Abstract
A method for continuously consolidating ballast under a track comprising rails and sleepers which are arranged transversely to the rails by a machine having tamping picks, comprises causing the tamping picks to pick up the ballast in front of the sleeper ends and push the ballast under the sleeper ends by a cycle of shovel movements comprising a consolidating movement in a direction which is parallel to the sleepers, an upward movement occurring immediately in front of the sleeper end faces, and a return movement counter to the consolidating movement, and continuously causing the tamping picks to repeat the cycle of shovel movements. Desirably, a continuous forward movement is superimposed on the cycle of shovel movements.
Claims23
A method for continuously consolidating ballast under a track, comprising rails and sleepers which are arranged transversely to said rails and have sleeper ends with sleeper end faces, by a machine having tamping picks, comprising
- raising said track to a desired position,
- causing said tamping picks to push said ballast in front of and under said sleeper ends by a cycle of shovel movements comprising a consolidating movement in a direction which is perpendicular to said rails, an upward movement occurring immediately in front of said sleeper end faces, and a return movement counter to said consolidating movement, and
- continuously causing said tamping picks to repeat said cycle of shovel movements.
A tamping machine for continuously consolidating ballast under a track comprising rails and sleepers which are arranged transversely to rails and have sleeper ends with sleeper end faces, said machine comprising
- a machine frame supported on rail bogies, a tamping unit having tamping picks which are movable in directions perpendicular to a longitudinal direction of said machine by means of positioning drives,
- said positioning drives causing said tamping picks to push said ballast in front of and under said sleeper ends by a continuous cycle of shovel movements comprising a consolidating movement in a direction which is perpendicular to said rails an upward movement occurring immediately in front of said sleeper end faces, and a return movement counter to said consolidating movement,
- wherein said machine continuously moves forward in said longitudinal direction, and all of said tamping picks are arranged on longitudinal sides of said machine and in front of said sleeper ends.
