Abstract

The utility model discloses a silencing rail which comprises I-beams composed of tracks and bases. The track is formed by combining a plurality of the I-beams. Connecting end faces of two adjacent I-beams are abutting oblique faces in corresponding fit. Processing holes for processing track abutting faces are formed in the middle waists of the I-beams. 45-degree acute angles are formed at the longitudinal sections of I-beam connecting ends above the processing holes. The acute angles extend towards the inner sides of the racks ahead of a running train. 90-degree right angles are formed at longitudinal sections of I-beam connecting ends below the processing holes. By the silencing rail, wheels are supported continuously without discontinuity points when passing expansion joints and can move stably from one I-beam to another, so that vibration and noise generated during advancing are greatly reduced, safe operation of the train is facilitated and service life of the train is improved; the upper portions of the rail are abutted in an oblique manner, and the lower portions of the rail are abutted in a right-angle manner, so that dislocation of oblique angles due to supernormal expansion of the rail in high-temperature summer can be avoided.

Description

The noise reduction rail

Technical field

The utility model relates to the transportation rail technical field, particularly a kind of noise reduction rail.

Background technology

The rail of railway transportation at present is all to be formed by connecting by a section i iron, the connecting end surface of adjacent two sections i iron is vertical with track length direction, the greatest drawback of this rail is: at the place, shrinkage joint of rail, rail is discontinuous to accepting of Train Wheel, cause wheel and rail to send very large shock sound, this not only produces larger resistance to travelling of train, easily make Train Parts become flexible and bring potential safety hazard, simultaneously under the weight of wheel, following rail there will be sinking, when directly causing again rail joint place and wheel to meet, this phenomenon sends huge noise.Existing design is the inclined-plane docking by the integrated connection end face of two lengths of rail, and this structure, in the extraordinary expansion of summer high temperature rail in season, easily makes oblique angle produce dislocation.

The utility model content

The purpose of this utility model is to carry a kind of noise reduction rail in place, and this rail can make wheel be subject to continuous support, reduce that wheel and rail bump against and the resistance and the noise that produce, can prevent under high temperature that the extraordinary expansion of rail produces oblique angle and misplaces.

The technical scheme the utility model proposes for achieving the above object is: a kind of noise reduction rail, comprise the i iron that track and base form, rail is to be connected to form by some sections i iron, the connecting end surface of adjacent two sections i iron is corresponding identical docking inclined-plane, and it is characterized in that: in i iron, waist has for processing the machining hole of orbital docking face; Longitudinal section acute angle at the above i iron link of machining hole is 45 degree, and this acute angle extends to the track of train operation ahead is inboard, in the longitudinal section of the following i iron link of machining hole, is 90 degree right angles.

The rail connected is suitable for unidirectional operation railway or two-way linear snipe.

The utility model has the advantages that: it is be subject to support continuously and there is no discontinuous point that the utility model makes wheel through shrinkage joint the time, can be transitioned into another root i iron from an i iron reposefully, greatly reduce the vibration and the noise that produce while advancing, make thus the passenger comfortablely ride, the application life that more is conducive to the safe operation of train and improves train; The first half of rail docking is the inclined-plane docking, and Lower Half is Corner butt joint, and this structure can prevent the extraordinary expansion of summer high temperature rail in season and make oblique angle produce dislocation.

In figure: 1 base, 2 tracks, 3 docking inclined-planes, 4 machining holes, 5 plywood holes.

The specific embodiment

Referring to Fig. 1～Fig. 3, the utility model noise reduction rail, comprise the i iron that track 2 and base 1 form, rail is to be connected to form by bolt and plywood hole 5 by some sections i iron, the connecting end surface first half of adjacent two sections i iron is corresponding identical docking inclined-plane 3, and in i iron, waist has for processing the machining hole of orbital docking face; Longitudinal section acute angle at the above i iron link of machining hole 4 is 45 degree, in the longitudinal section of the following i iron link of machining hole 4, is 90 degree right angles; Be more than the i iron machining hole, to be 45 degree acute angle bevel docking, machining hole is following is Corner butt joint, and this structure can prevent the extraordinary expansion of summer high temperature rail in season and make oblique angle produce dislocation.Adding man-hour is the machining hole 4 that waist is made a call to a diameter 30mm from i iron, then from the i iron top, with the miter angle vertical line, is switched to machining hole 4 downwards, more upwards is switched to machining hole with an angle of 90 degrees along vertical line from the i iron bottom.The acute angle on track 2 first halves docking inclined-planes 3 is to extend to the track of train operation ahead is inboard, and the rail that this design connects is suitable for the unidirectional operation railway, also is suitable for two-way linear snipe and is unsuitable for more turning highway section.

Claims

1. a noise reduction rail, comprise the i iron that track and base form, rail is to be connected to form by some sections i iron, and the connecting end surface of adjacent two sections i iron is corresponding identical docking inclined-plane, and it is characterized in that: in i iron, waist has for processing the machining hole of orbital docking face; Longitudinal section acute angle at the above i iron link of machining hole is 45 degree, and this acute angle extends to the track of train operation ahead is inboard, in the longitudinal section of the following i iron link of machining hole, is 90 degree right angles.
