The fixing device is connected to the speed governor of the elevator, so that the steel wire rope stripping device for the speed governor of the elevator inspection of the present invention is integrally fixed on the speed governor of the elevator, so as to avoid shaking of the steel rope due to its own insufficient gravity during the stripping process.

The working principle of the present invention is as follows: we take off the end of the steel wire rope 7 to be stripped, wind it on the first sheave 2, and wind the replacement rope 71 with a length greater than or equal to the steel wire rope 7 on the second sheave 3 in advance . Since the first transmission wheel 21 and the second transmission wheel 31 are connected by transmission belt 4, so we only need to control the rotation of the first transmission wheel 21 or the second transmission wheel 31 through the motor 41, then the first sheave 2, the second rope The wheel 3, the first transmission wheel 21, and the second transmission wheel 31 will all rotate synchronously, and the steel wire rope 7 and the replacement rope 71 are connected by a rope connection assembly. A rotation loop is formed between the first sheave 2 , the second sheave 3 , the first transmission wheel 21 , the second transmission wheel 31 , the steel wire rope 7 , and the replacement rope 71 . Turn on the motor 41 to drive the first sheave 2 to rotate, and make the wire rope 7 gradually wind around the first sheave 2, and the replacement rope 71 is gradually untied from the second sheave 3. When the wire rope 7 is completely wound around the first sheave On the wheel 2, close the motor 41 to complete the stripping of the wire rope 7. Now open the rope connection assembly, take off the wire rope 7, the replacement rope 71 then replaces the position of the wire rope 7, the whole process depends on the equipment, the wire rope 7 is not easy to shake, and avoids the friction and collision between the wire rope 7 and elevator parts such as the hoistway, the wire rope 7 and the operator The contact time is shorter than that of simple manual rope drawing, which reduces the risk of scratching the operator's limbs.

Motor 41 can adopt two-way rotating motor, and during forward rotation, steel wire rope 7 peels off, and replacement rope 71 replaces, and during reverse rotation, steel wire rope 7 replaces, and replacement rope 71 peels off; Motor 41 also can adopt unidirectional rotation motor.

Replacement rope 71 can adopt new steel wire rope, then plays the effect of replacing old steel wire rope, if just want to strip off original old steel wire rope, then replacement rope 71 adopts surface smooth or material is soft or lighter cable, cable etc., even if these ropes and Collision of parts such as the hoistway will not damage other parts of the elevator due to the advantages of light texture, soft material or smooth surface.

In order to facilitate the connection and disassembly of the steel wire rope 7 and the replacement rope 71, we have provided a detachably connected first sleeve 5, a first connector 51, a second connector 6 and a second sleeve 61, as shown in Figure 4 and Figure 4. Shown in 5, these parts connect together then steel wire rope 7 and replacement rope 71 are connected together, dismantle any one of them, then steel wire rope 7 can be separated with replacement rope 71.
