[0024] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are merely intended to illustrate and explain the present application, and do not constitute a limitation on the present application.

[0025] The terms "left", "right", and the like, or the positional relationships described in the embodiments, are based on the positional relationships in the drawings of the present application, and are only used for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element must have a specific orientation, a specific orientation structure, and an operation, and therefore cannot be understood as a limitation on the content of the protection of the present application. Figure 2

[0026] As shown in Figure 1 , 2 , the present embodiment comprises a screw rod 1, a driving assembly 2, and a limiting assembly 3; the screw rod 1 is detachably connected with a rotor 4, the driving assembly 2 is used to rotate the screw rod 1, and the limiting assembly 3 is used to realize that the screw rod 1 can move along the axial direction of the rotor 4 while rotating, thereby driving the rotor 4 to move axially and pulling out the rotor 4.

[0027] Specifically, as shown in Figure 2 , the screw rod 1 is arranged axially along the axial direction of the rotor 4, and the left end of the screw rod 1 is threadedly connected with the rotor 4. Of course, any other detachable connection mode in the prior art can also be selected, such as pin shaft connection.

[0028] As shown in Figure 1 , the driving assembly 2 is threadedly sleeved on the screw rod 1, and the driving assembly 2 comprises a driving nut 21 and a rotating block 22 which are fixedly connected, and the driving nut 21 and the rotating block 22 are both provided with internal threads and are threadedly sleeved on the screw rod 1. In order to facilitate hand rotation, the driving assembly 2 further comprises a rotating handle 23 which is fixedly arranged on the driving nut 21.

[0029] The limiting assembly 3 comprises a supporting frame 31, a locking member 32, and a limiting member.

[0030] As shown in Figure 2 , the supporting frame 31 is fixedly arranged outside the housing 5 of the rotor 4, and in the present embodiment, the housing 5 refers to a bearing box. It should be noted that the structure represented by the housing 5 is different in different application scenarios. Figure 1 ​As shown, the support frame 31 is provided with a through hole 311, the diameter of the through hole 311 is greater than the diameter of the screw rod 1, so that the screw rod 1 can rotate relative to the support frame 31, the support frame 31 is provided with a connecting groove 312, the left end of the rotating block 22 extends into the connecting groove 312. In order to perfect the embodiment, the left end of the rotating block 22 and the support frame 31 are provided with a copper gasket 6, which plays a wear-resistant role and increases the service life of the embodiment.

[0031] The driving assembly 2 is rotatably arranged in the support frame 31, and the limiting piece is fixedly arranged at the right end of the support frame 31 and used for limiting the driving assembly 2 from moving axially along the rotor 4. In other words, the rotating block 22 in the driving assembly 2 is rotatably arranged in the support frame 31, and the limiting piece in the embodiment is a pressing plate 33 fixedly arranged at the right side of the support frame 31. The pressing plate 33 is made of copper and is fixed to the support frame 31 by means of an internal hexagonal screw. The pressing plate 33 limits the rotating block 22 from moving axially along the rotor 4. The pressing plate 33 is provided with a through hole 332, and the diameter of the through hole 332 is greater than the diameter of the rotating block 22, so that the rotating block 22 can rotate relative to the pressing plate 33. The end of the pressing plate 33 facing the support frame 31 is provided with a groove 331, and the rotating block 22 is fixedly provided with a stop wing plate 24. In the embodiment, the stop wing plate 24 is integrally arranged with the rotating block 22. The stop wing plate 24 extends into the groove 331, and when the stop wing plate 24 moves to the right, it will abut against the inner wall of the pressing plate 33. Therefore, the pressing plate 33 can limit the stop wing plate 24 from moving to the right.

[0032] As shown in Figure 1 , 2 , the locking piece 32 in the embodiment is a locking nut, which is fixedly arranged inside the housing 5. The central axis of the locking nut is on the same straight line as the central axis of the through hole 311, and the left end of the screw rod 1 is threadedly connected to the locking nut after passing through the through hole 311. Of course, the locking piece 32 can also adopt any other structure in the prior art as long as it is provided with an internal thread and can be threadedly connected with the screw rod 1.

[0033] When the embodiment is used, as shown in Figure 2 , the rotating handle 23 is rotated to drive the nut 21 and the rotating block 22 to rotate together with the screw rod 1. However, the locking nut is fixed and cannot rotate with the screw rod 1. Under the cooperation of the threads, the screw rod 1 can only move to the left and right. When the screw rod 1 moves to the right, the pressing plate 33 abuts against the stop wing plate 24, so that the driving assembly 2 cannot move to the right together with the screw rod 1. The right movement of the screw rod 1 drives the rotor 4 to move to the right together, so as to pull out the rotor 4. The embodiment only needs to operate the driving assembly 2 at the right side of the rotor 4 to realize the axial movement of the rotor 4 and the measurement work, without the need to repeatedly disassemble tools and adjust the working position. The operation is simple and the working efficiency is high. In addition, the components in the embodiment are easy to obtain on the construction site, and the cost is low and the practicality is high.

[0034] It should be noted that the limiting member in the embodiment can also use the existing bearing, the rotating block 22 is fixedly sleeved on the inner ring of the bearing, the outer ring of the bearing is fixedly connected with the support frame 31, when the rotating handle 23 is rotated, the rotating block 22 is rotated to drive the screw rod 1 to rotate, the locking nut is fixed, so that the screw rod 1 drives the rotor 4 to move rightward together, but the rotating block 22 cannot move linearly with the screw rod 1 due to the constraint of the bearing. Of course, the driving assembly 2 can also be replaced by any other structure in the prior art as long as it can drive the screw rod 1 to rotate.

[0035] It should be noted that the above only for the preferred embodiments of the present application, and not for limiting the present application, although the above embodiments of the present application are described in detail, for those skilled in the art, it still can be modified to the technical solutions recorded in the above embodiments, or equivalent replacement of some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
