The invention discloses a railway signal machine which comprises a shell, a plurality of main indicator lamps are fixedly inserted into the left side of the shell, and a PLC is fixedly installed at the position, close to the left side, of the top of an inner cavity of the shell. An electric-hydraulic push rod is started to push a movable block to move forwards and drive a limiting rod to be separated from the right sides of a plurality of circular plates, then a second servo motor is started to drive a transmission rod to rotate and drive a threaded sleeve to move towards the side away from the inner cavity of the shell, and therefore a plurality of standby indicator lamps are moved to the outer side of the shell; the first servo motor is started to work to drive the rotating rod to rotate, and the rotating rod drives the shell to rotate by 180 degrees, so that the standby indicating lamp is used for replacing work, normal traffic operation is guaranteed, and the situation that traffic accidents are caused by indicating lamp faults is avoided.
本发明公开了一种铁路信号机,包括壳体,所述壳体的左侧插接固定有若干个主用指示灯,且所述壳体的内腔顶部靠近左侧处固定安装有PLC控制器,本发明在使用时,当主用指示灯出现故障时,首先,可通过远程控制PLC控制器,并启动电液推杆推动活动块向前移动,并带动限位杆从若干个圆板的右侧脱离,接着,启动第二伺服电机带动传动杆旋转,并带动螺纹套向远离壳体内腔中的一侧移动,从而将若干个备用指示灯移动到壳体的外侧,通过启动第一伺服电机工作可带动转杆旋转,并通过转杆带动壳体旋转一百八十度,从而让备用指示灯替代工作,保证正常的交通运行,避免发生指示灯故障而引发交通事故的情况。
