Description

Large-scale motor coupling dismounting device

Technical Field

The utility model relates to the technical field of coupling dismantling equipment, in particular to large-scale motor coupling dismantling equipment.

Background

In the mining industry, the entire mineral lifting system and the mineral conveying system all adopt large motors as power sources. These large motors are typically connected to the actuator via a coupling, and because of the relatively large size of the motor, the size and weight of the coupling associated therewith are correspondingly increased. In the actual production and use process, because the underground mine space is small, the underground mine is basically impossible to be provided with a crane, therefore, when the coupler is disassembled and replaced, only the mode of manually taking out the coupler flange from the motor spindle by manually utilizing a hammer can be adopted for disassembly and assembly, the disassembly and assembly work efficiency is low, the disassembly and assembly difficulty is high, and the labor intensity is high.

For the situation, the patent with publication number CN213005060U discloses a movable motor coupler dismounting device, which utilizes a lifting mechanism to adjust the heights of a top pressing head and a counter-pulling mechanism, and is suitable for the coupler dismounting work with different mounting heights. In addition, the coupler can be effectively pulled out from the motor spindle by utilizing the cooperation of the pushing head and the counter pulling mechanism, so that the labor intensity of workers for dismounting is reduced, and the convenience of dismounting the coupler is improved. However, in this solution, the disassembled motor can only be a horizontal motor placed horizontally, and for some motor couplings installed abnormally, this solution is difficult to be adequate, especially for some couplings driven by non-coaxially. If the non-coaxial transmission coupler which is unconventionally installed is dismounted by adopting the technology, a worker is required to lift the whole dismounting device and adjust the angle, then the counter pulling mechanism is buckled on the back surface of the coupler, the whole operation process is very troublesome, meanwhile, the underground mine space is smaller, the operator is difficult to vacate enough space to lift the whole dismounting device, and the operation difficulty is increased.
