Definitions

  • the invention relates to a device and a method for material processing of the frog point of a frog of a switch arrangement of a track system, in particular for reprofiling the geometry of the wheel overrun area of a frog point.
  • Frogs are known to be important components of switch arrangements in rail construction and are used to enable rail vehicles with flanged wheels in the area of the switch arrangement, where two tracks separate or merge, to change from one track to another track.
  • the inevitable gaps in the running surface in the area of the frogs lead to impacts that lead to severe signs of wear on the frog, in particular the tip of the frog.
  • Damage to the frog caused by wear and tear is regularly repaired by means of repair welding.
  • the correct geometry of the frog must then be restored, for example, the tip of the frog must be lowered appropriately or the desired longitudinal height profile must be generated. This is currently often done by laborious manual grinding.
  • the precise manufacture of the required tip lowering and wheel overrun areas in accordance with the applicable specifications is hardly possible by hand with the specified low tolerances, and compliance with the tolerances must be constantly checked using a ruler and gauges.
  • Previous measurement of the frog using laser scanners to determine reference values and regular checking of the manual reprofiling using lasers is time-consuming and does not always lead to an improvement.
  • the object of the present invention is to provide a means by means of which a desired frog geometry, for example a desired lowered crossing point, can be restored in situ in the wheel overrun area of a worn or damaged frog of a switch arrangement.

Abstract

L'invention concerne un dispositif (1) et un procédé d'usinage de matériau de la pointe de cœur (102) d'un cœur de croisement (101) d'un agencement de points (100) d'un système de voie, en particulier pour reprofiler la géométrie de la région de transfert de roue d'une pointe de cœur (102). Le dispositif (1) selon l'invention comprend un cadre de base (2) et un cadre de maintien (3), et une machine de fraisage ou de meulage (4) qui est maintenue par le cadre de maintien (3). Le dispositif (1) peut être fixé, par l'intermédiaire du cadre de base (2), à l'agencement de points dans la région du cœur de croisement (101). La tête de fraisage ou de meulage (41) de la machine de fraisage ou de meulage (4) peut être orientée de manière flexible et précise pour reprofiler la pointe de cœur (102) par l'intermédiaire d'une combinaison de possibilités de réglage de la position du cadre de maintien (3) par rapport au cadre de base (2) et de la machine de fraisage ou de meulage (4) dans le cadre de maintien (3).
