Abstract
The utility model discloses a shock absorption railway rail which comprises two adjacent rails 1 and 5, a splice bar 2, a bolt 3 and a nut 4, and is characterized in that the length direction of the dilatation joint between the two adjacent rails 1 and 5 is not coincident with any vertical droop lines of the rail. When the wheel enters the dilatation joint between the two adjacent rails, the wheel is always contacted with the two rails, which avoids walking advancement, thus the vibration and the noise are reduced.
Description
Technical field
The utility model relates to a kind of railway track, particularly a kind of damping railway track.
Background technology
Because steel expand with heat and contract with cold, per two one steel rail joints must be provided with the shrinkage joint on the railway, the length direction at railway track shrinkage joint is vertical with the vertical vertical line of rail at present, during train operation, wheel is crossed the shrinkage joint in the mode of striding, thereby produces vibrations, sends noise, this not only makes the occupant be fed up with, and also gives application life of train and end of rail and brings adverse effect.
Summary of the invention
The purpose of this utility model is to provide a kind of damping railway track with damping effect, and it can reduce the vibrations and the noise that are produced when wheel is crossed the shrinkage joint.
For achieving the above object, the utility model improves the rail stroke seam, this kind damping railway track is made up of two adjacent rail, splice bar, bolt, it is characterized in that: the shrinkage joint length direction that two adjacent track bonds form does not overlap with the arbitrary vertical vertical line of rail.
Shrinkage joint length direction and the vertical vertical line of rail that above-mentioned two adjacent track bonds form have angle, and angle is 30 degree-60 degree.
Because the length direction at shrinkage joint does not overlap with the vertical arbitrary vertical line of rail, when making wheel through the shrinkage joint, contacts with two rail all the time, has avoided the mode of striding to advance, thereby train vibrations and noise are reduced.The utility model is simple in structure, with low cost, be particularly suitable for existing railway transformation.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the vertical view of the utility model embodiment;
Fig. 3 is the A-A sectional view of Fig. 1.
The specific embodiment
Embodiment: as can be known referring to accompanying drawing, a kind of damping railway track, it comprises two adjacent rail 1,5, splice bar 2, bolt 3, nut 4 is characterized in that: the shrinkage joint length direction that two adjacent rail 1,5 butt joints form does not overlap with the arbitrary vertical vertical line of rail, the inclination certain angle, this angle is advisable with 30 degree-60 degree.
As shown in Figure 2, when wheel had entered shrinkage joint between two adjacent rail, wheel contacted all the time simultaneously with two rails, has avoided step type to advance, thereby has reduced vibrations and noise.
By Fig. 1, Fig. 3 as can be known, it is in full accord that the connection form of two adjacent rail and the splice bar 2 that is adopted, bolt 3, nut 4 and existing railway line are adopted, thereby, be convenient on existing railway line, apply.
When laying new line, with the end of rail cutting forming, disposable installing; Rectification is during existing line, can by described structure in pairs the prefabricated part of filling up two adjacent rail are respectively prescinded one section at seam crossing, then the prefabricated part of filling up is in pairs welded up and gets final product.
Claims (2)
1. a damping railway track is made up of two adjacent rail (1,5), splice bar (2), bolt (3), nut (4), it is characterized in that: the shrinkage joint length direction that two adjacent rail (1,5) butt joint forms does not overlap with the arbitrary vertical vertical line of rail.
2. damping railway track as claimed in claim 1 is characterized in that: shrinkage joint length direction and the vertical vertical line of rail that two adjacent rail (1,5) butt joint forms have angle, and angle is 30 degree-60 degree.
