Technisches Gebiet Technical area

Die Erfindung bezieht sich auf eine Gleisschotterplaniervorrichtung mit einem auf Schienenfahrwerken verfahrbaren Maschinenrahmen, dem eine relativ zum The invention relates to a track ballast planing device with a machine frame which can be moved on rail bogies and which is one relative to the

Maschinenrahmen verstellbare Planiereinrichtung und eine relativ zum Machine frame adjustable leveling device and one relative to the

Maschinenrahmen verstellbare Kehreinrichtung zugeordnet sind, wobei die Machine frame adjustable sweeping device are assigned, the

Planiereinrichtung einen Mittelpflug und zwei Flankenpflüge und die Leveling device a center plow and two flank plows and the

Kehreinrichtung eine drehangetriebene Schotterkehrbürste zum Abkehren von Gleisschotter aufweist und wobei dem Maschinenrahmen gegebenenfalls eine der Schotterkehrbürste zugeordnete Schotterfördereinrichtung und ein Schottersilo mit Einschotterhosen zur Einschotterung des Gleises zugeordnet sind. Sweeping device has a rotary-driven ballast sweeping brush for sweeping track ballast and the machine frame optionally being assigned a ballast conveyor device assigned to the ballast sweeping brush and a ballast silo with ballast trousers for ballasting the track.

Stand der Technik State of the art

Aus der US 5 402 547 ist eine derartige Gleisschotterplaniervorrichtung zum Einschottern eines Gleises bekannt. Einem durch Antriebe höhenverstellbaren und unterhalb des Maschinenrahmens angeordneten Schotterpflug sind insgesamt drei voneinander distanzierte Kehrbürstengehäuse mit jeweils einer drehangetriebenen Kehrbürste nachgeordnet. Am vorderen Ende des Maschinenrahmens befindet sich eine weitere Kehrbürste für einen Austausch gegen eine durch den Such a track ballast leveling device for ballasting a track is known from US Pat. No. 5,402,547. A ballast plow, which is height-adjustable by drives and is arranged below the machine frame, is followed by a total of three spaced-apart sweeping brush housings, each with a rotating sweeping brush. At the front end of the machine frame there is another sweeping brush which can be exchanged for one with the

Arbeitseinsatz im Kehrbürstengehäuse abgenützten Kehrbürste. Der dafür notwendige manipulative Aufwand ist relativ groß, da die eine große Anzahl von elastischen Schläuchen aufweisende Kehrbürste entsprechend schwer ist. Für den Fall, dass das befahrene Gleis zwischen zwei Nachbargleisen liegt, die uneingeschränkt befahren werden, ergeben sich in Verbindung mit dem Working in the sweeping brush housing worn sweeping brush. The manipulative effort required for this is relatively great, since the sweeping brush, which has a large number of elastic hoses, is correspondingly heavy. In the event that the track being used lies between two neighboring tracks that are used without restriction, this results in connection with the

Austausch der Kehrbürste gravierende Sicherheitsprobleme. Die AT 395 875 offenbart eine Kehrvorrichtung, die aus drei separaten, in Replacing the sweeping brush serious safety problems. AT 395 875 discloses a sweeping device which consists of three separate, in

Gleisquerrichtung nebeneinander angeordneten und individuell zum Gleis absenkbaren Kehrbürsten besteht. There are sweeping brushes that are arranged side by side and can be individually lowered to the track.

Die bekannten Kehrbürsten haben eine Vorzugsarbeitsrichtung. Während der Mittelpflug von Gleisschotterplaniervorrichtungen so ausgeführt werden kann, dass er in beide Arbeitsrichtungen funktioniert, gilt das für die Kehrbürsten nicht. The known sweeping brushes have a preferred working direction. While the center plow of ballast leveling devices can be designed to work in both working directions, the sweeping brushes cannot.

Aus EP 2 775 035 sind Gleisschotterplaniervorrichtungen bekannt, die über eine Schotterkehreinrichtung, ein Steilförderband und einen Schottersilo verfügen. From EP 2 775 035 track ballast planing devices are known which have a ballast sweeping device, a steep conveyor belt and a ballast silo.

EP 0 787 858 beschreibt zum leichteren Tausch der Kehrbürste zwei in EP 0 787 858 describes two inches for easier replacement of the sweeping brush

Maschinenquerrichtung voneinander distanzierte und mit dem Maschinenrahmen verbundene Lagerarme zur Abstützung der Bürstenwelle aufweisende Cross-machine direction spaced from one another and having bearing arms connected to the machine frame to support the brush shaft

Haltevorrichtungen zur Zwischenlagerung der Bürstenwelle. Die Haltevorrichtung ist querverschiebbar gelagert und mit einem Querschiebeantrieb verbunden. Damit verschiedene Abkehrvorschriften erfüllt werden können, werden bis zu drei unterschiedliche bestückte Kehrbürsten mit der Maschine mitgeführt. Es unterscheiden sich diese nach der Art der Schwellen. Außerdem wird auf Holding devices for temporary storage of the brush shaft. The holding device is mounted so that it can be displaced transversely and is connected to a transverse slide drive. Up to three different equipped sweeping brushes are carried with the machine so that various sweeping regulations can be met. These differ according to the type of sleepers. It will also be on

Hochgeschwindigkeitsstrecken der Schotter zwischen den Schwellen tiefer ausgekehrt, damit es nicht zu Schotterverwirbelungen und Losschlagen von Schotter aus dem Zwischenfach durch losbrechendes Eis von den Zügen bei Winterbetrieb kommt. High-speed sections of the ballast between the sleepers swept deeper so that there is no ballast turbulence and ballast knocking out of the intermediate compartment due to breaking ice from the trains during winter.

Der Tausch von Kehrbürsten ist bei den bekannten Vorrichtungen aufwändig, da Antriebe abgebaut, die Kehrwelle gelöst und aus dem Kehrwellengehäuse entnommen und gegen eine andere getauscht werden müssen. Erschwerend kommt hinzu, dass die Kehrwelle schwer ist und der Tausch viel Zeit in Anspruch nimmt. The exchange of sweeping brushes is complex in the known devices, since drives have to be dismantled, the sweeping shaft detached and removed from the sweeping shaft housing and exchanged for another. To make matters worse, the turning wave is difficult and the exchange takes a lot of time.

Gleisschotterplaniervorrichtungen müssen ein Gleis je nach Instandhaltungsarbeit mehrfach Einschottern und den Schotter planieren. Abschließend muss das vorgegebene Schotterprofil hergestellt und der Schotter von den Schwellen abgekehrt werden. Da die derzeitigen Schotterkehrbürsten nur in einer Track ballast leveling devices have to ballast a track several times depending on the maintenance work and level the ballast. Finally, the specified ballast profile must be created and the ballast from the sleepers be turned away. Since the current gravel sweeping brushes only come in one

Arbeitsrichtung kehren können, muss die Maschine zum Abschluss der Arbeit zurücksetzen und die Schlussplanie mit Abkehren durchführen. Könnte in beide Richtungen gekehrt werden, dann würde Zeit eingespart und die Arbeit effizienter und kostengünstiger durchgeführt werden. In order to be able to reverse the direction of work, the machine must reverse at the end of the work and carry out the final leveling with sweeping. If it could be turned both ways, time would be saved and the work could be done more efficiently and cheaply.

Arbeiten im Gleis sind durch immer kürzere Sperrpausen gekennzeichnet. Liegen bei einer Instandhaltungsarbeit Holzschwellenabschnitte und Work on the track is characterized by increasingly shorter pauses. Are wooden sleeper sections and during maintenance work

Betonschwellenabschnitte hintereinander, dann ist jeweils die Kehrbürste zu tauschen. Dazu fehlt oft die Zeit, weshalb in so einem Fall ein derartiges Gleis nicht in einer Schicht bearbeitet werden kann. Concrete sleeper sections one behind the other, then the sweeping brush has to be exchanged. There is often not enough time for this, which is why such a track cannot be worked on in one shift in such a case.

Die Kehrbürstengehäuse sind gegen Verschleiß durch wechselbare The sweeping brush housings are interchangeable against wear

Verschleißplatten geschützt. Sind diese abgenutzt, dann sind sie zu tauschen. Dies ist wegen der erschwerten Zugänglichkeit des Inneren des Wear plates protected. If these are worn out, they must be exchanged. This is because of the difficult accessibility of the interior of the

Kehrbürstengehäuses vor Ort nur sehr schwer möglich. Brush housing on site is very difficult.

Nach einer vorteilhaften Weiterbildung der Erfindung soll das Kehren in beide Fahrtrichtungen der Gleisschotterplaniervorrichtung möglich sein. To create sweeping brush that allows an advantageous change of the gravel sweeping brush. According to an advantageous development of the invention, it should be possible for the track ballast leveling device to sweep in both directions of travel.

Die Erfindung löst die gestellte Aufgabe dadurch, dass die Schotterkehrbürste in einem Kehrbürstengehäuse drehangetrieben gelagert ist, das mit einer The invention solves the problem in that the gravel sweeping brush is rotatably mounted in a sweeping brush housing, which with a
