Description
Technical field
Integrated car door lock synchronous door knife device of the present invention, belongs to elevator technology field.
Background technology
Increase regulation in new national standard newly：Car applies the power of 1000N when outside onlocking zone at enabling limits device,
Gate is opened no more than 50mm, and this requirement is not referred in GB GB7588-2003.Required in new national standard " not close to
The place of stop " is that the requirement to prevent power for taking off door is 1000N in non-unlocking district domain, and gate unlatching must not exceed 50mm；Meanwhile,
This is anti-to take off door gear and at stop, specialist tools can not be used from stop side at " in onlocking zone " with layer door linkage
Can open and prevent taking off door gear.This newly-increased regulation requirement car door device takes off device using anti-.
At present, the car door locking device that in the market is used and door lock device generally non-Unitary.Independent car door lock
Device is installed on gate hanging plate, while increase a croquet for unlocking gate latch hook in hall door side or hit bow, so as to prevent sedan-chair
Door gear pushs gate aside in non-unlocking district domain from cab interior.However, independent car door locking device and door lock device are to gate
Structural requirement it is higher, car door lock and door lock device are installed simultaneously on car door device, can Existential Space interference, debugging difficulty etc. it is all
Many problems.Meanwhile, need to increase tripper on every door gear layer by layer, increased substantial amounts of cost.
At present, in the market also has the door lock device for integrating door knife and car door lock, such as published application number
A kind of elevator cage door lock of 201010120775.4 inventions, in the range of onlocking zone, baffle plate and car door lock are not interfered now
As, but when elevator is located at non-unlocking district domain, baffle plate and latch hook are interfered, it is impossible to open gate.In addition, some one
Formula car door lock uses electromagnetic principle, it is only powered in the case of could realize that latch hook is opened, unfailing performance is relatively low.Also adopt in addition
With synchronous door knife structure, synchronous door knife complex structure, fault rate are higher, and synchronous door knife is very smart to installation site requirement
Really, installation difficulty is increased, reliability is difficult to be guaranteed.
The content of the invention
Instant invention overcomes the deficiency that prior art is present, there is provided integrated car door lock synchronous door knife device, by door knife

Lock driving lever 23, is provided with the arc-shaped side coordinated with unblock driving lever 23 on the lock hook assembly 6, the lock hook assembly 6 is by unblock
Driving lever 23 realizes rotation to stirring for arc-shaped side, so that the latch hook 9 positioned at the end of lock hook assembly 6 lifts hook or off the hook.
Specific work process：
Normally-open gate and layer door process be：After cage operation is as layer door sustained height, layer croquet is located at left tool arm 21
And right tool arm 31 between, floor door is normally-open, and external door machine actuating device causes that swing rod 41 is rotated down, now, position-limited wheel
51 passively roll into the stopper slot 412 of swing rod bottom from the upper stopper slot 411 of swing rod, define the movement position of swing rod 41, now
10 one-tenth tensioning states of torsion spring on gag lever post 51.
Connecting rod 42 is moved downward due to the rotation of swing rod 41, so as to pull upper connecting rod 7 to rotate, due to upper connecting rod 7, under
Connecting rod 8 and 32 one-tenth quadric chains of left redundant tool arm 22 and right redundant tool arm, therefore left redundant tool arm 22 and right redundant tool arm 32
Drawn in inner side, so as to drive left tool arm 21 and right tool arm 31 to draw in, while gathering, layer croquet is clamped；Because unblock is dialled
Bar 23 is located on left tool arm 21 and right tool arm 31, therefore unblock driving lever 23 is moved, and unlocks the arc of driving lever 23 and lock hook assembly 6
Side coordinates so that lock hook assembly 6 is rotated so as to open latch hook 9, and after latch hook 9 is opened, layer croquet drives whole device to opening
One lateral movement, so as to complete door opening action.
Normal switching-off gate and layer door process be：Likewise, when being closed in external door phase, due to left tool arm 21 and right knife
Still in the state of gripping layer croquet, therefore layer croquet drives whole device to medial movement to arm 31, to moving to closing position
Afterwards, external door machine actuating device rotational swing rod 41, makes swing rod 41 be rotated to a high position from low level, during rotation, gag lever post 52
Moved upwards due to the effect of stage clip 10, so as to move to the upper stopper slot 411 of swing rod from swing rod bottom stopper slot 412, together
When define the continuation campaign of swing rod 41.
Now, upper connecting rod 7 returns to horizontal level by the motion of swing rod 41, left tool arm group 2 and right tool arm group 3 playback to
At maximum spacing.
When leveling zone anon-normal hold-open door is taken off from outside the Room：Layer croquet is located between left tool arm 21 and right tool arm 31, from outside the Room
Layer croquet to the left draw close by tool arm 21 when taking off, and left tool arm 21 is subject to the extruding of layer croquet and phase left redundant tool arm 22 is moved, now
10 one-tenth compressive states of torsion spring, in the presence of a power is persistently taken off, the arc on unblock driving lever 23 and lock hook assembly 6 on left tool arm 21
Shape side coordinates, meanwhile, quadric chain causes that right tool arm 31 coordinates also by unblock driving lever 23 with arc-shaped side, and latch hook 9 is lifted therewith
Rise, so that lock hook assembly 4 is opened completely, realize Room gate linkage..
When leveling zone anon-normal hold-open door is taken off from car：Layer croquet is located between left tool arm 21 and right tool arm 31, from sedan-chair
Layer croquet to the right draw close by tool arm 31 when being taken off in door, right tool arm 31 by layer croquet extruding and phase right redundant tool arm 32 is moved,
Now 10 one-tenth compressive states of torsion spring, in the presence of a power is persistently taken off, on unblock driving lever 23 on right tool arm 31 and lock hook assembly 6
Arc-shaped side coordinate, meanwhile, quadric chain causes that left tool arm 21 coordinates also by unblock driving lever 23 and arc-shaped side, latch hook 9 with
Lift so that lock hook assembly 4 is opened completely, realize Room gate linkage.
During non-unlocking district domain：There is no layer croquet between left tool arm 21 and right tool arm 31 now, therefore unblock cannot be driven to dial
Bar 23 is moved, and cannot also drive lock hook assembly 6 to rotate, so as to gate and layer door cannot be opened.
Embodiments of the invention are explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned implementation
Example, in the ken that those of ordinary skill in the art possess, can also make on the premise of present inventive concept is not departed from
Go out various change.
