Motor core pulling maintenance platform

Abstract

The present invention discloses a maintenance platform of a motor loose core. The maintenance platform of the motor loose core comprises a front-end double guide rail and a back-end double guide rail which are in inlaid connection, a forward moving car and a carriage car are arranged at two ends of the front-end double guide rail, and a backward moving car is arranged at the back end of the back-end double guide rail; lift beams are disposed at the forward moving car and the backward moving car through door-shaped frames and are driven by lifting mechanisms, and lockable hook-type hoops and dual-rectangular-shaped frames are respectively arranged at the middle parts of the lift beams for support the load side shaft end of a rotor and a false axis; the carriage car is located between the forward moving car and the backward moving car and is provided with an X-shaped scissor jack through a lower platform and an upper slide, and support rollers are arranged at the top of the X-shaped scissor jack and are configured to support the non-load side shaft end of the rotor. The maintenance platform of a motor loose core is able to realize the fast and convenient motor rotor loose core work, and realize the maintenance of a rotor turning through the support structure of the platform itself, so that the effect of integrating a loose core tool and a turning towing bracket is achieved, therefore the maintenance efficiency is improved and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to core-pulling offline maintenance equipment for various small and medium-sized motors, in particular to a motor core-pulling maintenance platform. Background technique [0002] Motors are widely used in the dragging of various mechanical equipment. Various small and medium-sized motors include AC asynchronous motors, DC motors, etc. During the daily maintenance and offline maintenance of motors, the core-pulling process of the motor rotor must be involved, because only Only when the motor stator and rotor are separated can the rotor winding, cage bars, stator coils, slot wedges, etc. be inspected and repaired. For the core-pulling process of the motor, the conventional method is to put a dummy shaft on the rear end of the motor rotor, use steel wire ropes to respectively cover the front end shaft head and the rear end dummy shaft of the rotor, use the crane to lift the rotor to vacate, and ensure that the rotor surface is in con...

AI Technical Summary

Problems solved by technology

During the whole operation process, the requirements for the control of the crane are very high. The crane needs multiple lifting operations, and each rotor movement must pass through the crane, which greatly occupies the utilization rate of the crane. For different series of rotors, different rotors need to be equipped. Barring trailer; seriously reduces the efficiency of motor inspection and maintenance, and increases the cost of motor inspection and maintenance
