Definitions

  • the invention relates to a rolling device for supporting the tongue of a switch according to the preamble of patent claim 1.
  • switch rib plates When moving the switch tongues on switches, switch rib plates are used. Such switch rib plates carry a sliding chair, which is equipped with the appropriate material and lubrication so that the switch tongue can be slid with its underside on the sliding chair. In order to be able to transmit the wheel forces securely to the threshold in the turnout area, it is necessary that the turnout tongue rests on the sliding chair as far as possible.
  • a disadvantage of conventional switch rib plates with a normal sliding chair is that, due to the sliding friction, which also depends on the condition of the lubricant, high adjustment forces have to be applied when adjusting the switch. In addition, the sliding chair wears out quickly due to dirt. It is therefore proposed in DE 40 41 242 A1 to arrange rollers next to the sliding chair which, when the switch tongue is moved away from the stock rail, lift it off the support of the sliding chair.
  • the construction shown here is very complex.
  • the invention is based on the object of safely designing a rolling device according to the preamble of patent claim 1 in a simplified embodiment, wherein a secure support of the switch tongue on the stock rail is ensured and an easy adjustment outside of this position is made possible.
  • the switch rib plate has a base plate 1 which is fastened via fastening means (not shown), for example threshold screws, which are screwed through fastening holes 2 to the threshold (not shown).
  • fastening means for example threshold screws, which are screwed through fastening holes 2 to the threshold (not shown).
  • the base plate 1 is with a Guide rib 4 formed on one side and a rail foot overlap 5 on the other side.
  • the rail foot overlap 5 is designed as part of the sliding chair 6.
  • Resilient fastening means not shown, position the stock rail 3 on the base plate 1 and hold it down.
  • the sliding chair 6 has a width corresponding to the width of the foot of the switch tongue 7.
  • the stock rail 3 and the switch tongue 7 are shown in the closed position.
  • the opening position of the switch tongue 7 is shown in dashed lines.
  • Figure 2 only the center line of the stock rail 3 is shown.
  • a supporting rib 8 extends on the side of the sliding chair 6 facing away from the stock rail 3.
  • the surface of the supporting rib 8 lies slightly below the surface of the sliding chair 6.
  • Rollers 9 are arranged on both sides of the supporting rib 8. The axes of these rollers run in the direction of the stock rail extension. The rollers 9 protrude slightly above the sliding chair top 10. If the switch tongue 7 is thus displaced in the direction of the opening position shown in dashed lines in FIG. As a result, sliding friction quickly changes into rolling friction.
  • the number and spacing of the rollers 9 are chosen so that the switch tongue 7 is always clearly and preferably lying on two rollers.
  • the rollers 9 protrude laterally from the base plate 1 of the switch rib plate. This gives a free opening downwards in this area through which dirt and Snow can fall through freely. This design largely prevents the rollers from jamming, in particular due to icing, preferably when the rollers 9 project not only beyond the switch rib plate but also beyond the threshold.
  • the rollers 9 are rotatably held by axes 12. Securing means such as snap rings prevent the rollers 9 from being laterally displaced from the axles 12.
  • the axles 12 preferably do not protrude beyond the length of the rollers 9. They, including the securing means, are concealed in a recess 13 in the rollers 9.
  • the axes 12 are fastened in the support rib 8.
  • the rollers 9 can be adjusted in height within small limits by turning the axes 12.
