Elevator driving rope sheave wear detection device and use method thereof

The invention belongs to the technical field of elevator maintenance, and discloses an elevator driving rope sheave wear detection device and a use method thereof.The elevator driving rope sheave wear detection device comprises a mounting plate, fixing assemblies are fixedly mounted on the left side and the right side of the bottom end of the mounting plate correspondingly, and fixing guide rails are fixedly mounted on the left side and the right side of the top end of the mounting plate correspondingly; and movable plates are arranged on the inner side surfaces of the two fixed guide rails. The recording assembly is arranged and matched with rotation of the driving rope wheel, namely, the characteristic that the surface of the driving rope wheel is abraded and is irregular is utilized, jumping of the contact head is achieved through the rotation action of the driving rope wheel, up-down jumping is converted into left-right movement through the action of the recording assembly, and recording paper moving rela
