Description

Technical Field

[0001] This utility model relates to the field of superconducting magnet component transportation technology, specifically to a heavy-duty precision workpiece logistics box. Background Technology

[0002] A superconducting magnet is an electromagnet made by using a type II superconductor with a high transition temperature and a particularly high critical magnetic field to form coils at low temperatures. Superconducting magnets are divided into two types: traditional cylindrical superconducting magnets and open-type superconducting magnets. Cylindrical superconducting magnets mainly consist of a core, two coils outside the core, and a frame connecting the core and coils. In modern factories, the production of large equipment is completed through the cooperation of numerous factories. Various components are transported from different component factories to the final assembly plant, where they are finally assembled into the finished product. Among the components of a superconducting magnet, the core is ring-shaped and weighs at least one ton. Circuit boards and other devices are arranged on the inner and outer circumferences of the core. Furthermore, to maintain its superconducting properties, it needs to be stored in an environment of 17-27°C. Therefore, how to transport the core during the production process of superconducting magnets is a challenge. Utility Model Content
