The specific embodiment
To shown in Figure 5, door lock of elevator of the present invention is used for elevator door or gate, comprising such as Fig. 1: door lock assembly, the locked component of locking elevator door, guarantee door-closing in-place assembly, electric switch;
Door lock assembly comprises pedestal 5, dead bolt 1, dead bolt guide 8,9, closes lock spring 10, is arranged at respectively the lockhole on the two fan elevator doors 2,3; Dead bolt 1 is arranged on the pedestal 5, and the afterbody of dead bolt 1 connects an end that closes lock spring 10, and the other end that closes lock spring 10 is captiveed joint with pedestal 5; The both sides of dead bolt 1 are respectively equipped with dead bolt guide 8,9, dead bolt guide 8,9 is fixedly installed on the pedestal 5, dead bolt guide 8,9 can lead to the sense of motion of dead bolt 1, and dead bolt 1 can only sway and can not move up and down under dead bolt guide 8, the restriction of 9 guiding; Lockhole on the elevator door 2,3 is aimed at the head of dead bolt 1; Door lock assembly is used for directly locking elevator door 2,3.
Locked component comprises locking piece 4, locking spring 11, is arranged on the lift car or the control mechanism 411 of stop side; Locking piece 4 is connected with pedestal 5 by axle, and locking piece 4 can be around this axle rotation; The back of locking piece 4 is connected with pedestal 5 by locking spring 11; Control mechanism 411 can make locking piece 4 rotations;
Locking piece 4 comprises guide wheel 41, ratchet 42, and when control mechanism 411 acted on guide wheel 41, locking piece 4 clickwises made ratchet 42 leave the bayonet socket of dead bolt 1, make the locked component release; When control mechanism 411 leaves guide wheel, and locking spring 11 is when acting on guide wheel 41, locking piece 4 left-hand revolutions, make ratchet 42 snap in the bayonet socket of dead bolt 1, this moment, locked component was in the lock state, and dead bolt 1 is locked, thereby made door lock assembly keep the positive lock state.
Locked component is used for keeping door lock of elevator to be in the lock state.Control mechanism 411 can be re-pack (or cam mechanism), also can be electromagnetic control mechanism.Control mechanism 411 leaves or is pressed into the bayonet socket of dead bolt 1 by controlling ratchet 42, locked component is switched between the locking and unlocking two states.Whether the locking of locked component does not change the state of door lock assembly, and locked component does not change the lock-out state of elevator door when elevator moves.
Guarantee that the door-closing in-place assembly comprises sliding pin 6,7, sliding pin retracing spring 12,13 with lockhole, is fixedly installed on the block 17,18 on the elevator door 2,3;
The head of pedestal 5 is provided with guide groove, and slidably sliding pin 6,7 is arranged in the guide groove; Sliding pin 6,7 connects respectively sliding pin retracing spring 12,13;
Guarantee that the door-closing in-place assembly makes door lock assembly only when elevator door closing puts in place, its dead bolt 1 can be realized the locking to elevator door.
Electric switch comprises the door contact that is arranged on each elevator door 2,3, the lock contact that is arranged at dead bolt 1 head; Electric switch is used for confirming that elevator door closing puts in place and all lockholes of dead bolt 1 insertion elevator door are realized door locks locking.
Each fan door of elevator door is provided with door contact; The number of the lock contact on the dead bolt 1 equates with the sum of the door contact of elevator door.
Elevator door as shown in Figure 1 is center opening door, and door contact 14 is set on the elevator door 3, and door contact 14 has two, is door contact 14a, 14b, two door contact 14a, 14b and elevator door 3 insulation but be interconnected.
Door contact 15 is set on the elevator door 2, and door contact 15 has two, is door contact 15a, 15b, two door contact 15a, 15b and elevator door 2 insulation but be interconnected.
Lock contact 16 on the dead bolt 1 has four, is lock contact 16a, 16b, 16c, 16d, locks contact and dead bolt 1 insulation for these four, and 16b is communicated with 16c.
The process that the present invention unblanks, opens the door is as follows:
When elevator cab movement to flat bed zone, the control mechanism 411 of (or stop side) contacts and pushes open guide wheel 41 with the guide wheel 41 of locking piece 4 on the car at this moment, guide wheel 41 moves to right under the effect of control mechanism 411, makes ratchet 42 leave the bayonet socket of dead bolt 1, realizes the release of locked component;
Dead bolt 1 is imposed to the right power (as making the dead bolt 1 stressed by the modes such as handle or electromagnet are set at dead bolt 1), dead bolt 1 overcomes the elastic force that closes lock spring 10 and moves right under the effect of external force, leave respectively elevator door 2,3 lockhole, and sliding pin 6,7 lockhole, realize the unlatching of elevator door; Meanwhile door contact 14a, the 14b of electric switch, 15a, 15b break away from lock contact 16a, 16b, 16c, 16d respectively, thereby disconnect the electric loop take contact 16a and 16d as end points.
After dead bolt 1 leaves sliding pin 6,7 lockhole, when elevator door is opened, along the guide groove on the pedestal 5 outwards mobile two side shiftings of dead bolt 1 (namely to), sliding pin 6,7 blocks dead bolt 1 and makes door lock assembly be held open state sliding pin 6,7 simultaneously under sliding pin retracing spring 12,13 effect.Therefore sliding pin 6,7 only can guarantee that dead bolt 1 just can carry out the locking of elevator door when elevator door closing puts in place; When elevator door not during door-closing in-place, dead bolt 1 is stopped by sliding pin 6,7 and can not lock elevator door.
The present invention closes the door, the process of locking is as follows:
Elevator door 2,3 cuts out and when moving to certain position under external force, and the block 17,18 on the elevator door 2,3 moves inwardly into sliding pin 6,7 afterbody and contacts; Elevator door 2,3 continues in the mobile process, promotes sliding pin 6,7 and moves inward together (namely close to dead bolt 1) with elevator door 2,3 mobile blocks 17,18; When elevator door closing puts in place, the lockhole of sliding pin 6,7 heads is just aimed at the head of dead bolt 1 and elevator door 2,3 lockhole, dead bolt 1 is moved to the left under the effect of closing lock spring 10, dead bolt 1 pass sliding pin 6,7 lockhole and and then insert lockhole on the elevator door 2,3, realize the locking of elevator door; Meanwhile, door contact 14a, the 14b of electric switch, 15a, 15b contacts conducting with lock contact 16a, 16b, 16c, 16d respectively, and consist of the series loop that is communicated with take contact 16a and 16d as end points, thereby affirmation door-closing in-place and locking are finished; Then elevator operation, the control mechanism 411 of (or stop side) separates with guide wheel 41 on the car, and locking piece 4 is left-hand revolution under the effect of locking spring 11, and ratchet 42 is snapped in the bayonet socket of dead bolt 1, realizes the locking of locked component.
The present invention can realize the positive lock of elevator door.
