赵国文:三十年如一日守护列车“心脏”

2017-08-03 20:05:53   

工作中的赵国文。

长城网8月1日讯(记者 胥文燕 通讯员 冯世新王坤)“首席技师的称号,老赵可真是当之无愧哦,这么多年苦心钻研总算没白费!”荣誉榜面前,人们无不翘起大拇指,啧啧称赞。 铁路车辆制动系统就好比汽车刹车装置,素有“车辆心脏”之称的制动阀是制动系统核心,性能好坏决定列车能否停得住、停得稳、停得安全。在石家庄车辆段,今年59岁的赵国文,专心钻研铁路货车制动阀检修已有30余年。 学历不高的赵国文从小就有一个要当铁路工人的梦想,曾经做梦都想亲自“驾驶”火车。1975年,他终于实现了自己的梦想,虽然没能“驾驶”火车,却当了一名车辆段的检修工人。自此,他与铁路结下了“不解之缘”。 “小小制动阀,140余个零部件、许许多多像毛细血管一样的通路构成,最细的孔径只有0.2毫米。就算是阀体清洁度、平整度有头发丝粗细的误差,也会影响制动阀的气密性,进而影响列车制动效果,甚至造成极其严重的安全事故。”赵国文参加工作后,在货车车辆“大夫”岗位8年历练,“有心”的老赵不仅熟悉了制动机的构造,还掌握了制动机在车辆运行过程中的作用原理、常见故障和处理方法,密密麻麻的管路在他的脑海里“脉络”清晰,各种阀的结构功能也了如指掌。 “你先看看阀体整体状况,再放入超声清洗机清洗一遍,然后检查一下气密性,问题应该就在这里。”……这可不是老赵在自言自语,这是“中国制动”微信群里回复同行的提问。在全路车辆制动系统技术骨干组建的“中国制动”微信群里,赵国文是重要一员。他经常针对提出的故障现象在群里发表自己的看法,提出解决方案,哪个部位、哪个零件出了问题,判断得八九不离十。 他不仅处理制动故障是”行家里手”,创新创效也是他的“拿手活”。从2016年7月份开始,制动室多了一项新任务——脱轨制动阀检修。就是防止车辆运行中脱离钢轨的一个装置。由于阀体外表不规则,用普通虎钳不易夹牢,分解起来既费时又费力而且不安全。赵国文看在眼里急在心里,只要一有功夫儿他就开始琢磨,认真观察职工分解过程,研究脱轨制动阀各零部件尺寸及连接方式,反复测量、比对,凭着一股钻劲儿,他用一个多星期成功研制成“脱轨制动阀分解机及专用工具”,解决了脱轨阀分解的大难题,职工们也高兴地把这个“发明”叫做“分解神器”!此创新项目荣获2016年度路局科技进步三等奖。2016年9月8日《北京铁道报》一版以“制动阀分解有神器”进行了专题报道。 老赵娴熟的技术是几十年工作经验的积累。制动阀分解、研磨、组装、试验等工序,他样样精通。30多年来,赵国文从一名普通工人成长为制动阀检修方面的专家,靠的就是日复一日的磨练,年复一年的积淀。 铁路货车制动阀从最初的K1、K2、GK、103到现在的120型,经历了4个阶段。许多职工都知道赵国文有个“宝贝”箱子,里面有他几十年来积攒下来的K1、K2、GK三通阀、安全阀等铁路货车制动机“老”配件。这些早已退出铁路历史舞台的“铁疙瘩”,他当作“宝贝”一样细心地收集起来。老赵常对人说“我是干不了几年了,现在年轻人越来越多,没见过以前铁路车辆配件的样子,我要把这些车辆配件拿出来,让他们看看我国铁路车辆的发展历程,珍惜热爱现在的工作,为铁路事业多做点儿贡献!” 如今,一走进制动室,干净整洁的制动阀展柜首映眼帘,老赵收藏的“宝贝”展出了!职工们围观着,述说着…… “一枝花开不是春,百花齐放春满园”,他经常带领班组同事学技术、讲经验。在他的带领下,班组荣获北京铁路局2016年“建功立业先进班组”称号,先后攻克了滑阀研磨、120阀主阀排气口漏气等多项惯性难题,获得了北京铁路局和北京市多项优秀QC成果奖。 老赵是个闲不住的人,这几年他常讲,“快退休了,留些念想儿,把自己多年来摸索出的检修技巧一定要传下去。”他,就是这样一位在铁路最基层岗位默默守护列车“心脏”的人……
