Opposite insertion type steel rail expansion joint
A metro and high-speed rail steel rail thermal expansion and cold contraction opposite insertion type steel rail expansion joint is simple in structure, safe, reliable, convenient to maintain and suitable for being used for connection of high-speed rail and metro steel rails in various areas. The opposite insertion type steel rail expansion joint has the biggest advantages that the mode that upper connecting rails are mutually crossed and butted is adopted, the expansion joint of the steel rail joint is divided into two halves at different front and back positions, and when a train runs at a high speed, noise generated when the train collides with a railhead joint by wheels of the train in the past is avoided. Meanwhile, the width of the rail waist of the middle rail of the opposite insertion type steel rail expansion joint is increased, so that the safety problem of stress deformation during high-speed running of the train cannot be influenced, and the problem of thermal expansion and cold contraction of the high-speed rail steel rail is well solved. The oppositely insertion type steel rail expansion joint not only reduces the construction cost of a high-speed rail and improves the construction speed of the high-speed rail, but also greatly reduces the maintenance cost of the high-speed rail.
本发明的一种地铁、高铁钢轨热胀冷缩对插式钢轨伸缩接头，结构简单，安全可靠，维护方便，适合各个地区高铁、地铁钢轨的连接使用。这种对插式钢轨伸缩接头最大的优点就是，采用了上连接轨相互交叉对接的方式，将钢轨接头伸缩缝分开成两半前后不同位置，在列车高速行驶时也不会产生与以往列车车轮撞击轨头接缝的哐当声音。同时加厚了对插式钢轨伸缩接头中部轨轨腰的宽度，这样就不会影响列车高速行驶时受力变形的安全问题，这样就很好的解决了高铁钢轨热胀冷缩的问题。这种对插式钢轨伸缩接头不仅节省了高铁的建设成本，提高了高铁的建设速度，而且大量减少了高铁的养护费用。
