Definitions

  • the invention relates to a grooved rail frog comprising an intersecting one Groove formed heart intersection area such as wheel overflow area, the heart comprises two longitudinally extending construction profiles, which in the center intersection area are welded in the longitudinal direction of the heart. Also, the refers The invention relates to a method for producing a grooved rail frog comprising by intersecting grooves formed heart intersection area such as wheel overflow area, the centerpiece comprising two construction profiles extending in its longitudinal direction, which are welded in the center section point area in the longitudinal direction of the heart.
  • Known grooved rail frogs consist of a heart block, at the end faces Connecting rails are welded. In the block itself, cutting grooves become Training a Radüberlauf Symposiumes worked out, usually in the connecting rails pass.
  • US-A 1 878 984 relates to a grooved rail frog, the frog having two in whose longitudinal direction comprises construction profiles in the form of grooved rails.
  • the frog intersection region is formed as a separate element. Below the centerpiece midpoint area the grooved rails are welded, but the rail heads are bent.
  • FR-A-2 396 833 proposes a grooved rail frog with a separate insert.
  • US-A-5 820 702 relates to welded rails to form a rail Centerpiece with head and tip.
  • the present invention is based on the problem, a grooved rail frog or a Process for the preparation of such a way that this with structurally simple Measures is provided and also over a long distance from the intersection of Grooved from viewed in the longitudinal direction shows a homogeneous material course. It should be desired Corner piece angle can be easily formed. Furthermore, the possibility should be be created wear-resistant form the wear-intensive Radüberlauf Symposium.
  • the heart-shaped intersection region consists of Sections of two separately manufactured construction profiles, which in the intersection area like Overflow area are welded together. Since the rail frog only one section at a time The interconnected construction profiles can be substantial Distance to the core itself, a connection made with connecting rails. Thus, in the immediate area of the frog does not require a butt fusion with the consequence that results in a homogeneous workpiece course in the longitudinal direction. Because of the state The technique required homogeneous core block is not necessary, the core section even shorter. This results in a short compact Construction, which also allows large frog angle, without the ride comfort of a corresponding heart of passing vehicle is impaired.
  • two symmetrical construction profiles such as thick-web rails
  • the design profiles are in theirs machined facing each other and to be welded together surfaces.
  • the Railheads themselves have weld preparation like joints on the construction profiles connect by joint welding.
  • the welded joint consist of different layers, which optionally have additives.
  • the welding may comprise a cover layer with a filler material which for joint welding, for example, for high-alloyed stainless steels and Mixed connections between these and normal structural steels as well as an order material is common for rails and switch parts.
  • construction profiles can have two or more screw connections be fixed to each other and as a unit formed on a common base plate be arranged and connected to this by normal welding techniques.
  • Other Connection types are also possible.
  • the grooved rail frog consists of two construction profiles 18, 20, which are formed in the initial state as a full head profile.
  • construction profiles For example, thick bars or square profiles are possible without this a limitation of the teaching of the invention takes place.
  • the construction profiles 18, 20 are now so bent and aligned with each other that they take the shape of his Longitudinal axis divided finished core 10 correspond. In their intended joint surfaces the profiles 18, 20 are processed flat. Furthermore, in the respective rail head a Weld preparation in the form of joints 22, 24, 26, 28, which are used for welding Construction profiles 18, 20 are required. Then the construction profiles 18, 20 mutually positively connected by means of screw 34.
  • the can Screw connections Nord-Lock sterommeen have. As far as known Constructions referenced.
  • the construction profiles 18, 20 are then in the longitudinal direction of the core 10 in Essentially connected by joint welding.
  • the corresponding in the joints 22, 24, 26, 28, 30, 32 formed welds are denoted by the reference numerals 38, 40, 42nd provided in the sectional views, the welds themselves already partially processed are, by forming the grooves 12, 14; because only after the welding the construction profiles 18, 20, the grooves 12, 14 are formed in their heads 19, 21, as a result, in the cutting region 44 of the grooves 12, 14, the weld 42 up a floor area is removed, which at the same time the bottom of the wheel overflow area 44th cutting grooves 12, 14 is.
  • the welds can be designed so that the groove areas exposed to a special wear such as the floor in the cutting area 44 or the inner flanks of the grooves 12, 14 in the vicinity of the intersection 44 (Fig. 3) consist of low-wear material.
  • a special wear such as the floor in the cutting area 44 or the inner flanks of the grooves 12, 14 in the vicinity of the intersection 44 (Fig. 3) consist of low-wear material.
  • Welding consumables with wear-reducing properties used for example, for high-alloy stainless steels and mixed compounds between these and normal structural steels or as contract materials for rails and Turnout parts are used.
  • weld the welds 38, 40 through layers, so-called root and form filling layers and cover layers, wherein the root and filling layers connecting additives and the cover layer, which interact with a wheel passing through the core 10, be provided with order additions.
  • the teaching of the invention is in the immediate vicinity of the intersecting grooves 12, 14 a butt weld not necessary. Rather, the training of the Centerpiece 10 welded in the longitudinal direction of construction profiles, which in the initial state show a full head profile.
  • the teaching of the invention allows the preparation of frogs z. B. with small heart angle between, for example, 0 ° - 40 ° and / or Flachrillen Suiteen desired length, on which the wheel flange of a wheel can roll.
