Description

Technical Field

[0001] The invention relates to a wear repair device for a slip ring of a synchronous motor in a moving state, belonging to the technical field of mechanical repair. Background Art

[0002] Synchronous motors are widely used in the industrial field as electrical equipment. In daily life, synchronous motors are usually in continuous operation. This long-term, high-load operation easily causes wear of the internal parts of the motor. In particular, key parts such as bearings, rotors, stators, and slip rings will gradually wear out due to friction, heat, vibration and other factors after long-term operation, affecting the operating efficiency of the motor and may even cause the motor to shut down or fail.

[0003] At present, the traditional motor maintenance method is usually to disassemble, inspect, repair and replace parts after the equipment is shut down. For example, when repairing the slip ring, first shut down and ensure that the power is disconnected. After the motor is powered off, the maintenance personnel need to disassemble it to repair the slip ring. The disassembly step is time-consuming and complicated. Especially in large motors, the disassembly of the slip ring requires the use of a sling or other professional tools to ensure accuracy and safety. Secondly, the slip ring is inspected. The surface of the slip ring should be smooth. If there is obvious wear, ablation, scratches or depressions on the surface, it means that the contact performance of the slip ring has decreased. It needs to be repaired by grinding or polishing after disassembly. Then the repaired slip ring is reassembled and debugged. After confirmation, the motor is put back into production. This method not only requires a long downtime, but also has a great impact on the continuity of the production process and industrial production efficiency. Especially in some critical occasions, downtime not only leads to production interruption, but also may bring huge economic losses.

[0004] Therefore, it is necessary to design a new type of wear repair device for synchronous motor slip rings in motion, which can repair damaged parts in real time while the motor is running continuously, significantly reducing downtime and improving the operating efficiency of the equipment. At the same time, it has the function of multi-axis movement and adjustment, which can flexibly adapt to the repair needs of different parts of the synchronous motor slip ring, thereby meeting the requirements for flexibility and efficiency in the motor maintenance process.

Moreover, the horizontal and vertical adjustment design of the moving part 1 is convenient and flexible to adjust the position of the repair part 4, and is suitable for motors of different models and specifications, so that it has strong versatility and meets the needs of various application scenarios.

[0022] The repairing part 4 includes a motor 44, a polishing wheel 45 and a vertical plate 41, and the vertical plate 41 is installed on the second nut 35; the upper and lower ends of the vertical plate 41 extend into an upper arm plate 43 and a lower arm plate 42 to fix the motor 44, and the upper arm plate 43 is provided with a through hole, and the rotating shaft of the motor 44 passes through the through hole and is connected to the polishing wheel 45, which is used to repair the slip ring in motion, and can ensure that the repair effect reaches the expected standard, extend the service life of the motor, and reduce the failure rate.

[0023] An insulating pad 46 is provided on the back of the vertical plate 41 of the repair part 4.
