泄漏通信与立井井筒提升机信号闭锁功能开发

Development of Blocking Function of Leakage Communication and Shaft Hoist Signal

针对立井井筒作业安全系数要求较高的问题,开发了一种泄漏通信与提升机信号闭锁功能,用以实现在立井井筒检修过程中采用泄漏通信手持对讲机打点对提升机信号进行闭锁、解锁操作;详细介绍了通过提升机信号系统的改造和通过提升机电控系统的改造2种途径实现该闭锁功能的方案。实际应用表明,该功能实施后,立井井筒作业人员可直接参与提升机控制,不需要开车时即闭锁提升机信号,提高了立井井筒作业的安全性。

In view of problem of higher requirement for safety factor in shaft operation,a blocking function of leakage communication and shaft hoist signal was developed,which was used to realize blocking and unlocking operation for hoist signal by dotting of hand-held interphone of leakage communication in maintenance process of shaft.Implementing schemes through two ways namely reforms of hoist signal system and electrical and control system of hoist were introduced in details.The actual application shows that operation personnel of shaft can participate in hoist control directly and can block hoist signal when need not startup,which improves safety in shaft operation.
