Abstract

In order to solve the problems of winches in fully mechanized coal mining face used to do the roadway supports withdrawal work, such as the difficult operation, the tedious positioning, the inefficiency, the frequent pull-off and rope breakage and so on. A new dual-speed multi-purpose withdrawal winch with variable frequency speed control and self-supporting positioning system is proposed in this paper. Firstly, The shape and performance boundary parameters of the new winch are obtained by analyzing and investigating the existing winches and the requirements of the new. Secondly, the transmission system is designed including the calculation of drum, the development of variable frequency motor with low speed and high torque and the design and arrangement of reducer. Then the overall structure of the new dual-speed multi-purpose winch is designed by combining the researches mentioned above and the development of the optional support device. Finally, from the application effect of the new winch, the design scheme of overall structure is reasonable, reliable and fully meets the actual demands.
