting the side of the two supporting plates 221, and a reinforcing plate 224 and a reinforcing pipe 225 connected between the two supporting plates 221.

[0027] The supporting plate 221, the bottom plate 222 and the enclosing plate 223 are surrounded to form an internally hollow structure with an open upper end. The reinforcing plate 224 has a plurality of reinforcing plates 224 spaced apart in the hollow structure to reinforce the structure of the saddle 22. The reinforcing pipe 225 is two in number and symmetrically arranged in the hollow structure; the reinforcing pipe 225 is an integrally formed structure with a closed cross section, which can be a circular pipe, a square pipe or other polygonal cross section pipe, and the reinforcing pipe 225 is vertically connected to the two supporting plates 221, with its axis consistent with the longitudinal direction of the tank body 1.

[0028] The upper edge of the supporting plate 221 is generally concave arc-shaped, which is adapted to the circumferential contour shape of the bottom of the tank body 1, and the upper edges of the two supporting plates 221 are flush to form a supporting surface 220 for supporting the tank body 1. Preferably, the upper edge of the supporting plate 221 is welded and fixed to the reinforcing ring 12 of the tank body 1.
