Description

Die Erfindung bezieht sich auf eine als Transport- und Montageeinheit ausgebildete Turmspitze eines oben drehenden Baukrans, dessen Ausleger mittels Seileinziehwerk ein- und auswippbar ist, mit einer oder mehreren, an der Spitze der Turmspitze angeordneten, der Umlenkung des Wippseils dienenden Seilrollen.The invention relates to a spire designed as a transport and assembly unit of an overhead rotating construction crane, the jib of which can be luffed in and out by means of a rope pulling-in device, with one or more rope pulleys which are arranged at the top of the spire and serve to deflect the luffing rope.

Es ist ein oben drehender, eine Turmspitze, einen Ausleger und einen Gegenausleger aufweisender Baukran bekannt, bei dem das Ein- und Auswippen des Auslegers mit einem Seileinziehwerk (Wippwerk) erfolgt, das auf dem Gegenausleger bzw. im sich hinter der Turmspitze befindlichen Maschinenhaus angeordnet ist. Bisher wurden für den Turmkopf die Turmspitze, der Gegenausleger/Maschinenhaus und der im Betriebszustand des Krans an der Hauptabspannung des Auslegers befestige Rollenblock als getrennte Einheiten zum Kranaufstellungort transportiert. Da das Auslegereinziehwerk am Gegenausleger, Umlenkrollen an der Turmspitze und der Rollenblock an der Hauptabspannung angeordnet sind, konnte das Einscheren des Wippseils nicht im Herstellerwerk, sondern nur manuell an der Baustelle vorgenommen werden. Die manuelle Seileinscherung an der Baustelle ist jedoch anstrengend und erhöht die Montagezeit. Der Erfindung liegt daher die Aufgabe zugrunde, eine Turmspitze der eingangs genannten Art so zu gestalten, daß der Turmkopf des Baukrans an der Baustelle in relativ kurzer Zeit montiert bzw. demontiert werden kann.A top-rotating construction crane is known, which has a spire, a jib and a counter-jib, in which the jib is swiveled in and out with a rope pull-in mechanism (luffing mechanism) which is arranged on the counter-jib or in the machine house located behind the spire . So far, the tower top, the counter jib / machine house and the roller block attached to the main guying of the boom in the operating state of the tower were transported as separate units to the crane installation site. Since the jib pull-in mechanism is arranged on the counter jib, deflection rollers on the top of the tower and the roller block on the main guying, the rocking rope could not be reeved in at the manufacturer's plant, but only manually at the construction site. However, manual rope reeving at the construction site is exhausting and increases the assembly time. The invention is therefore based on the object to design a spire of the type mentioned in such a way that the tower head of the construction crane can be assembled or disassembled at the construction site in a relatively short time.

Diese Aufgabe wird erfindungsgemäßdadurch gelöst, daß das mit dem Wippseil versehene Seileinziehwerk an einem Träger der Turmspitze befestigt ist, daß das Wippseil über die Umlenkrolle bzw. Umlenkrollen an der Spitze der Turmspitze und eine oder mehrere, in einem Träger gelagerte, weitere Umlenkrollen zur Spitze der Turmspitze geführt und dort befestigt ist, und daß der Träger der Umlenkrollen mit der Turmspitze fest, jedoch lösbar, verbunden ist.This object is achieved according to the invention in that the rope pulling device provided with the luffing rope is fastened to a carrier of the tower top, that the luffing rope over the deflection roller or deflection rollers at the top of the tower top and one or more further deflection rollers mounted in a carrier to the top of the tower The spire is guided and fastened there, and that the support of the deflection rollers is firmly but releasably connected to the spire.

Bei der erfindungsgemäßen Turmspitze mit integriertem Einziehwerk werden das Wippseil bereits im Herstellerwerk maschinell eingeschert und die Turmspitze mit dem an ihr fixierten Rollenblock zur Baustelle transportiert. Die Montage bzw. Demontage des Turmkopfes an der Baustelle ist relativ einfach und zeitsparend.In the case of the tower top according to the invention with an integrated retracting mechanism, the luffing rope is already mechanically reeved in the manufacturing plant and the tower tip is transported to the construction site with the roller block attached to it. The assembly or disassembly of the tower head at the construction site is relatively simple and time-saving.

Die Turmspitze weist ein Unterteil 1a, einen Drehrahmen 1b mit Drehwerk und ein in Richtung eines Gegenauslegers 2 schräg stehendes, in Fachwerkbauweise ausgeführtes Maststück 1c auf. Das Maststück 1c ist in seinem unteren Bereich mit einem waagrechten Träger 3 versehen, der zwischen den oberen und unteren Längsholmen 4a, 4b verläuft und mit diesen fest verbunden ist. Auf dem Träger 3 ist das Ausleger-Einziehwerk 5 befestigt, das im wesentlichen aus einer Seiltrommel 6 und derem motorischen Antrieb besteht. Auf der Seiltrommel 6 ist ein Wippseil 7 befestigt, das unter mehrfacher Seileinscherung über - beispielsweise vier-- Umlenkrollen 8 an der Spitze der Turmspitze 1 und weitere - beispielsweise vier - Umlenkrollen 9, zu einem Festpunkt 11 an der Spitze der Turmspitze geführt ist. Die Umlenkrollen 8, 9 sind je auf einer gemeinsamen waagrechten Achse gelagert und über ihre Achsen in entsprechenden Ausnehmungen ihrer Tragkonstruktion abgestützt. Die Tragkonstruktion der Umlenkrollen 8 und das Einziehwerk 5 sind sowohl im Transport- und Montagefall als auch im Betriebszustand des Krans mit der Turmspitze verbunden.The top of the tower has a lower part 1a, a rotating frame 1b with rotating mechanism and a mast piece 1c, which is inclined in the direction of a counterjib 2 and is constructed in a half-timbered construction. The mast section 1c is provided in its lower region with a horizontal support 3 which runs between the upper and lower longitudinal spars 4a, 4b and is firmly connected to them. On the carrier 3, the boom pull-in mechanism 5 is fastened, which essentially consists of a cable drum 6 and its motor drive. On the cable drum 6, a seesaw rope 7 is fastened, which, with multiple rope reeving, is guided to a fixed point 11 at the top of the tower top by - for example four - guide rollers 8 at the top of the tower tip 1 and further - for example four - guide rollers 9. The deflection rollers 8, 9 are each mounted on a common horizontal axis and supported on their axes in corresponding recesses in their supporting structure. The supporting structure of the deflection rollers 8 and the pull-in mechanism 5 are connected to the top of the tower both in the case of transport and assembly and in the operating state of the crane.
