When elevator actuating device normally runs, described stop tight device and manual locking device all inoperative, roller still freely rotates, when coupler unclamps or disconnect, coupler can touch travel switch, travel switch signal transmission is to controller, controller controls tight device startup of stopping, and locking roller brake facing, stops the rotation of roller, owing to being provided with former and later two tight devices of stopping, therefore, gripping power is larger, and locking effect is better, fall arrest when achieving elevator stall, improves the safety in operation of device.
Compared with prior art, the present invention has the following advantages and beneficial effect:
1, the present invention is without the need to arranging responsible locking mechanism, and it is reliable and stable that equipment self can realize lifting locking, realizes safety first;
2, by travel switch can be sensitive detection coupler whether have fault, and in time information can be passed to controller, the controller tight device that controls at once to stop is locked, and therefore, lock sensitive, speed of response is fast.
3, be also provided with manual locking device, can manual locking be carried out, improve equipment safety supportability.
4, compact conformation, saves greatly and takes up room, simultaneously lower to processing request, reduces manufacturing cost.
