Description

Die Erfindung betrifft eine selbstfahrende Hubarbeitsbühne, insbesondere eine selbstfahrende Scherenarbeitsbühne, mit den Merkmalen des Oberbegriffs des Anspruches 1 beziehungsweise des Anspruches 2. Eine solche, beispielsweise in DE 296 10 630 U1 dargestellte Maschine weist ein Fahrgestell mit einer Anzahl von Rädern auf. Im Allgemeinen handelt es sich um vier Räder. Die Lasthebemaschine umfasst ferner einen Lasthebemechanismus, beispielsweise eine Ausfahrtvorrichtung. Die Ausfahrvorrichtung stützt sich mit ihrem unteren Ende auf das Fahrgestell der Maschine, und mit ihrem oberen Ende trägt sie eine Arbeitsbühne. Die Ausfahrvorrichtung kann ein Scherenmechanismus sein, aber auch ein anderer Mechanismus wie beispielsweise eine Teleskopeinrichtung. Im bestimmungsgemäßen Einsatz befinden sich auf der Bühne stets Personen, nämlich Monteure. Die Arbeitsbühne darf gemäß BGR-Vorschriften zum reinen Heben von Lasten nicht verwendet werden. Sie wird speziell eingesetzt für Montage-, Reparatur- und Wartungsarbeiten in allen erreichbaren Höhen. Als Einsatzort kommen Industrieanlagen, aber auch Neubaustellen in Betracht.The invention relates to a self-propelled aerial work platform, in particular a self-propelled scissor lift, with the features of the preamble of claim 1 and claim 2. Such, for example, in DE 296 10 630 U1 The machine shown has a chassis with a number of wheels. In general, there are four wheels. The load lifting machine further comprises a lifting mechanism, such as an exit device. The extension device is supported by its lower end on the chassis of the machine, and with its upper end it carries a working platform. The extension device may be a scissors mechanism, but also another mechanism such as a telescopic device. When used as intended, there are always persons on the stage, namely fitters. The platform may not be used in accordance with BGR regulations for lifting loads only. It is specially used for assembly, repair and maintenance work in all accessible heights. As a place of work industrial plants, but also new construction sites come into consideration.

Solche fahrbaren Lasthebemaschinen werden überall in der industriellen Technik eingesetzt. Ein wichtiges Einsatzgebiet ist das Beladen und Entladen von Hochregalen. Die Arbeitshöhe kann 20 Meter und mehr erreichen.Such mobile lifting machines are widely used in industrial engineering. An important field of application is the loading and unloading of high shelves. The working height can reach 20 meters and more.

Eine wichtige Eigenschaft solcher fahrbaren Lasthebemaschinen ist deren Standsicherheit. Diese hängt von dem Radabstand ab - gemessen quer zur Fahrtrichtung. Da der Radabstand begrenzt ist, zum Beispiel durch die geringe Breite der Fahrgassen in Hochregallagern, ist auch die Standsicherheit nur begrenzt. Um die Standsicherheit während der Arbeitsphasen der Maschine zu erhöhen, ist eine solche Maschine im Allgemeinen mit Stützeinrichtungen ausgestattet. Die Stützeinrichtungen befinden sich - in Draufsicht auf die Maschine gesehen - im Bereich der Räder, und zwar außerhalb der Räder. Je größer der gegenseitige Abstand zweier Stützeinrichtungen ist, die beidseits der Längsmittelachse der Maschine angeordnet sind, desto größer ist die Standsicherheit. Man ist daher bestrebt, die Stützeinrichtungen so nah wie möglich an die Umrisslinie der Maschine zu legen. Die Ausdrucksweise "Umrisslinie" ist gleich der Außenkontur der Maschine, in Draufsicht gesehen.An important feature of such mobile lifting machines is their stability. This depends on the wheel distance - measured transversely to the direction of travel. Since the wheelbase is limited, for example by the small width of the tramlines in high-bay warehouses, the stability is limited. In order to increase the stability during the working phases of the machine, such a machine is generally equipped with support means. The support means are - seen in plan view of the machine - in the area of the wheels, outside the wheels. The greater the mutual distance of two support devices, which are arranged on both sides of the longitudinal center axis of the machine, the larger the Stability. It is therefore desirable to place the support devices as close as possible to the outline of the machine. The expression "outline" is equal to the outer contour of the machine, seen in plan view.

Vorausgesetzt eine Arbeitsbühne steht auf dem Untergrund absolut eben, bringt das Abstützen innerhalb der Fahrzeugbreite keine beziehungsweise nur eine geringe zusätzliche Standsicherheit. Lediglich die leichte Bewegung in den Gummirädern wird hier ausgeschlossen. Die Stützen haben die Aufgabe, die Maschine unabhängig von den Bodenverhältnissen immer in eine nahezu ebene Arbeitsposition zu bringen. Diese dann gegebene ebene Arbeitsposition ergibt die bestmögliche Standsicherheit. Im Allgemeinen ist eine fahrbare Arbeitsbühne ohne Stützen. Die angebrachten Stützen werden jedoch in letzter Zeit immer häufiger von den Kunden gefordert, um eben den oben genannten Vorteil zu erreichen und der Maschine ein absolut senkrechtes Hochfahren, unabhängig von den gegebenen Bodenneigungen zu gewährleisten. Derselbe Maschinentyp wird auch ohne die Option Stützen gebaut.Assuming a platform is absolutely level on the ground, the support within the vehicle width brings no or only a little additional stability. Only the slight movement in the rubber wheels is excluded here. The supports have the task to bring the machine always in a nearly flat working position, regardless of the soil conditions. This then given level working position gives the best possible stability. In general, a mobile work platform without supports. However, the props have recently been demanded more and more frequently by customers to achieve the above advantage and to ensure the machine an absolutely vertical start, regardless of the given ground slopes. The same machine type is also built without the option supports.

Jede Stützeinrichtung umfasst eine Stütze und einen Stützteller. Der Stützteller ist an das untere Ende der Stütze gelenkig angeschlossen, um Unebenheiten des Bodens wie beispielsweise Schwellen ausgleichen zu können. Die Stütze ist im Allgemeinen eine Stange, die Bestandteil eines Teleskopmechanismus ist.Each support means comprises a support and a support plate. The support plate is hingedly connected to the lower end of the support to compensate for unevenness of the soil such as thresholds. The support is generally a rod that is part of a telescopic mechanism.

Im Hinblick auf die häufig begrenzten Platzverhältnisse - wiederum vor allem in Hochregallagern - sind der Breite der Maschine Grenzen gesetzt. Die genannte Umrisslinie darf somit auf keinen Fall überschritten werden. Da der Stützteller einer Stütze über deren Längsachse hinausragt, im Aufriss gesehen, kann die Stütze selbst nicht an der Umrisslinie liegen, sondern innerhalb der Umrisslinie.In view of the often limited space available - again, especially in high-bay warehouses - the width of the machine limits. The mentioned outline must therefore not be exceeded in any case. Since the support plate of a support extends beyond its longitudinal axis, seen in elevation, the support itself can not lie on the outline, but within the outline.

Der Erfindung liegt die Aufgabe zugrunde, eine selbstfahrende Hubarbeitsbühne der genannten Art derart zu gestalten, dass deren Standsicherheit beim Einsatz von Stützeinrichtungen erhöht wird, dass aber die Umrisslinie nicht überschritten wird, und dass keinerlei Teile der Stützeinrichtung, vor allem der Stützteller, nicht über diese Linie hinausragt.The invention has for its object to make a self-propelled aerial work platform of the type mentioned in such a way that their stability is increased when using support means, but that does not exceed the outline is, and that no parts of the support means, especially the support plate, does not protrude beyond this line.

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.

Die Lösung besteht in Folgendem:

  • das Gelenk ist ein Kardangelenk mit zwei zueinander rechtwinklig verlaufenden Gelenkzapfen
  • ein erster der beiden Gelenkzapfen befindet sich näher an der Umrisslinie der Maschine, als die Längsmittelachse der Stütze.
The solution consists of the following:
  • The joint is a universal joint with two mutually perpendicular pivot pin
  • a first of the two pivot pins is located closer to the outline of the machine than the longitudinal center axis of the support.

Der erste der beiden Gelenkzapfen wird sich im Allgemeinen parallel zur Längsmittelachse des Fahrzeuges erstrecken, in Draufsicht gesehen.The first of the two pivot pins will extend generally parallel to the longitudinal center axis of the vehicle, seen in plan view.

Ist die Stützeinrichtung in Funktion, und liegt der Stützteller demgemäß fest am Boden an, so verläuft der Stützkraftfluss vom Stützteller nach oben zu dem genannten ersten der beiden Gelenkzapfen, wird sodann umgelenkt - im Allgemeinen um 90 Grad - zum zweiten Gelenkzapfen, wird sodann erneut umgelenkt, wiederum im Allgemeinen um 90 Grad, und gelangt zur Stütze, die mehr oder minder senkrecht steht.If the support device is in operation, and the support plate is accordingly fixed to the ground, the support force flow from the support plate up to the said first of the two pivot pin is then deflected - generally by 90 degrees - to the second pivot pin, is then deflected again , again generally at 90 degrees, and gets to the support, which is more or less vertical.

Auf diese Weise wird der wirksame Abstand zweier Stützeinrichtungen - quer zur Fahrtrichtung gesehen - vergrößert. Die Vergrößerung mag im Einzelfall nur wenige Zentimeter bewirken. Sie erhöht jedoch die Standfestigkeit außerordentlich.In this way, the effective distance between two support devices - viewed transversely to the direction of travel - increased. The magnification may cause only a few centimeters in an individual case. However, it greatly increases the stability.

Eine weiter Lösung der Aufgabe ist in Anspruch 2 gekennzeichnet. Gemäß dieser Lösung wird statt des Kardangelenkes ein Kugelgelenk verwendet werden. Dieses ist wiederum zwischen das untere Ende der Stütze und den Stützteller geschaltet. Jedoch ist die Stütze vor dem Gelenk abgekröpft, und zwar in dem Sinne, dass sich das Kugelgelenk nahe an der Umrisslinie der Lasthebemaschine befindet, und somit außerhalb der Längsmittelachse der Stütze.A further solution of the problem is characterized in claim 2. According to this solution, a ball joint will be used instead of the universal joint. This in turn is connected between the lower end of the support and the support plate. However, the support is bent in front of the joint, in the sense that the ball joint is located close to the outline of the lifting machine, and thus outside the longitudinal center axis of the support.

In beiden Fällen wird sich der Stützteller im Betriebszustand nach innen erstrecken, das heißt von der Umrisslinie hinweg.In both cases, the support plate in the operating state will extend inwards, that is from the outline.

Bei der zweiten Ausführungsform mit dem Kugelgelenk wird man dafür sorgen, dass der Stützteller keine Drehbewegung ausführen kann und damit nicht über die Umrisslinie hinausragt.In the second embodiment with the ball joint, it will be ensured that the support plate can not perform any rotational movement and thus does not protrude beyond the outline.

Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist im Einzelnen Folgendes dargestellt:

Figur 1
zeigt in perspektivischer Ansicht eine Lasthebemaschine mit Stützen.
Figur 2
zeigt eine Stützeinrichtung, in einer Ansicht auf die Rückseite des Fahrzeuges.
Figur 3
zeigt die Stützeinrichtung gemäß Figur 2 in einer Ansicht auf eine Längsseite des Fahrzeuges.
Figur 4
zeigt eine Stützeinrichtung in perspektivischer Darstellung, gegenüber den Figuren 2 und 3 vergrößert.
The invention is explained in more detail with reference to the drawing. It details the following:
FIG. 1
shows in perspective view a lifting machine with supports.
FIG. 2
shows a support device, in a view of the rear of the vehicle.
FIG. 3
shows the support device according to FIG. 2 in a view on a longitudinal side of the vehicle.
FIG. 4
shows a support device in perspective view, with respect to the FIGS. 2 and 3 increased.

Die in Figur 1 gezeigte fahrbare Lasthebemaschine weist ein Fahrgestell 1 mit vier Rädern 2 auf. Der Aufbau der Maschine ist nicht weiter dargestellt. Er könnte jede beliebige Ausführungsform haben.In the FIG. 1 shown mobile lifting machine has a chassis 1 with four wheels 2. The structure of the machine is not shown. He could have any embodiment.

Entscheidend sind vier Stützeinrichtungen 3. Zwei dieser Stützeinrichtungen befinden sich im Bereich der Hinterräder, und zwei im Bereich der Vorderräder. Jede Stützeinrichtung umfasst eine Stütze 3.1 sowie ein Teleskoprohr 3.2, in dem die Stütze 3.1 auf- und abfahrbar ist.Decisive are four support devices 3. Two of these support devices are located in the area of the rear wheels, and two in the area of the front wheels. Each support device comprises a support 3.1 and a telescopic tube 3.2, in which the support 3.1 can be moved up and down.

Man erkennt ferner einen Stützteller 4. Zwischen dem unteren Ende der Stütze 3.1 und dem Stützteller 4 befindet sich ein Kardangelenk 5. Dieses weist zwei Gelenkzapfen 5.1 und 5.2 auf. Der eine Gelenkzapfen 5.1 befindet sich nahe bei der Umrisslinie. Er verläuft parallel zur Fahrtrichtung der fahrbaren Lasthebemaschine, oder parallel zu deren Längsmittelachse. Der zweite Gelenkzapfen 5.2 verläuft senkrecht zum ersten Gelenkzapfen 5.1.It also recognizes a support plate 4. Between the lower end of the support 3.1 and the support plate 4 is a universal joint 5. This has two pivot pin 5.1 and 5.2. The one pivot pin 5.1 is located near the outline. It runs parallel to the direction of travel of the mobile lifting machine, or parallel to its longitudinal central axis. The second pivot pin 5.2 runs perpendicular to the first pivot pin 5.1.

Das Kardangelenk 5 weist eine Lagerplatte 5.3 auf. Diese befindet sich nahe der Umrisslinie der fahrbaren Lasthebemaschine - hier nicht dargestellt. Der Kraftfluss tritt somit durch den Stützteller 4 hindurch, gelangt im Bereich der Lagerplatte 5.3 in das Kardangelenk 5, und von dort zur Stützeinrichtung 3.The universal joint 5 has a bearing plate 5.3. This is located near the contour of the mobile lifting machine - not shown here. The power flow thus passes through the support plate 4, passes in the region of the bearing plate 5.3 in the universal joint 5, and from there to the support device. 3

Die Lagerplatte 4 ragt nicht oder nur unwesentlich über die Lagerplatte 5.3 hinaus, und auf keinen Fall über die Umrisslinie. Auf der der Lagerplatte 5.3 gegenüberliegenden Seite hingegen kann und soll der Stützteller 4 nach innen ragen, das heißt von der Umrisslinie hinweg. Der Stützteller kann jegliche Kontur haben, beispielsweise rechteckig, gerundet, oval.The bearing plate 4 does not protrude or only insignificantly beyond the bearing plate 5.3 out, and in no case over the outline. On the opposite side of the bearing plate 5.3, however, the support plate 4 can and should protrude inwards, that is to say from the outline. The backing pad can have any contour, for example rectangular, rounded, oval.

Das Wesen der Erfindung lässt sich wie folgt zusammenfassen:

  • der Stützteller ist im Arbeitszustand derart angeordnet, dass er bis zur Umrisslinie reicht, aber nicht darüber hinausragt
  • der Stützkraftfluss findet in jenem Bereich des Stütztellers statt, der sich nahe der Umrisslinie befindet
  • der Stützkraftfluss wird sodann von der Umrisslinie hinweg und zur Längsmittelachse des Fahrzeuges hingeleitet (erste Umlenkung)
  • der Stützkraftfluss wird sodann in die Stützeinrichtung eingeleitet (zweite Umlenkung)
The essence of the invention can be summarized as follows:
  • the support plate is arranged in the working state such that it extends to the outline, but does not protrude beyond it
  • the support force flow takes place in that area of the support plate which is close to the contour line
  • the support force flow is then passed away from the outline and to the longitudinal central axis of the vehicle (first deflection)
  • the support force flow is then introduced into the support device (second deflection)
