中国高铁首列检修列车投入使用

2017-08-16 08:53:02   中国青年网

□ 本报记者 戚加绚 于江

经过一个多月的调试运行,8月7日,中国高铁首列检修列(JJC型接触网检修作业车)在青荣城际线路正式投入使用,这意味着铁路供电检修科技装备保障迈入全新时代。

据了解,作为高铁运行动力供给源头,目前接触网检修的主要方式依然是十几个人推着一台梯车,在线路上爬上爬下,不仅与高铁的高大上格格不入,而且很多部位检修不到。随着高铁路网越来越密,这种效率低、死角多的检修方式亟待改变。

8月8日,记者登上了JJC型接触网检修作业车这个庞然大物,见证了它的神奇。据济南铁路局青岛供电段检修车间安全技术员刘铁介绍,这辆检修列由10节作业车和2节牵引车组成,车顶安装了175米长的贯通升降作业平台,整列全长220米,最高运行速度达120km/h,是目前全国装备最先进、科技含量最高的接触网检修作业车。

“以前上线作业上蹿下跳,一身泥一身汗,大家都说我们像蜘蛛侠,现在路局给我们配备了这么一辆移动的设备,我们这群蜘蛛侠也是有窝的蜘蛛侠了。”刘铁边说边带着记者登上了检修列,从车头的司机驾驶室一路前行,路过了工具间、会议室、厨房、餐厅、宿舍、最后来到了监控室。据刘铁介绍,检修列完全实现了材料加工、工具存储、食宿、现场指挥等功能一体化,作业人员生活条件大大改善。刘铁说:“我们在车上检修时遇到需要材料缺失,现场就能加工。而且通过监控大屏以及遍布车身的摄像头和传感器,使车内的指挥协调和安全保障更加从容。还有,检修列上为我们检修工配备了宾馆式软卧车厢,浴室、卧室一应俱全,每个卧室还装有壁挂式单体空调,冬暖夏凉。”

凌晨1:45分,检修列迎来了它正式上岗的第一个天窗点。首次亮相,它就要对青荣城际铁路前一天因为狂风暴雨造成断电的区间进行检修。记者看到,检修列车车顶作业平台就像一条百米跑道,平坦、宽敞、明亮。刘铁告诉记者,这个车最大的亮点就是这个作业平台,“以前人工车梯作业12个人一台车,作业区只满足2个人作业,司机、防护员等非检修人员约占工作组人数的70%,但现在检修列可以同时容纳30人作业,就像今天,上来3个工作组,全部都是检修工,大大提高了作业效率。”刘铁表示。

正说着,刘铁突然在一个线圈前停了下来,随后从包里拿出一个类似发卡的卡子捣鼓了起来,看到记者一脸茫然,刘铁说:“正常的话,这个卡子应该是卡在线里边的,这个一看就脱槽了。以前从发现到处理得二十分钟,现在有检修列一个人一分钟内就能解决。”

刘铁还告诉记者,检修列配有51处视频、语音监控系统,能够车上、车下联控,实现精确检修,可做到全覆盖、无死角、零遗落。“这个车就相当于我们的一个‘作战指挥部’,每天可根据供电4C检测监测系统提供的大数据,对设备检修点进行精准定位。”刘铁说。

凌晨3:20分,检修作业顺利结束,青岛供电段青岛检修车间副主任高佑东告诉记者:“检修列非常实用,它对铁路来说是非常可靠的作业平台,但是对检修工人来说更像是一个家。”据悉,目前,全国第一批14列检修列已在各铁路局配备到位,中国高铁接触网检修已迈入全新时代。
