铁路线路大修毕业论文设计论文.docVIP

摘 要 本设计是运用所学轨道基本理论，知识和技能，进行工程设计的综合训练，是综合素质和工程实践能力的重要体现，是每个学生都必须经过的作为一个铁道工程技术人员所必须的训练，有助于到工作岗位的过渡。 线路设备大修的基本任务是：根据运输需要及线路设备的损耗规律，有周期、有计划地对损耗部分进行更新和修理，恢复与增强轨道承受能力，延长设备的设备寿命。一般情况下，线路大修周期取决于钢轨伤损发展情况，是以全面更换钢轨为主要标志，故常称换轨大修。 线路换轨大修主要工作内容： 1.按设计校正改善线路纵断面和平面。 2.全面更换新钢轨及配件、钢轨伸缩调节器以及不合规定的护轮轨，更换绝缘接头及钢轨连续线。 3.更换失效轨枕和扣件，补足轨枕配置根数，修理伤损轨枕。 4.彻底清筛道床，补充道碴，改善道床断面。 5.线路大修地段，应同时成组更换新道岔和新岔枕。 6.安装轨道加强设备。 因涉及到的内容很多，所以利用电子表格EXCEL来进行计算，以达到更快、更准、更有效率的目的；其他内容也做到有的放矢。所有这些内容都参照我国现行的铁路线路维修规则和改扩建工程技术规范及工程制图规范书写的，符合国家标准。 关键词：大修；换轨；平面设计；纵断面设计 Abstract The graduation design as the last link of teaching plan, is the basic theory, use orbit knowledge and skills, project design, the comprehensive training is comprehensive quality and engineering practice ability, is the important embodiment of each student must pass a railroad engineers must training, helps to jobs. The basic task of the line equipment repair is: according to the transportation needs and lines of law, have cycle, planful part of loss, updated and repair recovery and enhance rail bear ability, prolong the service life of equipment equipment. Normally, line overhaul period depends on the rail.the development situation, based on comprehensive replacement for major rail, in particular said. Lines in overhaul main job content: 1.according to the design of the correction to improve line longitudinal peace. 2.the overall change new rail and accessories, trak controller and illegal armor wheel and rail, insulation joint replacement continuous line. 3.change failure sleeper and buckles, complemental sleeper, repair of configuration injury sleeper. 4.and thoroughly clear sieve solid, added ballastless track, improve section. 5.line, should also group overhaul and replacement of new nechanics new rail. 6.and strengthen equipment installation orbit. Because the content involves many, so use spreadsheet EXCEL to compute, faster and more accurate in order to achieve the goal, more efficient, Other contents and try to use computer colleg and use sof
