1.前言 DLM型道口电动栏木机主要用于铁路与公路的平交道口上,在列车接近和通过道口时,阻挡公路上的行人和车辆通过。铁路运输部从1997年起引进第一套道口电动栏木机和道口信号机,经使用后认为其控制复杂,较难维修。根据其工作原理,对控制系统进行了改造,使其趋于合理化,系统简单,提高了可靠性和稳定性,并确认在本厂铁路系统内推广。至今,铁运部已有9个道口使用此系统,经济效益显著。
1. Introduction DLM type crossing electric fence machine is mainly used for the railroad and highway intersection, the train approached and through the crossing, blocking the passage of pedestrians and vehicles through. Since 1997, the Ministry of Railways has introduced the first set of crossing electric fence machines and crossing signal machines, which, after being used, considered the control complex and difficult to repair. According to its working principle, the control system has been transformed to make it rationalized, the system is simple, the reliability and stability are improved, and the promotion in our railway system is confirmed. So far, the Ministry of Railways has nine crossings using this system, significant economic benefits.
