根据国内现有矿井提升机特点,结合现代监测与诊断技术,设计开发了一种用于矿井摩擦式提升机制动装置的在线监测系统。介绍了系统构成、参数采集方案和故障诊断策略,并提出了利用制动减速度测量闸瓦摩擦系数的方法。试验表明,该系统性能良好,是提高提升机安全性、可靠性的一种行之有效的方法。 According to the existing mine hoist features, combined with modern monitoring and diagnosis techniques, an on-line monitoring system for the brake of mine friction hoist was designed and developed. The system configuration, parameter acquisition scheme and fault diagnosis strategy are introduced. And the method to measure the friction coefficient of brake shoe by using brake deceleration is put forward. Experiments show that the system has good performance and is an effective way to improve the safety and reliability of the hoist.
