Abstract

A track laying car has a rear undercarriage for moving the car in a working direction on the track rails and track-laying bogie for selective engagement with the ballast bed for moving the car on the ballast bed in the absence of a track for the rear undercarriage. An endless scraper conveyor chain is vertically adjustably mounted on the car and includes a transverse stringer arranged for engagement with the ballast bed for planing the ballast bed and conveying excess ballast from the planed bed, the stringer being arranged in front of the bogie. A tie conveyor is mounted on the car to convey ties in a direction opposite to the working direction to the planed ballast bed behind the bogie and to lay the conveyed ties sequentially on the planed ballast bed, and a ballast conveyor moves in a path arranged to enable the ballast conveyor to receive the excess ballast and to convey it in a direction opposite to the working direction to the rear end of the car where the ties have been laid on the planed ballast bed.

Claims4

Dependent claims

An apparatus for laying track comprised of rails and ties on a ballast bed, comprising the combination of

(a) an elongated bridge-like carrier frame having a rear end,
(b) a rear undercarriage for moving the carrier frame in a working direction on the track rails, the undercarriage supporting the carrier frame adjacent the rear end thereof,
(c) another undercarriage supporting the carrier frame adjacent the rear undercarriage and retractably arranged on the carrier frame for selective engagement with the ballast bed for moving the carrier frame in the working direction on the ballast bed in the absence of a track for the rear undercarriage,
(d) an endless scraper conveyor chain vertically adjustably mounted on the carrier frame and including a transversely extending stringer arranged for engagement with the ballast bed upon vertical adjustment of the conveyor chain for planing the ballast bed and conveying excess ballast from the planed ballast bed, the stringer of the conveyor chain being arranged in front of the other undercarriage,
(e) conveyor means mounted on the carrier frame and arranged to convey ties in a direction opposite to the working direction to the planed ballast bed behind the other undercarriage and comprising a mechanism for laying successive ones of the conveyed ties spacedly on the planed ballast bed between the other undercarriage and the rear undercarriage, and
(f) a ballast conveyor moving in a path arranged to enable the ballast conveyor to receive the excess ballast and to convey the excess ballast in a direction opposite to the working direction to the rear end of the carrier frame where the ties have been laid on the planed ballast bed, a transversely extending portion of the path of the ballast conveyor intersecting the path of the conveyor means in the region of the mechanism.
