Abstract

The utility model discloses an elevator landing door lock capable of preventing the accidents of falling in hoistways during the manually-operated opening of the elevator door. The elevator landing door lock is equipped with a secondary lower hook and a secondary door-opening device comprising a rotary rod, a secondary emergency unlocking device, a rotary board and a pull rope. The secondary lower hook in a cocurrent arrangement with a lower hook is fixed at the back of the lower hook in a horizontal door-opening direction. Meanwhile, the summit of the secondary lower hook is higher than the summit of the lower hook. One end of the rotary rod is connected with an upper hook and the other end thereof is connected with the elevator landing door via the pull rope, the rotary board and the secondary emergency unlocking device. The above mechanical equipments ensure that the operation of the manually-operated opening of the elevator door is in accordance with the safe operation standard. By utilizing the elevator landing door lock, a time buffer is provided for the operators who open the elevator door crudely. When elevator door is manually opened by the operator for the first time and then the door lock is unlocked for the second time, the position of the elevator car can be correctly determined by the operator. In other words, since the operator stands just before the seam of the opened door and faces the elevator shaft, he or she could see whether the elevator car stops just at the layer or not by observing through the door seam. Therefore, the accidents of falling in hoistways are avoided.

Description

The elevator door door lock

Affiliated technical field

The utility model relates to a kind of elevator door door lock, especially relates to a kind ofly can preventing the elevator operation personnel cause crashing into from layer door the elevator hoistways accident because of improper operation elevator door door lock effectively.

Background technology

Along with the fast development of elevator industry, elevator operating personnel casualty accident happens occasionally, and in these personnel casualty accidentses, it is one of modal elevator casualty accident that the elevator operating personnel crashes into hoistway from layer door.For this reason; relevant departments in all parts of the country draw lesson from it; strengthen management; as formulate corresponding elevator management system (the particularly management of layer door triangular key), stick safety instruction, the education of reinforcement elevator safety etc. at the layer door place of unblanking, these measures have reduced the generation of this class accident effectively, but because of various reasons; this class accident still idol has generation; trace it to its cause, except that elevator user violation operation, traditional layer every lock defencive function imperfection also is one of reason wherein.

Existing elevator door opening mode, use triangular key just can open arbitrary layer of door of elevator fully, one of purpose of opening elevator door if do not observe the position of car in the hoistway earlier, is then opened the danger that there is the hoistway that falls behind the door in layer in order to enter car or sedan-chair top fully.Simultaneously because the careless omission of triangular key management, also caused some layman to use triangular key to open to fall behind the elevator door accident of hoistway.Trace it to its cause, except the off one's guard and unprofessional external factor of operating personal thought, it also is the internal cause of accident potential that elevator door can simply directly be opened by triangular key fully.

The manual unlocking apparatus of known elevator door is to drive push rod (or other device) by triangular key to open the mechanical latch hook of layer door, then just can complete manually opened layer door by the crack between a door and its frame of opening.During personnel, the people need be by opening the situation that elevator door enters car or observes elevator hoistways in the maintenance or the sedan-chair of overcoming difficulties.Because elevator door is the safety curtain of isolating hoistway and people playground,, the danger of the hoistway that falls is just arranged during manually opened elevator door when lift car during not at this stop.

At present, a step of using the elevator door triangular key to open layer door does not also have standard, and elevator circle but has a common recognition, that is: the step that will follow with key manual unlocking layer door be " two see one slowly,, three action.Detailed process is as follows:

One, a hand is opened a layer door lock hook with layer door key, and the another hand is pushed layer door aside a seam, makes layer door unlikely closing under the effect of self-closing power.

Two, the layer every seam by opening, the position of observation lift car.

If the position of three cars (or sedan-chair top) is at this layer, both hands are pushed layer door (and gate) aside, enter car (or sedan-chair top).

But because of multiple reason, thin as indivedual elevator operation personal security consciousness, violation operation, link in the middle of saving is just pushed layer door open a bigger width when opening latch hook with layer door key, at this moment, if car (or sedan-chair top) is not at this layer, what elevator operation personnel faced will be an abyss, if think in elevator operation personnel's the subconsciousness that just (because be before that its car is parked in this layer, other people have reached other floor to car to car at this layer.Perhaps elevator display apparatus shows car at this layer, and in fact car not at this layer), add and wait more in a great rush at that time that accident just very likely takes place, this has a lot of accident examples is to demonstrate,prove.

Summary of the invention

In order to take precautions against the hoistway accident of falling with the contingent personnel of key operated elevator door, technical problem to be solved in the utility model provides a kind of elevator door door lock, change present elevator door and just can once directly open the mode of layer door by the triangular key operation fully, when using triangular key to open layer every lock, the action of opening the door for the first time can only be opened elevator door the width of 100-150mm (this width can effectively prevent personnel from falling hoistway), further open layer door fully and then must rotate the secondary energency-unlocking device that is located at layer reveal face once more or with pulling the moving opened layer of stay cord of face behind the door with triangular key.

The technical scheme that its technical matters that solves the utility model adopts is: by locking the secondary door lock opening device that increases by a cover mechanical interlocking fender guard and match at traditional layer every; when layer door closed; rise to the bait and the engagement of following hook; hook is fixed on down the back of hook along the level direction of opening the door under the secondary; arrange in the same way with following hook; and its apex height is higher than the apex height of hook down; one end of the bull stick of secondary door lock opening device is connected with rising to the bait, and the other end is connected by stay cord, flap, secondary energency-unlocking device and layer.

Compare with existing layer door unlocking apparatus, the beneficial effect of novel layer door unlocking apparatus is, can not once open layer door fully, layer door (and gate) is preceding opening fully, guarantee that by mechanical device the unlock staff must carry out a control step again, this control step has two kinds of methods, and the one, the secondary energency-unlocking device that rotates layer reveal face that be located at triangular key will be gone up latch hook and lift; The 2nd, with a hand put in layer behind the door face operate a stay cord, will go up latch hook once more and lift, thereby open layer door (and a gate).The purpose of this control step, be to provide a room and time of observing car position for the elevator operating personnel, before making it stand in the elevator door crack between a door and its frame of opening, and in the face of elevator hoistways, when carrying out unblanking the second time, stitch by an opened layer every and whether to observe lift car just at this layer, or stretching out one's hand layer subsequently behind the door during face pulling stay cord, if car is just at this layer, safety edge touching (layer door and the about 30mm in the gap of safety edge) by the back of the hand and gate, whether the sensation car helps its correct position of judging car at this layer, thereby prevents to crash into the generation of hoistway accident.

For the danger that prevents that personnel from may cause because of air rage, existing elevator door triangulation chain that the position is set is all higher, this highly makes unlock staff's health when carrying out unlock operation be in deformation state, be difficult to when unblanking, observe the position of car, and newly-designed secondary energency-unlocking device or stay cord are arranged on the suitable height, have solved this problem.Another advantageous effects of the stay cord that increases is to have reduced in the car or personnel's (when lift car ground or sedan-chair top are lower than stop ground) or the pit personnel danger (the stay cord lower end position is lower) when opening layer every lock is gone up on the sedan-chair top.

Novel layer every lock is that with the maximum difference of existing layer every lock the process of opening the door must become the mechanical device of setting up because of novel layer every lock by such step operation by former triangular key use and management system regulations unlock staff the unlock staff is had to by such step operation.

Novel layer every lock can prevent effectively that not only the unlock staff is in that to open the crude an dimpetuous behavior of layer Men Shiyin or other former thereby cause the accident of the hoistway that falls, and door lock structure is simple, productive costs increases few, does not change layer and sees outdoors, does not influence the functions of use of existing elevator.
