Design And Manufacture Of High-Power And Strong-Strength Belt Conveyor

With the increasing of huge filling sea engineering and opening air mine as well as high productive and efficient mine. As one of the main material handling equipments,Long distance and huge freight volume become the belt conveyor's main developing trend. So it is the demand of the times developing to explore high-power and strong-strength belt conveyor. Its significance is crucial. The most important technology is dynamic analysis and monitor control. Based dynamic analysis, the high-power and strong-strength belt conveyor of Xinglongzhuang mine of Yanzhou mine group is designed and selected, and it is performed in this paper.Dynamic characteristic of belt conveyor is introduced. The variety of the dynamic load, the calculation of the transmission speed of the elasticity wave and the surge of the belt are analyzed. Then the calculation of the equivalent moment of inertia of the conveyor is analyzed and the simplified calculation model is founded. The most excellent acceleration controlling curve is concluded through comparing the loads in different controlling curve and their effects in the dynamic load severally.The high-power and strong-strength belt conveyor of Xinglong- zhuang mine is designed and selected: Driving device and electric controlling system are collocated logically surrounding dynamic analysis and monitor controlling technology; through static and dynamic calculating, driving power, belt strain, parking times, negative direction stopping moment etc are drawn. The electromotor, arrester, coupling and reducer that mostly suit to the belt conveyor are selected trough comparing all components' performance of driving device.optimum design optimum is carried out to some parts according to the actual condition, it not only makes the reliability improve but makes the disassembly and assembly more convenient. Then all other parts are selected.
