Description

Die Erfindung betrifft einen Deckenfertiger nach dem Oberbegriff des Anspruchs 1 wie in US-A-4 801 218 offenbart.The invention relates to a paver according to the preamble of claim 1 as disclosed in US-A-4,801,218.

Deckenfertiger (DE-A-4101417), die Einbaubohlen zum schwimmenden Einbau aufweisen, werden üblicherweise für eine Schichtdicke bis etwa 30 cm, gemessen hinter der Einbaubohle des Deckenfertigers, ausgelegt. Nur in seltenen Fällen wird bei der Grundauslegung des Deckenfertigers eine größere Schichtdicke vorgesehen. Der Grund hierfür besteht darin, daß für eine größere Schichtdicke das Förderband des Deckenfertigers zumindest im hinteren Maschinenbereich und die Verteilerschnecke sowie der Förderschacht und die Bohlentransportzylinder nebst sämtlichen Aufbauten, die oberhalb der Einbaubohle liegen, höher angeordnet werden müssen. Da Deckenfertiger zur jeweiligen Baustelle mittels Tieflader transportiert werden, wobei gewöhnlich auch Brückenunterführungen zu passieren sind, ist die Transporthöhe, gewöhnlich bestimmt durch Wetterdach- oder Kabinenaufbauten, entsprechend limitiert, um die Transportierbarkeit zu gewährleisten.Ceiling paver (DE-A-4101417), the screed for floating Have installation, are usually for a layer thickness up to about 30 cm, measured behind the screed of the paver. Only in rare cases is the basic design of the paver a larger layer thickness is provided. The reason for this is there in that for a greater layer thickness the conveyor belt of the paver at least in the rear area of the machine and the auger as well as the conveyor shaft and the screed transport cylinders along with all of them Superstructures that are above the screed can be arranged higher have to. As paver to the respective construction site using a low loader are transported, usually also bridge underpasses are the transport height, usually determined by Weather roof or cabin superstructures, limited accordingly for portability to ensure.

Für Anwendungsfälle mit außergewöhnlichen Schichtdicken (z.B. bis 50 cm) werden daher in der Regel die vorgenannten Elemente nur für diesen Sonderfall insgesamt nach oben versetzt, um sie nach Erledigung der Baumaßnahme wieder rückgängig zu machen. Bereits diese Maßnahmen sind mit einem erheblichen Montageaufwand verbunden und führen zudem dazu, daß die Querstege des Untertrums des Förderbandes Material vom Verteilerschneckenraum wieder nach vorne unter den Fertiger fördern, da der Freiraum unterhalb des Untertrums des Förderers in seiner Höhe nicht entsprechend vergrößert ist. Dies führt zu entsprechenden Störungen, die sogar zu einem Einbaustillstand führen können.For applications with exceptional layer thicknesses (e.g. up to 50 cm), the above-mentioned elements are therefore usually only for this special case altogether shifted to them after settlement to undo the construction work. Already these measures are associated with a considerable assembly effort and also lead to that the crossbars of the lower run of the conveyor belt material from the screw chamber convey back under the paver because the There is no free space below the lower run of the conveyor is enlarged accordingly. This leads to corresponding disturbances can even lead to installation downtime.

Aufgabe der Erfindung ist es, einen Deckenfertiger nach dem Oberbegriff des Anspruchs 1 zu schaffen, der ohne großen Umrüstaufwand auf einen erhöhten Schichtdickeneinbau umstellbar ist, ohne daß die Gefahr besteht, daß Störungen durch wieder nach vorne gefördertes Material auftreten.The object of the invention is to provide a paver after Generic preamble of claim 1 to create the without major retooling is convertible to an increased layer thickness without the risk there is interference due to material being conveyed forward again occur.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This task is performed according to the characteristic part of the Claim 1 solved.

Hierbei sind die Raupenfahrwerke des Deckenfertigers in ihrem vorderen Bereich drehbar am Maschinenrahmen gelagert und im hinteren Bereich in bezug auf den Maschinenrahmen höhenverstellbar, so daß der hintere Bereich des Förderers angehoben wird. Die Verstellung kann äußerst schnell erfolgen und ebenso schnell rückgängig gemacht werden.The crawler tracks of the paver finisher are in theirs front area rotatably mounted on the machine frame and in the rear area height adjustable with respect to the machine frame so that the rear Area of the conveyor is raised. The adjustment can be extreme done quickly and undone just as quickly.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention are as follows Description and the dependent claims.

Die Erfindung wird nachstehend anhand eines in der beigefügten Abbildung schematisiert dargestellten Ausführungsbeispiels näher erläutert.

  • Fig. 1 zeigt einen Deckenfertiger in Seitenansicht beim Einbau einer Schicht geringer Dicke.
  • Fig. 2 zeigt einen Deckenfertiger in Seitenansicht beim Einbau einer Schicht großer Dicke.
    • The invention is explained in more detail below on the basis of an exemplary embodiment shown schematically in the attached figure.
  • Fig. 1 shows a paver in side view when installing a layer of small thickness.
  • Fig. 2 shows a paver in side view when installing a layer of great thickness.

    • Der dargestellte Deckenfertiger umfaßt ein Maschinenrahmen 1 mit seitlichen Raupenfahrwerken 2. Frontseitig ist ein Kübel 3 mit seitlich auseinanderklappbaren Seitenwandteilen 4 vorgesehen, die an entsprechenden, darunter befindlichen, feststehenden Seitenwandteilen 5 angelenkt sind, um auseinandergeklappt einen Einfülltrichter für einzubauendes Material zu bilden. Ein umlaufender, gewöhnlich mit Querstegen versehener Förderer (nicht dargestellt) bildet den Boden des Kübels 3 und fördert eingefülltes Material zur Rückseite des Maschinenrahmens 1 in den Bereich einer dort befindlichen Verteilerschnecke 6, die das Material über die Einbaubreite verteilt. Das so verteilte Material wird mittels einer Einbaubohle 7, die gegebenenfalls zum Verbreitern seitlich ausfahrbar und/oder anstückelbar ist, unter Verdichten und Glätten eingebaut. Die auf dem einzubauenden Material schwimmende Einbaubohle 7 ist über Zugarme 8 am Maschinenrahmen 1 angelenkt und über Stellzylinder 9 in bezug auf eine gewünschte Einbauhöhe des einzubauenden Materials höhenverstellbar. Die Einbaubohle 7 kann Stampf- und/oder Vibrationsaggregate 10, 11 umfassen. Die Einbaubohle 7 ist über einen Bohlentransportzylinder 12 in eine zum Transport des Deckenfertigers geeignete Stellung anhebbar. Über dem Förderschacht des Förderers sind Aufbauten mit einem Fahrerstand 13, einem Antriebsmotor und dergleichen angeordnet.The paver shown comprises a machine frame 1 with side crawler tracks 2. On the front is a bucket 3 with side unfoldable side wall parts 4 are provided, which on corresponding, underneath, fixed side wall parts 5 articulated are to unfold a hopper for what is to be installed To form material. A circumferential, usually with cross bars provided conveyor (not shown) forms the bottom of the bucket 3 and conveys filled material to the rear of the machine frame 1 in the area of a distributor screw 6 located there, which the material distributed over the pave width. The material so distributed will by means of a screed 7, which can be used laterally to widen is extendable and / or can be cut, under compression and smoothing built-in. The screed 7 floating on the material to be installed is articulated via draw arms 8 on the machine frame 1 and via actuating cylinders 9 in relation to a desired installation height of the material to be installed height-adjustable. The screed 7 can ramming and / or vibration units 10, 11 include. The screed 7 is via a screed transport cylinder 12 into one suitable for transporting the paver finisher Position can be raised. There are superstructures above the conveyor shaft of the conveyor with a driver's station 13, a drive motor and the like.

    Die Raupenfahrwerke 2 sind im Bereich ihres vorderen Drittels um eine Achse 14 drehbar am Maschinenrahmen 1 gelagert. In ihrem hinteren Bereich sind die Raupenfahrwerke 2 gegenüber einer vertikalen Gleitführung 15, die fest mit dem Maschinenrahmen 1 verbunden ist, vertikal verstellbar. Für die Ausgangsstellung, aus der der Maschinenrahmen 1 hinten gegenüber den Raupenfahrwerken 2 anhebbar ist, kann ein Anschlag vorgesehen sein.The crawler tracks 2 are in the area of their front third mounted on the machine frame 1 so as to be rotatable about an axis 14. In her rear Area are the crawler tracks 2 compared to a vertical sliding guide 15, which is firmly connected to the machine frame 1, vertically adjustable. For the starting position from which the machine frame 1 can be raised against the crawler tracks 2 at the rear, a stop be provided.

    Die vertikale Verstellung der Raupenfahrwerke 2 gegenüber dem Maschinenrahmen 1 kann beispielsweise mittels Schraubspindeln vorgenommen werden. Jedoch werden entsprechende hydraulische Stellzylinder 16, jeweils einer pro Raupenfahrwerk 2, bevorzugt, die beispielsweise über den bei einem Deckenfertiger ohnehin vorhandenen Hydraulikkreislauf mittels eines Vier-/Dreiwegeventils elektrohydraulisch gesteuert und in der jeweils gewünschten Position über ein entsperrbares Zwillingsrückschlagventil gehalten werden können.The vertical adjustment of the crawler tracks 2 compared to that Machine frame 1 can be made using screw spindles, for example become. However, corresponding hydraulic actuating cylinders 16, one for each crawler track 2, preferably, for example, over the hydraulic circuit already present in a paver using of a four / three-way valve controlled electro-hydraulically and in the desired position via an unlockable twin check valve can be held.

    Hierdurch läßt sich in äußerst kurzer Zeit der hintere Teil des Deckenfertigers einschließlich der Einbaubohle 7 in eine gegenüber dem Fahrbahngrund 17 erhöhte Position bringen. Dann befinden sich sämtliche Aggregate wie Einbaubohle 7, Förderer, Verteilerschnecke 6, Bohlentransportzylinder 12 und die Aufbauten oberhalb der Einbaubohle 7 in eine für eine große Schichtdicke der einzubauenden Decke vorteilhaften Lage. Durch die höhere Position des Bohlentransportzylinders 12 kann die Einbaubohle 7 somit entsprechend große Schichtdicken einbauen.As a result, the rear part can be set in an extremely short time the paver including the screed 7 in one opposite Bring the ground 17 up. Then they are all there Units such as screed 7, conveyor, auger 6, screed transport cylinder 12 and the superstructure above the screed 7 in an advantageous one for a large layer thickness of the ceiling to be installed Location. Due to the higher position of the screed transport cylinder 12, the Screed 7 should therefore be built in to suit the corresponding thick layers.

    Durch den Hub der Stellzylinder 16 wird allerdings die minimale Höhe einer einbaubaren Schichtdicke im Verhältnis zur maximalen limitiert. Wenn nach einer Schicht mit entsprechend großer Schichtdicke wiederum Normalbeläge wie ca. 4 cm dicke Verschleißbeläge oder ca. 8 cm dicke Binderschichten eingebaut werden sollen, sind die Raupenfahrwerke 2 und damit der Maschinenrahmen 1 über die Stellzylinder 16 wieder entsprechend abzusenken. Allerdings kann dies ebenfalls sehr schnell vorgenommen werden, so daß keine langwierigen Umrüstarbeiten entstehen.Due to the stroke of the actuating cylinder 16, however, the minimum The height of an installable layer thickness in relation to the maximum is limited. If again after a layer with a correspondingly large layer thickness Normal coverings such as approx. 4 cm thick wear coverings or approx. 8 cm the crawler tracks are to be installed in thick binder layers 2 and thus the machine frame 1 via the actuating cylinder 16 again accordingly lower. However, this can also be done very quickly be, so that no lengthy retrofitting work.
