Description

Beim Entladen von Schiffen und beim vollständigen Räumen umgrenzter Lagerplätze mittels Selbstgreifer ist es notwendig, den Greifer an den Rändern und besonders an den Ecken der Lagerräume in verschiedene Stellungen zu bringen, um das Gut möglichst restlos aufnehmen zu können. Man muß den Greifer zu diesem Zwecke um seine Achse drehen, wozu zwei Bedienungsleute erforderlich sind. Die Erfindung bezieht sich auf eine mechanische Einrichtung, welche diese Bedienungsleute überflüssig machen soll, indem sie gestattet, den Greifer um seine Achse zu schwenken. Die Lösung dieser Aufgabe erfolgt nach der Erfindung im wesentlichen dadurch, daß die Leitrollen, über die die Aufhängeseile des Selbstgreifers geführt sind, derart getrennt voneinander angeordnet werden, daß ihre gegenseitige Lage verändert werden kann. Die Verschiebungsvorrichtung für die Leitrollen besteht nach der Erfindung z. B. darin, daß jede Leitrolle an einer Mutter befestigt ist, die auf einer Spindel verschoben. werden kann; die Spindel liegt dabei in der Richtung der Greiferseile zur Winde. Durch gegenseitige Verschiebung der Leitrollen tritt daher keine seitliche Ablenkung der Seile auf. Wichtig ist nach der Erfindung auch noch die abgefederte, achsial verschiebbare Lagerung der Spindeln, da dadurch die beim Greiferbetrieb unvermeidlichen Stöße, die in den Leitrollen auftreten, unschädlich gemacht werden können.When unloading ships and when completely clearing out delimited storage areas using self-grippers, it is necessary to use the gripper at the edges and especially at the To bring corners of the storage rooms in different positions in order to keep the goods as completely as possible to be able to record. For this purpose, the gripper has to be around its axis turning, which requires two operators. The invention relates to a mechanical device which is intended to make these operators superfluous by allows the gripper to pivot about its axis. This task is solved according to the invention essentially in that the guide rollers over which the suspension ropes the self-gripper are guided, are arranged separately from each other that their mutual position changed can be. The displacement device for the guide rollers consists according to the invention z. B. is that each idler pulley is attached to a nut that is moved on a spindle. can be; the spindle is in the direction of the gripper ropes to the winch. By mutual displacement of the guide rollers therefore does not cause any lateral deflection of the ropes. According to the invention, the spring-loaded, axially displaceable mounting is also important of the spindles, as this results in the unavoidable shocks in the gripper operation Guide rollers occur, can be rendered harmless.

Auf der Zeichnung ist eine Ausführungsform der Erfindung in Fig. ι im Aufriß sehematisch dargestellt. Die Fig. 2 und 3 zeigen zwei Grundrisse zu Fig. 1 mit verschiedener Stellung der Leitrollen bzw. des Greifers.In the drawing, an embodiment of the invention in Fig. Ι is shown in elevation shown. FIGS. 2 and 3 show two floor plans for FIG. 1 with different ones Position of the guide rollers or the gripper.

Der Greifer 1 ist in der üblichen Weise mit zwei Seilpaaren 2 und 3 aufgehängt und wird mittels der Windentrommeln 4 und 5 bewegt. Die Seilpaare sind über zwei Leitrollenpaare 6 bzw. 7 geführt, welche mit ihrem als Mutter ausgebildeten Gehäuse 8 auf den Spindeln 9 sitzen. Diese Spindeln können durch das Getriebe 10 in entgegengesetztem Sinne gedreht werden, wodurch eine Verschiebung der Leitrollengehäuse in der Weise eintritt, wie sie in Fig. 3 dargestellt ist, so daß der Greifer, wie diese Figur ebenfalls zeigt, um seine Achse geschwenkt wird. Die Spindeln 9 sind in ihrer Längsrichtung verschiebbar gelagert und mit Pufferfedern 11 versehen, welche die in den Leitrollen auftretenden Stöße aufnehmen und unschädlich machen.The gripper 1 is suspended in the usual way with two pairs of cables 2 and 3 and is moved by means of the winch drums 4 and 5. The pairs of ropes are over two pairs of idler pulleys 6 and 7 out, which with their housing designed as a nut 8 on the spindles 9 sit. These spindles can be rotated in opposite directions by the transmission 10 be, whereby a displacement of the guide pulley housing occurs in the manner as it is shown in Fig. 3, so that the gripper, as this figure also shows, to his Axis is swiveled. The spindles 9 are mounted displaceably in their longitudinal direction and provided with buffer springs 11, which absorb the impacts occurring in the guide rollers and render it harmless.
