Description
Technical field
The utility model belongs to underground coal mine provision for disengagement technical field, is specifically related to a kind of flame-proof electric motor detaching device for coupling.
Background technology
Underground coal mine flame-proof electric motor is mechanokinetic nucleus equipment, the factors such as because of the particularity of underground coal mine condition of work, there was dampness in the air, dust pollution, and flame-proof electric motor uses for a long time under these adverse circumstances, easily makes break down and damage, and impact is normally produced.In replacing or maintenance process, just motor coupling must be disassembled from rotor of output shaft axle.And shaft coupling and output shaft are that to closely cooperate be that hot charging is joined and has corrosion phenomena.Therefore demountor shaft coupling is a job of extremely wasting time and energy.
Usually the method adopted at present draws horse or Three-claw pull-horse with two pawls, during use, surely withstand axle head center hole by top for leading screw, adjustment pulling claw position, make to draw horse claw hook to be hooked in shaft coupling edge, rotating threaded shaft makes pulling claw drive shaft coupling edge outwards slide vertically and remove.But when pulling out shaft coupling, its edge of grabbing due to Three-claw pull-horse is too little, and contact surface is too little, Three-claw pull-horse discontinuity, easily occur breaking off relations even outside for shaft coupling edge damage phenomenon.Cause and both damaged equipment and extend the take-down time.
Utility model content
The utility model is wasted time and energy mainly for existing flame-proof electric motor dismounting coupling existence, to damage the problem of shaft coupling, is provided a kind of flame-proof electric motor detaching device for coupling.
The utility model is the technical scheme taked that solves the problem:
A kind of flame-proof electric motor detaching device for coupling, comprise flame-proof electric motor, the output shaft of flame-proof electric motor is provided with shaft coupling, wherein: also comprise fixed cross beam, two positioning tie bars, U-shaped chuck, jack and add long pin shaft, described one end of two positioning tie bars is flexibly connected with the two ends of fixed cross beam, the other end of two positioning tie bars is flexibly connected with the two ends of U-shaped chuck, and two positioning tie bars, fixed cross beam and U-shaped chuck composition rectangle structure, jack is arranged in rectangle structure, the base of jack is flexibly connected with fixed cross beam, the piston rod of jack with add long pin shaft and be flexibly connected.
The utility model adopts technique scheme, during use, the opening of U-shaped chuck is inserted on flame-proof electric motor shaft coupling from top to bottom, fixed cross beam is adjusted to the position consistent with shaft coupling centre-height, jack cylinder base is aimed at fixed cross beam to be placed on inside rectangular frame, add the front end alignment of long pin shaft one end and jack, the other end and flame-proof electric motor output shaft align, manually pull the pressure rod of jack fast, jack piston rod is slowly stretched out and withstands on flame-proof electric motor output shaft end, and then progressively pressurize with jack pressure rod, until motor coupler is removed on machine shaft.Again each parts are removed after finishing using and be placed in receiver.Therefore have the following advantages compared with existing provision for disengagement: the utility model disassembling device of motor coupler is simple to operate, easy, effectively reduce workload and the working strength of operating personnel; Removal efficiency is high, only needs a few minutes can complete motor coupler dismounting, substantially reduces the operating time, improve operating efficiency.The utility model disassembling device of motor coupler has good interchangeability, can be applicable to the motor coupler dismounting of different model motor.
