Abstract

The present invention relates to a rail for railroad tracks, and more particularly, in order to extend the service life of rails installed on tracks such as trains or subways as much as possible,

In the rail for railroad tracks fixed by the fasteners to the upper surface of the fixing plate fixed to both sides of the sleeper, the rails can be operated in contact with the wheels of the train or subway by the connecting portion formed in the middle of the upper and lower The rail surface of the rail is correspondingly integrally formed, and the mounting groove corresponding to the rail surface is formed on the upper surface of the fixing plate.

The present invention relates to a rail for railroad tracks, and more particularly to a rail for railroad rails that can be used to extend the service life of the rail is installed on the track, such as a train or underground railway.

The rail installed in the conventional track configured as described above operates in contact with only one side surface of the rail surface of the train or subway, that is, the wheels are in contact with only one side surface starting from the middle of the rail surface. It is operated.

Accordingly, only one side of the rail surface due to the operation of a certain period of time will cause uneven wear, thereby positioning the rails on the sleeper so as to be able to use the other side of the unworn rail surface after a certain period of use. It was used to allow the train or subway to run on the other side of the rail where no wear occurred.

Therefore, it has the advantage of being able to use it for a long time by making it possible to use both sides of the rail surface on the same surface for the usage period of the said rail.

However, the rail used as described above is a metal material having a long length in which connecting portions or fixing flanges are integrally formed in addition to the rail surface, and thus the use of the rail may not be reused after the use of the rail surface formed on the upper portion is completed. Had an extremely low problem.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object of the present invention is to maximize the utilization by extending the service life of the rail installed on the track of the railway as possible.

Another object of the present invention is to allow the rail to be more closely fixed to the fixing plate.

Another object of the present invention is to make it easy to check the state of wear.

The present invention for achieving the above object, in the rail for railroad tracks fixed by the fastener to the upper surface of the fixing plate fixed to both sides of the sleeper, the rail is train by the connecting portion formed in the middle of the upper and lower Or each rail surface that can be driven in contact with the wheels of the subway is formed integrally corresponding, characterized in that the mounting groove corresponding to the rail surface is formed on the upper surface of the fixing plate.

The bottom surface of each rail surface in contact with the connecting portion is characterized in that formed in each inclined surface.

The middle of the rail surface is characterized in that each identification groove having a predetermined depth is formed so as to confirm the wear level of the rail surface.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in more detail as follows.

1 is an exploded perspective view of a main part of the present invention, FIG. 2 is a perspective view of a main part in a coupled state according to FIG. 1, and FIG. 3 is a schematic cross-sectional view of a main part of FIG. 2.

Rails for railway tracks that are fixed by the fasteners 122 to the upper surface of the fixing plate 120 is fixed to both sides of the conventional sleepers 110 so that the wheel of the train or subway can be raised by running ( 100),

The present invention, each rail that can be operated in contact with the wheels of the train or subway by the connecting portion 104 formed in the middle of the upper and lower in order to be able to use the rail 100 for a longer period of time. The surfaces 10 and 10a are integrally formed to correspond to each other, and the mounting groove 20 corresponding to the rail surfaces 10 and 10a is formed on the upper surface of the fixing plate 120.

The bottom of each rail surface (10, 10a) in contact with the connecting portion 104 is closer to the upper surface of the fixing plate when using a fastener to fix the rail when the fastener is inserted into the fixing plate is fixed to a greater holding force It is preferable to form each of the inclined surface 12 to have a close fixing force to have a.

In the middle of the rail surface (10) (10a) is a check groove (30) having a certain depth so as to easily check the wear level of the rail surface (10) (10a) in contact with the operation of the train or subway By forming, it is desirable to enable the operator to easily check the worn state of the rail surface without any hassle so that the position and replacement time of the rail can be quickly identified.

On the other hand, when fixing the rail of the present invention as the upper surface of the fixing plate by the fastener, the fastener 122 is more closely contacted by the inclined surface 12 formed as the bottom surface of each rail surface (10, 10a). As the conditions are provided, the conditions can be fixed more tightly and without fluidity.

In addition, a check groove 30 having a predetermined depth in the middle of the rail surface 10, 10a of the rail 100, that is, the wear level of the train or subway running on the rail surface, the operator can easily check with the naked eye. By doing so, the degree of wear of the rail surface can be checked quickly to have a condition that can be quickly located on the unworn rail surface or the replacement time can be easily confirmed.

As described above, the present invention forms upper and lower rail surfaces of rails installed to operate in contact with wheels of a train or subway on railroad tracks, thereby extending the service life of the rails by at least two times or more. Along with the effects that can be used, it also has the effect of having high economics.

In addition, the inclined surface formed by the bottom surface of each rail of the rail also has the effect that can be fixed more tightly without fluidity when fixing the rail with a fixed plate.

In addition, it is possible to easily check the worn state of the rail surface in the middle of each rail surface of the rail, it is possible to quickly change the position of the rail surface, and also has an effect that can be easily identified when the rail replacement.

Claims (1)

In the rail for railroad tracks fixed by fasteners to the upper surface of the fixing plate fixed to both sides of the sleeper, The rail 100 is integrally formed to correspond to each rail surface (10, 10a) that can be operated in contact with the wheel of the train or subway by the connecting portion 104 formed in the middle of the upper and lower, Rail for railroad line, characterized in that the mounting groove 20 corresponding to the rail surface (10) (10a) is formed on the upper surface of the fixing plate (120).
