Definitions
- the invention relates to a track with a rail section deviating from a normal basic course, in particular a cheek rail changed in its course by leading away from a track axis. Furthermore, the invention relates to a method for aligning a rail section of a track to a change of course which specifically deviates from the basic course of the track, in particular to form a change of course to avoid a grinding movement between wheels of a rail vehicle passing through the track and the rail section by changing the wheel contact point on the rail .
- the track axis can follow a straight line and or an arc, namely when the switch itself is located in the curve of a track.
- the depth of the bulge can be between 5 and 30 mm. Due to the small deviation from the basic course, work must be carried out with high precision in order to set the desired course change and thus avoid a grinding movement between wheel and rail.
- the present invention is based on the problem of developing a track or a method for aligning a rail section of a track of the type mentioned at the outset in such a way that an exact alignment of the course of the rail section can be checked using structurally simple measures.
- the problem is solved in that the rail section has a recess running in the longitudinal direction of the track and parallel to its basic course, the course of which is opposite to the desired change in course when the rail section is arranged parallel to the basic course.
- the rail section which is to be subjected to a desired change in course is first aligned parallel to the basic course, in order to then cut and mill a recess in the longitudinal direction, preferably in the rail head, on the side opposite the running edge, the depth corresponding to the desired change in course varies, namely following a curvature that runs opposite to that in the installed state of the rail section.
- an alignment is now required such that the recess with its surface running parallel to the driving edge or the rail web runs parallel to a measuring straight line, the rail section making the desired change in course corresponding to the orientation of the reference surface of the recess like a groove bottom on a straight line - or an arc.
- this recess should increase with increasing groove depth in the direction of the rail head running surface.
- the recess runs in a rail head side flank, it is provided that this begins at the beginning of the change in the course of the rail section approximately 10 to 20 mm, preferably 12 to 16 mm, in particular approximately 14 mm below the rail head travel surface.
- the recess in its boundary wall running parallel to the rail web should have a distance from the rail head driving surface which is 5 to 5.5 mm, based on a maximum course change to a basic course in the form of a straight line of 10 to 20 mm.
- the cut-out which enables the desired change in course to be checked in a simple manner, should be a step machined and milled in the rail head flank, the step having a side delimitation surface that runs perpendicular to the rail web, and whose bottom surface running perpendicular or almost perpendicular to the side delimitation surface extends up to The top of the rail head extends.
- a measuring line is arranged along the rail section parallel to the basic course, that the distance between the measuring line and the recess is used to align the rail section with the desired change in course or whose floor is parallel to the central axis of the rail section is measured and that the distance between the measuring straight line and the recess or the floor of the rail section has the desired change in course with a constant distance value over the entire length of the rail section.
- FIG. 3 shows a section along the line AA in FIG. 1,
- Fig. 4 is a section along the line GG in Fig. 1 and
- FIG. 5 shows a section along the line SS in FIG.
- the wheel contact point of a person passing through a track can Rail vehicle in the area of a switch are influenced by the fact that the stock rail undergoes a targeted change in course by moving away from the track axis, as a result of which a grinding movement between wheel and rail is largely avoided.
- Corresponding changes in course can be between 5 and 30 mm due to bulges of the stock rail.
- the teaching according to the invention provides that a rail section 10 to be subjected to a change in course is initially aligned parallel to the basic course, that is to say in particular a straight line.
- the corresponding rail section 10 is shown in plan view in FIG. 1.
- edge 18 is the driving edge when rail section 10 is installed.
- a groove or step extending in the longitudinal direction of the rail section 10 is worked out in the rail head 15 on the side of the edge 20 in its second flank 22, milled, the bottom or base surface 26 of which runs parallel to the central axis of the rail, that is to say parallel to the web 14, undergoes a curved course such that when the rail section 10 is bent outwards in the exemplary embodiment (upwards in the drawing), the groove bottom or reason 26 is aligned parallel to the usual basic course, as is illustrated by FIG. 2.
- the groove base 26 or a corresponding reference line for the rail section 10 following the basic course and the driving edge 18 for the desired change in the course of the following rail section 10 run mirror-symmetrically to a straight line running parallel to the basic course.
- the recess 24, ie the bottom 26 thereof, has a geometry that is opposite when the rail section 10 is aligned with the basic course is the same as the curved course of the rail section 10 corresponding to FIG. 2.
- the rail section 10 has the desired change in course, that is, in a switch, a stock rail has a bulge outwards away from the switch tongue, it is only necessary that a measuring line is arranged parallel to the basic course and the distance between this and the Groove bottom or bottom 26 is checked. If the distance Y between the measuring line and the groove bottom 26 is the same, it is ensured that the rail section 10 has the desired change in course.
- the groove 24 increases with increasing depth towards the driving surface 16, as is illustrated by the sectional representations of FIGS. 3 to 5.
- FIG. 3 shows a section of the rail section 10 in the region of the basic course, which is not changed even after the rail section 10 has been bent.
- the rail head 15 has a customary geometry.
- the groove or step 24 is milled at a distance X from the zero point NP thus formed, the distance to the zero point NP decreasing as the groove depth increases, as FIGS. 4 and 5 illustrate.
- the distance T or V. of the foot-side boundary surface 28 running perpendicular to the web 14 is reduced with increasing groove depth, while increasing the distance U or W. the floor 26 running between the side flank 22 and parallel to the web 14 to the rail head travel surface 16 is reduced.
