Welded wing rail reinforced protection architecture used for railway track combined frog

Abstract

The invention relates to a railway track, aiming at providing a welded wing rail reinforced protection architecture used for a railway track combined frog. The reinforced protection architecture comprises a bolt assembly which is used for fixed connection; the main body of the reinforced protection architecture is a reinforced protection interval iron, and is in a long wedge-shaped structure; the longitudinal section plane along the center of the reinforced protection interval iron is in trapezoid; two ends thereof are respectively provided with a horizontally run-through bolt connection hole; the horizontal section plane along the center of the reinforced protection interval iron is a trapezoid; two slanting sides of the trapezoid are respectively attached to the internal edges of two welded wing rails; two sides of the welding line of the welded wing rail are respectively provided with a run-through bolt connection hole which is matched with the bolt connection hole on the reinforced protection interval iron. The welded wing rail reinforced protection architecture used for the railway track combined frog has reasonable design, simple structure and convenient processing, can be realized by slightly changing on the basis of the original combined frog, can improve welding line reliability of the combined frog welded wing ring, and better ensures traveling safe.

Description

technical field [0001] The invention relates to a railway track, in particular to a reinforced protection structure for a welded wing rail for a combined frog of a railway track. Background technique [0002] At present, the alloy steel composite frogs used in railway track frogs, due to the limitation of materials and structures, lead to serious wear and tear on the wing rails. There is a reinforced alloy steel composite frog. Welded wear-resistant alloy steel rails. Due to the different materials of the two sections of welded rails and the possibility of various unstable accidental factors in the welding process, in order to avoid cracks and defects in the weld seam that would lead to disintegration and fracture of the welded wing rail, and to ensure driving safety, it is necessary to design a welding Wing rails reinforce the protective structure. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficienc...
