Embodiment Construction

[0037] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0038] Such as Figure 1-6 As shown, a winding hoist wire rope interlayer friction detection device includes a bracket, a loading wire rope positioning system arranged on the bracket, a jointless wire rope positioning system, a braking system, a dynamic loading system, and a state monitoring system;

[0039] The support includes a base 17 and four columns 14 fixed on the base 17. The four columns 14 form a rectangle, and a crossbeam 25 is arranged on the top between the two vertical columns perpendicular to the axial direction of the drive shaft 28, parallel to the drive shaft. A fixed pulley support beam 11 is arranged in the middle between the two transverse columns in the axis direction of the shaft 28 .

[0040] The loading wire rope positioning system includes a fixed pulley support on the fixed pulley support beam 11, two fixed pulleys 13 symmetrical...

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.

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 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 (single-d...
