For solving the excessive problem of moment pulling force that elevator braking is suddenly caused, can also be on car reload buffer brake equipment again, but car stoppage in transit position is difficult to control, if car is parked between the two layers of floor, then can cause " closing the people " phenomenon, bring another kind of potential safety hazard.
The purpose of this utility model is that a kind of lift car flat bed retaining means will be provided, and is intended to further improve the safety performance of elevator, eliminates the car degeneration situation generation that breaks and cause because of the traction flexible steel wire.
Another purpose of the present utility model is that a kind of lift car flat bed retaining means will be provided, when being intended to make the brake equipment generation action of elevator, guarantee that car can be parked in nearest first floor aspect reliably, cause " closing the people " accident to take place thereby eliminate elevator optional position stoppage in transit under emergency rating.
The later-model purpose of this reality is achieved in that lift car flat bed retaining means, and described car bottom is provided with energy disperser, it is characterized in that also being provided with on the described elevator installation frame:
An electromagnetic actuator that links to each other with the elevator governor circuit is accepted the impulse singla that governor circuit sends and is produced an adhesive action when elevator overspeed moves;
A dead bolt that links to each other with the action component of described electromagnetic actuator also is provided with returning spring between the stationary parts of described dead bolt and electromagnetic actuator;
A blocking seat is located on the framework rotationally, and, after upwards turning an angle, described blocking seat locked by described dead bolt.
And a limiting stopper that is arranged on the framework, when changeing when falling, blocking seat make it remain on horizontality downwards.
Also be provided with operating spring on the described framework, so that described blocking seat is pushed away fast after breaking away from dead bolt.
Described car bottom also is provided with the recovery device that makes described blocking seat return to primitive age state.
This structure, during the car normal operation, blocking seat is in position upwards, and at this moment, dead bolt withstands blocking seat makes it remain on this state; When the motion of car hypervelocity, the elevator governor circuit sends an impulse singla, and electromagnetic actuator produces an adhesive action, drive the dead bolt upward movement, change downwards after the blocking seat freedom, limited is blocked when going to level attitude, when car fell, energy disperser dropped on this blocking seat.Set the installation site of lift car flat bed retaining means, car just in time is parked on this floor face.This shutdown feature promptly all is equipped with above-mentioned flat bed retaining means at every layer in hierarchical control, guarantees that car can drop on the flooring of nearest one deck.Returning spring makes dead bolt be returned to the state of stretching, extension, it can be pinned again when blocking seat upwards rotates.
Therefore, lift car flat bed retaining means of the present utility model has improved the safety performance of elevator effectively, eliminates the car degeneration situation generation that breaks and cause because of the traction flexible steel wire.Simultaneously, owing to realized automatic leveling, thereby also eliminate elevator optional position stoppage in transit under emergency rating and cause " closing the people " accident to take place.It is simple in structure and safe and reliable, is particularly useful for residential lift.
This structure also is provided with operating spring on the described framework, so that described blocking seat is pushed away after breaking away from dead bolt fast, increased responsiveness of the present utility model.
