Design method for elastic guard rail device of turnout switch rail
The invention discloses a design method of an elastic guard rail device of a turnout switch rail, which comprises the following steps: determining the transverse bearing capacity of the elastic guard rail device, determining the distance between a guard rail and a steel rail, and providing certain flexibility between the guard rail and the steel rail through an elastic support frame. The method has the effects of preventing the train wheels from derailing at the position of the turnout switch rail, reducing abrasion of the turnout switch rail, prolonging the service life of the turnout switch rail, enhancing the stability of the rail structure at the position of the turnout switch rail, improving the lateral turnout crossing stability of the train and reducing the rail engineering maintenance workload. The method is simple in step, easy and convenient to calculate and good in effect.
本发明公开了一种道岔尖轨弹性护轨装置的设计方法，通过确定所述弹性护轨装置的横向承载力、确定所述护轨和所述钢轨之间间距，通过所述弹性支撑架在所述护轨和所述钢轨之间提供一定的柔性，起到防止列车车轮在道岔尖轨位置的脱轨、减少道岔尖轨的磨耗、延长道岔尖轨的使用年限，增强道岔尖轨处轨道结构稳定性，改善列车侧向过岔平稳度，减少轨道工务维修工作量的作用，该方法步骤简单，计算简便，效果良好。
