Definitions

  • the technical solution concerns the frog, mainly for switches of town transport rails.
  • the hitherto known and used frogs for town transport are simple frogs welded of facing rail casts and slot profile rails of standard quality.
  • the weldment is further welded to the stringer metal plate and side and front metal sheets are welded so as to reach compact unit of the frog.
  • Shallow grooves are made in the frog to safely cover the switch diamond and to arrange fluent and smooth passage.
  • the frog with enclosed rails is usually a part of the switch weldment on the route.
  • frogs are simple frogs performed as a weldment of a steel block with machined grooves and four facing rails. The frog is usually welded into the route. Wear and tear of the frog material in the field of switch diamond and crossing caused by traffic is repaired to a specific operation status by using the welding-on technology. In case of excessive wear and tear it is necessary to open the ballast and to replace the frog, which is very time- and money-consuming.
  • EP-A-143 289 shows a frog representing the closest prior art and showing the features of the preamble of claim 1.
  • the task of the technical solution is to eliminate to the maximal possible extent the imperfections of known versions of frogs as well as to create a frog of simple construction allowing easy replacement of their worn-down parts without opening the rail parts.
  • the external and internal parts are connected on detachable basis using inserts flushed in gaps between the sides of the external part and longitudinal grooves on sides of the internal part, while the inserts are equipped with holes for screws with their nuts placed in shaped grooves made in the external part recession bottom and continuing the assemblage holes leading out of the external part.
  • the gap and the insert are wedge-shaped for reliable securing of the internal part.
  • At least one internal part is purposeful - in consideration of resistance - for at least one internal part to be made of abrasion-resistant steel, mainly bainitic steel.
  • FIG.1 schematically shows the view of the frog
  • Fig.2 shows the detail of internal and external part of the frog
  • Fig.3 shows a detail of the external part of the frog with removed internal part.
  • the frog includes a bigger part, connected with connection rails 2 .
  • the recession 3 made in the external part 1 houses a push-placed internal part 4 with crossing 5 .
  • the fronts 6 of the internal part 4 to be of wedge shaped form with matching treated recession fronts 7 of the recession 3 .
  • the internal part 4 with crossing 5 is connected on detachable basis with the external part 1 using the inserts 8 , arranging side settings of the internal part 4 .
  • the inserts 8 are recessed into gaps 9 between side walls 10 of the external part 1 a longitudinal grooves 11 on side walls 12 of the internal part 4 .
  • Inserts 8 are equipped with holes 13 for screws 14 , with their nuts 15 inserted in shaped grooves 16 made in the bottom 17 of the recession 3 of the external part 1 , while the shaped grooves 16 house - from the outer side of the external part 1 - the assemblage holes 18 , ideally of round shape for round-shaped nuts.
  • the assemblage holes 18 lead from the outer side of the external part 1 to shaped grooves 16 ._
  • the gap For better settlement of the internal part 4 it is suitable for the gap to be wedge-shapes for wedge-shaped inserts 8 .
  • the material for external and internal parts 1 , 4 should be abrasion-resistant, for example bainitic steel. So as to make dismantling easier, the inserts 8 and the internal part 4 house threaded holes 19 . In consideration of possible pollution it is suitable for the assemblage holes 18 and threaded holes 19 to be blinded by covers not shown in the example.
  • the internal part 4 is inserted to the recession 3 of the external part 1 , through assemblage holes 18 there are inserted the inserts 8 and screws 14 to shaped grooves 16 and to the gap 9 - they pass up to the inserts 8 and they are screwed to nuts 15 and tightened, which means that the position of the internal part 4 is secured.
  • the frog can be favourably used in switches of town tram transport.
