Abstract

A mobile machine for aspirating ballast from a ballast bed comprises a machine frame extending in a longitudinal direction and supported by undercarriages running on a track. Mounted on the machine frame are a ballast aspirating device comprising a short suction inlet pipe defining a suction inlet port, and a ballast excavating device vertically adjustable by drive means linking the ballast excavating device to the machine frame. The ballast excavating device comprises a substantially horizontally extending beam having opposite ends, a guide roller mounted on each beam end and an endless ballast excavating chain trained over the guide rollers, the beam being pivotal about a vertical axis at one of the beam ends and arranged in an operating position laterally adjacent one of the tie ends at one of the ballast bed shoulders and the suction inlet port being vertically adjustable in said operating position.

Dependent claims

A mobile machine for aspirating ballast from a ballast bed supporting a track consisting of rails fastened to ties having opposite ends at shoulders of the ballast bed, which comprises

(a) a machine frame extending in a longitudinal direction and supported by undercarriages running on the track, and mounted on the machine frame,
(b) a ballast aspirating device comprising
(1) a short suction inlet pipe defining a suction inlet port, and
(c) a ballast excavating device vertically adjustable by drive means linking the ballast excavating device to the machine frame, the ballast excavating device comprising
(1) a substantially horizontally extending beam having opposite ends,
(2) a guide roller mounted on each beam end and
(3) an endless ballast excavating chain trained over the guide rollers,
(4) the beam being pivotal about a vertical axis at one of the beam ends and the vertical axis being arranged in an operating position laterally adjacent one of the tie ends at one of the ballast bed shoulders and the suction inlet port being vertically adjustable,
(d) a carrier frame vertically spaced from the beam and extending transversely relative to the longitudinal direction of the machine frame,
(1) the carrier frame being an elongated beam extending in a longitudinal direction transverse to the longitudinal direction of the machine frame,
(e) a vertical carrier affixing the one beam end to the carrier frame,
(f) a transverse guide affixed to the machine frame, the elongated beam being displaceably mounted on the transverse guide for displacement in said transverse direction, and
(g) a longitudinal displacement drive connected to the elongated beam.
