Detailed implementation manners

[0023] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the illustrated embodiments are not intended to limit the present utility model.

[0024] Referring to Figure 1-4 As shown, the present utility model discloses a dynamic adjustable winding and unwinding device for second-generation high-temperature superconducting tapes, including a winding shaft 1, a threaded cover plate 2, a fixed shaft 3, a sliding cover plate 4 and an adjusting handle 5; the threaded cover plate 2 is fixedly arranged at one end of the winding shaft 1, the adjusting handle 5 is connected to the threaded cover plate 2, the sliding cover plate 4 is fixedly arranged at one end of the fixed shaft 3, and one end of the fixed shaft 3 with the sliding cover plate 4 is key-connected to the winding shaft 1, so that the fixed shaft 3 can rotate synchronously with the winding shaft 1 and can slide in the inner cavity of the winding shaft 1.

[0025] Furthermore, it further includes a reel clamp 6, and the reel clamp 6 is arranged outside the winding shaft 1 for locking the winding reel on the winding shaft 1.

[0026] As Figure 5 shown, in this embodiment, the reel clamp 6 is provided with a first locking ear plate 61 and a second locking ear plate 62, and a locking bolt 63 is arranged between the first locking ear plate 61 and the second locking ear plate 62. The design of the locking bolt 63 facilitates the locking of the reel clamp 6 on the winding shaft 1 or the removal from the winding shaft 1.

[0027] Further, a retaining piece 11 is provided at one end of the winding shaft 1 away from the threaded cover plate 2, and the retaining piece 11 and the reel clamp 6 clamp the winding reel 100 therebetween. The retaining piece 11 is annular and integrally formed with the winding shaft 1. In this embodiment, the diameter of the retaining piece 11 is smaller than that of the winding reel 100.

[0028] In this embodiment, the periphery of the threaded cover plate 2 is connected to the winding shaft 1 through a locking member.

[0029] Preferably, the adjusting handle 5 includes a handwheel 51 and a screw rod 52. The handwheel 51 is connected to one end of the screw rod 52, and the other end of the screw rod 52 is connected to the threaded cover plate 2.

[0030] Further, a threaded hole adapted to the screw rod 52 is provided at the central position of the threaded cover plate 2. When the screw rod 52 rotates in the threaded hole, the threaded cover plate 2 can be adjusted in position along the direction of the screw rod 52. When the handwheel 51 rotates, the screw rod 52 rotates in the threaded hole of the threaded cover plate 2, and the rotational motion of the screw rod 52 is converted into a linear movement of the threaded cover plate 2 along the direction of the screw rod 52. When the threaded cover plate 2 moves, it drives the winding shaft 1 to shift, so that the winding reel 100 follows the winding shaft 1 to shift together, and the winding reel 100 is adjusted to a suitable position.

[0031] In this embodiment, the screw rod 52 of the adjusting handle 5 extends into the interior of the winding shaft 1 and is connected to the sliding cover plate 4 provided on the fixed shaft 3 through a bearing. When the adjusting handle 5 rotates, it can ensure smooth rotation between the adjusting handle 5 and the sliding cover plate 4, and keep the front and rear positions of the adjusting handle 5 and the sliding cover plate 4 unchanged.

[0032] In addition, a spline 31 is provided on the outer wall of the fixed shaft 3, and a key groove 12 adapted to the spline 31 is provided in the inner cavity of the winding shaft 1. The fixed shaft 3 penetrates into the inner cavity of the winding shaft 1, and the spline 31 of the fixed shaft 3 and the key groove 12 in the winding shaft 1 are connected in a matching manner, enabling both the winding shaft 1 and the fixed shaft 3 to rotate synchronously and allowing the fixed shaft 3 to slide back and forth in the inner cavity of the winding shaft 1.

[0033] In this embodiment, a locking and fixing hole 32 is provided on the outer wall of the fixed shaft 3, and the fixed shaft 3 and the transmission shaft of the equipment are locked and fixed by screws passing through the locking and fixing hole 32.

[0034] When the equipment is running normally, the entire adjustable coiling device rotates with the equipment drive shaft. When it is necessary to adjust the front and rear positions of the coiling disc 100, rotate the adjusting handle 5 clockwise. The threaded cover plate 2 is fixed to the coiling shaft 1. When the coiling shaft 1 rotates, the coiling disc 100 moves forward together with the coiling shaft 1. Rotate counterclockwise, and the coiling disc 100 moves backward until it is adjusted to the appropriate position, effectively avoiding damage caused by scraping the edge of the superconducting tape during coiling, and also avoiding downtime caused by the need to adjust the front and rear positions of the coiling disc 100, improving work efficiency, and can be adjusted at any time during normal processes.

[0035] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
