Description
Technical field
A kind of bidirectional speed limiter is the utility model is related to, more particularly, to a kind of for elevator uplink and downlink overspeed protection
Bidirectional speed limiter.
Background technology
Limiter of speed is a part of elevator overspeed protecting device.Limiter of speed is arranged on computer room at the top of elevator, swelling device
In the melt pit of elevator bottommost, steel wire rope is looped around between limiter of speed and swelling device with closed loop, swelling device
So that steel wire rope is closely looped around in limiter of speed, move limiter of speed and elevator car timing synchronization.
Elevator overspeed is generally ascending for elevator or downstream rate exceedes more than 115% phenomenon of normal speed.Elevator surpasses
When fast, under centrifugal action caused by hypervelocity, the action of limiter of speed safety switch, elevator safety loop control car stop；Such as
There is car motion when not controlled by safety return circuit in fruit, and car continues to accelerate, and now limiter of speed can produce mechanical action, make
The rope sheave obtained in elevator governor stops operating, and speed limiter wire rope lifts the safety tongs voussoir for being installed on cage bottom, safety
Clamp voussoir and hold car guide rail tightly and produce brake, so as to by elevator stop by force.
The structure that existing bidirectional speed limiter typically continues to use original unidirectional limiter of speed realizes overspeed descending defencive function, therefore
Its overspeed descending defencive function is fairly perfect.But the realization of up defencive function generally requires to increase braked wheel, cause whole
Limiter of speed is oversized, causes the waste in space, is also made troubles to installation.Meanwhile when ascending for elevator exceeds the speed limit, may
Can not stir the tricing line of elevator brake mechanism because of braking moment deficiency caused by speed limited wheel rope, prevent elevator brake mechanism from
Action.People in the scalloping mode in governor rope race bottom typically by increasing rope sheave coefficient of friction, so as to increase limit
Braking moment caused by fast device rope sheave.The increase of this moment of friction is limited, in addition, with the abrasion of grooving otch, its
Coefficient of friction will reduce, so that braking moment caused by governor sheave reduces, larger hidden danger be present.
