Abstract

PURPOSE:To perform attachment and positioning of a winding frame simply, by providing a slit in the winding frame of a superconducting coil. CONSTITUTION:In a second tubular winding frame 5, a slit 52 is provided in an axial direction. The outer surface of a first superconducting coil 2 is covered with the winding frame 5 with the slit 52 being opened. By using a positioning pin 6, a first winding frame 1 and the winding frame 5 are fixed. The slit 52 is returned to the original position. By utilizing the elasticity of the winding frame 5, it is closely attached to the coil 2. A piece of second superconducting wire 4 is wound on the coil. Thus the attachment and the positioning of the winding frame 5 can be performed simply.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a superconducting coil winding used in a superconducting device, particularly a superconducting magnet.

[Conventional technology]

Conventional superconducting devices of this type have been constructed as shown in FIGS. 5 and 6. That is, in FIGS. 5 and 6, 1 is the first winding frame, 2 is the superconducting coil wound around the first winding frame 1, and 3 is the superconducting coil arranged on the outer periphery of the superconducting coil 2 in the axial direction. The second winding frame 4, which is divided into two parts, is a superconducting coil wound around the second winding frame 3.

In this conventional method, when the second winding frame 3 is arranged around the outer periphery of the superconducting coil 2, the winding frame 3 is divided into two parts.
After temporarily fixing it, I was taking measurements.

[Problem that the invention seeks to solve]

When the second winding frame 3 is attached to the outer periphery of the superconducting coil 2 in this way, it is supported by a person or a crane, etc., and is temporarily fixed, and then the dimensions are determined. In addition, it was necessary to measure the dimensions after temporary fixing, and then pay attention to the work so as not to cause the winding frame to shift during final installation and to avoid damaging the superconducting coil.

This invention was made in order to solve the problems of the conventional products, and the positioning can be easily performed and the winding frame is supported by the elasticity of the winding frame itself and the tension at the same time as the coil is wound. The aim is to obtain a superconducting device that can be installed without shifting the winding frame.

[Means for solving problems]

In the superconducting device according to the present invention, a second cylindrical winding frame having a slit in the axial direction is closely arranged on the outer periphery of the first superconducting coil wound around the first cylindrical winding frame. A second superconducting coil is wound around the outer periphery of the second winding frame.

[Effect]

The second winding frame of the superconducting coil according to the present invention utilizes the elasticity of the second winding frame itself when the slit is pushed open and attached to the outer periphery of the first superconducting coil, and the slit is returned to its original state. Since the winding frame is brought into close contact with the first superconducting coil, mounting and positioning of the winding frame can be easily performed and accuracy can be improved.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. That is, in FIGS. 1 to 3, 1 is a first winding frame having a positioning hole 11, 5 is a second winding frame disposed around the outer circumference of the first superconducting coil 2, and has a positioning hole 51 and a slit 52. Winding frame, 6 is the first and second winding frame 1.5
This is a positioning pin inserted into the positioning hole 11.51 of the winding frame 1.5 to fix the winding frames 1.5 to each other.

The rest of the structure is the same as the conventional one shown in FIGS. 5 and 6, so the explanation will be omitted. Although the positioning holes 51 of the second winding frame 5 shown in FIG. 3 are formed in a circular shape and an elliptical shape, they may also be formed in an elliptical shape as shown in FIG. 4.

With this structure, the second winding frame 5 having a slit 52 is placed over the outer periphery of the first superconducting coil 2 by pushing the slit 52 open, and the positioning pin 6 is used to connect the first and second winding frames. 1.5 is attached, and then the slit 52 is returned to its original position and the elasticity of the second winding frame 5 itself is used to bring it into close contact with the superconducting coil 2, and the second superconducting wire 4 is wound thereon.

〔Effect of the invention〕

As described above, in the superconducting device according to the present invention, since the slit is provided in the winding frame of the superconducting coil, the winding frame can be mounted and positioned in a cylindrical manner, and a highly accurate device can be obtained.
