Abstract
The utility model discloses a time relay elevator car door lock which is low in cost, is simple and easy to install, is reliable in motion, and has independent mechanisms and a wide application range. The time relay elevator car door lock comprises an electric control lock, a relay, a position detecting mechanism and a storage battery which are electrically connected; the electric control lock controls a car door to keep a locked or unlocked state; the position detecting mechanism detects whether the car door is positioned at the flat layer position, and when the car door is positioned at the non-flat layer position, the relay controls the electric control lock to enable the car door to keep the locked state; when the car door is positioned at the flat layer position for a period of time which is not longer than the set value of the relay, the relay controls the electric control lock to enable the car door to keep the locked state; and when the car door is positioned at the flat layer position for a period of time which is longer than the set value of the relay, the relay controls the electric control lock to enable the car door to keep the unlocked state. So the car door can be opened only at the layer door position, and when the car door is at the non-layer door position, the car door cannot be opened with external force, and the car door is more safe and reliable in the running process of a car.
Description
Technical field
The utility model relates to a kind of elevator cage door lock, specifically, relates to a kind of gate release that when elevator cage door is in level position, realizes, when elevator cage door is in non-level position, realizes the time relay elevator cage door lock of gate locking.
Background technology
The gate locking device of elevator is one and is mainly used in elevator at not gate zone position locking gate; The fender guard that can reliably open again in the door zone position; Stipulate according to standard GB 7588-2003 " elevator manufacturing and installation safety standard ": the horizontal throw at the edge, nearest doorway of elevator hoistways inside face and car sill, car door framework or sliding door should be greater than 0.15m, the above-mentioned spacing that provides:
A) rise to 0.20m, it highly is not more than 0.50m;
B) for the cargo lift that adopts vertically sliding door, this spacing rises to 0.20m in whole stroke;
C) if car be equipped with mechanical interlocking the door and can only layer door unblank the district in open; Except the said situation of 7.7.2.2; The locking of gate should be automatically depended in the operation of elevator; And gate locking must confirm that then above-mentioned spacing is unrestricted by the electric safety device that meets the 14.1.2 requirement.
From present elevator industry present situation, the large-scale commercial building height reach 150 meters or more than, the height of elevator hoistways also increases thereupon because elevator hoistways depends on the construction precision of building civil engineering side, and there is certain degree of difficulty in the control of the vertical missing of building.Corresponding counter-measure is also arranged now.But the expense that these measures took place is uncontrollable, and preciseness is not enough.
For satisfying of the horizontal throw requirement of above-mentioned GB to the edge, nearest doorway of elevator hoistways inside face and car sill, car door framework or sliding door; Should not depend on the construction precision of building civil engineering side; But should consider that exploitation is satisfied the elevator GB and required, installs gate mechanical lock simple and easy, reliable in action from elevator structure itself.
Because present elevator cage door all is to keep gate to close through door motor; Do not possess the mechanical lock hook device, when the lift car flat bed, elevator in house software control program is confirmed car flat bed state through each incoming signal; Output signal to door motor, gate is opened; During non-flat bed, keep gate to close by door motor.But because door motor has moment reversal protection function, (during >=150N) converse rotating force, door motor reverses so as manpower door motor is produced enough greatly; Or elevator is in faulty condition, and the door motor dead electricity makes gate open, and then can effectively prevent the unusual opening of gate that manpower causes if possess the gate of mechanical lock hook device.
Though the former existing reply technology of elevator cage door lock, former Technology Need is made amendment to the elevator original program, and the gate system mechanics is partly had specific (special) requirements, complicated circuit, and cost is higher.
