Description
Technical field
The present invention relates to a kind of elevator brake shock absorption device, particularly a kind of elevator brake is without wearing and tearing air buffer.
Background technology
Drg is the important safety device of elevator, it safe, be reliably one of key factor ensureing elevator safety operation.Normally, drg has two and acts on greatly, and the first can make operating elevator when cutting off the electricity supply automatically car stop; Its two be elevator out of service time, drg should be able to ensure in the rated load situation of 125%, make car keep static, invariant position.
Existing elevator brake, as shown in Figure 1, is comprised the electromagnet 1 and armature 2 that are connected by guiding mechanism, is fixed with brake rubber block 3 on the right side of armature 2 by Connection Block.For avoiding brake noise and avoiding the gouging abrasion of electromagnet 1 and armature 2, usually between electromagnet and armature, cushion blocking can be set up.
But existing cushion blocking, is elastomeric material substantially, after the long-time repeated compression of Rubber shock-absorbing pad, can follows the string, thus lose shock-absorbing function.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provide a kind of elevator brake without wearing and tearing air buffer, without wearing and tearing, air buffer is ingenious utilizes the air in cavity to carry out damping to this elevator brake, good damping effect, fiduciary level is high, after long-time use, still there is good shock-absorbing function, long service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of elevator brake is with without wearing and tearing air buffer, and for the bumper and absorbing shock in drg between electromagnet and armature, it comprises compression plug, check valve and sealing locking plug; Transverse groove is provided with in described armature; Compression plug is arranged between electromagnet and armature, and compression plug comprises cock cap, the first Compress Spring and stopper rod, and one end of stopper rod is stretched in transverse groove, and the other end of transverse groove is provided with the second groove, is disposed with check valve and sealing locking plug in this second groove; Check valve, between stopper rod and transverse groove, form the cavity of an inner filling air; Second groove can seal by sealing locking plug, and the center of sealing locking plug is provided with the air extractor vent that can be connected with cavity, and the keying of this air extractor vent is controlled by described check valve; First reseting spring sleeve is contained on the stopper rod that is positioned at outside cavity, and the reseting elasticity of the first retracing spring is greater than the crack force of check valve.
The armature of contiguous described electromagnet side is provided with the first groove connected with cavity, and described first retracing spring is arranged in the first groove.
The second retracing spring is provided with in the check valve of contiguous described cavity side.
It is contact sliding block joint between the stopper rod of described compression plug and transverse groove.
After the present invention adopts said structure, there is following beneficial effect:
1. ingeniously utilize the air in cavity to carry out damping, good damping effect, fiduciary level is high, long-time use after, still there is good shock-absorbing function, long service life.
2. compression plug is arranged between electromagnet and armature, can repeat pressurized.When compression plug pressurized, the air compressing in cavity, plays cushioning effect, has a small amount of gas to flow away from stopper rod; When distress resolves, the first retracing spring work.Make cavity internal gas pressure be less than ambient pressure, the reseting elasticity due to the first retracing spring is greater than the crack force of check valve, and check valve is opened, and air flows into cavity from air extractor vent through check valve, supplements the gas run off in cavity.First retracing spring can ensure that the gas gross in cavity is constant, prevents gas leakage in cavity, also namely avoids because compression plug is sunk and lose shock-absorbing function.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete better embodiment, the present invention is further detailed explanation.
As shown in Figure 1, a kind of elevator brake, comprises electromagnet 1, armature 2 and brake rubber block 3.
Electromagnet 1 is connected with Bringing-back mechanism 5 preferably by guiding mechanism 4 with armature 2.
Brake rubber block 3 is coaxially fixed on the right side of armature 2 preferably by Connection Block 6.
As depicted in figs. 1 and 2, a kind of elevator brake, without wearing and tearing air buffer, for the bumper and absorbing shock between electromagnet in drg 1 and armature 2, can substitute existing cushion blocking.
