Description

Elevator cage door lock unlocking apparatus and elevator
Technical field
The present invention relates to elevator technology field, particularly relate to a kind of elevator cage door lock unlocking apparatus and elevator.
Background technology
According to relevant regulations, the sill line of lift car and well enclosure can not exceed predetermined distance, but the gate of car door lock is housed then not by the restriction of this distance, the safety misadventure of taking off door in constantly having elevator to run in recent years in sedan-chair occurs, and elevator is equipped with car door lock becomes a kind of trend simultaneously.
General elevator cage door lock, when having people to fall in a swoon in elevator power failure, sedan-chair or engineering staff needs to enter car, and car is just in time at leveling zone, just in time to be in be conjunction state for door cutter and Room door lock roller, can only open Room door one segment distance by triangular key, but due to the distance opened very little, rescue group is often difficult to stretch out one's hand the tripper moving car door lock to and is opened by gate, delay rescue time, reduce the success ratio of rescue, finally cause the generation of safety misadventure.
Summary of the invention
The object of the present invention is to provide a kind of elevator cage door lock unlocking apparatus, this device is simple to operate, quick, greatly shortens the time of opening gate from the Room.
Another object of the present invention is to provide a kind of elevator being convenient to rescue.
For realizing object of the present invention, the technical scheme taked is:
A kind of elevator cage door lock unlocking apparatus, comprise a cutter base plate, fork, draw-bar seat, pull bar, retracing spring, stay cord, pulley mechanism, gate latch hook, door cutter base plate is provided with draw-bar seat, fork and pulley mechanism, retracing spring two ends are conflict draw-bar seat and pull bar respectively, stay cord one end is connected with pull bar, the other end is walked around pulley mechanism and is connected with gate latch hook and provides power to make it rotatable to gate latch hook, fork is located between pull bar and pulley mechanism, and the side of fork along enabling direction be located at by pull bar.
When having people to fall in a swoon in elevator power failure, sedan-chair or engineering staff needs to enter car, and car is just in time at leveling zone, and now door lock quiet roller in the Room is in door cutter region.The door lock of Room door is first opened by triangular key, toward the promotion Room, both sides door, door lock quiet roller in the Room moves with Room door, after Room door opens certain distance, door lock quiet roller in the Room is touched fork and is promoted fork and moves together, thus gate can be driven to move a very little segment distance, before fork does not touch pull bar, gate latch hook and lock are still in engagement, gate can not be fully opened, now continue toward the promotion Room, both sides door, under the effect of the quiet roller of Room door lock, pushing drawing rod moves along enabling direction by fork, one end of stay cord cylinder lever connecting rod is moved along enabling direction together along with pull bar, the other end of stay cord connection gate latch hook is walked around pulley mechanism and is moved up, thus drive gate latch hook to be rotated upwardly to depart from lock, realize the unlatching of gate.The side of fork along enabling direction be located at by pull bar, can not action when not needing to unblank outside the Room, ensures the safety of elevator.For general elevator, this device is simple to operate, quick, do not need by other instruments, when utilizing existing enabling, door lock quiet roller in the Room promotes fork and acts on this device along the action of enabling direction movement, directly gate is opened from the Room, greatly shorten the time of opening gate from the Room, improve success ratio when rescuing and work efficiency.Gate latch hook and pull bar are provided with retracing spring and latch hook spring respectively, after the power of extruding fork removes, deformation can be recovered by the spring compressed, thus promotion Room door moves toward closing direction, and fork is to Room door power, add the self-closing power of Room door, improve the probability that Room door lock is closed.
Below technical scheme is further illustrated:
Be further, described pulley mechanism comprises the first fixed pulley, be positioned at the second fixed pulley above the first fixed pulley and the 3rd fixed pulley, one end of stay cord is connected with pull bar, and the other end walks around the first fixed pulley successively, the second fixed pulley, the 3rd fixed pulley are connected with gate latch hook.When one end that stay cord is connected with pull bar is moved along enabling direction, first fixed pulley, the second fixed pulley and the moving direction of the 3rd fixed pulley to stay cord change, the other end that stay cord is connected with gate latch hook moves up, thus gate latch hook is rotated upwardly to depart from lock, realize the unlatching of gate.
Further, pulley mechanism at least comprises a fixed pulley, and the top of pull bar and gate latch hook is located at by fixed pulley.
Further, stay cord is non-telescoping stay cord, ensures that the mutual motion of pull bar, stay cord, gate latch hook is responded fast, reaches the object of quick release.
Further, draw-bar seat has through hole, pilot bar one end is fixed on pull bar, and the other end passes described through hole and matches with through hole, and described retracing spring is sheathed on pilot bar, and retracing spring two ends are conflict pull bar and draw-bar seat respectively.Pilot bar plays the effect of location to the retracing spring be sheathed on pilot bar, prevent retracing spring from deflecting when deformation in compression, thus retracing spring only can be moved at pilot bar axial direction, when retracing spring is compressed, pilot bar one end can be stretched out in the through hole of draw-bar seat.
Further, elevator cage door lock unlocking apparatus also comprises latch hook spring, and latch hook spring one end is connected with door cutter base plate, and the other end is connected with gate latch hook.When pull bar moves compression reseting spring along enabling direction; stay cord drives gate latch hook to rotate up; gate latch hook upwards compresses latch hook spring; latch hook spring applies a downward pressure to gate latch hook; gate latch hook applies a downward pulling force to connected stay cord; after pulley mechanism; the other end that stay cord is connected with pull bar applies one along opening the door reciprocal pulling force to pull bar; thus prevent pull bar quick travel from causing retracing spring to exceed by the limit compressed, retracing spring is played to the effect of protection.Otherwise retracing spring also plays the effect of protection to latch hook spring.
The present invention also provides a kind of elevator, comprise gantry crane plate, Room door, the quiet roller of Room door lock, lock hook shaft, gate latch hook, lock, elevator cage door lock unlocking apparatus, elevator cage door lock unlocking apparatus is arranged on gantry crane plate, the connection location of stay cord and gate latch hook is arranged at the side of lock hook shaft near lock, gate latch hook is connected on a cutter base plate by lock hook shaft rotationally, gate latch hook matches with lock, and Room door is fixedly connected with the quiet roller of Room door lock.
Room door both sides parallel motion to the left and right under the effect of external force, the quiet roller of Room door lock be fixedly connected with Room door with Room door along enabling direction parallel motion, door lock quiet roller in the Room promotes fork and moves along enabling direction, fork moves a certain distance rear pushing drawing rod along enabling direction parallel motion, one end that stay cord is connected with pull bar is moved along enabling direction with pull bar, the other end that stay cord is connected with described gate latch hook is moved up by pulley mechanism, gate latch hook departs from lock along with stay cord is rotated upwardly to around lock hook shaft, and gate realizes opening.
