Preferably, the other end of the auxiliary support pipe is welded to the tank body through a first backing plate, and welded to the reinforcement ring through a second backing plate.

Preferably, the thickness of the first backing plate and/or the second backing plate can be adjusted according to the actual design, for example, it can be 4-5 mm, preferably a stainless steel backing plate with a thickness of 4 mm.

Preferably, the connection position between the other end of the auxiliary support tube and the first backing plate is cut into an arc to fit the first backing plate, so as to increase the clear height distance between the auxiliary support tube and the bottom surface of the bottom corner piece.

Preferably, a reinforcement ring is provided on the outer surface of the tank where the reinforcement ring is displaced inward by a distance, and the reinforcement ring is connected to the reinforcement ring through a groove-shaped piece.

Preferably, one end of the channel member is connected to the reinforcement ring, and the other end is connected to the side of the first backing plate relative to the other end of the auxiliary support tube.

Preferably, the reinforcing ring is arranged around the entire outer surface of the tank to form a ring structure, and the reinforcing ring is arranged around a part of the outer surface of the bottom of the tank to form an arc structure.

Preferably, the bottom surface of the auxiliary support tube forms an acute angle with the bottom surface of the bottom corner piece.

The present invention optimizes the design of the end frame structure through stress analysis, especially the connection structure of the auxiliary support pipe, so that the structure is simple, and the clearance space between the bottom corner piece and the bottom surface of the bottom corner piece is large, and the collision between the bottom surface of the "A" frame and the girder of the vehicle is avoided. At the same time, the auxiliary support tube is designed to be strengthened at the circumferential reinforcement ring, and by adding arc-shaped reinforcement rings and grooved parts, the overall strength of the frame structure is higher and the force is better. The frame structure of the exchangeable tank container of the present invention is optimized through FEA calculation, and the impact test result is ideal.

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

Detailed ways

As shown in Figures 3 and 4, the interchangeable body tank container 200 of the present invention includes a tank body 21, a front end frame 22 and a rear end frame 23 arranged at the front and rear ends of the tank body 21, and a plurality of outer frames surrounding the entire tank body 21. Reinforcing rings 24a-24d, and escalators 211 and walkways 212 and the like. The front end frame 22 and the rear end frame 23 include end lower beams 221 , side beams 222 , and upper end beams 223 , and are provided with top corner pieces 224 and bottom corner pieces 225 . In particular, at least one auxiliary support pipe is provided on the front end frame 22 and the rear end frame 23 of the present invention, for example, two auxiliary support pipes 226a and 226b are provided, which start from the bottom corner piece 225 and extend upwards to the reinforcement ring. 24a, 24d, that is, the first reinforcement ring 24a, 24d closest to the bottom corner piece 225, and welded together with the tank body 21 and the reinforcement rings 24a, 24d. This inclined design increases the clear height between the auxiliary support tubes 226a and 226b and the bottom plane of the bottom corner piece 225, thereby avoiding the collision between the bottom surface of the auxiliary support tubes and the frame of the vehicle, causing fatigue damage, and making the end frame structure Safer and more reliable.

Since the front frame 22 and the rear frame 23 are similar in structure, the auxiliary support tube structure of the present invention will be further described in detail below by taking the front frame 22 as an example.

As shown in Figures 5A and 5B, one end of the two auxiliary support pipes 226a and 226b on the front end frame 22 is respectively connected to the bottom corner pieces 225 at both ends of the lower beam 221 at the end, and the other end moves closer to the middle and tilts upward at an angle d Extend, intersect and connect at the reinforcing ring 24a, and form a triangle with the end lower beam 221, that is, form a commonly known "A" frame. The angle d is an acute angle formed by the bottom surfaces of the auxiliary support tubes 226a, 226b and the bottom surface 225a of the bottom corner piece 225 . In addition, the other ends of the auxiliary support pipes 226 a and 226 b are welded to the tank body 21 through the first backing plate 229 , and welded to the reinforcing ring 24 a through the second backing plate 227 . The thickness of the first backing plate 229 and the second backing plate 227 may be 4-5 mm, preferably, they may be stainless steel backing plates with a thickness of 4 mm.

In order to further increase the clear height distance between the auxiliary support pipe 226a and the bottom surface 225a of the bottom corner piece 225, as shown in FIG. The first backing plate 229 is bonded.

In addition, as shown in FIG. 5C , the present invention has carried out a strengthening design at the connection between the auxiliary support pipes 226a, 226b and the reinforcement ring 24a, that is, a shorter one is arranged on the outer surface of the tank where the reinforcement ring 24a is displaced inward by a suitable distance. Reinforcing ring 25, such as an arc-shaped reinforcing arc, is connected between the reinforcing ring 24a and the reinforcing ring 25 by a stainless steel trough 228, one end of which is connected to the reinforcing ring 25, and the other end is opposite to the reinforcing ring 25. The other ends of the auxiliary support tubes 226a, 226b are connected to one side of the first backing plate 227, as shown in FIG. 5D.

As shown in FIG. 5C , the first backing plate 229 has an arc edge 229a, which cooperates with the auxiliary support tubes 226a, 226b forming the triangle.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
