Description

Technical Field

[0001] This utility model relates to the field of wire rope testing technology, and in particular to a non-destructive testing instrument for wire ropes. Background Technology

[0002] Steel wire ropes are widely used as critical load-bearing components in numerous fields such as industrial production, construction, and transportation. Their safety performance directly affects the smooth operation of production activities and the safety of personnel and equipment. Therefore, non-destructive testing of steel wire ropes is essential, and the performance of the non-destructive testing instrument for steel wire ropes determines the accuracy and reliability of the test results.

[0003] Currently, performance testing of wire rope nondestructive testing (NDT) instruments faces numerous challenges. On one hand, the fabrication of wire rope samples is complex. Artificially creating broken wire defects is not only cumbersome but also difficult to precisely control the fracture dimensions, significantly reducing the accuracy of test results. Furthermore, creating internal broken wires is extremely difficult, making it challenging to effectively test the performance of wire rope internal defect detection. On the other hand, while steel bar samples can test the quantitative accuracy of LMA (Local Metal Loss) to some extent, their function is relatively limited, failing to evaluate other key indicators such as LF (Local Defect) detection sensitivity.

[0004] In practical applications, the lack of a comprehensive, efficient, and accurate method and tool for testing the overall performance of wire rope non-destructive testing instruments makes it difficult to fully verify their performance before they are put into use. This not only increases safety hazards during the use of wire ropes but may also cause unnecessary economic losses due to inaccurate testing, such as prematurely replacing wire ropes in good condition or failing to detect potential defects in time, leading to serious accidents.

[0029] The utility model is used as follows: It features a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, the steel bar sample 10 is placed in the placement groove 4. The steel bar sample 10 consists of a hollow tube 101, a hollow tube 102, and several steel bars 103. Stability is ensured during placement. Depending on the testing requirements, steel bars for verifying different performance indicators can be inserted into the steel bar sample 10, such as steel bars for verifying the resolution of continuous wire breakage signals, steel bars for verifying LF detection sensitivity, and steel bars for verifying LMA quantitative accuracy. Simultaneously, the detector probe 1 is fixed inside the card slot seat 29 using locking screws 210, completing the instrument installation preparation. During testing, the steel strips in the steel strip group sample 10 are replaced with test steel strips. Then, the clamping mechanism 3 is activated, and the piston rod of the cylinder 36 in the clamping mechanism 3 extends, driving the connecting plate 35 to move downward.

This, in turn, drives the connecting arm 26, the card seat 29, and the detector probe 1 to move. The detector probe 1 reciprocates on the steel strip sample 10 to magnetize it. Calibration is performed at the location without a break. After calibration, the machine is turned on for testing. The waveform is observed to see if there are two clearly separated signals, thus verifying the resolution of the continuous broken wire signal. When performing the LF detection sensitivity test, a break (the length after the break is 1) is machined.Steel bars of 5mm, 3mm, 6mm, 12mm, 25mm, 50mm (or as specified in the contract) are inserted into the steel bar sample 10 to replace the original steel bars. The detector probe 1 is then moved back and forth on the steel bar sample 10 via the displacement adjustment mechanism 2 for magnetization and calibration. After calibration, the instrument is powered on for testing to confirm the reliable detection of the waveform signal, thus verifying the LF detection sensitivity. For the LMA quantitative accuracy test, 10 steel bars used to verify the LMA quantitative accuracy are inserted into the steel bar sample 10 to replace the original steel bars. The displacement adjustment mechanism 2 is used to magnetize and calibrate the steel bar sample 10 via the detector probe 1. After calibration, the instrument is powered on for testing. One test steel bar is removed each time, and the LMA value of the detection waveform is read and compared with the standard value (the ratio of the steel bar to the entire sample group) to verify the LMA quantitative accuracy.
