Improved groove-shaped rail alloy steel point rail combined frog
The invention relates to the field of railway rails, and particularly relates to an improved groove-shaped rail alloy steel point rail combined frog. The frog comprises a combined point rail and wingrails. The combined point rail comprises a point rail and fork heel rails, the point rail is an alloy steel point rail, and the two fork heel rails are symmetrically arranged at a tail end of the point rail; the two wing rails are symmetrically placed on the two sides of the combined point rail; and the wing rails and the fork heel rails are composed of rail heads, rail grooves and rail lips at the top, rail webs in the middle and rail bottoms at the bottom. And the point rail, the wing rails and the fork heel rails are connected into a whole body through connecting bolt pairs. The wing railsand the fork heel rails adopt groove-shaped structures, and are connected with a line steel rail in the same rail type. A welding requirement of a seamless line can be met, a problem that a high manganese steel frog is difficult to connect with the existing line steel rail is solved, a frog product with high performance, a long service life and high safety performance is provided for railway departments, use, maintenance and repair cost of railway lines is reduced, and transportation benefits are increased.
本发明涉及铁路轨道领域，更具体的说，是涉及一种改进的槽型轨合金钢心轨组合辙叉。包括组合心轨和翼轨；组合心轨包括心轨和叉跟轨，心轨为合金钢心轨，叉跟轨有两根且对称设于心轨尾端；翼轨,有两根对称放于组合心轨两侧；翼轨和叉跟轨均由顶部的轨头、轨槽和轨唇，中部的轨腰，底部的轨底构成；心轨、翼轨和叉跟轨通过联结螺栓副连接为一体。本发明的翼轨和叉跟轨采用槽型结构，与线路钢轨联接同轨型联接，并可满足无缝线路焊接要求，解决高锰钢辙叉难与现路钢轨联接的问题，为铁路部门提供高性能，长寿命，高安全性能的辙叉产品，降低铁路线路的使用维修及养护成本，提高运输效益。
