Abstract
The utility model provides a novel rail, and the clearance at a rail joint between the rails is firstly lateral and secondarily longitudinal. When wheels run on the railway built by the rails, the impact between the wheels and the rails is very little and even as little as none, and the running speed of a train can be improved greatly with good stability. The body of the rail is a double T-iron extending longitudinally, each end of the rail is in the form of a ladder which divides steps laterally, and through holes are arranged on each ladder face.
Description
Technical field
The utility model relates to a kind of railway track.
Background technology
Existing rail is an i iron that extends longitudinally.When building railway,, when connecting between each one steel rail, vertically to leave the gap for the needs that expand with heat and contract with cold.Because this axial clearance is vertical with the direction of advance of wheel, has not only hindered the wheel operation, and cause wheel and rail to produce powerful impact, the travel speed of vehicle is subjected to very big restriction.
Summary of the invention
The purpose of this utility model provides a kind of novel rail, the gap of the junction between its rail is mainly being auxilliary laterally, vertically, wheel travels on this rail, impact between wheel and the rail is very little, even do not impact, the travel speed of vehicle can improve greatly, and its stationarity is fine.
This rail, main body are the i iron that extends longitudinally, and i iron comprises top steel plate, bottom steel plate and the middle floor that top steel plate, bottom steel plate are linked into an integrated entity, and end of rail is along the stairstepping of horizontal sublevel, and through hole is arranged on the cascaded surface.
When using this rail, with the dislocation of the end of two one steel rails relatively, make the cascaded surface on two one steel rails relative, pass through hole on the cascaded surface of two one steel rails with bolt then, two one steel rails can be coupled together.Connect the back railway track, the gap on two one steel rails between the relative cascaded surface is the cross direction profiles along rail, this gap be parallel to rail vertically, consistent with the wheel direction of advance, can not cause obstacle to advancing of wheel.
Axial clearance between two one steel rails, want much shorter (width of axial clearance between the existing rail and top steel plate is with wide) with respect to the axial clearance between the existing rail, the more important thing is, wheel is by this axial clearance the time, the part of wheel also is supported on the rail, so the impact between wheel and the rail is very little, even does not impact, its travel speed can improve, and its stationarity is fine.
As further improvement, the middle floor of end of rail step shape part and the top steel plate on its top are with wide.We know, existing rail, the i iron of its main body, and the intermediate rib plate portion thinner thickness of i iron, so if end of rail is become stairstepping along horizontal sublevel, just thin originally middle floor will be separated again, it is thinner to become, and its intensity may just can not meet the demands.So, the middle floor of end of rail step shape part and the top steel plate on its top with wide be for after being divided into stairstepping, its intensity is still higher.
For rail recited above, described cascaded surface can be one, and it is by the longitudinal axis of rail.At this moment, the axial clearance between two one steel rails be the top steel plate width 1/2nd.Described cascaded surface also can be two, and they are divided the width on i iron top equally at the rail horizontal direction.At this moment, the axial clearance between two one steel rails be the top steel plate width 1/3rd.

The specific embodiment
Embodiment 1:
Rail x shown in Fig. 1-5 (or rail y), main body is the i iron that extends longitudinally, i iron comprises top steel plate 1, bottom steel plate 2 and the middle floor 3 that top steel plate, bottom steel plate are linked into an integrated entity.The both ends of rail x (or rail y) are that respectively there is a cascaded surface 4 at two ends along the stairstepping of horizontal sublevel.Cascaded surface 4 is by the longitudinal axis of rail, and has through hole 7.The middle floor 5 of end of rail step shape part 11 and the top steel plate 6 on its top are with wide.
When using this rail,, make the cascaded surface on two one steel rails relative, pass through hole 7 on the cascaded surface of two one steel rails with bolt then, two one steel rails can be coupled together the dislocation of the end of two one steel rails (referring to Fig. 6) relatively.Connect the back railway track, the axial clearance 9 between two one steel rails is 1/2nd of top steel plate 1 overall widths.Gap 8 on two one steel rails between the relative cascaded surface is the cross direction profiles along rail, this gap be parallel to rail vertically, can not cause obstacle to advancing of wheel.
Therefore wheel is by the axial clearance time, and the part of wheel also is supported on the rail, so the impact between wheel and the rail is very little, its travel speed can improve.Two axial clearances 9 can also solve the problem of expanding with heat and contract with cold.
Embodiment 2:
Rail x shown in Fig. 7-11 (or rail y), as different from Example 1: the both ends of rail x (or rail y) are the stairsteppings along horizontal sublevel, respectively there are two parallel cascaded surfaces 41,42 at two ends, are in the position that the overall width of top steel plate 1 is divided equally at two cascaded surfaces of horizontal direction 41,42.All have through hole 7 on the cascaded surface 41,42.The middle floor 51 of end of rail step shape part 111 and the top steel plate 61 on its top are with wide.The middle floor 52 of end of rail step shape part 121 and the top steel plate 62 on its top are with wide.
When using this rail, with the dislocation of the end of two one steel rails (referring to Figure 12) relatively, make on two one steel rails cascaded surface 41,42 respectively relatively, pass through hole 7 on the cascaded surface of two one steel rails with bolt then, two one steel rails can be coupled together.Connect the back railway track, the axial clearance 9 between two one steel rails is 1/3rd of top steel plate 1 overall widths.Gap 82 between gap 81 on two one steel rails between the relative cascaded surface 41, the relative cascaded surface 42 is the cross direction profiles along rail, this gap be parallel to rail vertically, can not cause obstacle to advancing of wheel.
