Description

Die Erfindung betrifft eine Zugstange für die Abspannung eines Kranauslegers gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a pull rod for the bracing of a crane boom according to the preamble of claim 1.

Kräne mit Kranauslegern sind z. B. aus der DE 20 2008 006 167 U1 bekannt. Die Kranausleger sind hier mit seilförmigen oder aus einzelnen, gelenkig miteinander verbundenen stangenförmigen Elementen abspannbar.Cranes with crane jibs are z. B. from the DE 20 2008 006 167 U1 known. The crane jibs are here with rope-shaped or from single, articulated interconnected rod-shaped elements braced.

Bei stangenförmigen als Zugstangen ausgeführten Elementen ist es bekannt, diese aus Rohrstücken mit an den Enden angeschweißten gabelförmigen Endstücken als Kupplungselemente auszuführen. Die einzelnen Zugstangen werden dann an den gabelförmigen Endstücken mittels einer Bolzenverbindung gelenkig in der erforderlichen Länge miteinander verkuppelt. Solche Zugstangen sind in DokumentIn the case of rod-shaped elements designed as tie rods, it is known to carry these out of pipe pieces with fork-shaped end pieces welded at the ends as coupling elements. The individual tie rods are then verkuppelt each other at the fork-shaped end pieces by means of a bolt connection in the required length. Such tie rods are in document

JP10194677 A offenbart. JP10194677 A disclosed.

Derartige beispielsweise als Gittermastkrane ausgeführten Krane unterliegen im laufenden Betrieb hohen dynamischen Beanspruchungen, die auch auf die Zugstangen der Abspannung einwirken.Such as running as a lattice cranes cranes are subject to high dynamic stresses during operation, which also act on the tie rods of the bracing.

Nachteilig bei geschweißten Zugstangen ist, dass die Schweißverbindungen zwischen Rohr und Kupplungselement eine erhöhte Kerbempfindlichkeit aufweisen und deshalb einer erhöhten Ermüdungsrissanfälligkeit im Schweißnahtbereich unterliegen. Die Dauerfestigkeit derartiger Zugstangen ist dadurch deutlich eingeschränkt, was zu frühzeitigem erhöhten Ausfallrisiko führt.A disadvantage of welded tie rods is that the welded joints between the pipe and the coupling element have an increased notch sensitivity and are therefore subject to increased fatigue crack susceptibility in the weld seam area. The fatigue strength of such tie rods is thus significantly limited, leading to premature increased risk of failure.

Aufgabe der Erfindung ist es, eine Zugstange für die Abspannung eines Kranauslegers anzugeben, die die beschriebenen Nachteile nicht aufweist und kostengünstig herstellbar ist.The object of the invention is to provide a pull rod for bracing a crane jib, which does not have the disadvantages described and is inexpensive to produce.

Diese Aufgabe wird nach dem Oberbegriff in Verbindung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand von Unteransprüchen.This object is achieved according to the preamble in conjunction with the characterizing features of claim 1. Advantageous developments are the subject of dependent claims.

Nach der Lehre der Erfindung sind der Rohrkörper und das Kupplungselement unter Verzicht einer stoffschlüssigen Verbindung lösbar miteinander verbindbar, wobei der Bereich der Verbindung so bemessen und kerbarm gestaltet ist, dass rechnerisch die volle Tragfähigkeit des Rohrquerschnitts im Hinblick auf eine möglichst hohe Dauerfestigkeit ausgenutzt werden kann.According to the teachings of the invention, the tubular body and the coupling element are detachably connectable with waiving a cohesive connection, wherein the region of the compound is so dimensioned and kerbarm designed that mathematically the full capacity of the tube cross-section can be exploited in terms of maximum fatigue strength.

In einer ersten Ausgestaltung der Erfindung ist die Verbindung eine Verschraubung. Der Rohrkörper weist im Verbindungsbereich eine mit einem Gewinde versehene Wandverdickung auf, die so bemessen ist, dass eine für die Berechnung der Tragfähigkeit des Rohrkörpers zu berücksichtigende Querschnittsschwächung der Nennwanddicke des Rohres durch das Gewinde im Verbindungsbereich von Rohrkörper und Kupplungselement vermieden wird und der Übergang von der Wandverdickung zum Rohrkörper kerbarm ausgeführt ist.In a first embodiment of the invention, the connection is a screw connection. The tubular body has in the connection area a threaded wall thickening, which is dimensioned such that a to be considered for the calculation of the load capacity of the tubular body cross-sectional weakening of the nominal wall thickness of the tube is avoided by the thread in the connection region of the tubular body and coupling element and the transition from the Wall thickening to the tubular body kerbarm is executed.

In einer weiteren Ausgestaltung der Erfindung weist die gelenkige Verkupplung der Zugstangen untereinander und die Verbindung des Rohrkörpers mit dem Kupplungselement eine gemeinsame formschlüssige Verbindung als Bolzenverbindung auf. Hierbei sind die Enden des Rohrkörpers mit einer nach außen weisenden Wandverdickung versehen, an deren schulterförmigen Übergangsbereichen vom Rohrkörper zur Wandverdickung darauf aufsteckbare Kupplungselemente für eine Zugkraftübertragung formschlüssig anliegen, dabei sind das Kupplungselement eines Endes als Vaterelement und das für das andere Ende als Mutterelement ausgeführt, wobei das Vaterelement der einen Zugstange mit dem Mutterelement der anderen Zugstange ineinander einsteckbar und im Überdeckungsbereich mittels eines Bolzens miteinander verbindbar sind.In a further embodiment of the invention, the articulated coupling of the tie rods with each other and the connection of the tubular body with the coupling element on a common form-fitting connection as a bolt connection. Here, the ends of the tubular body are provided with an outwardly facing wall thickening, abut on the shoulder-shaped transitional areas of the tubular body for wall thickening attachable coupling elements for a tensile force transfer, while the coupling element of one end as the father element and the other end designed as a nut member, said the father element of a pull rod with the nut element of the other pull rod are inserted into one another and connectable in the overlapping area by means of a bolt.

Der Vorteil der erfindungsgemäßen kraft- bzw. formschlüssigen Verbindung von Rohrkörper und Kupplungselement besteht darin, dass einerseits durch den Verzicht auf eine stoffschlüssige Verbindung durch Schweißen dadurch bedingte Materialinhomogenitäten, wie z. B. metallurgische Kerben in der Verbindung, die sich negativ auf die Dauerfestigkeit auswirken, vermieden werden. Andererseits ist sowohl die kraftschlüssige Schraubverbindung von Rohrkörper und Kupplungselementen als auch die formschlüssige Verbindung über aufsteckbare Kupplungselemente vorteilhaft lösbar ausgeführt, so dass eine verschleißbedingte Reparatur oder der Austausch der Kupplungselemente sehr einfach und kostengünstig möglich sind.The advantage of the non-positive or positive connection of tubular body and coupling element according to the invention is that on the one hand by the waiver of a cohesive connection by welding consequent material inhomogeneities such. As metallurgical notches in the compound, which adversely affect the fatigue strength, can be avoided. On the other hand, both the non-positive threaded connection of tubular body and coupling elements and the positive connection via attachable coupling elements are advantageously carried out detachable, so that a wear-related repair or replacement of the coupling elements are very simple and inexpensive possible.

Erfindungsgemäß wird die Wandverdickung in einer ersten vorteilhaften Verfahrensvariante durch ein Aufstauchen insbesondere durch Warmstauchen des Rohrendes erzeugt.According to the invention, the wall thickening is produced in a first advantageous variant of the method by upsetting in particular by hot upsetting of the pipe end.

Der Stauchvorgang wird dabei vorteilhaft so ausgeführt, dass die beim Stauchen erzeugten Übergänge vom Rohr zum Kupplungsstück möglichst kerbarm sind. Hierzu weisen diese einen möglichst großen Radius auf. Falls erforderlich, können die Übergänge auch durch eine mechanische Bearbeitung erzeugt werden.The upsetting process is advantageously carried out so that the transitions generated during compression from the pipe to the coupling piece are kerbarm as possible. For this purpose, they have the largest possible radius. If necessary, the transitions can also be created by mechanical processing.

Die derart gestalteten Übergänge mit einem fließenden und kerbfreien Übergang zum nicht verdickten Bereich des Rohres gewährleisten vorteilhaft in der Übergangszone einen niedrigen Spannungskonzentrationsfaktor, der sich günstig auf die Dauerfestigkeit des Rohrkörpers auswirkt.The thus designed transitions with a flowing and notch-free transition to the non-thickened region of the tube advantageously ensure in the transition zone a low stress concentration factor, which has a favorable effect on the fatigue strength of the tubular body.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist es auch möglich, die Wandverdickung des Rohrendes durch eine Auftragsschweißung oder durch Aufsintern zu realisieren und anschließend mechanisch zu bearbeiten.According to a further advantageous embodiment of the invention, it is also possible to realize the wall thickening of the pipe end by a build-up welding or by sintering and then to work mechanically.

Bei den vorgenannten Verfahrensvarianten wird die Erzeugung der Wandverdickung vollständig vom Walzprozess abgekoppelt; dies hat den Vorteil, dass Rohre, wie z. B. Lagerrohre, die ursprünglich nicht für den beschriebenen Einsatzzweck vorgesehen waren, nachträglich mit einer Wandverdickung und einer entsprechenden mechanischen Bearbeitung versehen werden können.In the aforementioned process variants, the production of the wall thickening is completely decoupled from the rolling process; This has the advantage that pipes such. B. bearing tubes, which were not originally intended for the application described, can be subsequently provided with a wall thickening and a corresponding mechanical processing.

Es ist außerdem möglich, die Rohrendenverdickung bereits bei der Herstellung des warmgewalzten nahtlosen Rohres zu erzeugen, wenn es aus fertigungstechnischer Sicht vorteilhafter erscheint. Beispielsweise wird durch ein Auseinanderfahren der Walzen an den Rohrenden ein vergrößerter Außendurchmesser erzeugt und ein vergrößerter Innendurchmesser z. B. durch ein entsprechend konstruiertes Innenwerkzeug.It is also possible to produce the pipe end thickening already in the production of the hot-rolled seamless pipe, if it appears more advantageous from a production point of view. For example, by moving apart of the rollers at the tube ends produces an enlarged outer diameter and an enlarged inner diameter z. B. by a correspondingly constructed inner tool.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung von dargestellten Ausführungsbeispielen.Further features, advantages and details of the invention will become apparent from the following description of illustrated embodiments.

In dieser Position werden dann die Kupplungselemente 6 und 7 auf dem Rohrkörper 2 beispielsweise durch einen Schweißpunkt oder durch eine Passfeder fixiert.To mount the coupling elements 6 and 7, these must be aligned and fixed after screwing on the tubular body 2, that the holes of the coupling elements 6 and 7 for insertion of the bolt 8 are exactly aligned. In this position, the coupling elements 6 and 7 are then fixed on the tubular body 2, for example by a welding point or by a feather key.

Der Rohrkörper 2 weist an den Enden jeweils eine Wandverdickung 3 auf, die mit einem Außengewinde 5 versehen ist, welches mit einem im Kupplungselement 6 bzw. 7 angebrachten Innengewinde 5' korrespondiert. Die Übergänge 4 von der Wandverdickung 3 zum Rohrkörper 2 sind erfindungsgemäß ansatzfrei und kerbarm ausgeführt, um eine möglichst hohe Dauerfestigkeit der Zugstange 1 im Betrieb zu erreichen.The tubular body 2 has at the ends in each case a wall thickening 3, which is provided with an external thread 5, which corresponds with a mounted in the coupling element 6 and 7 internal thread 5 '. The transitions 4 of the wall thickening 3 to the tubular body 2 are inventively ropeless and kerbarm executed to achieve the highest possible fatigue strength of the tie rod 1 during operation.

Die Kupplungselemente 9, 10 sind erfindungsgemäß symmetrisch zur Achse des Rohrkörpers 2' zweischalig geteilt ausgeführt, um die Montage auf die Rohrenden zu ermöglichen.In order to transmit tensile forces on the tie rod 1 ', the ends of the tubular body 2' are provided with outwardly facing wall thickening 3 ', at the shoulder-shaped transitional areas 11 from the tubular body 2' to the wall thickening 3 'thereon clip-on coupling elements 9, 10 for a tensile force transfer fit , The coupling elements 9, 10 are according to the invention symmetrical to the axis of the tubular body 2 'clamshell split executed to allow mounting on the pipe ends.

Zum Verbinden der Zugstangen 1' miteinander, ist das Kupplungselement 9 des einen Endes als Vaterelement und das Kupplungselement 10 des anderen Endes der Zugstange 1' als Mutterelement ineinander einsteckbar ausgeführt und mit einer Durchgangsbohrung zum Einstecken des Bolzens 12 versehen.To connect the tie rods 1 'together, the coupling element 9 of one end is designed as a father element and the coupling element 10 of the other end of the tie rod 1' as a nut element plugged into each other and provided with a through hole for insertion of the bolt 12.
