Abstract

The boom part has lower-, right-, and left framework sections (I-III) flexibly connected with each other, where all joints (A-C) between the framework sections are releasable to fold the boom part together. The framework sections are disassembled into three pieces and exhibit a square cross-section.

Description

Die Erfindung betrifft den Ausleger eines Turmdrehkranes. Dieser Ausleger wird in der Regel in Teilstücken ausgeführt, wovon jedes einen dreieckigen Querschnitt aufweist. Dieser Querschnitt wird durch die Verbindung dreier Fachwerkebenen in den Eckpunkten erreicht. Hierzu werden an den drei Gurten die Diagonalen fest angeschlossen.The The invention relates to the boom of a tower crane. This boom is usually in sections executed each of which has a triangular cross-section. This cross section becomes by connecting three truss levels in the vertices reached. For this purpose, the diagonals are firmly connected to the three straps.

Bei der beschriebenen Erfindung werden nun diese Anschlüsse zwischen den Fachwerkebenen gelenkig bzw. mindestens eine auch lösbar hergestellt. Hierdurch lässt sich das Auslegerteilstück falten und die drei Fachwerkebenen kommen nahezu parallel zu liegen. Bei entsprechenden Abmessungen lässt sich so auch ein Auslegerteilstück in einem anderen Teilstück, gleicher Breite, verwahren.at The described invention now these connections between the truss levels articulated or at least one made detachable. This leaves Fold the boom section and the three truss levels are nearly parallel. at corresponding dimensions leaves so also a boom section in another section, same width, safekeeping.

Werden alle drei Gelenke des Auslegerteilstücks lösbar hergestellt lässt sich das Auslegerteilstück auch komplett zerlegen.Become All three joints of the boom section can be made detachable the boom section also disassemble completely.

Stand der Technik:State of the art:

Es ist bekannt bei Turmdrehkranen den Ausleger in einzelne Teilstücke zu unterteilen. Die Auslegerteilstücke sind mit dreieckigem Querschnitt gefertigt, wobei in drei Ebenen Fachwerkverbände angeordnet werden.It is known in tower cranes to divide the boom into individual sections. The boom sections are made with triangular cross-section, being in three levels Timbered Associations to be ordered.

Die drei Gurte in den Eckpunkten sind in der Regel viereckig im Querschnitt, die beiden unteren stellen gleichzeitig die Laufbahn für die Laufkatze dar. Die Verbände werden in der Regel als Rohr ausgeführt und auf die Ecken der Gurte geschweißt.The three straps in the corner points are usually quadrangular in cross-section, the two lower represent at the same time the career for the trolley. The bandages are usually designed as a tube and on the corners of the straps welded.

Es ist bekannt, dass Auslegerteilstücke in unterschiedlicher Breite und Höhe gefertigt werden, damit sich ein Teilstück im nächst größeren verwahren und transportieren lässt. Hierfür ist eine entsprechende Laufkatze mit mindestens zwei unterschiedlichen Spurbreiten erforderlich, da die Laufrolle der Laufkatze auf den Gurten des unteren Fachwerksverbands fährt.It it is known that boom sections be manufactured in different width and height, so a section in the next keep larger and transport. Therefor is a corresponding trolley with at least two different ones Track riding required because the caster of the trolley on the Belts of the lower truss association drives.

Beschreibung der Erfindung:Description of the invention:

Die Erfindung ist in den Zeichnungen an Hand eine Systemskizze dargestellt. Sie beschränkt sich nicht auf die dargestellte Ausbildungsform, vielmehr sind weitere, im Rahmen der Erfindung liegende Abwandlungen möglich.The The invention is illustrated in the drawings with reference to a system sketch. She limits herself not to the illustrated training, but more, Variations within the scope of the invention possible.

1 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks in geschlossener Form. In dieser Form kann das Teilstück am Turmdrehkran montiert und der Turmdrehkran damit betrieben werden. 1 shows the cross section of a boom section of the invention in a closed form. In this form, the section can be mounted on the tower crane and the tower crane operated with it.

2 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks mit am Punkt (I) geöffnetem Gelenk. Durch Anheben am Punkt (II) kann nun die untere Fachwerkebene in die Vertikale bewegt werden. 2 shows the cross section of a boom section according to the invention with at the point (I) open joint. By lifting at point (II), the lower truss level can now be moved to the vertical.

3 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks, bei dem die untere Fachwerkebene durch Anheben am Punkt (II) auf dem Weg der Klappbewegung in die Vertikale ist. 3 shows the cross section of a boom section according to the invention, in which the lower truss level is by lifting at the point (II) on the way the folding movement in the vertical.

4 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks in zusammengeklappter Form. In dieser Form kann das Auslegerteilstück platzsparend verwahrt und transportiert werden. Außerdem kann das Teilstück in dieser Form in einem weiteren (geschlossenen) Auslegerteilstück gleicher Breite verwahrt bzw. transportiert werden. 4 shows the cross section of a boom section according to the invention in collapsed form. In this form, the boom section can be stored and transported to save space. In addition, the section can be stored or transported in this form in another (closed) boom section of equal width.

5 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks in geschlossener Form in isometrischer Darstellung. Diese entspricht dem Sinn nach 1. 5 shows the cross section of a boom section according to the invention in a closed form in an isometric view. This corresponds to the sense 1 ,

6 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks in gefalteter Form in isometrischer Darstellung. Diese entspricht dem Sinn nach 4. 6 shows the cross section of a boom section of the invention in folded form in isometric view. This corresponds to the sense 4 ,

7 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks in zerlegter Form. Hierbei werden an allen Eckpunkten die Gelenke geöffnet und die drei einzelne Fachwerkebenen können nach belieben gestapelt werden. 7 shows the cross section of a boom segment according to the invention in a disassembled form. Here, the joints are opened at all vertices and the three individual truss levels can be stacked as desired.

8 zeigt den Querschnitt eines erfindungsgemäßen Auslegerteilstücks gefaltet und in einem höheren Auslegerstück gleicher Breite verwahrt. 8th shows the cross section of a boom section according to the invention folded and stored in a higher boom piece of equal width.

Vorteile:Advantages:

  • • Durch das Falten der Auslegerteilstücke können diese platzsparend verwahrt und transportiert werden. Hierdurch werden weniger Fahrzeuge für den Transport des Krans auf die Baustelle benötigt. Auch die Lagerung des Krans kann platzsparender realisiert werden.• By the folding of the boom sections can this to save space and to be transported. This will be fewer vehicles for the Transportation of the crane to the construction site needed. Also the storage of the Cranes can be realized in a space-saving way.
  • • Da bei Auslegern von Turmdrehkranen oft eine Abstufung in der Höhe des Querschnitts erfolgt kann eines der vorderen Auslegerteilstücke in einem der hinteren Auslegerteilstücke, gleicher Auslegerbreite verwahrt oder transportiert werden.• There For cranes of tower cranes often a gradation in the height of the cross section can take place one of the front boom sections in one of the rear boom sections, same boom width stored or transported.
  • • Durch das Zerlegen der Auslegerteilstücke kann, z. B. bei Transport in einem Container, der vorhandene Platz optimaler ausgenutzt werden.• By the dismantling of the boom sections can, for. B. when transported in a container, the existing space be used optimally.
