Definitions

  • the invention relates to a heart of a switch, for connection to connecting rails, with a block-like body and with a particular resiliently movable, two point pieces having frog point.
  • Both rule wing rails having frogs and frogs with block-like bodies are anchored at their installation in the ground, so that the forces acting on the core during driving forces can be introduced into the ground.
  • Object of the present invention is therefore to provide a heart of the type mentioned, in which the aforementioned disadvantages do not occur.
  • the base body has at least one terminal block with an outer terminal portion for connection of a terminal rail and an inner terminal portion for connection of a tip piece and that provided between the outer terminal portion and the inner terminal portion a trailing edge region on the terminal block is, so that there is a spatial decoupling of the connecting rail of the tip piece.
  • the base body in such a way that a bottom plate is provided on which both wing rail sections and the corresponding terminal blocks for connection to the connecting rails on the one hand and the point pieces on the other hand are provided.
  • This may be, for example, a welded construction.
  • a block-like design it is particularly advantageous, however, to produce the basic body in one piece by machining or casting. It is then a so-called monoblock, in which the tip pieces are then arranged and at the same time the arranged between the respective tip pieces and the connecting bars terminal blocks are provided.
  • the training as a so-called monoblock also includes that the body fundamentally processed from several accordingly Components can be assembled, which have been produced by abrasive machining or casting.
  • the main body as a monoblock allows the formation of the main body as a monoblock to provide in this one in plan view V-shaped receptacle for the tip pieces.
  • the depth of the shot then corresponds at least to the height of the tip pieces.
  • the tip pieces are otherwise also laterally, namely protected on both sides.
  • it allows the formation of the body as a monoblock readily to provide in the body heating chambers and / or water drainage just in view of the self-contained V-shaped receptacle to avoid weather-related problems (icing) when placing the frog point.
  • the construction according to the invention allows, moreover, in a very simple manner to exchange the tip pieces. It is particularly advantageous in this context that the tip pieces are each mechanically detachably connected to the inner terminal region, in particular screwed.
  • the tip pieces each have a correspondingly machined oblique or S-shaped fastening region with screw openings, in order to be screwed to the correspondingly processed inner connection regions of the connection blocks.
  • This type of formation of the attachment area not only ensures a good transition from the tip pieces to the respective terminal blocks, it can also realize a quick exchange of worn tip pieces by new.
  • the screw holes should be accessible from the outside at the base block in order to be able to carry out the replacement in a simple manner.
  • the expansion joint between the two tip pieces at the front end and the front tip of the frog tip is provided.
  • the expansion joint which is required to realize the relative movement of the two top parts to each other when setting the frog point, is moved all the way forward to the frog point.
  • the expansion joint should be formed as a continuous rectilinear, leading through the front end gap between the tip pieces.
  • Such a configuration can be realized easily by appropriate milling.
  • this also results in that both tip pieces have the same length, which is not the case in the prior art with resiliently movable tip pieces.
  • the coupling between the two point pieces is advantageously carried out via a positive engagement in the vertical direction, which simultaneously allows movement of the tip pieces in the horizontal direction, which is required when adjusting the frog point.
  • the aforementioned positive connection can be formed by a tongue and groove connection, wherein at the end region of a tip piece a groove is provided, while at the end region of the other tip piece a spring corresponding thereto is provided.
  • the groove and the spring can be easily produced by abrading the front end portion of the tip pieces.
  • the tip pieces are each made of tongue rail profiles.
  • tongue and groove rail profiles in particular manganese tongue rails
  • the spring points or the spring-moving areas are provided on the arranged in the base body tip pieces.
  • the connection points to the connecting rails are outside the spring-moving region of the tip pieces.
  • rule tongue rails are characterized by a reduced weight compared to the custom-made tip pieces, so that correspondingly lower actuating forces and correspondingly smaller-sized drives are required. Furthermore, when using rule tongue rail profiles, the tip pieces can be made relatively long.
  • FIGS. 1 to 4 show a frog 1 of a switch not shown in detail.
  • the heart 1 is for connection to connecting rails, which are not shown in detail, provided. In the illustrated embodiment, the connecting rails would connect to the right of the heart piece 1.
  • the centerpiece 1 has a block-like basic body 2. Furthermore, it is provided with a frog point 3, which in turn has two point pieces 4, 5.
  • the tip pieces 4, 5 are spring-movable tip pieces, wherein the actuator for the frog point 3 is not shown.
  • the adjusting device acts on the front end region 6 of the frog tip 3 or its tip pieces 4, 5 via corresponding linkages, which are connected to the front end portion 6 of the frog tip 3.
  • the base body 2 is formed such that it has outside wing rail sections 7, 8, which are integral with the base body 2.
  • the wing rail sections 7, 8 each have a recess 10, 11 with a final step 12, 13, wherein the respective recess 10, 11 is provided for receiving the front end of the frog point 3, to a substantially flat and continuous transition of the running edge of the respective wing rail to achieve the frog point 3.
  • each terminal block 14, 15 which serves to connect the respective terminal rail on the one hand and the respective tip piece 4, 5 on the other.
  • Each of the terminal blocks 14, 15 is formed integrally with the main body 2.
  • Each of the terminal blocks 14, 15 has, moreover, an outer terminal region 16 for connecting the respective terminal rail and an inner terminal region 17 for connecting the respective tip piece 4, 5. It is important present that between the outer terminal portion 16 and the inner terminal portion 17, a trailing edge portion 18, that is, a block portion with an outer trailing edge portion, is provided on the respective terminal block 14, 15, so that a decoupling of the respective terminal rail of the respective tip piece 4th , 5 results.
  • the block-type basic body 2 is therefore a so-called neutralization frame, via which the forces introduced by the connecting bars are discharged into the substrate and thus do not act directly on the frog tip.
  • the base body 2 is made in one piece by removing machining (milling) or casting. It is in the present case a one-piece component, but this does not have to be so fundamentally.
  • a V-shaped receptacle 19 in which the tip pieces 4, 5 are inserted.
  • the receptacle 19 is substantially closed down and on both sides. Excluded from this is only a water discharge, not shown in detail. Otherwise points the main body 2, which is also not shown, on heating chambers to ensure the mobility of the frog tip 3, even at low temperatures.
  • the tip pieces 4, 5 respectively mechanically detachably connected to the inner terminal portion 17, namely are screwed.
  • the tip pieces 4, 5 each end a machined S-shaped mounting portion 20 with screw holes 21.
  • the inner terminal portion 17 of the respective terminal block 14, 15 is adapted from the outer shape to the S-shaped mounting portion 20 of the tip pieces 4, 5.
  • screw openings 22 are provided, via which the screw can be done.
  • the expansion joint 23 is a continuous rectilinear, leading through the front end 24 joint between the tip pieces 4, 5.
  • the two tip pieces 4, 5 have the same length otherwise.
  • an effective positive connection in the vertical direction is provided, which allows a movement of the tip pieces 4, 5 in the horizontal direction, which occurs when the frog point 3.
  • this is realized by a spring-groove connection 25, as shown in Fig. 11.
  • the front end portion 26 of the one tip piece has a spring 27 in the manner of a projection which engages in a groove 28 in the front end portion 26 of the other tip piece. Both the spring 27 and the groove 28 have been made by abrasive machining of the tongue rail profile.
  • the tip pieces 4, 5 have each been made of tongue rail profiles, namely standardized rule tongue rail profiles, in particular of manganese tongue rails, by abrasive machining.
  • Tongue rail profiles which are at least partially machined on the end and from which ultimately the tip pieces 4, 5 are made are shown in FIGS. 5 to 8.
  • the front end region 26 on the one side with the groove 28 has already been processed. Further processed is both the mounting portion 20 with the screw holes 21. Still milled is the one flank 29 of the rail foot of the tongue rail profile and the opposite edge 30.
  • the flanks 29, 30 in the installed state of the tip pieces 4, 5 no longer available.
  • FIGS. 7 to 10 show a preliminary stage of the tip pieces shown in FIGS. 5 and 6, wherein the fastening region 20 has not yet been provided. For the rest, results from a comparison of FIGS. 7 and 8, the actual Tongue rail profile from which the top parts 4, 5 are made.
