Description
Es ist bereits bekannt, bei fahrbaren Drehkranen, insbesondere bei Eisenbahndrehkranen, für eine gleichmäßige Verteilung der Raddrucke zu sorgen. Zu diesem Zweck: hat man bewegliche Gegengewichte angebracht, die in Abhängigkeit von der Stellung des Kranes gesteuert werden. Die Anordnung dieser Gewichte in oder auf dem Unterwagen bedingt eine große Baulänge des Unterwagens, und der Kran kann in Gleisrichitung nur bei großer Ausladung arbeiten. Man hat die Gegengewichte auch schon auf dem Oberwagen untergebracht. Gemäß der Erfindung wird nun der ganze obere Teil des Kranes zur Beeinflussung der Raddrucke herangezogen. It is already known, in mobile slewing cranes, in particular in railway slewing cranes, to ensure an even distribution of the wheel pressures. To this end: has movable counterweights are attached, depending on the position of the Crane can be controlled. The arrangement of these weights in or on the undercarriage requires a large overall length of the undercarriage, and the crane can be in the track direction only work with a large overhang. You already have the counterweights on the Housed superstructure. According to the invention, the entire upper part of the Crane used to influence the wheel pressures.
Die Erfindung besteht darin, daß. der direhbare Oberwagen in 'ein drehbares Untergestell und in ein auf diesem verfahrbares:, den Ausleger tragendes Gestell unterteilt ist.The invention consists in that. the directable superstructure in 'a rotatable underframe and into a movable one on this: the boom supporting frame is divided.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar ein
Eisenhahndrehkran, der in Eiaenbahnzügen
eingestellt wird. Es zeigen:
Abb. ι den Kran in Arbeitsstellung und
AbD. 2 denselben im Beförderungszustand. Der fahrbare Drehkran besteht aus einem
Laufwagen α mit einem Schienenkranz für den drehbaren Teil. Das Untergestell & des
drehbaren Oberwagens läuft mit Drehrollen c auf dem Scbienenkranz des Lauf wagens α und
wird durch den Drehzapfen// geführt. Auf diesem drehbaren Untergestell läßt sich das
Oberteil e mit dem einseitig vorgesehenen Gegengewicht / denart verschieben, daß der
Schwerpunkt in die Drehachse 'des Krans bzw. Mitte des Wagens zu liegen kommt.In the drawing, an embodiment of the invention is shown, namely a rotary crane that is set in railway trains. Show it:
Fig. Ι the crane in working position and
AbD. 2 the same in the state of transport. The mobile slewing crane consists of a carriage α with a rail ring for the rotating part. The underframe & of the rotating superstructure runs with rotating rollers c on the trunnion of the carriage α and is guided by the pivot //. On this rotatable base frame, the upper part e with the counterweight provided on one side can be moved in such a way that the center of gravity comes to lie in the axis of rotation of the crane or in the middle of the carriage.
Es ist selbstverständlich, daß' die Anordnung· nach der Erfindung auch bei Drehkranen angeordnet werden kann, die keinen Unterwiagen besitzen, z. B. bei Drehkranen auf Fundamenten, auf Schwimmkähnen o. dgl. zur Erreichung gleichmäßiger Auflagerkräfte.It goes without saying that 'the arrangement according to the invention can also be arranged in slewing cranes that have no undercarriages own, e.g. B. for slewing cranes on foundations, on floating boats o Achievement of uniform support forces.
