Definitions

  • the invention relates to a switch comprising travel rails, wing rails and a frog with the frog point reciprocable between the wing rails, wherein the rails and the wing rail are mounted on a threshold on which an adjusting device for adjusting the frog point is arranged, which via at least one line is connected to a drive device.
  • adjusting devices are required, which are connected via a connecting rod with the tongue rails. Adjustments are also required for switches with a centerpiece with movable frog tip for the conversion of the frog point between the two wing rails.
  • the adjusting device and the connecting linkage are usually between two thresholds, ie arranged in the so-called threshold compartment or in a hollow trough threshold, in which also a drive device, such as a hydraulic drive can be located.
  • a drive device such as a hydraulic drive can be located.
  • the arrangement of an adjusting device for a movable frog point together with connecting linkage in the sleeper compartment or in a trough threshold is for example in the EP 343150 A2 described.
  • trough sleepers require special provisions in the field of bulkhead installation, since trough sleepers must generally be used deeper than standard sleepers. Consequently, a separate Auskinateung the ballast at the installation site is required.
  • the present invention now aims to the in the DE 202010008526 U1 described type for the conversion of the movable frog point to adapt, with as little structural changes in the overall structure of the switch should be required.
  • the switch of the type mentioned is inventively developed such that the threshold is a concrete sleeper cuboid geometry with an upper side, the top limiting beveled longitudinal edges and outgoing from the longitudinal edges side surfaces, that the actuating device at the top of the threshold between a Ride rail and a wing rail is fixed, that the drive device is arranged outside the rails and preferably connected to the threshold that the at least one connecting the drive device with the actuator line along the slanted longitudinal edges, wherein the adjusting device, the at least one line and possibly the drive device extend within the threshold width.
  • a conventional concrete sleeper in particular a standard concrete sleeper, is used for fastening the drive and adjusting devices, wherein the components required for actuating the movable frog tip extend within the threshold width, ie in particular within an envelope, laterally from the concrete sleeper side surfaces or their extensions is limited.
  • the threshold width ie in particular within an envelope, laterally from the concrete sleeper side surfaces or their extensions is limited.
  • the construction is homogeneous, i. the sleepers stay the same throughout the turnout area, regardless of whether a drive for a moving centerpiece is provided or not.
  • the arrangement of the adjusting device, the at least one line and possibly the drive device within the threshold width here means preferably that the units in the normal projection do not protrude over the widest measure of the threshold.
  • the invention allows a simple installation of the switch, as no special precautions in the field of bulkhead installation are necessary, as is the case with steel trough sleepers, which must be used in principle deeper than standard sleepers. Furthermore, there are identical rail bearings and rail fastenings as in sleepers that have no points drive.
  • the drive device which is designed in particular as a hydraulic unit, is preferably connected to the concrete sleeper in an end region of the sleeper outside the rails, wherein a bracket may extend from the sleeper that extends beyond the front side of the concrete sleeper, thus providing sufficient space for securing the drive device to make available.
  • the width extension of the holder and the drive device is preferably selected so that they are basically within the width of the concrete sleeper.
  • the assembly height of both the adjusting device and the drive device is preferably selected so that a collision with the clearance gauge is excluded.
  • the drive device is designed as a hydraulic unit, is this is hydraulically connected via the at least one designed as a hydraulic line line with the actuator.
  • the hydraulic lines and according to the invention the connection linkage connecting the setting device and the movable frog tip are arranged within the width of the concrete sleeper.
  • the connection linkage emanating from the setting device also comprises, in addition to a control rod responsible for the changeover of the movable frog tip, also a checker rod for an end position test device.
  • the control rod and possibly the beautiestange are inventively passed below the rail foot of a wing rail.
  • the wing rail is formed with a reduced height relative to the frog tip and that the control rod and possibly the excerstange are passed through a space between the rail of the wing rail and the top of the threshold.
  • the control rod and possibly the strigerstange can be made straight here, i. without cranking, resulting in an optimal power flow.
  • the adjusting rod and optionally the excerstange preferably engage the rail of the frog tip.
  • control rod and possibly the excerstange each have a at least two-axis pivoting movement permitting swivel mechanism, in particular Ball joint, are hinged to the adjusting device.
  • control rod and possibly the excerstange are each articulated about a vertical pivot axis pivotally mounted on the rail of the movable frog tip.
  • connection of the linkage with the frog point is structurally in a particularly simple manner in that the control rod and possibly the kauerstange attack over a rail foot engaging around the clevis on the movable frog point.
  • An improved stability of the frog point is preferably ensured by the fact that the wing rails are formed with an asymmetric tongue rail profile.
  • the adjusting device, the wing rails and the frog point are not directly on the concrete sleeper, but on a base plate, which is optionally arranged with the interposition of an elastic base plate on the concrete sleeper.
  • the movable frog point is slidably mounted on the arranged on the threshold base plate, so that this base plate acts as a sliding chair for the frog point.
  • the base plate is preferably connected via at least one screwed into a recess of the concrete sleeper fastener with the concrete sleeper, wherein the adjusting device is connected to the concrete sleeper on the at least one fastener.
  • this does not exclude that further fasteners are provided, which may be screwed into separately introduced holes that emanate from the top of the concrete sleeper. Consequently, the adjusting device can not only be connected to it without changing the concrete sleeper shape, but additionally already existing ones can be connected to it Holes in the concrete sleeper are used to secure the actuator.
  • the preferably provided free space between the concrete sleeper and the underside of the rail foot of the wing rails is achieved in a structurally advantageous and space-saving manner, that attached to the base plate, a rail chair for supporting the wing rails, in particular welded.
  • the width of the rail chair preferably corresponds to at most half the width of the threshold, so that the control rod and possibly the excerstange can be guided laterally of the rail chair.
  • On rail chair preferably resort to means for low voltage and lateral support of the wing rails.
