摘 要:道岔是引导机车车辆由一条线路转向另一条线路的过渡设备。由转辙器、连接部分、辙叉及护轨3个部分组成,由于道岔数量多,结构复杂,与钢轨相比使用寿命短,限制列车速度,行车安全保障性低,养护维修投入大,也是股道的薄弱环节,与曲线、接头并称为轨道的3大薄弱环节。文章从7个方面分析了形成道岔病害的原因,并提出有针对性的预防及解决办法。Turnout is a transitional device that guides rolling stock from one line to another.It consists of three parts:switch,connecting part,frog and guard rail.Due to the large number of switches,complex structure,shorter service life than steel rails,limited train speed,low driving safety guarantee,and large maintenance and maintenance investment,it is also The weak link of the track,together with the curve and the joint,are called the three weak links of the track.The article analyzes the causes of turnout diseases from seven aspects,and proposes targeted prevention and solutions.
