Application of automatic control system of hoist in main shaft of Wutongzhuang Coal Mine

  • 摘要: 针对梧桐庄矿原提升机电控系统存在运载能力不足、安全可靠性不高、自动化控制程度较低等问题,提出了一种提升机自动控制系统改进方案,介绍了该方案中电动机变频调速系统、基于现场总线的通信系统和安全监控系统等的关键技术原理。应用结果表明,改进后的系统与原系统相比,电动机定子平均温度下降约10 ℃,转子平均温度下降约20 ℃,且定子绕组中的测温元件和水冷单元都有助于降低电动机运行故障率;运行速度可达10 m/s,单钩运行时间约为135 s,提升载荷达到设计要求的25 t;采用Profibus和多层次体系构架设计,各功能模块、通信接口、系统服务和系统监控等隶属不同层级,保障了系统的可靠性和扩展性。
    Abstract: In view of problems of low carrying capacity, low safe and reliable performance and low automation control degree existed in original electronic control system of hoist of Wutongzhuang Coal Mine, a reforming scheme of automatic control system of hoist was put forward, and key technical principles were introduced including frequency-conversion speed-regulation system of motor, communication system based on field bus and safety monitoring system. The application results show that average temperature of motor stator is about 10 ℃ lower than that of the original system, average temperature of rotor decreases by about 20 ℃, and temperature measuring element and water cooling unit in stator windings all contribute to reduction of failure rate of the motor; operating speed of the hoist is up to 10 m/s, single hook running time is about 135 s, and lifting load is 25 t which meets design requirements; Profibus and multi-level system architecture were adopted, functional modules, communication interfaces, system services and system monitoring belong to different levels to ensure reliability and scalability of the system.
