Description

Die Erfindung bezieht sich auf Tragrollen für Drehkränze, insbesondere für die Oberwagen von Kranfahrzeugen, wobei die Tragrollen auf einem Laufkranz abrollen.The invention relates to support rollers for turntables, in particular for the superstructure of crane vehicles, with the support rollers rolling on a running ring.

Der grundsätzliche Erfindungsgedanke geht dahin, daß die Rollen eines Drehkranzesy z. B. für Kranfahrzeuge, um eine außerhalb der äußeren Rollenstirnfläche befindliche, winkelig zur Rollenachse angeordnete Achse schwenkbar sind, wodurch ein Ausschwenken der Rollen aus dem Laufkranz heraus und damit ein Abheben des Oberwagens mit den an diesem angebrachten Rollen ermöglicht wird. Zu diesem Zweck mögen die Tragrollen auf winkelförmigen Haltern gelagert sein, die z. B. am Oberwagen drehbar angebracht sind. In der Betriebsstellung werden die Winkelhalter durch Riegel gesichert. Die Tragrollen können höhenverstellbar angeordnet und so gelagert sein, daß einige von ihnen außen an den Flanken des Radkranzes laufen.The basic idea of the invention is that the roles of a Slewing ring z. B. for crane vehicles to an outside of the outer roller face located, at an angle to the roller axis arranged axis are pivotable, whereby a pivoting of the rollers out of the running ring and thus a lifting of the superstructure is made possible with the rollers attached to it. For this purpose they like Support rollers be mounted on angular holders that z. B. rotatable on the superstructure are attached. In the operating position, the angle brackets are secured with bolts. The support rollers can be arranged adjustable in height and mounted so that some run from them outside on the flanks of the wheel rim.

In der Zeichnung ist der Gegenstand der Erfindung ih einer Settenansdcht im Schaistt (Abt.. i) und in einer Draufsicht dazu (Abt. 2) dargestellt.In the drawing, the subject of the invention is a Settenansdcht in the Schaistt (Dept. i) and in a plan view (Dept. 2).

Um eine gleichmäßig gute Führung des Oberwagens bei jeder Neigung im Gelände und auch bei jeder wechselnden Belastung zu erzielen, werden die Laufrollen d in einem U-förmig ausgebildeten Drehkranz geführt. Zur leichteren Montage und Demontage des Oberwagens gegenüber dem Unterwagen werden diese Rollen frei hängend auf winkelförmig ausgebildeten Haltern, c angeordnet, so daß sie zunächst beim Aufsetzen während der Montage die Stellung d1 annehmen, um dann in die gezeichnete Stellung d eingeschwenkt zu werden. -Das Festhalten in der Betriebsstellung erfolgt durch Riegel e. Einige Tragrollen d können auch zur Erzielung einer spielfreien Führung des Oberwaigens außen an den Flanken des Rades a, d. h. also nicht im Profil, laufen und. zu diesem Zweck höhenverstellbar sein, so daß man die Rollen, die dafür in Betracht kommen sollen, auswählen kann.A consistently good guidance of the superstructure on every slope In the field and also with every changing load, the rollers d guided in a U-shaped turntable. For easier assembly and Disassembly of the superstructure compared to the undercarriage, these roles are freely hanging arranged on angled holders, c, so that they are initially placed upon placement Assume position d1 during assembly and then move to the position shown d to be swiveled in. -The holding in the operating position is carried out by Latch e. Some idlers can also be used to achieve a backlash-free guide of the upper weight outside on the flanks of the wheel a, d. H. so not in profile, run and. for this purpose it should be adjustable in height so that the rollers that are used in Should be considered, can choose.
