Definitions

  • the invention relates to a changeover device for rails pivotable about a pivot axis or movable frogs in the crossover area of a switch.
  • a continuous driving edge in the desired direction of travel can be achieved by, for example, bringing wing rails into contact with a rigid centerpiece, with one of the two wing rails being brought into contact with the centerpiece and the opposite one depending on the direction of travel in the crossover area Wing rail is lifted off on the same side of the centerpiece.
  • conventional adjusting devices have been previously proposed, as are usually used in switch construction. Such actuators have angle levers and push rods and are relatively complex to construct. Due to the large number of joints in such adjusting devices, such adjusting devices can in no way be used directly to support the correct position of movable rails in the crossover area of a switch.
  • a support rod was provided for the support, which can extend over several sleepers and in this way can also maintain a support if there are differences in length due to temperature fluctuations.
  • the switch adjustment was carried out in this known design according to AT-PS 328 488 in a known and conventional manner and analogously, the wing rails were adjusted.
  • the invention now aims to provide a changeover device for rails pivotable about a pivot axis or movable frogs in the crossover area of a switch, with which it is possible not only to change the respective moving parts, but also to provide effective support and exact verifiability ensure the selected swivel position.
  • the invention essentially consists in the fact that the pivotable rails or movable frogs in the longitudinal direction of the rails, which are displaceably guided on the sleepers or base plates in the longitudinal direction of the rails or frogs, in their alignment with wing rails or connecting rails or supported position, and that the support rods are designed as an actuator for the changeover and have at least one thrust support, which cooperate with thrust supports of the pivotable rails or the frog, wherein at least one of the interacting surfaces of the thrust supports of the rail or frog and / or support rod is formed by a wedge surface which merges into a support surface which is essentially parallel to the longitudinal direction of the support rod, which support surface is in the respectively aligned position or in the adjacent position the rail or the centerpiece cooperates with the thrust support of the rail or the centerpiece.
  • a support rod with thrust supports Due to the fact that a support rod with thrust supports is used, a simple drive for the changeover device can be achieved even in the case of complicated and long, swiveling components, which can be adapted to the desired course of the track over the entire length of the respectively adjustable area.
  • the use of support rods with thrust supports allows not only the changeover but also the support of the respective end position of the movement of the movable rail parts in the crossing area and such a design enables a significant improvement in the mounting of pivotable parts in the crossing area of a switch.
  • frogs can be used in a wide variety of training courses in railway superstructure.
  • block cast frogs are known which can be pivotally fixed in a simple manner and can be supported in both directions in the respective pivot position with such a changeover device.
  • the advantage can additionally be achieved that one of the two connecting rails to the heart piece with the heart piece, namely the main tip, can be welded, thereby avoiding an additional interruption in the driving edge.
  • the exact adjustment which is made possible by thrust supports, enables the necessary distance for the passage of the wheel flange to be reliably maintained when pivoting such frogs.
  • temperature fluctuations have no significant influence on the exactness of the selected setting, since long bars are naturally subject to a greater change in length in the event of temperature fluctuations than small-sized thrust supports.
  • the formation of an area which is essentially parallel to the respective direction of travel ensures effective locking of the respectively selected changeover position.
  • the changeover device according to the invention can be used in connection with movable rails in the area of intersection, for which the design is preferably such that the movable rail in the area of intersection is formed by a pivotably mounted piece of rail, the pivot axis of which is essentially normal to the longitudinal axis of the rail between the Free ends of the rail piece is arranged, with thrust supports for pivoting and securing the end position of the rail piece are arranged on both sides of the pivot axis and the rail piece.
  • these thrust supports in addition to the wedge surfaces for the pivoting of the rail section, have support surfaces which are essentially parallel to the longitudinal direction of the rail, it is possible to drive through such crossing areas at increased speed without the need for larger components in the crossing area of the switch.
  • the safe support in the respective swivel position and the possibility of adapting the length of the rail area to be moved or swiveled to the requirements enable the formation of rail switches for the highest speeds.
  • the training can be advantageously made so that at an intersection formed by a rail section that can be pivoted about a pivot axis, inclined surfaces of the thrust supports opposite to each other are arranged on both sides of the pivot axis, so that a safe adjustment of the rail section is ensured with small drives of low power .
  • the changeover device can also be used in a simple manner for frogs which are pivotably mounted about a pivot axis, since here too the securing and support of the frog tip in both directions and thus the maintenance of the required minimum distances of the lifted rail sections is ensured in a particularly simple manner.
  • the changeover device with support rods and thrust supports also enables other, novel designs in the crossover area of a switch, with which the driving comfort and the ability to drive at high speed can be safely maintained even when signs of wear begin to appear.
  • the training for this is advantageous met that the frog tip is slidably mounted in the longitudinal direction of the rail and is resiliently held in contact with a rigid wing rail or connecting rail, and that the thrust supports for the conversion of the frog across the line of action of the spring, the end of the frog tip opposite the resilient system in contact with the Hold the respective connecting rail or wing rail in the direction of travel.
  • thrust supports are arranged on both sides of a support rod, the support surfaces of which are essentially parallel to the longitudinal direction of the support rod and are arranged offset in the longitudinal direction of the support rod.
  • the design can be such that the thrust supports connected to a support rod have cranked strips which extend transversely to the longitudinal axis of the support rod, the flanks of which, facing and facing away from the thrust support, each having at least one counter stop, in particular a roller, the thrust support interact pivotable rail or the movable heart.
  • the design can be advantageously made in a manner known per se such that the thrust supports engage coupling members of mutually associated movable rails.
  • the design according to the invention can be such that movable wing rails and movable connecting rails are connected to a stationary centerpiece which is essentially parallelogram-shaped in plan view, the end faces of which are adjacent to the centerpiece and which are essentially attached to the centerpiece in the respective contact position are designed to run parallel to the adjacent edge of the frog, with a connecting rail and wing rail aligned in the longitudinal direction in each case alternately pressed against thrust supports in abutment against the frog and the other wing rail and the connecting rail essentially in alignment therewith while maintaining a predetermined distance for the passage of the Wheel rim are secured in the respective position by thrust supports.
  • support rods also offers the advantage that exact position monitoring can be carried out, for which limit switches or inductive or capacitive proximity switches can be connected in a known and conventional manner with support rods of this type. Due to the relatively large displacement path of such support rods relative to the relatively small adjustment path that is to be achieved with the changeover device, this results in great precision in the detection of the desired end position, taking into account the areas of the rail which are essentially parallel to the longitudinal direction of the rail Thrust supports also signal the safety of the support.
