摘　　要：介绍以电液执行器作为动力源的转辙机,并对电液执行器的结构、转辙机的工作原理进行分析。由于电液执行器集成度高且体积小,新型电液转辙机较传统电液转辙机体积更小;使用电液执行器作为电液执行系统的集成模块,在液压传动故障时只需整体进行更换即可,维修方便;电液执行器液压传动稳定,使用寿命长,免维护。因此,对比传统电液转辙机,使用新型电液转辙机可以有效提高道口工人的工作效率,降低道口运营维护成本,最大限度地保障列车的安全运行。This paper introduces a switch machine with electro-hydraulic actuator as power source,and analyzes the structure of the electro-hydraulic actuator and the working principle of the switch machine.Because of the high integration and small size of the electro-hydraulic actuator,the new electro-hydraulic switch machine is smaller than the traditional one;The electro-hydraulic actuator is used as the integrated module of the electro-hydraulic actuating system.When the hydraulic transmission fails,it only needs to be replaced as a whole,and the maintenance is convenient;the hydraulic transmission of electro-hydraulic actuator is stable with long service life and is free of maintenance.Therefore,compared with the traditional electrohydraulic switch machine,the new electro-hydraulic switch machine can effectively improve the working efficiency of the crossing workers,reduce the operation and maintenance cost of the crossing,and ensure the safety of the train operation to the greatest extent.
