摘要
有色金属矿山在深井开采过程中普遍面临高磨蚀性矿石运输带来的设备损伤难题。无轨设备作为井下无轨运输的核心装备,其传动系统在粉尘侵入、冲击载荷和高温环境的长期作用下,容易出现齿轮点蚀、轴承剥落、油液劣化与密封失效等问题,导致寿命周期明显缩短。传动系统的早期磨损失效不仅会增加维修成本,还严重影响设备出勤率和运输效率。为解决相关问题,研究提出了从材料表面工程、密封与油液清洁度控制、以及智能状态监测与预测性维护三方面的寿命延长路径,形成了“材料-管理-智能”协同的综合技术体系,结果表明,该体系可以显著降低部件磨损速率,延长大修周期,提升整体生命周期的经济性。
Nonferrous metal mines generally face the problem of equipment damage caused by the transportation of highly abrasive ores during deep well mining.As the core equipment of underground trackless transportation,the transmission system of trackless equipment is prone to problems such as gear pitting,bearing peeling,oil degradation,and seal failure under the long-term effects of dust intrusion,impact loads,and high temperature environments,resulting in a significant reduction in its service life.The early wear and failure of the transmission system not only increases maintenance costs,but also seriously affects equipment attendance and transportation efficiency.To solve related problems,a life extension path has been proposed from three aspects:material surface engineering,sealing and oil cleanliness control,and intelligent state monitoring and predictive maintenance.A comprehensive technical system of"material management intelligence"collaboration has been formed.The results show that this approach can significantly reduce component wear rates,extend overhaul cycles,and improve the overall economic efficiency of the life cycle.
