Abstract
A mobile rail contouring machine is arranged for continuously milling such running surface irregularities as ripples, corrugations and overflow metal from rail heads during the continuous movement of the machine along a railroad track. The machine comprises a frame, a rail contouring tool mounting linked to the frame, guide rollers for vertically and laterally guiding the mounting without play along the sides and the running surface of the rail head of each rail and for pressing the mounting thereagainst, and a rail contouring tool head including a tool holder arranged on the mounting. A rail contouring tool is mounted in the tool holder and the tool head is displaceable with respect to the mounting in directions extending parallel and perpendicularly to the track.
Claims30
A mobile rail contouring machine mounted on a railroad track for continuous movement in an operating direction, the track including two rails each having a rail head defining a gage side, a field side and a running surface, the gage and field sides extending from the running surface to a lower edge of the rail head, the machine being arranged for continuously removing such running surface irregularities as ripples, corrugations and overflow metal during the continuous movement and comprising
- (a) a frame,
- (b) a rail contouring tool mounting linked to the frame,
- (c) guide roller means for vertically and laterally guiding the mounting without play along the rail head of one of the rails, the guide roller means including
- (1) guide rollers engaging and vertically guiding the mounting along the running surface of the one rail head, and
- (2) additional guide rollers below said guide rollers for laterally guiding the mounting along a selected one of the sides of the rail head and engaging the selected rail head side in a region extending from the lower edge to below the running surface,
- (d) drive means linking the mounting to the frame and for vertically adjusting the mounting relative to the running surface of the rail head of the one rail and for pressing the mounting thereagainst,
- (e) a rail contouring tool head including a tool holder arranged on the mounting,
- (f) a rail contouring tool mounted in the tool holder, and
- (g) hydraulic drive means for displacing the tool head with respect to the mounting along guide columns in directions extending substantially parallel to the track and substantially perpendicularly thereto.
