Abstract: The exposed steel wire rope of the landing multi rope friction hoist runs under the conditions of low temperature, wet and cold, rain and snow in winter, which has the problem of surface icing. The ice on the steel wire rope is easy to reduce the friction coefficient of the hoisting system, which will cause the creep and slip of the steel wire rope, and may cause the hoisting accidents such as sliding rope and stall in serious cases. Therefore, the author puts forward a design idea of the wire rope deicing and drying device suitable for the landing multi rope friction hoist, which uses compressed air as the working medium and is used by the annular air knife after filtering and heating. The annular air knife releases high-pressure, high-speed and high-temperature airflow to continuously impact and melt the ice on the surface of the steel wire rope, so as to achieve the purpose of deicing and drying.
