Description

Die Erfindung betrifft eine teleskopierbare Turmwagenar­ beitsbühne.The invention relates to a telescopic tower car working stage.

Die bekannten Turmwagenarbeitsbühnen dieser Art haben den Nachteil, daß durch die konstruktive Gestaltung der Hub-, Schwenk- und Bühnendreheinrichtung ein begrenzter Ak­ tionsradius vorgegeben ist, der nicht umfassend alle zur Fahrleitungsanlage gehörenden Bauelemente positionsmäßig erfassen kann.The well-known tower car working platforms of this type have the Disadvantage that the design of the lifting, Swivel and stage rotation device a limited Ak radius is specified, which does not include all of the Components belonging to the catenary system in terms of position can capture.

Aus diesem Grund war es notwendig, weitere Arbeitsmittel, Montageleitern oder Hubsteiger, einzusetzen.For this reason, it was necessary to add more tools, Installation ladders or lifting platforms.

Der Erfindung liegt die Aufgabe zugrunde, daß durch eine hydraulische Teleskopiereinrichtung eine Verlängerung des Tragarmes erreicht wird, um dadurch den Arbeitsbereich so zu vergrößern, daß sich der Einsatz eines weiteren Ar­ beitsmittels erübrigt.The invention has for its object that by a hydraulic telescopic device an extension of the Support arm is reached, thereby the work area so to enlarge that the use of another Ar means no longer necessary.

Die Vergrößerung des Arbeitsbereiches der Montagebühne wird dadurch erreicht, daß der aus zwei ineinanderge­ stellten Bauteilen bestehende Tragarm über einen doppelt wirkenden Hydraulikzylinder längenveränderlich gestaltet wird.The enlargement of the working area of the assembly platform is achieved in that the two of each other provided existing support arm components over a double acting hydraulic cylinder variable in length becomes.

Bevorzugtes Einsatzgebiet der Erfindung sind Montage, Demontage und Revisionsarbeiten an Oberleitungen der elektrisch betriebenen Triebfahrzeuge und Signaleinrich­ tungen.Preferred areas of application of the invention are assembly, Disassembly and revision work on overhead lines of the electrically powered traction vehicles and signaling equipment exercises.

Weitere Einzelheiten der teleskopierbaren Turmwagenar­ beitsbühne ergeben sich aus der Zeichnung, in welcher bevorzugte Ausführungsformen dargestellt sind. Further details of the telescopic tower car beitsbühne result from the drawing in which preferred embodiments are shown.

Die Erfindung ist dadurch gekennzeichnet, daß der Tragarm zwischen der drehbaren Nackenstütze und der Tragkonstruk­ tion der Arbeitsbühne längenveränderlich gestaltet ist. Der konstruktiv doppelt gestaltete Tragarm ist durch die Längenveränderung des doppelt wirkenden Arbeitszylinders veränderlich gestaltet.The invention is characterized in that the support arm between the rotating neck support and the supporting structure tion of the work platform is variable in length. The structurally double support arm is due to the Length change of the double-acting working cylinder variably designed.

Der Wirkungsbereich der Arbeitsbühne verändert sich durch die konstruktiv doppelte Gestaltung des Tragarmes.The scope of the work platform changes through the constructive double design of the support arm.

Das wird erreicht durch Ein- oder Ausfahren des doppelt wirkenden Arbeitszylinders.This is achieved by retracting or extending the double working cylinder.
