  作者 邓智云 胡靖 郭军

  “朱工,库里23道有台内燃机车,检修时要对LKJ车载设备多加留心。”1月19日9时,接到检修任务的朱程华,提着工具包向着机车辅修库里走去……

  45岁的朱程华,是广铁集团广州电务段车载检修车间的一名高级技师。从业23年,他一直从事机车车载设备检修作业,练就了一双“火眼金睛”。今年春运期间,朱程华和工友们加密了机车车载设备的检修频次。爬机车、登车顶、钻地沟,从5米高的车顶到1.5米深的地沟,都是他们检修的“战场”。

  机车车载设备中的LKJ是机车运行监控装置,相当于列车运行的“黑匣子”,是保障列车运行安全的关键设备。列车运行时,LKJ能够凭借列车底部的传感器和接收设备,实时接收地面信号设备传输的信息,为火车司机提供列车与前方信号机的距离,以及机车通过车站、道岔、弯道等位置时的运行参数,记录着司机的操作情况。

  “这处螺栓应该是松了。”进入机车的机械间内,朱程华侧身弯腰,将手电筒光照向LKJ主机的安装座螺栓上,一束光线顺着螺母与安装座中间狭小的间隙穿过。“检查时如果不侧身仔细观察,只看防松标识是无法发现该问题的,会有视觉死角。”朱程华说。

  朱程华使用无纺布,仔细擦掉LKJ机身及安装座螺栓表面的粉尘和油污,确认LKJ外壳无破损、裂痕,内部元件正常,使用套筒扳手将安装座螺栓拧紧。“机车运行的时候会产生轻微震动,如果安装座螺栓松动,将会导致设备在运行中移位,那就影响大啰。”朱程华边操作边介绍道。车内机械间空间十分狭小,朱程华顶着头灯贴着机车仔细查看线缆的安装状态。

  “速度传感器10芯插头的接口似乎有点松动。”朱程华用手摸着插头自言自语。由于速度传感器直接关系到机车的运行速度,速度出现误差会造成校准车轮距离的不准确,将会影响列车的运行安全。只见他拨开线缆查看插头的状态,发现紧固插头的内六角螺丝出现滑牙,需要立即更换。

  朱程华半蹲着身子,举着新的速度传感器,把10芯插头对接车体圆孔插座,“咔嚓”一声拧紧插头,紧接着转动正反向的驱动方轴。随后,他快步跑到司机室,查看LKJ屏幕上显示的速度参数,“参数正常!”

  “注意防溜。”这时机车内的广播响起了播报,朱程华用防水胶绑扎插头,加装防松铁丝紧固,不到10分钟,速度传感器便完成了更换。面对车载设备检修时,朱程华“五感全开”,眼观、耳听、手摸,一套动作行Welcome back. It's good to see you. Click below to log in to the rewards program at your property.如流水,在他身上形成了肌肉记忆,严格执行作业标准,守护机车车载设备安全。

  检修库内寒风呼啸,但在机车机械间内的朱程华,却忙得满头大汗,手上检修的动作越来越快。一天下来,朱程华与工友们完成了7辆机车的车载设备检修。(完)
