Zusammenfassung: | 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. |
