Definitions

  • the invention relates to a grinding machine for rails, in particular container crane rails, according to the preamble of claim 1. It is also suitable for grinding single and double rail tracks.
  • this object is solved by the characterizing features of the first claim and this solution by the Substantiated sub-claims.
  • this is the case of horizontal and vertical adjustments of the grinding modules, this includes the case that curved rails for receiving centrifugal forces on the objects moving on them can be inclined transversely to the rail longitudinal direction.
  • an abrasive module is used and these are in accordance with the profile of the rail head in transverse to the respective rail from the vertical angle adjustable (tiltable).
  • it has proved to be favorable to design the base by two arranged on running and track rollers or wheels and their bearing blocks bridges, between which a base frame is arranged substantially horizontally and transversely to the rail longitudinal direction adjustable. In this case, located on the mutually facing sides of the bridges and the base frame guides and synchronously acting adjusting means, which not only accomplish the transverse adjustment, but also connect the bridges with the base frame.
  • each bridge at least one bearing body with a track roller with a ring gear and a roller is adjustably mounted, which are arranged in the rail longitudinal direction to each other and the center distance is large enough to exert a compensating effect in short or sudden irregularities in the rail head profile.
  • a mounting flange is fixed, which is pivotally connected to this bridge to two mutually parallel and to the direction of the transverse adjustment axes and avoids constraining forces in this way.
  • the mounting flange is used to connect the grinder to a crane or trolley, which then also drives the grinder to move along the rail.
  • the grinding machine can also have its own drive, which drives at least one track roller and is preferably used when grinding railway tracks.
  • a pivoting frame is pivotally mounted about an axis which is substantially parallel to the direction of the transverse adjustment.
  • a grinding tool is rotatably mounted about an axis whose direction and position is variable and whose initial position is directed parallel to the Schwenkachsedes of the frame or perpendicular to the initial positions of the Schleifinodule the base frame.
  • the latter grinding tool is part of an abrasive module which is height-adjustable and laterally adjustable on the pivoting frame and mounted pivotably about an axis which runs essentially parallel to the rail longitudinal direction.
  • the grinding module mounted on the swing frame is used to grind the side surfaces of the rail head. Since the rail head has two opposite side surfaces, two grinding modules in a suitable arrangement and design for simultaneous grinding of the side surfaces can be provided on the swing frame. It is also possible to arrange a grinding tool for each side surface, wherein only one drive is provided for both grinding tools, which drives each grinding tool via a suitable gear. So that during the grinding process belonging to the swing frame track or roller can not jump from the rail is advantageously provided for the swing frame a printing device which is supported on the one hand on the base frame and on the other hand on the swing frame. Grinding modules and frames may be enclosed by housings connected to a dust extraction device.
  • the track rollers advantageously have the size, in particular of normal rail or rail wheels.
  • it is advantageous if it is connected to a transport vehicle with retractable and extendable road wheels or if it is aufattelbar on a road transport vehicle.
