Description

Technical Field

[0001] The utility model relates to the technical field of superconducting coils, in particular to a mounting bracket for a superconductor. Background Art

[0002] Superconducting technology is of paramount importance in modern science and engineering. Superconducting coils, key components in superconducting technology, are widely used in numerous high-tech fields, including magnetic resonance imaging (MRI) equipment, particle accelerators, and magnetic levitation trains. Superconducting coils enable zero-resistance current transmission at extremely low temperatures and generate strong and stable magnetic fields, which are crucial for the high-performance operation of these devices.

[0003] The superconducting coil mounting bracket is a structural component used to support and secure the superconducting coil. It not only needs to provide stable physical support for the superconducting coil to ensure its shape accuracy and positional stability during operation, but also meet special requirements such as structural reliability and thermal conductivity in low-temperature environments. Existing superconducting coil mounting brackets typically utilize a one-piece design. This one-piece structure designates the entire mounting bracket as a single, integral component, manufactured through casting, forging, or one-shot molding.

[0004] However, during the use of the superconducting coil mounting bracket, local damage may occur. For example, due to long-term exposure to magnetic field forces or thermal stress in a low-temperature environment, a local area of ​​the bracket may experience material fatigue, cracking and other problems. However, the integrated structure makes it impossible to repair or replace the locally damaged part separately in this case. Moreover, since the bracket is an integral unit, once a local problem occurs, the entire mounting bracket often needs to be replaced. This not only increases the maintenance cost, but also complicates the replacement process, requiring readjustment of the installation position and parameters of the superconducting coil, which increases the downtime of the equipment.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 A superconductor mounting bracket, hereinafter referred to as "the device," comprises a central tube 1 and end plates 2 mounted at both ends of the central tube 1. The central tube 1 is a hollow cylindrical structure, enclosed by two first curved pieces 11 and two second curved pieces 12. Both sides of the first curved piece 11 and the second curved piece 12 are provided with an embedding groove 14 and an embedding protrusion 15 adapted to the embedding groove 14. The first curved piece 11 and the second curved piece 12 are connected.

[0024] Specifically, the central tube 1 is composed of a first arc-shaped piece 11 and a second arc-shaped piece 12 spliced ​​together, and the end plate 2 and the central tube 1 can be detachably connected, so that the superconducting coil mounting bracket adopts a non-integrated structure. When local damage occurs, the damaged local area can be repaired or replaced separately without replacing the entire mounting bracket, thereby reducing maintenance costs. Compared with the existing integrated structure, it avoids overall replacement due to local problems, saves material and labor costs, and the non-integrated structure allows different materials to be selected according to the needs of different parts, so that the mounting bracket can better exert the advantages of each part of the material when facing complex environments such as magnetic field force and low-temperature thermal stress, thereby improving the overall reliability and durability of the mounting bracket.

[0025] See Figure 3-Figure 5The embedded groove 14 is recessed inward from the sidewall surfaces of the first arc-shaped piece 11 and the second arc-shaped piece 12 , and the diameter of the embedded groove 14 is at least smaller than the maximum distance between the groove walls of the embedded groove 14 .

[0027] Specifically, the embedding groove 14 is an arc-shaped groove. When the extension block 17 is inserted into the embedding groove 14, it is easier to extend into the embedding groove 14 due to the change in the groove diameter of the groove wall, and has a certain guiding effect; at the same time, the arc-shaped groove wall is smoother, reducing the sliding friction generated when the embedding protrusion 15 is engaged.

[0031] Specifically, the end plate 2 and the center tube 1 can be conveniently combined and connected through the provided screw holes 13 .

[0032] See Figure 1 The outer wall and the inner wall of the central tube 1 are both smooth structures, and the outer wall and the inner wall of the central tube 1 are both coated with Teflon coating.
