Steel wire rope lateral vibration signal measuring device, method and lateral vibration monitoring method

Abstract

The invention relates to a steel wire rope transverse vibration signal measurement device and method and a transverse vibration monitoring method. The measurement method comprises the steps that induction light curtains emitted by two groups of light curtain type laser displacement sensors are mutually perpendicular, and the planes on which the two groups of light curtains are positioned are parallel and vertically arranged in a spacing way; and a steel wire rope perpendicularly penetrates through the two groups of light curtains simultaneously so that the displacement signals of the steel wire rope along x and y directions in transverse vibration are obtained. The measurement device comprises two groups of light curtain type laser displacement sensors and a support. The induction light curtains emitted by the two groups of sensors are mutually perpendicular, and the planes on which the two groups of light curtains are positioned are parallel and vertically arranged in the spacing way. The monitoring method comprises the steps that the vibration displacement signals are measured by adopting the steel wire rope transverse vibration displacement signal measurement method; and the vibration displacement signals are processed so that vibration amplitude and vibration frequency are obtained and are compared with the preset values, and then crisis prevention is performed through judgment. According to the device and the method, accurate measurement of steel wire rope comprehensive transverse vibration can be realized, and prediction of dangerous vibration can also be realized.

Description

technical field [0001] The invention belongs to the technical field of testing of mine hoisting systems, and in particular relates to a steel wire rope transverse vibration signal measuring device and method and a transverse vibration monitoring method. technical background [0002] Ultra-deep mines generally refer to mines with an operating depth greater than 1,000 meters. At present, most of the mines in our country are shallow wells with a depth of 500-800 meters. However, the mining powerhouses of the world have reached depths of 2,500 to 4,000 meters. In my country, coal resources buried at a depth of 1000-2000 meters account for about 53% of the total reserves. For this reason, it is of great significance to study the hoisting equipment of ultra-deep mines and solve the key technologies of hoists in ultra-deep mines to ensure the security of national resources and expand the strategy of deep resources. [0003] The ultra-deep mine hoisting system is a large and comp...
