Suspension device for superconducting magnet

The invention discloses a suspension device for a superconducting magnet. The suspension device comprises a room temperature container, a cold mass part, supporting rods and pre-tightening rods. The cold mass part is arranged in the room temperature container, a vacuum layer is arranged between the cold mass part and the room temperature container, at least two room temperature container reinforcing parts are symmetrically arranged on the inner surface of the room temperature container, the ends of the two supporting rods are connected to the lower portions of the room temperature container reinforcing parts, and the other ends of the two supporting rods penetrate the vacuum layer slantly downwards to be connected with the cold mass part, the ends of the two pre-tightening rods are connected to the upper portions of the room temperature container reinforcing parts, and the other ends of the pre-tightening rods penetrate the vacuum layer slantly upwards to be connected with the cold mass part. The suspension device is simple in structure and convenient to assemble, is stressed evenly and is high in reliability and low in cost.
