In the moving process of the steel wire rope 17, because the movement of the first driving cylinder 38 is a back-and-forth pulling action, the wound rotating wheel 52 is pulled to move up and down, the rotating plates 51 arranged at two ends of the rotating wheel 52 are pulled to move up and down, the rotating connecting plate 54 arranged at one end of the rotating plate 51 is pulled to move up and down, the piston telescopic rod 50 arranged at the upper end of the rotating connecting plate 54 is pulled to move up and down in the telescopic base 48, the space at the bottom of the telescopic base 48 is driven to become larger or smaller in the moving process, if the telescopic base 48 moves inwards, air at the bottom of the telescopic base 48 is pushed to enter the communicating pipeline 65, then the air enters the air injection bin 56 through the communicating pipeline 65, and then the air is sprayed outwards through the plurality of one-way air nozzles 57 arranged at the bottom of the air injection bin 56, so that the air can be sprayed to the rotating cylinder 15 and the contact point between the rotating wheel 52 and the steel wire rope 17, the temperature reduction and the removal of impurities at the position are carried out, and when the telescopic base 48 is pulled downwards through the steel wire rope 17, the air inlet 63 is pumped. In this relation, the upward movement of the piston rod 50 is to retract the wire 17 inward, and although there is a certain pressure, the piston rod 50 is pulled upward due to the second spring 55 provided at the bottom thereof.
If the steel wire rope 17 is suddenly broken, at the moment of the breakage, the rotating wheel 52 loses all pressure, at the moment, the piston telescopic rod 50 is quickly jacked up under the action of the second spring 55, so that the ejector rod 49 arranged at one end of the piston telescopic rod 50 is pushed to move upwards, the top of the ejector rod 49 is contacted with the bottom of the piston block 45 and jacks up the piston block, the air bin air outlet 43 is in an air ventilation state, and therefore air in the air bin 14 can enter the clamping bin air inlet 59 through the hose on the outer side of the air bin air outlet 43, the push plate 61 on one side of the clamping bin air inlet 59 is pushed to move outwards, the push rod 62 arranged on one side of the push plate 61 is pushed to move outwards, the clamping plate 53 arranged at one end of the push rod 62 is pushed to clamp the steel wire rope 17 under the mutual clamping force, and the oil extractor 16 is prevented from falling into the well. In this connection, the ram 49 does not lift the piston block 45 because the running wheel 52 is always under a certain pressure without breaking the cable 17, and this design only clamps the cable 17 on the side close to the elevator car 10 when it breaks.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
