Description
Technical field
The utility model relates to the door lock of elevator structure, refers in particular to a kind of twice of being used for door lock of elevator and opens falling proof device.
Background technology
At present, all kinds elevator is in the installation, maintenance process, and the staff of face need use triangular key to open Room door primary door latch and open Room door outdoors.At this moment, through regular meeting because the staff does not observe and knows to take advantage of a situation in the elevator stop place and enter and crash into hoistway and cause casualty accident to take place.The major cause of this safety misadventure is because the staff is opening the Room behind the door, assumes as a matter of course and thinks that car also is parked in this layer, enters into rashly and causes.Existing Room door primary door latch structure as shown in Figure 1, comprise the door lock seat 10 and the lock hook assembly 20 that catch on mutually, re-packing of lock hook assembly 20 bottoms and triangular key lock interlock 40 cooperates, when the staff uses triangular key when rotation, re-pack and 40 stir lock hook assembly and lift, break away from door lock seat 10, Room door is opened, also be provided with spacing reset attachment 30 on the lock hook assembly 20, lock hook assembly 20 other ends are provided with a life saving rope 24, also can draw life saving rope to open hoistway door from hoistway.As seen, just can fully door be opened as long as lock hook assembly 20 breaks away from the back with door lock seat 10 among the figure, whether some directly do not see car clearly at this layer in advance by custom with regard to entering.Causing of these safety misadventures is relevant with common people's custom, and the main cause that also becomes this class accident generation is directly opened in access, the Room.
The utility model content
The utility model is will solve above technical matters and provide twice of a kind of door lock of elevator to open falling proof device.
In order to reach the utility model purpose, this door lock of elevator that the utility model provides is opened falling proof device twice, comprise door lock seat and lock hook assembly, lock hook assembly comprises cross bar and one bonded assembly fork, fork and cooperate with re-packing of triangular key lock interlock, lock hook assembly one end cooperates with the door lock seat, the lock hook assembly other end is connected with life saving rope, lock hook assembly is provided with spacing reset attachment, it is characterized in that: described lock hook assembly cooperates end elongation with the door lock seat, the end is provided with second grab that cooperates with the door lock seat.After door lock was opened certain distance, the door lock seat cooperated with second grab, made door can not continue to open, and was beneficial to the position that unlocking person sees that car stops, and avoided it directly to enter in the car well.
The door lock seat is an end bending grab upwards, and cooresponding with it cross bar is provided with groove.
Second grab is outstanding downwards crozier.When cross bar upwards lifted, crozier can also hook the door lock seat after Room door is opened.
The cross bar middle part of lock hook assembly is fixed by hinge, and fork is downward perpendicular to cross bar, and fork is located between the hinge and door lock seat abutting end of cross bar.
Spacing reset attachment comprises a permanent seat, is provided with retracing spring and the caging bolt that acts on cross bar and permanent seat on the hinge both sides of cross bar, and wherein retracing spring is located at lock hook assembly and door lock seat abutting end one side.Swing position by spacing reset attachment adjustment doors lock set.
Described corresponding fork one side in the top that re-packs with the interlock of triangular key lock is provided with draw-in groove.After the fork bottom sticks into draw-in groove, re-pack and can not rotate again, guaranteed that the cross bar anglec of rotation is in suitable scope.
The utility model beneficial effect is:
1, the staff divides secondary opening Room door, causes the pause of Room door opening process therebetween, makes the staff have enough time to judge situation in the hoistway; And because the also useful action that pulls life saving rope of staff, make the process of the unlatching Room door that links up cause interruption, make the staff can go to judge situation in the hoistway consciously.Avoided the staff directly behind the door, the generation of the hoistway falling accident of by mistake entering into the key operated Room.
2, the position of life saving rope is provided with and also can considers apart from door limit, the Room at a distance, cause staff's operation of must leaning to one side to stretch out one's hand, thereby change staff's custom in the past: open the Room in the face of Room door and directly lift the work habit of riding into hoistway behind the door, safety misadventure is reduced greatly.
3, spur the life saving rope This move behind the door owing to stretch into the Room, can change the custom of staff the judgement of car position with hand.The staff pushed Room door aside a crack and observed for about 5,6 millimeters opening the Room in front of the door in the past.Because hoistway is often more black, is not easy to observe clear.
The utility model patent has successfully solved this difficult problem.If lift car is parked near this layer doorway or the doorway, car components can be run in positions such as staff's hand or the back of the hand in pulling life saving rope process, as: safety edge, gate, toeguard etc.If lift car is not parked near this layer doorway, pull and can not meet other any parts in the life saving rope process, the staff can judge car position not nearby.The tactilely-perceptible car position that long-term operation like this can make the staff form to utilize hand, i.e. situation in the hoistway.
The staff in the past seam of Room door observe can not accurately judge the situation of hoistway in, lean to one side to detect observe to judge it is more satisfactory and safe method with hand.
4, the utility model is changed not quite former technology, does not need additive incrementation equipment or power, and elevator power down mode, normal operating condition are all unaffected.And simple in structure, make easy for installationly, need not carry out the safety component type test separately.
