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 superconducting, and particularly 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 ensure that the helium tank maintains a certain low temperature and does not allow liquid helium to vaporize, it is necessary to minimize the transfer of external heat to the helium tank. One way is to suspend the helium tank through a tie rod, which can greatly reduce the heat conduction from the outside to the helium tank. [0003] However, because the entire helium tank is suspended by the pull rod, the pull rod must bear the impact force caused by the bumps during transportation and unloading in addition to the gravity of ...
