Description

[0001]
[Industrial applications]
The present invention is a machine for cleaning a ballast ballast of a track, a machine frame supported on a rail traveling cart, and a sieving device supplied with ballast by a scraping device having a rotatable scraping chain, A conveyor device for dropping the cleaned ballast onto a track.
[0002]
[Prior art]
Machines of this type are already known from many publications. For example, AT 398 096 describes a machine capable of running on a track, in which a ballast scraping device is mounted on a long machine frame in a height-adjustable manner. The machine has an endless ballast scraping chain which is guided through the underside of the track during operation, by means of which the ballast is picked up from the track bed and conveyed to a screening device. The waste is separated from the ballast in this sieving device and is conveyed to the end of the machine, in the working direction, in front of the machine for discharge. The cleaned ballast is dropped again on the track lifted by the lifting device via the conveyor device. Additionally or alternatively, new ballast (or other floor material needed for track renewal) is supplied from the rear end of the machine and dropped and leveled on an open plane. At the beginning of the operation of this type of cleaning machine, a passage must first be formed in the ballast bed below the track, allowing passage of the ballasting chain.
[0003]
DE 22 26 612 A discloses a ballast ballast-cleaning machine, which comprises two ejection devices configured as ejection beams with a circulating endless ejection chain mounted on each longitudinal side of the machine frame. Is disclosed. These extraction beams are rotatable and height-adjustable about a vertical pivot center axis provided at one of their longitudinal ends, and are lowered to the side of the track bed for ballast extraction and on both sides. From the grid between the rails of the track and the sleepers. As a result, the ballast below the grid of the track is carried out to the side of the track, and is further supplied to the cleaning sieving device via the conveyor device extending obliquely upward.
[0004]
It is also known to remove ballast from the track bed by suction. Such a suction machine is described, for example, in AT 384 446 B, which comprises a suction device formed from three nasal suction tubes arranged side by side in the machine direction. At the lower end of each suction tube, which has a suction opening, is a rotatable removal element for loosening the clumped ballast just before suction. The ballast cleaned in the sieving device is returned to orbit again.
[0005]
Further ballast suction machines are known, for example, from DE 82 36 650 U or DE 21 36 306 A.
[0006]
[Problems to be solved by the invention]
It is an object of the present invention to provide a ballast cleaning machine of the above-mentioned type which can be used reasonably and versatilely while maintaining the structural basic elements which have already gained popularity.
[0007]
[Means for Solving the Problems]
According to the invention, the above-mentioned object is achieved, according to the invention, in a machine of the type mentioned at the outset, having a suction tube which can be adjusted in height and in the lateral direction via a drive, the suction tube taking in ballast and This is solved by having a negative pressure device connected to the suction opening via a suction tube.
[0008]
【The invention's effect】
With the machine according to the invention configured as described above, the measures required at the start of the operation, in particular the formation of the so-called "Kofferloch", can be significantly accelerated. The ballast removal in the ballast bed required for setting the ballast scraping chain in the bed is performed very quickly and without any problems by means of suction pipes without any manual work, in this case the ballast removed. There is no need to accumulate beside the track or to carry it out specially. A further advantage is that the drive provides a labor-friendly remote operation, which eliminates the danger to the operating personnel due to the unlocked adjacent track, especially when combined with the arrangement of claim 2. You. In addition, it is possible to structurally solve the problem that the suction tube of the present invention is installed later in a ballast roadbed cleaning machine that is already in use.
