The Electrical Control Design And Research Of Meishan Mining Hoisting Machine Extension Transformation

The hoisting machine is the key point in a mine, since its safe and stable operation contributes to the normal production of a mine. The main function of the hoisting machine includes hoisting of ore, staffs and materials. Hoisting machine is regarded as the airplane in all ore machines. Only up or down. Once there is an accident, the airplane crash, the accident is doomed to be the worst. Therefore, the safe operation is the most important. It is important to maintain hoisting machine, improve its speed governing performance and fault handling man-machine interface as to reach the main goal of its enhancement.The extension transformation project of Meishan mineral company's chippy hoist is one of the key process of the second stage extension project and this project also makes progress of the mechanic and electronic parts of the chippy hoist. Besides the present equipment, converter, electromotor and electronic control part all need more design works. The usual PLC, Siemens S7 can improve the mechanical and electrical network. Adoption of wire network control technology design can reduce field wiring and electrical accident?Introduction of host computer can improve the logs and display of chippy hoist's operation, making man-machine interface possible, and help the monitoring of chippy hoist and its failure recovery. Selecting the gate control equipment of ABB can provide insurance.According to the modeling, installation, adjustment and operation of this hoisting machine, its electronic control system has the characters, including suitable modeling, the main circuit of the unit parameters matching good and economical operation. The superior performance of speed control of electric control part, comfortable riding and full-range of security are observed. It can meet the needs of safe production and the expectation of its improvements.
