COMBINED TRACK BALLAST CLEANING AND CONSOLIDATING MACHINE

摘要

A mobile installation for cleaning the ballast supporting a track and subsequently leveling the track and tamping ballast under the ties of the leveled track comprises a ballast cleaning machine movable in an operating direction along the track and a track leveling, lining and tamping machine following the ballast cleaning machine in the operating direction, the track leveling, lining and tamping machine. The latter machine comprises a self-propelled machine frame, two undercarriages supporting the frame for movement in the operating direction along the track, the undercarriages being sufficiently spaced apart in this direction to permit lifting and lateral movement of the track therebetween, a ballast tamping unit mounted on the frame between the undercarriages and comprising pairs of vibratory and reciprocatory tamping tools for tamping ballast under respective ones of the ties, a track lifting and lining unit mounted on the machine frame between the undercarriages and ahead of the ballast tamping unit in the operating direction, and a ballast receiving and storage container mounted on the machine frame ahead of the track lifting and lining unit, the container having adjustable outlet ports for distributing ballast in the cribs. A conveyor arrangement is mounted on the machine frame for receiving cleaned ballast from the ballast cleaning machine and for conveying the received cleaned ballast to the ballast receiving and storage container.
