【摘要】：带式输送机是散状类物料输送的重要设备,已经广泛应用于煤炭、矿山、港口、电力、冶金、化工和生产流水线等诸多领域。近年来,工程应用中长距离、大输送量的带式输送机的需求变得越来越多,对于带式输送机长距、重载的工程需求愈发凸显。而传统的单点驱动带式输送机已不能满足这类的工业需求,带式输送机的多点驱动方式应运而生。本文研究了多点驱动带式输送机的整机设计,探讨加大传动力的有效方法,从以下三个方面阐释多点驱动的设计方法。输送带是带式输送机最重要的部件之一,并且一般是暴露在特别恶劣的环境中,持续不断的高效工作,这就对输送带的质量、材料和尺寸要求特别高。在原有研究成果的基础之上,本文探讨了弹性变形小、粘弹性低、强度高的新材料胶带在生产输送机皮带领域的应用。驱动装置的设定、选取、布置形式,是多点驱动带式输送机控制系统主要的研究内容。在长距离或重载状况下,带式输送机驱动装置的动力分布对于机构效率,以及输送带工况的影响非常大。驱动装置的合理布置,可以有效的提高带式输送机工作效率并降低能耗。控制系统是多点驱动的带式输送机的“大脑”,是带式输送机各个机构协同工作的调度重心。本文对带式输送机的控制系统进行了研究。根据多点驱动带式输送机的驱动特性,采用可编程逻辑控制器(PLC)对输送机各个机构的工作状态进行实时监控,完成对信息的采集、上报等,同时与矿区局域网互联,可实现远程自动化控制。本文利用某煤矿原煤的堆积程度,确定堆积角,因为不同的矿区和工作环境会影响到带式输送机的角度取值,进而会影响到整体的工作效率和损耗情况。计算了圆周驱动力、最大张力、最小张力和设备有效的制动力,根据不同工作环境和工况,计算了其力学取值,选择合适的输送带和电动机等部件。对多点驱动带式输送机的整机设计过程及方法提供了系统的参考,并对多点控制系统的后续研究工作提出了建议,本文提出(PLC)控制系统加网络控制的协同控制是多点驱动带式输送机的设计核心和发展方向。
[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.
