Description
Technical field
The present invention relates to the elevator technology field, especially relate to the device of control turnover elevator cab door.
Background technology
Be to guarantee the safe operation of elevator, the safety device that control turnover elevator cab door is set is necessary, particularly seems particularly important during greater than 0.15m when the distance between elevator hoistways inside face and the car sill; This has clear statement in national standard, GB7588-2003 standard 11.2.1 regulation: the distance between elevator hoistways inside face and the car sill should be greater than 0.15m, if car is equipped with the door of mechanical interlocking and can only opens in the district of unblanking, above-mentioned spacing is unrestricted; Because when elevator is not unblanking to distinguish et out of order or power failure and when out of service, passenger in the lift car can open car door by force and escape, but also do not know car is in what position passenger's this moment, because above-mentioned distance, can the passenger be damaged, more dangerous is: when elevator faults recovers or sends a telegram here car door door-closing in-place malfunctioning switch again, at this moment elevator can restart operation, causes bigger personal injury even brings life danger to the passenger; The applicant once declared the utility model patent that a key name is called " elevator car door locking device " for this reason, grant number: CN2763234Y, in this patent, be to adopt hitting to bend and contact on the bumping wheel and being fixed on layer door gear in the hanging hook assembly be fixed on the door opener cross girder, the action of triggering electric switch, and the car door lock is opened; This device has been realized the normal run switch door of elevator is had no effect preferably, and when elevator was out of service unblanking to distinguish et out of order or power failure, the passenger can open car door voluntarily and escapes in the car; And do not unblanking to distinguish et out of order or power failure and when out of service, the passenger then can't open car door and go out when elevator, thereby unlikely meeting accident; But run into following situation sometimes: when elevator faults occurs in the district of unblanking, and the passenger be old man or child, unablely takes off door in car, therefore produces fear, even diseases induced; Be to shorten passenger's wait time, need possess the function that to open the door outdoors from layer, so that rescue fast.
Summary of the invention
The objective of the invention is deficiency at above-mentioned prior art, a kind of elevator car door locking device is provided, there is asynchronous door opener elevator successively the opening time that it is applicable to all layers door and car door, makes it to have following function: the one, and can auto-unlocking when elevator normally moves; The 2nd, elevator faults is shut down not in the district of unblanking, and the passenger can not open elevator car door locking device; The 3rd, shut down unblanking to distinguish Lift out of order, the passenger can push car door aside in the car and unblank; The 4th, shut down unblanking to distinguish Lift out of order, and the passenger is unable when taking off, after the rescue group can open layer door lock with key, push layer door aside and open a car door lock.
For achieving the above object, technical scheme of the present invention is such: a kind of elevator car door locking device, comprise the adapter plate that is installed on the door opener link plate, rotary middle spindle is hinged on movable latch hook on the adapter plate, be arranged on the roller on the movable latch hook, be arranged on the fixedly latch hook on the door opening machine for elevator upper sill frame, reset and stop gear, secondary door cutter, and be arranged on layer door roller on the layer door hanging plate; Said movable latch hook matches with fixing latch hook; The roller that is provided with on the movable latch hook forms with secondary door cutter and can contact connection with the translation of car door with respect to layer door roller; Said secondary door cutter is two that be arranged in parallel, waits long connecting rod and adapter plate to be hinged with two of secondary door cutter pivotallys attached respectively by two ends, and wherein a connecting rod is hinged coaxial on adapter plate with the hinged and movable latch hook of adapter plate; Said layer door roller can stretch between two secondary door cuttves, contacts with secondary door cutter with layer door parallel motion; Said reset and stop gear is fixed on the adapter plate, and contact connection with movable latch hook, wherein be provided with spring, realize resetting with elastic force.
Working process of the present invention is such: at normal operating condition, movable latch hook and fixedly latch hook be closed, the car door lock can't be opened; Have only to the district of unblanking, get final product onlocking zone, the energy auto-unlocking, this moment, layer door roller entered between two secondary door cuttves, along with the door opener action, door opener link plate parallel motion is installed in also translation one segment distance of adapter plate on the door opener, and secondary door cutter contacts with a layer roller, because of layer door is static relatively, layer door roller blocks pair door cutter, and adapter plate is wanted translation with the door opener link plate, is arranged on the roller on the movable latch hook, because of the centre of gration of movable latch hook is hinged on the adapter plate, the centre of gration of movable latch hook is with in the adapter plate translation, and this roller is blocked by secondary door cutter, and forcing movable latch hook is that axle rotates with the centre of gration, movable latch hook breaks away from fixedly latch hook, car door is opened, and a following layer door lock cutter that just is fixed is opened, and layer door driven by car door and open; At closing time then adapter plate with the reversing sense translation of door opener when opening the door, roller on the removable pin hook is blocked by the secondary door of another root cutter, forcing movable latch hook is that axle rotates with the centre of gration, reset and the stop gear mating reaction under, movable latch hook and fixing latch hook closure; When elevator hinders when being parked in onlocking zone for some reason, door opener is out of service, and the passenger opens the car door lock by pushing car door aside, its principle of unblanking during with normal operating condition auto-unlocking identical; When elevator hinders when being parked in outside the onlocking zone for some reason, thus the time layer door roller do not enter between two secondary door cuttves, a secondary door cutter can not contact with layer door roller, the car door lock can't be opened; When elevator hinders when being parked in onlocking zone for some reason, the unable again car door of pushing aside of passenger, after the rescue group can open layer door lock with key, push layer door aside a segment distance, before layer door lock roller on the door opening machine for elevator structure does not also touch a cutter, the layer door roller of this device touches secondary door cutter earlier, and promotion is arranged on the roller on the movable latch hook, this moment is not because car door also moves, and movable latch hook is static relatively, under the promotion of secondary door cutter, movable latch hook rotates along centre of gration, the car door lock is opened, and layer door lock roller contacts the door cutter then, and car door tegillum door drives to be opened.
Owing to adopted technique scheme, a kind of elevator car door locking device of the present invention, automatic blocking and auto-unlocking in the time of being implemented in elevator and normally moving; Elevator faults is shut down not in the district of unblanking, and the passenger can not open elevator car door locking device; Shut down unblanking to distinguish Lift out of order, the passenger can push car door aside in the car and unblank; Shut down unblanking to distinguish Lift out of order; and the passenger is unable when taking off; after the rescue group can open layer door lock with key; push layer door aside and open multiple functions such as car door lock; especially overcome the prior art elevator when unblanking to distinguish the et out of order shutdown, can not open the door outdoors from layer and implement the defective of rescue fast.
