Elongated two the symmetrical grooves (11) that are shaped with on the two side of the web of the rail (8) of described alloy steel core rail (1), and the side that makes groove (11) forms the inclined-plane I (9) that the lower end tilts in the web of the rail, boss (12) is formed on the bottom of groove (11), makes the cross sectional shape of the web of the rail (8) form an approximate wedge shape; The inner face of wedge shape interval iron (4) is the inclined-plane II (10) closely connected with inclined-plane I (9), and the lower surface is the Planar Mechanism (13) closely connected with boss (12).
The vertical angle of described inclined-plane I (9) is 4 °～8 °.
Between described two wing rails (3), two forks with between the rail (2) and wing rail (3) and fork follow and be bolted respectively pair (6), rail packing ring (5) and general interval iron (7) between the rail (2) and be connected and fixed.
The advantage that the present invention compared with prior art has and effect:
1, the present invention stops alloy steel core rail to be difficult to upwards vibration by being used in conjunction with of wedge shape alloy steel core rail and wedge shape interval iron.In the upper track use procedure, when wheel forward or during reverse idle space by the intrinsic existence of alloy steel combination frog, the alternating stresses that the wheel impacts railway frog produces cause the relative wing rail of heart rail up and down the possibility of the changing of the relative positions greatly reduce, naturally can not cause bolt looseness yet, guarantee traffic safety, be beneficial to the maintenance of way.
2, the present invention is simple in structure, is easy to assembling, by being used in conjunction with of wedge shape alloy steel core rail and wedge shape interval iron, the alternating stresses of wheel impacts generation is converted into the pulling force of high-strength bolt, further lock bolt has strengthened the resistance to overturning of railway frog, the application life of having improved whole group of railway frog.
