地铁“守门员”:休息时坐地铁也不忘问诊屏蔽门

2018-01-08 01:50:21   中国新闻网

每到年根儿,大伙儿都盼着回家过年,可对于地铁车站维修督导孙迪和他的同事来说,却要想着如何确保春运期间的工作,让更多乘客平安出行。守护地铁屏蔽门的他,堪称是地铁“守门员”。

任何异常逃不出他的眼睛耳朵

“车门即将关闭,请您抓紧时间上下车”。伴随着“嘀嘀嘀”的提示音,地铁里的屏蔽门即将关闭,一个在站台等候了多时的小伙子依旧没有上车,他专注地盯着屏蔽门,侧耳倾听着。“声音有些不对啊”,他自言自语着。他,就是京港地铁车站维修督导孙迪,和地铁里行色匆匆的乘客一样,期待着屏蔽门的每一次快速开启。但他又和大家不一样,每次开门后,他几乎从不会踏上车厢,而是会关注屏蔽门的动作和声音,细微的异常抖动、轻微的异响都逃不过他的眼睛和耳朵。因为维持地铁内屏蔽门的安全、顺畅运转就是他工作的职责之一(上图)。

孙迪,1994年出生的北京小伙子。2012年,从北京交通运输职业学院毕业后就加入了京港地铁,成为了一名车站维修技术员。

夜间断电后检修是家常便饭

孙迪告诉北京晨报记者,和许多地铁一线工作人员一样,他们也需要进行白夜交替地倒班。白天一般是4人一组,每人携带重5公斤的工具包,在10座车站进行日常巡视,检查屏蔽门的状态。“比如开关门动作是否顺畅,有无抖动、缓慢的情况,有无异响。”孙迪说,同时,这个4人小组负责的10座车站中,如有屏蔽门突发故障,当站工作人员也会联系他们及时检修。此外,他们还要负责屏蔽门系统的检查以及其他车站设备的维护。

到了夜间,孙迪和同事们则要根据检修计划,对屏蔽门及车站相关设备进行例行的月度检修、半年检修、年度检修等。爬上梯子检修门体和门机传动装置,在夜间断电后下到昏暗的轨行区曲着身子检修屏蔽门与地面的固定件都是“家常便饭”。

冬天最难挨 手经常冻得发红发疼

工作5年的孙迪已习惯了早晚轮班,但冬天仍是最难熬的时候。北京晨报记者了解到,屏蔽门部分门缝测量需要精准到不大于5毫米的距离,为不影响操作的精准度,孙迪和同事们一般不会戴太厚的手套。在零下6、7摄氏度的地面站,他们的手经常会冻得发红发疼。

即便是到了温度适宜的春秋季,孙迪和同事们又要担心另一个问题——北京的风沙,对于地面站而言,风沙侵入屏蔽门会影响屏蔽门的顺畅运行,时间长了还会造成机械设备的损坏。于是在风沙较大的日子里,孙迪的工具包里会多备一些棉布、润滑剂,来保障屏蔽门的润滑。

休息时坐地铁也不忘问诊屏蔽门

再过一个多月就将迎来春节,就在万千乘客盼着回家过年的时候,孙迪和他的同事们却惦记着今年春运期间的种种工作。“春运期间,大量拎包乘客乘坐地铁前往机场、火车站,为了确保乘客出行,地铁会根据客流情况实时加开列车,这也就意味着,屏蔽门的日均开启闭合次数将增多,对于我和同事们来说,工作也就更艰巨。”孙迪表示。

5年“守护”地铁屏蔽门的工作让孙迪有些职业性的“神经质”,就算是在休息时乘坐地铁出行,他也会下意识地看看屏蔽门的动作、听听有没有异响。“屏蔽门与行车紧密相关,牵一发而动全身,一道屏蔽门发生故障,可能会影响整列车的正常运行。”孙迪表示。
