Extreme weather-resistant rhombus turnout formed by welding three materials
The invention discloses an extreme weather-resistant rhombus turnout formed by welding three materials, which comprises a fork core, steel rails and alloy steel rail legs; the alloy steel rail legs extend in the running direction of a vehicle; the cross section of the alloy steel rail leg is larger than that of the steel rail; the alloy steel rail legs are welded on the fork core; rail leg rail grooves matched with the fork core rail grooves in the fork core are formed in the top of the wear-resistant alloy steel in the same direction; the steel rails are welded to the ends of the alloy steelrail legs, every two alloy steel rail legs are connected to form a rhombus turnout, the alloy steel rail legs are fixedly connected through a clamping plate connecting structure, and the distance between the ends of every two connected alloy steel rail legs is smaller than 8 mm. Due to the fact that the section of the alloy steel rail leg is large, the deformation quantity generated by thermal expansion and cold contraction in the length direction is reduced, the steel rail seam at the joint can be reduced, and the influence of extreme weather is small.
本发明公开了一种三种材料焊接制成的耐极端气候的菱形道岔，包括叉心、钢轨和合金钢轨腿，所述合金钢轨腿沿车辆行驶方向延伸，所述合金钢轨腿的横截面大于所述钢轨的横截面，所述叉心上焊接有所述合金钢轨腿，所述耐磨合金钢顶部同向开设有与所述叉心上的叉心轨槽配合的轨腿轨槽，所述钢轨焊接在所述合金钢轨腿端部，所述合金钢轨腿两两连接形成菱形道岔，所述合金钢轨腿之间通过夹板连接结构固定连接，且相连的两个所述合金钢轨腿的端部之间的距离小于8mm。本发明由于合金钢轨腿截面较大，热胀冷缩在长度方向上产生的形变量减少，这样连接处的钢轨轨缝就可以减小，受极端气候影响较小。
