Description

technical field [0001] The invention relates to an on-line detection device and method for the lay length of a steel wire rope, which is especially suitable for real-time detection of the change of the lay length of a steel wire rope when equipment such as a hoist or winch is hoisted or pulled, and belongs to the technical field of equipment detection and safety. Background technique [0002] The main load-bearing element of the mine hoist is the steel wire rope, which will bear various loads during the working process, such as tension, bending, contact stress and dynamic load. Studies have shown that as the well depth increases, the torsional stress increases. When the well depth exceeds 800-900 meters, torsion is the main cause of wire rope damage. The twisting of the wire rope causes the lay length to vary along the length of the wire rope. By measuring the lay length of the wire rope, you can know the size of the torsional stress in the wire rope. [0003] A method fo...
