Apparatus and method for detecting interlayer friction of steel wire rope of winding-type hoist

摘要

Disclosed are an apparatus and method for detecting an interlayer friction of a steel wire rope of a winding-type hoist. The apparatus comprises a support, a loading steel wire rope positioning system, a connector-free steel wire rope positioning system, a brake 5 system, a power loading system and a state monitoring system, the loading steel wire rope positioning system, the connector-free steel wire rope positioning system, the brake system, the power loading system and the state monitoring system being disposed on the support. A friction wear experiment between a loading steel wire rope and a connector-free steel wire rope on a rotational hub can be implemented, and the apparatus is configured to reveal a 10 steel wire rope friction wear fracture mechanism and evaluate the wear damage evolution of each steel wire rope and the fatigue life of each steel wire rope. An interlayer friction situation of a steel wire rope on a winding-type hoist roller can be simulated, a stable steel wire rope contact load can be continuously applied by adopting a fixed pulley positioning apparatus and an electric pull rod loading mode controlled by computer software, a friction 15 force, a temperature field and a friction coefficient between steel wire ropes and an expanding law of internal cracks of the steel wire ropes can be monitored in real time, and an effective experimental device is provided for revealing a steel wire rope friction wear fracture mechanism, evaluating the friction damage evolution of each steel wire rope and evaluating the fatigue life of each steel wire rope.
