Description
Die Erfindung betrifft einen an einem Unterwagen einer Baumaschine mit Kettenlaufwerk angeordneten Ausleger, der in Fahrtrichtung der Baumaschine seitlich absteht, wobei der Ausleger mit einem beweglichen Auslegerarm ausgestattet ist.The invention relates to an arranged on an undercarriage of a construction machine with chain drive boom which projects laterally in the direction of travel of the construction machine, wherein the boom is equipped with a movable boom.
Ein derartiger Ausleger ist aus der
Ferner sind Ausleger grundsätzlich an Planierraupen bekannt, bei denen das Planierschild um eine horizontale, innerhalb der Kettenführung und rechtwinklig zur Fahrzeuglängsachse angeordnete Achse, meist mit der Achse der hinteren Laufrolle übereinstimmend schwenkbar gehaltert ist.Furthermore, jibs are basically known on bulldozers, in which the dozer blade is mounted so as to be able to pivot about a horizontal axis arranged within the chain guide and at right angles to the vehicle longitudinal axis, usually coincidentally with the axis of the rear roller.
Die
Ferner sind Seitenausleger an Radfahrzeugen bekannt, die ein seitliches Arbeiten, beispielsweise im Randbereich von Verkehrswegen zum sogenannten Profilschneiden, erlauben.Furthermore, side arms are known on wheeled vehicles, which allow lateral work, for example in the edge region of traffic routes for so-called profile cutting.
Die Aufgabe der Erfindung besteht darin, einen Ausleger an einer Baumaschine für einen seitlichen Einsatz in Fahrtrichtung neben dieser Baumaschine mit gleichwohl erheblichen Lasten und somit Drehmomenten, wie beispielsweise für das seitliche Planieren, Grabenfräsen oder Asphaltfräsen anzugeben, der stabil und auch für die Anwendung für schwierige Baugründe geeignet ist und dabei ein schnelles Auswechseln des Auslegers und/oder der Anbaugeräte erlaubt.The object of the invention is to provide a boom on a construction machine for lateral use in the direction of travel next to this construction machine with nevertheless considerable loads and thus torques, such as for lateral planing, trenching or asphalt milling, the stable and also for the application of difficult Ground is suitable, while allowing a quick replacement of the boom and / or implements.
Gelöst wird diese Aufgabe mit einem Ausleger gemäß Anspruch 1.This object is achieved with a boom according to
Dadurch, dass der Ausleger mit einer Auslegerbefestigungsplatte zur abnehmbaren Befestigung am Unterwagen innerhalb des Kettenlaufwerks befestigt ist und der Ausleger mit einer Schnellkupplungsplatte am distalen Ende des Auslegerarms zum Halten von Anbaugeräten ausgestattet ist, kann durch die abnehmbare Befestigung dieser Seitenausleger bei Nichtgebrauch und insbesondere zum Transport der Baumaschine mit geringem Aufwand abgebaut und an einer neuen Baustelle wieder angesetzt werden. Ebenso sind die Anbaugeräte für den jeweiligen Einsatzzweck über die standardisierte Schnellkupplungsplatte jederzeit wechselbar.The fact that the boom is mounted with a boom mounting plate for detachable attachment to the undercarriage within the track drive and the boom is equipped with a quick coupling plate at the distal end of the boom for holding attachments, can be removed by the detachable attachment of this side boom when not in use and in particular for transport Construction machine with little effort dismantled and reassigned to a new construction site. Likewise, the attachments for the respective application via the standardized quick-release plate are interchangeable at any time.
Wenn der Auslegerarm einen teleskopierbaren Abschnitt nahe der Schnellkupplungsplatte aufweist, kann der Arbeitsabstand des an der Schnellkupplungsplatte angebrachten Anbaugerätes in Fahrtrichtung seitlich von der Baumaschine auf die gewünschte Arbeitsentfernung passend eingestellt werden.When the boom has a telescoping portion near the quick-release plate, the working distance of the attached to the quick-release plate attachment in the direction of travel can be adjusted laterally from the construction machine to the desired working distance suitable.
Dadurch, dass die Auslegerbefestigungsplatte zur abnehmbaren Befestigung am Unterwagen innerhalb des Kettenlaufwerks ein Wechselsystem aufweist, kann der gesamte Ausleger für den Transport besonders schnell und einfach abgebaut und wieder montiert werden. Ferner ist ein Wechsel von einem Auslegertyp zu einem anderen Auslegertyp erheblich erleichtert.The fact that the boom mounting plate has a removable system for removable attachment to the undercarriage within the crawler track, the entire boom for transport can be quickly and easily dismantled and reassembled. Furthermore, a change from one boom type to another boom type is greatly facilitated.
Wenn der Auslegerarm eine Parallelverstellung nahe der Auslegerbefestigungsplatte aufweist, kann eine feinfühlige Höheneinstellung des am Ausleger angebauten Anbaugeräts erreicht werden, ohne dass dieser in seiner räumlichen Orientierung gekippt, geschwenkt oder verdreht wird. Die Parallelverstellung wird bevorzugt über einen ersten Hydraulikzylinder angesprochen, der diagonal über die parallelogrammartig angelenkten Schenkel der Parallelverstellung verspannt ist.If the cantilever arm has a parallel adjustment near the cantilever mounting plate, a sensitive height adjustment can be made on the cantilever attached attachment can be achieved without this tilted in its spatial orientation, pivoted or twisted. The parallel adjustment is preferably addressed via a first hydraulic cylinder, which is clamped diagonally across the parallelogram-like hinged legs of the parallel adjustment.
Dadurch, dass an der Befestigungsplatte eine erste lotrechte Schwenkachse vorgesehen ist, kann bei Nichtgebrauch des Seitenauslegers beziehungsweise für den Transport der Baumaschine von einer Baustelle zur nächsten der Ausleger platzsparend seitlich angeschwenkt werden.Characterized in that a first vertical pivot axis is provided on the mounting plate, can be swiveled laterally when not in use of the side arm or for the transport of the construction machine from one construction site to the next, the boom.
Dadurch, dass an der Schnellkupplungsplatte eine dritte lotrechte Schwenkachse vorgesehen ist, kann das am Auslegerarm über die Schnellkupplungsplatte angebrachte Anbaugerät im jeweils gewünschten Arbeitswinkel ausgerichtet werden. Bevorzugt ist zum Schwenken um die dritte lotrechte Schwenkachse ein dritter Hydraulikzylinder vorgesehen, beispielsweise kann der dritte Hydraulikzylinder über einen kurzen Schwenkarm an der dritten lotrechten Schwenkachse so angelenkt werden, dass die Schnellkupplungsplatte und somit das daran befestigte Anbaugerät jeweils beidseitig vom Totpunkt dieses Schwenkmechanismusses um jeweils ca. 90° verschwenkt werden kann. Der Totpunkt kann dabei durch geschicktes Ansteuern des Hydraulikzylinders oder durch manuelle Hilfe am Anbaugerät durch eine Hilfsperson überbrückt werden.Characterized in that a third vertical pivot axis is provided on the quick coupling plate, the attachment arm mounted on the quick coupling plate can be aligned at the desired working angle. Preferably, for pivoting about the third vertical pivot axis, a third hydraulic cylinder is provided, for example, the third hydraulic cylinder can be articulated via a short pivot arm on the third vertical pivot axis so that the quick coupling plate and thus the attached attachment each on both sides of the dead center of this Schwenkmechanismusses to each approx . 90 ° can be pivoted. The dead center can be bridged by clever control of the hydraulic cylinder or by manual assistance on the attachment by an assistant.
Wenn als Anbaugeräte zum bedarfsweisen Befestigen an der Schnellkupplungsplatte ein Planierschild, eine Grabenfräse, eine Asphalteinbaubohle, ein Verdichterrad oder ein Erosionsschutzstreifenbearbeiter vorgesehen sind, können eine Vielzahl von seitlichen (Erd-)Bearbeitungen kontinuierlich fortschreitend ausgeführt werden, ohne, dass der Seitenraum befahren werden muss. So können beispielsweise Radwege neben einer Straße planiert, erstellt und verfestigt werden. Ebenso können Straßen-begleitende Drainagegräben effektiv mit einer Grabenfräse erstellt werden.When implements for attaching to the quick-release plate as needed are a dozer blade, a trench cutter, an asphalt screed, a compressor wheel, or an anti-erosion stripper, a plurality of side (earth) operations can be continuously performed without having to travel the side space. For example, bike paths can be leveled, created and consolidated next to a road. Similarly, road-accompanying drainage ditches can be effectively created with a trench cutter.
Dadurch, dass zwischen der Parallelverstellung und dem teleskopierbaren Abschnitt eine zweite lotrechte Schwenkachse mit Flanschplatte vorgesehen ist, kann der Ausleger bei Nichtgebrauch quasi seitlich und vorne (bzw. hinten) um die Baumaschine herum zum Transport angeklappt werden. Somit kann vermieden werden, dass der komplette Ausleger bei jeder Arbeitsunterbrechung, bei Transportfahrten oder bei Nichtgebrauch jeweils vollständig von der Baumaschine getrennt werden muss.Characterized in that between the parallel adjustment and the telescopic section, a second vertical pivot axis is provided with flange plate, the boom can be folded when not in use, virtually side and front (or rear) to the construction machine for transport. Thus, it can be avoided that the complete boom must be completely separated from the construction machine at each work interruption, during transport or when not in use.
Wenn an der Flanschplatte eine horizontale Schwenkachse vorgesehen ist, kann die Höhenlage und damit der Arbeitsbereich für das am Ende des Auslegerarms angesetzte Anbaugerät nochmals verändert werden. Im Gegensatz zur Parallelverstellung wird dabei jedoch keine allein parallele Höhenlageänderung erreicht, sondern der gesamte teleskopierbare Abschnitt des Auslegerarms mit der daran angesetzten Schnellkupplungsplatte und dem daran sitzenden Anbaugerät um die horizontale Achse verschwenkt.If a horizontal pivot axis is provided on the flange plate, the altitude and thus the working range for the attached to the end of the boom attachment can be changed again. In contrast to the parallel adjustment but no parallel altitude change is achieved, but the entire telescopic portion of the boom with the attached quick-release plate and the attached implement pivots about the horizontal axis.
Um bei besonders kraftaufnehmenden Tätigkeiten mit dem jeweils montierten Anbaugerät eine wirksame Übertragung und Ableitung der daraus resultierenden Drehmomente, insbesondere bei weit ausgefahrenem Ausleger zu erreichen, ist eine Verstärkungsstrebe zwischen dem Unterwagen und dem Auslegerarm vorgesehen.In order to achieve effective transmission and dissipation of the resulting torques, in particular at far extended boom for particularly force-absorbing activities with each mounted attachment, a reinforcing strut between the undercarriage and the boom is provided.

An der Befestigungsplattenbasis 12 ist ein Ausleger 2 mit einem im Wesentlichen gradlinigen Auslegerarm 20 über eine flanschartige Auslegerbefestigungsplatte 22 an der Baumaschine 1 befestigt. Zum Anklappen des Auslegers 2 an die Baumaschine 1 (parallel zur Fahrtrichtung X) ist eine erste lotrechte Schwenkachse 21 zur schwenkbaren Befestigung der Auslegerbefestigungsplatte 22 an der Befestigungsplattenbasis 12 vorgesehen.On the
An der Auslegerbefestigungsplatte 22 sitzt der Ausleger 2, beispielsweise horizontal ausgerichtet, jedoch im Winkel von 45° zur Fahrtrichtung X der Baumaschine 1 schräg seitlich nach vorn gerichtet. Von der Auslegerbefestigungsplatte 22 aus gesehen beginnt der Ausleger 2 mit einer Parallelverstellung 3, die in Form eines Parallelogramms angeordnete Schenkel 34 aufweist, wobei in einer Diagonalen ein erster Hydraulikzylinder 31 zur Höhenverstellung des abwärtigen Endes der Parallelverstellung 3 mit seiner Flanschplatte 33 ausgebildet ist.On the

Der Auslegerarm 20 besteht in Verlängerung des Flanschplattenanschlusses 43 aus einem teleskopierbaren Abschnitt 4 mit einem Außenrohr 41 und einem darin teleskopierbar geführten Innenrohr 42. Zum Auseinanderschieben des teleskopierbaren Abschnitts ist im Innenrohr 42 ein zweiter Hydraulikzylinder 46 vorgesehen. Ferner ist in
Am distalen Ende des teleskopierbaren Abschnitts 4 ist eine Schnellkupplungsplatte 5 über eine dritte lotrechte Schwenkachse 53 mittels an der Schnellkupplungsplatte 5 vorstehendem Betätigungshebel 51 über einen dritten Hydraulikzylinder 52 schwenkbar angeordnet. Bevorzugt kann dabei die Schnellkupplungsplatte 5 um einen durch den Anstellwinkel des Betätigungshebels 51 bewirkten Totpunkt um 90° nach links und 90° nach rechts verschwenkt werden. Die Schnellkupplungsplatte 5 bzw. das daran angesetzte, hier nicht dargestellte Anbaugerät wird zur Überwindung des Totpunktes manuell darüber bzw. durch geschickte Ansteuerung des dritten Hydraulikzylinders 52 und Bewegungsbeharrung über diesen Totpunkt fernbetätigt hinwegbewegt.At the distal end of the
Der Ausleger 2 wird über elektrische und hydraulische Versorgungsleitungen von der Baumaschine 1 versorgt. Bevorzugt kann dafür der Durchtrieb am Unterwagen 10 entsprechend geändert werden. Die Hydraulikleitungen sowie auch die elektrischen Leitungen können dann im Ausleger 2 bis zur Schnellkupplungsplatte 5 verlängert werden, sodass dort die erforderliche elektrische und/oder hydraulische Versorgung eines entsprechenden Anbaugerätes sichergestellt ist.The
Falls nicht ausreichend Steuerkanäle und/oder einzeln ansteuerbare Hydraulikschläuche vorliegen, kann die Steuerung auch per gesonderter Fernbedienung, bevorzugt per Funk erfolgen. Somit können eine Vielzahl von Zusatzfunktionen zur Steuerung der Hydraulikzylinder 31, 44, 46, 52 über diese gesonderte Fernsteuerung angesteuert werden. Darüberhinaus ist noch eine hydraulische und elektrische Versorgung des jeweilig an der Schnellkupplungsplatte 5 befestigten Anbaugerätes möglich und steuerbar.If there are not sufficient control channels and / or individually controllable hydraulic hoses, the control can also be done by remote control, preferably by radio. Thus, a variety of additional functions for controlling the

Eine kettengeführte Baumaschine 1 mit dem erfindungsgemäßen Seitenausleger 2 zeichnet sich dabei insbesondere durch die hohe Festigkeit und damit die wirksame Übertragung von am Anbaugerät wirkenden Kräften direkt auf das kettengeführte Fahrwerk der Baumaschine 1 aus, womit im Wesentlichen Drehmomente auf die Baumaschine 1 wirken, die ein Gieren (Bewegen um die senkrechte Fahrzeugachse) bewirken, dem durch das Kettenlaufwerk leicht gegengesteuert werden kann. Für den Transport des Fahrzeugs zu neuen Baustellen bzw. beim Verwenden der Baumaschine ohne Nutzung des Seitenauslegers, kann dieser durch die vorgesehenen ersten Schwenkachse 21 und zweiten Schwenkachse 32 so um den Unterwagen 10 herangeschwenkt werden, dass der angelegte Ausleger kaum beim sonstigen Gebrauch der Baumaschine stört.
