Abstract
An arrangement of grinding modules in a track grinder wherein a radial mismatch in narrow track bend radii can be considered in an exact manner without occurrence of constraining forces, enabling reprofiling to be reproduced in a simple manner. The arrangement provides a grinding tool with five degrees of freedom. Each grinding module is accommodated in an at least approximately vertical manner with a frame and in an at least horizontally manner on the frame with a holder. A housing in the holder is pivotably arranged around a shaft that is at least approximately parallel to the track to be ground. The grinding tool in the housing can be adjusted in a rectangular manner in relation to the track to be ground.
Claims10
A rail grinding machine for grinding at least one rail, comprising:
- a frame movably mounted in the rail grinding machine and having frame actuators to move said frame at least vertically relative to a rail to be ground;
- grinding modules, each including a grinding machine and grinding machine actuators for moving said grinding machine relative to said frame to move vertically relative to the rail, horizontally transverse relative said rail, pivotally relative the rail about an axis substantially parallel to the rail;
- and
- measurement wheels, one of said measurement wheels being assigned to each of said grinding modules, measurement wheel actuators for effecting relative movement of said measurement wheels and said grinding modules in a direction horizontally transverse to the rail.
