CN204212011U 一种60N新廓形钢轨道岔 有权

一种60N新廓形钢轨道岔
摘要：
本实用新型设计铁轨用道岔，具体为一种60N新廓形钢轨道岔。钢轨道岔基座上设置顶部轮廓，顶部轮廓具备有七段圆弧，体现为中段圆弧半径R为200毫米，右侧的圆弧半径R为60毫米，右侧的圆弧半径R为16毫米，右侧的圆弧半径R为8毫米，钢轨道岔顶部轮廓左右对称形成七段圆弧。本实用新型针对现有铁道行业标准生产的60钢轨，轨头廓形由5段圆弧该进为7段圆弧，相应的圆弧半径进行了优化，60N钢轨通过改善轮轨接触关系，可减轻钢轨伤损，从而延长钢轨使用寿命。
摘要（英）：

The utility model provides a turnout for a rail, and specifically provides a 60N new-profile steel rail turnout. The 60N new-profile steel rail turnout is characterized in that a top profile is formed on a base, wherein the top profile is equipped with seven arc sections; the medium arc is 200mm in radius R, the right arc in 60mm in radius R, the right arc is 16mm in radius R, and another right arc is 8mm in radius R; the seven arc sections are bilaterally symmetrically formed in the top profile. Compared with the 60 rail produced according to the existing railway industrial standard, the 60N new-profile steel rail turnout has the advantages that the five arc sections of the rail head profile are replaced by seven arc sections, the corresponding arc radius is optimized, the wheel-rail contact relationship is improved, the damage to the rail is reduced, and therefore, the service life of the rail is prolonged.
