Abstract： Mine endless rope winch is widely used in coal mine production, but the transmission efficiency of traditional operation mode is low. In order to improve the transmission efficiency of mine winch, taking the JYB mine endless rope winch of Cilinshan Coal Mine as an example, a transmission scheme of mine endless rope frequency conversion double-speed winch was designed. Through theoretical analysis and dynamic analysis, the feasibility of the structure was verified. The electromagnetic radiation interference performance of the new type of winch is tested. The radiation noise of the transmission mechanism of the new frequency conversion double speed winch is mainly from the inverter and the motor. The radiation noise value is weak, and the electromagnetic radiation environment around the equipment is less affected, which can meet the actual use requirements of coal mine engineering.
