摘　　要：为了解决北京地铁屏蔽门电磁锁出现的机械故障问题,保障乘客的安全出行,针对北京地铁天通苑北站屏蔽门电磁锁出现的电磁锁打不开的现象,采用故障数据采集和分析,做出巴雷特累计频率曲线,根据曲线找出故障主要原因,循序渐进地做了两次技术改进;并对北京地铁1号线、房山线、8号线奥林匹克公园站、6号线电磁锁出现的机械故障做了技术改进。彻底解决了天通苑北站电磁锁锁舌晃动问题;解决了1号线电磁锁、房山线电磁锁、8号线奥林匹克公园站和6号线电磁锁出现的问题,使这些站台的屏蔽门电磁锁动作恢复如初。通过对北京地铁各线屏蔽门电磁锁出现的机械故障进行改进,能够使电磁锁恢复到正常工作状态,为国内其它城市地铁屏蔽门出现的电磁锁机械故障提供了借鉴。To solve the mechanical failure and problems of electromagnetic lock of Beijing subway screen door,and ensure the safe travel of passengers,of the electromagnetic lock of the screen door in Tiantongyuan North Station of Beijing Metro that can't be opened,the Barrett cumulative frequency curve is made by collecting and analyzing the fault data,and the main cause of the fault is found out according to the curve,and two technical improvements are made step by step.The mechanical failures of electromagnetic locks in Beijing Metro Line 1,Fangshan Line,Olympic Park Station and Line 6 are improved.The problem of electromagnetic lock pin shaking in Tiantongyuan North Station are completely solved.The problems of electromagnetic locks on Line 1,Fangshan Line,Olympic Park Station and Line 6 are solved,and the electromagnetic locks of screen doors on these platforms are restored as before.By improving the mechanical failure of electromagnetic locks of screen doors in Beijing subway lines,the electromagnetic locks can be restored to normal working conditions,which provides reference for the mechanical failure of electromagnetic lock in subway screen doors in other cities in China.
