This utility model additionally provides the operation method of above-mentioned elevator door-motor synchronization latching device, mainly includes that door machine is normal
The step of the step of enabling and door machine are normally closed the door, wherein,
The step of door machine normal door, comprises the following steps：
Step a1, elevator door-motor drive power transmission shaft 7 to move in upper arcuation waist type groove 29 by Timing Belt, 7 band of power transmission shaft
Dynamic kinematic link 6 rotates counterclockwise (with direction shown in Fig. 3 to face datum level), and in the presence of stop torsion spring 9, transmission
Connecting rod 6 is mutually abutted with the side of drive link 4 all the time；
Step a2, drive link 4 are rotated under the drive of power transmission shaft 7 counterclockwise, and left blade 2 is with right blade 3 in
The heart draws in, and after drive link 4 rotates 20 °, the distance between left blade 2 and right blade 3 A draws 46mm in by former 72mm；
Step a3, right blade 3 touch unlocking croquet on hall door door lock by hall door door-lock opening, left blade 2 and right knife
Piece 3 is stopped by unlocking croquet so that connected drive link 4 is stopped the rotation；
Step a4, power transmission shaft 7 are continued to run with elevator door-motor effect, and kinematic link 6 continues to rotate counterclockwise, unlocking axle
14 promotion unlockings re-pack and 15 and touch unlocking roller 16, and latch hook releases the engagement with dead bolt 22, and door machine drives hall door together
Open；
The step of door machine is normally closed the door comprises the following steps：
Step b1, stopping means 8 block Limit Bearing 13 in the presence of extension spring 12, and two blade of door knife remains folder
Tight croquet state；
Step b2, when closing the door to door-closing in-place, collision block 19 touches stopping means 8, is rotated stopping means 8, releases
With the fastening state of Limit Bearing 13；
Step b3, under 7 continuation of power transmission shaft effect, kinematic link 6 is rotated further, and the release torsion of stop torsion spring 9, will unlock
Re-pack 15 withdrawals, and then latch hook and the matching closure of dead bolt 22, and contact 20 is contacted with contact shoe 21, and gate lock loop is connected, together
When two blades open, discharge ball of locking a door, hall door loop of the door lock is connected.
In a preferred embodiment, the operation method of above-mentioned elevator door-motor synchronization latching device is also closed including elevator
People and car rescue step and elevator in door area close people and rescue step of the car in not gate area, wherein,
Elevator closes people and rescue step of the car in door area is：
Hall door is opened with triangular key in hall door side, left blade 2 is touched using unlocking croquet in hall door, then two blades are same
When open to both sides；Unlocking axle 14 promotes unlocking to re-pack 15 and to touch unlocking roller 16, and latch hook is released and engages shape with dead bolt 22
State, hall door drive elevator door-motor to open together；
Elevator closes people and rescue step of the car in not gate area is：
If car door sill is adapted to passenger is first released car, manual unlocking hall door with lading door dill height fall, and draws
Dynamic unlocking steel wire rope 23, unlocking manually to re-pack 24 rotates around connecting shaft 26, the 24 shake-up unlocking rollers 16 that re-pack of unlocking manually, latch hook
Releasing is engaged with dead bolt 22, can individually open gate, after the unlocking steel wire rope 23 that comes loose, the release torsion of reduction torsion spring 25, manually
Unlocking re-packs 24 resets, and latch hook is meshed with dead bolt 22 in the presence of the second stage clip 27.
In above-mentioned technical proposal, by the power transmission shaft 7 that is connected, driven shaft 28, drive link 4, kinematic link 6, with
And upper and lower two arcuations waist type groove so that there is before door-opened elevator guide's stroke：Drive link 4 is in upper arcuation waist type groove 29
Inside move a certain distance, drive link 4 rotates predetermined angle, determined whether positioned at door area in advance, and only when positioned at door area
Hall door can be opened, so that the used time is safer；Because of the presence of guide's stroke, when car is in not gate area, transmission connects
Bar 6 is abutted with 4 side of drive link all the time, and unlocking re-packs and 15 cannot trigger unlocking roller 16, and latch hook closure, gate completely cannot
Open；The operation method of elevator door-motor synchronization latching device has the elder generation that drive link 4 turns over 20 degree under door machine normal condition
Process is led, and kinematic link 6 is rotated under the effect of the first stage clip 17 in the state of door machine is out of service so that opened in hall door
