Saddle structure of large-volume low-temperature vacuum storage and transportation container

Abstract

The invention relates to a saddle structure, in particular to a saddle structure of a large-volume low-temperature vacuum storage and transportation container. The invention aims at solving the technical problem that an existing saddle structure of a low-temperature vacuum storage and transportation container cannot meet the loading and transportation requirements of low-temperature media with the temperature being -253 DEG C or below. The saddle structure comprises a first protection pipe, a second protection pipe, a bottom sealing plate, a height adjusting unit and a reinforcing unit, wherein the upper end of the first protection pipe is fixedly connected with a through hole formed in the lower cylinder wall of an outer tank body of the low-temperature vacuum storage and transportation container; the lower end of the first protection pipe is arranged at the upper end of the second protection pipe in a sleeving mode and fixedly connected with the second protection pipe; the lower end of the second protection pipe is fixedly connected with the upper surface of the bottom sealing plate to form a closed cavity structure; the upper end of the height adjusting unit is fixedly connected with the lower surface of the bottom sealing plate; and a bottom plate of the height adjusting unit is fixedly connected with a bottom frame of a low-temperature vacuum storage and transportation container transport vehicle.

Description

technical field [0001] The invention relates to a saddle structure, in particular to a saddle structure for a large-volume cryogenic vacuum storage and transportation container. Background technique [0002] In cargo transportation, the tank body of the low-temperature vacuum storage and transportation container usually includes an inner tank and an outer tank, and both the inner and outer tanks include a cylinder body and heads arranged at both ends of the cylinder body. Cryogenic vacuum storage and transportation containers are generally supported and fixed by saddle structures. The existing saddle structure is only suitable for low-temperature containers with a loading medium temperature of -196°C and above. This saddle structure cannot meet the requirements for use of low-temperature containers with a loading medium temperature of -196°C or below, especially -253°C or below. When it is necessary to transport media with a temperature of -253°C and below, the existing sad...
