Description

Stromabnehmer. Bekanntlich besteht der Stromabnehmer zum Abnehmen des Stromes für Krane o. dgl. von der Schleifleitung aus einem diese Leitung umgreifenden, leicht drehbar an einen Bolzen angehängten Bügel. Da nun bisher der Strom bei derartigen Stromabnehmern unmittelbar von dem Bügel zum Aufhängeholzen gelangen konnte, so waren gewöhnlich schon nach kurzer Zeit die Bolzen und die Augen des Stromabnehmers, durch welche der Bolzen geführt wurde, angeschmort. Hierdurch wurde nun der Kontakt zwischen Schleifschuh und Kontaktträger, besonders jedoch durch den beim Schmoren sich bildenden Zunder, immer schlechter. Dieser Übelstand war insbesondere in Gießereien und ähnlichen schmutzigen Betrieben sehr häufig zu beobachten. Bekannt sind bereits Stromabnehmer, bei welchen die Funkenbildung zwischen Bolzen und Bügel durch besondere federnde Parallelverbindung vermieden werden soll, was aber infolge der nicht festen Kontakte nicht ganz erreicht wird. Anders bei dem Gegenstand der Erfindung, bei welchem die unmittelbare Berührung zwischen Bügel und Bolzen durch eine Isolationsbüchse verhindert wird und die Verbindung zwischen den beiden durch ein fest mit ihnen verbundenes Kabel hergestellt wird. Eine Funkenbildung ist demnach ausgeschlossen. In der Zeichnung ist eine Ausführungsform des Erfindungsgedankens beispielsweise dargestellt, und zwar zeigt Abb. i den Stromabnehmer in Seitenansicht, Abb. a einen Vertikalschnitt durch denselben gemäß Schnittlinie A-B nach Abb. i. Der aus Messing bestehende Kontaktträger 'i dient zur Befestigung des Stromabnehmers. Der Stromabnehmer selbst besteht weiter - aus Isolierbüchsen q., die aus einem dazu geeigneten Material, wie Hartgummi, Ebonit usw., bestehen, dem Messingschleifschuh 5, der Messingstellmutter a und den eisernen Unterlegscheiben 3 und 6, den beiden Messingklemmschrauben 7 und 9, dein Verhindungskabel 8 aus bekanntem Leitungsmaterial. Die Stromzufuhr erfolgt also durch das Verbindungskabel zwischen Schleifschub und Kontaktträger.Pantograph. As is well known, there is a pantograph to be removed the current for cranes or the like from the conductor line from a surrounding this line, Easily rotatable bracket attached to a bolt. Since now the current with such Pantographs could get directly from the bracket to the suspension bolt, so the bolts and the eyes of the pantograph were usually after a short time, through which the bolt was passed, scorched. This made contact between the sanding shoe and the contact carrier, but especially due to the braising scale that forms, getting worse and worse. This drawback was particularly common in foundries and similar filthy operations to be observed very often. Are already known Current collectors, in which the spark formation between the bolt and bracket by special resilient parallel connection should be avoided, but this is due to the not fixed Contacts is not quite reached. Different with the subject matter of the invention which is the direct contact between bracket and bolt through an insulation sleeve is prevented and the connection between the two by a firm with them connected cable is established. Spark formation is therefore excluded. In the drawing, an embodiment of the inventive concept is for example shown, namely Fig. i shows the pantograph in side view, Fig. a a Vertical section through the same according to section line A-B according to Fig. I. The one made of brass existing contact carrier 'i is used to attach the pantograph. The pantograph itself further consists of - insulating sleeves q., which are made of a suitable material, such as hard rubber, ebonite, etc., exist, the brass shoe 5, the brass adjusting nut a and the iron washers 3 and 6, the two brass clamping screws 7 and 9, your connecting cable 8 made of known line material. The power is supplied that is, through the connecting cable between the sliding thrust and the contact carrier.
