Abstract

The invention provides a nondestructive flaw detector for steel wire ropes, and solves the problem that quantitative detection of wire break and wear in steel wire ropes cannot be realized by the prior art. The nondestructive flaw detector for steel wire ropes comprises a steel wire rope walking positioning mechanism, a magnetic leakage flux detector, an optical detector, a photoelectric encoder, and an embedded signal processing system. The steel wire rope walking positioning mechanism is provided with a steel wire rope channel, the inner wall surface of which is fixed with the magnetic leakage flux detector, the optical detector and the photoelectric encoder. The embedded signal processing system is fixed on the steel wire rope walking positioning mechanism, and the magnetic leakage flux detector, the optical detector and the photoelectric encoder are connected to the embedded signal processing system. By combining a magnetic leakage flux technology and an optical determination technology to perform signal feature extraction and quantitative analysis on wire break, pitting corrosion, wear and other defects of steel wire ropes, the nondestructive flaw detector realizes online high speed and high accuracy detection of the steel wire ropes.

Description

Technical field [0001] The invention relates to the field of wire rope flaw detection equipment, in particular to a wire rope nondestructive flaw detector. Background technique [0002] Steel wire rope is the main load-bearing component in the project. It is widely used in coal, metallurgy, transportation, transportation, construction, tourism and other major industries and sectors of the national economy. Its safe use has attracted much attention. For a long time, people have adopted manual visual inspection and regular replacement of steel wire ropes to avoid accidents. However, the manual visual inspection method has poor reliability and low efficiency, and regular replacement causes huge waste. Electromagnetic testing was applied in the early twentieth century. At present, the electromagnetic non-destructive testing of wire ropes can be used to detect the loss of the metal cross-sectional area of ​​the wire rope. It can detect internal wire breakage and wear, corrosion, and w...
