[Abstract]:Belt conveyor is the most important coal transportation equipment in coal mine. For coal mines which have been exploited for many years, the geological conditions become complex, and the original belt conveyor is often unable to adapt to the production conditions. In order to expand the application range of belt conveyor and improve its use efficiency, it is necessary to carry out adaptive technical transformation of belt conveyor. In this paper, the short distance rock transportation device and the forced turning device of belt conveyor are designed, and the short distance transportation and turning operation of retractable belt conveyor are successfully realized. Through PLC programming of the centralized control system of the conveyor, the high adaptability of the system to the production conditions is guaranteed, which is the coal of DP mine. Rock transportation provides equipment support. 1) the short distance rock transportation device is modified on the basis of DSJ80 retractable belt conveyor. By redesigning the head part and tensioning device, the reasonable driving device is selected. The problem of rock transportation in short distance roadway is solved well. 2) combined with the parameters of the general structure of the roller group at the bend of the belt conveyor, a general forced turning device of belt conveyor with vertical roller is designed. When turning at a small angle, the parameters of the general structure are simulated by adding the vertical roller to realize the non-forced turning, and when the turning angle is large, the forced turning is realized by adding the vertical roll and the pressing roller. 3) by self-programming, A set of centralized control system of working face conveyor suitable for the production mode of the mine is developed, which reduces the maintenance cost and improves the fault treatment and emergency ability of the system. At present, the achievements of adaptive technical transformation of mining belt conveyor have been successfully applied in DP Mine, running well, realizing the design requirements, and providing the necessary equipment guarantee for production.
