摘要
基于ZYJ7电液转辙机油泵组故障抢险需求,研究了一种便携式ZYJ7电液转辙机应急手扳装置,分析了应急手扳装置设计原理及结构,以及在南宁轨道交通线路中的试验情况.
To meet the demand of emergency rescue after failure of the oil pump group of ZYJ-7 electro-hydraulic switch machine,a portable emergency hand-operated switching device is proposed.Furthermore,the design principle and structure of the device are analyzed.In the end,the results of testing the device in Nanning rail transit lines are described in detail.
