The principle of work of this towing machine:
Start: after motor stator energising, rotor is at magnetic field force move under influence, and magnetic brake work system swing arm is opened simultaneously, makes traction sheave depart from braking, thus drives elevator cage lifting;
Stop: while motor stator power-off, the push rod of magnetic apparatus shrinks, and make arcuate brake sheet move toward one another under the effect of elastic force, hold traction sheave tightly, traction sheave stops operating under the effect of friction force, thus makes elevator cage stop lifting.
The replacing of each vital parts of this towing machine:
Removable bearing on outer end cap: by the bolt be arranged in Special fixing machine structure is rotated up, make arc and contact bottom traction sheave and give certain predetermincd tension, traction sheave is supported fixing, the brake control lever on both sides is also locked to brake wheel direction by the adjusting bolt that simultaneously comes loose, in case spline and rotating shaft skew, realize can carrying out field maintemance without the need to fixing lift car, unclamp coder can be removed by fixing mesopore is tightened up a screw, again the bearing seat bolt of rear end plate be fixed in the middle part of outer end cap is unclamped, the bearing fixed seat that bearing is housed can be unloaded afterwards, again bearing 11a is taken out from bearing fixed seat, change new bearing, again the bearing fixed seat that new bearing is housed to be loaded in outer end cap and bolt of rear end plate locking can be realized the on-the-spot dismounting of bearing,
Traction sheave: slough steel wire rope after first being fixed by lift car, unclamp adjusting bolt 22 and the brake control lever on both sides locked to brake wheel direction thus brake wheel is fixed, when after dismounting outer end cap, only the lock bolt that traction sheave is connected with brake wheel outer edge need be removed the dismounting that can realize traction sheave, new traction sheave is replaced with, again outer end cap is installed, unclamp adjusting bolt 22 and both sides brake control lever is returned to former scale and be loaded on the replacing that steel rope can complete traction sheave;
Stator: by being removed by the horizontal lock bolt 18 of cylindrical shell perimembranous, can will be equipped with the cylindrical shell of stator and side cover unload, then replaces with new stator is housed;
Rotor: traction sheave and brake wheel are fixed by Special fixing machine structure, after the cylindrical shell that stator is housed is removed, rotor cover locking nut is removed, rotor cover can be unloaded from rotating shaft together with rotor, again new rotor and rotor cover are loaded onto, locking jam nut, thus realize the replacing of rotor;
, be there is skew rotation to prevent tearing shape process shaft open, thus realize can safeguarding without the need to fixing lift car in another removable bearing: traction sheave and brake wheel radial direction are fixed by Special fixing machine structure; After cylindrical shell and side cover are unloaded, jam nut is unloaded rim body and rotor are unloaded from roller end again, by bearing seat and bearing are removed from the bearing seat of supporting seat frame by special tool, then another the removable bearing be arranged in bearing seat pulled down and be fit in bearing seat after replacing with new bearing, the bearing sleeve that replaces with new bearing is fixedly connected with bearing seat in rotating shaft, thus the on-the-spot dismounting realizing another removable bearing is safeguarded, afterwards the rotor of dismounting and side cover are reinstalled back on supporting seat frame.
The above, be only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit originally make invention, any those skilled in the art do not depart from the content of technical solution of the present invention in every case, make any simple amendment, impartial change and modification, all should belong to covering scope of the present invention according to technical spirit of the present invention to above embodiment.
