Suspension device for low-temperature superconducting magnet helium tank

Abstract

A suspension device for a low-temperature superconducting magnet helium tank comprises a dewar, a cold shield is arranged in the dewar, and the helium tank is arranged in an inner cavity of the cold shield. A first upper adjustment pull rod component and a second upper adjustment pull rod component are arranged on the upper left and right of the dewar respectively; a first bearing pull rod component and a second bearing pull rod component are arranged on the left and right sides of the upper middle of the dewar; a first lower adjustment pull rod component and a second lower adjustment pull rod component are arranged on the lower left and right of the dewar respectively; pull rods of the first bearing pull rod component and the second bearing pull rod component are mainly used for bearing strength, and a mounting center of the top end and the bottom end of the helium tank is adjusted by the aid of a locking nut. The suspension device for the low-temperature superconducting magnet helium tank has the advantages that owing to the structural form and the distribution form of the suspension device, high operability in strength bearing and centering of the suspended helium tank is achieved, and the suspension device is simple in structure and manufacturing process and easy to mount; excellent stress conditions and low loading, unloading and transport cost are achieved; adjustment of the mounting center is convenient; in addition, the suspension device is structurally convertible, high in universality and easy to design and verify.

Description

technical field [0001] The invention belongs to the technical field of low-temperature superconductivity, and in particular relates to a suspension device for a helium tank of a low-temperature superconducting magnet. Background technique [0002] For the zero-volatility low-temperature superconducting magnet system, the basic structure is that the superconducting coil is immersed in a cavity filled with liquid helium, which is called a helium tank. In order to keep the helium tank at a certain low temperature so as not to vaporize the liquid helium, it is necessary to minimize the transfer of external heat to the helium tank. One of the ways is to hang the helium tank through tie rods, which can greatly reduce the conduction heat from the outside to the helium tank. [0003] But because the whole helium tank is suspended by the tie rods, in addition to the gravity of the helium tank itself, the tie rods also have to bear the impact caused by the unloading and bumping durin...

Problems solved by technology

[0004] There are many types of existing tie rod structures, but many of them are used for specific structures or occasions, and have specificity. In addition, they have the disadvantages of relatively complicated structure and difficult adjustment of the center.
