Definitions

  • the invention relates to a device for support the sliding movement and for the elastic locking of movable Turnout parts, especially turnout tongues of Rili rail turnouts, with an axially movable pipe or Rod, which has recesses for the Includes receiving radially displaceable locking members and one concentrically surrounding the pipe or rod Pipe, which has recesses for receiving radially outwards has displaced locking members.
  • a changeover aid are also from AT-PS 379 624 already known, with a spring rocker used came at an angle lever at the crossing point of the arms is mounted, an energy accumulator by means of a compression spring is supported against the arms of the two angle levers.
  • Two spring rockers were here over a coupling rod with the two tongue rails connected.
  • the invention now aims to set up a device mentioned type to the extent that they are particularly compact and can be trained short and both at Rail switch adjustment drives as well as a conversion aid for Turnouts can be used.
  • the compact training should the subsequent retrofitting of existing switches in a simple way Allow wise and especially for grooved rail switches be suitable.
  • the training according to the invention consists essentially in that the locking members in two separate at an axial distance from each other between the tube and pipe sections or cages arranged on the rod are stored, and that between the pipe sections or cages one in axial Direction acting compression spring is arranged. Because now two separate pipe sections or Ball cages are arranged, the arrangement of a single is sufficient Compression spring between these pipe sections in order at appropriate Arrangement of the recesses for the locking members resilient support of the changeover movement as well as a resilient Ensure that the end position is locked. Overall, the entire arrangement in a single fixed outer tube locked on the outside and thus against ingress of dirt be trained so that operational safety without maintenance guaranteed over a long service life.
  • the training is such that the axial distance of the recesses for the locking members in Pipe different from the axial distance of the recesses on the Rod is selected.
  • the outer tube is advantageously arranged stationary, the rod as the switch tongues in a particularly simple manner connecting coupling rod can be formed.
  • a such coupling rod connecting the switch tongues can directly be connected to a drive, so that instead of existing operating rod of the point machine simply the Device according to the invention used directly as a drive rod can be. With regard to the compact dimensions existing coupling rods can be replaced without any structural Changes.
  • the inventive design is particularly advantageous made so that the recesses for the locking members as circumferential or ring grooves and the locking members are designed as balls.
  • the bearing construction known to be designed as ball cages, so that a particularly simple training is made possible.
  • the training is advantageously made so that the annular grooves have a trapezoidal cross section.
  • the closed design according to the invention and the compact Training can also be an additional hydraulic Damping and thus a reduction in noise during the changeover process realize in a simple way. It is an advantage here the training taken so that the cages for the locking members are sealingly guided between the rod and tube, and that the annular space containing the compression spring opens outwards Check valves and one parallel to each of these valves switched throttle with those located outside the spring chamber Annular spaces is connected. With such training the final phase of the changeover movement is hydraulically damped, whereby the fluid from the outer annular space into the spring space is pressed back. With appropriate dimensioning of the cross sections can do this with complete filling of the annular spaces Fluid can be ensured.
  • the shifting movement can be used be ensured that the spring in the first part of the displacement movement can be further compressed to subsequently under partial relaxation the stored spring force as a changeover aid again to provide. It is therefore advantageous the training so that the compression spring in one End position of the device corresponding position partially relaxed is.
  • the compression spring can be used as Coil spring be formed.
  • FIG. 1 shows a view of the adjustment device according to the invention partly in section with the point machine
  • Fig. 2 a plan view of the changeover in the direction of arrow II
  • 3 shows an enlarged view of the invention Device in a first left end position
  • Fig.4 a Representation analogous to Figure 3 in a transition position during the Switching movement
  • Fig.5 the beginning of the relaxation of the compression spring to support the changeover movement to the right
  • Fig. 6 the right end position of the device according to the invention and FIG schematic representation of an additional hydraulic damping in a training according to Figures 3 to 6.
  • a grooved rail switch can be seen, the movable switch tongues with 1 and the stock rails with 2 are.
  • the switch tongues 1 are with coupling pins 3 a rod 4 coupled, which itself by a schematic indicated drive 5 in the direction of the double arrow 6 is.
  • the device according to the invention is shown schematically at 7 to support the sliding movement and for elastic Lock the tongue rails 1 shown, which in the the following Fig. 3 to 7 is clarified.
  • the rod 4 has on her Scope in cross-section trapezoidal grooves 10 and 11, the axial distance with b is selected.
  • ball cages 12 and 13 are the locking members 14 and 15 formed as balls arranged.
  • the fixed outer tube 16 has grooves 17, the effective axial distance of these grooves 17 from each other is selected differently from the distance b.
  • the rod 4 succeeds in the right end position in which the resilient system the right tongue under the action of the compression spring 18 guaranteed is.
  • the locking members 14 are here in their outer position in the recesses 17 of the fixed tube 16th added, whereas the locking members 15 in their radially inwardly shifted position in the groove 11 of the rod are so that the rod over the locking members 15th by the force of the spring 18 in the direction of arrow 19 right is pressed.
