Description

Es ist häufig erforderlich, einem drefoaren Teil Strom zuzuführen·, wie z. B. dem Hubwerksmotor einer Drehlaufkatze. Die Stromüberleitung vom feststehenden zum drehbaren Teil erfolgt im allgemeinen durch Schleifringe. Sind die Drehbewegungen begrenzt, dann kann man auf diese Art der Stromüberleitung verzichten und mit einem zwischen den gegeneinander verdrehbaren Teilen lose ■ aufgehängten Kabeln auskommen. Man läßt in ίο diesem Falle einen Teil des Kabels aus Schlaufe nach unten hängen, die um so langer sein muß, je größer der Drehbereich des beweglichen Teiles ist. Dieses frei hängende Kabel· stört aber in vielen Fällen die Drehbewegungen· und kann außerdem leicht beschädigt werden.It is often necessary to have a three-dimensional part To supply electricity, such as B. the hoist motor of a rotating trolley. The current transfer from fixed to rotatable part generally takes place through slip rings. If the rotational movements are limited, then you can use this type of Do without current transfer and loose with one between the mutually rotatable parts ■ suspended cables manage. In this case, part of the cable is left out of a loop hang down, which must be longer, the greater the range of rotation of the moving part. This freely hanging cable, however, in many cases interferes with the rotary movements and can also easily damaged.

Die Erfindung, welche diesen Mängeln abhilft, betrifft eine Einrichtung für.die Stromüberleitung auf einen von zwei um die gleiche senkrechte Achse gegeneinander begrenzt verdrehbaren Teilen mittels ao eines zwischen diesenTeilen vorgesehenen, auf- und abwickelbaren, elektrischen Kabels, insbesondere für Hebezeuge mit einem feststehenden und einem gegenüber diesem um eine senkrechte Achse drehbaren Teil. Bei-einer derartigen Einrichtung wird gemäß der Erfindung vorgeschlagen, einen topfartigen, konzentrisch zur Drehachse der Teile angeordneten Behälter vorzusehen, in welchem das von oben dem Behälter zugeführte und auf dem Behälterboden aufliegende Verbindungskabeli derartig spiralförmig aufgewickelt ist, daß sich je nach der Drehrichtung des drehbaren Teiles die Kabelspirale aufdreht oder zuzieht.The invention, which remedies these deficiencies, relates to a device für.die Stromüberleitung on one of two mutually limited rotatable parts about the same vertical axis by means of ao of an electrical cable which is provided between these parts and can be wound up and unwound, in particular for hoists with one stationary and one that can be rotated around a vertical axis Part. In such a device is proposed according to the invention, a pot-like, to provide a container arranged concentrically to the axis of rotation of the parts, in which the at the top of the container and on the container bottom overlying connecting cables in such a spiral shape is wound that, depending on the direction of rotation of the rotatable part, the spiral cable untwists or closes.

Befestigt man den Behälter am drehbaren Teil,If you attach the container to the rotating part,

dann wird das von oben her zugeführte Kabel mit dem feststehenden Teil verbunden. Bei Anordnung des Behälters am feststehenden Teil führt dieses Kabelende hingegen, zum drehbaren, Teil.then the cable fed in from above is connected to the fixed part. When ordered of the container on the stationary part, however, this cable end leads to the rotatable part.

In der Zeichnung ist in den Abb. 1 und 2 eine Ausführungsform der Erfindungsgegenstandes im Seitenschnitt und in der Draufsicht dargestellt.In the drawing, in Figs. 1 and 2, an embodiment of the subject matter of the invention is in Side section and shown in plan view.

Es sei angenommen, daß der Behälter ϊ am drehbaren Teil befestigt ist, z. B-. auf dem Drehgestell einer Drehlaufkatze. Das von oben her zugeführte Kabel 2 kommt dann vom feststehenden Teil, bildet im Inneren des Behälters eine Spirale 3 und verläßt diesen durch den in der Behälterwand angeordneten Stutzen 4. Wird der Behälter in Pfeilrichtung A verdreht, dann dreht sich die Spirale auf, bei Verdrehung in Pfeilrichtung B hingegen zieht sie sich zusammen.It is assumed that the container ϊ is attached to the rotatable part, e.g. B-. on the bogie of a rotating trolley. The from above supplied cable 2 then comes from the fixed part, forms inside the tank a spiral 3 and leaves this through the arranged in the container wall neck 4. When the container in the direction of arrow A twisted to the spiral turns on, upon rotation in the direction of arrow B, however, it contracts.

Bildet man den Behälter eben aus, dann kann der Fall eintreten, daß die Kabelwindungen sich nicht in Spiralform anordnen, sondern sich zum Teil überlagern. Es treten dann zusätzliche Reibungen und Biegungsbeanspruchungen auf, die den Ver-Schleiß des Kabels begünstigen.If the container is made flat, the situation may arise in which the cable windings do not move arrange in a spiral shape, but partially overlap. Additional friction then occurs and bending stresses that promote wear and tear on the cable.

Die Erfindung schlägt deshalb weiter vor, den Behälterboden so auszubilden, daß er einen nach unten offenen Kegel darstellt. Bei dieser Ausbildung des Bodens ist das Kabel infolge seines Eigengewichtes bestrebt, nach außen zu wandern und bildet daher in jedem Falle eine Spirale. Diese Wirkung wird unterstützt, wenn man die Bodenfläche poliert.The invention therefore further proposes to design the container bottom so that it is one after represents open cone at the bottom. With this design of the floor, the cable is due to its own weight endeavors to migrate outwards and therefore forms a spiral in each case. These Effect is supported if you polish the floor surface.
