Description
Die Erfindung betrifft eine mobile Arbeitsbühne mit fle xibler Arbeitsstellung.The invention relates to a mobile work platform with fle xibler working position.
Die bekannten mobilen Arbeitsbühnen arbeiten zum einen nach dem Prinzip der Scherenhebebühne und zum anderen nach dem Autodrehkrankonstruktionsprinzip. Alle bekannten mobi len Arbeitsbühnen haben den Nachteil, daß sie sich jeweils nur um einen Punkt drehen. Dadurch ergibt sich, daß bei ausgeschwenkter Arbeitsbühne bei seitlichen Arbeiten nur die Stirnseiten der Bühne als Arbeitsbreite zur Verfügung stehen (vgl. DE-PS 39 13 645 C1, DE OS 24 18 158).The well-known mobile working platforms work on the one hand according to the principle of the scissor lift and the other the principle of the car turning crane construction. All known mobi len work platforms have the disadvantage that they are each just rotate one point. This means that at swung out work platform for side work only the front sides of the stage are available as working width stand (cf. DE-PS 39 13 645 C1, DE OS 24 18 158).
Aufgabe der Erfindung ist es, eine Arbeitsbühne in der Gesamtheit mit zwei Drehpunkte auszugestalten. Dadurch besteht die Möglichkeit, über das Grundprinzip des Auto drehkranes den Drehpunkt 1 zu nutzen. Eine Kugeldrehver bindung zwischen der Lastarmkonstruktion und der Bühne gestattet es, bei ausgeschwenktem Lastarm ein Drehen der Bühne zu ermöglichen. Dadurch ist die Voraussetzung gege ben, daß in jeder Arbeitsstellung die gesamte Bühnenfläche genutzt werden kann. Sowohl der Hub- als auch der Schwenk vorgang des Drehpunktes 1 und der Drehvorgang des Dreh punktes 2 werden durch den Einsatz der bordeigenen Hydrau lik betrieben. Die Steuerung der Arbeitsvorgänge erfolgt über Elektromagnetventile und ist sowohl von der Arbeits bühne aus in jeder Arbeitsstellung möglich als auch im Notfall vom Bodenpersonal durchzuführen.The object of the invention is to design a work platform in its entirety with two pivot points. This makes it possible to use pivot point 1 via the basic principle of the slewing crane. A spherical swivel connection between the load arm construction and the platform allows the platform to be rotated when the load arm is pivoted out. This ensures that the entire stage area can be used in every working position. Both the lifting and the pivoting process of the pivot point 1 and the turning process of the pivot point 2 are operated lik by the use of the on-board hydraulic. The work processes are controlled by solenoid valves and can be carried out in any working position from the work platform or carried out by the ground staff in an emergency.
Bevorzugtes Einsatzgebiet der Erfindung sind Montage-, De montage- und Revisionsarbeiten an Oberleitungen für elek trisch betriebene Triebfahrzeuge.Preferred areas of application of the invention are assembly, De assembly and revision work on overhead lines for elec powered locomotives.
Weitere Einzelheiten der mobilen Arbeitsbühne mit flexib ler Arbeitsstellung sind aus der Zeichnung zu ersehen.Further details of the mobile working platform with flexibility The working position can be seen from the drawing.

Pos. 1 The view shows the ball slewing ring with hydrostatic drive installed between the platform and the boom construction,
Pos. 2 view of the glass fiber reinforced plastic platform as work platform,
Pos. 3 stabilizing arm to ensure parallel guidance between the vehicle base frame of the work platform,
Pos. 4 load arm for lifting the working platform,
Pos. 5 View of the rotatable neck support as the basic construction of the slewing crane.
Aus der Ansicht der Fig. 1 ist die Anordnung der zwei Drehpunkte der mobilen Arbeitsbühne zu ersehen und die daraus mögliche flexible Stel lung der Bühne zu erkennen.From the view of Fig. 1, the arrangement of the two pivots of the mobile work platform can be seen and the possible flexible Stel development of the stage can be seen.
Die Erfindung ist dadurch gekennzeichnet, daß die drehbare Nackenstütze und die zwischen der Tragkonstruktion und der Arbeitsbühne angebrachte Kugeldrehverbindung als zwei Drehpunkte im Gesamtsystem die Flexibilität der Arbeits bühne ermöglichen. Durch die flexible Arbeitsstellung ist es möglich, die Bühnenarbeitsstellung jeweils so zu wäh len, daß ständig die optimale Arbeitsfläche am Montageort genutzt wird.The invention is characterized in that the rotatable Neck support and that between the supporting structure and the Work platform mounted ball slewing ring as two Pivots in the overall system the flexibility of work enable stage. Because of the flexible working position it is possible to choose the stage work position in this way len that the optimal work surface at the installation site is being used.
