The method that elevator door unnormal unlocking human body stops, comprising:
(1), when the car of elevator is not at a certain stop, when the layer door of this stop adopts improper opening, because lift car does not arrive this layer, be located at optical, electrical, magnetic, the inductor of this layer or machinery to touch parts and can not start and stop actuating section action, arrester in or beyond elevator door is opened with layer door and is opened, gear, on improper layer doorway of opening, makes personnel enter, thus plays safety guard-safeguard effect;
(2), when a certain stop of elevator car arrives, lift car touches by optical, electrical, magnetic, inductor or machinery the obstruction actuating section action that parts start this stop, this obstruction actuating section starts the latch hook of arrester by connecting rod, latch hook is opened, latch hook is opened and can not be started arrester, arrester can not be opened, and thus there will not be and blocks, thus ensures that the normal use of elevator is unaffected.
Described layer door adopts improper opening to refer to that the position of opening not car arrival normal layer door of layer door is opened, and comprises following several situation: it opens the layer door one, on this stop because artificially using three angled spoon lock handles if any people; Two, mechanical breakdown is damaged as layer door lock and this layer of door actv. is not locked; Three, elevator breaks down out of service, and car ground is higher than the ground of this stop, and the passenger in car to push aside when car door and layer door are down jumped etc. and belongs to the improper situation about opening of elevator door.
Described obstruction part is the one wherein of automatic curtain, the folding railing of protection, grille guard, check cable, anti-skid plate.
Supporting elevator when being center opening door, it stops actuating section 1 and is located on the limit of side opening in the layer door of right side, stops part and is located on the limit of side opening in the layer door of left side; Supporting elevator when being side opening door, described obstruction actuating section, be located at layer door close after on limit by side opening in the shutter of doorframe, stop part be located at shutter close after on the doorframe limit that touches.
In described right side layer door side opening limit on be fixed with push rod contiguous block, push rod contiguous block is provided with push-rod hole, the left-hand end of rotating disk push rod is through push-rod hole, between the left-hand end of rotating disk push rod and push rod contiguous block, return spring is set, its return spring is Compress Spring, when layer door is closed, fixed block on the layer door of left side promotes push rod and promotes traffic cycle to the right and rotate clockwise, when revolve rotate in place after traffic cycle ratchet be stuck in traffic cycle pawl slot.
Described automatic curtain is vertically located at the right side of left side layer door, and the limit, termination of automatic curtain is provided with and starts nail, starts nail for outstanding axle.
Described protection railing is made up of one or more expansion link or folding rod, pipe assembly sized by described telescopic rod pipe, and mutual grafting is scalable, and its right-hand end is provided with and starts nail; Described folding rod termination is by folding shaft articulamentum yi word pattern, and folding rod can fold along folding shaft, and its right-hand end is provided with and starts nail.
Described check cable is made up of from coil spring a rope and rope, and the medial extremity of rope is connected with from coil spring, and the other end of rope is followed closely with startup and is connected, the rolling and rope can pull open or retract.
Described trip mechanism comprises electromagnet trip mechanism and mechanical trip mechanism, electromagnet trip mechanism comprises electromagnet and ratchet takes off mouth hook, actuating lever and the ratchet of electromagnet take off mouth and link up with and be connected, when electromagnet energising starts, ratchet takes off mouth hook and catches on mini-roundabout ratchet and the dropout of traffic cycle ratchet; Mechanical trip mechanism comprises and starts plate and ratchet and take off mouth hook, starts plate and is connected with lift car, and when lift car moves to layer door, startup plate is stirred ratchet and taken off mouth and link up with the dropout that moves right.
Principle of work of the present invention: when elevator door is normally opened, when elevator car arrives layer door, on this layer of door, " the human body arrester of elevator door unnormal unlocking " receives a signal, this signal can be light, electric signal, the wherein one of field signal or mechanical signal, receive signal, by control circui start electromagnet action or by mechanical conductive to mechanical trip mechanism, take off mouth by the ratchet on electromagnet or mechanical trip mechanism to link up with and catch on mini-roundabout ratchet and traffic cycle ratchet departs from mini-roundabout and traffic cycle respectively, the now instantaneous intercropping left-hand revolution of mini-roundabout, pull bar is action downwards immediately, the latch hook left-hand revolution blocking part is driven to break off relations, latch hook is caused to be in unhook state, now elevator door is opened, stopping part can not opening and launches with layer door, traffic cycle is opened along with layer door, utilize the release of the elastic force of the return spring on the left of rotating disk push rod, drive traffic cycle to make turning anticlockwise to reset, after putting in place, mini-roundabout ratchet is connected in mini-roundabout pawl slot again, when elevator door is closed, fixed block on the elevator door of left side touches the push rod on the layer door of right side and moves to the right, now because mini-roundabout ratchet is connected in the pawl slot of mini-roundabout ratchet, traffic cycle rotates clockwise and drives mini-roundabout servo-actuated, mini-roundabout rotates to drive on pull bar and carries, make latch hook return to latch hook and catch on the startup nail stopping part, when layer door is closed completely, when traffic cycle rotates clockwise 90 ° of angles, traffic cycle ratchet is connected in the groove of traffic cycle ratchet, the locking state of latch hook can be kept so firmly, when layer door is improper open time, because lift car does not normally put in place, the electromagnet or the mechanical trip mechanism that stop actuating section do not receive actuation signal, electromagnet or mechanical trip mechanism are not pulled open two ratchets, traffic cycle and mini-roundabout can not make left-hand revolution action, now pull bar is also held latch hook tightly and is maintained the state catching on the startup nail stopping part, open when layer door is improper, layer door band moveable lock hook pulls the startup nail stopping part, obstruction part is opened, the door opening of unnormal unlocking is blocked, thus prevention personnel enter this improper layer door of opening and crash in hoistway, realize the safety guard-safeguard to personnel.Elevator service personnel, because of need of work, is carried out improper when opening the operation of layer door, can be made it to depart from respectively in the groove of large and small rotating disk ratchet by pulling flexible cord or directly stirring two ratchets, thus remove this device block function.
Beneficial effect of the present invention: the new mode as a kind of innovation is invented, the present invention is in elimination elevator safety hidden danger, protection personal security aspect by implementing the method for blocking and providing a kind of human body arresting gear of elevator door unnormal unlocking on layer door, the casualty accident that can effectively prevent personnel from falling down from the building from elevator door, eliminates safe hidden trouble; Stop actuating section owing to being provided with and blocking part, making arresting gear structure simple, more easily reach the effect of obstruction; Owing to adopting mechanical type to stop structure, stop intuitive and reliable; Mechanical structure blocks part and does not start when elevator door is normally opened, stop part and launch to stop during unnormal unlocking, and reduce and cause wearing and tearing to cause the risk lost efficacy because acting frequently, stable performance is more safe and reliable.
