矿用带式输送机作为煤炭采掘工作过程中极为重要的输送设备，是煤炭企业正常生产作业的重要保障。控制系统作为矿用带式输送机重要组成部分，其控制技术的先进性直接关系着带式输送机的工作效率，必须引起高度重视。当前服役的矿用带式输送机多采用的是恒转速控制，运行过程存在皮带转速与运煤量不匹配问题，启动和运转时存在明显的抖动情况，制约了矿用带式输送机效率的进一步提升。为了解决上述矿用带式输送机存在的问题，以某煤矿在用矿用带式输送机为研究对象，开展自动控制系统的设计与应用研究，引入矿用带式输送机速度自动控制功能，对提高矿用带式输送机控制系统的可靠性、保证矿用带式输送机节能高效运行具有重要意义。基于此，本篇文章对 PLC 技术在带式输送机控制系统中的应用进行研究，以供参考。“,”As a very important conveying equipment in the process of coal mining, the mine belt conveyor is an important guarantee for the normal production and operation of coal enterprises. As an important part of the belt conveyor, the control system has a direct relationship with the work efficiency of the belt conveyor because of its advanced control technology, which must be attached great importance to. At present, the belt conveyor in service mostly adopts constant speed control. There is a mismatch between the belt speed and the coal transport volume in the operation process, and there is obvious shaking during the start-up and operation, which restricts the further improvement of the efficiency of the belt conveyor. In order to solve the problems of mine belt conveyor, in a coal mine in mine belt conveyor as the research object, the research on the design and application of automatic control system, the introduction of mine belt conveyor speed automatic control functions, to improve the reliability of the control system of mine belt conveyor, ensure efficient reducing energy for mine belt conveyor operation is of great significance. Based on this, this paper studies the application of PLC technology in the belt conveyor control system for reference.
