Definitions

  • the invention relates to a rail section such as tongue rail, the with a connecting rail with a rail base inclined to the horizontal and inclined running surface is connected by welding and flush into the Connection rail merges.
  • Tongue rails commonly used nowadays are at the ends removed and butt welded to a connection or control rail. Go there The end of the tongue rail and the connecting or regulating rail are flush with one another. The The tongue with its tongue end is supported on a horizontal surface. Runs the adjoining control rail is inclined, so is usually a geometry adjustment between the tongue end and the connecting rail in the welding area. This is particularly possible if a connection using aluminothermic Welding takes place.
  • a switch with spring tongue is known, which with a forged
  • the fitting is welded, which in turn adapts to the geometry a connection rail enables.
  • the fitting and the connecting rail are welded in turn, so that a total of two welds between the tongue rail and the connecting rail required are. This means not only increased workload, but also a frequent check of the turnout is required.
  • the problem underlying the present invention is a rail section, in particular tongue rail of the type mentioned in such a way that a easy adaptation of the geometry of the rail section and connecting rail is made possible without reworking the rail section itself requirement.
  • the problem is essentially solved in that the rail section in its connection-side end area one corresponding to the connection rail Has geometry course. This applies to both the rail head as well as the bridge and the rail foot.
  • the geometry adjustment does not deviate from the known prior art in the welding area, but spaced apart from this in a transition area relocated, especially with a tongue rail in the transition area between tip-side tongue profile and control rail-side end area of the tongue rail.
  • the geometry is adjusted in the rail section like the root of the tongue itself.
  • a tab connection could also be used take place, since according to the invention the change in geometry is not in the connection area runs. Furthermore, there is only a welded connection between the tongue and connecting rail required, resulting in a rail section that can be subjected to high loads how turnout is made available.
  • connection-side rail section can thus be supported on a surface that corresponds to the connecting rail.
  • connection-side end has a region B in particular B ⁇ 100 mm already has a geometry that corresponds to that of the connecting rail.
  • the forged area itself can have a length of e.g. 500 to 2000 mm have, regardless of whether the necessary length depends essentially on the type of geometry change is dependent.
  • the forged intermediate area of the rail section enables a problem-free Geometry adaptation of the rail end to the subsequent connection or Control rail without the need to machine the head itself. At the same time ensures that the rail section does not change in its running edge course is, so that the forged area is "rotated" around the driving edge, the the running edge course in the rail section area outside the connection rail side End corresponds.
  • a tongue rail 10 is shown in side view, the one Tongue-forming front section 12, a transition region 14 in the form of z. B.
  • one Forging and an end portion 16 includes a profile that one subsequent connection or control rail corresponds, for. B. by welding with the end section 16 of the tongue rail 10 can be butt welded.
  • the front tongue portion 12 is supported on a horizontal surface to be dependent from its position wheels of a rail vehicle shock-free from one To divert the main track into a branch track of a switch and vice versa.
  • connecting rail is inclined, i.e. on z. B. on to a horizontal supported inclined surface, it must be ensured that the rail section 10 in its end region 16 merges flush into the connecting rail, that is, at same profile whose geometry or cross-sectional profile corresponds.
  • connection rail is significant Inclinations of z. B. 1:20, it is no longer possible to use the corresponding Lay geometry adjustment in the connection area, without disadvantages in Passing through the transition area between the tongue rail and the connecting rail in To take purchase.
  • this can be ruled out, especially for high-speed tracks.
  • a forged one can be inserted between the tongue rail and the connecting rail Intermediate part to be welded to adapt the geometry.
  • there are two weld seams which lead to considerable disadvantages such as material changes or cause bumps in the process trains.
  • the geometry of the course of the connecting rail is adjusted to the tongue rail 10 by reshaping or forging the tongue rail 10 itself, in particular in the transition area 14, possibly also in the end area 16 such that there is a continuous change in the geometry course such that a flush transition into the connecting rail.
  • the forging is used in the shaping like forging 14 in the direction of the end face 18, that is to say the connecting rail to the Driving edge 20 rotated, as is indicated in principle by FIG. 2.
  • the tongue rail 10 has a cross section in its connection-side end 16 and a geometry course that corresponds to the connecting rail, the Rail feet are inclined identically and thus arranged on the same base plates can be.
  • This results in a change in the course of the geometry which is recognizable by a usual representation represented in principle by a dashed line Arrangement with a rail foot supported on a horizontal surface 22 ', web 24' running perpendicularly thereto and corresponding rail head 26 ' deviates.
  • the forging can already be at a distance B from the End face 18, ie the welded connection area between the tongue rail 10 and Connection rail ends.
  • the distance B is preferably more than 100 mm.
