Background technology
In traditional elevator technology, brake apparatus includes three kinds, is respectively：Limiter of speed braking, rope brake braking and brake
Braking.Limiter of speed braking is the hypervelocity that limiter of speed is used to monitor and control at any time car, and cage operation speed exceedes specified speed
When spending certain value, limiter of speed and safety tongs linkage stop car.Rope brake braking is directly in traction steel wire by Braking
On rope, pass through the frictional force stop elevator car between rope brake and steel wire rope.The brake given in brake is as electricity
Terraced critical piece, undertakes the substantially all of braking maneuver of elevator operation, therefore brake is added in the prior art a variety of
Monitoring, is powered off immediately if accidental movement of elevator cage, and brake clamps hoist ropes, stop elevator car.
To sum up, existing brake device for elevator is in real work, limiter of speed braking, when car accidental movement but speed is not
During more than normal speed certain value, limiter of speed will not act stop car, therefore not be suitable for the braking of car accidental movement；Folder rope
Device is braked, and rope brake is acted directly on hoist ropes, and action is instantaneous to be completed, and impact is strong, especially acts and produces often very
Seriously beat, it is larger to rope clamping block and traction steel-cable damage after action；Brake, brake is electrical control, but
Brake troubles are mechanical jam mostly, even if power-off can not reach the purpose for preventing car accidental movement.
Thus, brake device for elevator of the prior art has braking effect poor, the shortcoming that device is easily damaged.
