Device and method for monitoring friction and corrosion fatigue damage to twisted type lifting steel wire rope of super deep vertical shaft

Abstract

The invention discloses a device for monitoring friction and corrosion fatigue damage to a twisted type lifting steel wire rope of a super deep vertical shaft. The device comprises a supporting system, a tension-tension fatigue system, a constant-temperature corrosion system, a dynamic loading system and a monitoring system, wherein the supporting system supplies supporting to the tension-tension fatigue system, the constant-temperature corrosion system, the dynamic loading system and the monitoring system; the fatigue steel wire rope to be monitored is provided with a fatigue load supplied by the tension-tension fatigue test system in the horizontal direction, a dynamic contact load supplied by the dynamic loading system in the vertical direction, and a constant-temperature corrosion environment supplied by the constant-temperature corrosion system respectively; the monitoring system monitors the fatigue load, the dynamic contact load and a change of friction force on the fatigue steel wire rope. The device can realize the friction and corrosion fatigue damage to steel wire ropes on adjacent twisted layers of a twisted type lifting machine of the super deep vertical shaft under different temperatures, corrosion solutions, different dynamic tensile loads and different dynamic contact load parameters and dynamically monitor the damage.

Description

technical field [0001] The invention belongs to the field of mining, in particular to a super-deep shaft winding hoisting wire rope friction corrosion fatigue damage monitoring. Background technique [0002] In recent years, with the rapid development of my country's 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. According to statistics, my country's coal mining is developing at a rate of 8-12m per year. With the increasing consumption of coal resources, the mining depth of my country's mines will inevitably reach 1000-2000m in the next 10 years. received the attention of many scholars. When the height of the multi-rope winding hoist is greater than 1500m, it is superior to the multi-rope friction hoist in terms of lifting capacity and limit lifting height. Therefore, multi-rope winding hoisting systems are often used for ultra-deep mine ...
