Description
Technical field
It the utility model is related to elevator components technical field, and in particular to a kind of Novel car door locking based on asynchronous door knife
Device.
Background technology
Elevator becomes increasingly to be unable to do without in daily life, is not used only in high-rise residential building and office building, low
Installation in layer residential building or private villa is also more and more, the thing followed, the security of elevator also just become especially
It is important.
In the elevator accident of the State Bureau of Quality Supervision's statistics, it is due to personnel's blindness in elevator faults in sedan-chair to have very big proportion
Caused by saving oneself.Provided in standard GB/T 7588-2003：Elevator shaft inner surface and car sill, carriage door frame or
The horizontal distance at the nearest doorway edge of sliding door should install car door lock additional.It is even more to propose to open non-in newest No. 1 modification file
When locking generation elevator faults in region, the passenger in carriage cannot should completely open gate, prevent trapped person and fall
The risk of hoistway.But when carriage is in onlocking zone, then require gate to be fully opened in sedan-chair or outside the Room,
Get rid of poverty rapidly so as to fulfill personnel in sedan-chair.
At present, due to the design feature of asynchronous door knife, it is desirable to a trip that gate first moves link again layer door enabling.Cause
This, it is relatively more to be configured using the car door lock of asynchronous door knife separately from door knife, and require to pacify on each layer door gear
Fill one and hit bow, this undoubtedly adds additional the difficulty and failure rate of installation and debugging for the higher elevator of floor；
The car door lock of the asynchronous door knife of other is integrated on a knife, although eliminating the attachment device of layer door gear, due to it
Latch hook is positioned only at active door tool arm side, and when being parked in when elevator faults in onlocking zone, rescue personnel cannot lead to outside the Room
Cross layer croquet and open gate, it is thus impossible to rapidly make trapped person get rid of poverty.
How to overcome the problem of asynchronous door knife is in use installation process, be to be currently needed for solving the problems, such as.
Utility model content
The problems of the purpose of the utility model is to overcome existing asynchronous door knife use in car door lock.This practicality

The right side of the swing arm latch hook 11 is provided with steel wire rope component 15, the steel wire rope of the steel wire rope component 15 vertically to
Lower extraction, when artificially pulling the steel wire rope, the latch hook portion of swing arm latch hook 11 rotates down, and takes off the latch hook portion of swing arm latch hook 11
Off-hook plate 12, by the artificial manual unlocking of car door lock.
Preferably, the right side of swing arm latch hook 11 is additionally provided with contact contact pin 14, and the hook plate is provided with switch 13, is putting
When the latch hook portion of arm latch hook 11 is meshed with hook plate 12, the insertion of contact contact pin 14 switch 13, the lock of generation verification car door lock
Tight signal, can be according to whether signal be locked in triggering, to judge whether car door lock locks.
Below according to Fig. 2 and Fig. 3, the Novel car door locking based on asynchronous door knife that the utility model is discussed in detail fills
The operation principle and the course of work put：
When gate is in enabling region, during normally-open gate and layer door, the motor driving synchronous belt of door machine drives door machine
Door knife bottom plate 1 on hanging plate is moved to enabling direction, since layer croquet is among left-hand door tool arm 2 and right door tool arm 10, and is arrived
Both distances are equal.At this time, the directive wheel 9 on left-hand door tool arm 2 moved together therewith is close to roll on curve ruler 8, certainly
Under the pulling force of the gravity of body and the first tension spring 6, track that left-hand door tool arm 2 is set according to 8 curved surface 801 of curve ruler（Tilting section）Start
The bottom clockwise；Meanwhile right door tool arm 10 will walk one section of idle stroke until touch a layer croquet, right door tool arm 10 is by push layer
Croquet unlocks layer door lock, and at this time, layer croquet also gives reaction force to right door tool arm 10, promotes its upper pendulum clockwise, gate
After continuing a trip, right 10 clockwise oscillation of door tool arm drives swing arm latch hook 11 to rotate clockwise, and departs from its latch hook portion
Hook plate 12, until the tool arm bending edges 1001 of right door tool arm 10 are contacted with the rubber tip 17 of door knife bottom plate 1, right door tool arm 10 will not
Swing again, and at this time, left-hand door tool arm 2 also swings to down the horizontal position of the first pivoted arm 7 and no longer swings, in left-hand door tool arm 2 and the right side
Gripping layer door croquet under the collective effect of door tool arm 10, drives layer door to open together.
When gate is in door opening state, elevator respond other floors when calling ladder together, it is necessary to close gate and layer door, left-hand door
Tool arm 2 and right door tool arm 10 drive layer croquet move together to shutdown direction, and when shutdown will be in place, directive wheel 9 is along curve
Curved surface 801 on plate 8, which rolls, lifts left-hand door tool arm 2, abscission layer croquet, and gate continues to close the door until layer door door-closing in-place, right
Door tool arm 10 progressively disengages a layer croquet, and under the pulling force effect with the second tension spring 16 of conducting oneself with dignity, right 10 counter-clockwise swing of door tool arm
Drive swing arm latch hook 11 to rotate, the latch hook portion of swing arm latch hook 11 is meshed with hook plate 12, at this time, the insertion switch of contact contact pin 14
In 13, send gate in place and locking signal, elevator runs to next stop.
When gate is in enabling region, during Lift out of order, when gate is in enabling region, during Lift out of order,
The outer rescue personnel of gate is first opened layer door with triangular key, when running into left-hand door tool arm 2 in layer croquet opening process, makes left-hand door
2 stress counter-clockwise swing of tool arm is lifted up, and is driven 3 pushing tow of the second pivoted arm to open block 4 and is moved upwards, link right door tool arm at this time
10 clockwise oscillations, so that swing arm latch hook 11 acts and unlocks car door lock, gate is opened in then linkage, rescue trapped person or
Passenger takes off door out of sedan-chair in person's sedan-chair, only need to take off the retentivity that a power overcomes motor（No more than 300N）Gate can be opened, behind
Action with normal condition open gate as layer door.
When gate is in non-enabling region, if Lift out of order, when passenger takes off in sedan-chair, at this time, gate first acts band
Move right door tool arm 10 to start to move, due to not having the stop of layer croquet in traveling process, right door tool arm 10 remains at initially
The latch hook portion of position, i.e. swing arm latch hook 11 is in engagement all the time with hook plate 12, continues to move to a distance rear-swing arm latch hook
11 latch hook portion is caught on hook plate 12, and gate is in locking state, and passenger cannot then open gate, it is therefore prevented that unexpected to occur.
Gate is implemented to pull downward on steel wire rope component 15 during rescue, rotates down the latch hook portion of swing arm latch hook 11, disengages it from hook plate
12 unlock car door lock, then open gate, rescue trapped person.
In conclusion the new cage door locking apparatus based on asynchronous door knife of the utility model, rational in infrastructure, cost is manufactured
Low, stability is high, judges onlocking zone using layer croquet, when elevator faults and when being in non-unlocking district domain, can prevent from multiplying
Objective blindness is dangerous caused by saving oneself；When rescue personnel, which reaches, elevator is stopped at onlocking zone, rescue personnel can then pass through layer
Croquet quickly opens gate, passenger is got rid of poverty, and clever structure is safe, has a good application prospect.
