Mining large electromotor coupler dismounting device

Abstract

The invention discloses a mining large electromotor coupler dismounting device, relating to an underground maintenance equipment of coal mines. The device comprises a bracket, a hydraulic cylinder 4 and snap-gauges 6, wherein the bracket comprises an installing plate1 and stud bolts; the installing plate1 is provided with four circle holes; four stud bolts 3 are arranged; one end of each stud bolt is inserted into the round hole of the installing plate 1 and is fixed by a regulation nut 2; two snap-gauges 6 are provided; the inner sides of the snap-gauges 6 are provided with arc-shaped grooves 6-1; the other ends of the stud bolts are inserted in the snap-gauges 6 and are fixed by the regulation nut 2; and the body of the hydraulic cylinder 4 is vertically fixed on the inner side of the installing plate1. When the mining large electromotor coupler dismounting device is used, a piston 4-1 passes through the middle drainage hole of a coupler 5; the end part of the piston 4-1 contacts with the end part of a motor shaft 7-1; the hydraulic cylinder 4 is started, the snap-gauges 6 eject out the coupler 5 to cause the coupler 5 to be separated from the motor shaft 7-1; and the large electromotor coupler can be disassembled and is convenient and quick, and time and labor are saved.

Description

technical field [0001] The invention relates to mining equipment, in particular to a shaft coupling dismounting device for a large motor used in underground coal mines. Background technique [0002] The underground environment of coal mines is harsh, and there is a lot of water in most places. The motors used in large equipment such as coal shearers, scrapers, belt conveyors, and winches are often damaged due to improper use and maintenance. Most of the motors cannot be used normally because of damp, resulting in reduced insulation. The motor coupling must be removed and the motor repaired. It is also possible to repair some small faults by yourself to reduce the cost of going out for maintenance. Because the large motors and couplings used in the well are relatively large in size and the surrounding space is narrow, it is very difficult and time-consuming to disassemble the motor couplings on site. Contents of the invention [0003] In order to solve the above-mentioned...
