某选煤厂产品车间矸石运输系统采用绞车牵引翻矸车至矸石山顶端在大绳的牵引下完成自动翻矸的过程。绞车翻矸系统自投用以来,出现了电控系统故障率高、绞车小绳使用寿命短、安全隐患多等问题,该厂技术人员经过多方面调查研究,对矸石山翻矸系统进行了一系列改造,取得了很好的效果。改造完成后,翻车系统运行更加安全稳定,电控系统故障次数大大减少;绞车小绳的使用寿命由原来的2至3天延长至6至8天,节约了大量人力资源和材料费用,每年仅小绳和卡子就节约材料费10万元以上;另外改造后生产的安全性也得到明显改善。
A coal preparation plant product workshop gangue transport system using winch traction turning the gangue car to the top of the gangue in the rope under the traction to complete the automatic turning waste process. Winch turning waste system since put into use, there has been a high failure rate of electronic control system, short life of the winch rope, many hidden dangers and other issues, the plant technical staff after many investigations and studies on the waste dump waste rock gang system Series transformation, and achieved good results. After the completion of the transformation, the rollover system runs more safely and steadily, and the number of faults of the electronic control system is greatly reduced. The service life of the winch rope is prolonged from the original 2-3 days to 6-8 days, which saves a lot of manpower and material costs, Small rope and clamp on the material cost savings of 100,000 yuan or more; the other after the transformation of production safety has also been significantly improved.
