Fig. 1 and Fig. 2 are referred to, in the first embodiment, reel 100 includes cylinder 101, locating part 102 and strengthens
Part 103.Reel 100 is used to install coil 104.Coil 104 along reel 100 axial winding and be fixed on reel 100,
Coil 104 can produce the axial electromagnetic force that 100 centre position of reel is directed toward by 100 both ends of reel in the energized state, such as
Shown in arrow in Fig. 1.The axial electromagnetic force that coil 104 produces can extrude the locating part 102 of its suffered electromagnetism force direction side,
Locating part 102 is side plate in this embodiment, what deserves to be explained is, in other embodiments, locating part can also be other tools
There is the structure of limit function.
Referring again to Fig. 1 and Fig. 2, the quantity of locating part 102 is multiple, circumferencial direction of multiple locating parts 102 along cylinder 101
It is arranged on the outer wall of cylinder 101.Referring back to Fig. 1, limiting slot 110, limiting slot 110 are defined between adjacent locating part 102
For installing coil 104.Reinforcer 103 is set in the outer wall of cylinder 101, and reinforcer 103 is set in the side of locating part 102
Wall simultaneously is used to resist the electromagnetic force.
In this embodiment, reinforcer 103 is taper cone barrel.Outside so as to reinforcer 103, locating part 102 and cylinder 101
Cavity structure is formed between wall.It should be noted that also may be used between the outer wall of reinforcer 103, locating part 102 and cylinder 101
To form solid construction.Wherein, in the present embodiment, coil 104 is superconducting magnet coil.
Above-mentioned reel 100, including cylinder 101, locating part 102 and reinforcer 103, reinforcer 103 are set in cylinder
101 outer wall, one end of reinforcer 103 are abutted with resisting the locating part 102 of electromagnetic force.Due to the setting of reinforcer 103 so that
Coil 104, which is produced, to be directed toward the axial electromagnetic force effect in 100 centre position of reel by 100 both ends of reel and extrudes locating part
When 102, reinforcer 103 forms locating part 102 and strengthens support, in addition, tubular reinforcer 103 is set in the side of locating part 102

One end of a reinforcer 203 can be abutted against with the centre position of locating part 202, and other reinforcers 203 distribution can with
The both sides for the reinforcer 203 that the centre position of locating part 202 abuts against.Short transverse of multiple reinforcers 203 in locating part 202
On be equally spaced, can effectively disperse the stress concentration that reinforcer 203 and 202 abutted position of locating part produce, each reinforcer 203 by
Power is more uniform.The structure and connection relation of all parts in reel 200 are equal to the coiling described in first embodiment
Cylinder 100, details are not described herein.
Above-mentioned reel 200, there is provided multiple reinforcers being arranged with one heart, so as to further increase the strong of locating part
Degree, so as to offset active force of the axial electromagnetic force to it.
Fig. 4 is referred to, the reel 300 of 3rd embodiment includes cylinder 301, locating part 302 and trapezoidal cylinder reinforcer
303.The quantity of locating part 302 is multiple, and the circumferencial direction of multiple locating part 302 along cylinders 301 is arranged at the outer wall of cylinder 301
On.Limiting slot is defined between adjacent locating part 302, further, limiting slot 310 includes the first limiting slot 311 and the
Two limiting slots 312, the first limiting slot 311 and the second limiting slot 312 are intervally installed.First limiting slot 311 is used for hookup wire
Circle 304.Trapezoidal cylinder reinforcer 303 is sheathed on 312 in the second limiting slot, and one end of trapezoidal cylinder reinforcer 303 and resistance electricity
The locating part 302 of magnetic force abuts.The other end is abutted with limiting another locating part of the second limiting slot 312.
Further, in one of the embodiments, the coil 304 close to 300 both ends of reel is bigger, away from coiling
The coil 304 at 300 both ends of cylinder is smaller.Further, the number of turn of coil 304 can be from the both ends by reel to reel
It is sequentially reduced on middle direction.So as to limit the distance between two locating parts 302 of the first limiting slot 311 can also from by
The both ends of reel to reducing on the direction of the centre of reel successively.Accordingly, two limits for the first limiting slot of restriction
The radial height of position part 302 can also be from the both ends by reel 300 to subtracting successively on the direction of the centre of reel 300
It is small.
In one embodiment, trapezoidal cylinder reinforcer 303 can be positioned only at close at least one of the both ends of reel 300
312 in second limiting slot.Different according to the size and location of coil 304, suffered electromagnetic force size is also different.Closer to
The coil 304 of the end of cylinder 301 is bigger, and the electromagnetic force of generation is also bigger.Trapezoidal cylinder reinforcer 303 is disposed adjacent to reel
