Abstract

The invention discloses a wire rope flaw detection instrument based on magnetic flux leakage detection and optical detection. Data and test reports can be exported after the test is completed; accurate damage detection of wire ropes of different diameters can be achieved. The invention is a portable wire rope flaw detector, which can be carried by hand; the wire rope is excited by a permanent magnet, the signal is easier to capture, and the detection result for the small diameter wire rope is more accurate.

Description

technical field [0001] The invention relates to the field of nondestructive testing of steel wire ropes, in particular to a steel wire rope flaw detection instrument based on magnetic flux leakage detection and optical detection. Background technique [0002] The steel wire rope has the characteristics of light weight, high strength, good bending performance, stable and reliable operation, good elasticity, etc. It is widely used in elevator ropeways, mineral mining, port hoisting, industrial production and other fields. Due to the wide application of wire ropes, the damage detection of wire ropes is particularly important. [0003] At present, the non-destructive testing methods of wire ropes include current method, X-ray method, solid-state sound measurement method, magnetic method, etc. Among them, the magnetic method is suitable for the detection of wire ropes in different working environments due to its low cost, simple principle and easy operation. There are many wire ...
