Abstract
Description
Die Erfindung betrifft eine Arbeitsmaschineneinheit, insbesondere zum Einbau und zum Verdichten von Straßenbelagsschichten, sowie ein Verfahren zur Montage der Arbeitsmaschine.The invention relates to a working machine unit, in particular for installation and compaction of paving layers, and a method for assembling the working machine.
Starßenbelagschichten werden üblicherweise mit Fertigern aufgebracht, denen ein Baumaterial, beispielsweise Asphalt, Beton oder Schotter über einen Beschicker zugeführt wird oder die einen Vorratsbehälter für das Baumaterial aufweisen, der bedarfsweise befüllt wird. Eine Längsfördereinrichtung transportiert das Baumaterial aus dem Vorratsbehälter oder von einer Beschickungsöffnung zu einer Querverteilungseinrichtung, die das Baumaterial gleichmäßig über eine Einbaubreite verteilt. Eine über Nivellierholme in der Höhe geführte Verdichtungsbohle glättet und verdichtet das Baumaterial anschließend auf einem Untergrund.Tarpaulin coatings are usually applied with finishers to which a building material, for example asphalt, concrete or gravel is supplied via a feeder or which have a reservoir for the building material, which is filled as needed. A longitudinal conveyor transports the building material from the storage container or from a feed opening to a transverse distribution device, which distributes the building material evenly over a paving width. A compacting beam guided above leveling bars smoothes and then compacts the building material on a substrate.
Derzeit dominiert die Asphaltbauweise, da Asphalt eine Reihe von Vorteilen aufweist. Um die Asphaltbauweise besser den Belastungen des Schwerverkehrs anzupassen, wird eine Erhöhung des Verdichtungsgrades und die Reduzierung der Stärke der Deckschichten angestrebt. Zur Erzielung einer wirksamen Abdichtung der Deckschicht sowie zur Minimierung der Alterung der Bindemittel und zur Vermeidung von Spurrillen, Deckenschäden, Rissen und Abplatzungen wird in zunehmendem Maße Kompaktasphalt eingesetzt, bei dem zwei Schichten gleichzeitig heiß-auf-heiß verlegt werden. Der Einbau erfolgt meist entweder mit zwei Fertigern, wobei der zweite Fertiger direkt hinter dem ersten Fertiger einbaut, mit dem Nachteil, dass der zweite Fertiger auf der ersten eingebauten Belagsschicht fahren muss. Alternativ werden Spezialfertiger verwendet, die alle notwendigen Arbeitsfunktionen von zwei Fertigern in einer Maschine vereinigen.At present, asphalt construction dominates because asphalt has a number of advantages. In order to better adapt the asphalt construction to the loads of heavy traffic, the aim is to increase the degree of compaction and to reduce the thickness of the surface layers. In order to achieve an effective sealing of the cover layer and to minimize the aging of the binder and to avoid ruts, ceiling damage, cracks and flaking compact asphalt is used increasingly in which two layers are laid simultaneously hot-on-hot. The installation is usually carried out either with two pavers, with the second paver installed directly behind the first paver, with the disadvantage that the second paver has to drive on the first installed paver layer. Alternatively, special pavers are used that combine all the necessary work functions of two pavers in one machine.

Weiter ist ein Gleitschalungsfertiger mit einem von einzeln angetriebenen Raupenfahrwerken getragenen Vierkantrahmen bekannt, in dem zwei Einbaubohlen hintereinander schwimmend vom Tragrahmen geschleppt werden. Diese Straßenbaumaschine ist in der Lage, zwei getrennte Betoneinbauschichten einzubauen. Nachteilig ist, dass die Einbaubreite durch die Gleitschalung begrenzt ist und die Einbaubreite innerhalb der Raupen-Fahrwerke angeordnet sind.Next, a slipform paver with a supported by individually driven crawler chassis square frame is known in which two screeds are dragged successively swimming from the support frame. This road construction machine is able to install two separate concrete inlay layers. The disadvantage is that the pave width is limited by the slip formwork and the paving width are arranged within the crawler tracks.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine erfindungsgemäße Arbeitsmaschineneinheit, insbesondere zum Einbau und zum Verdichten von Straßenbelagsschichten, umfasst zumindest Teile eines ersten und eines zweiten Fertigers, insbesondere zweier handelsüblicher Fertiger. Beide Fertiger umfassen jeweils zumindest eine Karosserie, eine Beschickungsöffnung oder einen Vorratsbehälter für einzubauendes Baumaterial, eine Längsfördereinrichtung zur Förderung des Baumaterials zu einer Querverteilungseinrichtung für dessen Verteilung über eine Einbaubreite und mit der Karosserie über zwei Nivellierholme verbunden eine Verdichtungsbohle zum Verdichten und/oder Glätten des Baumaterials auf einem Untergrund. Der zweite Fertiger ist auf dem ersten Fertiger stehend angeordnet und mit diesem direkt oder indirekt gekoppelt. Zumindest der erste Fertiger weist ein Fahrwerk auf. Die Nivellierholme des zweiten Fertigers sind so modifiziert, dass die Verdichtungsbohle des zweiten Fertigers in Fahrtrichtung der Arbeitsmaschineneinheit hinter der Verdichtungsbohle des ersten Fertigers in weitgehend gleicher Höhe wie die Verdichtungsbohle des ersten Fertigers liegt. Insbesondere sind die Nivellierholme zu diesem Zweck in ihrer Länge und nach unten verlängert. Die Querverteilungseinrichtungen sind ihrer jeweiligen Verdichtungsbohle in Fahrtrichtung vorgelagert. Die Karosserie der ersten Arbeitsmaschine ist hierzu insbesondere so ausgelegt, dass sie die Last des zweiten Fertigers tragen kann. Eine solche Arbeitsmaschineneinheit ermöglicht zum einen den Einbau eines zweischichtigen Asphaltbelags oder den Einbau von Deckschichten aus anderen Materialien. Zwei vorhandene Fertiger müssen lediglich auf die beschriebene Weise kombiniert werden. Der Transport zweier einzelner Fertiger ist deutlich weniger aufwändig als der Transport eines erheblich größeren kombinierten Fertigers. Bei Bedarf lässt sich die Arbeitsmaschinenanordnung wieder zerlegen, so dass die Fertiger auch für andere Aufgaben, wie den Einbau einschichtiger Beläge nutzbar sind. Durch die erfindungsgemäße Anordnung von zwei Verdichtungsbohlen besteht ferner die Möglichkeit, getrennte Profile für die beiden Schichten zu erzeugen, z.B. können Regenrinnen eingebracht werden.A working machine unit according to the invention, in particular for installation and compacting of paving layers, comprises at least parts of a first and a second paver, in particular two commercially available pavers. Both pavers each comprise at least one body, a feed opening or a reservoir for building material to be installed, a longitudinal conveyor for conveying the building material to a transverse distribution device for its distribution over a pave width and connected to the body via two leveling beams a compaction plank for compacting and / or smoothing of building material on a surface. The second paver is arranged standing on the first paver and coupled with this directly or indirectly. At least the first paver has a landing gear. The leveling beams of the second paver are modified such that the compaction pile of the second paver lies in the direction of travel of the working machine unit behind the compaction pile of the first paver in substantially the same height as the compaction pile of the first paver. In particular, the leveling bars are lengthened and downwardly for this purpose. The transverse distribution devices are preceded by their respective compaction booms in the direction of travel. The body of the first working machine is for this purpose in particular designed so that it can carry the load of the second paver. Such a work machine unit enables on the one hand the installation of a two-layer asphalt surface or the installation of outer layers of other materials. Two existing pavers only have to be combined in the manner described. The transport of two individual pavers is significantly less complicated than the transport of a much larger combined paver. If necessary, the working machine arrangement can be disassembled again so that the pavers can also be used for other tasks, such as the installation of single-layer coverings. The inventive arrangement of two compaction planks also makes it possible to create separate profiles for the two layers, eg rain gutters can be introduced.

Insbesondere wird sie zu diesem Zweck mittels eines Hebezeugs, beispielsweise eines Autokrans, auf der Karosserie des ersten Fertigers abgesetzt. Bevorzugt weist hierzu der der zweite Fertiger ein demontierbares Fahrwerk auf. Eine solche Anordnung ist besonders kompakt.In a first embodiment, the body of the second paver can be mounted directly on the body of the first paver. In particular, it is sold for this purpose by means of a hoist, such as a truck crane, on the body of the first paver. For this purpose, the second paver preferably has a demountable chassis. Such an arrangement is particularly compact.
Insbesondere wird bei dieser Ausführungsform vor der Befestigung des zweiten Fertigers auf der Karosserie des ersten Fertigers ein Fahrwerk des zweiten Fertigers demontiert.In particular, in this embodiment, prior to attachment of the second paver to the body of the first paver, a landing gear of the second paver is disassembled.
In einer weiteren, bevorzugten Ausführungsform wird der mit einem Fahrwerk versehene zweite Fertiger über eine geneigte Zufahrtsrampe auf eine mit der Karosserie des ersten Fertigers verbindbare Standrampe gefahren, wobei die Zufahrtsrampe mit der Standrampe verbindbar ist. Vorteilhaft ist hier, dass weder eine Demontage des Fahrwerks des zweiten Fertigers noch ein Hebezeug zum Aufsetzen des zweiten Fertigers auf den ersten Fertiger notwendig ist. Die Zufahrtsrampe wird vorzugsweise nach der Befestigung des zweiten Fertigers entfernt.In a further, preferred embodiment, the second paver provided with a chassis is driven via an inclined access ramp onto a stand ramp which can be connected to the body of the first paver, wherein the access ramp can be connected to the stationary ramp. It is advantageous here that neither a disassembly of the chassis of the second paver nor a hoist for placing the second paver on the first paver is necessary. The access ramp is preferably removed after attachment of the second paver.
Vorzugsweise werden sowohl bei Montage des zweiten Fertigers ohne Fahrwerk als auch beim Auffahren auf die Standrampe die Nivellierholme und/oder die Verdichtungsbohle und/oder die Querverteilereinrichutng des zweiten Fertigers vor der Befestigung auf der Karosserie des ersten Fertigers demontiert.Preferably, both during assembly of the second paver without landing gear and when driving on the pedestal the leveling beams and / or the compaction board and / or the Quererverteilereinrichutng the second paver are dismantled prior to attachment to the body of the first paver.
Die Zufahrtsrampe zum Auffahren des zweiten Fertigers kann dabei in Fahrtrichtung oder entgegen der Fahrtrichtung der Arbeitsmaschineneinheit mit der Standrampe verbunden werden, d.h. vor oder hinter der Arbeitsmaschineneinheit.The access ramp for ascending the second paver can be connected in the direction of travel or against the direction of travel of the working machine unit with the standard ramp, i. in front of or behind the working machine unit.
Vorzugsweise ist zur Verbindung des zweiten Fertigers mit dem ersten Fertiger oder zur Verbindung der Standrampe mit mindestens einem der Fertiger mindestens ein mechanischer Schnellverschluss, beispielsweise in der Art eines Schnappverschlusses, wie er von mechanischen Schnellwechslern oder Dreipunktgestängen selbstfahrender Arbeitsmaschinen bekannt ist, vorgesehen. Auf diese Weise kann zeitaufwändiges Schrauben entfallen.Preferably, to connect the second paver to the first paver or to connect the pedestal ramp to at least one paver, there is provided at least one mechanical quick fastener, such as a snap fastener, as known from mechanical quick couplers or three-point linkage of self-propelled work machines. In this way, time-consuming screws can be omitted.
Die Nivellierholme des zweiten Fertigers sind vorzugsweise austauschbar. Auf diese Weise können sowohl Standard-Nivellierholme zum Solobetrieb des zweiten Fertigers als auch modifizierte Nivellierholme zum Betrieb in der Arbeitsmaschineneinheit montiert werden.The leveling beams of the second paver are preferably interchangeable. In this way, both standard leveling beams for solo operation of the second paver as well as modified leveling beams for operation in the work machine unit can be mounted.
Mindestens eine der Querverteilungseinrichtungen ist vorzugsweise als Verteilerschnecke ausgebildet. Verteilerschnecken eignen sich besonders für eine gleichmäßige Verteilung des Baumaterials über die Einbaubreite.At least one of the transverse distribution devices is preferably designed as a distributor screw. Distribution screws are particularly suitable for a uniform distribution of the building material over the paving width.
In einer bevorzugten Ausführungsform sind Adapter zur Befestigung der Querverteilungseinrichtung des zweiten Fertigers vorgesehen, um diese auf besonders einfache Weise in die für den Einbau angestrebte Position in Fahrtrichtung unmittelbar vor der Verdichtungsbohle des zweiten Fertigers anzuordnen.In a preferred embodiment, adapters for fixing the transverse distribution device of the second finisher are provided to arrange them in a particularly simple manner in the desired position for installation in the direction of travel immediately before the compaction plank of the second paver.
Bevorzugt ist mindestens eine der Längsfördereinrichtungen als ein Kratzkettenförderer ausgebildet. Kratzkettenförderer sind wegen ihrer Robustheit besonders für den Transport typischer Baumaterialien geeignet.Preferably, at least one of the longitudinal conveying devices is designed as a scraper chain conveyor. Because of their robustness, scraper chain conveyors are particularly suitable for the transport of typical building materials.
In einer bevorzugten Ausführungsform weist die Längsfördereinrichtung des zweiten Fertigers ein Verlängerungselement zur Zuführung des Baumaterials zur Querverteilungseinrichtung des zweiten Fertigers auf, da sich auf Grund der Anordnung des zweiten Fertigers auf dem ersten und dem Längsversatz der Verdichtungsbohlen eine größere Distanz zwischen der Längsfördereinrichtung und der Querverteilungseinrichtung des zweiten Fertigers ergibt. Das Verlängerungselement kann beispielsweise die Form einer geneigten Ebene aufweisen.In a preferred embodiment, the longitudinal conveyor of the second paver has an extension element for feeding the building material to the transverse distributor of the second paver, because a greater distance between the longitudinal conveyor and the transverse distributor of the compactor due to the location of the second paver on the first and longitudinal displacements of the compaction pavers second paver results. The extension element may for example have the shape of an inclined plane.
Vorzugsweise ist mindestens eine der Verdichtungsbohlen als eine Standardbohle oder als eine Ausziehbohle ausgebildet. Ausziehbohlen erlauben eine variable Einbaubreite. Die Verdichtungsbohlen können mit je einem Hochverdichtungsaggregat versehen sein. Die Verdichtungsbohle des ersten Fertigers dient beispielsweise als Einbau- und Vorverdichtungsbohle und ermöglicht eine extrem hohe Vorverdichtung, weshalb eine gegenüber den nach bekannten Verfahren verlegten Belägen wesentlich höhere Ebenflächigkeit des zweischichtigen Belages erreicht wird. Die so erzielte hohe Ebenflächigkeit ermöglicht es, in Verbindung mit der hohen Vorverdichtung, die gegebenenfalls noch erforderliche Nachverdichtung auf ein Mindestmaß zu reduzieren. Es können serienmäßige, für die üblichen Fertiger verwendbare Querverteilungseinrichtungen und Verdichtungsbohlen verwendet werden. Eine beliebige Kombination verschiedener Typen von Verdichtungsbohlen am ersten und am zweiten Fertiger ist möglich.Preferably, at least one of the compaction planks is formed as a standard plank or as a pull-out plank. Extending screeds allow a variable paving width. The compaction piles can each be provided with a high-compression unit. The compaction plank of the first paver serves, for example, as a built-in and preconsolidation screed and permits an extremely high degree of precompression, which is why, compared with the linings laid by known methods, substantially greater flatness of the two-layer pavement is achieved. The high level of flatness achieved in this way makes it possible, in conjunction with the high pre-compression, to minimize any re-compaction that may be required. It can be used as standard, usable for the usual pavers transverse distribution devices and compaction planks become. Any combination of different types of compaction planks on the first and second pavers is possible.
Eine Nivellierung der Verdichtungsbohlen ist entweder gemeinsam für beide Verdichtungsbohlen oder separat steuerbar und/oder regelbar ausgeführt. Hierzu werden Aktoren der Fertiger, insbesondere Gasdruckzylinder zur Betätigung der Nivellierholme, mit einer gemeinsamen Steuereinheit verbunden. Ziel ist dabei, dass beide Verdichterbohlen voneinander unabhängig frei schwimmend arbeiten können, d.h. das die Höhenposition einer der Verdichterbohlen die der anderen Verdichterbohle nicht zwingend bestimmt.A leveling of the compaction piles is carried out either jointly for both compaction piles or separately controllable and / or adjustable. For this purpose, actuators of the paver, in particular gas pressure cylinder for actuating the leveling beams, are connected to a common control unit. The aim is that both compacting piles can operate independently of each other freely floating, i. that does not necessarily determine the height position of one of the compacting piles that of the other compacting pebble.
Bevorzugt werden vom ersten Fertiger vor der Befestigung des zweiten Fertigers ein Fahrerhaus und/oder ein Fahrerpult und/oder ein Fahrersitz und/oder ein Schalldämpfer demontiert, um die Arbeitsmaschineneinheit möglichst kompakt zu halten und die Montage zu erleichtern. Der Schalldämpfer kann durch einen modifizierten Schalldämpfer ersetzt werden, der die Anordnung des zweiten Fertigers auf dem ersten Fertiger gestattet. Fahrersitz und Fahrerpult können eine als Arbeitsplattform bezeichnete Einheit bilden, die leicht verschieblich und entfernbar ist.Preferably, a cab and / or a driver's desk and / or a driver's seat and / or a silencer are dismantled by the first paver before attaching the second paver to keep the work machine unit as compact as possible and to facilitate assembly. The silencer can be replaced by a modified silencer that allows the second paver to be placed on the first paver. Driver's seat and driver's desk can form a unit called a work platform, which is easy to move and remove.

Dabei werden zumindest Teile eines ersten Fertigers und eines zweiter Fertigers miteinander gekoppelt, wobei der erste Fertiger ein Fahrwerk, eine Karosserie, eine Beschickungsöffnung oder einen Vorratsbehälter für ein einzubauendes erstes Baumaterial, eine Längsfördereinrichtung zur Förderung des ersten Baumaterials zu einer Querverteilungseinrichtung für dessen Verteilung über eine Einbaubreite und mit der Karosserie über zwei Nivellierholme verbunden eine Verdichtungsbohle zum Verdichten und/oder Glätten des ersten Baumaterials auf einem Untergrund umfasst. Der eine Karosserie, eine Beschickungsöffnung oder einen Vorratsbehälter für ein einzubauendes zweites Baumaterial und eine Längsfördereinrichtung zur Förderung des zweiten Baumaterials umfassende zweite Fertiger wird dabei direkt oder indirekt auf der Karosserie des ersten Fertigers befestigt. Dabei wird oder ist der zweite Fertiger zumindest mit zwei modifizierten Nivellierholmen, einer Verdichtungsbohle und einer Querverteilungseinrichtung so versehen, dass die Verdichtungsbohle des zweiten Fertigers in Fahrtrichtung der Arbeitsmaschineneinheit hinter der Verdichtungsbohle des ersten Fertigers in weitgehend gleicher Höhe wie die Verdichtungsbohle des ersten Fertigers liegt und dass die Querverteilungseinrichtungen ihrer jeweiligen Verdichtungsbohle in Fahrtrichtung vorgelagert sind. Das erfindungsgemäße Verfahren ermöglicht auf einfache Weise die Herrichtung einer Arbeitsmaschineneinheit, die zum einen den Einbau eines zweischichtigen Asphaltbelags oder den Einbau von Deckschichten aus anderen Materialien ermöglicht. Zwei vorhandene Fertiger können auf die beschriebene Weise besonders einfach kombiniert werden. Der Transport zweier einzelner Fertiger ist deutlich weniger aufwändig als der Transport eines erheblich größeren kombinierten Fertigers. Bei Bedarf lässt sich die Arbeitsmaschinenanordnung auf einfache Weise wieder zerlegen, so dass die Fertiger auch für andere Aufgaben, wie den Einbau einschichtiger Beläge nutzbar sind. Durch die erfindungsgemäß hergerichtete Anordnung von zwei Verdichtungsbohlen besteht die Möglichkeit, getrennte Profile für die beiden Schichten zu erzeugen, z.B. können Regenrinnen eingebracht werden.The method according to the invention for mounting a work machine unit is used in particular for installing and compacting paving layers.
