Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments the utility model, be elaborated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of brake of the present utility model;
Fig. 3 is the side-looking structural representation of the utility model one embodiment;
Fig. 4 is the side-looking structural representation of another embodiment of the utility model.
Embodiment
As shown in Figure 1, a kind of lifting motor structure, comprises magneto 1100 and brake 1200.
Wherein, as in Figure 2-4, brake 1200 comprises brake disc 1210, armature 1220, yoke 1230, spline housing 1240 and hand release 1250.
Brake disc 1210, armature 1220 and yoke 1230 arrange from front to back successively with one heart.Brake disc 1210 is with spline housing 1240 by spline engagement, and the end cap 1110 of the end face of this brake disc 1210 and magneto 1100 is affixed, and spline housing 1240 is connected with the axle 1120 of magneto 1100.Between armature 1220 and yoke 1230, be provided with spring 1260, yoke 1230 is provided with solenoid 1270.
Brake disc 1210 by and motor end face 1110 between produce frictional force and pass to motor shaft 1120 by spline housing 1240 and make motor braking.
Armature 1220 can lateral movement or lateral movement forward under the elastic force of spring 1260 backward under the attraction of solenoid 1270.
Outside armature 1220 and brake disc 1210, be provided with a circle dirt-proof boot 1290, can prevent that dust from entering.
The straight way 1232 that the rear side of yoke 1230 has chute 1231 and the footpath that is connected with this chute 1231 extends internally, the external diameter of chute 1231 reduces from front to back gradually.
Hand release 1250 is in transmission connection with brake disc 1210, and it comprises release board 1251, sliding pearl 1252 and brake handle 1253.
When the solenoid 1270 in yoke 1230 is switched on, under the effect of electromagnetic force, armature 1220 is attracted to yoke 1230, and brake disc 1210 is released, and in release condition, meanwhile, spring 1260 is pushed in compressive state by armature 1220.
When magneto 1100 breaks down power-off, solenoid 1270 dead electricity, armature 1220, no longer by magnetic attraction, under the restoring force effect of spring 1260, makes armature 1220 tops to brake disc 1210, makes magneto 1100 brakings.
When maintenance has a power failure, can carry out manual releasing by hand release 1250, braking is removed.
Particularly, the moving brake handle 1253 of layback drives release board 1251 to be subjected to displacement to rear side backward, and then can drive brake disc 1210 to leave motor end face, and braking is removed.
, brake handle 1253 is screwed in above-mentioned slideway from tapped through hole 1251b meanwhile, the sliding pearl 1252 in slideway is moved in slideway, sliding pearl 1252 is snapped in straight way 1232, brake 1200 maintains braking disarm state, without manpower, continues to force in brake handle 1253, laborsaving convenience.
Be understandable that, as shown in Figure 3 and 4, the profile of release board 1251 can be circle, also can be greater than the arc-shaped edges of semi arch and a straight flange by one surrounds and forms, now, release arm 1251a is positioned at the top of arc-shaped edges, and so the moment of brake handle 1253 when pulling has been shortened in design, more laborsaving.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, to the variation of the above embodiment, modification, all will drop within the scope of claims of the present utility model.
