Optimisation and Improvement of Flat Tail Rope Protection Device in Sub-Riser Hoisting System
Zhengzhuang coal mine deputy shaft hoisting system lifting height 752.8m,the maximum lifting speed of 11 m/s,installed flat tail rope protection device,but the original design of the tail rope protection device on the tail rope side of the wear and tear of the heavier,affecting the safety of coal mine production.The causes of hoist tail rope damage are analysed,and the tail rope protection device is optimized and improved.The results of practical application show that the optimised and improved flat tail rope protection device has a significant effect on the wear and tear protection of the tail rope,effectively reduces the wear of the tail rope side,and the tail rope electrical protection system is comprehensive and reliable,which effectively guarantees the safe and reliable operation of the hoisting machine system,and the safety and economic benefits are significant.
