Abstract
A mobile machine arrangement for surfacing a track comprises a ballast excavating chain, a ballast cleaning screen, and conveying devices arranged rearwardly thereof for returning the cleaned ballast into respective ones of the cribs. Thrust tamping tools immersible in the cribs are arranged rearwardly of the ballast returning devices, and a track correction unit is arranged between the ballast excavating chain and the thrust tamping tools for moving the track into a desired position.
Claims8
A mobile machine arrangement for surfacing a track resting on ballast, the track consisting of two rails fastened to ties defining cribs therebetween, and the machine arrangement being adapted to move continuously on the track in an operating direction, which comprises the combination of
- (a) means for removing the ballast,
- (b) means for cleaning the removed ballast and for returning cleaned ballast under the track ties, and
- (c) additional means arranged rearwardly of the ballast cleaning means in said direction for filling the cribs with clean ballast, with
- (d) means arranged rearwardly of the additional means in said direction for tamping the ballast in the cribs filled with clean ballast and under the ties adjacent thereto, the tamping means having (1) thrust tamping tools immersible in the cribs,
- (e) a displacement drive operable to displace the tamping means in said direction relative to the continuous movement of the ballast removing, cleaning and crib filling means, and
- (f) track correction means arranged between the ballast removing means and the thrust tamping tools for moving the track into a desired position.
A mobile machine arrangement for surfacing a track resting of ballast, the track consisting of two rails fastened to ties defining cribs therebetween, and the machine arrangement being adapted to move on the track in an operating direction, which comprises the combination of
- (a) a machine frame,
- (b) a drive for moving the machine frame in the operating direction,
- (c) means for delivering metered amounts of clean ballast into respective ones of said cribs for filling the cribs, with
- (d) means mounted on the machine frame for correcting the position of the track,
- (e) a carrier frame mounted on the machine frame rearwardly of the track correcting means in said direction,
- (f) a displacement drive operable to displace the carrier frame in said direction relative to the machine frame,
- (g) means for tamping the clean ballast in the cribs filled with clean ballast and under the ties adjacent thereto mounted on the carrier frame, the tamping means having (1) thrust tamping tools immersible in the cribs, and
- (h) a reference system associated with the machine frame for controlling the track correcting means.
