Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft einen Scherenhubtisch nach den Oberbegriffen der Ansprüche 1 und 4.The invention relates to a scissor lift according to the preambles of claims 1 and 4.

STAND DER TECHNIKSTATE OF THE ART

Ein entsprechender Scherenhubtisch ist aus DE 100 01 910 B4 bekannt. Zum Anheben des Tisches wird dort zwischen den gekreuzten, um die Scherenachse schwenkbaren Scherenblättern ein Hubwagen mittels eines Zugbandes in Richtung auf die Scherenachse gezogen. Dabei läuft der Hubwagen über an den Scherenblättern lösbar oder verstellbar befestigte Hubkurven. Die Hubkurven sorgen dafür, dass die Hublast, die von dem Zugband aufgebracht wird, über den Hubvorgang in vorteilhafter Weise verteilt werden kann. Dies erleichtert insbesondere das Anfahren im vollständig abgesenkten Zustand des Scherenhubtisches.A corresponding scissor lift is off DE 100 01 910 B4 known. To lift the table there is a lifting truck pulled by a drawstring in the direction of the scissors axis there between the crossed scissor blades which are pivotable about the scissors axis. The lift truck runs on the scissor blades releasably or adjustably mounted lifting curves. The lifting curves ensure that the lifting load, which is applied by the drawstring, can be distributed over the lifting operation in an advantageous manner. This facilitates in particular the startup in the fully lowered state of the scissor lift.

Dieser Aufbau hat sich in der Vergangenheit durchaus bewährt. Allerdings sind aufgrund des eingeschränkten Raumangebots die Variationsmöglichkeiten der verwendeten Hubkurven eingeschränkt.This structure has proven itself in the past quite well. However, due to the limited space available, the possibilities of variation of the stroke curves used are limited.

Weiter ist dieser Aufbau in gewisser Weise nicht hinreichend wartungsfreundlich, da die im Innern der Schere in Richtung der Scherenachse verlaufenden Zugbänder den Zugang zu einigen Bereichen des Scherenhubtisches im Wartungsfall erschweren und ggf. erst entfernt werden müssen, um eine Wartung vornehmen zu können.Further, this structure is not sufficiently easy to maintain in some ways, since the running in the interior of the scissors in the direction of the scissors axis drawstrings make access to some areas of the scissor lift in the maintenance difficult and possibly only need to be removed to make a maintenance.

In der FR-1.026.383 A ist ein Scherenhubtisch offenbart, bei dem eine Hubkurve an der Basisvorrichtung befestigt ist. Um den Scherenhubtisch anzuheben, wird ein Hubwagen zwischen diese Hubkurve und ein Scherenblatt gezogen, wobei sich der Hubwagen an der Randkontur des Scherenblattes abstützt. Dabei kommt es jedoch im Laufe der Hubbewegung zu ungünstigen Winkelverhältnissen zwischen den Kräften, die der Hubwagen auf Scherenblatt und Hubkurve ausübt. Die Folge ist, dass der Antrieb über ein Zugmittel entsprechend hohe Kräfte auf den Zugwagen ausüben muss, um ein Anheben des Scherenhubtisches zu ermöglichen.In the FR-1.026.383 A a scissor lift is disclosed in which a lift curve is attached to the base device. To raise the scissor lift, a lift truck is drawn between this lift curve and a scissor blade, wherein the lift truck is supported on the edge contour of the scissor blade. However, in the course of the lifting movement, unfavorable angular relationships occur between the forces exerted by the lifting carriage on the scissor blade and the lifting cam. The consequence is that the drive must exert a correspondingly high forces on the towing vehicle via a traction device in order to enable the scissor lift to be raised.

DIE ERFINDUNGTHE INVENTION

Aufgabe der vorliegenden Erfindung ist es daher, einen eingangs genannten Scherenhubtisch dahingehend zu verbessern, dass die erwähnten Nachteile nicht auftreten.Object of the present invention is therefore to improve a Scherenhubtisch mentioned above to the effect that the mentioned disadvantages do not occur.

Gelöst wird diese Aufgabe durch einen Scherenhubtisch mit den Merkmalen der Ansprüche 1 und 4. Vorteilhafte Ausführungsformen finden sich in den Unteransprüchen.This object is achieved by a scissor lift with the features of claims 1 and 4. Advantageous embodiments can be found in the dependent claims.

Erfindungsgemäß ist die Hubkurve an der Basisvorrichtung befestigt, so dass der Hubwagen zwischen der Hubkurve und der ersten Scherenblattanordnung geführt wird. Dazu ist insbesondere eine Linearführung vorgesehen, die mit der Basisvorrichtung zugewandten Abschnitten der ersten Scherenblattanordnung verbunden ist. Weiter ist die Linearführung zwischen der Schenkelachse und der die erste Scherenblattanordnung und die Basisvorrichtung verbindenden Anlenkeinrichtung vorgesehen.According to the invention, the lifting cam is fastened to the base device, so that the lifting carriage is guided between the lifting cam and the first shear blade arrangement. For this purpose, in particular a linear guide is provided, which is connected to the base device facing portions of the first scissor blade assembly. Further, the linear guide between the leg axis and the first scissor blade assembly and the base device connecting the connecting device is provided.

Die Anlenkeinrichtung kann z.B. ein die Scherenblattanordnung mit der Basisvorrichtung verbindender Gelenkbolzen sein.The hinging device may e.g. be a hinge pin connecting the shear blade assembly to the base device.

Bevorzugt ist das Zugmittel auf einer Trommel aufwickelbar. Die Trommel kann durch einen Antrieb, insbesondere einen Antriebsmotor, betätigt werden und ist bevorzugt an der Basisvorrichtung auf der der Hubkurve gegenüber liegenden Seite der die erste Scherenblattanordnung und die Basisvorrichtung verbindenden Anlenkeinrichtung (1b) vorgesehen.Preferably, the traction means can be wound on a drum. The drum can be actuated by a drive, in particular a drive motor, and is preferably provided on the base device on the side opposite the lift cam of the articulation device (1b) connecting the first slide blade arrangement and the base device.

Dadurch ergeben sich zahlreiche Vorteile. Zum einen steht auf der Basisvorrichtung für die Ausbildung der Hubkurve ein größerer Raum zur Verfügung. Weiter verläuft das Zugmittel so in etwa parallel zur Basisvorrichtung und reicht nicht mehr in das Innere des Scherenhubtisches hinein und auch nicht über die Scherenachse hinaus, so dass Behinderungen bei der Wartung weitgehend vermieden werden. Zudem können an der Basisvorrichtung bei dieser Zugmittelführung eine Mehrzahl Umlenkeinrichtungen, insbesondere Umlenkrollen, für das Zugmittel installiert werden, die nicht im Hubbereich des Scherenhubtisches liegen und das Anheben bzw. Absenken des Scherenhubtisches somit nicht behindern. Durch das Vorsehen einer Mehrzahl Umlenkrollen kann gegenüber der bekannten Lösung ein Flaschenzugprinzip realisiert werden, damit lässt sich der Antrieb zum Aufwickeln des Zugmittels ggf. kleiner auslegen, was wiederum Kosten einsparen kann. Dazu kann insbesondere vorgesehen sein, dass das Zugmittel über eine erste, an der zweiten Scherenblattanordnung angebrachte Umlenkeinrichtung und eine zwischen der Anlenkeinrichtung und der Trommel angeordnete zweite Umlenkeinrichtung zum Hubwagen geführt ist.This results in numerous advantages. Firstly, a larger space is available on the base device for the formation of the lift curve. Further, the traction means is approximately parallel to the base device and no longer extends into the interior of the scissor lift and also not beyond the scissors axis, so that obstructions during maintenance are largely avoided. In addition, a plurality of deflection devices, in particular deflection rollers, for the traction means can be installed on the base device in this Zugmittelführung that are not in the stroke range of Scherenhubtisches and thus not hinder the raising or lowering of the scissor lift. By providing a plurality of pulleys over the known solution, a pulley principle can be realized, so that the drive for winding the traction means can possibly be designed smaller, which in turn can save costs. For this purpose, it can be provided, in particular, that the traction means is guided to the lift truck via a first deflecting device attached to the second trailing blade arrangement and a second deflecting device arranged between the articulation device and the drum.

KURZBESCHREIBUNG DER ZEICHNUNGSABBILDUNGENBRIEF DESCRIPTION OF THE DRAWING FIGURES

Die Erfindung wird nun anhand der Zeichnungsfigur näher erläutert, welche ein Ausführungsbeispiel der Erfindung zeigt.The invention will now be explained in more detail with reference to the drawing figure, which shows an embodiment of the invention.

BESTER WEG ZUR AUSFÜHRUNG DER ERFINDUNGBEST MODE FOR CARRYING OUT THE INVENTION

Der Scherenhubtisch wird gebildet durch eine Tragvorrichtung 10, eine auf dem Boden oder einer Aufstellfläche anzuordnende Basisvorrichtung 11 und eine zwischen Tragvorrichtung 10 zur Aufnahme des zu hebenden Gegenstandes und Bäsisvorrichtung 11 angeordnete Schere. Die Schere wird durch gekreuzte und um eine Scherenachse 6 gegeneinander verschwenkbare Scherenblattanordnungen, nämlich eine erste Scherenblattanordnung 1 und eine zweite Scherenblattanordnung 2, gebildet. Jede Scherenblattanordnung 1, 2 weist bevorzugt zwei oder mehr parallel zueinander angeordnete Scherenblätter auf, von denen in der gezeigten Seitenansicht lediglich jeweils eines dargestellt ist.The scissor lift is formed by a support device 10, a base device 11 to be arranged on the floor or a footprint, and a pair of scissors arranged between support 10 for receiving the article to be lifted and the laundry device 11. The scissors are formed by crossed and about a scissors axis 6 against each other pivotable scissor blade arrangements, namely a first scissors blade assembly 1 and a second scissor blade assembly 2. Each scissors blade arrangement 1, 2 preferably has two or more scissor blades arranged parallel to one another, of which only one is shown in the side view shown.

Die Scherenblätter einer Scherenblattanordnung 1, 2 sind fest miteinander, z.B. durch nicht gezeigte Quertraversen, verbunden, insbesondere verschweißt.The scissor blades of a scissors blade assembly 1, 2 are fixed together, e.g. by cross-ties, not shown, connected, in particular welded.

Wie in der Figur zu sehen, ist die Schere mit der zweiten Scherenblattanordnung 2 an der Tragvorrichtung 10 angelenkt. Das Anlenken erfolgt hier mit einem Gelenkbolzen 2a. Das gegenüberliegende Ende 2b der zweiten Scherenblattanordnung ist in einer Führung 11a in der Basisvorrichtung 11 verschieblich geführt. Ähnlich ist das obere Ende 1a der ersten Scherenblattanordnung 1 in einer Führung 10a in der Tragvorrichtung 10 geführt, während das untere, dem Ende 1a gegenüberliegende Ende 1b der ersten Scherenblattanordnung 1 an der Basisvorrichtung 11 angelenkt ist. Auch hier kann wieder ein Anlenkbolzen vorgesehen sein, der mit den Scherenblättern verbunden ist.As can be seen in the figure, the pair of scissors with the second scissor blade assembly 2 is hinged to the support device 10. The articulation takes place here with a hinge pin 2a. The opposite end 2b of the second scissor blade assembly is slidably guided in a guide 11a in the base device 11. Similarly, the upper end 1a of the first scissors blade assembly 1 is guided in a guide 10a in the support 10, while the lower end 1a opposite the end 1a of the first scissor blade assembly 1 is hinged to the base 11. Again, a pivot pin may be provided, which is connected to the scissor blades.

Betätigt wird die Schere durch einen Hubwagen 3, welcher durch einen (nicht dargestellten) die Trommel 5 antreibenden Antrieb bewegt wird. Das auf die Trommel 5 aufwickelbare und mit dem Hubwagen 3 verbundene Zugmittel 4, das bevorzugt wenigstens ein Band umfasst, wird beim Aufwickeln auf die Trommel 5 gezogen und bewegt den Hubwagen in Richtung A zur Trommel 5 hin. Dabei verfährt der Hubwagen 3 in Richtung der Anlenkachse bei 1b über die Hubkurve 8 und entlang der Linearführung 7 und verschwenkt dadurch die Scherenblattanordnung 1 in Richtung P1.The scissors are actuated by a lift truck 3, which by a (not shown) the drum 5 driving drive is moved. The drawable on the drum 5 and connected to the truck 3 traction means 4, which preferably comprises at least one band is pulled when winding on the drum 5 and moves the truck in the direction A to the drum 5 out. Here, the lift truck 3 moves in the direction of the pivot axis at 1b on the lifting cam 8 and along the linear guide 7 and thereby pivots the scissors blade assembly 1 in the direction of P1.

Dadurch wird ebenfalls die Scherenblattanordnung 2 aufgrund der Kopplung an der Scherenachse 6 verschwenkt und die Tragvorrichtung 10 wird angehoben, wobei die Enden 1a und 2b in den betreffenden Führungen 10a bzw. 11a in Richtung A verschoben werden.Thereby, the scissors blade assembly 2 is also pivoted due to the coupling to the scissor shaft 6 and the support device 10 is raised, the ends are moved 1a and 2b in the respective guides 10a and 11a in the direction A.

Zum Absenken des Tisches bzw. der Tragvorrichtung 10 wird das Zugmittel 4 von der Trommel abgewickelt. Die Schwerkraft des Tisches bewirkt dann, dass der Hubwagen zwischen der Scherenblattanordnung 1 und der Hubkurve 8 so weit in Richtung B bewegt wird, wie es das Zugmittel 4 zulässt. Durch das Abwickeln des Zugmittels 4 von der Trommel wird der Hubwagen 3 also im Wesentlichen in Richtung B bewegt, wodurch die oberen Enden 2a und 1a der beiden gekoppelten Scherenblattanordnungen 1, 2 zur Basisvorrichtung 11 hin verschwenkt werden, wie exemplarisch durch Pfeil P2 für die zweite Scherenblattanordnung 2 angedeutet. Die beiden Enden 1a und 2b bewegen sich dann entsprechend in den jeweiligen Führungen 10a, 11a in Richtung B. Dadurch wird der Tisch abgesenkt.To lower the table or the support device 10, the traction means 4 is unwound from the drum. The gravity of the table then causes the pallet truck between the scissor blade assembly 1 and the lifting cam 8 is moved as far in the direction B, as it allows the traction means 4. By unwinding of the traction means 4 of the drum of the truck 3 is thus moved substantially in the direction B, whereby the upper ends 2 a and 1 a of the two coupled scissor blade assemblies 1, 2 are pivoted to the base device 11, as exemplified by arrow P2 for the second Scherenblattanordnung 2 indicated. The two ends 1a and 2b then move correspondingly in the respective guides 10a, 11a in the direction B. As a result, the table is lowered.

Vorteilhafterweise wird das Zugmittel 4 von der Trommel 5 über eine erste Umlenkrolle 9b, die im Bereich des unteren, der Basisvorrichtung zugewandten Endes 2b der zweiten Scherenblattanordnung 2 an derselben angebracht ist, und mindestens eine weitere Umlenkrolle 9a zum Hubwagen 3 geführt. Die zweite Umlenkrolle 9a ist fest mit der Basisvorrichtung 11 verbunden und bevorzugt zwischen der Trommel 5 und der Anlenkachse, um die die erste Schenkelanordnung 1 verschwenkbar an der Basisvorrichtung 11 angelenkt ist, bzw. dem unteren, der Basisvorrichtung 11 zugewandten Ende 1b der ersten Scherenblattanordnung 1 angeordnet.Advantageously, the traction means 4 of the drum 5 via a first guide roller 9b, which is mounted in the region of the lower, the base device facing end 2b of the second shear blade assembly 2 at the same, and at least one further guide roller 9a to the truck 3. The second guide roller 9a is fixedly connected to the base device 11 and preferably between the drum 5 and the An articulation axis, about which the first leg arrangement 1 is pivotably articulated to the base device 11, or the lower, the base device 11 facing the end of the first scissor blade arrangement 1 1 arranged.

Auf diese Weise lässt sich ein Flaschenzugprinzip mit loser und fester Rolle realisieren und reduziert so die Anforderungen an die Dimensionierung des Aggregats zum Antrieb der Trommel 5.In this way, a pulley principle can be realized with loose and fixed role, thus reducing the requirements for the dimensioning of the unit to drive the drum. 5
