Description

Die Erfindung bezieht sich auf ein Baufahrzeug mit einem Arbeitsgerät gemäß dem Oberbegriff von Anspruch 1.The invention relates to a construction vehicle with a working device according to the preamble of claim 1.

Das Baufahrzeug kann ein Fahrwerk mit Raupen oder mit bereiften Rädern aufweisen. Falls es sich um ein Fahrzeug mit Raupen handelt, so ist es in der Regel notwendig, dieses auf einem Tieflader zu der jeweiligen Baustelle zur transportieren. Mit Rädern versehene Baufahrzeuge können auch selbst zu den Baustellen gefahren werden, obwohl das meist unzweckmäßig ist. So werden Baufahrzeuge mit Rädern in Abhängigkeit von den zu bewältigenden Entfernungen ebenfalls auf Tiefladern transportiert. Bei einem derartigen Transport spielt die Breite des Arbeitsgerätes eine große Rolle. So kommt es immer wieder vor, dass das Arbeitsgerät, beispielsweise ein Schild von die Fahrzeugbreite übersteigernder Länge, eine zu große Breite besitzt, so dass es vor dem Transport abmontiert und nachher wieder angebracht werden muss. Das ist mit einem hohen Aufwand verbunden.The construction vehicle may have a chassis with caterpillars or with tired wheels. If it is a vehicle with caterpillars, then it is usually necessary to transport this on a low loader to the respective construction site. Wheeled construction vehicles can also be driven to the construction sites themselves, although this is usually inconvenient. Thus, construction vehicles with wheels are also transported on low loaders depending on the distances to be covered. In such a transport, the width of the implement plays a major role. So it happens again and again that the implement, such as a sign of the vehicle width exceeding length, has too large a width, so that it must be removed before transport and subsequently re-attached. This is associated with a lot of effort.

Ein Baufahrzeug der oben genannten Art ist beispielsweise aus der WO 97141309 A1 , der US 3,670,825 , der US 2,386,025 , der EP 0 587 175 A1 oder der DE 43 05 648 A1 bekannt.A construction vehicle of the above type is for example from the WO 97141309 A1 , of the US 3,670,825 , of the US 2,386,025 , of the EP 0 587 175 A1 or the DE 43 05 648 A1 known.

Aus US 5,634,523 ist nicht nur das eingangs beschriebene Baufahrzeug mit einem Schild bekannt sondern auch bereits vorgesehen, den die Fahrzeugbreite übersteigenden Schild außermittig mit seitlichem Abstand zur Längsmittelebene des Fahrzeugs mit vertikaler Achse am Träger anzulenken, so dass der Schild um diese vertikale Achse in eine Transportstellung verschwenkt werden kann, in der sich der Schild innerhalb der Fahrzeugbreite befindet, ohne dass dazu ein sich übermäßig weit nach vorne erstreckender Träger bzw. eine in größerem Abstand vor dem Fahrzeug angeordnete vertikale Achse für den Schild vorgesehen sein muss. Der Abstand der vertikalen Achse zur Längsmittelebene des Fahrzeugs ist jedoch nicht veränderbar. Das bedeutet, dass während des Arbeitsbetriebs unsymmetrische Kraftverteilungen auftreten und aufzufangen sind, was verschleißfördernd wird.Out US 5,634,523 Not only is the construction vehicle described above with a sign known but also already provided to deflect the vehicle width exceeding sign off-center with lateral distance to the median longitudinal plane of the vehicle with a vertical axis on the carrier, so that the shield can be pivoted about this vertical axis in a transport position in that the sign is within the vehicle width without the need for an excessively far forwardly extending support or a greater distance in front of the vehicle arranged vertical axis must be provided for the sign. The distance of the vertical axis to the median longitudinal plane of the vehicle is but not changeable. This means that unbalanced force distributions occur during working operation and must be collected, which increases wear.

Dementsprechend liegt der Erfindung die Aufgabe zugrunde, das Baufahrzeug so auszubilden, dass eine Breitenanpassung für den Transport vorgenommen werden kann, ohne dass dafür Nachteile im Arbeitsbetrieb in Kauf genommen werden müssen.Accordingly, the invention has the object, the construction vehicle in such a way that a width adjustment for the transport can be made without disadvantages must be taken into account during operation.

Diese Aufgabe wird erfindungsgemäß gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved by the characterizing features of claim 1.

Aus US 4,828,044 ist zwar ein Baufahrzeug bekannt, bei dem der Schild mittig am Träger mit einer in der Längsmittelebene des Fahrzeugs angeordneten vertikalen Achse angelenkt und diese in Querrichtung auslenkbar ist. Hierbei wird die vertikale Achse aber nicht parallel verlagert, sondern nur zur Seite hin gekippt, wobei die Achse in einem unteren Punkt mittels eines Kugelgelenks in der Längsmittelebene gehalten wird und mit einem oberen Bereich seitlich ausgeschwenkt wird. Diese Maßnahme dient dazu, den normalerweise waagerecht ausgerichteten Schild in einer Querebene in eine Schräglage zu verstellen. Mit einer Breitenanpassung zu Transportzwecken hat das nichts zu tun.Out US 4,828,044 Although a construction vehicle is known in which the shield is centered on the carrier with a arranged in the longitudinal center plane of the vehicle vertical axis and this is deflected in the transverse direction. Here, the vertical axis is not displaced parallel, but tilted only to the side, the axis is held in a lower point by means of a ball joint in the longitudinal center plane and is swung laterally with an upper portion. This measure is used to adjust the normally horizontal shield in a transverse plane in an inclined position. With a width adjustment for transport purposes, this has nothing to do.

Auf Grund der erfindungsgemäßen Ausbildung ist es möglich, für Transportzwecke die Anlenkstelle des Arbeitsgeräts zu verändern. Sie lässt sich z. B. derart zur Seite verlagern, dass das Arbeitsgerät in höherem Maße als bisher am Baufahrzeug verschwenkbar ist. Damit die Lage der Schwenkachse für das Arbeitsgerät aus ihrer mittigen Arbeitsposition in die seitliche Transportposition bewegbar ist, ist ferner vorgesehen, dass das als Träger für das Arbeitsgerät dienende Bauteil fahrzeugseitig verschwenkbar gelagert ist. Hierdurch lässt sich ein Schwenkradius erzielen, der nahezu der Länge des Trägers selbst entspricht. Die Folge hiervon ist, dass sich z. B. ein Schild trotz unmittelbarer Befestigung am Baufahrzeug extrem schräg zur Fahrzeuglängsrichtung einstellen lässt und dadurch weniger Platz in Breitenrichtung benötigt.Due to the inventive design, it is possible to change the articulation point of the implement for transport purposes. It can be z. B. shift so sideways that the implement is pivotable to a greater extent than before on the construction vehicle. Thus, the position of the pivot axis for the implement from its central working position in the lateral transport position is movable, it is further provided that the serving as a carrier for the implement component is mounted on the vehicle side pivot. As a result, a pivot radius can be achieved, which corresponds almost to the length of the carrier itself. The consequence of this is that z. B. leaves a sign despite direct attachment to the construction vehicle extremely oblique to the vehicle longitudinal direction and thus requires less space in the width direction.

Weitere Merkmale der Erfindung gehen aus Unteransprüchen und der Beschreibung in Verbindung mit der Zeichnung hervor.Further features of the invention will become apparent from the dependent claims and the description in conjunction with the drawings.

Ein Baufahrzeug 1 weist gemäß Fig. 1 ein Arbeitsgerät 2 auf, bei dem es sich insbesondere um einen Planierschild bzw. Schild 3 handelt, der mit Hilfe einer Trage- und Verstelleinrichtung 4 am Fahrzeugrahmen 5 angeordnet und bewegbar, dad heißt schwenkbar sowie anhebbar und absenkbar ist.A construction vehicle 1 has according to Fig. 1 a working device 2, which is in particular a dozer blade or shield 3, which is arranged with the aid of a carrying and adjusting device 4 on the vehicle frame 5 and movable, dad is called pivotable and can be raised and lowered.

Das Baufahrzeug 1 umfaßt ferner ein Fahrwerk 6 mit zum Beispiel zwei Raupen 7 und ein Oberfahrzeug 8 mit einer Fahrerkabine 9 und einem Motor 10.The construction vehicle 1 further comprises a chassis 6 with, for example, two tracks 7 and an upper vehicle 8 with a driver's cab 9 and a motor 10.

Die Trage- und Verstelleinrichtung 4 weist als tragende Bauteile für den Schild einen Träger 11 und ein Tragestück 12 auf. Der Schild 3 ist an dem Träger 11 angelenkt und das Tragestück 12 ist an dem Fahrzeugrahmen 5 angelenkt. Ferner sind der Träger 11 und das Tragestück 12 schwenkbar miteinander verbunden. Die Anlenkung des Schildes 3 am Träger 11 erfolgt längs einer senkrecht zur Fahrzeuglängsachse 13 stehenden Achse 14 (Fig. 1). Der Träger 11 und das Tragestück 12 sind um eine parallel zur Achse 14 stehende Achse 15 schwenkbar miteinander verbunden und das Tragestück 12 ist am Fahrzeugrahmen 5 im Bereich von seitlichen Wangen 16 um eine horizontal liegende Achse 17 bewegbar gelagert. Jeweils eine Wange 16 ist seitlich außen an dem Tragestück 12 angeordnet und liegt jeweils innen neben den Raupen 7.The carrying and adjusting device 4 has as a supporting components for the shield a carrier 11 and a support piece 12. The shield 3 is hinged to the carrier 11 and the support piece 12 is hinged to the vehicle frame 5. Further, the carrier 11 and the support piece 12 are pivotally connected to each other. The articulation of the shield 3 on the carrier 11 along a perpendicular to the vehicle longitudinal axis 13 axis 14 (FIG. Fig. 1 ). The carrier 11 and the supporting piece 12 are pivotally connected to one another about an axis 15 parallel to the axis 14 and the supporting piece 12 is movably mounted on the vehicle frame 5 in the region of lateral cheeks 16 about a horizontal axis 17. In each case, a cheek 16 is arranged laterally on the outside of the supporting piece 12 and lies in each case inwardly adjacent to the beads 7.

Um die Achse 17 sind das Tragestück 12 und mit ihm der Träger 11 sowie der Schild 3 anhebbar und absenkbar. Dazu dienen aus Kolbenstange 18 und Zylinder 19 bestehende hydraulische Einrichtungen 20 auf beiden Seiten des Baufahrzeuges 1. Die hydraulischen Einrichtungen 20 greifen jeweils an den Wangen 16 an.About the axis 17 are the support piece 12 and with him the carrier 11 and the shield 3 can be raised and lowered. Serve this purpose of piston rod 18 and cylinder 19 existing hydraulic devices 20 on both sides of the construction vehicle 1. The hydraulic devices 20 each engage the cheeks 16.

Zwei weitere, ebenfalls aus Kolbenstange 21 und Zylinder 22 bestehende hydraulische Einrichtungen 23 sind beidseitig an den Wangen 16 angelenkt und dienen zum Verschwenken des Schildes 3 um die Achse 14. Diese Situation ist in Fig. 2 dargestellt und zeigt, daß der Schild 3 um die Achse 14 aus einer mittleren Position nach rechts und nach links verschwenkbar ist.Two further, also consisting of piston rod 21 and cylinder 22 hydraulic devices 23 are articulated on both sides of the cheeks 16 and serve to pivot the shield 3 about the axis 14. This situation is in Fig. 2 illustrated and shows that the shield 3 is pivotable about the axis 14 from a middle position to the right and to the left.

Der Träger 11 befindet sich hierbei in einer mittigen Lage zum Baufahrzeug 1 bzw. relativ zu dessen Fahrzeuglängsachse 13.The carrier 11 is in this case in a central position to the construction vehicle 1 or relative to the vehicle longitudinal axis thirteenth

Die Achse 15, um die der Träger 11 schwenkbar am Tragestück 12 gelagert ist, schneidet nicht die Fahrzeuglängsachse 13 (Fig. 2). Sie liegt außermittig.The axis 15, about which the carrier 11 is pivotally mounted on the support piece 12, does not intersect the vehicle longitudinal axis 13 (FIG. Fig. 2 ). It lies off-center.

Damit der Träger 11 im normalen Betrieb nicht um die Achse 15 verschwenkbar ist, ist ferner eine Sicherungs- bzw. Blockiereinrichtung 24 (Fig. 3) vorgesehen. Diese Sicherung- und Blockiereinrichtung 24 fixiert entweder den Träger 11 in der Arbeitsposition am Tragestück 12 oder gibt den Träger 11 zum Verschwenken um die Achse 15 frei. Dieser Fall ist in Fig. 5 dargestellt.So that the carrier 11 is not pivotable about the axis 15 during normal operation, a securing or blocking device 24 (FIG. Fig. 3 ) intended. This securing and blocking device 24 either fixes the carrier 11 in the working position on the support piece 12 or releases the carrier 11 for pivoting about the axis 15. This case is in Fig. 5 shown.

Sobald die Sicherungs- und Blockiereinrichtung 24 den Träger 11 freigibt, ist er um die Achse 15 aus der Position gemäß Fig. 4 in die Position gemäß Fig. 5 verschwenkbar. Die Achse 14 bewegt sich dabei aus ihrer mittigen Lage von der Fahrzeuglängsachse 13 bzw. aus der senkrecht stehenden Fahrzeugmitteebene zu einer Seite des Baufahrzeuges 1 hin. Gleichzeitig kann die Kolbenstange 21 der einen hydraulischen Einrichtung 23' (Fig. 4) eingezogen und die andere Kolben 21 der anderen Kolben-Zylindereinrichtung 23'' maximal weit ausgefahren werden (Fig. 5), so daß der Schild 3 in eine nach links gerichtete Extremposition gelangt. Er nimmt jetzt nur noch eine geringe Breite relativ zur Breite des Baufahrzeuges 1 ein.Once the securing and blocking device 24 releases the carrier 11, it is about the axis 15 from the position according to Fig. 4 in the position according to Fig. 5 pivotable. The axis 14 moves from its central position from the vehicle longitudinal axis 13 and from the perpendicular Fahrzeugmitteebene to one side of the construction vehicle 1 out. At the same time, the piston rod 21 of a hydraulic device 23 '( Fig. 4 retracted and the other piston 21 of the other piston-cylinder device 23 '' maximum extent extended ( Fig. 5 ), so that the shield 3 enters a leftward extreme position. He now only takes a small width relative to the width of the construction vehicle 1.

Die Sicherungs- und Blockiereinrichtung 24 besteht zweckmäßiger Weise aus mindestens einem zum Blockieren dienenden Bolzen 25 bzw. gemäß Ausführungsbeispiel aus zwei zum Blockieren dienenden Bolzen 25 (Fig. 3) und einer hydraulischen Einrichtung 26, die die Bolzen 25 entweder in trägerseitige Halteöffnungen 27 schiebt oder aus diesen herauszieht.The securing and blocking device 24 expediently consists of at least one bolt 25 serving for blocking or, according to the exemplary embodiment, of two blocking bolts 25 (FIG. Fig. 3 ) and a hydraulic device 26, which pushes the bolts 25 either in carrier-side holding openings 27 or pulls out of these.

Der Träger 11 umgreift im Bereich der Sicherungs- und Blockiereinrichtung 24 das Tragestück 12 U-förmig, wie dies in Fig. 3 dargestellt ist.The carrier 11 surrounds in the region of the securing and blocking device 24, the support piece 12 U-shaped, as shown in FIG Fig. 3 is shown.

Die Achse 14 umfaßt ferner gemäß Fig. 3 zwei im Abstand voneinander angeordnete Lagerbolzen 28 und 29. Ihre Befestigung am Träger 11 und ihre schildseitige Verbindung ist dem Fachmann bekannt und in Fig. 3 konkret dargestellt.The axle 14 further includes according to Fig. 3 two spaced apart bearing pins 28 and 29. Their attachment to the carrier 11 and its shield-side connection is known in the art and in Fig. 3 shown in concrete.

Seitlich außen sowie bezüglich der Höhe zwischen den beiden Lagerbolzen 28 und 29 befinden sich Anlenkstellen 30 für die freien Enden der Kolbenstangen 21 der beiden hydraulischen Einrichtungen 23 (Fig. 3 und 4). Schildseitig angeordnete Tragelaschen 31 sind gemäß Ausführungsbeispiel ferner vorgesehen, um sowohl die Lagerung an den Lagerbolzen 28 und 29 als auch im Bereich der Anlenkstellen 30 mit den hydraulischen Einrichtungen 23 herzustellen. Dabei kann der Träger 11 zwei schildseitige Tragelaschen 31 auch U-förmig umgreifen oder er liegt mit einem Vorsprung 32 zwischen zwei schildseitigen Tragelaschen 31.On the outside and with respect to the height between the two bearing pins 28 and 29 are articulation points 30 for the free ends of the piston rods 21 of the two hydraulic devices 23 (FIGS. Fig. 3 and 4 ). Shield side arranged support tabs 31 are further provided according to embodiment, to produce both the bearing on the bearing pin 28 and 29 and in the region of the articulation points 30 with the hydraulic devices 23. In this case, the carrier 11 can embrace two shield-side support tabs 31 also U-shaped or he lies with a projection 32 between two shield-side support tabs 31st

Um eine optimale Schrägstellung des Schildes 3 zur Fahrzeuglängsachse 13 zu erzielen, ist die schildseitige Anlenkstelle 33 für die beim Schrägstellen maximal ausfahrbare Kolbenstange 21 der hydraulischen Einrichtung 23 (Fig. 5) bewegbar oder zumindest teilweise lösbar. Konkret befindet sich die Anlenkstelle 33 für das freie Ende der einen Kolbenstange 21 an einem schwenkbaren Lenker 34, der in seiner Arbeitsposition an der Lasche 31 zum Beispiel mit einem Bolzen 35 blockierbar ist. Zum Schrägstellen des Schildes 3 wird der Lenker 34 entriegelt, so daß die Bewegungsfreiheit des Schildes 3 noch etwas größer wird als bei verriegeltem Lenker 34.In order to achieve an optimum inclination of the shield 3 to the vehicle longitudinal axis 13, the shield-side articulation point 33 for the maximum extendable in tilting piston rod 21 of the hydraulic device 23 (FIG. Fig. 5 ) movable or at least partially detachable. Specifically, the articulation point 33 is for the free end of a piston rod 21 on a pivotable arm 34 which is blockable in its working position on the tab 31, for example with a bolt 35. For tilting the shield 3, the handlebar 34 is unlocked, so that the freedom of movement of the shield 3 is still slightly larger than when the handlebar 34 is locked.

Die zum Verstellen des Schildes 3 dienenden hydraulischen Einrichtungen 23 verändern beim Schrägstellen des Schildes 3 auch ihre Lage relativ zum Baufahrzeug 1. Sie nehmen ebenfalls eine Schrägstellung ein, wie dies in Fig. 5 dargestellt ist.The serving for adjusting the shield 3 hydraulic devices 23 change when tilting the shield 3 and their location relative to the construction vehicle 1. They also assume an inclination, as in Fig. 5 is shown.

Das Tragestück 12 ist ein am Fahrzeugrahmen 5 vorstehendes Bauteil. Es kann bogenförmig sein (Fig. 5) und zusammen mit den Wangen 16 eine etwa U-förmige Grundform besitzen.The support piece 12 is a component projecting on the vehicle frame 5. It can be arcuate ( Fig. 5 ) and together with the cheeks 16 have an approximately U-shaped basic shape.

Ein üblicher Schild 3 weist etwa eine Größe entsprechend den Darstellungen in den Fig. 2, 4 und 5 auf. Grundsätzlich kann ein Schild 3' aber auch noch etwas größer sein und dazu mit seitlich anflanschbaren Verlängerungsteilen 40 und 41 versehen werden.
