Abstract

The road roller (1) is a self-propelled machine with a cylindrical roller (3) at the leading end to compress the road surface material, such as of gravel or sand. A plate unit (7) is at the trailing end to smooth and compress the road surface, to ensure that the upper layers of the road surface are consistently compacted. The trailing smoothing/compressing unit (7) is operated by a hydraulic pump (10) with an oil motor (8) at variable rotary speeds. The trailing unit (7) has a height adjustment (6), and a setting mechanism (11) to alter the gap between it and the roller (3).

Description

Die Erfindung betrifft eine Straßenwalze mit einer zylindrischen Walze zum Verdichten von rolligem Material wie Kies oder Sand.The invention relates to a road roller with a cylindrical Roller for compacting rolling material such as Gravel or sand.

Bei bekannten Straßenwalzen mit einer zylindrischen Walze bestehen derzeit Probleme beim Verdichten von rolligem Material, wie zum Beispiel Kies oder Sand. Diese entstehen dadurch, dass durch die zylindrische Walze beim dynamischen Verdichten die Verdichterwellen schräg in das zu verdichtende Material gelangen. Dadurch ergibt sich zwar eine gute Verdichtung des Materials in der Tiefe, jedoch nimmt diese Verdichtung näher zur Oberfläche des Materials hin unerwünscht stark ab, da sich in diesem Bereich das zu verdichtende Material während des Verdichtungsvorganges von der Walze weg verschiebt.In known road rollers with a cylindrical roller there are currently problems with compacting rolling Material such as gravel or sand. These arise by the fact that the cylindrical roller with dynamic Compress the compressor shafts obliquely into that compacting material. This does indeed result a good compaction of the material in depth, however takes this compaction closer to the surface of the material towards undesirably strongly, because in this area the material to be compressed during the compression process moved away from the roller.

Der Erfindung liegt das Problem zugrunde, eine Straßenwalze der eingangs genannten Art so zu gestalten, dass sich mit ihr eine gute Verdichtung bis hin zur Oberfläche des zu verdichtenden Belags ergibt.The invention is based on the problem of a road roller of the type mentioned at the beginning so that with it a good compaction up to the surface of the covering to be compacted.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Walze ein Plattenverdichter in Fahrtrichtung der Walze nachgeschaltet ist.This problem is solved according to the invention in that the roller is a plate compactor in the direction of travel Roller is connected.

Durch diese Kombination zweier an sich bekannter Verdichtungsmittel erreicht man durch die zylindrische Walze eine gute Tiefenwirkung der Verdichtung und durch den nachgeschalteten Plattenverdichter eine hohe Verdichtung bis zur Oberfläche des zu verdichtenden Belags. Zugleich lässt sich durch die dynamische Wirkung des Plattenverdichters eine Entmischung des zu verdichtenden Materials vermeiden, so dass Kleinkornanteile nicht mehr nach oben wandern, was beim Verdichten ausschließlich mit einer Walze und mehreren Übergängen, also mit mehrmaligem Überfahren des zu verdichtenden Bereiches, der Fall ist.Through this combination of two compression means known per se can be reached through the cylindrical roller a good depth effect of the compression and through the downstream plate compressors a high compression to the surface of the covering to be compacted. At the same time can be achieved through the dynamic effect of the plate compressor segregation of the material to be compacted avoid so that small grain portions no longer up hike what when compacting only with one Roller and several transitions, that is with multiple passes of the area to be compressed, which is the case.

Für unterschiedliche Materialien sind unterschiedliche Schwingungsfrequenzen des Plattenverdichters optimal. Eine Anpassung an verschiedene Materialien wird auf einfache Weise möglich, wenn gemäß einer Weiterbildung der Erfindung der Plattenverdichter von einer Hydraulikpumpe über einen Ölmotor in der Drehzahl veränderlich angetrieben ist.Different materials are different Vibration frequencies of the plate compressor optimal. An adaptation to different materials is easy Way possible if, according to a training of Invention of the plate compressor from a hydraulic pump Variable speed driven by an oil motor is.

Die Verdichtungswirkung lässt sich auf einfache Weise verstellen, wenn gemäß einer anderen Weiterbildung der Erfindung der Plattenverdichter an einem mittels einer Verstelleinrichtung höhenverstellbaren Geräteträger vertikal verstellbar angeordnet ist.The compaction effect can be done easily adjust if according to another training the Invention of the plate compressor on a means of Adjustment device vertically adjustable equipment carrier is adjustable.

Der Plattenverdichter vermag seitlich zur Walze liegende Bereiche zu erreichen, wenn er an dem Geräteträger durch eine Verstelleinrichtung in Längsrichtung der Walze verstellbar angeordnet ist.The plate compactor can lie to the side of the roller Reach areas when he is through on the equipment rack an adjustment device adjustable in the longitudinal direction of the roller is arranged.

Die Erfindung lässt verschiedene Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon schematisch in der Zeichnung dargestellt und wird nachfolgend beschrieben. Die Zeichnung zeigt in

The invention permits various embodiments. To further clarify its basic principle, one of them is shown schematically in the drawing and is described below. The drawing shows in
Fig. 1
a side view of the road roller according to the invention,
Fig. 2
a schematic representation of the operation of the road roller.

Die Figur 1 zeigt eine Straßenwalze 1, welche als selbstfahrendes Fahrzeug ausgebildet ist und einen Rahmen 2 aufweist. In Fahrtrichtung an der Vorderseite der Straßenwalze 1 ist eine zylindrische Walze 3 am Rahmen 2 befestigt. An der Rückseite der Straßenwalze 1 ist am Rahmen 2 ein Geräteträger 4 um eine Achse 5 schwenkbar befestigt, der mittels einer Verstelleinrichtung 6 verschwenkt werden kann und einen Plattenverdichter 7 trägt. Dieser Plattenverdichter 7 hat einen Ölmotor 8, dem über eine Leitung 9 Öl von einer in der Straßenwalze 1 angeordneten Hydraulikpumpe 10 zugeführt werden kann. Dadurch lässt sich die Schwingungsfrequenz des Plattenverdichters 7 verstellen. Die Verstelleinrichtung 6 ermöglicht es, durch mehr oder weniger starkes Anheben des Plattenverdichters 7 seine Verdichtungswirkung zu verändern. Weiterhin kann er durch Abheben von der zu verdichtenden Oberfläche in eine Ruhestellung gebracht werden.Figure 1 shows a road roller 1, which as a self-propelled Vehicle is formed and a frame 2nd having. In the direction of travel at the front of the road roller 1, a cylindrical roller 3 is attached to the frame 2. At the back of the road roller 1 is on the frame 2 a device carrier 4 fastened pivotably about an axis 5, which is pivoted by means of an adjusting device 6 can be and carries a plate compressor 7. This plate compressor 7 has an oil motor 8, the over a line 9 of oil arranged in the road roller 1 Hydraulic pump 10 can be supplied. Thereby the vibration frequency of the plate compressor 7 adjust. The adjustment device 6 enables by lifting the plate compactor more or less 7 to change its compacting effect. Farther it can be compressed by lifting it off Surface be brought into a rest position.

Eine Verstelleinrichtung 11 am freien Ende des Geräteträgers 4 erlaubt eine Verschiebung des Plattenverdichters 7 quer zur Zeichnungsebene, also in Richtung der Drehachse der Walze 3. Dadurch kann der Plattenverdichter 7 beispielsweise seitlich über die Walze 3 hinausragen, so dass auch Bereiche erreichbar sind, welche nicht von der Walze 3 befahren werden.An adjusting device 11 at the free end of the device carrier 4 permits displacement of the plate compressor 7 transverse to the plane of the drawing, i.e. in the direction of the axis of rotation the roller 3. This allows the plate compactor 7, for example protrude laterally beyond the roller 3, see above that areas that are not accessible by the Roll 3 are driven.

Die Figur 2 verdeutlicht, wie es zu der Verdichtung eines Belags 12 kommt. Verdeutlicht wird, dass die Walze 3, welche sich mit dem Plattenverdichter 7 in der Zeichnung gesehen nach rechts bewegt, den Belag 12 nach unten in die Tiefe gehend stark verdichtet und nahe der Oberfläche diese Verdichtung abnimmt. Diese in der Nähe der Oberfläche geringere Verdichtung wird durch den nachgeführten Plattenverdichter 7 nachverdichtet. Hierzu hat der Plattenverdichter 7 zwei als Exzenterwellen ausgebildete, gegensinnig angetriebene Erregerwellen 13, 14. Das führt zu einer Addition der Massenkräfte und damit zu einer wirkungsvollen Verdichtung in senkrechter Richtung. Die durch den sogenannten "Bugwelleneffekt" der zylindrischen Walze 3 entstandene, schlechtere Verdichtung im oberen Bereich wird somit durch den Plattenverdichter 7 korrigiert.FIG. 2 illustrates how the compression of a Pad 12 is coming. It is shown that the roller 3, which is with the plate compressor 7 in the drawing seen to the right, the pad 12 down in deeply compacted and close to the surface this compression decreases. This near the surface less compression is made possible by the tracked Plate compressor 7 post-compressed. For this, the plate compressor has 7 two designed as eccentric shafts, in opposite directions driven exciter shafts 13, 14. This leads to an addition of the mass forces and thus to an effective one Compression in the vertical direction. The through the so-called "bow wave effect" of the cylindrical Roll 3 created, poorer compaction in the upper The area is thus corrected by the plate compressor 7.

Durch die Erfindung wird mit einem einmaligen Durchgang der Straßenwalze 1 mit dem nachgeführten Plattenverdichter 7 eine gleichmäßige und meist ausreichende Verdichtung möglich. Dabei kann der Verdichtungsvorgang in der Hälfte der sonst üblichen Zeit stattfinden oder aber die Verdichtungsleistung wird auf das Doppelte erhöht und gleichzeitig der Energieverbrauch gesenkt. Somit können Beläge 12 in guter Qualität zu günstigen Bedingungen hergestellt werden. In der Praxis hat es sich als zweckmäßig erwiesen, dass hinter der Walze 3 je nach ihrer Breite zwei oder drei Plattenverdichter 7 nebeneinander angeordnet werden, die jeweils einen Ölmotor 8 aufweisen. The invention is a one-time pass the road roller 1 with the tracked plate compactor 7 an even and usually sufficient compression possible. The compression process in the Half of the usual time or the Compaction performance is doubled and reduced energy consumption at the same time. So you can Rubbers 12 made in good quality on favorable terms become. In practice, it has proven to be useful proved that behind the roller 3 depending on its width two or three plate compressors 7 arranged side by side are, each having an oil motor 8.
