Abstract
The invention discloses a double-locking elevator-hall door interlock, which can prevent human bodes from falling into elevator shafts when elevator-hall doors are open in both normal use and abnormaluse. Besides comprising the function of the prior elevator-hall door interlock to lock elevators in normal operation, the double-locking interlock for elevator-hall doors also has the function of opening the hall doors in a limited distance and automatically turning on shaft lamps when the elevator-hall doors are opened during power cut, failure and maintenance. The interlock can be applicable tovarious passenger and freight elevators in vertical operation.
Description
Technical field:
The present invention relates to a kind of can also can the power failure in normal operation is used, fault in maintenance and other improper uses, prevents that human body is strayed into into elevator hoistways, thereby falls the double-locking elevator-hall door interlock of casualty accident.
Background technology:
At present, no matter be the elevator of which kind of vertical lift, use neutralization to have a power failure in normal operation, fault, the user of service all might be taken place in maintenance and other improper uses step on into elevator hoistways because the situation in the hoistway do not seen clearly is missed in the short time when opening hoistway door, thus the generation casualty accident.
Summary of the invention:
Purpose of the present invention is exactly in order to address the above problem, and providing a kind of can during normal use also can maintain, have a power failure, in the improper use such as fault, prevent that human body mistake from entering elevator hoistways, thereby the hoistway door of safety performance that improves hoistway door greatly is chain.
No matter hoistway door is a midsplit type and folding, and the technical solution used in the present invention is on the original single locking function basis that has of hoistway door interlocking, sets up another kind of locking function.Be characterized in above single locking function landing interlock locking bar, setting up a L type locking bar, rear inside has a minor axis string to cross at landing interlock to move adapter plate, be fixed on the L type on the locking bar behind the long rabbet of top, in the screwed hole, back, other end, shaft coupling rear end external diameter is obviously greater than shaft coupling middle part external diameter, and, in groove, come off to prevent shaft coupling also greater than the elongated slot insied width.After shaft coupling front end string goes out on the L type locking bar outside, put two flat gaskets, a quilt of haulage cable is curved behind two flat gasket centres, clipped by screw means, other one of steel rope is then partly walked around reel and is partly walked around down reel downwards again and be clipped in interlock plate top with chuck, about both sides, interlock plate top have two to move towards bar, and the space that keeps the distance in the gangbar both sides clamps gangbar, do not allow its outer incline inwards.Move towards the porose hole of being crossed same distance on the adapter plate that links with the parallel string of screw, bar two, by secured in parallel in the about both sides of interlock plate.Interlock plate top is had a hole to go here and there the clamp that screw is fixed on the interlock adapter plate by one one to block.Do not allow it swing.Have only when the Room outdoors personnel rotate turning block on its base with triangular key when rising, the pull-up lifting arm, the drive clamp raises up, the interlock plate is threaded off, unclamp haulage cable, the outer butterfly spring of first line of a couplet rod rear end is flicked, locking bar ejects the top that seals in fixing lock dog and the neutral gear of hoistway lamp open plate below forward in the promotion, the tooth mouth tenesmus of last locking bar leading portion lower edge, be stuck in fixedly lock dog upper edge, the upper edge then jack-up hoistway lamp open plate again transmission open the LX---028 switch, it is bright that the hoistway lamp is put, this moment, personnel just can be from by the limited crack between a door and its frame of opening outdoors in the Room, see situation in the hoistway clearly by the illumination in the hoistway, make accurate judgement, in order to avoid be strayed into hoistway, thus the generation of the casualty accident that prevents to fall.
The beneficial effect of the invention is:
1. remove elevator gate interlock when normal the use and can pin Room door, in improper use, also can pin Room door in case human body fall's casualty accident takes place.
2. what the present invention adopted is that pure mechanical device is used as power without any power source, the both available common power of well lighting, and also available emergency source of electrical power, structure is extremely simple.
3. it is very convenient to make installation.Do not destroy the aesthetic in appearance of hoistway door, can not produce unexpected injury human body.

Specific embodiments:
Present invention is described below in conjunction with Fig. 1 to Figure 10
Double-locking elevator-hall door interlock of the present invention comprises: the sealed movable base plate 0 of substance, locking bar 3 on the dual sealed pin piece adapter plate 2, last locking bar locating rack 4, last locking bar shifting chute hole 5, butterfly spring 6, interlock reel 7 is gone up sealed linkage portion and is divided adapter plate 10, lifting arm 11, interlock clamp 14, interlock radius stay 15, interlock plate 16, haulage cable 9
When landing interlock is during normal use sealed, be fixed on the mobile sealed adapter plate 0 on the door-plate of the Room, along with Room door leaf moves near being fixed on, the dual sealed pin piece adapter plate 2 that Room door leaf is put the beams in place is fixed on top on the fixing lock dog 21 and hits bolt 32 and answer back to, back down the passive contract piece 33 on the mobile adapter plate 0, the latter is pushed out down the bayonet socket on the locking bar 1 left, makes down locking bar under the promotion of spring 30, up bullet, hook fixedly lock dog 21, whole descending sealed process finishes.
When elevator because of having a power failure, fault, during stagnation of movement, maintainer's desire enters elevator hoistways outdoors and sues and labours from the Room, during maintenance, as long as triangular key is aimed at the hole that is fixed on the superolateral triangular key base 12 of Room door to insert, making clockwise direction rotates, make the triangular key turning block 13 in the door of the Room make anticlockwise motion, up mention lifting arm 11, lifting arm 11 mention again the rear end by the degree of tightness appropriateness by the interlock clamp 14 that is bolted on interlock adapter plate 10 left sides, threaded off by the interlock plate 14 by being bolted to interlock adapter plate lower end of degree of tightness appropriateness in the lower end, unclamp haulage cable 9, locking bar 3 is ejected by butterfly spring 6 to the right, seal in the fixedly neutral gear between lock dog 21 upper ends, its front end is well lighting switch opens plate 7 rear ends jack-up up, thereby make on the well lighting switch opens plate 7 the semicircle extrados in the rear end on the plane back down LX---028 switch 36 and open well lighting, the lower edge contract mouth of last locking bar 3 its front end lower edges is then down made meshing shape, and to hook the upper end of fixing lock dog 21 sealed.What this moment, operating personal can be limited opens Room door, from crack between a door and its frame, sees situation in the brilliantly illuminated hoistway of a slice clearly, makes right judgement, in order to avoid be strayed into hoistway, tragedy takes place.
Seeing the situation of hoistway inboard clearly when operating personal after, when desiring to enter hoistway, only need lift locking bar 3 and make it and fixedly lock dog 21 disengagements, make it can open hoistway door and enter hoistway with hand.After this with the turning block 13 that hands down on the triangular key base 12 lifting arm 11 is moved down, with the pulling of turning right of handgrip trace 16 tops, haulage cable 9 just draws locking bar 3 repositions again.The clamp 14 that links this moment just can block interlock plate 16 downwards again in the compacting of butterfly spring 36, recovers to go up the sealed preceding state of lock down system again.
