摘要
液压支架作为煤矿综采机械的关键设备,因其耗材多、自重大、一次性投资费用昂贵,如何合理预测液压支架的寿命显得尤为重要。在对液压支架经济性寿命、可靠性寿命、安全性寿命和技术性寿命进行分析研究的基础上,给出了液压支架寿命评价体系的评判树,为液压支架的安检、维护以及寿命评价提供了参考。
The hydraulic support is the key equipment of fully mechanized mining machinery in the coal mine.Because of its lots of material consumption,the heavy weight and the high cost of one-time investment,it is very important to reasonably predict the life of the hydraulic support.The hydraulic support′s economic life,safety life,reliability life and technical life were analyzed and studied,on this basis the evaluation tree of hydraulic support life evaluation system was established,which can provide reference for the safety inspection and maintenance of hydraulic support.
