Title:
STEEL WIRE ROPE INTERLAYER FRICTION DETECTION APPARATUS AND METHOD FOR WINDING-TYPE HOIST
Document Type and Number:
WIPO Patent Application WO/2016/141760
Kind Code:
A1
Abstract:
A steel wire rope interlayer friction detection apparatus and method for a winding-type hoist. The apparatus 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 provided on the support. By means of a fixed pulley positioning apparatus and a loading manner of an electric pull rod (19) controlled by a computer, a stable steel wire rope contact load can be continuously applied, and a friction force, a temperature field and a friction coefficient between steel wire ropes and an expanding law of internal cracks inside the steel wire ropes are monitored in real time, such that an interlayer friction situation of the steel wire ropes on a roller of a winding-type hoist can be simulated, a frictional wear experiment between a loading steel wire rope (12) and a connector-free steel wire rope (27) on a rotary hub (01) is implemented, a steel wire rope frictional wear fracture mechanism is revealed, and the friction damage evolution of the steel wire ropes and the fatigue life of the steel wire ropes are evaluated.
