Der auf der beiliegenden Zeichnung dargestellte Gegenstand vorliegender Erfindung betrifft eine Aufzugswinde für elektrische Beleuchtungskörper, insbesondere für Bogenlampen, mit vereinigtem Trag- und Leitungskabel. Zweck und Einrichtung sind nachstehend beschrieben.The subject matter of the present invention shown in the accompanying drawings relates to an elevator winch for electrical lighting fixtures, in particular for arc lamps, with combined suspension and line cable. The purpose and setup are described below.
An der Trommel α (Fig. i) ist in üblicher Weise das Aufzugsseil b befestigt, dessen ίο Zusammensetzung aus der Fig. 2 ersichtlich ist. Drahtseil c und die Stromleitungen d und e sind in bekannter Weise in einem gemeinsamen Kabel vereinigt. The elevator rope b , the composition of which can be seen in FIG. 2, is attached to the drum α (FIG. I) in the usual manner. Wire rope c and power lines d and e are combined in a known manner in a common cable.
Auf der Trommel α sitzt isoliert gebettet der feste Kontaktunterteil/ mit den Kontaktstücken g und h, die in bekannter Weise mit den Enden d und e des Kabels (Fig. 2) verbunden sind.The fixed lower contact part / with the contact pieces g and h, which are connected in a known manner to the ends d and e of the cable (FIG. 2), sits in an insulated bed on the drum α.
Der bewegliche Kontaktoberteil i mit den Kontaktstücken k und m ist durch ein Kabel η mit der Speiseleitung verbunden.The movable upper contact part i with the contact pieces k and m is connected to the feed line by a cable η.
Wie die Fig. 1 zeigt, kann die Kurbel 0As FIG. 1 shows, the crank 0
der Winde nicht gedreht werden, solange die Kontaktteile / und i miteinander verbunden sind; soll die Lampe aufgezogen oder heruntergelassen werden, so muß der bewegliche Kontaktoberteil abgehoben werden. Infolgedessen ist die Lampe sowohl beim Aufwinden als auch beim Niederlassen stets stromlos. Winde und Gehäuse sind immer stromlos.the winch cannot be rotated as long as the contact parts / and i are connected to one another; if the lamp is to be raised or lowered, the movable upper contact part must be lifted off. As a result, the lamp is always de-energized both when it is winded up and when it is lowered. The winch and housing are always de-energized.
Wird die Winde im Freien angeordnet, so schützt eine in der Zeichnung nicht dargestellte Klappe mit verschließbarer Öffnung die Kontaktkupplung und das Kabel η gegen Witterungseinflüsse und böswillige Störungen.If the winch is arranged outdoors, a flap (not shown in the drawing) with a closable opening protects the contact coupling and the cable η against the effects of the weather and malicious interference.
