Abstract
The utility model relates to a brake damping device. A brake is arranged at both sides of a friction disc of an elevator tractor and comprises a magnet yoke, an armature, a tongue plate arranged on the armature and a friction plate arranged on the tongue plate; the magnet yoke and the armature are arranged in parallel and a gap is reserved between the magnet yoke and the armature; a ring-shaped groove is arranged in the magnet yoke; a coil is sleeved in the ring-shaped groove; when the coil is powered on, the armature can be attracted by the magnet yoke and the friction plate is separated from the friction disc; when the coil is powered off, the magnet yoke releases the armature and the friction plate is attached to the friction disc; at least one shock pad is arranged in the magnet yoke; and the shock pad extends out of the shock pad and is contacted with the armature. According to the utility model, the vibration or noise generated when the armature is pulled back by the electromagnetic attraction force is alleviated and reduced by the arrangement of the shock pad; the brake damping device has a simple structure and a good damping effect; and the service life of each part of the brake can be effectively prolonged.
Description
Technical field
the utility model relates to elevator machine brake, particularly relates to a kind of drg shock absorption device.
Background technology
drg is the important safety device of elevator, it safe, reliably be one of key factor of guaranteeing elevator safety operation.What magnet stopper adopted usually is a built-in coil winding, through the energising or the dead electricity of coil winding, produces or lose electromagnetic force to produce action.
are along with the safety requirements of elevator improves constantly; A lot of magnet stoppers are when braking mode is changed into attracting state; Because of positive pressure needs a bigger electromagnetic attraction that armature is retracted greatly; Incident is exactly that bigger retracting shakes and noise, and long-term vibrations all can exert an adverse impact to each parts of drg.
Summary of the invention
the utility model purpose provides a kind of drg shock absorption device.
For achieving the above object, the technical scheme that the utility model adopts is:
a kind of drg shock absorption device; Described drg is arranged on the both sides of the friction disc of elevator traction machine; It comprises yoke, armature, is arranged on the hyoplastron on the described armature and is arranged on the friction lining on the described hyoplastron that described yoke and armature laterally arrange and leaves the gap, offer circular groove on the described yoke; Be arranged with coil in the described circular groove; When described coil electricity, described yoke can the described armature of adhesive, and described friction lining and friction disc are separated; When described coil blackout, described yoke discharges described armature, and described friction lining and friction disc fit; Be provided with at least one cushion blocking in the described yoke, described cushion blocking stretches out described yoke and contacts with described armature.
preferably, described cushion blocking is provided with 4.
preferably, are provided with retracing spring between described yoke and the armature.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
the utility model relaxes and subdues vibrations or the noise that produces when electromagnetic attraction retracts armature through shock pad is set, and it is simple in structure, and good damping effect can actv. prolongs service life of each parts of drg.
Description of drawings
accompanying drawing 1 is the structure cutaway view of drg in the utility model.
wherein: 1, drg; 2, yoke; 3, armature; 4, hyoplastron; 5, friction lining; 6, bolt; 7, circular groove; 8, coil; 9, cushion blocking; 10, setting nut; 11, retracing spring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
A kind of drg shock absorption device that
are as shown in Figure 1, drg 1 is arranged on the both sides of the friction disc of elevator traction machine.
drg 1 is general main to be comprised yoke 2, armature 3, be arranged on the hyoplastron 4 on the armature 3 and be arranged on the friction lining 5 on the hyoplastron 4, flexibly connects mutually through bolt 6 between yoke 2 and the armature 3 to be integral.Yoke 2 laterally arranges with armature 3 and leaves the gap, offers circular groove 7 on the yoke 2, is arranged with coil 8 in the circular groove 7.
Be provided with at least one cushion blocking 9 in
yoke 2; Cushion blocking 9 is provided with 4 in the present embodiment, and cushion blocking 9 stretches out yoke 2 and contacts with armature 3, simultaneously; Each cushion blocking 9 all is connected with control apparatus; Control apparatus is specially setting nut 10, and setting nut 10 is threaded in the yoke 2, and the end of setting nut 10 pushes against cushion blocking 9.
Be provided with retracing spring 11 between
yoke 2 and the armature 3, when retracing spring 11 can guarantee coil blackout, help armature 3 to carry out resilience.
produce electromagnetic force when coil 8 energising, make the yoke 2 can adhesive armature 3, and friction lining 5 is separated with friction disc under the induced effect of armature 3 hyoplastrons 4, the brake off effect; Electromagnetic force disappears when coil 8 outages, and yoke 2 discharges armature 3, and friction lining 5 fits with friction disc under the effect of retracing spring 11, promptly holds friction disc tightly and accomplishes braking.
cushion blocking 9 plays the effect of vibration damping in the adhesive of yoke 2 and armature 3 or dispose procedure in the utility model, avoid in motion process the influence that impulsive force produces each parts; Simultaneously, produce under the worn-down situation,, promote cushion blocking 9 unworn parts and prop up armature 3 forward, remain damping effect through threaded adjusting setting nut 10 at cushion blocking 9 control positioies.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
Claims (3)
1. drg shock absorption device, described drg is arranged on the both sides of the friction disc of elevator traction machine, and it comprises yoke, armature, is arranged on the hyoplastron on the described armature and is arranged on the friction lining on the described hyoplastron; Described yoke and armature laterally arrange and leave the gap; Offer circular groove on the described yoke, be arranged with coil in the described circular groove, when described coil electricity; Described yoke can the described armature of adhesive, and described friction lining and friction disc are separated; When described coil blackout, described yoke discharges described armature, and described friction lining and friction disc fit; It is characterized in that: be provided with at least one cushion blocking in the described yoke, described cushion blocking stretches out described yoke and contacts with described armature.
