Abstract
Description
Die Erfindung bezieht sich auf einen Hängedrehkran mit einer auf Schienen verfahrbaren, nach unten ragenden Drehsäule zur horizontalen Verschwenkung eines zusätzlich um eine horizontale Schwenkachse schwenkbaren, teleskopierbaren Lastarmes und mit einer Kabine zur Aufnahme einer Bedienungsperson, wobei die Schwenkachse des Lastarmes am Ende des Teleskoparmes angeordnet ist.The invention relates to a overhead crane with one on rails movable, downward rotating column for the horizontal swiveling of a additionally telescopic, pivotable about a horizontal swivel axis Low load and with a cabin to accommodate an operator, the Pivot axis of the load arm is arranged at the end of the telescopic arm.
Derartige Einrichtungen sind insbesondere als Farmkran im Einsatz. Bedient wird ein solcher Kran von einer Kabine aus, welche üblicherweise mit der Drehsäule fest verbunden ist. Die Schwenkachse des üblicherweise teleskopierbaren Lastarmes verläuft nahe dem Ende der Drehsäule.Such devices are used in particular as a farm crane. A is operated such a crane from a cabin, which is usually firmly connected to the rotating column is. The pivot axis of the usually telescopic load arm runs near the end of the rotating column.
Bisher hat man keinen Vorteil darin gesehen, die Schwenkachse des Lastarmes, so wie dies bei Ladekränen bekannt ist, selbst wieder am Ende eines Hub- oder Teleskoparmes anzuordnen, weil man davon ausging, daß sich das Ende des Lastarmes im Sichtbereich des Bedienungspersonals befinden muß.So far, no advantage has been seen in the pivot axis of the load arm, so as is known with loading cranes, even at the end of a lifting or telescopic arm to arrange, because it was assumed that the end of the load arm in the Visibility of the operating personnel must be.
Tatsächlich hat man auch heute schon die Kräne in Situationen eingesetzt, wo der am Ende des Lastarmes angeordnete Arbeitsteil, beispielsweise ein mittels einer Kette absenkbarer Greifer, für das Bedienungspersonal nicht sichtbar ist. Um hier nicht blind arbeiten zu müssen, wurde auch schon vorgeschlagen, die Krankabine mittels eines Scherengitters an der Drehsäule zu lagern, um das Bedienungspersonal in die Nähe des Lastarmendes befördern zu können, um den Arbeitsvorgang zu beobachten.In fact, the cranes have already been used in situations where the Working part arranged at the end of the load arm, for example a chain lowerable gripper, which is not visible to the operating personnel. To not be blind here It has also been proposed to work in the crane cabin using a Store scissor lattices on the rotating column in order to keep the operating personnel nearby to be able to carry the end of the load arm to observe the work process.
Es sind an sich wesentlich einfachere Methoden denkbar, um eine außerhalb der geraden Sichtlinie des Bedienungspersonals liegende Arbeitsstelle zu überwachen, beispielsweise die Anbringung eines Spiegels am Ende der freien Sichtstrecke oder die Überwachung mittels einer Kamera. Damit wird es aber durchaus auch für Hängedrehkräne interessant, ein Arbeitsgerät nicht am Ende einer Kette, sondern am Ende eines teleskopierbaren Lastarmes anzuordnen, dessen säulenseitiges Ende verschiedenen Horizontalabstand von den Schienen aufweist, auf denen der Kran verfahrbar ist. Der Kern der Erfindung liegt somit darin, daß die Kabine mit einem ausfahrbaren Teil des Teleskoparmes verbunden ist. In essence, much simpler methods are conceivable to find one outside the to monitor the operator's straight line of sight, for example the attachment of a mirror at the end of the free line of sight or the Monitoring using a camera. However, this also makes it quite suitable for overhead slewing cranes interesting, an implement not at the end of a chain, but at the end of one To arrange telescopic load arm, the column-side end different Has horizontal distance from the rails on which the crane can be moved. The The essence of the invention is thus that the cabin with an extendable part of the Telescopic arm is connected.
Dabei muß die Bedienungsperson nicht die ganze Bewegung der Schwenkachse mitmachen, sondern die Kabine kann beispielsweise bei einem dreiteiligen Teleskoparm mit dem zweiten Teilarm verbunden sein.The operator does not have to do the entire movement of the pivot axis participate, but the cabin can, for example, with a three-part Telescopic arm to be connected to the second arm.
Eine weitere Erläuterung der Erfindung erfolgt anschließend anhand der Zeichnung. In
dieser ist
Die in Fig. 1 - 4 dargestellte Einrichtung ist ein Farmkran, welcher entlang von
Schienen 1 verfahrbar ist, welche im Inneren eines Gebäudes, beispielsweise einer
Scheune, angeordnet sein können. Verfahren wird der Kran mittels eines mit Rollen 7
versehenen Rahmens 8 in aus dem Stand der Technik bekannter Weise.The device shown in Figs. 1-4 is a farm crane, which along
Rails 1 is movable, which is inside a building, for example one
Barn, can be arranged. The crane is moved by means of a
Vom Rahmen 8 ragt eine plattenförmige Drehsäule 2 lotrecht nach unten, an welcher
ein Teleskoparm 5 starr befestigt ist, sodaß er die Drehung der Säule 2 mitmacht. Im
dargestellten Ausführungsbeispiel verläuft der Teleskoparm 5 horizontal, doch könnte
er auch schräg geneigt sein, sofern nur die Kabine 6 einigermaßen lotrecht ist. Diese
Kabine 6 ist nämlich in üblicher Weise zur Aufnahme der Bedienungsperson bestimmt
und enthält daher abgesehen von einer Sitzgelegenheit die notwendigen Betätigungshebel
für die verschiedenen Transport- und Arbeitsbewegungen des Krans.From the
Am Ende des Teleskoparmes 5 befindet sich eine horizontale Schwenkachse 3, um
welche in teleskopierbarer Lastarm 4 schwenkbar ist, an dessen Ende ein Greifer 9
schwenkbar angeordnet ist.At the end of the
Wesentlich für die Erfindung ist die starre Befestigung der Kabine 6 an einem der ausschiebbaren
Arme des Teleskoparmes 5, im dargestellten Fall am äußeren der beiden
ausschiebbaren Arme. Der zur Befestigung der Kabine 6 dienende Tragarm 10 ist insbesondere
der Draufsicht von Fig. 2 zu entnehmen. In dieser Darstellung ist übrigens
auch ersichtlich, wie die Drehbewegung des Krans über einen Ring 11 auf die
Säule 2 übertragen wird.What is essential for the invention is the rigid attachment of the
Fig. 3 und 4 zeigen die dargestellte Einrichtung im eingefahrenen Zustand, welcher funktionell dem Stand der Technik entspricht.3 and 4 show the device shown in the retracted state, which corresponds functionally to the state of the art.
Durch die Erfindung wird ein wesentlicher Nachteil bisheriger Farmkräne beseitigt.
Befand sich nämlich bisher der Arbeitsbereich in seitlichem Abstand von den Schienen
1, so war er zwar für das Arbeitsgerät, beispielsweise den Greifer 9, zugänglich, für
das Bedienungspersonal jedoch nicht einsehbar. Durch die erfindungsgemäß vorgesehene
Verfahrbarkeit der Kabine 6 kann jetzt jede mit dem Gerät durchführbare Arbeit
auch unmittelbar überwacht werden.A major disadvantage of previous farm cranes is eliminated by the invention.
So far, the working area was located at a lateral distance from the rails
1, it was indeed accessible for the implement, for example the
