Abstract

The utility model discloses an elevator brake, which comprises a casing, an end cover, a magnet yoke, an electromagnetic coil, armature and a buffer spring. At least two blind holes are uniformly processed on the inner planar face of the end cover, each blind hole is provided with an inner mute post for buffering and muting, and the lengths of the mute posts are larger than the depths of the blind holes. The elevator brake adopts the designs of the blind holes and the mute posts which are all easy to process and lower in cost and further well achieve the purpose of buffering and muting.

Description

A kind of elevator brake

Technical field

The utility model relates to electric controlled brake device, is specifically related to a kind of elevator brake.

Background technology

When elevator brake moves, the armature bump end cap of brake inside, send very big noise, this does not meet the requirement to noise of elevator control, therefore on end cap, process circular groove, be embedded buffer gasket and reach the purpose of slowing down impact and noise reduction, but the circular groove processing difficulties, cost is higher, and the productive costs of buffer gasket is also higher in addition.

The utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of processing simple and easy, lower-cost elevator brake.

For achieving the above object, the technical solution of the utility model is: a kind of elevator brake, comprise housing, end cap, yoke, magnet coil and armature, evenly be processed with at least two blind holes on the inner side plane of described end cap, be equiped with the quiet post that is used to cushion with noise reduction in described blind hole, the length of described quiet post is greater than the degree of depth of described blind hole.

Preferably, the inboard of described end cap is that the center is processed with a circular flat bottom groove with the axis of armature, and described armature end face is processed with the boss with described circular flat bottom groove coupling.

Preferably, the boss of described armature is provided with magnetism isolating spacer.

Preferably, also be arranged with recoil spring on the described armature.

Preferably, be provided with the brake equipment of two groups of symmetries in the described elevator brake housing along axis, every group of brake equipment all comprises end cap, yoke, magnet coil and armature.

Adopt the beneficial effect of the technical program to be: adopt the design of blind hole and quiet post, blind hole and quiet post all are easy to processing, and cost is lower, has well reached the purpose of buffering and noise reduction again.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Embodiment, as Fig. 1, Fig. 2 and shown in Figure 3, a kind of elevator brake, comprise housing 11, end cap 1, yoke, magnet coil 2, armature 3 and buffering spring 6, on the inner side plane of end cap 1 evenly processing promptly on same circumference at interval 120 degree be processed with 3 blind holes 13, in blind hole 13, be equiped with the quiet post 12 that is used to cushion with noise reduction, the length of quiet post 12 is greater than the degree of depth of blind hole 13, be arranged with magnetism isolating spacer 31 on the end face of armature 3, housing 11 and end cap 1 bolted connection, housing 11 is connected with elevator bolt, also is provided with the release axle 62 and the release lever 61 of locking elevator brake when maintenance, and the connection box 4 that the pig-tail wire of magnet coil is installed.

Principle of work is, be installed in elevator brake on the drg of elevator hoist with bolt, the output shaft of its armature 3 is connected on the push rod of drg, so that can promote the slipper and the friction lining of push rod release the brake, when elevator stops, the magnet coil dead electricity of elevator brake, armature 3 is in initial position under the pressure of holding spring tightly of elevator band-type brake, the brake plate of elevator brake and friction lining are also held elevator tightly and are dragged the wheel hub that draws motor holding tightly under the pressure of spring, elevator is braked, when elevator need move, magnet coil 2, yoke generates an electromagnetic field, armature 3 overcomes the application force of holding spring tightly under the effect in magnetic field, promote the push rod of braking, overcomes the application force of holding spring tightly, make brake plate and friction lining unclamp elevator and drag the wheel hub that draws motor, elevator brings into operation.When maintenance, rotate release lever 51, drive release axle 52 and rotate, discharge axle 52 corresponding surfaces and become arc surface by the plane in armature 3, in the groove that arc surface embedding armature 3 is provided with, thereby with armature 3 lockings, to prevent the drg misoperation.

Adopt the design of circular flat bottom groove 14 and boss 32 separate unit stage structures, it is fast to have a big-movement of energising suction, impacts the low characteristics of little noise during release, has simple in structurely, and it is reliable to be swift in motion.

Wherein, quiet post can be two, four or more, and its material can be rubber, plastics or nylon etc., and the effect of magnetism isolating spacer 31 is when magnet coil 2 dead electricity, but armature 3 at high speed demagnetizations are moved rapider.

Wherein, be provided with the brake equipment of two groups of symmetries in the elevator brake housing 11 along axis, every group of brake equipment all comprises end cap 1, yoke, magnet coil 2, armature 3 and buffering spring 6, can realize that two armature 3 move to both direction respectively, be two-way push, to satisfy the needs of equipment.

The effect of recoil spring 6 is when magnet coil 2 dead electricity, when armature 3 is pushed back under holding the application force of spring tightly, plays the effect of buffering, in order to avoid damage drg.

Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
