Description
Technical field
The utility model relates to the elevator technology field, is specifically related to the integrated gate of a kind of elevator and locks asynchronous door lock device.
Background technology
The life to people of generally using of elevator has brought convenience, and meanwhile, the safety performance of elevator also receives publicity day by day.
In China's GB, stipulate: " horizontal throw at the edge, nearest doorway of elevator hoistways inside face and car sill, car door framework or sliding door should not be greater than 0.15m.If car is equipped with the door of mechanical interlocking and can only opens in the district of unblanking of floor door, except extraordinary circumstances, the locking of gate should be automatically depended in the operation of elevator, and gate locking must have electric safety device to confirm, above-mentioned spacing is unrestricted ".
In order to meet the requirement of GB, in prior art, usually at the hoistway inside face, add fender wall or independently gate lock is installed, avoid when Lift out of order, the passenger does not understand correct mean of escape, opens the gate escape, thereby causes danger.
But, the cost that fender wall is installed at the hoistway inside face is higher, and make elevator installation period prolongation, and being installed, locks independently gate, need to be at each storey setting release blade, this just need to harmonize accurately to the release blade of gate lock and each floor when lift-mounting, guarantee can both open accurately the gate lock at the release blade of each floor, when the too high situation of floor, car moves up and down and has unavoidably deviation, bring larger difficulty to the installation of the release blade of each floor, also make the fault rate of gate lock significantly increase simultaneously.
In prior art, the door cutter of elevator and gate lock great majority are to set up respectively, when mounted, need carry out the debugging that a cutter and gate lock coordinate, and not only efficiency is low, simultaneously, also can cause fault rate to increase.
The utility model content
The utility model provides the integrated gate of a kind of elevator to lock asynchronous door lock device, and elevator cage door lock and the set of asynchronous door cutter are arranged on gate, and Installation and Debugging are convenient, and safety performance is good.
The integrated gate of a kind of elevator is locked asynchronous door lock device, comprise and the relatively-stationary door of gate cutter base plate, and with the relatively-stationary track frame of car; Swing cutting blade and the release blade cooperatively interacted for driving layer croquet is installed on door cutter base plate; Be connected with the ball of griffing matched with the track frame on described cutting blade; Be hinged with latch hook on described door cutter base plate, relatively be fixed with the locking bolt fastened with this latch hook on car, described release blade is provided with for stirring the poke rod of latch hook with change and locking bolt mated condition; Also be connected with unlocking board on described door cutter base plate, be provided with the linkage part that cooperatively interacts to drive the unlocking board rotation between described cutting blade and unlocking board, described unlocking board is provided with the thumb wheel that rotates to stir the latch hook release with unlocking board.
The normal gate of opening with the process of layer door is: cage operation to layer door sustained height position after, layer croquet is between cutting blade and release blade, under the driving of door machine, gate is opened, the door cutter base plate be arranged on gate moves with gate, be arranged on release blade on the cutter base plate barrier effect lower swing at layer croquet, the poke rod promotion latch hook be fixed on the release blade lifts, remove the fastening state of latch hook and locking bolt, make a machine can drive gate to continue motion, in the process that continues motion, the cutting blade be arranged on a cutter base plate swings under the directional tagging of track frame, the common holding sheet croquet of cutting blade and release blade, driving layer door opens together.
Normally closing gate with the process of layer door is: under the driving of door machine, the gate motion, thereby cutting blade and release cutting blade clip are held layer croquet and are driven the motion of layer door, when door cutter base plate moves with gate, drive the release blade movement, the release blade is under the barrier effect of layer croquet, the lifting status that keeps latch hook, after moving to layer door and closing, layer croquet no longer moves, and the release blade swings and resets, and the poke rod on the release blade is removed the impetus to latch hook, latch hook resets and engages with locking bolt, completes closing of gate.
If at non-onlocking zone, be that gate and layer door are not to be positioned at sustained height, now between cutting blade and release blade, there is no a layer croquet, the release blade is due to the barrier effect that there is no layer croquet, can not swing, also just can not promote latch hook and lift, remove the fastening state of latch hook and locking bolt, gate and layer door all can't be opened.
When gate and layer door are positioned at sustained height, in the time of need to outside car, opening layer door, can promote cutting blade by layer croquet and carry out release, when layer croquet promotes the cutting blade motion, cutting blade drives the unlocking board rotation by linkage part, thumb wheel on unlocking board is stirred latch hook and is lifted along with the rotation of unlocking board, removes the fastening state of latch hook and locking bolt, realizes the unlatching of gate and layer.
As preferably, on described latch hook, with contact, on car, also relatively be fixed with described contact and match for sending the auxiliary contact of gate closing signal.
