Abrégé

Provided in the present invention is a modular alloy steel frog. By means of modular optimization of a clearance space of the frog, and on the basis of ensuring the functions of the frog, modular processing is performed on key easy-to-damage areas, and an ingenious connection mode is set, such that the expectation of ultra-fast replacement is realized while ensuring the connection strength. Therefore, the service life of the frog can be greatly prolonged on the whole, and non-stop real-time replacement can be performed on key positions.

Abrégé

An embedded-member wing rail comprises a steel rail (2) and a steel alloy embedded piece (3) embedded at an inner side of the steel rail (2). The steel alloy embedded piece (3) and the steel rail (2) are in contact and match each other. A transition segment (5) of the steel alloy embedded piece (3) is a common bearing segment of a frog rail (9) and a wing rail (1). The steel alloy embedded piece (3) gradually rises from a frog throat to a frog heel end, and reaches an acute crossing (6) at the transition segment. A matching segment (4) of the steel alloy embedded piece (3) starts from the acute crossing (6) of the steel alloy embedded piece (3) and ends at an end of the steel alloy embedded piece (3). An edge of the steel alloy embedded piece (3) arranged towards a direction of the frog throat comprises a thin edge (7), and an edge of the steel alloy embedded piece (3) arranged towards a direction of the frog heel end comprises a round edge (8). The steel alloy embedded piece (3) and the steel rail match each other to enhance wear resistance of the wing rail (1), and the gradually increasing or decreasing structure of the steel alloy embedded piece (3) improves a loading state of the frog rail (9) and the wing rail (1), increasing a service life of the frog.
