Description
- The invention relates to an installation for cleaning ballast of a track, consisting of several vehicles having machine frames supported on on-track undercarriages, including two shoulder clearing chains, positioned opposite one another with regard to a transverse direction of the track, for taking up the ballast located in a shoulder area adjoining sleeper ends, an endless clearing chain following the shoulder clearing chains with respect to a working direction of the installation and designed to be guided around the track for taking up the ballast located underneath the track, further including a screening installation, conveying devices for the transport of ballast, and a ballast introduction device. The invention also relates to a method for cleaning ballast of a track with an installation of this type.
- The cleaning of the ballast bed, to be carried out at regular intervals, poses great demands on the track maintenance machines used in the process regarding the treatment and transport of the ballast. Enormous amounts of ballast have to be treated and transported in an efficient and cost-saving manner.
- According to AT 514 806 B1, a vehicle combination for cleaning ballast of a track is already known. With respect to a working direction, first the ballast located in the track bed region adjoining sleeper ends is taken up by two shoulder clearing chains lying opposite one another in the transverse direction of the track. Then, the ballast located underneath the track is taken up by means of an endless clearing chain guided around the track. All of the excavated ballast is transported by means of a conveying device to a screening installation, is cleaned there and reintroduced into the track.
- Known from EP 0 629 744 A2 are a method and an installation for subgrade rehabilitation of a ballast bed of a track. In this, the ballast is excavated by means of two endless clearing chains which are guided around the track and arranged one following the other with regard to a working direction. The ballast taken up by the front clearing chain is comminuted in a stone crusher device and discharged by the rear clearing chain as a formation protection layer upon the earth formation exposed after removal of the remaining ballast.
- It is the object of the invention to provide an improvement over the prior art for an installation of the type mentioned at the beginning. A further object lies in showing a method for cleaning ballast of a track by means of an improved installation.
- According to the invention, this object is achieved in that a first conveying device for transport of ballast to the screening installation is associated with the shoulder clearing chains, a second conveying device for transport of ballast to a processing unit is associated with the endless clearing chain, and a third conveying device for transport of ballast to the screening installation is associated with the processing unit.
- This configuration enables a needs-based cleaning or renewal of the ballast bed of a track. Though the ballast located in a shoulder region adjoining sleeper ends is normally also contaminated, it is however not as heavily mechanically stressed during the service life as the ballast located underneath the track. The latter is heavily worn by direct loading during rail operations, which means that the sharp edges of the individual ballast stones, required for a stable structure of the track bed, no longer exist. These edges can be restored by appropriate processing of this portion of the ballast bed in a processing unit. The portion of the ballast bed less stressed does not need to be treated in this manner and can be fed directly to a screening installation. In this way, the flow rate of cleaned ballast and thus the working speed is increased as compared to conventional installations.
- A useful further development is realized in that the processing unit has a pre-separator and a crusher following the same. When the ballast passes through these two units, coarse contaminants are first separated out, and subsequently the edges are sharpened.
- In another advantageous embodiment, the processing unit is arranged on a separate processing vehicle having a machine frame supported on on-track undercarriages. The processing vehicle can thus be integrated with manageable technical expense into an installation or, if there is no need for processing, can be excluded from the installation. Likewise, the expansion of an already existing installation with a processing vehicle is facilitated.
- Several possibilities of incorporating the processing vehicle into the installation are conceivable: the installation can be configured in such a way that the processing vehicle is arranged between the shoulder clearing chains and the endless clearing chain, with regard to the working direction. It is also possible that the processing vehicle is arranged, with regard to the working direction, in front of the shoulder clearing chains and the endless clearing chain and behind the screening installation. Finally, it is also conceivable that the processing vehicle and the screening installation are arranged between the shoulder clearing chains and the endless clearing chain, with regard to the working direction.
- Such variants ensure high flexibility when retrofitting existing installations with a processing vehicle. In addition, the composition of the installation can be advantageously influenced in dependence on the construction site situation and the availability of installation components and material cars.
- The object of the invention is also achieved by implementation of a method in which the ballast located underneath the track is first fed to a processing unit and thereafter transported to the screening installation. By the separate, condition-dependent taking-up of the ballast, no ballast quantities accrue which are subjected to treatment which is either too intensive or too inefficient. Thus, neither the clearing chains nor the components of the processing unit or the conveying devices or the screening installation are overstressed. These can be dimensioned smaller and based on need.
- A particularly advantageous embodiment of the method is achieved in that the ballast located underneath the track is first transported to a pre-separator and then fed to a crusher. Method steps of this kind enable an optimal pre-cleaning and edge sharpening of the ballast worn by the rail operations.
- The invention will be described below by way of example with reference to the accompanying drawings. In a schematic manner,
FIGS. 1 to 3 show side views of different variants of an installation for cleaning ballast of a track. - Visible in
FIGS. 1 to 3 areinstallations 1 for cleaningballast 2 of atrack 3. Aninstallation 1 of this type consists ofseveral vehicles 6 havingmachine frames 5 supported on on-track undercarriages 4. Theinstallation 1 has twoshoulder clearing chains 7, lying opposite one another in a transverse direction of the track, for taking up theballast 2 located in ashoulder area 8 adjoining sleeper ends, and anendless clearing chain 10, following theshoulder clearing chains 7 with respect to a workingdirection 9 of theinstallation 1 and designed to be guided around thetrack 3, for taking up theballast 2 located underneath thetrack 3. Theinstallation 1 is further equipped with ascreening installation 11 for ballast cleaning, withconveying devices ballast 2, and with aballast introduction device 12. - A
first conveying device 13 is designed for the transport ofballast 2 from theshoulder clearing chains 7 to thescreening installation 11. Associated with theendless clearing chain 10 is asecond conveying device 14 for the transport ofballast 2 to aprocessing unit 16 with which is associated athird conveying device 15 for the transport ofballast 2 to thescreening installation 11. Each of theconveying devices processing unit 16 has a pre-separator 17 and acrusher 18 following the same. All of the drives, not further shown, of the listed devices and units as well as motive drives are supplied with energy by acentral energy unit 19. Theprocessing unit 16 is arranged on aseparate processing vehicle 20 having amachine frame 5 supported on on-track undercarriages 4. - As can be seen in
FIG. 1 , theprocessing vehicle 20 is arranged between theshoulder chains 7 and theendless clearing chain 10, with regard to the workingdirection 9. - In the
installation 1 shown inFIG. 2 , theprocessing vehicle 20 is arranged in front of theshoulder clearing chains 7 and theendless clearing chain 10 and behind thescreening installation 11, with regard to the workingdirection 9. -
FIG. 3 shows an embodiment in which theprocessing vehicle 20 and thescreening installation 11 are arranged between theshoulder clearing chains 7 and theendless clearing chain 10, with regard to the workingdirection 9. - The method for cleaning
ballast 2 of atrack 3 by means of aninstallation 1 will be described in more detail below. First, theballast 2 is removed byshoulder clearing chains 7 in ashoulder region 8 adjoining sleeper ends and fed to thescreening installation 11. Then, theballast 2 located underneath thetrack 3 is removed by theendless clearing chain 10. Thisworn ballast 2 is first fed to theprocessing unit 16 and only afterwards transported to thescreening installation 11. Inside theprocessing unit 16, theballast 2 is first transported to a pre-separator 17 and then to acrusher 18. In the pre-separator 17, theballast 2 is separated from coarse contaminants before the edges of theballast 2 are sharpened in thecrusher 18. Prior to the treatment of theballast 2 in thescreening installation 11, the ballast quantities removed separately from one another are united again and together run through thescreening installation 11. From there, the cleanedballast 2 is transported counter to the workingdirection 9 by means of afourth conveying device 21 to aballast introduction device 12 situated behind theendless clearing chain 10, in order to be reintroduced into thetrack 3. The spoil accruing during the ballast cleaning is transported via afifth conveying device 22 to a front end of theinstallation 1 with regard to the workingdirection 9. Both the fourth and the fifth conveyingdevice
