Steel wire rope online monitoring system and method

Abstract

The invention provides a multi-axial steel wire rope online monitoring system and method. The system mainly comprises: a data acquisition device used for acquiring leakage magnetic field and magneticflux change data generated for internal damage of the magnetized steel wire rope, wherein an excitation unit capable of instantaneously and axially magnetizing the steel wire rope deeply is arranged in the data acquisition device; a stroke metering device which is used for positioning the internal damage of the steel wire rope and acquiring damage position information; and a detection host which is used for receiving the leakage magnetic field and magnetic flux change data, converting the data and generating internal damage data of the steel wire rope in cooperation with the damage position information. Internal and external damage of the steel wire rope can be found in time, damage conditions such as abrasion, corrosion and internal wire breakage of the steel wire rope are accurately detected, major steel wire rope safety accidents are effectively avoided, and life and property safety is guaranteed.

Description

technical field [0001] The present invention relates to a non-destructive flaw detection system, in particular to an on-line monitoring system and method for a steel wire rope. Background technique [0002] Steel wire rope is a flexible load-bearing component commonly used in modern industry. It is widely used in coal, transportation, construction, tourism and many other industries. Method, solid-state acoustic measurement method, acoustic detection method, ray detection method and optical detection method, etc. [0003] The defect of the electromagnetic detection method is that if the wire rope contains wear and broken wires at the same time, it is impossible to distinguish which is the broken wire and which is the wear. [0004] The cost of solid-state acoustic measurement is high, and it is only suitable for laboratory research, because there are too many external interference factors, and it cannot be applied in the field. [0005] Acoustic detection method is one-side...

AI Technical Summary

Problems solved by technology

[0003] The defect of the electromagnetic detection method is that if the wire rope contains wear and broken wires at the same time, it is impossible to distinguish which is the broken wire and which is the wear

[0004] The cost of solid-state sound measurement is high, and it is only suitable for laboratory research, because there are too many external interference factors, it cannot be applied in the field

[0005] Acoustic detection method is one-sided in measurement, and it is also used in laboratory research. Because there are too many external interference factors on site, the accuracy of detection is too large, so it cannot be applied to the field.

[0006] The ray detection method has high detection cost and long cycle, and cannot detect planar defects in the direction perpendicular to the ray, and the ray is harmful to the human body, and the detection thickness is limited by the penetration ability of the ray, so it is not suitable for on-site use

[0007] The equipment cost of the optical detection method is high, and the steel wire rope will be covered with oil stains on site, and the oil stain will affect the judgment of the broken wire and wear of the steel wire rope by the optical detection method, and will also affect the detection accuracy, so this method is generally not used in field measurement
