CN2844195Y - Non-impacting vibrating steel rail against side sliding - Google Patents

Abstract

The utility model relates to a non-impacting and vibrating steel rail against side sliding, which belongs to a section bar of a traffic track with rails. Bottom and top end surfaces on both bottom and top ends of the steel rail are parallel to each other and are obliquely matched with a longitudinally vertical surface of the steel rail, and waist end surfaces on both ends of the waist of the steel rail are parallel to each other and are obliquely matched with the longitudinally vertical surface of the steel rail. The oblique directions of the end surfaces on both bottom and top ends and the end surfaces on both ends of the waist are opposite. The steel rail has the advantages of simple structure and side sliding prevention.

Description

No impact shock is prevented the sidesway rail

Technical field

The utility model belongs to a kind of track profile in the rail traffic, mainly is suitable for using in the vehicle means of transportation of operation at a high speed such as train etc.

Background technology

At present, the both ends of the surface of every railway track all are plane, and all become vertical angle with the rail longitudinal vertical plane.In the use, consider the physical phenomenon of expanding with heat and contract with cold, all leave flexible significantly slit in the junction of the rail that joins, its slit increase in winter.When the wheel of quick rotation through between rail during the shrinkage joint, wheel is actually in moment and breaks away from and the contacting of rail, from last one steel rail jump the back one one steel rail on, produce impact shock and noise significantly this moment, speed-raising operation along with train, the more apparent increase of impact shock and noise, although adopted long rail, problem does not solve at all.The applicant had once studied no impact shock rail, had tentatively solved vibration and noise problem, but because of the defective of structure design, when rail creeping produces dead seam, rail sidesway phenomenon occurred, had influenced applying of this rail.

Summary of the invention

The purpose of this utility model is exactly at structural defective of above-mentioned railway track and the technical problem of being brought, design provides a kind of no impact shock to prevent the sidesway rail, reach in the impact shock and noise when reducing the wheel high-speed cruising and contact at its shrinkage joint, eliminate the purpose of rail shifted laterally with rail.

Basic design of the present utility model is, the bottom and the top end face at rail foot, two ends, top are parallel to each other, and is tilted configuration with the longitudinal vertical plane of rail, and promptly angle is not equal to 90 °; The waist end face at rail waist two ends also is parallel to each other, and is skewed configuration with the longitudinal vertical plane of rail, and promptly angle is not equal to 90 °; The bottom at two ends and top end face are opposite with the waist end face tilt direction at two ends, so far constitute the anti-sidesway rail of no impact shock.

The utility model connects the end at rail and has realized vertically interconnection transition between end face, the location conditions each other laterally, solved the mutual dislocation problem when rail creeping produces dead the seam, prevent the shifted laterally between the rail, eliminate rail sidesway hidden danger, have simple in structure, security of operation characteristics stably, for vehicle speed-raising operation provides condition.

The specific embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The anti-sidesway rail of no impact shock comprises bottom 1, waist 3 and top 2, and the bottom 1 of rail, bottom, 2 two ends, top and top end face 5 are parallel to each other, and is skewed configuration with the longitudinal vertical plane 6 of rail, and promptly angle is not equal to 90 ° between it; The waist 3 two ends waist end faces 4 of rail are parallel to each other, and are skewed configuration with the longitudinal vertical plane 6 of rail, and promptly angle is not equal to 90 ° between it; The bottom at two ends and top end face 5 are opposite with waist end face 4 incline directions at two ends.

During steel rail laying, the bottom of its two ends end face and top end face 5, waist end face 4 match with another one steel rail end face respectively, have realized laterally moving between the rail control.

Claims (1)

1. A kind of no impact shock is prevented the sidesway rail, comprise bottom (1), waist (3) and top (2), the bottom (1), bottom, two ends, top (2) and the top end face (5) that it is characterized in that rail are parallel to each other, and be skewed configuration with the longitudinal vertical plane (6) of rail, promptly angle is not equal to 90 ° between it; The waist of rail (3) two ends waist end faces (4) are parallel to each other, and are skewed configuration with the longitudinal vertical plane (6) of rail, and promptly angle is not equal to 90 ° between it; The bottom at two ends and top end face (5) are opposite with waist end face (4) incline direction at two ends.
