摘　　要：传统履带牵引首绳更换装置液压提升系统通过利用平衡阀在液压回路中建立适当的反压力,用于实现负负载的平稳下降,但在轻载和时变负载的情况下会造成液压系统能耗大、效率低和发热严重等问题。为此,在传统液压提升系统中,通过采用图解法分析平衡阀先导比、设定压力等关键参数与系统能耗的关系,提出使用外部压力源流独立控制先导压力的方法控制平衡阀的开启,设计一种基于平衡阀先导压力独立控制的新型液压提升系统。利用液压系统仿真软件AMESim建立传统液压提升系统和新型液压提升系统的仿真模型,并对2种系统在首绳更换作业工况下进行仿真分析。仿真结果表明:新型液压提升系统具有明显的节能效果,相比传统液压提升系统,其节能效率可达78.24%。The counterbalance valve is used in traditional hydraulic lifting system of the crawler traction head rope replacement device to establish the appropriate back pressure in the hydraulic circuit,which is used to achieve the steady drop of negative load,but it can cause problems such as high energy consumption,low efficiency and serious heat generation in the case of light load and time-varying load.Therefore,in the traditional hydraulic lifting system,the relationship of key parameters such as counterbalance valve pilot ratio and setting pressure with system energy consumption was studied by using graphical method.A method of using the external pressure source to independently control the pilot pressure was proposed to control the opening of the counterbalance valve,and a new hydraulic lifting system was designed based on the independent control of the pilot pressure of the counterbalance valve.The hydraulic system simulation software AMESim was used to establish the simulation models of the traditional hydraulic lifting system and the new hydraulic lifting system respectively,and the two systems were simulated and analyzed in the head rope replacement working conditions.The simulation results indicate that:the new hydraulic lifting system has obvious energy-saving effect,compared with the traditional hydraulic lifting system,its energy-saving efficiency can reach 78.24%.
