Welding structure with double-inclined surface of no bumping and no vibration seamless rail with high load-bearing capability

摘要

A double inclined weld face structure for a jolt-and-vibration-free seamless rail with high bearing capacity relates to the welding of the seamless rail of the rail train, a weld seam of the rail according to the present application forms, at least partly, a double inclined weld face, forming an angle α with the vertical direction of the rail and an angle β with the transverse direction of the rail. The double inclined weld face can further improve the stress state in the weld face of the rail, enhance the bearing capacity of the weld face and eliminate upward and downward jolting and leftward and rightward shaking of a train. The double inclined weld faces of the two parallel rails (1) are arranged in a interleaving way and the interleaving length is greater than the length of a carriage, thus enhancing the running stability and durability of the train and more beneficial to use a simple existing Aluminothermic welding in the weld of the seamless rail.

1. A double inclined weld face structure for a jolt-and-vibration-free seamless rail which has high bearing capacity, comprising rails and weld seams, characterized in that the weld seams of the rails includes a double inclined weld face Aαβ formed on at least one part of the rail, the spatial relation between the double inclined weld face Aαβ and the rail (1) is that: a straight plane ABCD is a cross section A0 perpendicular to a longitudinal axis z, and a inclined plane ABEG, which is a single inclined cross section Aα, is achieved by rotating the straight plane ABCD an angle α about a vertical axis y, and an inclined cross section BEDH, which is a double inclined weld face Aαβ, is achieved by rotating the inclined cross section ABEG an angle β about BE edge; the angle α is formed between the double inclined weld face Aαβ and an axis x, and the angle β is formed between the double inclined weld face Aαβ and the vertical axis y; and
wherein the weld seam of the rails includes the double inclined weld face Aαβ formed on a rail head of the rail, and a single inclined cross section Aα′, which forms an angle α′ with the axis x, formed on a rail waist and a rail bottom of the rail.
