Abstract

The object of the invention is to achieve an extension of the supporting arm by a hydraulic telescopic device in order to thereby increase the working range to such an extent that the use of a further operating agent is unnecessary. The increase in the working range of the erecting platform is achieved owing to the fact that the supporting arm consisting of two components placed one inside the other is designed so as to be variable in length via a double-acting hydraulic cylinder. <IMAGE>

Description

Die Erfindung betrifft eine teleskopierbare Turmwagenarbeitsbühne.The invention relates to a telescopic tower car working platform.

Die bekannten Turmwagenarbeitsbühnen dieser Art haben den Nachteil, daß durch die konstruktive Gestaltung der Hub-, Schwenk- und Bühnendreheinrichtung ein begrenzter Aktionsradius vorgegeben ist, der nicht umfaßend alle zur Fahrleitungsanlage gehörenden Bauelemente positionsmäßig erfassen kann.The known tower car working platforms of this type have the disadvantage that the constructional design of the lifting, swiveling and rotating platform means that there is a limited range of action which cannot comprehensively detect all the components belonging to the overhead contact line system.

Aus diesem Grund war es notwendig, weitere Arbeitsmittel, Montageleitern oder Hubsteiger, einzusetzen.For this reason, it was necessary to use additional work equipment, assembly managers or elevators.

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 Arbeitsmittels erübrigt.The invention has for its object that an extension of the support arm is achieved by a hydraulic telescopic device, thereby enlarging the working area so that the use of another tool is unnecessary.

Die Vergrößerung des Arbeitsbereiches der Montagebühne wird dadurch erreicht, daß der aus zwei ineinandergestellten 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 support arm, which consists of two nested components, is designed to be variable in length via a double-acting hydraulic cylinder.

Bevorzugtes Einsatzgebiet der Erfindung sind Montage, Demontage und Revisionsarbeiten an Oberleitungen der elektrisch betriebenen Triebfahrzeuge und Signaleinrichtungen.The preferred area of application of the invention is assembly, disassembly and revision work on overhead lines of the electrically operated traction vehicles and signaling devices.

Weitere Einzelheiten der teleskopierbaren Turmwagenarbeitsbühne ergeben sich aus der Zeichnung, in welcher bevorzugte Ausführungsformen dargestellt sind.Further details of the telescopic tower car working platform can be seen in the drawing, in which preferred embodiments are shown.

Die Erfindung ist dadurch gekennzeichnet, daß der Tragarm zwischen der drehbaren Nackenstütze und der Tragkonstruktion der Arbeitsbühne längenveränderlich gestaltet ist. Der konstruktiv doppelt gestaltete Tragarm ist durch die Längenveränderung des doppelt wirkenden Arbeitszylinders veränderlich gestaltet.Figure 1

The invention is characterized in that the support arm between the rotatable neck support and the support structure of the work platform is designed to vary in length. The support arm, which has a double design, can be modified by changing the length of the double-acting working cylinder.

Der Wirkungsbereich der Arbeitsbühne verändert sich durch die konstruktiv doppelte Gestaltung des Tragarmes.The effective range of the work platform changes due to the double construction of the support arm.

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