Specifically, the standing unit 300 includes a rotation unit 310, a seating unit 315, and a rotation control unit 305. At this time, the rotation part 310 is curved at its outer periphery, and the seating part 315 is provided inside the rotation part 315 as a component to which the coil assembly 10 is seated, (320) is provided to support the outer periphery of the rotation part (310) at a lower part of the rotation part (310).

A plurality of driving rollers 320 may be provided between the rotation regulating unit 320 and the rotation unit 310 so that the rotation unit 310 rotates the driving unit 320 as shown in FIG. And driven to rotate in the circumferential direction as the roller 320 rotates.

The rotation angle of the rotation part 310 changes with a relative angle of the seating part 315 with respect to the ground, and the coil assembly 10 can be raised in this process.

14 is a front view of the standing unit 300. As shown in FIG. 14, the seating portion 315 is formed so that its height decreases from both sides toward the center. Accordingly, a spacing space S may be formed between the central portion of the seating portion 315 and the coil assembly 10.

This is because a part of equipment such as a forklift or the like for transporting the coil assembly 10 seats the coil assembly 10 on the seating part 315 and is released by utilizing the spacing space S .

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
