Abstract

The utility model relates to an oblique end rail which belongs to the improvement of the conventional rail. The end face of the oblique end rail is perpendicular to the top face of the oblique end rail and is obliquely crossed with the side face of the oblique end rail. Thus the intersecting lines of the end face and top face of the oblique end rail forms an intersecting angle alpha with the side of one side of the oblique end rail. The intersecting angle alpha is an acute angle with the range of 30 DEG to 60 DEG. The trackway of the railway, whose rail gap isn't perpendicular to the side of the trackway, is laid by the oblique end rail. Thus when train wheels passes through the rail gap, a buffering smooth transition is provided, which can lighten the impact against the end part of the railway. The noise is decreased at the time of the train running, and the service life of rail of the trackway is extended.

Description

Oblique end rail

The utility model belongs to the improvement of conventional track.

Usually track is formed by connecting for one section one section by railway track, and for solving the problem of expanding with heat and contract with cold of rail, the rail gap of certain width must be left in the joint between the rail.The rail limit is transversal to form because the end of present every railway track all is perpendicular to, and promptly the transversal limit of end causes each road rail gap of the track of being laid to become plumbness with the railway track limit perpendicular to its rail limit.And train is when moving on track, the contact edge of wheel and road rail level also is perpendicular to the track limit, wheel is by rail gap the time, joint end to rail produces bump, produces strenuous vibration when not only making train driving, makes a noise, particularly owing to the impact of wheel to end of rail, make the rail gap place produce depressed phenomenon, thereby bring very big difficulty to maintainer the application life of reducing wheel and rail greatly.According to parties concerned's statistics, railway of maintenance, the expense of flower on joint is to account for 40% of maintenance circuit full payment, with regard to the breakage of rail, the 60%th, occur in the joint.In recent years, though invented the problem that " spring secures rail to sleeper " and " anti-creep equipment " can't solve wheel bump rail gap fully.

The purpose of this utility model is at the drawback of existing railway track, proposes the splay end mouth railway track that a kind of port bevel forms, thereby makes when laying a railway track, and rail does not become plumbness with seam (rail gap) between the rail with the track limit.

The purpose of this utility model is to realize like this, the end of railway track is cut by bevel and is formed the splay end mouth, make the rail end face vertical with rail surface and with the side oblique of rail, the skew angle of rail end face and rail one side is a sharp angle, with the skew angle of its opposite flank then be the supplementary angle of α.Be that the rail end face becomes angle of cut α with the section line of end face with a side rail limit, with the angle of cut on opposite side rail limit then be the supplementary angle of α.

Usually the end face at rail both ends is parallel to each other, and the skew angle of an end face and a side is that the angle of cut α on rail end face and an end face section line and a side rail limit is 30～60 °, is the best with 45 °.

The utility model is because the side oblique of rail end face and rail, the rail end face does not become plumbness with the section line of end face with rail, thereby during with this steel rail laying track, rail and the rail gap that forms between the rail will be not vertical with the track limit, train wheel can cushion by rail gap the time and seamlessly transit, thereby avoids the hard hit of whole wheel to end of rail, alleviates the bump of wheel to rail gap greatly, not only reduce the driving noise, and prolong rail life.

Fig. 1 is the vertical view of the utility model railway track;

Fig. 2 is the railway track end face, is that Figure 1A-A is to sectional view;

Fig. 3 is the normal cross-section of rail, and promptly Figure 1B-B is to sectional view;

Track (only the showing monolateral rail) schematic diagram that Fig. 4 is laid for the utility model railway track.

(1) is that rail bed face, (4) are the rail gap of the track of laying, (5) are respectively rail both ends of the surface and rail surface for the sleeper of rail, CD, C ' D ' section line for the end face of rail, (2) for the side of rail, (3) among the figure.

The skew angle of rail end face and rail side is 45 ° among the embodiment, i.e. α=45 °, and both ends of the surface are parallel to each other, i.e. CD ‖ C ' D '.

Claims

1, cross section is the railway track of I shape, the end face that it is characterized in that end of rail vertical with the end face of rail and with the side oblique of rail, the section line of rail end face and end face and a rail limit acutangulate α intersects, with the angle of cut on opposite side rail limit then be the supplementary angle of α.

2, by the described railway track of claim 1, it is characterized in that the end face at rail both ends is parallel to each other, the skew angle of a rail end face and a side, promptly the angle of cut α on the section line of rail end face and end face and a side rail limit is 30 °～60 °.
