Description

Die Erfindung bezieht sich auf eine Querverteilanordnung für einen Straßenfertiger.The invention relates to a transverse distribution arrangement for a paver.

Solche Querverteilanordnungen sind beispielsweise aus der EP 1 120 495 A1 bekannt, welche eine Querverteilanordnung gemäß der Präambel des Anspruchs 1 zeigt. Sie sind am hinteren Ende des Chassis des Straßenfertigers befestigt, nämlich zwischen dem Chassis und einer von dem Chassis geschleppten Einbaubohle. Einbaumaterial, beispielsweise bituminöses Einbaumischgut, wird mittels eines Längsförderers, auch Kratzerband genannt, auf die Querverteilanordnung gefördert. Diese hat die Aufgabe, das Einbaumischgut in Querrichtung des Straßenfertigers zu verteilen, so dass das Einbaumaterial über die gesamte Breite der nachfolgenden Einbaubohle zur Verfügung steht. Zu diesem Zweck verfügt die Querverteilanordnung über zwei Verteilerschnecken, nämlich eine linke und eine rechte Verteilerschnecke. Die beiden Verteilerschnecken sind gegenläufig zueinander in dem Sinne, dass sie das angelieferte Einbaumischgut jeweils von der Mitte des Straßenfertigers zu seinen Außenseiten transportieren. Diese Gegenläufigkeit der Verteilerschnecken kann durch gegenläufige Steigungen ihrer Gewinde erzielt werden, so dass die Verteilerschnecken weiterhin eine gemeinsame Welle und eine gemeinsame Drehrichtung haben können. Zudem können sie dabei weiterhin durch einen gemeinsamen Schneckenantrieb angetrieben sein.
Wegen der erheblichen Kräfte sind die äußeren Enden der Verteilerschnecken üblicherweise nicht frei gelagert, sondern jeweils in einer Schneckenlagerkonsole. Wegen des gegen diese Konsolen geförderten Einbaumaterials entsteht an den Schneckenlagerkonsolen ein erheblicher abrasiver Verschleiß. Um die Standzeit der Schneckenlagerkonsolen zu erhöhen, ist es bekannt, auf deren Innenseite Verschleißbleche aufzusetzen, die in bestimmten Intervallen ausgetauscht werden müssen.
Aus der DE 20 2006 014 704 U1 geht eine Schneckenfördereinrichtung für den Untertage-Bergbau hervor, die nichts mit Straßenfertigern oder der Förderung von Einbaumaterial an einem Straßenfertiger zu tun hat.
Aufgabe der vorliegenden Erfindung ist es, die bekannte Querverteilanordnung für einen Straßenfertiger hinsichtlich eines geringeren Wartungsaufwands zu verbessern.Such transverse distribution arrangements are for example from the EP 1 120 495 A1 which discloses a transverse distribution arrangement according to the preamble of claim 1. They are attached to the rear end of the chassis of the paver, namely between the chassis and a screed towed by the chassis. Installation material, such as bituminous Einbaumischgut, is promoted by means of a longitudinal conveyor, also called scraper belt on the transverse distribution arrangement. This has the task of distributing the Einbaumischgut in the transverse direction of the paver, so that the paving material over the entire width of the subsequent screed is available. For this purpose, the transverse distribution arrangement has two distributor screws, namely a left and a right distribution screw. The two distributor screws are in opposite directions in the sense that they transport the delivered built-in material in each case from the center of the paver to its outer sides. This counterrotation of the distributor screws can be achieved by opposing pitches of their threads, so that the distributor screws can continue to have a common shaft and a common direction of rotation. In addition, they can continue to be driven by a common worm drive.
Because of the considerable forces, the outer ends of the auger usually are not stored freely, but each in a screw storage console. Because of the built-in against these consoles mounting material is created on the screw bearing consoles a significant abrasive wear. In order to increase the service life of the screw bearing consoles, it is known to put on the inside of wear plates, which must be replaced at certain intervals.
From the DE 20 2006 014 704 U1 goes out a screw conveyor for underground mining, which has nothing to do with road pavers or the promotion of paving material on a paver.
Object of the present invention is to improve the known transverse distribution arrangement for a paver with respect to a lower maintenance cost.

Diese Aufgabe wird gelöst durch eine Querverteilanordnung für einen Straßenfertiger mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a transverse distribution arrangement for a paver with the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Die erfindungsgemäße Querverteilanordnung zum Quer-Verteilen von Einbaumaterial an einem Straßenfertiger sieht vor, dass jede Schneckenlagerkonsole zum Lagern einer Welle der ihr zugeordneten Verteilerschnecke ein geschlossenes Rohr aufweist, das mindestens teilweise aus verschleißfestem Stahl gefertigt ist. Als "verschleißfester Stahl" wird im Sinne der Erfindung Stahl mit einer Härte von mindestens 300 HBW definiert. Vorzugsweise liegt die Härte des für die Erfindung verwendeten, verschleißfesten Stahls jedoch bei mindestens 400 oder sogar bei über 500 HBW. Besonders gut eignet sich als verschleißfester Stahl ein Stahl, der unter dem Handelsnamen Hardox verfügbar ist.The transverse distribution arrangement according to the invention for the transverse distribution of installation material on a paver provides that each screw storage console for supporting a shaft of its associated auger has a closed tube which is at least partially made of wear-resistant steel. For the purposes of the invention, "wear-resistant steel" is defined as steel having a hardness of at least 300 HBW. Preferably, however, the hardness of the wear resistant steel used in the invention is at least 400 or even more than 500 HBW. A steel which is available under the trade name Hardox is particularly suitable as a wear-resistant steel.

Als vorteilhaft hat es sich erwiesen, wenn das Rohr vollständig aus verschleißfestem Stahl gefertigt ist, da dies den Verschleiß weiter vermindert und die Wartungsintervalle entsprechend verlängert.It has proven to be advantageous if the tube is made entirely of wear-resistant steel, as this further reduces wear and extends the maintenance intervals accordingly.

Erfindungsgemäß ist das Rohr aus zwei Halbschalen zusammengesetzt. Dabei kann das Zusammensetzen der beiden Halbschalen beispielsweise dann erfolgen, wenn bereits die Welle einer Verteilerschnecke in eine der beiden Halbschalen eingelegt ist. Bei dieser Konfiguration wäre es möglich, dass beide Halbschalen aus demselben verschleißfesten Stahl gefertigt sind. Alternativ wäre es jedoch auch möglich, dass die beiden Halbschalen aus unterschiedlichem Material gefertigt sind, wobei es insbesondere genügen würde, wenn nur die der Schneckenaufhängung zugewandte Halbschale aus besonders verschleißfestem Stahl gefertigt ist.According to the invention, the tube is composed of two half-shells. In this case, the assembly of the two half-shells, for example, take place when already the shaft of a distribution screw is inserted into one of the two half-shells. With this configuration, it would be possible for both shells to be made of the same wear-resistant steel. Alternatively, it would also be possible that the two half-shells are made of different materials, in which case it would be sufficient in particular if only the half-shell facing the helical suspension is made of particularly wear-resistant steel.

Denkbar wäre es, die beiden Halbschalen lösbar miteinander zu verbinden. Dies würde es ermöglichen, die besonders stark von Verschleiß belastete Halbschale als Verschleißteil nach einer gewissen Betriebsdauer auszutauschen.It would be possible to detachably connect the two half-shells together. This would make it possible to exchange the particularly heavily loaded by wear half shell as a wearing part after a certain period of operation.

Alternativ dazu könnten die beiden Halbschalen jedoch auch fest miteinander verbunden werden. Beispielsweise könnte dies durch ein Verschweißen der beiden Halbschalen miteinander erfolgen.Alternatively, however, the two half-shells could also be firmly connected. For example, this could be done by welding the two shells together.

Besondere Vorteile bietet die Erfindung, wenn die beiden in der Querverteilanordnung verwendeten Schneckenlagerkonsolen identisch zueinander ausgebildet sind. Diese Identität kann sich nicht nur auf die beiden Rohre beziehen, sondern auch Befestigungsbleche zum Befestigen der Querverteilanordnung an dem Chassis des Straßenfertigers umfassen. Durch die Ausbildung der beiden Schneckenlagerkonsolen als identische Teile bzw. Gleichteile verringert sich der Aufwand für die Lagerhaltung erheblich, da nicht mehr zwei unterschiedliche Schneckenlagerkonsolen hergestellt und gelagert werden müssen. Zudem können Probleme wie die Rücksendung unpassender linker oder rechter Schneckenlagerkonsolen vermieden werden.The invention offers particular advantages if the two screw bearing consoles used in the transverse distribution arrangement are identical to one another. This identity can not only refer to the two tubes, but also include mounting plates for securing the transverse distribution arrangement to the chassis of the paver. Through the training the two screw storage consoles as identical parts or identical parts significantly reduces the cost of storage, since no longer need to be manufactured and stored two different screw storage consoles. In addition, problems such as the return of improper left or right screw storage consoles can be avoided.

Die Wartungsintervalle der Querverteilanordnung können weiter dadurch verlängert werden, dass wenigstens eine Oberfläche des Rohrs gehärtet ist und/oder dass wenigstens eine Oberfläche des Rohrs mit einer verschleißmindernden Beschichtung versehen ist.The maintenance intervals of the transverse distribution arrangement can be further extended by hardening at least one surface of the tube and / or providing at least one surface of the tube with a wear-reducing coating.

Die Erfindung bezieht sich schließlich auch auf einen Straßenfertiger mit einer Querverteilanordnung für Einbaumischgut gemäß einer der vorstehend beschriebenen Ausführungsvarianten.The invention finally also relates to a paver with a transverse distribution arrangement for built-in material according to one of the embodiments described above.

Die einzige Figur zeigt in perspektivischer Ansicht ein Ausführungsbeispiel einer erfindungsgemäßen Querverteilanordnung 1. Diese Querverteilanordnung 1 ist am rückseitigen Ende des Chassis 2 eines Straßenfertigers befestigt.The sole FIGURE shows a perspective view of an embodiment of a transverse distribution arrangement 1 according to the invention. This transverse distribution arrangement 1 is fastened to the rear end of the chassis 2 of a road finisher.

Die Querverteilanordnung 1 umfasst eine (in Fahrtrichtung des Straßenfertigers) rechte Verteilerschnecke 3 sowie eine linke Verteilerschnecke 4. Beide Verteilerschnecken 3, 4 sind mittig an einer Schneckenaufhängung 5 gelagert. In dem von der Schneckenaufhängung 5 gebildeten Gehäuse befindet sich ein Schneckenantrieb (nicht dargestellt) zum Antreiben der beiden Verteilerschnecken 3, 4.The transverse distribution arrangement 1 comprises a right-hand distribution screw 3 (in the direction of travel of the road paver) and a left-hand distribution screw 4. Both distribution screws 3, 4 are mounted centrally on a screw suspension 5. In the housing formed by the worm suspension 5 is a worm drive (not shown) for driving the two distribution screws 3, 4th

Jede Verteilerschnecke 3, 4 verfügt über eine Welle 6. Dabei kann es sich um zwei einzelne Wellen 6 oder um eine gemeinsame Welle 6 der beiden Verteilerschnecken 3, 4 handeln. Das äußere, also der Schneckenaufhängung 5 abgewandte Ende 6a jeder Welle 6 ist in einem Schneckenlager 7 gelagert. Jedes Schneckenlager 7 ist am unteren Ende einer Schneckenlagerkonsole 8 montiert. Diese Schneckenlagerkonsolen 8 weisen dabei ein im Wesentlich vertikal ausgerichtetes Rohr 9 auf, das mittels einer Befestigungsplatte 10 am Chassis 2 des Straßenfertigers befestigt ist. Das Rohr 9 ist jeweils aus verschleißfestem Stahl gefertigt und hat vorzugsweise eine gehärtete oder mit einer verschleißmindernden Beschichtung versehene Außenseite.Each distributor screw 3, 4 has a shaft 6. These may be two individual shafts 6 or a common shaft 6 of the two distributor screws 3, 4. The outer end 6a of each shaft 6, that is remote from the worm suspension 5, is mounted in a worm bearing 7. Each worm bearing 7 is mounted at the lower end of a worm bearing bracket 8. These screw bearing brackets 8 in this case have a substantially vertically aligned tube 9, which is fastened by means of a mounting plate 10 on the chassis 2 of the paver. The tube 9 is made of wear-resistant steel and preferably has a hardened or provided with a wear-reducing coating outside.

Jedes Rohr 9 ist aus zwei Halbschalen 9a, 9b zusammengesetzt. Jede der Halbschalen 9a, 9b kann halbkreisförmig ausgebildet sein, so dass sich die beiden Halbschalen zu einem Rohr 9 mit kreisförmigem Durchmesser zusammensetzen. Die beiden Halbschalen 9a, 9b können miteinander verschweißt sein.Each tube 9 is composed of two half-shells 9a, 9b. Each of the half-shells 9a, 9b may be semicircular, so that the two half-shells are assembled into a tube 9 with a circular diameter. The two half shells 9a, 9b can be welded together.

Im vorliegenden Ausführungsbeispiel sind die beiden Schneckenlagerkonsolen 8 als Gleichteile ausgebildet, das heißt sie sind identisch zueinander ausgebildet. Dies bezieht sich nicht nur auf die Rohre 9, sondern auch auf die jeweils zugeordneten Befestigungsplatten 10.In the present embodiment, the two screw bearing consoles 8 are formed as identical parts, that is, they are identical to each other. This refers not only to the tubes 9, but also to the respective associated mounting plates 10th

Im Betrieb fördern die Verteilerschnecken 3, 4 Einbaumischgut zu den Außenseiten des Straßenfertigers, insbesondere zu den Schneckenlagerkonsolen 8.During operation, the distributor screws 3, 4 convey built-in mixes to the outer sides of the road paver, in particular to the screw bearing consoles 8.
