[Abstract]:Belt conveyor is an important equipment for bulk material transportation, which has been widely used in many fields such as coal, mine, port, power, metallurgy, chemical industry and production line. In recent years, the demand of belt conveyor with long distance and large quantity of conveyer becomes more and more, and the demand for long distance and heavy load of belt conveyor becomes more and more prominent. But the traditional single point drive belt conveyor can not meet this kind of industrial demand, and the multi-point driving mode of belt conveyor emerges as the times require. In this paper, the design of multi-point drive belt conveyor is studied, the effective method of increasing transmission force is discussed, and the design method of multi-point drive is explained from the following three aspects. Conveyor belt is one of the most important parts of belt conveyor, and is generally exposed to a particularly harsh environment, continuous and efficient work, which requires high quality, material and size of conveyor belt. On the basis of the original research results, this paper discusses the application of new material tape with small elastic deformation, low viscoelasticity and high strength in the field of belt production of conveyors. The setting, selection and layout of driving device are the main research contents of multi-point drive belt conveyor control system. Under the condition of long distance or heavy load, the power distribution of belt conveyor drive device has a great influence on the efficiency of the mechanism and the working conditions of the conveyor belt. The reasonable arrangement of driving device can effectively improve the work efficiency of belt conveyor and reduce energy consumption. The control system is the "brain" of the multi-point driven belt conveyor, which is the center of dispatch for the coordinated work of the various organizations of the belt conveyor. The control system of belt conveyor is studied in this paper. According to the driving characteristics of multi-point driving belt conveyor, the PLC (PLC) is used to monitor the working state of each mechanism of the conveyer in real time, to collect and report the information, and to connect with the local area network in the mining area. Remote automatic control can be realized. This paper makes use of the accumulation degree of raw coal in a certain coal mine to determine the stacking angle because different mining areas and working environment will affect the angle value of belt conveyor and then affect the overall working efficiency and loss. The circular driving force, the maximum tension, the minimum tension and the effective braking force of the equipment are calculated. According to the different working conditions and working conditions, the mechanical values are calculated, and the appropriate conveyor belt and motor are selected. This paper provides a systematic reference for the design process and method of the multi-point drive belt conveyor, and puts forward some suggestions for the follow-up research work of the multi-point control system. In this paper, the cooperative control of (PLC) control system and network control is proposed as the design core and development direction of multi-point drive belt conveyor.
