Alloy Steel Rail Assembled Frog
Forged alloy steel point rail combination frog point rail is made of forged alloy steel billets. Its point rail component is made of the point rail and two fork heel rails, and the fork heel rail and wing rail are made of rolled common section rails; The rail piece is bound as a whole through the cooperation of spacer and bolt. See Figure (a) for site laying.
The center rail assembly of the welded wing rail reinforced alloy steel composite frog is a combination of the center rail and two fork heel rails. The center rail is made of forged alloy steel billets, and the fork heel rail is made of ordinary section rails; In order to improve the strength of the wing rail at the position corresponding to the weak section of the center rail, one section of alloy steel is used to make the wing rail, so the wing rail is a weldment of ordinary rail and alloy steel rail; The rail piece is bound as a whole through the cooperation of spacer and bolt. See Figure (b) for site laying.
The center rail assembly of alloy steel rail composite frog is a combination of long center rail and short center rail. The long center rail is made of rolled alloy steel rail, and the wing rail is a common section rail or bainite rail; The rail piece is bound as a whole through the cooperation of spacer and bolt. See Figure (c) for site laying.
The center rail component of the embedded wing rail type alloy steel composite frog is a combination of the center rail and two fork heel rails. When the center rail and the wing rail insert are of an integrated structure, the center rail will assume some functions of the wing rail; When the fork center and the wing rail insert are not in an integrated structure, the wing rail and the insert are matched together; The center rail and insert block of the structure are made of alloy steel; The rail piece is bound as a whole through the cooperation of spacer and bolt. See Figure (d) for site laying.
Forged alloy steel point rail composite frog, welded wing rail reinforced alloy steel composite frog and alloy steel rail composite frog have compact structure and smooth wing rail top bend transition, but there is deviation from the ideal design value in the current rail top inorganic processing; The embedded wing rail type alloy steel composite frog is transited by setting inserts on the wing rail, which is easy to cause uneven rail transition, and the structure is loose compared with the above three structures, but the profile of the inserted rail top after processing is more reasonable.
