Description

Die Erfindung betrifft ein schienenverfahrbares Arbeitsgerät entsprechend dem Oberbegriff des Hauptanspruches.The invention relates to a rail-traveling implement according to the preamble of the main claim.

Eine Vorrichtung dieser Art ist aus dem DE-U-7640229 bekannt. Dieses bekannte Arbeitsgerät schafft für den Benutzer die Möglichkeit, aufgrund des schwenkbaren und hebbaren Auslegers eine Vielzahl von Arbeitsvorgängen ausführen zu können. Darüber hinaus gibt es gewisse Arbeiten, die nur unter Zuhilfenahme mehrerer Personen durchgeführt werden können, so daß zusätzlich ein anderes bekanntes Arbeitsgerät erforderlich war (z. B. entsprechend der FR-PS 2224400), das an seiner Oberseite eine hebbare Arbeitsbühne trägt, die von mehreren Personen betreten werden kann, so daß diese Personen dann die jeweils anfallenden Arbeiten, wie beispielsweise das Aufhängen von Fahrdraht an den den Fahrdraht haltenden hakenartigen Elementen oder die Reparatur an Fahrdrähten vornehmen können.A device of this type is known from DE-U-7640229. This known implement creates the possibility for the user to be able to carry out a large number of work processes due to the pivotable and liftable boom. In addition, there are certain works that can only be carried out with the help of several people, so that another known work tool was required (e.g. according to FR-PS 2224400), which carries on its top a lifting platform, which by Several people can be entered, so that these people can then carry out the respective work, such as hanging up the contact wire on the hook-like elements holding the contact wire or repairing the contact wire.

Da der schwenkbare Arbeitsstand bei der bekannten Einrichtung gemäß dem DE-U-7 640 229 über den gesamten Dachbereich verschwenkbar sein muß, besteht bei dieser Vorrichtung keine Möglichkeit, eine solche Arbeitsbühne gemäß der FR-PS 2 224 400 zusätzlich anzuordnen, ohne daß durch diese zusätzliche Arbeitsbühne der Einsatzbereich des schwenkbaren Auslegers und des daran angeschlossenen Arbeitsstandes eingeschränkt würde.Since the swiveling work stand in the known device according to DE-U-7 640 229 must be pivotable over the entire roof area, there is no possibility with this device to additionally arrange such a work platform according to FR-PS 2 224 400 without this additional working platform would limit the area of application of the swiveling boom and the work stand connected to it.

Der Erfindung liegt die Aufgabe zugrunde, ein schienenverfahrbares Arbeitsgerät mit von einem Ausleger getragenem Arbeitsstand zu schaffen, bei welchem trotz vollständiger Einsatzmöglichkeit des schwenkbaren Auslegers mit Arbeitsstand eine zusätzliche Arbeitsbühne gleichzeitig mit vorgesehen ist, die in der eingefahrenen und ausgefahrenen Lage benutzbar ist und sich innerhalb des Fahrzeugbegrenzungsprofils befindet und die Bewegungsmöglichkeit des ausschwenkbaren Arbeitsstandes nicht beeinträchtigt.The invention has for its object to provide a rail-driven working device with a work stand carried by a cantilever, in which, despite the full use of the swiveling cantilever with work stand, an additional work platform is also provided, which can be used in the retracted and extended position and can be used within the Vehicle limitation profile is located and does not impair the possibility of movement of the swing-out work station.

Diese der Erfindung zugrundeliegende Aufgabe wird dadurch gelöst, daß auf dem Dach des Arbeitsgerätes ein Rahmengestell angeordnet ist und seitlich der mittleren Längsachse des Arbeitsgerätes im Bereich des abgesenkten Auslegers zwei Bühnenplattformen vorgesehen sind, die zwischen einer tieferen Ruhe- oder Arbeitsstellung und einer höheren Arbeitsstellung, in der sie gemeinsam eine Arbeitsfläche bilden, durch durch hydraulische oder pneumatische Kolbenzylinderanordnungen betätigte Lenker schwenkbar sind.This object of the invention is achieved in that a frame is arranged on the roof of the implement and two platform platforms are provided on the side of the central longitudinal axis of the implement in the area of the lowered boom, which between a lower rest or work position and a higher work position, in which together they form a work surface, can be pivoted by handlebars actuated by hydraulic or pneumatic piston-cylinder arrangements.

Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Further advantageous refinements are described in the subclaims.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is explained below with reference to an embodiment shown in the drawing.

Es zeigt

  • Fig. 1 ein schienenverfahrbares Arbeitsgerät in schematischer Seitenansicht,
  • Fig. 2 eine Arbeitsbühne auf dem Arbeitsgerät in schaubildlicher Darstellungsweise und in vergrößerter Darstellung,
  • Fig.3 eine Draufsicht auf die Einrichtung gemäß Fig. 2 und
  • Fig.4 eine Frontansicht auf einen Teil eines Arbeitsgerätes, das mit der Arbeitsbühne ausgerüstet ist.
It shows
  • 1 is a rail-driven working device in a schematic side view,
  • 2 is a working platform on the implement in a diagrammatic representation and in an enlarged representation,
  • 3 shows a plan view of the device according to FIG. 2 and
  • 4 shows a front view of a part of an implement that is equipped with the work platform.

Ein schienenverfahrbares Arbeitsgerät 1 in Form eines Fahrzeuges trägt einen Radsätze 2 aufweisenden Rahmen 3, der in seiner Mitte einen Drehschemel 4 (gestrichelt dargestellt) mit einem Ausleger 5 aufweist, der an seinem Ende in an sich bekannter Weise mit einem Arbeitsstand 6 versehen ist. Der Ausleger 5 liegt im vorderen Teil des Daches des eigentlichen Arbeitsgerätes 1, in dessen Bereich eine Arbeitsbühne 7 vorgesehen ist.A rail-driven implement 1 in the form of a vehicle carries a frame 3 having wheel sets 2, which has in its center a turntable 4 (shown in dashed lines) with a boom 5, which is provided at its end with a work station 6 in a manner known per se. The boom 5 is located in the front part of the roof of the actual implement 1, in the area of which a work platform 7 is provided.

In dem vom Ausleger in der Ruhelage und von der Arbeitsbühne 7 freien Teil des Daches des Arbeitsfahrzeuges 1 ist ein Meßbügel 8 vorgesehen, der in die in Fig. 1 dargestellte Ruhelage und in eine nicht dargestellte Arbeitslage klappbar ist, wobei die Bewegungen des Meßbügels über eine Fernsehkamera 9 kontrollierbar sind, die ihre Werte in das Innere des Arbeitsfahrzeuges 1 abgibt, wo nunmehr entsprechende Kontroll- und Aufzeichnungsgeräte vorgesehen werden können. Die Fernsehkamera ist ebenfalls in vollen Linien in der Ruhelage und gestrichelt in einer Arbeitslage dargestellt.In the part of the roof of the work vehicle 1 which is free from the boom in the rest position and from the work platform 7, a measuring bracket 8 is provided which can be folded into the rest position shown in FIG. 1 and into a working position (not shown), the movements of the measuring bracket via a TV camera 9 are controllable, which outputs their values into the interior of the work vehicle 1, where appropriate control and recording devices can now be provided. The television camera is also shown in full lines in the rest position and in dashed lines in a working position.

Die Arbeitsbühne 7 enthält ein Rahmenteil 10, das aus einem umlaufenden, beispielsweise der Form des Daches angepaßten Rechteck besteht, das sich über Stützplatten 11 auf der Dachoberseite so großflächig abstützen kann, daß eine ausreichende Tragfähigkeit erreicht wird. Innerhalb dieses Rahmenteiles 10 und schwenkbar mit entsprechenden Tragelementen mit diesem Rahmenteil verbunden sind Lenker 12 vorgesehen. Die Arbeitsbühne 7 besteht aus zwei anhebbaren Bühnenplattformen 16 und 20, die mit Hilfe der genannten Lenker 12 und weiterer Lenker 14 und 17 anhebbar sind, wobei die Lenker 14 und 17 am Rahmenteil durch ein Gelenk 15 bzw. 18 angelenkt sind. Ein Gelenk 19 verbindet den zweiten Lenker 17 mit der Bühnenplattform 16.The work platform 7 contains a frame part 10, which consists of a circumferential rectangle, for example adapted to the shape of the roof, which can be supported over support plates 11 on the top of the roof so that a sufficient load-bearing capacity is achieved. Handlebars 12 are provided within this frame part 10 and pivotably connected to this frame part with corresponding support elements. The work platform 7 consists of two liftable platform platforms 16 and 20, which can be raised with the help of the mentioned link 12 and further link 14 and 17, the link 14 and 17 being articulated on the frame part by a joint 15 and 18, respectively. A hinge 19 connects the second link 17 to the stage platform 16.

Durch eine entsprechende Bewegung der beiden Lenker 14 und 17 um die Gelenke 15 bzw. 18 kann nunmehr ein Hochschwenken der Bühnenplattform 16 erfolgen, so daß dadurch ein Führen der Bühnenplattform in die F i g. 1 dargestellte Arbeitslage möglich ist.The stage platform 16 can now be swiveled up by a corresponding movement of the two links 14 and 17 about the joints 15 and 18, respectively, so that the stage platform is guided into the FIG. 1 work situation shown is possible.

Das Hochschwenken der Bühnenplattform 16 bzw. der Bühnenplattform 20, die der Bühnenplattform 16 gegenüberliegt, erfolgt über die beiden Stellzylinder-Kolbenanordnungen 21 bzw. 22, wobei die Kolbenstange 23 bzw. 24 der Zylinder jeweils an einem Torsionsstab 25 bzw. 26 angreift, der starr mit den Lenkern 14 verbunden ist. Die Anlenkung der Kolbenstange 24 beispielsweise an dem Torsionsstab 26 erfolgt unter Zwischenschalten einer Winkelscheibe 27, so daß dadurch der erforderliche Hebelarm geschaffen wird. Durch Einziehen der Kolbenstange 23 bzw. 24 sind die Bühnenplattformen in die in Fig. 1 dargestellte Arbeitslage hebbar.The stage platform 16 or the stage platform 20, which lies opposite the stage platform 16, is pivoted upward via the two actuating cylinder piston arrangements 21 and 22, the piston rods 23 and 24 of the cylinders each being connected to a torsion bar 25 and 26 attacks, which is rigidly connected to the arms 14. The articulation of the piston rod 24, for example on the torsion bar 26, takes place with the interposition of an angle disk 27, so that the necessary lever arm is thereby created. By pulling in the piston rod 23 or 24, the platform platforms can be lifted into the working position shown in FIG. 1.

Die Bühnenplattformen 16 und 20 können aus begehbaren Gitterrosten gebildet sein; Zwischenstellungen als Arbeitsstellungen können festgestellt werden. Das Feststellen erfolgt dabei über hydraulische Sicherheitsventile.The stage platforms 16 and 20 can be formed from walk-on gratings; Intermediate positions as working positions can be determined. The detection takes place via hydraulic safety valves.

Die Torsionsstäbe 25 und 26 tragen zur Verwindungssteifigkeit der gesamten Bühnenkonstruktion bei, wobei zu beachten ist, daß diese Bühnenkonstruktion mit ihrem Rahmenteil 10 den Drehschemel 4 im Bereich, wo er über die Dachoberfläche hinaussteht, umgreift.The torsion bars 25 and 26 contribute to the torsional rigidity of the entire stage construction, it being noted that this stage construction with its frame part 10 encompasses the turntable 4 in the area where it projects beyond the roof surface.

Bühnenumrandungen 28 und 29 sind als Parallelogrammgestänge ausgebildet, wobei die einzelnen Vertikalstäbe, beispielsweise der Vertikalstab 30, über ein Gelenk 31, ein Gelenk 32 und ein Gelenk 33 schwenkbar mit den vorgesehenen Horizontalstäben 39 und 40 verbunden ist.Stage borders 28 and 29 are designed as parallelogram linkages, the individual vertical bars, for example vertical bar 30, being pivotably connected to the horizontal bars 39 and 40 provided via a joint 31, a joint 32 and a joint 33.

Der Arretierung dieser Bühnenumrandungen 28 und 29 dienen Feststellbolzen 34.Locking bolts 34 serve to lock these stage borders 28 and 29.

An den Stirnseiten können entsprechende Stäbe 35 eingehängt werden, so daß dadurch die Bühne auf der dem Arbeitsstand 6 abgewandten und auch an der anderen Seite geschützt ist.Corresponding rods 35 can be attached to the end faces, so that the stage is thereby protected on the working stand 6 facing away and also on the other side.

Die Oberkante der beiden Bühnenplattformen 16 und 20 können mit der Oberkante des Auslegers 5 flächig fluchtend abschließen (Fig. 4). Selbstverständlich ist es auch möglich, die Bühnenplattformen 16 und 20 so zu gestalten, daß sie mit ihren oberen Kanten die Oberseite des Auslegers 5 übergreifen, so daß dadurch der Ausleger überdeckt ist.The upper edge of the two platform platforms 16 and 20 can be flush with the upper edge of the boom 5 (Fig. 4). Of course, it is also possible to design the stage platforms 16 and 20 in such a way that their upper edges overlap the top of the boom 5 so that the boom is covered.

Die Stellzylinder-Kolbenanordnung 21 und 22 ist mit den Zylindern im wesentlichen horizontal liegend angeordnet. Hierbei sind an entsprechenden Tragbalken 36 bzw. 37 taschenartige Aufnahmeräume 38 vorgesehen, in denen die Stellzylinder-Kolbenanordnungen 21 und 22 untergebracht werden können. Hierdurch wird eine raumsparende Anordnung geschaffen, die es ermöglicht, daß die Bühnenanordnung unterhalb des Auslegers 5 untergebracht werden kann und somit in zurückgeklappter Lage (Fig.4) die Arbeit des Auslegers 5 sowohl hinsichtlich der horizontalen Schwenkbewegung wie der vertikalen Hubbewegung überhaupt nicht behindert.The actuating cylinder piston arrangement 21 and 22 is arranged with the cylinders lying essentially horizontally. In this case, pocket-like receiving spaces 38 are provided on corresponding support beams 36 and 37, in which the actuating cylinder piston arrangements 21 and 22 can be accommodated. This creates a space-saving arrangement that enables the stage arrangement to be accommodated below the boom 5 and thus, in the folded-back position (FIG. 4), does not hinder the work of the boom 5 in terms of both the horizontal pivoting movement and the vertical lifting movement.

Aus Fig. 4 ist weiterhin erkennbar, daß die Bühne innerhalb des Fahrzeugbegrenzungsprofils »A« angeordnet ist und somit störungslos mitgeführt werden kann.From Fig. 4 it can also be seen that the stage is arranged within the vehicle limitation profile "A" and can therefore be carried without problems.
