Description

Die gegenständliche Erfindung betrifft eine Hebeeinrichtung mit einer Anzahl von Führungssäulen, an denen ein Hubschlitten in einer Heberichtung geführt verfahrbar angeordnet ist, und am Hubschlitten Flaschenzüge, bestehend aus einem Zugmittel und einer Anzahl von Umlenkrollen, zum Heben des Hubschlittens angreifen.The subject invention relates to a lifting device with a number of guide columns on which a lifting guided guided in a lifting direction movable, and attack on the lifting pulleys, consisting of a traction means and a number of pulleys, for lifting the lifting.

In Fertigungsanlagen, wie z.B. in der Fahrzeugfertigung, werden oftmals Hebeeinrichtungen benötigt, mit denen bestimmte Bauteile angehoben werden, z.B. um mit anderen Bauteilen verbunden zu werden, z.B. beim Fügen von Antriebsstrang und Karosserie in der Fahrzeugfertigung. Dabei ist der Raum oberhalbe der Hebeeinrichtung freizuhalten. Zum Einsatz kommen daher häufig Scherenhubtische oder Säulenhebebühnen. Bei Scherenhubtischen sind zwar hohe Lasten und hohe Hubgeschwindigkeiten möglich, allerdings hat die mögliche Hubhöhe direkten Einfluss auf die Dimensionen des Hubtisches. Große Hubhöhen bewirken dabei immer große Längen, sowie große eingefahrene Höhen des Scherenhubtisches, was Auswirkungen auf den erforderlichen Einbauraum hat. Außerdem benötigt ein Scherenhubtisch zum Anheben aus der eingefahrenen Position in der Regel auch höhere Leistungen, als im weiteren Hub benötigt werden, womit der Antrieb auch auf größere Leistung ausgelegt werden muss. Auch Säulenhebebühnen ermöglichen hohe Lasten, allerdings je nach Antrieb nur eingeschränkte Geschwindigkeiten. Säulenhebebühnen in der Form von Seilhubbühnen haben in der Regel den Nachteil, dass der Raum oberhalb des Hubtisches aufgrund der benötigten Haken, Traversen, Seile, Rollen, Seiltrommeln, etc. nicht frei ist, und Seilhubbühnen daher für viele Anwendungen nicht einsetzbar sind. Eine Seilhubbühne ist z.B. aus der JP 2002 128 211 A2 oder der JP 2000 344 307 A bekannt.In manufacturing plants, such as in vehicle manufacturing, often lifting devices are required with which certain components are raised, for example, to be connected to other components, such as the joining of powertrain and body in vehicle production. The space above the lifting device is to be kept clear. Scissor lift tables or column lifts are therefore often used. Although high loads and high lifting speeds are possible with scissor lift tables, the possible lifting height has a direct influence on the dimensions of the lifting table. Large lifting heights always cause great lengths, as well as large retracted heights of the scissor lift, which has an effect on the required installation space. In addition, a scissor lift for lifting from the retracted position usually also requires higher power levels than are needed in the wider hub, so the drive must be designed for greater performance. Post lifts also allow high loads, but only limited speeds depending on the drive. Post lifts in the form of Seilhubbühnen usually have the disadvantage that the space above the lifting table due to the required hooks, trusses, ropes, rollers, rope drums, etc. is not free, and Seilhubbühnen therefore can not be used for many applications. A Seilhubbühne is eg from the JP 2002 128 211 A2 or the JP 2000 344 307 A known.

Beiden Ausführungen ist ein komplexer Aufbau mit der Notwendigkeit genauer Bearbeitungstoleranzen gemein, was in hohen Herstellungs- und Wartungskosten mündet.Both versions have a complex structure with the need for accurate machining tolerances in common, resulting in high manufacturing and maintenance costs.

Aus der DE 20 2005 015 899 U1 ist eine Seil-Hebebühne bekannt, bei der an einem Hubboden vier Zugmittel angreifen, die von einer gemeinsamen Antriebseinheit angetrieben werden, um eine synchrone Bewegung der Zugmittel sicherzustellen. Zwei Zugmittel sind unterhalb des Hubbodens auf die der Antriebseinheit gegenüberliegenden Seite der Hebebühne geführt, womit der Raum oberhalb des Hubbodens frei bleiben kann.From the DE 20 2005 015 899 U1 a rope hoist is known in which attack on a lifting floor four traction means which are driven by a common drive unit to ensure a synchronous movement of the traction means. Two traction means are guided below the lifting floor on the side opposite the drive unit side of the lift, whereby the space above the lifting floor can remain free.

Außerdem bieten solche Hebeeinrichtungen von Haus aus keine freie Beweglichkeit des Hubtisches, was aber insbesondere zum genauen Positionieren zweier Bauteile zueinander wichtig ist. Das kann nur durch zusätzliche konstruktive Maßnahmen realisiert werden, was die Komplexität und Kosten solcher Hebeeinrichtungen weiter erhöht.In addition, such lifting devices do not offer free mobility of the lifting table, but this is particularly important for the exact positioning of two components to each other. This can only be realized by additional design measures, which further increases the complexity and cost of such lifting devices.

Weiters wird von solchen Hebeeirichtungen auch ein hohes Maß an Ausfall- und Fehlersicherheit gefordert, um den Fertigungsprozess nicht unterbrechen zu müssen, was zu hohen Folgekosten führen kann.Furthermore, such hoisting arrangements also require a high degree of failure and failure safety in order not to interrupt the production process, which can lead to high follow-up costs.

US 2005/087116 A1 offenbart eine Hebeeinrichtung gemäß dem Oberbegriff des Anspruchs 1. US 2005/087116 A1 discloses a lifting device according to the preamble of claim 1.

Es ist daher eine Aufgabe der gegenständlichen Erfindung eine Hebeeinrichtung anzugeben, die die obigen Nachteile behebt, die einfach und kostengünstig aufgebaut ist und die darüber hinaus auch ausfall- und fehlersicher betrieben werden kann.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, indem in der Hebeeinrichtung zwei Flaschenzuggruppen mit jeweils zwei Flaschenzügen vorgesehen sind, wobei jede Flaschenzuggruppe jeweils von einer gemeinsamen Antriebseinheit angetrieben ist und die Flaschenzüge einer Flaschenzuggruppe an zwei gegenüberliegenden Seiten und an diagonal gegenüberliegenden Punkten am Hubschlitten angreifen und je ein Zugmittel einer Flaschenzuggruppe unterhalb des Hubschlittens auf die gegenüberliegende Seite des Hubschlittens geführt ist. Durch die Führung des Zugmittels unterhalb des Hubschlittens, kann der Bauraum oberhalb des Hubschlittens frei von Komponenten der Hebeeinrichtung gehalten werden und steht daher für Fertigungsabläufe zur Verfügung. Indem beide Flaschenzüge einer Flaschenzuggruppe von einer gemeinsamen Antriebseinheit angetrieben werden, kann auch ohne aufwendige und schwierige Synchronisation der Flaschenzüge sichergestellt werden, dass immer beide Zugmittel einer Flaschenzuggruppe auf Zug sind und damit eine Last tragen. Dadurch kann ein einzelner Flaschenzug auf geringere Lasten ausgelegt werden. Durch den diagonal gegenüberliegenden Angriffspunkt der Flaschenzüge jeder Flaschenzuggruppe kann bei Ausfall einer Flaschenzuggruppe ein Verkanten des Hubschlittens verhindert werden, was die Fehler- aus Ausfallssicherheit erhöht.
Wenn der Hubschlitten zwei Rahmenteile aufweist, die an den Führungssäulen geführt verfahrbar angeordnet sind, wobei die Rahmenteile durch einen schwimmend gelagerten Schwimmrahmen verbunden sind, kann die freie Positionierbarkeit eines Bauteils am Hubschlittens auf einfache Weise realisiert werden. Dadurch kann ein Bauteil am Hubschlitten sehr einfach relativ zu einem anderen Bauteil verschoben werden, was den Fertigungsprozess, insbesondere einen Füge- oder Montageprozess, erheblich erleichtert, bzw. was in gewissen Fertigungsanlagen auch gefordert sein kann.
Die gegenständliche Erfindung wird nachfolgend unter Bezugnahme auf die Figuren 1 bis 3 die schematisch und nicht einschränkend, vorteilhafte Ausgestaltungen der Erfindung zeigen, näher erläutert. Dabei zeigt

  • Fig.1 und 2 jeweils eine schematische Darstellung einer erfindungsgemäßen Hebeeinrichtung in unterschiedlichen Ansichten und
  • Fig.3 einen alternativen Angriff eines Zugmittels am Hubschlitten.
It is therefore an object of the subject invention to provide a lifting device which overcomes the above disadvantages, which is simple and inexpensive and which can also be operated fail-safe and fail-safe beyond.
This object is achieved in that two pulley groups are each provided with two pulleys in the lifting device, each pulley is driven in each case by a common drive unit and the pulleys a pulley group attack on two opposite sides and at diagonally opposite points on the lifting and one each Traction means a pulley group is guided below the lifting slide on the opposite side of the lifting. By the guidance of the traction means below the lifting carriage, the space above the lifting carriage can be kept free of components of the lifting device and is therefore available for production processes. By both pulleys a pulley group driven by a common drive unit, it can be ensured even without complex and difficult synchronization of the pulleys, that always both traction means a pulley group are on train and thus carry a load. This allows a single pulley to be designed for lower loads. Due to the diagonally opposite point of attack of the pulleys each pulley group can be prevented in case of failure of a pulley group tilting of the lifting, which increases the error from reliability.
If the lifting carriage has two frame parts, which are arranged movably guided on the guide columns, wherein the frame parts are connected by a floating floating frame, the free positioning of a component on the lifting carriage can be realized in a simple manner. As a result, a component on the lifting carriage can be displaced very simply relative to another component, which considerably simplifies the production process, in particular a joining or assembly process, or which may also be required in certain production systems.
The subject invention will be described below with reference to the FIGS. 1 to 3 the schematic and non-limiting, advantageous embodiments of the invention, explained in more detail. It shows
  • Fig.1 and 2 in each case a schematic representation of a lifting device according to the invention in different views and
  • Figure 3 an alternative attack a traction device on the lifting.

In der erfindungsgemäßen Hebeeinrichtung 1 gemäß Fig.1 und 2 sind vier senkrechte Hubsäulen 2 ortsfest in der Hebeeinrichtung 1, z.B. an einem Hallenboden 4, angeordnet. An den Hubsäulen 2 sind an einander zugewandten Seitenflächen Führungsschienen 5 angeordnet. Zwischen den Hubsäulen 2 ist ein Hubschlitten 6 angeordnet, der hier aus zwei, an den Führungsschienen 5 geführten Rahmenteilen 7 besteht. Die Rahmenteile 7 weisen dazu z.B. jeweils zwei Führungsrollenpaare 8 auf, die die Führungsschienen 5 umgreifen. Die Führung des Hubschlittens 6 an den Führungssäulen 2 kann aber natürlich konstruktiv auch anders gelöst sein. Der Hubschlitten 6 ist daher in Hubrichtung (hier in vertikaler Richtung) gegenüber den Hubsäulen 2 verfahrbar angeordnet. Die Rahmenteile 7 des Hubschlittens 6 sind hier durch einen Schwimmrahmen 9 verbunden, wobei der Schwimmrahmen 9 bezüglich der Rahmenteile 7 bzw. bzgl. der Hubsäulen 2 schwimmend gelagert sein kann, z.B. wie im gezeigten Ausführungsbeispiel auf Kugelrollen 17 gelagert. Damit lässt sich der Schwimmrahmen 9 zur Positionierung eines darauf befindlichen Bauteils innerhalb bestimmter Grenzen normal auf die Hubrichtung, hier also z.B. in einer Horizontalebene, verschieben. Wenn es der jeweilige Fertigungsprozess erfordert, kann die Bewegung des Schwimmrahmens 9 während des gesamten Hubes des Hubschlittens 6, oder für eine definierte Hubstrecke, mechanisch verriegelt werden.In the lifting device 1 according to the invention Fig.1 and 2 are four vertical lifting columns 2 fixed in the lifting device 1, for example, on a hall floor 4, arranged. At the lifting columns 2 guide rails 5 are arranged on mutually facing side surfaces. Between the lifting columns 2, a lifting 6 is arranged, which here consists of two, guided on the guide rails 5 frame parts 7. For example, the frame parts 7 each have two guide roller pairs 8, which surround the guide rails 5. Of course, the guidance of the lifting carriage 6 on the guide columns 2 can also be solved differently in terms of design. The lifting 6 is therefore arranged in the lifting direction (here in the vertical direction) relative to the lifting columns 2 movable. The frame parts 7 of the lifting carriage 6 are here connected by a floating frame 9, wherein the floating frame 9 with respect to the frame parts 7 and respect. The lifting columns 2 may be floatingly mounted, for example, as shown in the embodiment mounted on ball rollers 17. This allows the floating frame 9 for positioning a component thereon within certain limits normal to the stroke, in this example, in a horizontal plane move. If required by the particular manufacturing process, the movement of the floating frame 9 can be mechanically locked during the entire stroke of the lifting carriage 6, or for a defined stroke.

Der Hubschlitten 6 wird im dargestellten Ausführungsbeispiel mittels vier Flaschenzügen 20, 21, 22, 23 gehoben. Jeder Flaschenzug 20, 21, 22, 23 besteht aus einem Zugmittel 10a, 10b, 11a, 11b, wie z.B. ein Seil, eine Kette, etc., und einer Anzahl von Umlenkrollen 12, hier drei Umlenkrollen 23 pro Zugmittel. Jeweils zwei Flaschenzüge 20, 21 und 22, 23 werden zu einer Flaschenzuggruppe zusammengefasst und jeweils gemeinsam von einer gemeinsamen Antriebseinheit 16, z.B. bestehend aus einer von einem Elektromotor 14 (oder Getriebemotor) angetriebenen Seiltrommel 15, angetrieben. Jeder Flaschenzug 20, 21, 22, 23 greift am Hubschlitten 6, bzw. wie hier an den Rahmenteilen 7, an. Je nach Ausgestaltung des Flaschenzuges 20, 21, 22, 23 erfolgt die Verbindung mit dem Hubschlitten 6 über eine Umlenkrolle 12 (wie in Fig.1), oder direkt über das Zugmittel 10a, 10b, 11a, 11 b (wie in Fig.3), was aber nicht erfindungswesentlich ist.The lifting 6 is lifted in the illustrated embodiment by means of four pulleys 20, 21, 22, 23. Each pulley 20, 21, 22, 23 consists of a traction means 10a, 10b, 11a, 11b, such as a rope, a chain, etc., and a number of pulleys 12, here three pulleys 23 per traction device. In each case two pulleys 20, 21 and 22, 23 are combined to form a pulley group and in each case jointly by a common drive unit 16, for example consisting of one of an electric motor 14 (or geared motor) driven cable drum 15, driven. Each pulley 20, 21, 22, 23 engages the lifting slide 6, or as here on the frame parts 7, on. Depending on the configuration of the pulley 20, 21, 22, 23, the connection with the lifting slide 6 via a guide roller 12 (as in Fig.1 ), or directly via the traction means 10a, 10b, 11a, 11b (as in Figure 3 ), which is not essential to the invention.

Die Flaschenzüge 20, 21 und 22, 23 einer Flaschenzuggruppe greifen an zwei gegenüberliegenden Seiten und an diagonal gegenüberliegenden Punkten am Hubschlitten 6 an (Fig. 2). Ein Seil 10b, 11 b eines Flaschenzuges 21, 23 jeder Flaschenzuggruppe wird dabei unter dem Hubrahmen 6 auf die andere Seite der Hebeeinrichtung 1 geführt. Damit wird der Raum oberhalb des Hubschlittens 6 frei von Zugmittel 10a, 10b, 11 a, 11 b, Umlenkrollen 12 oder anderen Teilen eines Flaschenzuges gehalten.The pulleys 20, 21 and 22, 23 of a pulley group engage on two opposite sides and at diagonally opposite points on the lifting carriage 6 ( Fig. 2 ). A cable 10b, 11b of a pulley 21, 23 each pulley group is guided under the lifting frame 6 on the other side of the lifting device 1. This is the room above the lifting 6 free of traction means 10 a, 10 b, 11 a, 11 b, pulleys 12 or other parts of a pulley.

Dadurch, dass die Flaschenzüge 20, 21 und 22, 23 jeder Flaschenzuggruppe einen eigenständigen Antrieb haben, kann der Ausfall einer Flaschenzuggruppe oder eines Flaschenzuges 20, 21, 22, 23 einfach kompensiert werden. Jeder Antrieb kann dabei so ausgelegt sein, dass er alleine den Hubschlitten 6 samt Last mit der geforderten Geschwindigkeit heben kann. Es kann aber auch vorgesehen sein, dass bei Ausfall einer Flaschenzuggruppe oder eines Flaschenzuges 20, 21, 22, 23 nur eine eingeschränkte Hubgeschwindigkeit erreicht wird. Indem die Flaschenzüge diagonal gegenüber an Hubschlitten 6 abgreifen, wirkt bei Ausfall einer Flaschenzuggruppe oder eines Flaschenzuges 20, 21, 22, 23 nur ein begrenztes Kippmoment auf die Führung des Hubschlittens 6 an den Hubsäulen 2, womit einem eventuellen Blockieren des Hubschlittens 6 vorgebeugt werden kann. Auf diese Weise wird ein hohes Maß an Ausfalls- und Fehlersicherheit erzielt.The fact that the pulleys 20, 21 and 22, 23 each pulley group have a separate drive, the failure of a pulley group or a pulley 20, 21, 22, 23 can be easily compensated. Each drive can be designed so that it alone lift the lifting 6 together with the load at the required speed. However, it can also be provided that in case of failure of a pulley group or a pulley 20, 21, 22, 23 only a limited lifting speed is achieved. By tipping the pulleys diagonally opposite to lifting 6, acts in case of failure of a pulley group or a pulley 20, 21, 22, 23 only a limited overturning moment on the leadership of the lifting 6 to the lifting columns 2, whereby a possible blocking of the lifting carriage 6 can be prevented , In this way, a high degree of failure and failure safety is achieved.

Die erfindungsgemäße Hebeeinrichtung 1 könnte wie folgt eingesetzt werden. Ein Bauteil 30, z.B. ein Antriebsstrang eines Fahrzeuges, wird auf einem Bauteilträger 31 auf einer Fördereinrichtung 32, wie z.B. ein Förderband, ein Skid-System, oder Ähnliches, zur Hebeeinrichtung 1 transportiert und am Hubschlitten 6 abgelegt. Der Hubschlitten 6 mit dem Bauteil 30 wird nun bis zu einer vorgesehenen Fügeposition mit einem zweiten Bauteil (hier nicht dargestellt), z.B. eine Fahrzeugkarosserie, angehoben. Es kann auch vorgesehen sein, dass der Bauteil 30 nur bis knapp unterhalb der Fügeposition angehoben wird und der restliche Hub manuell unter gleichzeitiger Positionierung des Bauteils zum zweiten Bauteil vorgenommen wird.The lifting device 1 according to the invention could be used as follows. A component 30, e.g. a drive train of a vehicle, is mounted on a component carrier 31 on a conveyor 32, such as a conveyor. a conveyor belt, a skid system, or the like, transported to the lifting device 1 and placed on the lifting 6. The lifting carriage 6 with the component 30 will now be up to an intended joining position with a second component (not shown here), e.g. a vehicle body, raised. It can also be provided that the component 30 is raised only just below the joining position and the rest of the stroke is carried out manually with simultaneous positioning of the component to the second component.

Weiters kann vorgesehen sein, dass die Anbindungen 13 der Zugmittel 10a, 10b, 11a, 11 b am Hubschlitten 6 bzw. in der Hebeeinrichtung 1 an sich bekannte Einrichtungen zum Überwachen auf Störfälle, wie z.B. Schlaffseil, Seilriss und Überlast, enthalten, wie in Fig.1 angedeutet. Furthermore, it can be provided that the connections 13 of the traction means 10a, 10b, 11a, 11b on the lifting carriage 6 or in the lifting device 1 comprise per se known devices for monitoring for incidents such as slack rope, cable break and overload, as in Fig.1 indicated.
