Description
Technical field
The invention belongs to elevator car safety technical fields, and in particular to a kind of elevator brake using double brake system
And its braking method.
Background technology
At present, elevator applications are more and more extensive, so that needing safety device to guarantee personal safety.Traditional elevator system
Dynamic device is generally electromagnetic brake, by compressed spring, braking electromagnetic mechanism, brake scotch, braked wheel, transmission and adjustment mechanism etc.
Composition.Its cardinal principle is by generation during electromagnetic coil power on/off or loses electromagnetic attraction, to control the action of armature, with
Achieve the purpose that braking.It is widely used in today of people's daily life in elevator, people gradually start to pay attention to elevator operation
Safety and comfort, and the failure of brake can cause elevator car slipping, Huo Dun bottom of rushing to summit, it is therefore necessary to prevent brake
Failure, it is ensured that elevator brake performance safety is reliable.
Elevator brake there are the problem of can be divided into two aspect：1. electric information problem；2. mechanical problem.
Electric type problem is mainly poor contact of contacts or the adhesion of control brake, off and on, causes brake shoe and system
It rubs and wears between driving wheel, generate brake force failure.
Mechanical problem mainly includes：Mechanical card resistance causes brake that can not close a floodgate or close a floodgate slowly after powering off；Braking
Spring leads to its insufficient pressure, causes brake force insufficient due to being used for a long time；Armature installation is crooked in brake, causes to rub
Pad wear is serious, and contact area is less than 80% between braked wheel and friction plate, and brake force reduces；It tripping spring insufficient pressure and rubs
The problem of pad is worn is required for replacing tripping spring or friction plate, causes to dismount cumbersome；Electromagnetic coil there are remanent magnetism phenomenon,
It is opening a sluice gate moment, electromagnetic coil power, which is more than, closes lock tripping spring power, arrives at a station moment in elevator, and brake block cannot hold braking tightly,
Car car slipping accident easily occurs.And it is existing elevator brake that electromagnetic coil cannot be held tightly there are brake block caused by remanent magnetism phenomenon
The difficult point that device can not overcome.
Problems above causes the security and stability of brake poor.In order to make brake component intensity high, avoid installing
It is crooked, while larger braking moment can be provided and improve the reliability of brake, therefore develop a kind of double brake system
Elevator brake is significant for improving elevator brake performance and safety.
Invention content
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of elevator brake using double brake system and
Its braking method.
The present invention is realized using following technical scheme：
A kind of elevator brake using double brake system of the invention, including hydraulic pressure end cap, bolt of cover, brake arm, system
