Description
Technical field
The utility model relates to elevator technology field, relates in particular to manual unlocking device outside a kind of elevator cage door lock Room.
Background technology
GB specifies that the sill line of lift car and well enclosure can not exceed certain distance, but the gate that car door lock is housed is not subject to the restriction of this distance.Constantly have in recent years the safety misadventure of taking off door in elevator sedan-chair in service to occur, elevator is equipped with car door lock becomes current trend simultaneously.
The effect of gate lock is, in the time that elevator move or in the time of non-leveling zone, in locking state, prevents from taking off in passenger's sedan-chair and the danger that causes opening gate, and can in sedan-chair or sedan-chair, open gate in the time of leveling zone.Layer door mainly drives and opens the door and close the door in the time of flat bed by gate at present, work as elevator power failure, in sedan-chair, there is people to fall in a swoon or when engineering staff need to enter car, and car is just in time at leveling zone, door cutter and layer door lock roller are just in time in being associated state, Room door can only be opened a segment distance by triangular key, stretch out one's hand again and enter in this gap, pull open gate lock by stirring corresponding mechanism, the subsequent action such as open the door again, general this generic operation all carries out in the less region of crack between a door and its frame, when as wider in people's hand, may not stretch in this region and operate, there is inoperable risk, be outside the leveling zone Room, to be difficult to open Room door and gate, now need a kind of Room door of can directly pushing open outside the Room to make the method for gate lock release solve problems.
Existing applicant has applied in undelegated patent, as shown in Figure 1 to Figure 2, outside the Room, release principle is: when elevator is during at leveling zone, and elevator power failure, rescue group need to enter car and rescue people, and now layer door lock roller 1 enters between two of the left and right fork 2,3 of Men Daoqu.First open layer door one segment distance with triangular key insert layer door triangulation chain, observing car behind this layer of position, continue to open layer door, now layer door lock roller 1 will move in company with layer door, it is static that gate keeps, in the time that layer door lock roller 1 continues horizontal motion, by contact door cutter left swing bar 2 and promote left swing bar and rotate counterclockwise around left cramp bar axle center, left swing bar 2 drives driving lever 4 to rotate counterclockwise around upper support bar axle center simultaneously, driving lever 4 is also rotating around left swing bar articulated section when upper support bar axle center rotates counterclockwise, in the process of its rotation, there is a horizontal motion components left, this horizontal motion is enough to stir the vertical component of latch hook 5 and makes left-hand revolution, do release action, rotate counterclockwise after certain angle around left cramp bar axle center at left swing bar 2, when latch hook 5 lifts completely, left swing bar 2 will touch backing pin, stopped by backing pin, left swing bar no longer rotates, then promote backing pin, backing pin drive door cutter together with gate to left movement, realization is opened the door.
But there is following shortcoming in this structure:
1. when each switch gate, cramp bar moves with door cutter left swing bar, and action radius span is large.
A cutter left swing bar and driving lever by three swing arms (two left sides are associated arm and a cramp bar) structure be associated base connect and can together with rotate, synchronism require high.
3. the three arm type structure of gate latch hook, processing technology difficulty, cost is high.
4. complex structure, the difficulty of avoiding interference in design is large.
5. the vertical component length of gate latch hook is greater than the length of drive part.When this makes to rescue outside the Room, the horizontal throw of left-hand door cutter fork must be greater than the horizontal throw of right door cutter fork.And order is when opening gate from the Room, the progressive error of gate and the Room door when progressive error of Room door and gate is greater than sedan-chair inward swinging door.
6. a cutter left swing bar and driving lever are by three swing arm structures, and while making switch gate, the bearing load of the left swing arm of left-hand door cutter fork and driving lever, cramp bar increases, and is unfavorable for the life-span of device.
7. a cutter left swing bar and driving lever be by three swing arm structures, Installation and Debugging difficulty, if adjust badly, three swing arm structures are easily stuck in motion process.
8. cramp bar is taking the driving lever of right half as cantilever fine strain of millet, easily beat, and structural stability is not good enough.
9. while rescue outside the Room, be to rely on the cliding friction of driving lever and gate latch hook vertical component to realize, repeatedly action is is easily worn and torn driving lever flange, and latch hook can easily fall paint because wearing and tearing, and more easily under wet environment, gets rusty, and reliability reduction makes to unblank.
