Because the rotating speed of the driving wheel 9 when the lowest stability is kept is faster than that of the slip ring assembly, and the diameter of the driven wheel 4 is larger than that of the driving wheel 9, the rotating speed of the driving wheel 9 can be higher than that of the driven wheel 4, and the rotating speed of the slip ring assembly is adapted to the rotating speed of the slip ring assembly during maintenance of the slip ring assembly.

Alternatively, the motor 8 is fixedly connected with the fixing frame 7 through a connecting screw.

It should be noted that, the specific process of maintaining the slip ring by the combined slip ring maintenance device is divided into the following steps:

1. installing a slip ring: the slip ring assembly is mounted on the driven wheel 4 by means of a slip ring mount 5, in particular by using three bolts, when the nacelle part of the slip ring assembly is inside the casing 3 and its wires are fixed on the casing 3 by means of a wire mount 6.

2. And (3) checking the slip ring: the housing of the slip ring assembly was disassembled and the inside of the slip ring assembly was checked for the status of the slides and the brush filaments.

3. The starting device comprises: and starting the motor 8 of the maintenance device, adjusting the frequency converter from low to high, and further adjusting the rotating speed of a rotating shaft of the motor 8 to be proper.

4. Cleaning and maintaining a slide way: when the slip ring component is maintained through the maintenance device, the slide way part of the slip ring component is driven to rotate by the maintenance device, whether the slide way is intact or not is firstly checked at a proper position where the slide way is exposed, and then the slide way is cleaned by using cotton swabs and the like. The cleaning of the slide way can be finished only by lightly contacting the cotton swab with the slide way and depending on the rotation of the slide way. It should be noted that, due to the slip ring bearing rotatably connected between the brush wire part of the slip ring assembly and the slideway part, the brush wire part of the slip ring assembly can be kept relatively static with the ground under the action of self gravity, and the slideway part of the slip ring assembly rotates with respect to the ground. After the slideways of the slip ring assembly are cleaned one by one, the motor 8 is stopped, lubricating liquid is dripped into each slideway, and the motor 8 is started again to rotate the slideways, so that the lubricating liquid is uniformly smeared on the slideways.

It is worth mentioning that when the slip ring is maintained, the nacelle part which is the slip ring assembly and is positioned in the sleeve 3 has long wires, and the long wires are required to be fixed on the sleeve 3 and rotate along with the sleeve 3, so that the wires of the nacelle part and the driven wheel 4 are kept relatively static, and the damage of the wires inside the slip ring assembly nacelle caused by the stress condition at the wire connection position is reduced.

It can be understood that, when maintaining the sliding ring, stretch out sleeve 3 one side and follow the slide part for the slip ring subassembly of perforation corresponding position of driving wheel 4, the slide part of this slip ring subassembly rotates along with from driving wheel 4, can drive action wheel 9 through motor 8 and drive and rotate, compare in artifical rotatory slip ring subassembly rotating spindle conducting ring, the slide part promptly, the rotational speed of motor 8 driven is faster, the converter of connecting through motor 8 simultaneously can adjust the rotational speed of slide part, required time when can reducing the sliding ring clearance.

Particularly, the slip ring assembly is not fixed during pure manual maintenance, which may cause a series of problems, such as when the main shaft conductive ring, i.e. the slide way portion, is cleaned, the slide way assembly may move due to the appearance problem when being stressed, which may cause difficulty in cleaning impurities at the edge of the main shaft conductive ring. And through fixing the slip ring subassembly relatively on support 1, can be when clearing up main shaft conducting ring edge for the slip ring subassembly atress obtains support of support 1, and is static relatively on the ground, thereby makes the artifical degree of difficulty that carries out the slide clearance reduce, thereby can improve the maintenance quality when maintaining the sliding ring.

In addition, because the brush silk part of slip ring subassembly is static relatively ground, can reduce the damage problem that the mistake bumped the brush silk and leads to, and after the slip ring subassembly was fixed, can reduce the maintenance tool mistake that the sliding ring rocked and lead to and bump the brush silk and then damage the condition of brush silk.

Meanwhile, the slip ring is manually rotated relatively, the motor 8 can control the relative rotation state of the slide way and the brush wire stably, the rotation speed and time of the slip ring are controllable, the number of rotation turns in manual rotation can be reduced, the condition that lubricating liquid is smeared uniformly and cannot arrive at the place can be reduced, and the maintenance quality of the slip ring can be improved.

It should be noted that the above-mentioned disclosure and the detailed description are intended to demonstrate the practical application of the technical solutions provided in the present application, and should not be construed as limiting the scope of the present application. Various modifications, equivalent substitutions, or improvements within the spirit and scope of the application may occur to those skilled in the art. The protection scope of this application is subject to the appended claims.
