Rail transport conveyer is special transportation equipment that is widely used in the field of metallurgical industry. It is the key to ensure equipment operation efficiency on a production site. But the low lift system efficiency and poor reliability are difficult technical problems in the enterprise. In this case, rail transport conveyer uses the worm gear and screw nut lifting mechanism. The project carries on rail vehicle lifting system modeling and dynamic simulation study through Solid Edge ST5 and ADAMS, combined with simulation technology, virtual prototype design. Research purpose is in order to match the coefficient of friction between the screw and screw nut better, and to match different speed ratio for the drive gear pair and the lifting mechanism being in empty back to travel and work schedule. Another aim is to match the speed of the lifting speed and walking speed, and to reduce the error probability. Results show that the motor can get better speed matching relation with lifting mechanism through research, further optimizing the structure of lifting system parameters. Through the analysis and structure optimization, we can improve the reliability of rail transport vehicle lift system, and implement efficient fast for copper anode lifting and positioning precision. The ultimate goal is to achieve vertical hanging in electrolytic cell anode plate, and to make electrolytic operation to achieve the best state.
