Abstract
Description
Die Erfindung betrifft die Verwendung einer Buchse bei der Verbindung von Turmelementen eines Turmkrans.The The invention relates to the use of a socket in the connection of tower elements of a tower crane.
Turmkrane
umfassen eine Kranbasis, von der ausgehend sich ein Turm nach oben
erstreckt. An einem oberen Abschnitt des Turms ist üblicherweise ein
Ausleger und möglicherweise
ein Gegenausleger angebracht. Turmkrane sind zum Beispiel aus der Patentschrift
Der Turm eines Turmkranes umfasst üblicherweise mehrere Turmelemente (auch als „Turmschüsse" bezeichnet). Die Turmelemente können beispielsweise 4,5m lang und 2,5t schwer sein. Die vertikal verlaufenden Eckstiele der Turmelemente werden formschlüssig aufeinander gesetzt und lösbar mittels Bolzen verbunden. Diese Bolzenverbindung wird dadurch ermöglicht, dass die Enden der Eckstiele der Turmelemente jeweils Zapfen bzw. Hülsen zur Zapfenaufnahme aufweisen, die bei der Montage ineinander gesteckt werden können. Die Zapfen und die Hülsen zur Aufnahme der Zapfen können dabei mit zueinander ausgerichteten, durchgehenden und im wesentlichen zylindrischen, durchmessergleichen Öffnungen versehen sein, in die jeweils ein im wesentlichen zylindrischer Bolzen eingepasst wird. Ein Turmelement kann an seinem einen Ende nur Hülsen und an dem anderen Ende nur Zapfen aufweisen.Of the Tower of a tower crane usually includes several tower elements (also referred to as "tower shots") 4,5m long and 2,5t heavy. The vertical corner handles The tower elements are form-fitting put on each other and detachable connected by bolts. This bolt connection is thereby made possible that the ends of the corner posts of the tower elements each pin or sleeves have to pin receiving, which plugged into each other during assembly can be. The cones and the sleeves for receiving the pin can doing so with aligned, continuous and substantially cylindrical, equal diameter openings be provided in each fitted with a substantially cylindrical bolt becomes. A tower element can at its one end only sleeves and have only pins at the other end.
Die Öffnungen (Bohrungen) in den Zapfen und Hülsen der Turmelemente werden durch die starken Kräfte, die auf sie wirken, und die ständig wechselnde Beanspruchung im Laufe der Zeit möglicherweise größer (schlagen aus), bis schließlich die zulässige Toleranzgrenze erreicht wird.The openings (Holes) in the pins and sleeves The tower elements are characterized by the strong forces that act on them, and the constantly changing stress may increase over time (beat out), until finally the permissible Tolerance limit is reached.
Im Falle stärkerer Vergrößerungen der Öffnungen (Bohrungen) ist es bekannt, die Öffnungen in den Eckstielen zuzuschweißen und neu zu bohren. Dies hat jedoch den Nachteil, dass es sehr zeitaufwändig ist, insbesondere, da es sich bei Bohren und Schweißen um völlig verschiedene Tätigkeiten handelt, die von verschiedenen Fachleuten ausgeführt werden. Bekannt ist weiterhin, die ausgeschlagenen Öffnungen auszubohren, also die Öffnungen zu vergrößern, mit der Folge, dass es Turmelemente mit verschieden großen Öffnungen (Bohrungen) gibt. Die Öffnungen von Turmelementen können jedoch auch von vorneherein unterschiedlich groß sein, weil sie beispielsweise zu unterschiedlichen Generationen von Turmelementen gehören. Zur Verbindung solcher Turmelemente mit verschieden großen Bohrungen ist es bekannt, ein Adapter-Turmelement vorzuhalten, dessen eines Ende mit den Turmelementen mit den kleineren Bohrungen und des anderes Ende mit den Turmelementen mit den größeren Bohrungen zusammenpasst. Diese Lösung hat jedoch insbesondere den Nachteil, dass sie erheblichen logistischen Aufwand erfordert, damit das Adapter-Turmelement dorthin gelang, wo es gebraucht wird.in the Trap stronger enlargements the openings (Holes) it is known the openings To weld in the corner stems and re-drill. However, this has the disadvantage that it is very time consuming especially since drilling and welding involve completely different activities traded by various professionals. It is also known the knocked-out openings to drill out, so the openings to enlarge, with the consequence that there are tower elements with different sized openings (Holes) there. The openings of tower elements can However, from the outset be different sizes, because, for example belong to different generations of tower elements. to Connection of such tower elements with different sized holes It is known to hold an adapter tower element, one of which End with the tower elements with the smaller holes and the other one End with the tower elements with the larger holes mates. This solution However, in particular has the disadvantage that they require considerable logistical effort required for the adapter tower element to get where it needed to becomes.
Der Erfindung liegt die Aufgabe zugrunde, Turmelemente mit verschieden großen Bohrungen zu verbinden und dabei die Nachteile der bekannten Lösungen zu vermeiden.Of the Invention is based on the object, tower elements with different huge To connect holes and thereby the disadvantages of the known solutions avoid.
Diese Aufgabe wird durch die Verwendung einer Buchse mit den im Patentanspruch 1 bezeichneten Merkmalen gelöst. Patentanspruch 4 betrifft einen Turmkran, bei dem eine Buchse nach Patentanspruch 1 verwendet wird. Weitere Ausführungsformen sind Gegenstand der Unteransprüche oder nachfolgend beschrieben.These Task is by the use of a socket with the in claim 1 designated features solved. Claim 4 relates to a tower crane, in which a socket after Claim 1 is used. Other embodiments are the subject the dependent claims or described below.
Die Buchse hat vorzugsweise als Innendurchmesser (innerhalb der Toleranzgrenzen) den Durchmesser der Öffnungen in den Hülsen des einen Turmelements (mit den kleineren Bohrungen) und als Außendurchmesser den Durchmesser der Öffnungen in den Zapfen des anderen Turmelements (mit den größeren Öffnungen). Die Buchse besteht vorzugsweise aus einem hochwertigen Material, ganz besonders vorteilhafterweise aus dem gleichen Material wie die verwendeten Bolzen, vorzugsweise hochwertigem Stahl wie beispielsweise legiertem 42 CrMo 4. Die Buchse weist bevorzugt an einem Ende einen nach außen überstehenden Bund auf, der sie gegen ein Verschieben zu weit in die Bohrung hineinsichert. Die Buchse wird in den Zapfen mit der größeren Öffnung hineingeschoben.The Socket preferably has inner diameter (within tolerance limits) the diameter of the openings in the sleeves one of the tower elements (with the smaller holes) and the outside diameter the diameter of the openings in the cones of the other tower element (with the larger openings). The bushing is preferably made of a high quality material, most advantageously from the same material as the bolts used, preferably high-quality steel such as alloyed 42 CrMo 4. The socket preferably has one end protruding outwards Covenant, which insures against moving too far into the hole. The bush is pushed into the pin with the larger opening.
Die Buchse lässt sich auch nach Jahren wieder ausbauen, sie kann mittels eines einfachen Werkzeugs ausgeschlagen werden. Die Zapfen des Turmelements sind immer oben, während die Hülsen unten angeordnet sind und über die Zapfen des unteren Turmelementes geschoben werden.The Socket leaves can expand even after years, it can by means of a simple tool be knocked out. The cones of the tower element are always up, while the sleeves down are arranged and over the pins of the lower tower element are pushed.
Mit der Erfindung wird auch ein Verfahren zur Reparatur einer ausgeschlagenen Öffnung in dem Zapfen eines Turmelements eines Turmkrans zur Verfügung gestellt, bei dem die Öffnung in dem Zapfen aufgebohrt wird, so dass sie eine zylindrische Form mit vergrößertem Durchmesser erhält, und anschließend eine Buchse in die Öffnung geschoben wird, deren Innendurchmesser dem ursprünglichen Innendurchmesser der Öffnung entspricht. Die erfindungsgemäße Lösung hat den Vorteil, dass das Schweißen völlig entfällt.The invention also provides a method of repairing a worn opening in the journal of a tower element of a tower crane, in which the opening in the journal is drilled so as to obtain a cylindrical shape of increased diameter, and then a bush in the Opening pushed whose inner diameter corresponds to the original inner diameter of the opening. The solution according to the invention has the advantage that welding is completely eliminated.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben:One embodiment The invention is illustrated in the drawing and will be described below described in more detail:
