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 rotatably mounted on a support bearing and / or höhenverschwenkbar mounted rotary and Ausfahrmast, and with a tip of a serving as an intermediate basket holder pivotally mounted in the region of its bottom work basket with the at least one parallel alignment of the ground plane is to be observed to a horizontal reference plane and with the work basket via a hinge in the horizontal plane is rotated.

Ein solcher Korbträger-Turm ist aus dem Prospektblatt »LEO 26-36 h, DIE Arbeitsbühnen auf Gummiketten von Teupen!« bekannt. Offenbart ist 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 known from the leaflet »LEO 26-36 h, the platforms on rubber tracks of Teupen!«. Disclosed is an aerial work platform in which the work basket is movably held by a head holder on a höhenverschwenkbar mounted on a stand, telescopic boom. The work basket is supported by a parallel guide, which has relatively long arm parts. The disadvantage is that take a relatively large weight at the top of the boom is that limits the extensibility and load of the work basket.

Die DE 30 40 882 C2 beschreibt eine Hubarbeitsbühne, die ortsveränderlich auf einem Fahrrahmen montiert werden kann. 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.The DE 30 40 882 C2 describes an aerial work platform, which can be mounted on a mobile frame movable. At the end of the höhenverschwenkbaren, rotatable cantilever arm, a pivotable Korbarm is mounted, which is additionally pivotable relative to the boom. This Korbarm allows a bypass of obstacles. Arm and Korbarm lie in a single vertical plane. The workplace shape or the work basket are pivotally mounted at the end of the basket and are always held parallel to a reference plane via a parallel guide.

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.A disadvantage of this design is the additional length and height required for the basket holder. The only pivot point on the aerial work platform is very far away from the work cage, allowing only very rough positioning.

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 also known to the person skilled in the art, the work cage can be fastened symmetrically to the central axis or, as is often known in practice, laterally on the basket. If the platform hangs sideways next to the basket holder, the stability is greatly reduced when the boom is fully extended. The enlargement of the accessible area in a small space requires time-consuming adjustments on the boom and on the Corbarm.

Die US 5 868 218 zeigt ein Fahrzeug mit einem Korbträger-turm, bei dem der Korb zwar außerhalb der Mitte seines rechteckigen Bodens gelagert ist. Der Boden muss jedoch für das Lager mit einem Gitterrahmen ausgesteift sein, wodurch das Fahrzeuggewicht erhöht.The US 5,868,218 shows a vehicle with a basket carrier tower, in which the basket is indeed stored outside the center of its rectangular bottom. However, the floor must be stiffened for the bearing with a grid frame, which increases the vehicle weight.

Der Erfindung liegt die Aufgabe zugrunde, einen Korbträger-Turm für Hubarbeitsbühnen der eingangs genannten Art so zu verbessern, dass bei geringer Transportlänge eine große seitliche Beweglichkeit gegeben ist und insbesondere in Nischen sowie hinter Rücksprüngen in Gebäudefassaden mit dem Arbeitskorb gearbeitet werden kann.The invention has for its object to improve a basket carrier tower for aerial work platforms of the type mentioned so that at low transport length a large lateral mobility is given and can be worked in particular in niches and behind recesses in building facades with the work basket.

Diese Aufgabe wird gelöst durch einen Korbträger-Turm mit den Merkmalen des Anspruchs 1.This object is achieved by a basket carrier tower with the features of claim 1.

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 Arbeitskorbs 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 Arbeitskorbs wird demnach die Lagerhülse in einer Rechteck-Ecke angeordnet. Die Kombination aus Stützzapfen und Lagerhülse ist dabei so angeordnet, dass der Arbeitskorb sich in beiden Schwenkrichtungen um wenigstens 180° um eine Ausgangsstellung verdrehen kann.An increased mobility of the working basket can be achieved in that the bearing sleeve is not centrally mounted on one side of the basket bottom, but that in plan view of the bottom of the work basket, the position of the bearing sleeve from the centroid occupies the constructive maximum distance. In this case, "structurally possible" means that, taking into account known strength values and known static conditions, the bearing sleeve is positioned as close as possible or even outside the edge of the base of the working basket. In a rectangular shape of the bottom of the work basket, therefore, the bearing sleeve is arranged in a rectangle corner. The combination of support pin and bearing sleeve is arranged so that the work basket can rotate in both pivot directions by at least 180 ° to an initial position.

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 connection of the working means relative to the basket holder contributes, when the bearing sleeve is rigidly connected to the work basket in the region of the ground plane and / or at its, projecting beyond the bottom head.

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 supported on a bolt which passes horizontally through the basket holder, so that a lightweight construction is possible. In particular, the work basket can be supported on a flange plate connected to the basket holder.

Um zu einer flachen Bauweise für den Antrieb in horizontalen Schwenkrichtungen zu kommen, umfaßt der Antrieb für die Bewegung des Arbeitskorbs vorzugsweise einen Hydraulikzylinder.In order to achieve a flat design for the drive in horizontal pivoting directions, the drive for the movement of the work basket preferably comprises 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 done via a spindle or a linear guide or 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 may be surrounded by a friction or toothed belt or a chain, so that the hydraulic cylinder, which is part of the working basket, moves via a connecting element a friction or toothed 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 drive via a connecting element and a chain or a rope with which the work basket in the horizontal is movable.

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 lightweight and yet rigid construction, which can also be carried self-supporting, arises when at least the bottom of the work basket is made of an aluminum foam material which is at least two layers and a bubble, 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 work basket can be connected to a plurality of, preferably welded, railing posts fastened to the circumference of the floor and to handrails, knee rails and baseboards connected thereto, which together form a self-supporting construction.

On one side of the work basket 1 with a hinged rise 10 (not shown) provided to enter the work basket can.

In einer Ecke der Bodenplatte 1.1.1, die gegenüber dem Aufstieg 10 (nicht dargestellt) angeordnet ist, ist so nah wie konstruktiv möglich am Rand der Bodenplatte 1.1.1 eine Lagerhülse 2 senkrecht zum Boden 1.1.1 eingeschweißt, die deutlich mit ihrem Kopfende 2.1 über dem Niveau des Bodens 1.1.1 endet. Die Lagerhülse 2 trägt damit den Arbeitskorb 5. Das hinausragende Kopfende 2.1 der Lagerhülse 2 ist am oberen Ende über ein Knotenblech 1.1.7 zusätzlich an den in der Ecke befindlichen Geländerpfosten 1.1.3 angeschlossen. Der Geländerpfosten ist seinerseits über Streben 1.1.8. mit den benachbarten Fußleisten 1.1.4 verbunden.In a corner of the bottom plate 1.1.1, which is opposite the rise 10 (not shown) is arranged as close as constructively possible at the edge of the bottom plate 1.1.1 a bearing sleeve 2 perpendicular to the bottom 1.1.1 welded, clearly with its head 2.1 above the level of the soil 1.1.1 ends. The bearing sleeve 2 thus carries the work basket 5. The protruding headboard 2.1 of the bearing sleeve 2 is additionally connected at the upper end via a gusset plate 1.1.7 to the railing post 1.1.3 located in the corner. The railing post is in turn on struts 1.1.8. connected to the adjacent baseboards 1.1.4.

Die Lagerhülse 2 ist durch den bereits beschriebenen Stützzapfen 5 durchsetzt. Der Stützzapfen 5 ragt etwas über den Rand der Lagerhülse 2, so dass zur Sicherung des Arbeitskorbes 1 der Stützzapfen gegen ein Herausgleiten aus der Lagerhülse gesichert werden muss. Dies geschieht durch eine auf der oberen Kreisfläche des Stützzapfens 5 befestigte Scheibe 5.3.The bearing sleeve 2 is penetrated by the support pin 5 already described. The support pin 5 protrudes slightly beyond the edge of the bearing sleeve 2, so that for securing the working basket 1, the support pin must be secured against slipping out of the bearing sleeve. This is done by a mounted on the upper circular surface of the support pin 5 disc 5.3.

Mit dem Stützzapfen 5 ist, wie bereits beschrieben, eine Zahnriemenscheibe 12 verbunden. Mit 16 sind die Elemente eines Drehantriebs für die Zahnriemenscheibe 12 und damit des Arbeitskorbes 1 bezeichnet. Ein flach gebautes Zahnriemengetriebe 6, das unterhalb der Bodenplatte in einer Mulde untergebracht ist, umfasst die nachfolgend beschriebenen und in Fig.4 gezeigten Teile.As already described, a toothed belt pulley 12 is connected to the support pin 5. 16, the elements of a rotary drive for the toothed belt pulley 12 and thus of the working basket 1 are designated. A flat-built toothed belt transmission 6, which is housed below the bottom plate in a trough, comprises the below-described and in Figure 4 shown parts.

Ein Zahnriemen 6.4, der die Zahnriemenscheibe 12 auf dem Stützzapfen 5 umschlingt, umschlingt auch eine zweite gleich große Zahnriemenscheibe 12.2, die an der Unterseite der Bodenplatte 1.1.1 des Arbeitskorb 1 auf einem Zapfen 6.5 drehbar befestigt ist. Um den Zahnriemen spannen und lösen zu können, ist der Zapfen 6.5 in einem Langloch 1.1.1.1 in der Bodenplatte 1.1.1 verschieblich angebracht; zur Sicherung ist der Zapfen 6.5 mit einer Spannvorrichtung 6.7 versehen. Die Rotationsachsen der beiden beabstandeten und auf gleichem Höhenniveau befindlichen Riemenscheiben 12, 12.2 verlaufen parallel, wobei die gerade Verbindungslinie der Riemenscheiben 12,12.2 parallel zur längeren Seite der Bodenplatte 1.1.1 verläuft.A toothed belt 6.4, which wraps around the toothed belt pulley 12 on the support pin 5, also wraps around a second equal-sized toothed pulley 12.2, which is rotatably mounted on the underside of the bottom plate 1.1.1 of the work basket 1 on a pin 6.5. In order to tension the timing belt and solve, the pin 6.5 is slidably mounted in a slot 1.1.1.1 in the bottom plate 1.1.1; to secure the pin 6.5 is provided with a jig 6.7. The axes of rotation of the two spaced and at the same height level pulleys 12, 12.2 are parallel, wherein the straight line connecting the pulleys 12,12.2 runs parallel to the longer side of the bottom plate 1.1.1.

Parallel zum tangentialen Verlauf des Zahnriemens 6.4 ist in Höhe der Riemenscheiben 12,12.2 ein Hydraulikzylinder 6.1 unter der Bodenplatte 1.1.1 am Arbeitskorb 1 angeordnet, dessen Kolbenstange 6.1.1 fest mit dem Riemen 6.4 über ein Verbindungselement 6.6 verbunden ist. Die translatorische Bewegung der Kolbenstange 6.1.1 wird über die Riemenscheiben 12,12.2 in eine Rotation des Arbeitskorbes 1 um den Stützzapfen 5 gewandelt. Die Durchmesser der Riemenscheiben 5.1,6.3 und deren Abstand bzw. der Hubweg der Kolbenstange 6.1.1 sind so gewählt, dass der Arbeitskorb 1 aus einer Ausgangsstellung heraus, einen Drehwinkel von 180° überstreifen kann. Verlängert man den Hub des Hydraulikzylinders 6.1 bzw. der Kolbenstange 6.1.1 kann der Arbeitskorb 1 um Winkel über 180° schwenken.Parallel to the tangential course of the toothed belt 6.4 is at the level of the pulleys 12,12.2 a hydraulic cylinder 6.1 under the bottom plate 1.1.1 arranged on the work basket 1, the piston rod 6.1.1 is firmly connected to the belt 6.4 via a connecting element 6.6. The translatory movement of the piston rod 6.1.1 is converted by the pulleys 12,12.2 in a rotation of the working basket 1 to the support pin 5. The diameter of the pulleys 5.1,6.3 and their distance or the stroke of the piston rod 6.1.1 are chosen so that the work basket 1 from an initial position out, can cover a rotation angle of 180 °. If the stroke of the hydraulic cylinder 6.1 or the piston rod 6.1.1 is lengthened, the working basket 1 can be pivoted through angles of more than 180 °.

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. Figure 5 shows the attached to the turning 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 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 the optimal position of the working platform for working on a saddle roof or a wall projection is shown. Depending on requirements, the working width or the working depth of the turned rectangular base plate is 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 provide excellent accessibility around a central working center, which is also the pivot point of the working basket. On a long Korbarm, as described in the prior art, which causes additional costs and further weight can be dispensed with.

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, the lightweight construction that results with the aluminum foam material allows an unconventional arrangement of the pivot point 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.Also, the profile parts of the rotary and Ausfahrmastes can be made in place of steel structures or conventional aluminum structures of an aluminum foam material. This results in much higher extension lengths for the telescopic structure. It is advantageous that at comparatively low permissible total weight of the vehicle and in compliance with all safety regulations and safety criteria, a greater extension length with the same work basket size is achievable compared to other vehicles of the same weight class.

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.Similarly, rigid sandwich structures can be 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 form the bottom plate. The intermediate layer consists in particular of thin sheet metal honeycomb or foamed ceramic or metal (preferably aluminum). Also plastic composite material with aligned carbon fibers as reinforcement is suitable.
