Description

Die Erfindung betrifft einen in einen Wippgreiferbagger umwandelbareii Löffelbagger mit auf dem Ausleger gelagerter Löffelvorschubmaschine. Das Neue besteht darin, daß die Löffelvorschubmaschine, als Einziehwerk für ein aus zwei Lenkern und einem von diesem getragenen Spitzenausleger bestehendes bekanntes Wippsystem dient und auf dem Grundlenker gelagert ist, von dem das Einziehseil zur Drehachse des Gegenlenkers geführt ist.The invention relates to a luffing grab excavator Umwandelbareii backhoe with a bucket feed machine mounted on the boom. The new thing is that the spoon feed machine, as a retraction mechanism for one of two links and one of this supported luffing jib existing known luffing system is used and on the Base link is mounted, from which the pull-in rope is guided to the axis of rotation of the counter link is.

Der Erfindungsgegenstand bietet den Vorteil, daß die Umwandlung des Löffelbaggers in einen Wippgredferbagger einfach und schnell durchgeführt werden kann, weil am Bagger ob erwägen keine Änderungen vorzunehmen sind, die Löffelvorschubmaschine gleich als Wippwerk dient, dieses Wippwerk durch Einziehen des vom Grundlenker zur Drehachse des Gegenlenkers geführten Seiles sofort betriebsfertig ist, ohne daß es schwieriger und zeitraubender Ausrichtarbeiten bedarf, daß die Drehachsen des Löffelbaggers für die Lagerung des Wippsytems benutzt werden können und daß man einen Wippgreiferbagger mit waagerechtem Lastwippweg durch das aus zwei Lenkern und einem Spitzenausleger bestehende Wippsystem erhält.The subject matter of the invention offers the advantage that the conversion of the backhoe can be carried out quickly and easily in a rocking excavator, because on Excavators are considering making no changes to the bucket feed machine serves as a luffing mechanism, this luffing mechanism by pulling in the from the basic link to Axis of rotation of the counter link guided rope is immediately ready for use without it difficult and time-consuming alignment work requires that the axes of rotation of the backhoe can be used for the storage of the luffing system and that you have a luffing grab excavator with a horizontal load luffing path thanks to the luffing system consisting of two links and a luffing jib receives.

Bekannt sind umwandelbare Löffelhagger, bei denen zur Umwandlung in ein anderes Gerät, z. B. in einen Tieflöffelbagger, ein Ausleger am Löffelstiel und ein an diesen Löffelstiel angelenktes Zugglied in die vorhandenen Drehachsen eingesetzt werden. Weiter sind Löffelbagger bekannt, bei denen zwecks Umwandlung in einen Wippgreiferbagger an Stelle des Löffels ein Greifer am Löffelausleger mit Hilfe eines beweglichen Stieles angeschlossen ist, wobei der Greifer nur etwa im selben beschränkten Ausmaß beweglich ist wie der Löffel, an dessen Stelle er tritt.Convertible backhoe excavators are known, in which to convert to another device, z. B. in a backhoe excavator, one boom on the dipperstick and one on this dipperstick articulated tension member can be used in the existing axes of rotation. Backhoe excavators are also known for which purpose Conversion into a luffing grab excavator instead of a bucket a grab on the bucket boom is connected with the help of a movable handle, the gripper only about is movable to the same limited extent as the spoon it is replacing.

Schließlich gibt es unter den zahlreichen Bauarten von Wippkranen auch solche mit einem Wippsystem aus zwei Lenkern und einem von 'diesem geführten Spitzenausleger. Es ist bei diesem Wippkran auch bekannt, das Einziehwerk für das Wippsystem auf dem Grundlenker zu lagern.After all, there are also many types of luffing cranes a luffing system made up of two control arms and a luffing jib guided by them. It is also known for this luffing crane to have the pull-in mechanism for the luffing system on the To store basic handlebars.

Abb. ι der Zeichnung zeigt den Löffelbagger, Abb. 2 diesen Bagger nach Umwandlung in einen Wippgrelferbagger.Fig. Ι of the drawing shows the backhoe, Fig. 2 this excavator after conversion into a Wippgrelfer excavator.

Das üblicherweise aus Unterwagen 2 und Oberwagen 3 bestehende Baggergestell ist mit Raupen 1 ausgerüstet. Der Ausleger 5 ist am Oberwagen 3 durch die Drehachse 4 angelenkt. Der Löffelstiel 6 wird durch die Vorschubmaschine 7 angetrieben. Das Löffelhuhwerk besteht aus der Trommel 8, dem Seil 9, der Umlenkrolle 10 am Ausleger 5 und der Löffelrolle 11 am Löffel 12. Dias Einziehen erfolgt von der Trommel ϊ 5 aus mittels des Seiles 16, das über Rollen 17 und 18 in den Drehachsen 19 und 20 geführt ist.The excavator frame usually consisting of undercarriage 2 and uppercarriage 3 is with Caterpillars 1 equipped. The boom 5 is articulated to the superstructure 3 by the axis of rotation 4. The dipper stick 6 is driven by the feed machine 7. The spoon mechanism consists of the drum 8, the rope 9, the pulley 10 on the boom 5 and the Spoon roller 11 on spoon 12. Inserting slides takes place from the drum ϊ 5 by means of the rope 16, which over rollers 17 and 18 in the Axes of rotation 19 and 20 is guided.

Soll der Bagger als Wippbaggergreifer arbeiten, so wird statt des Auslegers 5 ein Ausleger 25 verwendet, der ebenfalls um die Drehachse 4 drehbar ist. Die Achse 19 wirdIf the excavator is to work as a luffing excavator grab, instead of the boom 5, a Cantilever 25 is used, which is also rotatable about the axis of rotation 4. The axis 19 will

als Drehachse für einen Gegenlenker 26 benutzt, an -dessen Oberende der Spitzenausleger 27 angelenkt ist. Das Löffelhubseil 9 ist von der Trommel 8 kommend zu einer am Baggergestell angeordneten Rolle 28 und von dieser über die Rolle 29 am vorderen Ende des Spitzenaiuslegers 27 zum Greifer 30 geführt. used as the axis of rotation for a counter link 26, at the upper end of the fly jib 27 is hinged. The bucket hoist rope 9 is coming from the drum 8 to an am Excavator frame arranged roller 28 and of this guided via the roller 29 at the front end of the tip jib 27 to the gripper 30.

Das Wippen erfolgt mittels der Löffelvorschubmaschine 7, die zu diesem Zweck auf den Ausleger 25 gesetzt und mit einer Windentrommel 31 versehen ist. Das "Wipp seil 32 läuft von der Windentrommel 31 zu der Rolle 33 am oberen Ende des Grundlenkers 25, von dort zur Rolle ΐχ auf der Drehachse 19, wo es an irgendeinem dieser Mittel festgeschlagen ist. Das Hubwerk ist, wie aus der Zeichnung ersichtlich, vollkommen unabhängig von dem Wippwerk. Beim "Wippen und bei stillstehendem Hubwerk wird daher die Last nicht gehoben, sondern bewegt sich auf der annähernd waagerechten Linie 34. Natürlich kann auch, das Hubseil während des Wippens laufen, so daß der Greifer gehoben und gesenkt wird, also eine beliebige Bahn beschreibt. Die verschiedenen Stellungen des Ausleger wipp systems sind in der Abb. 2 gestrichelt oder strichpunktiert. angegeben.The luffing is done by means of the spoon feed machine 7, which for this purpose is placed on the boom 25 and with a winch drum 31 is provided. The "luffing rope 32 runs from the winch drum 31 to the role 33 at the upper end of the base link 25, from there to the roller ΐχ on the axis of rotation 19, where it is pegged to any of these agents. The hoist is like from the Drawing visible, completely independent of the luffing mechanism. With "bobbing and with When the hoist is at a standstill, the load is not lifted, but moves on the approximately horizontal line 34. Of course, the hoist rope can also be used while luffing run so that the gripper is raised and lowered, i.e. describes any path. The various positions of the boom luffing system are shown in dashed lines in Fig. 2 or dash-dotted. specified.

Das zusammengesetzte Wippsystem kann so gewählt werden, daß die Auslegerspitze sich während des Wippens auf einer Waagerechten bewegt. Da das Hubwerk gemäß der Erfindung von der Wippbewegung völlig entlastet ist, kann es mit ,anderen Antrieben, etwa mit dem Fahrwerk ο. dgl., verbunden werden, um den Antriebsmotor besser ausnutzen und gegebenenfalls auch eine bauliche Vereinfachung erzielen zu können.The composite luffing system can be chosen so that the boom tip is moved on a horizontal plane while rocking. Since the hoist according to the invention is completely relieved of the rocking movement, it can be used with other drives, for example with the chassis ο. Like., Are connected in order to better utilize the drive motor and, if necessary, also to be able to achieve a structural simplification.
