Abstract
A machine having a ballast take-up device (5) for taking up ballast located underneath a track has an endless clearing chain (8) guided in a chain channel (14). In a connecting joint (18) from a transverse channel (15) to a transport channel (17), a ballast deflector blade (20) pivotable about a pivot axis (19) is fastened. Arranged on said ballast deflector blade (20) is a ballast conveyor (24), designed for ballast transport in the direction towards a pivot axis (19) by means of a conveyor drive (23). With this, it is possible to expand the operating range of the ballast take-up device, as needed.
Claims8
1:
- A machine having a ballast take-up device for taking up ballast located underneath a track by means of an endless clearing chain (8) guided in a chain channel (14), wherein the chain channel (14) is composed of a transverse channel (15) located underneath the track (4), an empty channel (16) and a transport channel (17) provided for ballast transport, and a ballast deflector blade (20) pivotable about a pivot axis (19) is fastened in a connecting joint (18) from the transverse channel (15) to the transport channel (15, 17), wherein a ballast conveyor (24), designed for ballast transport in the direction towards the pivot axis (19) by means of a conveyor drive (23), is arranged on the ballast deflector blade (20).
2:
- The machine according to claim 1, wherein the ballast conveyor (24) is designed to be vertically adjustable relative to the ballast deflector blade (20) by means of drive.
3:
- The machine according to claim 2, wherein a guide (28) provided for vertical adjustment is arranged parallel to the pivot axis (19).
4:
- The machine according claim 1, wherein the ballast conveyor (24) is designed to be pivotable about an axis (28) extending perpendicularly to a blade plane (26) of the ballast deflector blade (20).
5:
- The machine according to claim 1, wherein the ballast conveyor (24) is designed as a screw conveyor rotatable about an axis of rotation (25).
6:
- The machine according to claim 1, wherein the ballast conveyor (24) is designed as a conveyor chain, having a number of blades (31), which is deflectable about two axes (30) spaced from one another.
7:
- The machine according to claim 1, wherein the ballast deflector blade (24) is designed to be adjustable about the pivot axis (29) by means of a pivot drive (21).
8:
- The machine according to claim 7, wherein an electronic sensor (33) provided for motion detection or for distance measuring is arranged preferably directly on the ballast deflector blade (20) for automatic actuation of the pivot drive (21).
