Description

Die Erfindung betrifft eine Kehrmaschine zum Kehren eines Gleises, mit einem auf Schienenfahrwerken abgestützten Maschinenrahmen und mit diesem höhenverstellbar verbundenen, in Maschinenlängsrichtung voneinander distanzierten und jeweils eine senkrecht zur Maschinenlängsrichtung verlaufende Rotationswelle mit radial abstehenden, flexiblen Kehrelementen aufweisenden Kehrbürsten.The invention relates to a sweeper for sweeping a track, with a machine frame supported on rail bogies and connected to this in a height-adjustable manner, spaced apart from one another in the machine longitudinal direction and each having a rotary shaft running perpendicular to the machine longitudinal direction and having radially projecting, flexible sweeper elements.

Durch die US 4 554 697 ist bereits eine derartige Maschine zum Kehren eines Gleises bekannt, wobei unmittelbar vor dem vorderen Schienenfahrwerk und hinter dem hinteren Schienenfahrwerk jeweils eine Kehrbürste höhenverstellbar am Maschinenrahmen befestigt ist. Durch im Winkel zur Maschinenlängsrichtung angeordnete Ablenkorgane, die jeweils unmittelbar vor der Kehrbürste vorgesehen sind, wird der abgekehrte überschüssige Schotter seitlich in den Flankenbereich der Schotterbettung verlagert. Eine derartige Maschine ist jedoch für ein leistungsfähiges Kehren größerer Schottermengen nicht geeignet.Such a machine for sweeping a track is already known from US Pat. No. 4,554,697, with a sweeping brush being attached to the machine frame in a height-adjustable manner directly in front of the front rail carriage and behind the rear rail carriage. The deflected excess ballast is shifted laterally into the flank area of the ballast bed by means of deflection elements arranged at an angle to the machine longitudinal direction, which are each provided directly in front of the sweeping brush. However, such a machine is not suitable for efficient sweeping of large amounts of ballast.

Durch die japanische Gebrauchsmuster-Veröffentlichung 5001-81 ist auch eine Kehrmaschine bekannt, bei der zwischen zwei Schienenfahrwerken eine zwei Kehrbürsten aufweisende Baueinheit höhenverstellbar an einem Maschinenrahmen befestigt ist. Diese bekannte Maschine ist ebenfalls für eine leistungsfähige Schotterentfernung nicht geeignet.A utility sweeper is also known from the Japanese utility model publication 5001-81, in which a unit having two sweeping brushes is fastened to a machine frame in a height-adjustable manner between two rail carriages. This known machine is also not suitable for efficient ballast removal.

Durch die GB 1 040 104 B ist auch noch eine Maschine zum Verdichten des Schotters in den Schwellenzwischenfächern bekannt. Diese Maschine weist insgesamt drei Kehrbürsten auf, die den Verdichtaggregaten in Arbeitsrichtung vorgeordnet sind. Während eine Kehrbürste eine senkrecht zur Maschinenlängsrichtung verlaufende horizontale Rotationsachse aufweist, verlaufen jene der beiden anderen Kehrbürsten in Maschinenlängsrichtung. Mit diesen beiden letztgenannten Kehrbürsten besteht die Möglichkeit, den Schotter im Gleismittelbereich tiefer aus den Schwellenfächern zu kehren.GB 1 040 104 B also discloses a machine for compacting the ballast in the intermediate sleeper compartments. This machine has a total of three sweeping brushes, which are arranged upstream of the compacting units in the working direction. While a sweeping brush has a horizontal axis of rotation running perpendicular to the machine longitudinal direction, those of the other two sweeping brushes run in the machine longitudinal direction. With these two last-mentioned sweeping brushes, it is possible to sweep the ballast deeper out of the sleeper compartments in the area of the track.

Schließlich ist noch durch die US 5 097 608 ein Schotterpflug bekannt, der in seinem hinteren Endbereich eine höhenverstellbare Kehrbürste aufweist. Dieser ist ein Querförderband unmittelbar vorgeordnet, mit dem überschüssiger Schotter seitlich im Flankenbereich der Schotterbettung abwerfbar ist. Einem zwischen Schienenfahrwerken befindlichen, höhenverstellbaren Schotterpflug sind zwei weitere Kehrbürsten unmittelbar vorgeordnet, mit denen eine im Winkel zur Maschinenlängsrichtung verlaufende Schotterverteilung mit Hilfe des Schotterpfluges unterstützt werden kann.Finally, US 5 097 608 discloses a ballast plow which has a height-adjustable sweeping brush in its rear end region. This is directly upstream of a cross conveyor belt with which excess ballast can be thrown off to the side in the flank area of the ballast bed. Two additional sweeping brushes are located directly in front of a height-adjustable ballast plow located between rail bogies, with which a ballast distribution running at an angle to the machine's longitudinal direction can be supported with the help of the ballast plow.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung einer Maschine der gattungsgemäßen Art, mit der zusätzlich zu einer besonders effizienten Kehrleistung auch eine weitgehend gleichmäßige Gleiseinschotterung durchführbar ist.The object of the present invention is to create a machine of the generic type with which, in addition to a particularly efficient sweeping performance, a largely uniform track ballast can also be carried out.

Diese Aufgabe wird erfindungsgemäß mit der eingangs genannten Maschine dadurch gelöst, daß der in Arbeitsrichtung der Maschine vordersten bzw. ersten Kehrbürste von insgesamt wenigstens drei in Maschinenlängsrichtung voneinander distanzierten Kehrbürsten ein in Maschinenlängsrichtung verlaufendes Förderband zugeordnet ist, dessen höher gelegenes Abwurfende über einem Entladeöffnungen aufweisenden Schotterspeicher positioniert ist, und daß jeder Kehrbürste ein senkrecht zur Maschinenlängsrichtung verlaufendes Querförderband unmittelbar vorgeordnet ist.This object is achieved according to the invention with the machine mentioned at the outset in that the foremost or first sweeping brush of a total of at least three sweeping brushes spaced apart from one another in the machine longitudinal direction is assigned a conveyor belt running in the machine longitudinal direction, the higher discharge end of which is positioned above a ballast store having unloading openings and that each sweeping brush is immediately upstream of a transverse conveyor belt running perpendicular to the machine longitudinal direction.

Durch diese spezielle Merkmalskombination ist der besondere Effekt erzielbar, daß in Verbindung mit einer optimalen Kehrleistung gleichzeitig im selben Arbeitsgang bedarfsweise auch eine Schotterverteilung von Überschußbereichen in Gleisabschnitte mit zu wenig Schotter durchführbar ist. Dies ist vor allem durch die Kombination der in Arbeitsrichtung ersten Kehrbürste mit einem vorgeordneten Schotterspeicher möglich. Außerdem sind in vorteilhafter Weise Kehrbürsten mit unterschiedlichen, durch die Kehrfläche gebildeten Rotationskörpern einsetzbar. Damit sind insbesondere Gleisabschnitte, die sich aus Teilbereichen mit Holz- bzw. Betonschwellen zusammensetzen, unter Einsatz der jeweils passenden Kehrbürste sowie Vermeidung von Umrüstarbeiten optimal kehrbar. In Verbindung mit der gelenkigen Befestigung und den Spurkranzrollen ist auch eine exakte Höhenpositionierung der Kehrbürsten in bezug auf die Schwellenoberkanten durchführbar, so daß beim Einsatz mehrerer hintereinander angeordneter Kehrbürsten eine wahlweise Höhenabstufung möglich ist, um damit einerseits - insbesondere im Zusammenhang mit einer hohen Vorfahrtsgeschwindigkeit - einen wesentlich höheren Verschleiß der ersten Kehrbürste zu vermeiden und andererseits eine vorgeschriebene Absenktiefe der Bettungsoberfläche in bezug auf die Schwellenoberkante genau einzuhalten. Mit diesen obangeführten Vorteilen eignet sich die erfindungsgemäße Maschine ganz besonders für den Einsatz auf Hochgeschwindigkeitsstrecken, bei denen eine relativ große Absenkung der Schotteroberfläche mit einer besonders gleichmäßigen Gleiseinschotterung gefordert wird und aufgrund der in den meisten Fällen kurzen Gleissperren eine hohe Arbeitsleistung unumgänglich ist.With this special combination of features, the special effect can be achieved that, in connection with an optimal sweeping performance, a ballast distribution of excess areas in track sections with too little ballast can be carried out in the same work step if necessary. This is possible above all by combining the first sweeping brush in the working direction with an upstream ballast store. In addition, sweeping brushes with different rotating bodies formed by the sweeping surface can be used in an advantageous manner. This means that sections of track made up of sections with wooden or concrete sleepers in particular can be optimally swept using the appropriate sweeping brush and avoiding retrofitting work. In connection with the articulated fastening and the flanged wheels, an exact height positioning of the sweeping brushes in relation to the upper edge of the sleeper can be carried out, so that when The use of several sweeping brushes arranged one behind the other allows an optional height gradation, on the one hand to avoid significantly higher wear of the first sweeping brush - especially in connection with a high right of way speed - and on the other hand to precisely maintain a prescribed lowering depth of the bedding surface with respect to the upper edge of the sleeper. With these advantages mentioned above, the machine according to the invention is particularly suitable for use on high-speed lines, on which a relatively large lowering of the ballast surface with a particularly uniform track ballast is required and, due to the short track locks in most cases, a high work output is essential.

Mit der gelenkigen Ausbildung der Maschine nach den Merkmalen der Ansprüche 3 und 4 ist sichergestellt, daß auch in engeren Gleisbögen die seitliche Auslenkung der Kehrbürsten in bezug auf den Maschinenrahmen nicht zu groß wird.With the articulated design of the machine according to the features of claims 3 and 4 it is ensured that the lateral deflection of the sweeping brushes with respect to the machine frame is not too great even in narrow bends.

Die Weiterbildung gemäß Anspruch 5 ermöglicht ein Absenken der Kehrbürste unter Beibehaltung einer waagrechten Lage des Querförderbandes.The development according to claim 5 enables a lowering of the sweeping brush while maintaining a horizontal position of the cross conveyor belt.

Die weitere Ausbildung nach Anspruch 6 und 7 ermöglicht eine Verkleinerung von Schotteranhäufungen, um einen von einer ungleichmäßigen Schotterverteilung weitgehend unabhängigen, gleichmäßigen Kehreffekt zu erzielen.The further embodiment according to claims 6 and 7 enables a reduction in the accumulation of ballast in order to achieve a uniform sweeping effect that is largely independent of an uneven distribution of ballast.

Außerdem ist noch eine weitere vorteilhafte Ausbildung der Erfindung durch die Ansprüche 8 und 9 gekennzeichnet. Mit der unterschiedlichen Ausbildung der Rotationskörper sind die Kehrbürsten optimal zur Einschotterung von unterschiedliche Schwellenarten aufweisenden Gleisabschnitten einsetzbar.In addition, a further advantageous embodiment of the invention is characterized by claims 8 and 9. With the different design of the rotating bodies, the sweeping brushes can be optimally used for the ballasting of track sections with different types of sleepers.

Schließlich hat die Weiterbildung gemäß Anspruch 10 den besonderen Vorteil, daß insbesondere bereits im Einsatz befindliche Schotterpflüge mit einer im gekröpften Rahmenabschnitt befindlichen Kehrbürste mit minimalem konstruktiven Aufwand zur Erzielung der erfindungsgemäßen Vorteile umrüstbar sind.Finally, the development according to claim 10 has the particular advantage that, in particular, ballast plows already in use can be converted with a sweeping brush located in the cranked frame section with minimal design effort to achieve the advantages according to the invention.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben.The invention is described in more detail below with reference to exemplary embodiments shown in the drawing.

Show it:
  • 1 is a side view of a sweeper designed according to the invention for sweeping a track, with three sweeping brushes spaced apart in the longitudinal direction of the machine, the foremost being assigned a conveyor belt and a ballast store,
  • Fig. 2 shows a variant of the sweeper in side view
  • 3 to 5 each in schematic form the outline of a rotating body formed by the sweeping surface of the sweeping brush.

Die in Fig. 1 ersichtliche Kehrmaschine 1 zum Kehren eines Gleises 2 weist einen aus zwei jeweils nach oben gekröpft ausgebildeten Rahmenteilen 3,4 zusammengesetzten Maschinenrahmen 5 auf. Die beiden Rahmenteile 3,4 sind im Bereich eines Schienenfahrwerkes 6 durch eine Gelenkverbindung 7 gelenkig miteinander verbunden und endseitig jeweils über weitere Schienenfahrwerke 8 abgestützt. Dem in Arbeitsrichtung - durch einen Pfeil 9 dargestellt - vorderen bzw. ersten Rahmenteil 3 ist eine erste Kehrbürste 10 mit einem vorgeordneten, in Maschinenlängsrichtung verlaufenden Förderband 11 und einem Schotterspeicher 12 zugeordnet. Dieser befindet sich unterhalb eines Abwurfendes 37 des Förderbandes 11 und ist mit steuerbaren Entladeöffnungen 13 ausgestattet. Diesen ist ein höhenverstellbar am Maschinenrahmen 5 befestigter Planierschild 14 unmittelbar nachgeordnet.The sweeper 1 shown in FIG. 1 for sweeping a track 2 has a machine frame 5 composed of two frame parts 3, 4 which are each cranked upwards. The two frame parts 3, 4 are articulated to one another in the region of a rail undercarriage 6 by means of an articulated connection 7 and are supported at the ends by additional rail undercarriages 8. A first sweeping brush 10 with an upstream conveyor belt 11 running in the machine longitudinal direction and a ballast accumulator 12 is assigned to the front or first frame part 3 in the working direction - represented by an arrow 9. This is located below a discharge end 37 of the conveyor belt 11 and is equipped with controllable unloading openings 13. This is immediately followed by a height-adjustable dozer blade 14 attached to the machine frame 5.

Der hintere bzw. zweite Rahmenteil 4 ist in seinem nach oben gekröpften Abschnitt mit zwei in Maschinenlängsrichtung hintereinander angeordneten Kehrbürsten 15,16 ausgestattet, die ebenso wie die erste Kehrbürste 10 jeweils durch eine allseitig bewegbare Gelenkverbindung 17 mit dem Maschinenrahmen 5 verbunden sind. Diese Gelenkverbindung 17 ist jeweils als Parallelogrammanlenkung ausgebildet, so daß die Position der Kehrbürsten 10,15,16 in bezug auf die Horizontale von der Höhenverstellung durch Antriebe 18 unbeeinflußt ist. Jeder Kehrbürste 10,15,16 ist ein mit einem Antrieb versehenes, quer zur Maschinenlängsrichtung verlaufendes Querförderband 19 unmittelbar vorgeordnet. Außerdem ist einem Tragrahmen 20 der Kehrbürsten 10,15,16 jeweils eine Spurkranzrolle 21 zur Auflage auf dem Gleis 2 zugeordnet.The rear or second frame part 4 is equipped in its cranked section with two sweeping brushes 15, 16 arranged one behind the other in the longitudinal direction of the machine, which, like the first sweeping brush 10, are each connected to the machine frame 5 by a joint connection 17 which can be moved on all sides. This joint 17 is in each case as a parallelogram linkage formed so that the position of the sweeping brushes 10, 15, 16 with respect to the horizontal is unaffected by the height adjustment by drives 18. Each sweeping brush 10, 15, 16 is immediately preceded by a cross conveyor belt 19, which is provided with a drive and runs transversely to the machine longitudinal direction. In addition, a flange 21 is assigned to a supporting frame 20 of the sweeping brushes 10, 15, 16 for resting on the track 2.

Für die Energieversorgung eines Fahrantriebes 22 und der verschiedenen anderen Antriebe ist im Bereich der Gelenkverbindung 7 ein Motor 23 vorgesehen. Am vorderen und hinteren Ende der Kehrmaschine 1 befindet sich jeweils eine Fahrkabine mit einer zentralen Steuereinrichtung 25.A motor 23 is provided in the region of the articulated connection 7 for supplying energy to a travel drive 22 and the various other drives. At the front and rear end of the sweeper 1 there is a driving cabin with a central control device 25.

Im Arbeitseinsatz kann die Anzahl der einzusetzenden Kehrbürsten 10,15 und 16 in Abhängigkeit vom Einschotterungszustand des Gleises 2 variiert werden. In den meisten Fällen werden zweckmäßigerweise alle drei Kehrbürsten 10,15,16 durch Beaufschlagung der Antriebe 18 abgesenkt, bis die Spurkranzrollen 21 auf Schienen 24 des Gleises 2 aufliegen. Dabei ist es insbesondere bei größeren Schottermengen besonders vorteilhaft, wenn die Absenkung der drei Kehrbürsten stufenmäßig erfolgt, so daß die hinterste Kehrbürste 16 am tiefsten abgesenkt wird. Dies ermöglicht einen besonders effizienten Kehreffekt mit einer weitgehenden Schonung der Kehrelemente der vordersten Kehrbürste. Durch Beaufschlagung von Antrieben 26 werden die Kehrbürsten 10,15,16 in Rotation versetzt. Dabei gelangt überschüssiger Schotter auf die vorgeordneten Querförderbänder 19 und von diesen auf die Schotterbettflanken. Falls ein Antrieb 27 des Förderbandes 11 eingeschaltet ist, wird der von der ersten Kehrbürste 10 hochgeförderte überschüssige Schotter mit Hilfe des Förderbandes 11 hochtransportiert und in den vorgeordneten Schotterspeicher 12 abgeworfen. Sobald ein Gleisabschnitt mit zu wenig Schotter erreicht ist, werden die Entladeöffnungen 13 betätigt und gespeicherter Schotter auf das Gleis 2 bedarfsweise abgeworfen. Größere Schotteranhäufungen können zur Erleichterung der Kehrarbeit durch Absenken des Planierschildes 14 planiert werden.During work, the number of sweeping brushes 10, 15 and 16 to be used can be varied depending on the ballast condition of the track 2. In most cases, all three sweeping brushes 10, 15, 16 are expediently lowered by acting on the drives 18 until the flanged rollers 21 rest on rails 24 of the track 2. It is particularly advantageous in the case of larger amounts of ballast if the three sweeping brushes are lowered gradually so that the rearmost sweeping brush 16 is lowered the deepest. This enables a particularly efficient sweeping effect with extensive protection of the sweeping elements of the foremost sweeping brush. By actuating drives 26, the sweeping brushes 10, 15, 16 are set in rotation. Excess ballast gets onto the upstream transverse conveyor belts 19 and from there onto the ballast bed flanks. If a drive 27 of the conveyor belt 11 is switched on, the excess ballast conveyed up by the first sweeping brush 10 is transported up with the aid of the conveyor belt 11 and thrown into the upstream ballast store 12. As soon as a track section with too little ballast is reached, the unloading openings 13 are actuated and stored ballast is thrown onto the track 2 as required. Larger accumulations of ballast can be leveled by lowering the dozer blade 14 to make sweeping easier.

Bei der in Fig. 2 ersichtlichen Kehrmaschine 1 sind die im Vergleich mit der in Fig. 1 beschriebenen Kehrmaschine 1 funktionsgleichen Merkmale mit denselben Bezugszeichen versehen. Abweichend von der oben beschriebenen Kehrmaschine weist der vordere, erste Rahmenteil 3 in seinem hinteren Endbereich einen über das mittlere Schienenfahrwerk 6 vorkragenden und nach oben gekröpften Rahmenabschnitt 28 auf. Dieser ist wiederum endseitig über die Gelenkverbindung 7 mit dem als Trailerrahmen 29 ausgebildeten zweiten Rahmenteil 4 gelenkig verbunden.In the sweeper 1 shown in FIG. 2, the features which are functionally identical in comparison with the sweeper 1 described in FIG. 1 are also included provided the same reference numerals. In a departure from the sweeper described above, the front, first frame part 3 has in its rear end region a frame section 28 which projects beyond the middle rail running gear 6 and is cranked upwards. This is in turn connected in an articulated manner via the hinge connection 7 to the second frame part 4 designed as a trailer frame 29.

Zwischen den beiden Schienenfahrwerken 8,6 des ersten Rahmenteiles 3 ist eine durch Antriebe höhenverstellbare, aus einem Mittelpflug 30 und Flankenpflügen 31 gebildete Pfluganordnung vorgesehen. Diese Kehrmaschine 1 ist bezüglich der Kehrbürsten 10,15,16 und des Schotterspeichers 12 wie zu Fig. 1 beschrieben einsetzbar. Zusätzlich können unmittelbar vor der Kehrung größere Schotterbewegungen mit Hilfe der Schotterpfluganordnung durchgeführt werden, um das Gleis 2 gleichmäßig einzuschottern.Between the two rail carriages 8, 6 of the first frame part 3 there is a plow arrangement which is height-adjustable by drives and which is formed from a center plow 30 and side plows 31. This sweeper 1 can be used with respect to the sweeping brushes 10, 15, 16 and the ballast accumulator 12 as described for FIG. 1. In addition, larger ballast movements can be carried out immediately before the turn with the help of the ballast plow arrangement in order to ballast the track 2 evenly.

Wie in den Fig. 3 bis 5 ersichtlich, können die verschiedenen Kehrbürsten 10,15,16 (die der besseren Darstellung wegen von den Schwellen geringfügig distanziert dargestellt sind) bezüglich ihrer durch die Stirnflächen 38 von Kehrelementen 32 gebildeten Rotationskörper 33 (teilweise in strichpunktierten Linien dargestellt) unterschiedlich ausgebildet sein. Der in Fig. 3 dargestellte, zylindrisch ausgebildete Rotationskörper 33 eignet sich vor allem zum Kehren von Schwellen 34 aus Holz. Der Rotationskörper 33 gemäß Fig. 4 ist besonders zum Kehren von Schwellen 34 aus Beton geeignet. Der in Fig. 5 in Verbindung mit einer Zweiblockschwelle dargestellte Rotationskörper 33 weist einen Mittelteil 35 auf, der mit im Vergleich zu den angrenzenden Bürstenabschnitten 36 längeren Kehrelementen 32 ausgestattet ist. Damit ist insbesondere für Hochgeschwindigkeitsstrecken die Möglichkeit gegeben, den Schotter im Bereich zwischen den Schienen tiefer als in den restlichen Bereichen aus dem Schwellenfach herauszukehren. Eine Rotationswelle 39 ist schematisch mit strichpunktierten Linien angedeutet. Selbstverständlich ist jede andere Kombination von unterschiedlich ausgebildeten Rotationskörpern 33 möglich.As can be seen in FIGS. 3 to 5, the various sweeping brushes 10, 15, 16 (which are shown slightly distanced from the thresholds for the sake of better illustration) can be rotated (partly in dash-dotted lines) with respect to their rotating bodies 33 formed by the end faces 38 of sweeping elements 32 shown) can be designed differently. The cylindrically shaped rotary body 33 shown in FIG. 3 is particularly suitable for sweeping sleepers 34 made of wood. 4 is particularly suitable for sweeping sleepers 34 made of concrete. The rotary body 33 shown in FIG. 5 in connection with a two-block sleeper has a central part 35 which is equipped with sweeping elements 32 which are longer in comparison to the adjacent brush sections 36. This enables the ballast in the area between the rails to come out of the sleeper compartment deeper than in the remaining areas, especially for high-speed lines. A rotation shaft 39 is indicated schematically with dash-dotted lines. Of course, any other combination of differently designed rotating bodies 33 is possible.

Für einen leistungsfähigen Arbeitseinsatz in Hochgeschwindigkeitsstrecken ist es besonders vorteilhaft, wenn die in Arbeitsrichtung erste Kehrbürste 10 der Kehrmaschine 1 gemäß Fig. 3 ausgebildet ist, um vorerst gegebenenfalls vorhandene größere Schottermengen wegzukehren. Die mittlere und letzte Kehrbürste 15 bzw. 16 sind zweckmäßiger bereits gemäß Fig. 5 ausgebildet, um den Schotter aus dem Gleismittelbereich vorschriftsmäßig tiefer auszukehren.For efficient work in high-speed lines, it is particularly advantageous if the first sweeping brush 10 of the sweeper 1 according to FIG. 3 is designed to initially, if necessary to sweep away existing larger amounts of ballast. The middle and last sweeping brushes 15 and 16 are more appropriately designed according to FIG. 5, in order to sweep the ballast deeper out of the area of the track center.

Eine vorteilhafte Einsatzvariante der Kehrmaschine 1 besteht auch darin, daß beispielsweise die erste bzw. ersten beiden Kehrbürsten 10 bzw. 10,15 einen zylindrischen Rotationskörper 33 gemäß Fig. 3 aufweisen, während die letzte Kehrbürste 16 besonders zur Kehrung von Betonschwellen gemäß Fig. 4 ausgebildet ist. Diese Variante eignet sich besonders zum Kehren von Gleisabschnitten, die sich aus Teilbereichen mit unterschiedlichen Schwellen aus Holz und Beton zusammensetzen. In einem derartigen Fall kann dann die jeweils zweckmäßigste Kehrbürste, gegebenenfalls auch in Kombination mit einer weiteren, anders ausgebildeten Kehrbürste, eingesetzt werden.An advantageous application variant of the sweeper 1 also consists in the fact that, for example, the first and first two sweeping brushes 10 and 10, 15 have a cylindrical rotating body 33 according to FIG. 3, while the last sweeping brush 16 is especially designed for sweeping concrete sleepers according to FIG. 4 is. This variant is particularly suitable for sweeping track sections that are made up of sections with different sleepers made of wood and concrete. In such a case, the most appropriate sweeping brush can then be used, possibly also in combination with a further, differently designed sweeping brush.
