Definitions

  • the present invention relates to a deflecting device with gaps locked in a wedge-type manner which can be negotiated at the highest speeds and with great axle loads and yet free from vertically acting and horizontally acting vibrations and shocks.
  • deflecting devices which are intended to have a large radius in the branched track to provide the two rails of the tracks as tongues in the zone or area of the entrance. These are changed over corresponding to the desired traveling direction.
  • the disadvantage of deflecting devices of this type is that one gap each is open according to the tongue position between the tongue end and the other parts of the switch, in other words, between the continuous rail and straight intermediate rail and, respectively, the bent intermediate rail and the branching-off rail.
  • the present invention changes over the tongues so that, after the change-over operations, they are uniformly bent or straight and assure that after the changeover the ends of the tongue and of the continuing rails cannot move relative to each other under the traffic load, and continuous running edges will be produced in the gap area or zone.
  • the tongues are adapted to be changed over with the aid of if desired several pneumatically, hydraulically, or electrically driven tensioning elements against a continuous longitudinal girder, preferably made from metal.
  • the gaps produced between connecting rails and tongues are provided in the two running edge courses so as to be adapted to be locked by means of specifically shaped wedges inserted in the longitudinal direction.
  • the tongue ends and the I beginning of the adjoining rails are made from solid material and are welded to the corresponding rails. In this manner, space is created for the specifically constructed guides which maintain the wedges in the vertical and the horizontal directions.
  • the bracing of the tongue in the end position thereof is necessary in order to maintain an alignment of the running edge also under the traffic load.
  • the prevention of relative movements of the rail ends on both sides of the gap also may be achieved by virtue of the fact that not only one wedge but a second wedge is inserted per gap, preferably on the side of the rail which is not traveled on.
  • the wedges are so provided that, in a top plan view thereof, they have the form of a triangle.
  • the control for the movement of the wedges is suitably electronically linked to the change-over or switching device of the tongues and possibly with that of any existing movable portions of the frog.
  • the advantage afforded by the present invention resides in that such a construction renders it possible to build deflecting devices for branch rail radii of any desired size, and that these in contrast to the heretofore known deflecting devices therefore may be traveled on or negotiated free from shocks and vibrations at very high speeds also in the branch rail.
  • FIG. 1 is a top plan view of the deflecting device of the present invention
  • FIG. 2 is a top'plan view of the left half of the deflecting device of the present invention in the position branch rail;
  • FIG. 3 is a top plan view of the left half of the deflecting device, but in the position main rail;
  • FIG. 4 is a side view of the left half of the deflecting device (FIG. 2)
  • FIG. 5 is a cross-sectional view through the left half of the deflecting device, taken along line A-A, with the tongue position according to FIG. 3.
  • the entire deflecting device has been illustrated in FIG. 1 in a distorted scale for reasons of economy of space. In reality, the deflecting device for highest speeds is considerably longer because of the required large radius of the branch rail.
  • FIGS. 2 to 4 The pneumatic cylinders serving for changing over the tongues, and shown by way of example in FIG. 1, have been omitted from FIGS. 2 to 4 in the interest of a clearer representation of the details.
  • the deflecting device of the invention consists of the track rails l and 2, the tongues 3 and 4, as well as of the connecting rails 5 to 8.
  • the track rails 1 and 2 as well as the connecting rails 5 to 8 are rigidly connected with the continuous base plate 9 with the aid of known rail attaching means, whereas the tongues 3 and 4 are movably positioned.
  • the spring points 10 and 11 of the tongues 3 and 4 facilitate the horizontal movement particularly of short tongues.
  • the tongue ends 12 and 13 and the rail ends l4, l5, l6 and 17 preferably are made from high-strength solid material and welded to the tongues 3 and 4 and, respectively, to the rails 5 to 8.
  • the tongues 3 and 4 are switched over in accordance with the desired radius and with the aid of several mechanical, electrical or hydraulic thrust positioning drive means, in this case for example by way of the pneumatic cylinders 18 to 27.
  • the wedges 32 to 35 are inserted into .the recesses 36 and 37 of the tongue ends 12 and 13, preferably with the aid of the pneumatic cylinders 38 to 41.
  • the guides 42 and 43 and, respectively, 44 and 45 in the tongue end 12 and, respectively, in the end 15 of the connecting rail 6 for the horizontal and vertical position determination of the wedges 32 and 33 have been illustrated in FIGS. 4 and S.
  • a deflecting device for switches which can be negotiated at high speeds free from vibrations and shocks in the branch rail comprising movable tongue means which are sections of the main rails, the free ends of said tongue means having recesses therein extending in the longitudinal direction of the rails, wedge means adapted to be inserted into said recesses in order to close the gaps between said tongue means and connect ing rails, and means for moving said wedge means into and out of the closed position.
  • a deflecting device according to claim 1 in which the means for switching the tongue means are mounted between the ends of the deflecting device.
  • a deflecting device in which the means for switching are double-acting cylinders.
  • a deflecting device in which the means for moving the wedge means are doubleacting cylinders.
  • a deflecting device in which the .wedge means have a triangular shape in top plan view.
  • a deflecting device including inclined guide path means for said wedge means, whereby automatic locking is effected.
  • a deflecting device according to claim 1 in which the end position of the wedge means is variable, for setting purposes and for compensating for wear and tear.
  • a deflecting device in which the sliding surfaces of the wedge means are covered with a friction-reducing coating.
  • a deflecting device according to claim 8 in which the coating is perfluoroethylene.
  • a deflecting device in which the wedge means are fabricated from a high-strength martensite-hardened ductile nickel steel.
