[Abstract]:The deep well hoist test-bed studied in this paper provides theoretical and technical support for ultra-deep well hoist. The ultra-deep well hoist project is proposed to cater to the development of national strategic resources and deep resources, and to replace the single-rope winding mine hoist and multi-rope friction mine hoist with a single lifting depth of less than 1000 meters. Based on the national 973 project, "Research on crisis Prevention and safe Operation of Ultra-deep Mine hoisting system under unstable working conditions" (project number: 2014CB049404), this paper studies the unsteady working conditions of deep well hoist test-bed, including speed planning of hoist test-bed and tension balance control of two wire ropes. First of all, this paper fully analyzes the characteristics, performance and shortcomings of the existing mine hoist at home and abroad, and designs a double rope wound deep well hoist test bench. In this paper, the non-steady working condition of the double rope winding deep well hoist test bench is studied, the double rope winding deep well hoist test bed is built, and the stress analysis of the key components of the test bed is carried out, and the hydraulic components in the hydraulic circuit system and the sensors used in the test are selected. Secondly, aiming at the speed control of the hoisting system of the deep well hoist test-bed, the dynamic model of the hoisting system of the hoist test-bed is established in this paper, and the dynamic model is simulated and verified, and the dynamic model of the floating crane system is established in this paper. According to the organization structure of hoist test-bed, the simulation model of hoist test-bed is established in AMESim software, and the simulation verification is carried out. Then, the mechanism of wire rope tension difference in double rope winding deep well hoist test bench is analyzed, and the control strategy of wire rope tension leveling is planned on this basis. Under the planned running speed scheme of the six-stage speed hoist test-bed, the tension leveling control strategy of the wire rope is simulated and verified in the simulation model of the hoist test-bed. The simulation results verify the effectiveness of the PID controller and the backstepping controller in adjusting the tension recovery balance of the wire rope. Finally, the control system of the test-bed is designed, assembled and debugged, and the experimental verification of the tension leveling control strategy of the wire rope is carried out on the test-bed, which is carried out under two different speed schemes of the hoist test-bed in order to verify the effectiveness of the control strategy more accurately.
