【Abstract】 This paper introduces the operating mode of belt conveyor which is operated in the V sytle transporting lane way of coal mine. A new-sytle drive equipment hydraulic coupling and brake are also introduced. This equipment can meet needs of the special situation which has not only dynamoelectric operating mode of upward transporting, but also electric operaing mode of downward transporting. In this paper methods of detecting the operating mode of electric machinery and controlling hydraulic coupling and brake with PLC are demonstrated. The results of subaerial debugging show that the design is rational and has good performance.更多还原
