Definitions

  • the invention relates to a rail portion such as tongue rail, which merges into a connecting rail with inclined to the horizontal gradient, wherein the connecting rail and adjacent terminal side end portion of the rail portion have a same profile and the rail portion is connected to the connecting rail via a welded joint.
  • tongue rails are end-side bulged and butt-welded to a connection or control rail.
  • the tongue rail end and connection or control rail are flush with each other.
  • the tongue with its tongue end is supported on a horizontal surface. If the adjoining control rail slopes, a geometry course adaptation between the end of the tongue and the connecting rail is usually carried out in the welding area. This is possible in particular when a connection is made by means of aluminothermic welding.
  • a switch with spring tongue is known, which is welded to a forged fitting, which in turn allows a geometry adjustment to a connecting rail. Fitting and connecting rail are in turn welded, so that a total of two welds between tongue rail and connecting rail are required. As a result, not only an increased workload, but also a frequent check of the switch is required.
  • the present invention is based on the problem, a rail section, in particular tongue rail of the type mentioned in such a way that a problem-free adaptation of the geometry of rail section and connecting rail is made possible without requiring reworking on the rail section itself.
  • the problem is essentially solved in that the rail section has in its connection-side end region a geometry curve corresponding to the connection rail and is connected to the exclusion rail via a single welded connection. This applies both in relation to the rail head and the web and the rail foot.
  • the geometry adjustment is not placed in the welding area, but spaced from this in a transition region, in particular in a tongue rail in the transition region between the tip side tongue profile and rule rail side end portion of the tongue rail.
  • the geometry adjustment takes place in the rail section as tongue root itself.
  • an adjustment of the profile of the rail section to a connecting rail with high inclination is easily possible.
  • a butt welding of rail section such as tongue rail and connecting rail such as control rail can be done without difficulty, without a change in the course must be laid in the welding area, also can not be compensated by such a large difference in inclination.
  • this could also be a tab connection, since according to the invention the geometry change does not run in the connection area.
  • only a welded joint between tongue and connecting rail is required, whereby a high load exposable rail section such as switch is provided.
  • connection-side rail portion may be supported on a surface corresponding to the terminal rail.
  • connection-side end already has a geometry profile over a region B, in particular B ⁇ 100 mm, which corresponds to that of the connection rail.
  • the reforged area itself may have a length of e.g. 500 to 2000 mm, even if the necessary length is essentially dependent on the type of geometry change.
  • the reforged intermediate region of the rail section allows a problem-free adjustment of the geometry of the rail end to the adjoining connection or control rail, without the need for machining the head itself. At the same time it is ensured that the rail section does not change in its driving edge course is, so that virtually the reforged area is "rotated" about the running edge, which corresponds to the driving edge course in the rail section area outside of the connection rail side end.
  • a tongue rail 10 is shown in side view, which forms a tongue forming the front portion 12, a transition region 14 in the form of z. B. a deflagration and an end portion 16 includes a profile corresponding to a subsequent connection or control rail, z. B. which can be butt welded by welding to the end portion 16 of the tongue rail 10.
  • the front tongue portion 12 is supported on a horizontal surface to deflect depending on its position wheels of a rail vehicle smoothly from a trunk track in a branch of a switch and vice versa.
  • connecting rail is inclined, so z. B. is supported on inclined to a horizontal surface extending, it must be ensured that the rail section 10 merges flush in its end portion 16 in the connecting rail, so with the same profile whose geometry or cross-sectional profile corresponds.
  • a geometry adjustment of the profile of the connecting rail to the tongue rail 10 by forming or Umschmieden the tongue rail 10 itself, in particular in the transition region 14, optionally also in the end region 16 such that a continuous change in geometry takes place such that a flush transition takes place in the connecting rail.
  • the running edge is not changed in the end region which changes in terms of its geometry.
  • the shaping such as forging the forging 14 in the direction of the end face 18, so the connecting rail quasi rotated about the driving edge 20, as is indicated in principle by the Fig. 2.
  • the view A illustrates that the end face 18 has an inclined foot 22 with a correspondingly inclined web 24 and inclined head 26, is rotated virtually around the running edge 20, wherein the geometry of the connecting rail corresponds.
  • the tongue rail 10 in its connection-side end 16 has a cross-section and a geometry curve corresponding to the connecting rail, wherein the rail feet are inclined identically and thus can be arranged on the same base plates.
  • a usual representation represented by a dot-dashed representation Arrangement with extending on a horizontal surface ab gandem rail foot 22 ', perpendicular thereto extending web 24' and corresponding rail head 26 'deviates.
  • the refilling can already end at a distance B from the end face 18, that is to say the welded connection region between the tongue rail 10 and the connecting rail.
  • the distance B is preferably more than 100 mm.
