Skirt and frame of tank container

Abstract

The invention relates to a skirt and frame of a tank container. The skirt comprises a box body and two rear sealing plates. The box body comprises a top straight-barrel arc section, a bottom straight-barrel arc section, a first connection section and a second connection section. One end of the top straight-barrel arc section is connected with one end of the bottom straight-barrel arc section through the first connection section. The other end of the top straight-barrel arc section is connected with the other end of the bottom straight-barrel arc section through the second connection section. The outer diameter of the top straight-barrel arc section and the outer diameter of the bottom straight-barrel arc section are both the same as the outer diameter of a tank body. The upper arc section and the lower arc section are both connected with the tank body through butt joint welding seams. By means of the design of the structure of the skirt, the longitudinal impact force borne by the tank container can be uniformly dispersed and transmitted through multiple routes, each transmission route is simple and direct, the whole frame is reasonable in force bearing, no large stress concentration can be generated, and the railway transportation working conditions can be completely met.

Description

technical field [0001] The invention relates to a frame of a tank container, in particular to a frame for a tank container used for shipping liquefied natural gas (LNG). The frame enables the tank container to transport the LNG through railways, roads and waterways. Background technique [0002] In recent years, LNG tank containers have developed rapidly, especially LNG tank containers suitable for railway transportation. In order to enable the tank container to withstand the large longitudinal impact load of the railway, the existing railway LNG tank container frame is either complex in structure, high in local stress, and self-heavy; Reasonable layout of the row system. [0003] Figure 1 to Figure 5 It is an existing railway LNG tank container frame structure, which is mainly composed of a tank body 1a, a skirt 2a, a longitudinal beam component 3a, an end frame 4a, and a longitudinal beam backing plate 5a. One end of the skirt 2a is welded to the tank body 1a through th...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the technical problem that the existing LNG railway tank container frame structure cannot simultaneously bear large longitudinal impact force and rationally arrange the drainage system, the technical problem to be solved by the present invention is to provide a LNG tank container skirt and frame that can reasonably arrange the pipelines, valves, supports, etc. in the filling system
