Description

technical field [0001] The invention relates to the technical field of steel wire rope damage detection, in particular to a steel wire rope holographic detection system. Background technique [0002] As a key component of equipment such as hoisting, hoisting, lifting, traction, and bearing, wire ropes are widely used in various fields of the national economy (such as mine hoists, oil drilling and workover rigs, cableways, cable cars, cranes, bridge pull slings, elevators, traction cables, fixed cables, load cables, etc.). For a long time, due to the lack of scientific and effective comprehensive testing methods, the safe use of wire ropes has always been a difficult issue in safety management. The steel wire rope is a helical steel wire bundle that twists steel wires that meet the requirements in mechanical properties and geometric dimensions according to certain rules. The steel wire rope is first twisted into strands by multi-layer steel wires, and then twisted into a he...

Problems solved by technology

[0007] The third type: the nondestructive flaw detection of the steel wire rope is carried out solely through the nondestructive flaw detection equipment using the electromagnetic principle, which can detect various damages such as broken wires, wear, corrosion, and fatigue of the steel wire rope; The number of broken wires, surface corrosion, and different types of external damage, etc., require visual identification of defects, but there is nothing we can do

Although the artificial visual method and the caliper diameter measurement method have technical defects such as serious missed detection, low efficiency, and high labor intensity, there are also reasonable factors.

For example: the number of broken wires on the surface of steel wire ropes 6d and 30d can be clearly determined by visual inspection (this is very important, because the steel wire rope testing standards in various countries have provisions on the quantitative judgment of broken wires on the surface); manual caliper measurement of diameter is indeed true. An effective method to detect the diameter shrinkage value of steel wire rope; therefore, the single use of electromagnetic non-destructive testing equipment to detect the damage of steel wire rope still cannot meet the technical requirements of comprehensive and comprehensive damage detection

[0008] At present, some users use electromagnetic non-destructive testing equipment to detect steel wire ropes. They think that the detection method of artificial visual inspection and caliper measurement is less efficient and the technology is very backward; the research found that there is no combination of visual inspection and diameter change in the current existing technology. It is a comprehensive, efficient and accurate non-destructive testing equipment that organically combines the three detection functions of detection and non-destructive testing (in addition, it also lacks the marking function of the damage position)

Therefore, the detection accuracy in the traditional technology is not high, the degree of refinement is not enough, the detection efficiency is low, and it cannot meet the regulations of the steel wire rope testing standards of various countries and the requirements of the testing site, which seriously affects the quality of the steel wire rope testing, and is prone to false detection and missed detection. Thus, it is impossible to provide a more secure wire rope detection guarantee
