Development and Experiment Research on Multi-function Wire Rope for Manned Rescue Lifting Equipment

Starting from the introduction of the method of manned rescue lifting for deep hole with large diameter, a multi-function requirement was proposed for loading and communication transmission to develop a special wire rope for ZMK5200QJY40 rescue and lifting vehicle, and a built-in four-strand 4V × 39S non-rotating wire rope structure was established with the coal mines safety requirements. Through the combination of numerical calculation and experimental research, the specific parameters of the wire rope were calculated, the wire and the central cable material, the workshop production process were optimized, and a multi-function wire rope was trial-produced. Based on the failure tensile test, the wedge-shaped ring combination was preferred as the connection method between the wire rope and the lifting cabin, after a series of fatigue and insulation tests, actual working condition simulation tests, etc., a kind of wire rope with functions of manned lifting and communication has been successfully developed, the structure was reliable enough to ensure the safety of the manned rescue process, and it has a reference significance for the series of multi-functional wire ropes development.
