Definitions

  • the invention relates to a railroad switch with y-shaped sleepers.
  • Steel sleepers have already been proposed for straight or curved tracks, which are formed from two approximately S-shaped curved steel profiles with straight ends. At the base of the Y, the two steel profiles are connected to form a support point for one rail, and the other two fork-shaped ends are carried out by parallel profile pieces to two further support points for the other rail (LU-PS 81116). Such y-shaped sleepers have been proposed in an alternating arrangement under the tracks.
  • One advantage of these Y thresholds is an increased resistance to lateral displacement.
  • switches with large teeth and standardized dimensions are required, the individual parts can be manufactured according to templates.
  • industrial railways order the substructure under the thresholds of the centerpiece more easily accessible, so that, for example, tamping a ballast bed with conventional tamping machines is possible.
  • the Y-shape of the sleepers results in such a high transverse displacement resistance that even with relatively narrow curves of switches, extremely long sleepers are not necessary.
  • all sleepers starting from the outer rail of the straight track are laid at right angles to this rail. This simplifies the preparation and assembly of the switch parts.
  • the ends of the sleepers projecting outward beyond the outer straight rail are expediently of the same length.
  • the sleepers can therefore be aligned in a simple manner.
  • the ends projecting over the curved outer rail may have a different length depending on the curvature. This aspect also helps to make do with a limited number of profiles.
  • I-profile steel should preferably be used as the threshold material, since this known elastic and stable I-profile shape can be rolled easily and inexpensively endlessly, can be dismantled into any lengths and is bent in an S-shape.
  • FIGS. 1a to 1c The arrangement of the sleepers for a left turnout is shown in particular in FIGS. 1a to 1c.
  • the thresholds are designated by the numbers 1 to 32, the threshold 1 itself lying in front of the switch and the threshold 32 already partially supporting the piece of track adjoining the straight track of the switch.
  • A denotes the tongue area which is only partially visible here, B approximately the frog area and C the area of the diverging glue track.
  • the rail parts of the switch correspond to the usual design.
  • 40 is the outer rail of the straight track
  • 41 the outer rail of the branching, curved track.
  • 42, 43 are the diverging rails of the two tracks from the centerpiece 44, which are called the inner rails here.
  • 45 and 46 are the switch tongues which can be moved by a device (not shown) arranged between the sleepers 2 and 3.
  • all further sleepers are composed of steel profiles in a Y-shape with the same S-shaped curvature.
  • the lengths of the straight ends of the steel profiles differ depending on their location, although the aim is to use several profiles of the same size.
  • the Y sleepers 1 and 19 to 23 are identical and the steel profile used for them is also used for sleepers 2, 3 and 4 with the same length and curvature.
  • the Y thresholds 4 to 18 are alternately laid out in a mirror bit arrangement.
  • the steel profiles 51 and 52 as well as the profile ends 57 and 58 arranged at their fork-shaped ends also support the movable tongues 45 and 46.
  • the sleepers 19 to 32 are laid in such a way that the fork-shaped ends lie under an outer rail 40 and 41, respectively.
  • the joined straight ends 53, 54 of the steel profiles support the two inner rails 42, 43.
  • the actual centerpiece 44 is advantageously elastically supported. It is also possible, for example, to tamp the ballast in the centerpiece area without difficulty and with conventional machines.
  • FIG. 2 and 3 show a Y-threshold 50 made of two oppositely S-shaped I-steel profiles 51, 52, the straight ends 53, 54, 55, 56 of which are parallel.
  • the threshold 1 from FIG. 1a was shown here, on which only a pair of rails is arranged; otherwise each sleeper carries three or four rail tracks within the switch.
  • straight I-profiles 57, 58 are arranged.
  • the profiles 53, 54 and 55, 57 as well as 56, 58 which are adjacent to each other at a certain distance are welded to one another by means of bolts 59, 60.
  • the spacing creates slots through which sleeper screws, in a manner not shown, are contained in a threaded hole and can be inserted between adjacent profiles or the like. be screwed in. Washer parts 61 and lateral guide plates 62 can be arranged between the upper bolts 59. The rail foot of the rails 63 is removed by means of tension clamps, not shown, under the sleeper screws aligns attached to the threshold 50.
  • All thresholds of the straight track protrude outward by the dimension a by the outer straight rail 40. This allows the Y thresholds to be aligned. At least for the straight rails, the fastening points can already be assembled on the sleepers before the switch is installed for the first time.
