Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire rope flaw detectors, in particular to a crane wire rope damage detection device. Background Art
[0002] A crane is a multi-action lifting machine used for vertically lifting and horizontally transporting heavy objects within a certain range. It is also known as an overhead crane, overhead crane, or crane. The safety of crane lifting depends primarily on the quality of the wire rope. Therefore, regular inspection of crane wire ropes is necessary to prevent accidents caused by broken wires or strands.
[0003] When inspecting wire ropes, a wire rope flaw detector is usually used. The principle of a wire rope flaw detector is to collect wire rope damage information through electronic detection technology and magnetic field radiation theory, analyze and process data, and form a test report to achieve quantification and visualization of defect detection. The specific contents are as follows: Collecting damage information: Using electronic detection technology and magnetic field radiation theory, by monitoring the stray magnetic field and the changes in the vector detection array, real-time and high-speed automatic collection of wire rope breakage, fatigue, rust, wear and other damage information. Analyzing and processing data: Combining multi-data fusion technology, such as wavelet algorithm and neural network, to analyze and process the collected big data. Generating test reports: Generating test reports such as the degree of damage at the damaged part of the wire rope, accurate location of the damage point, and electromagnetic waveform curve, to achieve quantification and visualization of wire rope defect detection.
[0004] Currently, wire rope flaw detectors on the market are equipped with rollers at the port to guide the wire rope as it passes through the flaw detector. However, in actual use, the rollers are squeezed by the swinging wire rope, which can easily cause the wire rope to shift from the rollers and derail. Furthermore, conductive impurities may adhere to the surface of the wire rope during use, which can easily affect the test results if not removed. Therefore, a crane wire rope damage detection device is provided to address the above issues. Utility Model Content
