The invention discloses a twisted-type hoister steel wire rope interlayer friction detection device and method. The twisted-type hoister steel wire rope interlayer friction detection device comprises a support, and a loading steel wire rope positioning system, a connector-free steel wire rope positioning system, a brake system, a power loading system and a state monitoring system which are arranged on the support; a test for the friction abrasion between a loading steel wire rope and a connector-free steel wire rope on a rotating hub can be realized, and the device can be used for disclosing a steel wire rope friction abrasion fracture mechanism and evaluating the abrasion damage evolution of each steel wire rope and the fatigue service life of each steel wire ropes. A steel rope interlayer friction state on a twisted-type hoister roller can be simulated, a stable steel wire rope contact load can be continuously applied by adopting a fixed pulley positioning device and an electric pull rod loading way controlled by computer software, friction force, a temperature field and a friction coefficient among the steel wire ropes and an expanding law of internal cracks of the steel wire rope can be monitored in real time, and an effective experimental device can be provided for disclosing the steel wire rope friction abrasion fracture mechanism, evaluating the friction damage evolution of each steel wire rope and evaluating the fatigue service life of each steel wire rope.

Description

technical field [0001] The invention relates to an interlayer friction detection device and method for a winding hoist wire rope, especially suitable for the experiment of simulating the use environment and working conditions of the wire rope on the winding hoist drum in the mine hoisting process, and for detecting the winding hoist drum The friction condition between the layers of the upper wire rope. Background technique [0002] With the rapid development of the national economy, my country's demand for mineral resources has increased significantly, prompting the continuous expansion of the mining of underground mineral resources in my country. With the increase of mining depth, deep well mining and transportation issues have also attracted much attention. The average mining depth of mines in my country is about 500m. With the consumption of shallow mineral resources, the mining depth will inevitably reach 1000-2000m in the future. At present, single-rope winding hoists...
