To improve the control of the tool there is provided in the joint area of the tool handle to the arm, on the tool handle or on the arm, a video camera of which the objective is directed to the working area of the tool, as well as a video monitor connected to the video camera inside the driver cabin of the excavator and in the field of vision of the driver.

Description

Die Erfindung geht aus von einem Bagger mit einem um eine senkrechte Achse und eine waagerechte Achse schwenkbaren Ausleger und einem am freien Ende des Auslegers angelenkten Werkzeugstiel, an dessen freiem Ende ein Werkzeug, insbesondere ein Tieflöffel oder ein Greiflöffel angebracht ist, mit einer im Bereich der Anlenkung des Werkzeugstiels am Ausleger an der Innenseite des Werkzeugstiels angeordneten und in einem Gehäuse untergebrachten Video-Kamera, die mit ihrem Objektiv auf den Arbeitsbereich des Werkzeugs gerichtet ist, und mit einem in der Führerkabine im Blickfeld des Baggerführers angeordneten Video-Monitor, der mit der Video-Kamera verbunden ist.The invention is based on an excavator with a boom pivotable about a vertical axis and a horizontal axis and a tool handle articulated on the free end of the boom, at the free end of which a tool, in particular a backhoe bucket or a gripping bucket, is attached, with one in the region of the Articulation of the tool handle on the boom on the inside of the tool handle and housed in a housing, the video camera with its lens is aimed at the working area of the tool, and with a video monitor arranged in the driver's cab in the field of vision of the excavator operator, which works with the Video camera is connected.

Ein Bagger dieser Art ist bekannt aus der FR-A-2 076 504. Bei diesem Bagger ist die Video- Kamera ungeschützt am oberen Bereich des Werkzeugstiels angebracht. Bei einer anderen Ausführungsform des bekannten Baggers ist die Video-Kamera in einem Gehäuse untergebracht, das um eine zur Schwenkachse des Werkzeugstiels parallelen Achse schwenkbar seitlich am oberen Bereich des Werkzeugstiels angeordnet ist. Mit Hilfe dieser auf den Arbeitsbereich des Werkzeuges gerichteten Video-Kamera und dem in der Führerkabine angeordneten Monitor kann der Fahrer des Baggers an sich ohne fremde Hilfe das Baggerwerkzeug, insbesondere den Baggerlöffel, zielgenau bewegen.An excavator of this type is known from FR-A-2 076 504. In this excavator, the video camera is attached to the upper area of the tool handle without protection. In another embodiment of the known excavator, the video camera is accommodated in a housing, which is arranged laterally on the upper region of the tool stick so as to be pivotable about an axis parallel to the pivot axis of the tool stick. With the help of this video camera directed towards the working area of the tool and the monitor arranged in the driver's cab, the driver of the excavator can move the excavator tool, in particular the excavator bucket, precisely without any outside help.

Der bekannte Bagger ist jedoch zum Ausheben und Verbauen tiefer Gräben ungeeignet, weil einerseits die beim Arbeiten vom Baggerwerkzeug ausgehenden Stöße und Schläge die Video-Kamera beschädigen würden und andererseits die Video-Kamera wegen ihrer ungeschützten Anordnung schnell abgerissen würde, wenn der Werkzeugstiel zwischen den Spreizen einer Verbauvorrichtung in einem tiefen Graben arbeiten müßte. Beim Ausheben tiefer Gräben werden mit Hilfe des Baggers die Grabenverbauvorrichtungen in den Graben eingesetzt oder herausgezogen, und zwar mit Hilfe eines Hakens, der am Tieflöffel des Baggers angebracht ist. Mit Hilfe des Baggers können Verbaueinheiten in den Graben eingesetzt werden, die aus zwei über Spreizen auf Abstand gehaltenen parallelen Verbauplatten zusammengesetzt sind. Es können aber auch die Elemente von Verbauvorrichtungen bewegt und eingesetzt werden, die sich aus Stützen und darin geführten Verbauplatten zusammensetzen. Die Stützen werden über Spreizen auf Abstand gehalten. Mit Hilfe des Baggerlöffels werden auch die Verbaueinheiten bzw. die Verbauplatten oder die Verbaustützen in das Erdreich gedrückt oder geschlagen. Ferner wird auch bei tieferen Gräben oder bei Gräben in nicht standsicheren Böden der Verbau, dem Aushub folgend, nachgedrückt. Bei einem derartigen Grabenverbau muß der Baggerlöffel nicht nur zwischen den Verbauplatten, sondern auch zwischen den Spreizen zeilgenau bewegt werden.However, the known excavator is unsuitable for digging and installing deep trenches because, on the one hand, the shocks and impacts from working with the excavator tool would damage the video camera and, on the other hand, the video camera would be torn off quickly due to its unprotected arrangement if the tool handle between the spreaders a shoring device would have to work in a deep trench. When digging deep trenches, the trenchers are inserted or pulled out of the trench with the help of a digger using a hook attached to the backhoe bucket. With the help of the excavator, shoring units can be inserted into the trench, which are composed of two parallel shoring panels that are spaced apart by spreaders. However, it is also possible to move and use the elements of shoring devices, which are composed of supports and shoring panels guided therein. The supports are kept at a distance by spreading. With the help of the excavator bucket, the shoring units or shoring panels or shoring supports are pressed or hammered into the ground. Furthermore, in the case of deeper trenches or trenches in non-stable soils, the shoring, following the excavation, is pressed down. In such a trench shoring, the excavator bucket not only has to be moved line by line between the shoring plates, but also between the spreaders.

Bei diesen Arbeiten wurde die ungeschützt und nach unten oder seitlich vorstehend angebrachte Video-Kamera des bekannten Baggers schnell beschädigt.During this work, the unprotected and downward or laterally projecting video camera of the known excavator was quickly damaged.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Bagger mit im Bereich der Anlenkung des Werkzeugstiels am Ausleger angeordneter und auf den Arbeitsbereich des Werkzeugs gerichteter Video-Kamera die Video-Kamera so anzuordnen, daß diese auch bei rauhem Baustellenbetrieb nicht ausfällt oder beschädigt wird.The invention has for its object to arrange the video camera in an excavator with in the area of the articulation of the tool handle on the boom and directed towards the working area of the tool so that it does not fail or be damaged even in rough construction site operation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Video-Kamera mittels Feder- und Dämpfungselementen stoßgedämpft im Gehäuse gehalten und das Gehäuse in einer Ausnehmung an der Innenseite des Werkzeugstiels eingesetzt ist.This object is achieved in that the video camera is shock-absorbed in the housing by means of spring and damping elements and the housing is inserted in a recess on the inside of the tool handle.

Bei dieser Anordnung der Video-Kamera wird diese auch nicht durch schlagende oder stoßende Bewegungen des Werkzeugstiels beschädigt. Die zumindest mit dem Objektiv aus der Unterseite des Werkzeugstiels vorragende Video-Kamera ist zumindest teilweise zwischen den Seitenwänden des Werkzeugstiels und im Bereich des Objektivs zwischen Abweiswänden angeordnet. Die Video-Kamera ist also völlig geschützt im oberen Bereich des Werkzeugstiels angeordnet und hat den gesamten Arbeitsbereich des Werkzeugs im Blickfeld.With this arrangement of the video camera, it is not damaged by striking or pushing movements of the tool handle. The video camera protruding at least with the lens from the underside of the tool handle is arranged at least partially between the side walls of the tool handle and in the region of the lens between deflecting walls. The video camera is therefore completely protected in the upper area of the tool handle and has the entire working area of the tool in view.

Bei einer anderen Ausführungsform der Erfindung, bei der die Kamera in einem um eine zur Schwenkachse des Werkzeugstiels parallelen Achse verschwenkbaren Gehäuse angeordnet ist, ist die Video-Kamera mittels Feder- und Dämpfungselementen stoßgedämpft im Gehäuse gehalten und das Gehäuse ist am freien Ende des Auslegers zwischen den Seitenwänden des Auslegers um eine zur Schwenkachse des Werkzeugstiels parallelen Achse angeordnet. Weitere Merkmale der Erfindung ergeben sich aus den Patentansprüchen 2 bis 5 und 7.In another embodiment of the invention, in which the camera is arranged in a housing which can be pivoted about an axis parallel to the pivot axis of the tool handle, the video camera is held in the housing in a shock-absorbing manner by means of spring and damping elements, and the housing is between the free end of the arm arranged the side walls of the boom about an axis parallel to the pivot axis of the tool handle. Further features of the invention emerge from patent claims 2 to 5 and 7.

Fig. 1 zeigt einen Bagger 1, der vor Kopf eines auszuhebenden Grabens angeordnet ist. Der Bagger weist einen um eine senkrechte Achse 3 und eine waagerechte Achse 4 schwenkbaren Ausleger 2 auf, an dessen freiem Ende um eine Achse 7 ein Werkzeugstiel 5 angelenkt ist, an dessen freiem Ende ein Tieflöffel 9 um die Achse 8 verschwenkbar angeordnet ist. Mit Hilfe des Baggers 1 wird ein Graben ausgehoben, der während des Aushubes bereits mittels vertikaler Stützen 30 die Stützen auf Abstand haltende Spreizen 31 und in den Stützen 30 geführten Verbauwände 32 abgesichert wird. Diese Verbaueinrichtung wird während des Aushubes kontinuierlich abgesenkt. Um die Aktionen des Tieflöffels beobachten zu können, ist an der Innenseite 6 des Werkzeugstieles 5 im Bereich 21 der Anlenkung des Werkzeugstiels 5 am Ausleger 2 ein Objektiv 20 einer Videokamera 10 angeordnet, die mit einem Video-Monitor 12 verbunden ist, welche in der Führerkabine 11 im Blickfeld des Baggerführers angeordnet ist. Die Videokamera 10 ist zumindest teilweise zwischen den Seitenwänden des Werkzeugstieles 5 angeordnet.Fig. 1 shows an excavator 1, which is arranged in front of the head of a trench to be excavated. The excavator has a boom 2 pivotable about a vertical axis 3 and a horizontal axis 4, at its free end by one Axis 7 a tool handle 5 is articulated, at the free end of which a backhoe 9 is arranged to be pivotable about the axis 8. With the help of the excavator 1, a trench is dug, which is already secured during the excavation by means of vertical supports 30, the supports spacing 31 and shoring walls 32 guided in the supports 30. This shoring device is continuously lowered during the excavation. In order to be able to observe the actions of the bucket, a lens 20 of a video camera 10 is arranged on the inside 6 of the tool handle 5 in the region 21 of the articulation of the tool handle 5 on the boom 2, which is connected to a video monitor 12 which is in the driver's cabin 11 is arranged in the field of vision of the excavator operator. The video camera 10 is at least partially arranged between the side walls of the tool handle 5.

Wie Fig. 2 zeigt, ist die Videokamera 10 mittels Feder- und Dämpfungselementen 17 stoßgedämpft im einem Gehäuse 16 untergebracht, das in einer Ausnehmung an der Innenseite 6 des Werkzeugstieles 5 eingesetzt ist. Die Kamera 10 ist völlig geschützt in diesem Gehäuse 16 angeordnet und ist durch federnde und dämpfende Elemente 17 beispielsweise aus Schaumgummi so stoßgesichert untergebracht, daß die Kamera nicht durch Stöße und Schläge beschädigt werden kann, welche vom Werkzeug 9 hervorgerufen werden. Das Gehäuse 16 mit der Videokamera 10 ist leicht auswechselbar, beispielsweise mittels Schrauben, am Werkzeugstiel 5 befestigt.As shown in FIG. 2, the video camera 10 is accommodated in a shock-absorbing manner by means of spring and damping elements 17 in a housing 16 which is inserted in a recess on the inside 6 of the tool handle 5. The camera 10 is completely protected in this housing 16 and is so shock-protected by resilient and damping elements 17, for example made of foam rubber, that the camera cannot be damaged by shocks and impacts caused by the tool 9. The housing 16 with the video camera 10 is easily replaceable, for example by means of screws, attached to the tool handle 5.

Wie die Fig. 3 zeigt, kann der Bagger 1 auch mit einem Greiflöffel 9' ausgerüstet sein, um einen relativ tiefen Rohrkanal auszuheben. Dabei steht der Bagger seitwärts neben dem auszuhebenden Kanal, der durch vorgerammte Dielen 33 und Steifen 34 abgesichert ist.As shown in FIG. 3, the excavator 1 can also be equipped with a gripper 9 'in order to excavate a relatively deep pipe channel. The excavator stands sideways next to the channel to be excavated, which is secured by pre-rammed planks 33 and strips 34.

In Fig. 4 ist die Videokamera 10 mit einem Winkelobjektiv 22 ausgebildet. Bei dieser Ausführungsform kann die Ausnehmung an der Innenseite 6 des Werkzeugstieles 5 relativ klein sein, so daß der Kastenhohlträger nicht oder nur geringfügig durch die Ausnehmung geschwächt wird. Das aus dem Werkzeugstiel herausragende Objektiv 22 der Kamera 10 ist zwischen Abweiswänden 23 geschützt untergebracht.4, the video camera 10 is designed with an angle lens 22. In this embodiment, the recess on the inside 6 of the tool handle 5 can be relatively small, so that the hollow box girder is not or only slightly weakened by the recess. The lens 22 of the camera 10 protruding from the tool handle is accommodated between the protective walls 23 in a protected manner.

Auch bei dem Ausführungsbeispiel nach Fig. 4 ist die Videokamera 10 schwingungsgedämpft in einem Gehäuse 16 untergebracht, welches schnell auswechselbar im Werkzeugstiel 5 eingesetzt ist.In the exemplary embodiment according to FIG. 4, the video camera 10 is accommodated in a vibration-damped manner in a housing 16 which is inserted in the tool handle 5 in a quickly replaceable manner.

Bei dem Ausführungsbeispiel nach Fig. 5 ist die Videokamera 10 um eine zur Schwenkachse 7 parallele Achse 25 verschwenkbar am freien Ende des Auslegers 2 angeordnet. Wird der Werkzeugstiel 5 gegenüber dem Ausleger 2 verschwenkt, so verschwenkt sich die Videokamera in gleicher Weise mit, so daß das Objektiv 20 stets auf den Arbeitsbereich des Werkzeuges 9 gerichtet ist. Zur Erzielung der entsprechenden Schwenkbewegung ist das die Videokamera aufnehmende Gehäuse 16 mit dem Werkzeugstiel 5 gekuppelt über eine Schwinge 26.
