Definitions

  • ABSTRACT This invention relates to a tongue device with pivotal connecting rails for switch points which can be negotiated at high speeds free from vibrations and jolts in the branching track comprising base means, connecting rails of a main track and a branching-off track hingedly connected with each other and pivotally mounted on said base, means for pivoting said connecting rails, and wedge means adapted to be insertedtin corresponding recesses in mutually adjoining tracks for closing the gaps in the two extensions of the inner rail edges.
  • the present invention relates to a tongue device with pivotal connecting rails for switch points which can be traveled on or negotiated at the highest'speeds and under great traffic loads in the branching-off track without vibrations and jolts.
  • the present invention is based on the goal and object of changing or switching the connecting rails provided as tongues in a manner such that, after the changing or switching operations, they will be either uniformly bent or straight, and of assuring that after the completed change-over or switching operation the ends of the tongues and of the continuing tracks of the main or primary rail cannot move relative to each other under the traffic load, and that continuous running rail edges will be produced in the gap area.
  • connecting rails of the main or primary rail and of the branching rail are hingedly connected with each other in the front area or portion thereof and are pivotally positioned by means of control members on glide chairs with respect to the tongue device entrance of the main or primary rail, in that they are mounted on a continuous base plate and adapted to be locked in a respective end position thereof, and in that the gaps between the ends of the connecting rails and the main or primary rail tracks are closable in the two extensions of the inner or running edge of the rail by means of wedges which may be inserted in corresponding recesses of the mutually adjacent rails.
  • the ends of the connecting rails being provided as tongues, after having assumed the respective end positions thereof, are braced on the base plate relative to the ends of the main or primary rail, preferably with the aid of mechanical, electrical, hydraulic, or pneumatically-driven clamping devices, so as to prevent relative movement of the rail ends on both sides of the gap under a traffic load.
  • the ends of the connecting rails as well as the ends of the main or primary rail are made, depending upon the stress thereon, preferably from a high-strength, martensitically-hardened, ductile nickel steel and welded to the corresponding rails. In this manner, room is provided for the specifically constructed guides which maintain the wedges in the vertical and horizontal directions.
  • the wedges preferably should be so constructed that in a top plan view thereof they have a trapezoidal contour, and that the apices as well as the obtuse ends of the wedges are lowered slightly as compared to the tread of the rails.
  • the end position of the wedges is adjustable for purposes of the setting and/or for taking into account the subsequent wear and tear.
  • the wedges are locked in the end position thereof by means of an electrically, or pneumaticallyor hydraulically-driven locking or clamping mechanism.
  • the gliding surfaces of the wedges and/or the guides are coated with a maintenance-free, friction-reducing, elastically-acting plastic layer such as perfluoroethylene.
  • control relative to the movement of the wedges and relative to the bracing or clamping of the movable connecting rails in the respective end position thereof is coupled to or linked with the change-over or switching device of the connecting rails and any possibly existing movable parts of the frog, preferably electronically.
  • FIG. 1 is a top plan view of the tongue device of the present invention
  • FIG. 2 is a cross-sectional view through the left half of the tongue device taken on line A--A of FIG. 1.
  • the entire tongue device has been shown in FIG. 1 at a distorted scale for reasons pertaining to space. In reality, the tongue'device designed for highest speeds is considerably longer because of the required great radius of the branching rail. 7
  • the tongue device consists of the continuous base 1 upon which the connecting rails 2 to 5, which are constructed as tongues and are hingedly connected with each other in the front zone or portion thereof are pivotally positioned.
  • the tracks of the main or primary rail 6 and 7 are rigidly mounted on the base plate 1.
  • the ends 8 to 11 of the connecting rails 2 to 5 as well as the ends 12 and 13 of the tracks 6 and 7 of the main or primary rail are preferably made from high-strength solid materialand are welded to the corresponding rails 2 to 7.
  • the connecting rails 2 to 5 constructed as tongues are moved with the aid of several mechanically, electrically, hydraulically, or pneumatically-driven control members 14 to 17.
  • the wedges and 21, whose apices 22 and 23 and obtuse ends 24 and 25 are slightly lowered as compared to the surrounding traveling'surface, are inserted in the recesses 26'and 27 and 28 and 29 respectively, preferably with theaid of pneumatic cylinders
  • the guides 30 and 31 and 32 and 33 respectively, at the ends of the connecting rails 8 and 9 have been illustrated in FIG. 2 for the horizontal and vertical position determination of the wedge 20.
  • a device in which the ends of the rails are made from high-strength, martensitically-hardened, ductile nickel steel and are welded to the rails.
  • a device in which the wedge means have a trapezoidal configuration in top plan view and the apices and obtuse ends thereof are slightly lower than the adjacent traveling surface.
  • a device in which the wedge means are adapted to be locked in the end position thereof.
  • a device in which the sliding surfaces of the wedge means are coated with a frictionreducing, elastically-acting plastic coating.
