The present disclosure relates to a point rail and frog heel rail matching assembly for an assembled frog, and an assembled frog comprising same. The point rail and frog heel rail matching assembly comprises a point rail, which is provided with a center cross section making the point rail bilaterally symmetrical, wherein two grooves symmetrical with each other along the center cross section are arranged on a rear section part of the point rail; and two frog heel rails, which are arranged on two sides of the rear section part of the point rail in such a manner that same are symmetrical with each other along the center cross section, wherein the frog heel rails are provided with bosses fitted with the grooves; upper surfaces of the frog heel rails and an upper surface of the point rail are consistent in terms of height; edges of the upper surfaces of the frog heel rails extend backwards in the direction of an edge of an upper surface of a front section part of the point rail; and mutually abutting structures are arranged between the point rail and the frog heel rails, and are used for preventing the point rail and the frog heel rails from being pulled apart in the direction of the center cross section. In the present disclosure, by means of mutually abutting structures between slopes and bevels, a balance force can be created under the impact of a temperature force, so as to prevent displacement of the frog heel rails and the point rail, thereby solving the problem of bolt breakage resulting from the displacement.

A crossover switch, comprising: a first main line rail (101) and a second main line rail (102); a tongue rail (200), which is arranged between the first main line rail (101) and the second main line rail (102); a crossover rail (300), which is arranged at an outer side of the second main line rail (102); and a pull rod (400), which is used for connecting the tongue rail (200) and the crossover rail (300), wherein the tongue rail (200) and the crossover rail (300) are respectively hinged to the pull rod (400), and one end of the pull rod (400) is driven, by an electrical conversion device, to move the tongue rail (200) and the crossover rail (300) relative to a main line rail (100). By means of the provision of the tongue rail (200) and the crossover rail (300), the main line of the switch is a main running line of a train, and the speed at which the train passes thereon is high, such that the contact between a wheel and the tongue rail (200) which is weak in terms of strength is avoided, and the line and running safety of a train are facilitated, such that it can be ensured that the train smoothly passes through the main line at high speed; and the side line is an emergency avoidance line, and the speed at which the train passes thereon is relatively low, such that the side line is used only when necessary. The crossover switch has a simple structure design, is easy to process, manufacture and assemble, and has a relatively low maintenance workload.

The embodiments of the present invention relate to a rail brace and a rail brace system. The rail brace comprises a bottom plate, which is provided with a mounting slot extending through the middle of the bottom plate; a vertical plate, which is perpendicularly connected to the bottom plate and is arranged extending from the edge of a first side of the bottom plate away from a first face of the bottom plate; an elastic layer, which is arranged on an outer vertical face of the vertical plate and extends to the connection of the vertical plate and the bottom plate; and a supporting plate, which is perpendicularly connected to the bottom plate and arranged extending from the edge of a second side of the bottom plate away from a second face of the bottom plate, wherein the first side is arranged opposite the second side, and the first face is arranged opposite the second face. In the rail brace, providing the elastic layer enables the rail brace to be closely fitted to a rail after being assembled, thereby better enhancing the transverse rigidity of the rail, and reducing the problems of abrasion and safety caused by outward tilting of the rail due to insufficient rigidity. In addition, a certain damping function is provided, thereby reducing wheel-rail vibration noise.
