Definitions

  • the invention relates to an arrangement for holding down a frog tip which runs between wing rails and can be supported on a base such as a sliding chair, in particular a movable and spring-movable frog tip of a frog of a switch or crossing.
  • the frog tip or the frog block is supported between wing rails on a base such as a sliding chair, whereas the wing rails largely originate from documents such as rib plates.
  • a base such as a sliding chair
  • wing rails largely originate from documents such as rib plates.
  • a linkage starts from a centerpiece for grooved rail switches, which passes through wing rails and via which the centerpiece is adjustable.
  • DE-AS 1 272 951 describes a pivotable centerpiece which is adjustable via a linkage running below wing rails.
  • WO 94/19542 and DE 43 05 228 A1 have disclosed a spring-movable centerpiece tip which starts from a driver device which is supported on the underside of the wing rails, so that a quasi-rigid unit is formed.
  • the driver device which is supported indirectly via plate springs relative to the centerpiece tip, is lifted off the wing rails.
  • the present invention is based on the problem of developing an arrangement for holding down a frog tip of the type described in the introduction in such a way that it is ensured that the frog tip is held down securely with structurally simple measures, while at the same time ensuring that the frog tip is adjusted from one wing rail to another Wing rail a desired smoothness is given without having to move additional masses next to the centerpiece tip.
  • the problem is essentially solved in that the frog tip is penetrated by an element which is subjected to force in order to hold the frog tip down in the direction of the support, and that the element in is adjusted to adjust the frog tip an opening penetrated by it can be raised or rotated in the centerpiece tip in such a way that it can be adjusted to the desired extent.
  • the element passes through both the frog tip and the wing rails, the element starting from a holder which extends in sections below the wing rails and which is supported on the underside via at least one spring element on at least one wing rail foot.
  • the holder can be adjusted upwards, that is to say in the direction of the wing rail head.
  • the element itself is preferably rod-shaped and has, in the adjustment path of the frog tip in the direction of the base, protruding sections such as cams, one of which is supported when the frog tip is held down in its position in contact with one of the wing rails in the bottom region of the opening. This ensures that the tip of the centerpiece is held down securely without the element having to be supported flatly in the opening.
  • the holder comprises a plate-shaped section which extends below the wing rails and which is supported on the underside on the wing rail feet via spring elements such as plate springs.
  • the unit acts on the plate-shaped section of the holder like a piston-cylinder arrangement in order to be able to adjust the plate-shaped section against the force caused by the spring elements, as a result of which the spring elements are pressed together.
  • a piston-cylinder arrangement it is of course also possible to use another unit, such as a servomotor, or to move it by means of a magnet.
  • the holder itself extends on the outside along the wing rails and has clamping jaws for gripping the rod-shaped element. Furthermore, the holder has a clear distance in the region of the rail feet of the wing rails which is greater than the distance between the outer edges of the wing rail feet. This ensures that the Wing rail feet do not hinder the up and down movement of the bracket.
  • the unit itself which adjusts the holder against the force caused by the spring elements, can start from a holder which is indirectly or directly connected to the wing rails. So the bracket can start from a ribbed plate or from supports of the wing rails such as sleepers.
  • the bracket is preferably fixed to the wing rail feet via clamping jaws.
  • rod-shaped element has projections such as cams, which force the centerpiece tip in the direction of the support by rotating the element or to which the centerpiece tip is adjustable.
  • the figures show sections through a centerpiece tip 10.
  • the centerpiece tip usually comprises a movable centerpiece block 12 which runs between wing rails 14 and 16.
  • the frog block or frog tip 12 is supported on a sliding chair 18 which, in the exemplary embodiment, is used as inner rail bracing for the wing rails 14 and 16 is formed.
  • the wing rails 14 and 16 themselves are supported on documents, not shown, such as rib plates, which in turn are arranged on supports such as sleepers. In this respect, however, reference is made to well-known track superstructures.
  • a preferably rod-shaped element is provided, which both the frog tip 12 and the Wing rails 14, 16 penetrated in openings 22, 24 and 26.
  • the openings 22, 24 and 26 are aligned with one another.
  • the rod element 22 is based on a holder 28 which, in the exemplary embodiment, comprises outer clamping jaws 30, 32, via which the rod element 20 is clamped, and a plate-shaped section running beneath the wing rails 14 and 16 as the base plate 34.
  • the holder consequently has a U-geometry comprising the wing rails 14, 16 in section.
  • spacers 36, 38 are also provided, the clearance between them being greater than the distance between outer edges 40, 42 of the wing rail feet 44, 46 is. This measure is intended to ensure that friction between the holder 28 and the wing rail feet 44, 46 is excluded.
  • clamping jaws 30, 32, the spacers or intermediate plates 36, 38 and the base plate 34 are connected or clamped to one another via bolts or screws 48, 50.
  • the base plate 34 of the holder 28 extends at a distance from the underside of the feet 44, 46 of the wing rails 14 and 16. Furthermore, the base plate 34 and thus the holder 28 are supported with respect to the wing rails 14 and 16 by spring elements such as plate springs 52, 54. As a result, the holder 28 or the rod element 20 is pulled downwards, that is to say in the direction of the sliding chair 18 or the feet 44, 46 of the wing rails 14, 16. As a result, the rod element 20 is supported on the bottom area of the opening 22 of the frog tip 12, so that the frog tip 12 is held down on the sliding chair 18. In contrast, the rod element 20 passes through the opening 24, 26 of the wing rails 14, 16 spaced.
  • the rod element 20 has projections, such as cams 56, 58, which extend in the direction of the sliding chair 18 and are then supported on the bottom of the opening 22 of the frog tip 12 when the frog tip 12 on the wing rail 14 or rests on the wing rail 16.
  • the holder 28 can be raised to such an extent that the rod element 20 passes through the opening 22 of the frog tip 12 largely spaced apart due to the construction according to the invention.
  • a force is let into the base plate 34, by means of which the plate springs 52 and 54 are pressed together.
  • an adjustment unit in the form of a cylinder-piston arrangement is based on a holder 60, the piston 64 engaging via a resilient intermediate layer 66 in a bottom-side recess 68 from the base plate 34.
  • the base plate 34 is consequently raised against the spring force, as a result of which the rod element 22 is raised and the centerpiece tip 12 can thus be easily moved from the wing rail 14 to the wing rail 16 or vice versa.
  • the rod element 20 Regardless of the position of the rod element 20, that is, regardless of whether the force acting on the bracket 28 is solely the force of the plate springs 52 or the force directed against it and caused by the drive unit 62, the rod element 20 penetrates the openings 24, 26 of the wing rails 14, 16 always with play.
  • the bracket 60 for the drive unit 62 starts from the wing rail feet 44, 46, as shown in FIG. 2.
  • a receptacle of the holder 60 in which the unit 62 is fixed, is connected to the wing rail feet 44, 46 via clamping jaws 72, 74.
  • a plate 76 runs between the underside of the rail feet 44, 46 and the receptacle 70.
