Description
Technical field
The present invention relates to elevator technology field, relate in particular to a kind of elevator cage door lock unlocking apparatus and elevator.
Background technology
According to relevant regulations, sill line and the well enclosure of lift car can not exceed predetermined distance, but the gate that gate lock is housed is not subject to the restriction of this distance, constantly there is in recent years the safety misadventure of taking off door in elevator sedan-chair in service to occur simultaneously, elevator is equipped with gate lock becomes a kind of trend.
General elevator cage door lock, in the time having people to fall in a swoon in elevator power failure, sedan-chair or engineering staff need to enter car, and car is just in time at leveling zone, door cutter and Room door lock roller, just in time in being associated state, can only be opened Room door one segment distance by triangular key, but because the distance of opening is very little, rescue group is often difficult to stretch out one's hand to move to the tripper of gate lock gate is opened, 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 of being convenient to rescue.
For realizing object of the present invention, the technical scheme of taking 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, on door cutter base plate, be provided with draw-bar seat, fork and pulley mechanism, retracing spring two ends conflict respectively draw-bar seat and pull bar, 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, and fork is located between pull bar and pulley mechanism, and pull bar is located at the side of fork along the direction of opening the door.
In the time having people to fall in a swoon in elevator power failure, sedan-chair or engineering staff need 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.First open the door lock of Room door by triangular key, toward the promotion Room, both sides door, door lock quiet roller in the Room moves with Room door, Room door is opened after certain distance, door lock quiet roller in the Room is touched fork and is promoted fork and moves together, thereby can drive gate to move a very little segment distance, before fork is not touched 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, fork moves pushing drawing rod along the direction of opening the door, one end of stay cord cylinder lever connecting rod is along with pull bar moves along the direction of opening the door together, the other end of stay cord connection gate latch hook is walked around pulley mechanism and is moved up, thereby drive gate latch hook to rotate up to departing from lock, realize the unlatching of gate.Pull bar is located at fork along opening the door a side of direction, and the Shi Buhui action that do not need to unblank outside the Room, ensures the safety of elevator.For general elevator, this device is simple to operate, quick, need to be by other instruments, the action that while utilizing existing opening the door, the quiet roller promotion of Room door lock fork moves along the direction of opening the door acts on this device, from the Room, directly open gate, greatly shorten the time of opening gate from the Room, success ratio and work efficiency while improving rescue.On gate latch hook and pull bar, be provided with respectively retracing spring and latch hook spring, after the power of extruding fork removes, compressed spring can recover deformation, thereby promoting Room door moves toward closing direction, and fork is to power of Room door, increase the self-closing power of Room door, improved the probability of Room door lock closure.
Below technical scheme is further illustrated:
Be further, described pulley mechanism comprises the first fixed pulley, the second fixed pulley and the 3rd fixed pulley that are positioned at the first fixed pulley top, one end of stay cord is connected with pull bar, and the other end is walked around successively the first fixed pulley, the second fixed pulley, the 3rd fixed pulley and is connected with gate latch hook.In the time that move along the direction of opening the door one end that stay cord is connected with pull bar, the first fixed pulley, the second fixed pulley and the 3rd fixed pulley change the moving direction of stay cord, stay cord is moved up with the other end that gate latch hook is connected, thereby gate latch hook is rotated up to departing from lock, realize the unlatching of gate.
