A mobile track leveling, lining and tamping apparatus comprises a frame assembly mounted on undercarriages and mounting a tamping head, a track shifting unit and a reference system for controlling the track leveling and lining by the track shifting unit, and a drive for advancing the frame assembly in the working direction along the track. The frame assembly comprises a main frame and an auxiliary frame mounted on at least one of the undercarriages, one end of the main frame being adjacent one end of the auxiliary frame. A coupling is arranged between the ends of the main and auxiliary frames to permit at least temporary adjustment of the spacing between the frame ends and relative movement between the frames in the working direction. Track surfacing equipment is mounted on the auxiliary frame and the drive comprises a drive for the auxiliary frame. A control is operatively associated with the auxiliary frame drive for selectively driving the auxiliary frame with the main frame and relative to the main frame.
A mobile track leveling, lining and tamping apparatus comprising frame means mounted on undercarriages for mobility on the track in a working direction, tamping means, track shifting means and a reference system for controlling the track leveling and lining by the track shifting means mounted on the frame means, means for actuating the tamping and track shifting means, and means for driving the frame means in the working direction, the frame means comprising a main frame and an auxiliary frame mounted on at least one of the undercarriages, one end of the main frame being adjacent one end of the auxiliary frame, a coupling between the ends of the main and auxiliary frames, the coupling being arranged to permit at least temporary adjustment of the spacing between the frame ends and relative movement between the frames in the working direction, track surfacing means mounted on the auxiliary frame, the driving means comprising a drive for the auxiliary frame, and a control operatively associated with the auxiliary frame drive for selectively driving the auxiliary frame with the main frame and relative to the main frame, the control being arranged to control the auxiliary frame drive for non-stop forward movement of the auxiliary frame in the working direction at a pre-adjustable constant speed, whereby the auxiliary frame moves away from the main frame at said speed when the main frame is stopped during successive, intermittent track leveling, lining and tamping cycles, and the speed is pre-adjusted to one lower than that of the main frame in movement whereby the main frame approaches the auxiliary frame during said movement.
A mobile track leveling, lining and tamping apparatus comprising frame means mounted on undercarriages for mobility on the track in a working direction, tamping means, track shifting means and a reference system for controlling the track leveling and lining by the track shifting means mounted on the frame means, means for actuating the tamping and track shifting means, and means for driving the frame means in the working direction, the frame means comprising a main frame and an auxiliary frame mounted on at least one of the undercarriages, one end of the main frame being adjacent one end of the auxiliary frame, a coupling between the ends of the main and auxiliary frame, the coupling being arranged to permit at least temporary adjustment of the spacing between the frame ends and relative movement between the frames in the working direction, track surfacing means mounted on the auxiliary frame, the driving means comprising a drive for the auxiliary frame, a control operatively associated with the auxiliary frame drive for selectively driving the auxiliary frame with the main frame and relative to the main frame, dye spraying means mounted in a forward section of the frame means for applying a colored mark on the track ties and ballast in the direction of track elongation for indicating lining deviations of the track, the dye spraying means being arranged for continuously applying the colored mark as a marking line extending in the direction of track elongation, and a television observation means mounted in a rear section of the frame means for observing the colored marking line in the operation of the track shifting means for lining the track.
A track surfacing method wherein a mobile track leveling, lining and tamping apparatus comprising frame means mounted on undercarriages for mobility on the track is advanced intermittently along a track between successive tamping stations, the apparatus being stopped at each of the stations for tamping, the frame means comprising a main frame and an auxiliary frame mounted on at least one of the undercarriages, one end of the main frame being adjacent one end of the auxiliary frame, and track surfacing means being mounted on the auxiliary frame, which comprises the step of advancing the auxiliary frame non-stop at a substantially constant speed, the auxiliarly frame advancing in relation to the main frame while the main frame is stopped at the successive tamping stations and the main frame approaching the auxiliary frame as the main frame advances from station to station, the track surfacing means on the auxiliary frame continuously advancing at the constant speed while the main frame of the apparatus advances intermittently.
A track surfacing method wherein a mobile track leveling, lining and tamping apparatus comprising frame means mounted on undercarriages for mobility on the track is advanced intermittently along a track between successive tamping stations, the apparatus being stopped at each of the stations for tamping, the frame means comprising a main frame and an auxiliary frame mounted on at least one of the undercarriages, one end of the main frame being adjacent one end of the auxiliary frame, and track surfacing means comprising a centrally arranged ballast plow and associated lateral ballast plows for shaping and smoothing the ballast bed of the track mounted on the auxiliary frame, which comprises the step of advancing the auxiliary frame continuously and independently of the main frame to move the ballast plows forwardly along the track, ballast being continuously moved laterally inwardly by the lateral ballast plows towards the tamping stations as the auxiliary frame advances.
