DESCRIPTION:
BRIEF SUMMARY
The invention relates to a machine for treating the ballast bed of a track, which comprises a machine frame means supported on undercarriages, which frame is provided with a suction unit with a suction pipe having a suction opening for sucking off crushed rock and being vertically and laterally adjustable.
Such a suction machine is known from DE 82 36 650 U. This machine is provided with a suction pipe projecting beyond the machine frame, with which crushed rock is sucked off from the track and guided to a collecting container. The crushed rock is cleaned with the help of a vibratory screen and is thrown back on to the track with the help of a transverse conveyor belt.
A further such suction machine is known from DE 21 36 306 A. The suction nozzle attached to the projecting suction pipe is provided with vibrators for loosening the crushed rock to be sucked off. The suction pipe is supported by a rotatable and swivellable carrier frame above the driver's cabin.
From AT 384 446 B a suction machine is known which is provided with a suction arrangement formed by three suction nozzles adjacently arranged in the transverse direction of the machine. At the lower end of each suction pipe, which is provided with a suction opening, there is disposed a rotating clearing member so as to loosen up encrusted rock immediately prior to the suction.
A further machine known from DE 22 26 612 A for treating a ballast bed of a track is provided with two clearing apparatuses each attached on a longitudinal side of a machine frame, which apparatuses are formed as clearing beams with a rotating endless clearing chain. Said clearing beams are rotatable about a vertical pivot axle provided at their one longitudinal end and vertically adjustable and are pivoted upwardly about a horizontal axis extending in the transverse direction of the machine when being taken out of operation.
For removing the crushed rock, the clearing apparatuses are lowered to the ballast bed shoulders and thereafter swivelled in from both sides below the track grid, with crushed rock situated below the track grid being conveyed towards the track shoulders and supplied to a screening unit for cleaning by an upwardly inclined conveyor arrangement.
It is the object of the present invention to provide a machine of the kind mentioned above which allows the complete removal of the crushed rock both for small as well as large areas of the ballast bed of a track.
This object is achieved with a machine of the kind mentioned above by providing a clearing apparatus which is arranged at a distance from the suction opening of a suction pipe in the longitudinal direction of the machine and is provided with an endless clearing chain rotatable by a drive for removing the crushed rock disposed below the track, the clearing apparatus and the suction pipe being provided with separate drives for lateral and vertical adjustment independently from one another.
With this combination of features two different systems for removing crushed rock are available for achieving improved work results in connection with the highest possible removal of crushed rock even at narrow places in an advantageous manner, usable either jointly or separately. Favourably, the substantially larger part of the ballast bed of the track situated below the track grid is transportable by the more powerful mechanical clearing apparatus in the transverse direction of the machine towards the shoulder of the ballast bed, whereas the suction pipe with the smaller cross section is immersible in an unimpeded manner and, parallel to the clearing apparatus, at narrow positions which cannot be reached by the clearing chain. The crushed rock collected in the ballast bed shoulder area with the help of the clearing chains can optionally, depending on the various operational conditions, either be sucked off or be conveyed off by a mechanical system. In the event that the collection of crushed rock is situated between a platform and the track grid, for example, only suction is possible, as owing to the narrow gap there is n
