提升机钢丝绳在线监测系统应用探讨

Discussion on the application of hoist wire rope online monitoring system

矿用提升机钢丝绳的超载、张力不平衡、张力差超限以及配重失衡等事故隐患时有发生,很难及时发现,引发滑绳、跳绳甚至断绳、坠罐等重大事故的发生。通过矿用提升机钢丝绳张紧力监测系统的研究,实现对提升机钢丝绳的张力数据的在线监测,监控提升机的运行和载重状态,对矿井提升机的安全及稳定运行有重要意义。矿井提升机钢丝绳张力监测系统主要由信号采集发射装置、信号接收器、压力传感器、接收箱、矿用隔爆型电池组、罐道轮取电装置及上位机软件组成。实践表明,该系统可对钢丝绳张力变化进行实时动态监测,提高矿井提升机的效率及可靠性、安全性。

Mine hoist wire rope overload,tension imbalance,tension difference exceeding the limit and counterweight imbalance and other accident potential problems occur from time to time,which is difficult to find in time and triggers major accidents such as rope slipping,rope skipping and even rope breaking and tank falling.Through the research of mining hoist wire rope tension monitoring system,it is important to realize the online monitoring of hoist wire rope tension data and monitor the operation and load status of hoist,which is important for the safety and stable operation of mine hoist.The mine hoist wire rope tension monitoring system is mainly composed of signal collecting and transmitting device,signal receiver,pressure sensor,receiving box,mining explosion-proof battery pack,tank road wheel power extraction device and upper computer software.Practice showed that the system can monitor the change of wire rope tension in real time and improve the efficiency,reliability and safety of the mine hoist.
