Abstract

A mobile switch leveling, lining and tamping machine comprises a vertically and laterally adjustable leveling and lining tool carrier frame linked to the machine frame, a pair of flanged wheels supporting the carrier frame on a main track for mobility therealong, each flanged wheel engaging a respective rail and serving as a track lining tool, a respective power-operated, vertically and transversely adjustable track lifting tool mounted on the carrier frame for gripping each rail at one side thereof, a leveling and lining reference system including a main track position sensing device, the leveling and lining reference system controlling actuation of the track lifting and lining drives in response to the main track position sensed by the device, a vertically adjustable auxiliary device mounted on the machine frame for lifting a laterally adjacent track section, a power-actuated drive for laterally displacing the auxiliary device, and a measuring carriage associated with the machine and running on the laterally adjacent track section, the measuring carriage comprising a measuring beam extending transversely from the laterally adjacent track section to the machine frame for measurably monitoring the position of the laterally adjacent track section and a cross level connected to the measuring beam for measurably monitoring the superelevation of the adjacent track section.

Dependent claims

A mobile switch leveling, lining and tamping machine for vertically and laterally adjusting the position of a track switch comprised of a main track consisting of two rails fastened to ties, each rail having a field side and a gage side, and a track section laterally adjacent the main track, the machine comprising

(a) a machine frame,
(b) a leveling and lining tool carrier frame linked to the machine frame,
(c) power-actuated track lifting and lining drive means connecting the carrier frame to the machine frame for vertically and laterally adjusting the carrier frame,
(d) a pair of flanged wheels supporting the carrier frame on the main track for mobility therealong, each flanged wheel engaging a respective one of the rails and serving as a track lining tool,
(e) a respective power-operated, vertically and transversely adjustable track lifting tool mounted on the carrier frame for gripping each rail at one side thereof,
(f) a leveling and lining reference system including
(1) a main track position sensing device, the leveling and lining reference system controlling actuation of the track lifting and lining drive means in response to the main track position sensed by the device,
(g) a vertically adjustable auxiliary device mounted on the machine frame for lifting the laterally adjacent track section,
(h) a power-actuated drive for laterally displacing the auxiliary device, and
(i) a measuring carriage associated with the machine and running on the laterally adjacent track section, the measuring carriage comprising
(1) a measuring beam extending transversely from the laterally adjacent track section to the machine frame for measurably monitoring the position of the laterally adjacent track section and
(2) a cross level connected to the measuring beam for measurably monitoring the superelevation of the adjacent track section.
