Description

DRIVABLE DEVICE FOR WORK ON TRACK SUPERSTRUCTURES}

The present invention relates to a workable device for working in the superstructure of a track of the type described in the preamble of claim 1, in particular for machining the rail head of the track lying on a ballast bed.

Devices of this type are known from Applicant's DE 32 22 208 PS. The device has a milling head that is rotationally driven and is mounted to a bogie frame that includes a milling head driver and interacts with means for guiding the milling head in the vertical and / or transverse directions, the milling head being adapted to the rail head. With a series of milling head tools for machining, the profile of the rail head consists of generally circular partial arcs of different radius, each partial arc forming a track on the running surface of the track and the milling head It has as many blades as the partial arc or track of each rail head to be milled. It has been found that the conventionally known apparatus is very effective as a means for milling rail heads compared to the rail planers previously used, in that the interruption of work is considerably shorter when executing machining operations on rails. However, in such a milling apparatus, it is generally required to carry out another processing step of polishing the rail to obtain a smoother milling contour for the purpose of restoring the rail contour. During milling of tracks with conventionally known apparatus, so-called milling ridges occur in each milling track. That is, a pattern in which the raised and concave sections are periodically repeated in the driving direction occurs, although it is difficult to visually check them, they must be removed by an additional polishing step.

In contrast to the prior art based on DE 32 22 208 PS, the object of the present invention is to provide a comprehensive device for performing work on track superstructures, in particular for tracks laid on gravel beds, to ensure simpler and faster tool changeover.
