摘要: 掘进机是煤矿巷道机械化掘进中最重要的设备,目前仍由司机手动操作。由于掘进环境恶劣,工作条件差,粉尘、水雾等影响司机的视野,造成掘进巷道断面成形质量差、劳动强度大。针对上述问题,文章介绍了一种掘进机智能型自动成形恒功率截割控制系统,详细介绍了智能型自动成形恒功率截割控制系统中掘进巷道断面自动成形控制和截割头恒功率自动牵引调速控制的设计与实现,并介绍了该系统在EBZ200型掘进机上的应用情况。实际应用表明,该系统实现了远程在线监视、诊断与控制功能,使操作人员远离工作面迎头,减少了人员伤害事故,对实现安全、高效自动化巷道掘进具有一定的现实意义。Abstract: Tunneling machine is the most important device in mechanical tunneling of coal mine roadway,but it is operated by driver with hands.Because of bad tunneling environment,poor working condition and dust and water fog influencing visual field of driver,bad forming quality of tunneling roadway section and big labor intensity are caused.Aiming at the above problems,the paper introduced an intelligent control system with automatic forming and constant power cutting of tunneling machine,introduced design and implementation of automatic forming control of tunneling roadway section and automatic traction speed-regulation control with constant power of cutting head of the system in details,and gave the application of the system on EBZ200 tunneling machine.The actual application showed that the system realizes functions of on-line remote monitoring,diagnosis and control,which makes operator away from working face and reduces person injury accidents,and has certain practical significance for automatic roadway tunneling with safety and high efficiency.
