Design and Simulation Analysis of the Transmission Scheme for the Mine Double Speed Winch

Mine winches are widely used in coal mine production, but the traditional operation mode still exists and the transmission efficiency is low. In order to improve the transmission efficiency of mine winches, this paper designs a transmission scheme for the mine double speed winch. Briefly, the transmission scheme is introduced and the degree of freedom of the winch mechanism is discussed to guarantee the rationality of the movement. The kinematics mathematical model of the winch is established. Theoretical derivation and simulation analysis show that the winch mechanism has superior performance at a high or low speed. The combination of fast speed and slow speed can effectively improve the transmission efficiency of the mine winch, which provide a design thought. (paper)
