Description

Die Erfindung betrifft einen Korbträger-Turm, insbesondere für Hubarbeitsbühnen, bestehend aus auf einem Stützlager drehbar und/oder höhenverschwenkbar angebrachten Dreh- und Ausfahrmast, und mit einem an dessen Spitze über einen als Zwischenglied dienenden Korbhalter schwenkbar im Bereich seines Bodens befestigten Arbeitskorb, mit dem wenigstens eine Parallelausrichtung der Bodenebene zu einer horizontalen Bezugsebene einzuhalten ist und mit der der Arbeitskorb über ein Drehgelenk auch in der horizontalen Ebene verdrehbar ist.The invention relates to a basket carrier tower, in particular for aerial work platforms, consisting of on a support bearing rotatable and / or höhenverschwenkbar mounted rotary and Extension mast, and with one at the top of one as Intermediate serving basket holder pivotally in the area his floor-mounted work basket, with which at least a parallel orientation of the ground plane to a horizontal Reference level is adhered to and with the work basket also rotatable in the horizontal plane via a swivel joint is.

Ein solcher Korbträger-Turm ist aus dem Prospektblatt »LEO 26-36 h, DIE Arbeitsbühnen auf Gummiketten von Teupen!« zu erkennen. Das Prospektblatt zeigt auf seiner Titelseite eine Hubarbeitsbühne, bei der der Arbeitskorb beweglich über einen Kopfhalter an einem höhenverschwenkbar, auf einem Standrahmen montierten, teleskopierbaren Auslegerarm gehalten ist. Der Arbeitskorb wird über eine parallele Führung, die über relativ lange Armteile verfügt, getragen. Nachteilig ist, dass an der Spitze des Auslegerarmes ein relativ großes Gewicht aufzunehmen ist, das die Ausfahrbarkeit und Belastung des Arbeitskorbes beschränkt. Such a basket carrier tower is from the leaflet »LEO 26-36 h, the work platforms on Teupen rubber tracks! " detect. The leaflet shows one on its front page Aerial work platform with movable work platform above a head holder on a höhenverschwenkbar, on one Stand frame mounted, telescopic boom held is. The work basket is made via a parallel guide, which has relatively long arm parts worn. adversely is that at the top of the boom a relative To take up great weight is that the extensibility and Load of the work basket limited.

Die DE 30 40 882 C2 beschreibt eine Hubarbeitsbühne, die ortsveränderlich auf einem Fahrrahmen montiert werden kann.DE 30 40 882 C2 describes an aerial work platform, the can be mounted mobile on a traveling frame.

Am Ende des höhenverschwenkbaren, drehbaren Auslegerarmes ist ein schwenkbarer Korbarm angebracht, der gegenüber dem Auslegerarm zusätzlich schwenkbar ist. Dieser Korbarm ermöglicht eine Umgehung von Hindernissen. Auslegerarm und Korbarm liegen in einer einzigen vertikalen Ebene. Die Arbeitsplatzform bzw. der Arbeitskorb sind am Ende des Korbarms schwenkbar angebracht und werden über eine Parallelführung stets parallel zu einer Bezugsebene gehalten.At the end of the height-swiveling, rotatable cantilever arm a swiveling basket bar is attached, opposite to the Arm is additionally pivotable. This Corbarm allows a bypass of obstacles. Cantilever arm and Korbarm lie in a single vertical plane. The workplace form or the work basket are at the end of the Korbarms pivotally mounted and are via a parallel guide always kept parallel to a reference plane.

Nachteilig bei dieser Ausführung ist die zusätzliche Baulänge und Bauhöhe, die für den Korbhalter benötigt werden. Der einzige Drehpunkt der Hubarbeitsbühne ist sehr weit von dem Arbeitskorb entfernt, wodurch eine nur sehr grobe Positionierung ermöglicht wird.The disadvantage of this design is the additional length and height required for the basket holder. The only fulcrum of the aerial work platform is very far from removed from the work basket, creating a very rough positioning is possible.

Wie dem Fachmann weiterhin bekannt ist, kann der Arbeitskorb symmetrisch zur Mittelachse, oder, wie in der Praxis vielfach bekannt, seitlich am Korbarm befestigt werden. Hängt der Arbeitskorb seitlich neben dem Korbhalter, wird die Standsicherheit bei vollständig ausgefahrenem Auslegerarm stark reduziert. Die Vergrößerung des zugänglichen Bereichs auf engem Raum erfordert zeitraubende Verstellungen am Ausleger und am Korbarm.As is further known to those skilled in the art, the work basket symmetrical to the central axis, or, as in practice often known to be attached to the side of the Korbarm. The work basket hangs laterally next to the basket holder, will the stability with fully extended boom greatly reduced. The enlargement of the accessible Space in a small space requires time-consuming adjustments on the jib and on the beam.

Der Erfindung liegt die Aufgabe zugrunde, einen eingangs beschriebenen Korbträger-Turm so zu gestalten, dass die Teile des Zwischengliedes so kurz und leicht wie möglich gemacht werden können, dass die Standsicherheit und Belastbarkeit im Gebrauch erhöht werden und dass die Zugänglichkeit in Innenräume nicht eingeschränkt ist. The invention is based on the object, an entrance described basket carrier tower to be designed so that the Parts of the pontic as short and light as possible can be made that the stability and resilience to be increased in use and that accessibility is not restricted in interiors.

Diese Aufgaben wird gelöst durch einen Korbträger-Turm, insbesondere für Hubarbeitsbühnen, der dadurch gekennzeichnet ist, dass der Korbhalter einen vertikalen starren Stützzapfen umfaßt, der in eine am Korbboden gehaltene Lagerhülse eingreift und der an einem Korbhalter an der Spitze des Dreh- und Ausfahrmastes gehaltert ist, und dadurch, dass mit einem Antrieb, dem der Stützzapfen als Bezug dient, der Arbeitskorb in der horizontalen Ebene verdrehbar ist.These tasks are solved by a basket carrier tower, in particular for aerial work platforms, characterized is that the basket holder is a vertical rigid Support pin comprises, which is held in a basket bottom bearing sleeve engages and the at a basket holder at the top of the turntable and extension mast is supported, and thereby that with a drive, the support pin as a reference serves, the work basket in the horizontal plane rotatable is.

Eine erhöhte Beweglichkeit des Arbeitskorbes kann dadurch erreicht werden, dass dessen Lagerhülse nicht mittig an einer Seite des Korbbodens angebracht wird, sondern dass in Draufsicht auf den Boden des Arbeitskorb die Position der Lagerhülse vom Flächenschwerpunkt die konstruktiv maximale Entfernung einnimmt. Dabei bedeutet »konstruktiv möglich«, dass unter Berücksichtigung bekannter Festigkeitswerte und bekannter statischer Voraussetzungen die Lagerhülse möglichst nahe oder sogar außerhalb des Randes der Standfläche des Arbeitskorbes positioniert wird. Bei einer Rechteckform des Bodens des Arbeitskorb wird demnach die Lagerhülse in einer Rechteck-Ecke angeordnet.An increased mobility of the work basket can thereby be achieved that its bearing sleeve is not centered on a Side of the basket bottom is attached, but that in Top view of the floor of the work basket the position of the Bearing sleeve from the centroid of the constructive maximum Distance takes. This means "constructively possible", that taking into account known strength values and known static conditions, the bearing sleeve as possible near or even outside the edge of the stand of the working basket is positioned. In a rectangular shape the bottom of the work basket is therefore the bearing sleeve in arranged a rectangle corner.

Vorzugsweise wird die Kombination aus Stützzapfen und Lagerhülse so angeordnet, dass der Arbeitskorb sich in beiden Schwenkrichtungen um wenigstens 180° um eine Ausgangsstellung verdrehen kann.Preferably, the combination of support pin and bearing sleeve arranged so that the work basket is in both Pivoting directions by at least 180 ° about a starting position can twist.

Zur Verbesserung der Starrheit einer Verbindung der Arbeitsmittel gegenüber dem Korbhalter trägt bei, wenn die Lagerhülse im Bereich der Bodenebene und/oder an ihrem, über den Boden hinausragenden Kopfende starr mit dem Arbeitskorb verbunden wird. To improve the rigidity of a compound of work equipment opposite the basket holder contributes when the Bearing sleeve in the area of the ground level and / or on her, The headboard protruding from the floor is rigid with the work basket is connected.

Der Stützzapfen kann sich direkt oder indirekt auf einem Bolzen, der horizontal den Korbhalter durchsetzt, abstützen, so dass eine leichte Baukonstruktion möglich ist. Insbesondere kann sich der Arbeitskorb auf einer mit dem Korbhalter verbundenen Flanschplatte abstützen.The support pin can be directly or indirectly on a Bolt horizontally through the basket holder, support, so that a lightweight construction is possible. Especially can the work basket on one with the basket holder support connected flange plate.

Um zu einer flachen Bauweise für den Antrieb in horizontalen Schwenkrichtungen zu kommen, umfaßt der Antrieb für die Bewegung des Arbeitskorbs vorzugsweise einen Hydraulikzylinder.To be a flat design for driving in horizontal Pivoting directions include the drive for the Movement of the work basket preferably a hydraulic cylinder.

Der Antrieb für die horizontale Bewegung des Arbeitskorbs kann auch über eine Spindel oder eine Linearführung oder einen Pneumatikzylinder erfolgen.The drive for the horizontal movement of the work basket can also be via a spindle or a linear guide or take a pneumatic cylinder.

Der Stützzapfen kann von einem Reib- oder Zahnriemen oder einer Kette umgeben sein, so dass der Hydraulikzylinder, der Teil des Arbeitskorbes ist, über ein Verbindungselement einen Reib- oder Zahnriemen bewegt.The support pin can from a friction or timing belt or be surrounded by a chain, so that the hydraulic cylinder, the part of the working basket is, via a connecting element moved a friction or timing belt.

Der Hydraulikzylinder kann über ein Verbindungselement auch eine Kette oder ein Seil antreiben, mit der der Arbeitskorb in der Horizontalen bewegbar ist.The hydraulic cylinder can also be connected via a connecting element driving a chain or a rope with which the work basket is movable in the horizontal.

Eine besonders leichte und trotzdem steife Konstruktion, die auch selbsttragend ausgeführt sein kann, ergibt sich dann, wenn wenigstens der Boden des Arbeitskorbs aus einem Aluminium-Schaumwerkstoff gefertigt ist, der wenigstens zweischichtig ist und aus einer blasigen, geschäumtem Aluminiumschicht und einer außen liegenden massiven Aluminiumschicht besteht. A particularly light and yet stiff construction, which can also be carried out self-supporting results then, if at least the bottom of the work basket from a Aluminum foam material is made, at least is two-layered and made of a bubbly, foamed aluminum layer and an external solid aluminum layer consists.

Der Arbeitskorb kann mit mehreren, am Umfang des Bodens befestigten, vorzugsweise verschweißten, Geländerpfosten sowie mit diesen verbundenen Handläufen, Knieleisten und Fußleisten verbunden sein, die zusammen eine selbsttragende Konstruktion bilden.The working cage can be equipped with several, attached to the circumference of the floor, preferably welded, railing posts as well with these connected handrails, knee rails and baseboards be connected, which together a self-supporting Construct construction.

    Fig.5 zeigt den am Dreh- und Ausfahrmast 7 befestigten Arbeitskorb 1 in verschiedenen Positionen in den Draufsichten und den dazugehörigen Seitenansichten. Pos.1 ist die sogenannte Ausgangsposition, aus der der Arbeitskorb im Uhrzeigersinn um 180° gedreht wird. Die Ausgangsposition ist gleichzeitig die Transportposition. Der Arbeitskorb schließt mit dem Dreh- und Auslegerarm 7 und dem Korbarm 3 ab, so daß die Baulänge ihr kleinstes Maß erreicht.5 shows the attached to the rotary and Ausfahrmast 7 work basket 1 in different positions in the plan views and the associated side views. Pos.1 is the so-called Starting position from which the work basket is clockwise rotated by 180 °. The starting position is at the same time the transport position. The work basket closes with the rotary and boom 7 and the Korbarm. 3 so that the length reaches its smallest measure.

    In die Pos. 2 und die Pos.3 ist die optimale Position der Arbeitsplattform für Arbeiten an einem Satteldach oder einem Mauervorsprung dargestellt. Je nach Bedarf wird die Arbeitsbreite oder die Arbeitstiefe der gedrehten rechteckigen Bodenplatte genutzt.In Pos. 2 and Pos.3 is the optimal position of Working platform for work on a pitched roof or a Wall projection shown. As required, the working width or the working depth of the turned rectangular Bottom plate used.

    Alle Positionen ermöglichen den optimalen Zugang in Bauwerksnischen und bieten eine sehr gute allseitige Erreichbarkeit um einen zentralen Arbeitsmittelpunkt, der gleichzeitig der Drehpunkt des Arbeitskorbes ist. Auf einen langen Korbarm, so wie im Stand der Technik beschrieben, der zusätzliche Kosten und weiteres Gewicht verursacht, kann verzichtet werden.All positions allow optimal access in building niches and offer a very good accessibility around a central work center, at the same time the pivot point of the working basket is. On a long Korbarm, as described in the prior art, the additional costs and may cause further weight be waived.

    Wesentliche Teile des Arbeitskorbes, insbesondere die Bodenplatte, bestehen aus einem Aluminium-Schaumwerkstoff. Die Verwendung von Aluminium-Schaumwerkstoff für Fahrzeugteile ist an sich bekannt. Im vorliegenden Falle ermöglicht die leichte Bauweise, die sich mit dem Aluminium-Schaumwerkstoff ergibt, eine unkonventionelle Anordnung des Drehpunktes des Arbeitskorbes.Essential parts of the working basket, in particular the bottom plate, consist of an aluminum foam material. The use of aluminum foam material for vehicle parts is known per se. In the present case allows the lightweight construction, which deals with the aluminum foam material results in an unconventional arrangement of the Fulcrum of the working basket.

    Auch die Profilteile des Dreh- und Ausfahrmastes können an Stelle von Stahlkonstruktionen oder konventioneller Aluminiumkonstruktionen aus einem Aluminium-Schaumwerkstoff hergestellt werden. Hierdurch ergeben sich wesentlich höhere Ausfahrlängen für das teleskopierbare Gebilde. Vorteilhaft ist, dass bei vergleichsweise geringem zulässigem Gesamtgewicht des Fahrzeugs und unter Beachtung aller Sicherheitsbestimmungen und Sicherheitskriterien eine größere Ausfahrlänge bei gleicher Arbeitskorb-Größe zu im Vergleich zu anderen Fahrzeugen gleicher Gewichtsklasse erreichbar ist.The profile parts of the turntable and extension mast can also Place of steel structures or conventional aluminum structures made of an aluminum foam material become. This results in much higher Extension lengths for the telescopic structure. Advantageous is that at comparatively low gross vehicle weight of the vehicle and in compliance with all safety regulations and safety criteria a longer extension length at the same work basket size compared to others Vehicles of the same weight class can be reached.

    In ähnlicher Weise können auch biegesteife Sandwich-Strukturen für die Herstellung des Bodens eingesetzt werden. Die Sandwich-Struktur besteht aus einer relativ biegesteifen Zwischenlage mit beidseitigen dünnen Blechlagen, die zusammen die Bodenplatte ergeben. Die Zwischenlage besteht insbesondere aus Dünnblechwaben oder aus geschäumtem Keramik oder Metall (vorzugsweise Aluminium). Auch Kunststoff-Verbundmaterial mit ausgerichteten Carbonfasern als Armierung ist geeignet.Likewise, rigid sandwich structures can also be used used for the production of the soil. The sandwich structure consists of a relatively rigid Intermediate layer with thin metal layers on both sides, which together give the bottom plate. The liner exists in particular made of thin sheet metal honeycomb or foamed Ceramic or metal (preferably aluminum). Also plastic composite material with oriented carbon fibers as Reinforcement is suitable.
