矿井提升机稳车集中控制系统

Centralized control system for winch of mine hoister

针对矿井提升机稳车常采用的继电控制方式存在的保护简单、操作人员劳动强度大等问题,介绍了一种以PLC为控制核心、以电动机综合保护器为主要保护器件、以触摸屏为人机界面的新型稳车集中控制系统。该系统实现了某煤矿新主井4台16t稳车及2台10t稳车的单台运行、多台同步运行以及多台稳车运行时的单台停止、多台同步停止功能,稳车电动机的多种保护功能以及稳车参数的实时显示功能,提高了稳车安全运行的可靠性,减轻了操作人员的劳动强度。

For problems of relay control mode used in winch of mine hoister such as simple protection, larger workload and so on, the paper introduced a centralized control system for winch of mine hoister which takes PLC as control core, takes integrated protector of motor as main protection device, and takes touch screen as human-machine interface. The system realizes functions of independent operation, synchronous operation, independent stop and synchronous stop of four winches of 16 t and two winches of 10 t operators, multi-protection of winch motor, and real-time display of winch parameters, which improves reliability of safe operation of winch and reduces labor intensity of operators.
