Description

Bei Teleskopausleger!! tritt das Problem auf, eine gute und doch möglichst geringe Reibung aufweisende Führung bei gleichmäßiger hoher Biegefestigkeit des Auslegers zu erreichen.With telescopic boom !! if the problem occurs, a good guidance with the lowest possible friction and consistently high flexural strength of the To reach the boom.

Eine hohe Biegefestigkeit kann man dadurch erzielen, daß man dem Teleskopausleger Kastenform gibt. Um bai einem solchen Ausleger auch eine gute Führung zu erzielen, kann man für den inneren Träger ein Profil wählen, das an seinen. Kanten hervorstehende, in der Trägerrichtung verlaufende Führangen aufweist. Eine solche Maßnahme ist für Teleskopmasten bei Derrick-Kranen vorgeschlagen worden. Trägerwände und Führungen bestehen, hier aus einem Stück, dies bedingt aber, wenn, der Träger aus Blech gebogen wird, sehr schwierige und daher teure Abkantarbeiten. Außerdem sind bei der l>ekannten Ausbildung die Führungen scharfkantig, was entsprechend ausgebildete Führungsflächen am feststehenden Träger, also scharfkantige Umbiegungen erfordern. Derartige Umbiegungen, verursachen häufig Risse im Material und sollen daher vermieden werden.A high flexural strength can be achieved by giving the telescopic boom a box shape gives. In order to achieve good guidance with such a boom, one can use for the inner Carrier choose a profile that fits its. Protruding edges, guides running in the direction of the beam having. Such a measure is proposed for telescopic masts in derrick cranes been. Support walls and guides consist, here of one piece, but if so, the support is bent from sheet metal, very difficult and therefore expensive bending work. In addition, the l> e known training, the guides are sharp-edged, what correspondingly trained guide surfaces on require fixed support, so sharp-edged bends. Such bends often cause Cracks in the material and should therefore be avoided.

Die Erfindung beseitigt diese Mängel. Sie geht aus von einem Träger mit rechteckigem Querschnitt und glatten Wänden und schlägt vor, an den äußeren Längskauten, dieses Trägers Rundeisen aufzuschweißen oder auf andere Weise so zu befestigen, daß die als Führung bestimmte Fläche der Rundeisen erhalten bleibt. Auf diese Weise ist mit geringstem Aufwand an Material und Arbeitszeit eine Führung für den verschiebbaren Träger zu erzielen, durch die auch scharfkantige Umbiegungen am feststehenden Träger vermieden werden. An Stelle durchgehender Rundeisen kann man auch einzelne Rundeisenstücke in Abstand voneinander vorsehen, wodurch an Material und Gewicht gespart wird.The invention overcomes these shortcomings. It is based on a carrier with a rectangular cross-section and smooth walls and suggests welding round bars on the outer longitudinal cheeks of this support or to be fixed in some other way so that the surface of the round bars intended as a guide is retained remain. In this way, a guided tour for the is with the least amount of material and labor to achieve movable carrier, through the sharp-edged bends on the fixed carrier be avoided. Instead of continuous round bars, you can also provide individual round bar pieces at a distance from each other, which increases the amount of material and Weight is saved.

Die Zeichnung stellt die Erfindung in zwei Ausführungsbeispielen dar. Es zeigtThe drawing shows the invention in two exemplary embodiments represents. It shows

Fig. 1 eine Seitenansicht auf das vordere Ende eines Kranauslegers mit teilweise ausgefahrenem Teleskopträger,Fig. 1 is a side view of the front end of a crane boom with a partially extended Telescopic carrier,

Fig. 2 einen Querschnitt durch den Träger nach, der Linie IMI der Fig. 1,FIG. 2 shows a cross section through the carrier according to the line IMI of FIG. 1,

Fig. 3 eine andere Ausführungsform eines Trägers im Querschnitt undFig. 3 shows another embodiment of a carrier in cross section and

Fig. 4 einen vergrößerten Querschnitt durch eine Ecke des Teleskopträgers.4 shows an enlarged cross section through a corner of the telescopic support.

Nach der Ausführungsform der Fig. 1 und 2 besteht der Kranausleger aus zwei U-förmig profilierten Seitenblechen 1, 2, die eine Anzahl verhältnismäßig großer Öffnungen 3 haben, wobei die Ränder 4 dieser TeleskopauslegerAccording to the embodiment of FIGS. 1 and 2, the crane boom consists of two U-shaped profiled side plates 1, 2, which have a number of relatively large openings 3, the edges 4 of these telescopic booms

Öffnungen nach innen umgebördelt sind. Der gegenseitige Abstand der Seitenwandungen 1, 2 des Auslegers kann durch einzelne angeschweißte Abstandsbleche 5, 6 gewährleistet sein. Der ausschiebbare Teleskopträger 7 ist aus zwei U-Eisen 8, 9 an den Nähten 10 zusammengeschweißt.Openings are flanged inwards. The mutual spacing of the side walls 1, 2 of the boom can be ensured by individual welded spacer plates 5, 6. The extendable telescopic support 7 is made of two U-irons 8, 9 welded together at the seams 10.

In den Ecken sind längs dieser Ecken verlaufende Rundeisen 11 mittels seitlicher Schweißnähte 12 angeschweißt. Hierbei müssen die Schweißnähte so angeordnet sein, daß der größere Teil der außen liegenden Oberfläche der Rundeisen von der Schweißnaht nicht ergriffen ist, so daß die einwandfrei glatte Führung des Teleskopauslegers 7 im Inneren der Auslegerbleche, nicht gestört wird.In the corners are running along these corners Round iron 11 welded on by means of weld seams 12 on the side. Here the welds must be like this be arranged that the greater part of the outer surface of the round iron from the weld is not taken, so that the perfectly smooth guidance of the telescopic boom 7 inside the Cantilever plates, is not disturbed.

Bei der Ausführungsform der Fig. 3 sind vier Winkelbleche 15 vorgesehen, in deren Winkelraum die Winkeleisen 11 als Teleskopträger 7 geführt sind. Diese Winkeleisen, 15 werden durch Querbleche 16 und 17 miteinander verbunden.In the embodiment of Fig. 3 four angle plates 15 are provided, in the angular space Angle iron 11 are guided as a telescopic carrier 7. These angle irons 15 are supported by cross plates 16 and 17 connected to each other.
