Definitions

  • the invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 5.
  • a generic device is off EP 1 375 749 A2 known.
  • the rail driving surface In the transition region from a heart to a subsequent, slightly higher rail track, it is necessary to form the rail driving surface as a ramp. This must be as even and smooth as possible in order to keep the vertical acceleration forces when driving a wheel tread on the core low and thus reduce material wear and subsequently to maximize cost savings. In the course of repair work, the surface geometry of the rails, in particular the core, must be restored as precisely as possible. However, the quality of such a ramp produced as part of reprofiling the frog with a hand-held grinder depends very much on the skill and experience of the operator.
  • the object of the present invention is now to provide a device of the type mentioned, with an exact guidance of the grinding member with respect to the sanding or copying vertical profile is possible.
  • Fig. 1 a highly schematized plan view of the heart area of a switch
  • Fig. 2 an enlarged side view of the device according to the invention in the labor input during reprofiling a heart piece
  • a switch 1 a heart 2, which is connected to a rail 3 of a main track 4 and a rail 5 of a side track 6 and positioned between two wing rails 7.
  • the area of the top of the heart 2 is according to regulations slightly lower than a running surface 8 of the subsequent rail 5.
  • a device 10 for reprofiling the core 2 is indicated, which will be described in detail below.
  • the copying device 10 essentially consists of a grinding machine 11 with a grinding frame 12, which is provided with a respective copying roller 13 or 14 at the end and can be supported on the running surface 8 of the rail 5 to be processed.
  • the spaced apart in the track longitudinal direction copy rollers 13,14 are rotatable about normal to the longitudinal direction of the track extending axes 17 and form a copy base 26 for reprofiling the rail 5.
  • a grinding member 18 which is displaceable by means of a motor 19 in rotation and manually perpendicular to the rail 5 (or to the heart 2) is deliverable.
  • changeable trained copy base 26 is - in the track longitudinal direction of the grinding frame 12 distances - an additional third copy roller 15 is provided.
  • This is arranged at the free end 28 of a long stretched trained Rollenveréesung 16 which is releasably fixed with its other, opposite end 29 by means of a clutch 27 on the grinding frame 12.
  • the copying roller 15 is associated with a copying rail 20 which is releasably fixable on the rail (for example by means of magnetic fastening means 25) and has a guide surface 23 which serves to support and guide the copying roller 15 in height.
  • the guide surface 23 of the (for example formed from flat steel) copy rail 20 is formed curved according to a desired geometry of the core piece 2.
  • the distance between the third copying roller 15 and the grinding member 18 is designated A, while the distance between the other end-side copying roller 13 and the grinding member 18 is designated B.
  • the guide surface 23 of the copy rail 20 thus stands to the ramp 9 in an exact geometric relationship, which is determined by the relation between the two distances A and B.
  • the grinding member 18 of the grinding machine 11 is thereby guided automatically and exactly in height.
  • a third copy roller 15 having - roller extension 16 is connected to the grinding frame 12 by means of a joint 30.
  • the roller extension 16 is pivoted downwards into the operating position shown here and fixed in this position, wherein the copying roller 15 supported on the copying rail 20 and thereby the copying base 26 is extended.
  • Fig. 4 shows a further variant of an inventively designed copying device 10.
  • the grinding frame 12 has a longitudinal guide 24 which extends in the longitudinal direction of track and in which a roller extension 16 is slidably mounted, at whose free end 28 one of the two copy rollers 13 ,.14 is mounted ,
  • the copying base 26 can be extended here by simply longitudinally displacing the roller extension 16 in the longitudinal direction of the track - in the longitudinal guide 24 relative to the grinding frame 12 - and fixing the same in its end position, this end position is determined by a predefined desired distance of the copying roller 14 from the grinding member 18.
