Description

Teleskopierbarer KranauslegerTelescopic crane jib
Die Erfindung betrifft einen teleskopierbaren Kranausleger, mit einem rohrförmigen Basisauslegerkasten und mindestens einem Auslegerkasten, der innerhalb des Basisauslegerkastens teleskopierbar angeordnet ist, sowie einem Kopf mit Umlenkrollen am außenseitigen Ende des innersten Auslegerkastens.The invention relates to a telescopic boom, comprising a tubular base boom box and at least one boom box telescopically disposed within the base boom box, and a head having pulleys at the outboard end of the innermost boom box.
Stand der TechnikState of the art
Das Gesamtgewicht eines Mobilkrans mit Teleskopausleger, der für den öffentlichen Straßenverkehr zugelassen ist, wird durch die zulässige Achslast (z.B. 12 t in Deutschland) und der Anzahl der Achsen festgelegt. Teile des Krans, wie Gegengewicht und Hauptauslegerverlängerung, müssen oftmals getrennt transportiert werden, um innerhalb der zulässigen Achslasten zu bleiben. Auch die Länge des Teleskopauslegers, der aus biegesteifen Blechkästen besteht, schränkt die Transportmöglichkeiten und das maximal erlaubte Gewicht pro Einheit ein.The total weight of a mobile crane with a telescopic boom approved for use on public roads is determined by the permissible axle load (for example, 12 tonnes in Germany) and the number of axles. Parts of the crane, such as counterweight and main boom extension, often need to be transported separately to stay within allowable axle loads. The length of the telescopic boom, which consists of rigid sheet metal boxes, limits the transport possibilities and the maximum permissible weight per unit.
Der letzte Innenkasten, also der innerste Auslegerabschnitt, trägt am vorderen Ende einen Kopf mit einem Rollensatz zum Einscheren des Hubseils, zur Umlenkung des Hubseils (Einlaufrolle) und eventuell Befestigungspunkte für eine Hauptauslegerverlängerung sowie für eine Auslegerabspannung. Der Kopf ist in den Querschnitt des Kastens hineingebaut und verschließt diesen zum großen Teil durch Stahlbauteile und Montageteile, die außer durch komplette Demontage des Innenkastens nicht entfernt werden können.The last inner box, so the innermost boom section, carries at the front end a head with a roller set for cutting the hoist rope, for the deflection of the hoisting rope (inlet roller) and possibly attachment points for a main boom extension and for a boom bracing. The head is built into the cross-section of the box and largely closes it by steel components and mounting parts that can not be removed except by complete disassembly of the inner box.
Will man den Teleskopausleger durch zusätzliche Innenkästen verlängern, sind diese getrennt zu transportieren und auf der Baustelle zu montieren. Hierzu muss der bis dahin innerste Auslegerkasten mit dem Kopf zuerst entfernt werden. Anschließend muss ein Kasten ohne Kopf aber mit gleichem Querschnitt und vorderer Lagerung, ggf. mit zusätzlichen weiteren inneren Auslegerkästen, eingeschoben werden.If you want to extend the telescopic boom by additional inner boxes, these are to be transported separately and mounted on the site. For this, the hitherto innermost boom box must first be removed with the head. Subsequently, a box without a head but with the same cross-section and front storage, possibly with additional additional inner boom boxes inserted.
Nachteilig ist, dass man den innersten Auslegerkasten, mit dem daran angeordneten Kopf und dem zugehörigen Rollensatz erst demontieren muß, aber beim Langausleger nicht weiter verwenden kann, so dass für eine Verlängerung zwei Kästen mit gleichem Querschnitt benötigt werden. Ein Kasten bleibt nach der Verlängerung nutzlos übrig. Der Erfindung liegt die Aufgabe zugrunde, den Demontage- bzw. Montageaufwand bei einem Umbau eines Auslegers zu einem längeren Ausleger zu verringern und einen nach dem Umbau übrigbleibenden und an dieser Stelle überflüssigen Auslegerkasten zu vermeiden.The disadvantage is that you have to disassemble the innermost boom box, with the head arranged thereon and the associated set of rollers only, but can not continue to use the long boom, so that two boxes with the same cross section are needed for an extension. A box remains useless after the extra time. The invention has for its object to reduce the disassembly or assembly effort in a conversion of a boom to a longer boom and to avoid a remaining after the conversion and unnecessary at this point boom box.
Gelöst wird diese Aufgabe erfindungsgemäß bei einem teleskopierbaren Kranausleger mit einem rohrförmigen Basisauslegerkasten und mindestens einem Innenkasten, der innerhalb des Basisauslegerkastens teleskopierbar angeordnet ist, sowie einem Kopf mit Umlenkrollen am außenseitigen Ende des innersten Auslegerkastens dadurch, dass die Funktionen des Kopfes und der vorderen Lagerung am Ende dieses innersten Kastens in einen Rahmen integriert sind der am Außenumfang des Auslegerkastens derart angeordnet ist, dass alle zum Kopf gehörenden Teile außerhalb des freien Querschnittes des Auslegerkastens angeordnet sind und dass für eine Verlängerung des Auslegers mindestens ein weiterer Auslegerkasten in diesen Kasten einschiebbar ist. .This object is achieved according to the invention in a telescopic boom crane with a tubular base boom box and at least one inner box, which is telescopically disposed within the Basisauslegerkastens, and a head with pulleys at the outside end of the innermost boom box characterized in that the functions of the head and the front storage at the end this innermost box are integrated into a frame which is arranged on the outer circumference of the boom box such that all parts belonging to the head outside the free cross section of the boom box are arranged and that for extension of the boom at least one further boom box is inserted into this box. ,
An den einzuschiebenden Auslegerkästen kann mindestens ein weiterer Auslegerkopf befestigt sein.At least one additional boom head can be fastened to the boom boxes to be inserted.
Vorzugsweise ist der weitere Auslegerkopf am innersten Innenkasten befestigt.Preferably, the further boom head is attached to the innermost inner box.
Nach einer Ausgestaltung der Erfindung sind an dem innersten einzuschiebenden Auslegerkasten Befestigungspunkte für eine Hauptauslegerverlängerung vorhanden.According to one embodiment of the invention, attachment points for a main boom extension are present at the innermost boom box to be inserted.
Die Hauptauslegerverlängerung kann ein wippbarer Hilfsausieger sein oder ein Adapter für einen wippbaren Hilfsausieger.The main boom extension can be a tilting auxiliary ejector or an adapter for a teetering auxiliary ejector.
Nach einer weiteren Ausführung kann der Kopf mindestens eine Einlaufrolle aufweist, die schwenk-, schieb-oder montierbar so am Kopf angeordnet ist, dass sie den freien Querschnitt nicht beinträchtigt.According to a further embodiment, the head may have at least one inlet roller, which is pivotally, slidably mounted or mounted so arranged on the head that it does not affect the free cross section.
Möglich ist auch, dass der Kopf (1 ) mindestens eine Einlaufrolle aufweist, die schwenk-, schieb-oder montierbar so am Kopf angeordnet ist, dass sie in den freien Querschnitt durch Schwenken, Schieben oder Montieren einbringbar ist. Vorteilhaft ist es, wenn der Kopf aus miteinander verbundenen Querverbindungen besteht.It is also possible that the head (1) has at least one inlet roller, which is pivotally mounted, pushed or mounted so arranged on the head that it can be introduced into the free cross section by pivoting, pushing or mounting. It is advantageous if the head consists of interconnected cross connections.
Dabei kann an den Querverbindungen der Rollensatz angeordnet ist.It can be arranged on the cross connections of the roller set.
An den Querverbindungen können Befestigungspunkte für eine Auslegerabspannung angeordnet sein oder es können an den Querverbindungen Gabelköpfe als Befestigungspunkte für eine Auslegerverlängerung angeordnet sein.At the cross connections attachment points can be arranged for a boom bracing or it can be arranged as attachment points for a boom extension at the cross connections clevises.
Nach einer weiteren Ausgestaltung können beide Kopfrollensätze zur Einscherung einer Unterflasche benutzbar sein.According to a further embodiment, both head roller sets can be used for the shearing of a lower bottle.
Möglich ist aber auch, dass nur der Kopfrollensätze des äußeren Auslegerkastens zur Einscherung einer Unterflasche benutzbar ist.It is also possible, however, that only the head roller sets of the outer boom box can be used to shear a lower block.
Schließlich kann der Kopfrollensatz des inneren Auslegerkastens als Seilumlenkung dienen und es ist auch möglich, dass der Auslegerkopf lösbar am Auslegerkasten befestigt ist.Finally, the head roller set of the inner boom box can serve as a cable guide and it is also possible that the boom head is releasably secured to the boom box.

Fig.5 den durch eine erfindungsgemäße Ausführung erzielbaren Verlängerungszustand mit gleichzeitig möglichem Zweikopf/Zweihakenbetrieb.5 shows the attainable by an embodiment of the invention extension state with simultaneous possible two-head / two-hook operation.
Der Kopf 1 besteht aus einem tragenden Stahlbau der vollständig außerhalb des Querschnitts 2 des Auslegerkastens 3 angeordnet ist. Die Gabelköpfe 4,5, als Befestigungspunkte einer Hauptauslegerverlängerung, sind außerhalb der Kastenradien 6 angeordnet und jeweils horizontal und vertikal durch Querverbindungen 7 und 8 miteinander verbunden. Gleichzeitig sind sie in Längsrichtung 9 mit den Kastenradien 6 verbunden, um die Kräfte in den Auslegerkasten 3 einzuleiten.The head 1 consists of a load-bearing steel structure which is arranged completely outside the cross-section 2 of the jib box 3. The clevises 4, 5, as fastening points of a main boom extension, are arranged outside the box radii 6 and connected to each other horizontally and vertically by cross connections 7 and 8. At the same time they are connected in the longitudinal direction 9 with the box radii 6 to initiate the forces in the boom box 3.
An den unteren Gabelköpfen 4 sind Aufhängepunkte 10 für den Rollensatz 11 angeschlossen, dessen Kräfte über die vorhandenen Verbindungen zum Auslegerkasten 3 eingeleitet werden. Am hinteren Ende der oberen Gabelköpfe 5 kann jeweils links und rechts ein Abspannpunkt 12 für z. B. eine seitliche Auslegerabspannung angeordnet sein, dessen Kräfte ebenfalls über die vorhandenen Verbindungen in den Auslegerkasten 3 eingeleitet werden.At the lower fork heads 4 suspension points 10 are connected to the roller set 11, whose forces are introduced via the existing connections to the boom box 3. At the rear end of the upper fork heads 5 can each left and right a guy 12 for z. B. be arranged a lateral Auslegerabspannung whose forces are also introduced via the existing connections in the boom box 3.
Zwischen den oberen Gabelköpfen 5 ist mindestens eine Einlaufrolle 13 für den Rollensatz 11 angeordnet, die auch in der Breite verschieblich sein kann, um bei verschiedenen Einscherungen den Ablenkwinkel des Seils zu minimieren. Wenn diese Einlaufrolle 13 in den Querschnitt 2 hineinragt, ist sie durch Schieben, Drehen oder Wegheben aus dem Querschnitt zu bringen, um zusätzliche Innenkästen einschieben zu können. Es ist auch möglich die Einlaufrolle 13 außerhalb des Querschnittes 2 anzuordnen, so das sie aus diesem nicht entfernt werden muß.Between the upper fork heads 5 at least one inlet roller 13 is arranged for the roller set 11, which can also be displaced in width to minimize the deflection angle of the rope at different Einscherungen. If this inlet roller 13 protrudes into the cross section 2, it must be brought by pushing, turning or lifting out of the cross section in order to insert additional inner boxes can. It is also possible to arrange the inlet roller 13 outside of the cross section 2, so that they do not have to be removed from this.
In die Radien des Kastens 6, dessen Querschnitt 2 bis an das Ende des Kopfes erhalten bleibt, werden Gleitelemente 14 eingebaut.In the radii of the box 6, the cross section 2 is maintained up to the end of the head, sliding elements 14 are installed.
Die Gleitelemente 14 übernehmen die Führung und Lagerung des einzuschiebenden Innenkastens 15, wie dies bei Teleskopauslegern Stand der Technik ist. Die Querverbindungen 7,8 der Gabelköpfe 4,5 versteifen den Kastenquerschnitt 2, wodurch Lagerkräfte aufgenommen werden können.The sliding elements 14 take over the guidance and storage of the inner box 15 to be inserted, as is the case with telescopic jibs in the prior art. The cross connections 7.8 of the fork heads 4.5 stiffen the box cross-section 2, whereby bearing forces can be absorbed.
Ein weiterer erfindungsgemäßer Nutzen eines Teleskopauslegers mit zwei Auslegerköpfen, bei dem also ein Kopf am Auslegerende und ein weiterer Kopf an einem der anderen Auslegerkästen vorhanden ist, wird durch die Möglichkeit eines Zweihakenbetriebs zum Drehen von Lasten dargestellt. Another advantage of the invention of a telescopic boom with two boom heads, in which therefore one head is present at the boom end and another head on one of the other boom boxes is represented by the possibility of a two-hook operation for rotating loads.
