Description
Technical field
The present invention relates to a kind of asynchronous door knife assemblies of elevator cage door lock.
Background technique
Door knife is as the important component on elevator door-motor device, and there are two types of form, i.e., asynchronous door knife and synchronous door knifes.New
There is specific regulation to the unlatching of gate in the national standard of revision, if 1, elevator is parked in onlocking zone due to any, it should be able to
With the power for being no more than 300N in stop where carriage and carriage, gate and layer door are opened manually；2, in order to limit personnel in carriage
Gate is opened, elevator is parked in non-unlocking district domain, applies the power of 1000N at enabling limits device, and gate is opened no more than
50mm.So elevator door should have the function of to prevent taking off, and when carriage is in non-unlocking district domain, the people in carriage can not be by carriage
Door is pushed aside, and can not also open car door in the case where elevator door motor involuntary maneuver, and the elevator in non-stop is avoided to beat
Opening causes passenger that unexpected injury occurs.
The technical solution of asynchronous door knife, which is substantially on the basis of original asynchronous door knife structure to increase, prevents taking off latch hook.
The left tool arm and right tool arm of door knife are mutually indepedent, left tool arm and right tool arm all by specific mechanical structure with prevent that taking off latch hook is connected
It connects；The horizontal movement of left tool arm or right tool arm, which will drive, to be prevented taking off upwarping for latch hook, to achieve the purpose that car door lock unlocks, thus full
The anti-requirement taken off of gate in sufficient national standard.
To guarantee safety that elevator is normally run up and down, the spacing of door knife tool arm and layer croquet can generally be set in 8~
10mm, the distance of two layer croquets in the horizontal direction being installed on each layer of layer door lock are 7mm, and layer door lock is revolved around O point
Turn 7mm i.e. layer door lock and turned to by horizontal lockup state to upwarp unlocked state, layer door can be opened at this time.The left knife of asynchronous door knife
Arm or right tool arm horizontal movement a certain distance, typically no less than 3mm, then driven by specific mechanical structure and prevent taking off latch hook
Upwarping unlocks gate.
Action process of the asynchronous door knife in door machine door opening process is as follows: carriage first runs to onlocking zone i.e. leveling zone,
After gate drives asynchronous door knife to move horizontally 8~10mm under motor driven, right tool arm starts to encounter layer door lock and moves ball, gate after
Continuous to open, Men Daozai moves horizontally 10mm (i.e. the unlock of layer door lock swings the right tool arm unlock floating 3mm of 7mm+) complete layer door lock afterwards
Unlock, while car door lock unlock is completed in the floating of right tool arm, gate drives layer door to open together after unlock, and gate is than layer Men Duokai
18~20mm.Left tool arm is in the moving process of door knife, since under the effect of gravity, right tool arm falls against layer croquet.
Action process of the asynchronous door knife in door machine door closing procedure is completely opposite with door opening process.
Elevator is as the transit equipment for transporting passenger, and in building hoistway, elevator door is that passenger passes in and out carriage for long-term work
Unique passage.Under normal circumstances, the running environment very severe of elevator, as often being accumulated in the sill slot playing the guiding role
Dirt, solid foreign materials etc., the foreign matters such as dust often increase the running resistance of layer door, layer door are caused to be unable to complete door-closing in-place,
And door-closing in-place is completed in gate at this time.Above-mentioned layer door can not door-closing in-place the reason of there are also artificial blockings, such as key, thin object
Etc. being stuck at layer door.
Gate door-closing in-place and layer door can not door-closing in-place in the case where, since the safety return circuit of layer door lock does not connect
Logical, elevator device can be such that gate reopens；During gate is opened, gate latch hook can be fixed in the fixation in door machine
Lock is stuck, and gate never can not be opened in onlocking zone, leads to the generation for closing occurrences in human life event.Gate latch hook is fixed latch hook card
Dead reason is as follows: national standard, opens gate to limit personnel in carriage, applies 1000N's at enabling limits device
Power, gate are opened no more than 50mm, thus in the limiting case, when gate door-closing in-place, gate latch hook and fixed latch hook
Spacing be not more than 25mm；And under the non-door-closing in-place of layer door, for gate again in door opening process, asynchronous door knife realizes gate and layer
The moving distance of door unlock is at least are as follows: 16~20mm+7mm+3mm=(26mm~30mm).Therefore distance value is greater than gate latch hook
With the spacing of fixed latch hook, so gate latch hook and layer door lock hook will not all be forced to tilt, gate and layer Men Jun cannot achieve solution
Lock.
