Description
Technical field
The present invention relates to a kind of elevator brake damping device, particularly a kind of elevator brake is delayed with without abrasion air
Flushing device.
Background technology
Brake is the important safety device of elevator, and the safe and reliable of it is the key factor for ensureing elevator safety operation
One of.Normally, brake has two big effects, one is can make operating elevator when cutting off the electricity supply automatically car
Stop；The second is when elevator is out of service, brake should ensure that in the case of 125% rated load, car is set to keep quiet
Only, position is constant.
Existing elevator brake, as shown in figure 1, including the electromagnet 1 and armature 2 that are connected by guiding mechanism, in rank
The right side of iron 2 is fixed with brake rubber block 3 by connecting seat.Ground for the collision that avoids brake noise and avoid electromagnet 1 and armature 2
Damage, it will usually between electromagnet and armature, set up beam.
However, after existing beam, essentially elastomeric material, Rubber shock-absorbing pad long-time repeated compression, can follow the string,
So as to lose shock-absorbing function.
The content of the invention
The technical problem to be solved in the present invention is to be directed to above-mentioned the deficiencies in the prior art, and provides a kind of elevator brake and use
Without abrasion air buffer, the elevator brake is subtracted with without the abrasion ingenious air using in cavity of air buffer
Shake, good damping effect, reliability is high, after long-time use, still with preferable shock-absorbing function, long service life.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of elevator brake is with without abrasion air buffer, for the buffering in brake between electromagnet and armature
Damping, it includes compression plug, check valve and sealing locking plug；Transverse groove is provided with the armature；Compression plug is arranged on electromagnetism
Between iron and armature, compression plug includes cock cap, the first compression spring and stopper rod, and one end of stopper rod is stretched into transverse groove, transverse groove
The other end be provided with the second groove, be disposed with second groove check valve and sealing locking plug；Check valve, stopper rod with
The cavity of an internal filling air is formed between transverse groove；Sealing locking plug can be sealed the second groove, sealing locking
The passage for being provided centrally with cavity to be connected of plug, the keying of the passage is controlled by the check valve；First
Reseting spring sleeve is mounted on the stopper rod being located on the outside of cavity, and the reseting elasticity of (the first back-moving spring is more than the opening force of check valve.
The first groove connected with cavity is provided with the armature of the neighbouring electromagnet side, described first resets bullet
Spring is arranged in the first groove.
Second back-moving spring is provided with the check valve of the neighbouring cavity side.
It is slidably connected between the stopper rod and transverse groove of the compression plug for contact.
The present invention has the advantages that using after said structure：
1. the ingenious air using in cavity carries out damping, good damping effect, reliability is high, after long-time use, still has
There are preferable shock-absorbing function, long service life.
2. compression plug is arranged between electromagnet and armature, it can repeat to be pressurized.When compression plug is pressurized, the air in cavity
Compression, plays cushioning effect, has a small amount of gas to be flowed away at stopper rod；When distress resolves, (the first back-moving spring work.Make cavity
Interior air pressure is less than ambient pressure, because the reseting elasticity of (the first back-moving spring is more than the opening force of check valve, opens check valve,
Air flows into the gas being lost in cavity, additional cavity body from passage by check valve.(the first back-moving spring ensure that cavity
Interior gas gross is constant, prevents gas leakage in cavity, namely avoids and lose shock-absorbing function because sinking compression plug.
