Abstract

A scissor-type lifting table comprises scissor members (16, 18), which cross one another in the respective centre area, are pivotable towards one another, support a table plate (12) and are each connected firmly, but pivotably, at one end to the floor on one hand and to the underside of the table plate on the other hand, and a drive for the mutual pivoting of the scissor members for lifting or lowering the table plate. At the other end, the scissor members bear in a displaceable manner against the floor and the underside of the table plate. The drive comprises a rotatable spindle (30) essentially running through the pivot axis (20) of the scissor members (16, 18). The spindle (30) is in each case rotatably mounted, but in an axially fixed manner, in a sleeve (32) at one end at one of the lateral scissor angles and accommodates a spindle nut (34) in the opposite end area. The sleeve (32) and the spindle nut (34) are each connected to the two scissor members (16, 18) via two guide links (36, 38; 40, 42) pivotable on either side. <IMAGE>

Description

Die Erfindung betrifft einen Scherenhubtisch mit einander im jeweiligen Mittelbereich kreuzenden, gegeneinander schwenkbaren, eine Tischplatte tragenden Scherengliedern, die jeweils an einem Ende fest, jedoch schwenkbar mit dem Boden einerseits und der Unterseite der Tischplatte andererseits verbunden sind und am anderen Ende verschiebbar gegen den Boden und die Unterseite der Tischplatte anliegen, und mit einem Antrieb zum gegenseitigen Schwenken der Scherenglieder im Sinne einer Anhebung oder Absenkung der Tischplatte, der eine drehbare, im wesentlichen durch die Schwenk-Achse der Scherenglieder laufende Spindel umfaßt, die durch einen an einem Ende der Spindel befestigten Motor drehbar ist und wenigstens eine bei Drehung der Spindel in deren Längsrichtung verfahrbare Spindelmutter aufnimmt.The invention relates to a scissor-type lifting table with scissor members which cross each other in the respective central region, can be pivoted against one another and carry a table top, each of which is fixed at one end but is pivotally connected to the bottom on the one hand and the underside of the table top on the other hand and is displaceable at the other end against the floor and rest against the underside of the table top, and with a drive for pivoting the scissor members relative to one another in the sense of raising or lowering the table top, which comprises a rotatable spindle which essentially runs through the pivot axis of the scissor members and which is fastened by one end of the spindle Motor is rotatable and receives at least one spindle nut which can be moved in the longitudinal direction when the spindle rotates.

Scherenhubtische werden in der Praxis überwiegend mit Hilfe von Hydraulikzylindern angehoben oder abgesenkt. Dies stellt für den Normalfall eine robuste und relativ kostengünstige Lösung dar, mit der hohe Kräfte aufgebracht werden können. Hydraulikzylinder sind jedoch in einigen Fällen als Antrieb nicht geeignet. Zum einen setzen sie einen vollständigen Hydraulikkreis zur Betätigung voraus, der an ein vorhandenes Hydrauliknetz oder sogar an eine eigene Hydraulikpumpe angeschlossen sein muß. Zum anderen bereitet das genaue Positionieren des Tisches in vorgegebener Höhe Schwierigkeiten. Bei den häufig anzuhebenden großen Lasten addiert sich eine stets vorhandene Nachgiebigkeit in den einzelnen Organen des Hydrauliksystems zu einem beträchtlichen Gesamtwert. Der Tisch sinkt unter Last nach dem Einstellen einer gewünschten Höhe nach und nach leicht ab.In practice, scissor lift tables are mostly raised or lowered with the help of hydraulic cylinders. This is usually a robust and relatively inexpensive solution with which high forces can be applied. In some cases, however, hydraulic cylinders are not suitable as drives. On the one hand, they require a complete hydraulic circuit for actuation, which must be connected to an existing hydraulic network or even to a separate hydraulic pump. On the other hand, the exact positioning of the table at a given height is difficult. With the large loads to be lifted frequently, the resilience that is always present in the individual organs of the hydraulic system adds up to a considerable total value. The table gradually drops under load after setting a desired height.

Aus dem DE-GM 79 32 713 ist ein Scherenhubtisch mit Spindelantrieb bekannt. Diese Druckschrift befaßt sich mit Scherenhubtischen, die durch Hineinziehen von Rollen in die beiden seitlichen Scherenwinkel aufgerichtet werden sollen. Vor diesem Hintergrund werden verschiedene Antriebsformen, vor allem Seilzugantriebe erörtert. Ein Spindelantrieb wird als weitere Möglichkeit kurz erwähnt. Nähere Ausführungen zur Gestaltung des Spindelantriebs finden sich in der Druckschrift nicht.From DE-GM 79 32 713 a scissor lift table with spindle drive is known. This document deals with scissor lift tables which are to be erected by pulling rollers into the two side scissor angles. Against this background, different forms of drive, especially cable drives, are discussed. A spindle drive is briefly mentioned as another option. No further details on the design of the spindle drive can be found in the publication.

Die DE-AS 1 175 852 befaßt sich mit einer Scherenhebebühne, bei der ein Spindelmotor im Bereich des Gelenks der sich kreuzenden Scherenglieder fest aufgehängt ist. Die zugehörige Spindel erstreckt sich in einen der seitlichen Scherenwinkel, dessen angrenzende Scheren-Abschnitte eine Art von Nockenkurve bilden, auf der eine von der Spindel mit Hilfe einer Spindelmutter angezogene Rolle laufen kann. Auf diese Weise soll die Schere aufgerichtet werden.DE-AS 1 175 852 is concerned with a scissor lift at which a Spindle motor is firmly suspended in the area of the joint of the intersecting scissor links. The associated spindle extends into one of the lateral scissor angles, the adjacent scissor sections of which form a type of cam curve on which a roller which is tightened by the spindle with the aid of a spindle nut can run. This is how the scissors should be erected.

Das in den beiden vorgenannten Druckschriften verwendete Konstruktionsprinzip, bei dem Rollen in die seitlichen Scherenwinkel hineingezogen werden, dürfte hinsichtlich seiner Betriebssicherheit, Haltbarkeit und Zuverlässigkeit einige Bedenken hervorrufen. Die von den Rollen aufzunehmenden Kräfte sind erheblich, so daß die Lagerung und Aufhängung der Rollen äußerst massiv ausgebildet werden muß. Die Rollen stehen im übrigen mit den Scherengliedern im wesentlichen in einer linienförmigen Berührung, so daß hoher Verschleiß zu erwarten ist. Genau reproduzierbare Bewegungsabläufe dürften nicht zu erreichen sein.The design principle used in the two aforementioned documents, in which rollers are pulled into the side scissor angles, should raise some concerns with regard to its operational safety, durability and reliability. The forces to be absorbed by the rollers are considerable, so that the storage and suspension of the rollers must be made extremely solid. The rollers are essentially in line contact with the scissor members, so that high wear is to be expected. Precisely reproducible motion sequences should not be possible.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Scherenhubtisch der gattungsgemäßen Art zu schaffen, der sehr genau und dauerhaft in vorgegebener Höhe einstellbar ist.The invention is therefore based on the object of creating a scissor-type lifting table of the generic type which can be set very precisely and permanently at a predetermined height.

Diese Aufgabe wird bei einem Scherenhubtisch der oben genannten Art dadurch gelöst, daß der Motor über eine diesen tragende, das Spindel-Ende umgebende Hülse einerseits und die Spindelmutter andererseits über jeweils zwei beidseitig schwenkbare Lenker mit den beiden Scherengliedern verbunden ist.This object is achieved in a scissor lift table of the type mentioned above in that the motor is connected to the two scissor members via a sleeve which supports this and surrounds the spindle end on the one hand and the spindle nut on the other hand via two links which can be pivoted on both sides.

Der erfindungsgemäße Spindelantrieb benötigt lediglich eine Stromanschluß. Ein Hydrauliksystem ist somit entbehrlich, so daß der Scherenhubtisch auch in Fällen einsetzbar ist, in denen eine Hydrauliksystem nicht verfügbar ist oder nicht angewendet werden kann.The spindle drive according to the invention only requires a power connection. A hydraulic system is therefore unnecessary, so that the scissor lift table can also be used in cases in which a hydraulic system is not available or cannot be used.

Die Spindelmuttern und die Hülse werden durch Drehung der Spindel aneinander angenähert oder von einander entfernt. Bei der Annäherung drücken sie über die Lenker nach oben und unten gegen jeweils eines der Scherenglieder, so daß die Schere insgesamt aufgerichtet wird. An der ein Ende der Spindel aufnehmenden Hülse kann unmittelbar ein Antriebsmotor, in der Regel ein Elektromotor befestigt sein, dessen in der Hülse drehbare Ausgangswelle die Spindel bildet. Vorzugsweise bildet die Hülse mit einem koaxialen Flansch, an dem ein Flansch des Antriebmotors befestigt ist, eine zusammenhängende Einheit.The spindle nuts and the sleeve are brought closer to or apart from one another by rotating the spindle. When approaching, push the handlebars up and down against one of the scissor links, so that the scissors are erected as a whole. At the one end of the spindle receiving sleeve, a drive motor in the Usually an electric motor must be attached, the output shaft of which rotates in the sleeve forms the spindle. The sleeve preferably forms a coherent unit with a coaxial flange to which a flange of the drive motor is attached.

Weitere Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen.Further details of the invention emerge from the subclaims.

Der Scherenhubtisch gemäß Fig. 1 umfaßt eine Bodenplatte 10, die gegebenenfalls durch den Boden einer Halle oder auch durch den Boden einer Grube gebildet werden kann, und eine parallel zu dieser und oberhalb dieser verlaufende Tischplatte 12. Zwischen den beiden Platten 10,12 befindet sich eine Hubschere 14 mit einander kreuzenden Scherengliedern 16,18, die in einer waagerechten, senkrecht zur Zeichenebene verlaufenden Achse 20 schwenkbar mit einander verbunden sind. Gegebenenfalls können zwei oder mehrere in Bezug auf die Zeichenebene deckungsgleiche Hubscheren vorgesehen werden.1 comprises a base plate 10, which can optionally be formed by the floor of a hall or by the bottom of a pit, and a table top 12 running parallel to this and above it. Between the two plates 10, 12 there is a lifting shear 14 with intersecting scissor members 16, 18 which are pivotally connected to one another in a horizontal axis 20 running perpendicular to the plane of the drawing. If necessary, two or more lifting scissors congruent with respect to the drawing plane can be provided.

In der üblichen Weise ist eines der Scherenglieder 16 in einem Gelenk 22 fest an der Unterseite der Tischplatte 12 angebracht, während unterhalb des Gelenks 22 ein weiteres Gelenk 24 auf der Bodenplatte 10 befestigt ist, das schwenkbar das untere Ende des anderen Scherengliedes 18 aufnimmt. Dieses Scherenglied 18 stützt sich rechts oben in der Zeichnung über eine Rolle 26 verschiebbar an der Unterseite der Tischplatte 12 ab, während das andere Scherenglied 16 schräg nach rechts und nach unten verläuft und mit einer Rolle 28 auf der Bodenplatte 10 abrollt.In the usual way, one of the scissor members 16 is fixedly attached in a joint 22 to the underside of the table top 12, while below the joint 22 a further joint 24 is fastened on the base plate 10, which pivotally receives the lower end of the other scissor member 18. This scissor member 18 is supported on the top right in the drawing by a roller 26 from the underside of the table top 12, while the other scissor member 16 runs obliquely to the right and down and rolls with a roller 28 on the base plate 10.

Eine waagerechte Spindel 30 verläuft in waagerechter Richtung parallel zur Zeichenebene im wesentlichen senkrecht zur geometrischen Achslinie der Achse 20. Die Spindel 30 ist rechts in der Zeichnung in dem dort dargestellten Scherenwinkel in einer Hülse 32 drehbar, jedoch axial nicht verschiebbar gelagert, während sie links in der Zeichnung im dortigen Endbereich innerhalb des anderen Scherenwinkels mit Gewindeeingriff eine Spindelmutter 34 aufnimmt.A horizontal spindle 30 runs in the horizontal direction parallel to the plane of the drawing, essentially perpendicular to the geometrical axis line of the axis 20. The spindle 30 can be rotated on the right in the drawing in the scissor angle shown there in a sleeve 32, but is not axially displaceable while it is on the left in the drawing in the end area there receives a spindle nut 34 within the other scissor angle with thread engagement.

Die Spindelmutter 34 ist über an beiden Enden schwenkbare, von der Spindelmutter aus divergierende Lenker 36,38 mit den zugehörigen Abschnitten der beiden Scherenglieder 16,18 verbunden. In entsprechender Weise steht die Hülse 32 über spiegelbildlich angeordnete Lenker 40,42 mit den beiden anderen, rechts in der Zeichnung liegenden Abschnitten der Scherenglieder 16,18 schwenkbar in Verbindung. Es ist ersichtlich, daß die Lenker 36,38 bzw. 40,42 die Spindelmutter 34 und die Hülse 32 in Drehrichtung festhalten.The spindle nut 34 is connected to the associated sections of the two scissor members 16, 18 via links 36, 38 which can be pivoted at both ends and diverging from the spindle nut. In a corresponding manner, the sleeve 32 is pivotably connected to the two other sections of the scissor members 16, 18, which are arranged in mirror images, with the links 40, 42. It can be seen that the links 36, 38 and 40, 42 hold the spindle nut 34 and the sleeve 32 in the direction of rotation.

Daher führt eine Drehung der Spindel, die in der Hülse 32 frei drehbar ist und mit der Spindelmutter 34 im Gewindeeingriff steht, je nach Drehrichtung zu einer Annäherung oder Entfernung von Hülse und Spindelmutter.Therefore, a rotation of the spindle, which is freely rotatable in the sleeve 32 and is in threaded engagement with the spindle nut 34, leads, depending on the direction of rotation, to an approach or removal of the sleeve and the spindle nut.

Da bei der Annäherung von Hülse und Spindelmutter die Lenker 36 38 und 40,42 gegen die zugeordneten Abschnitte der Scherenglieder 16,18 gedrückt werden, richtet sich die Hubschere zunehmend auf, so daß die Tischplatte 12 angehoben wird. Die Absenkbewegung der Tischplatte tritt ein, wenn die Hülse 32 und die Spindelmutter 34 voneinander entfernt werden. Eine gewünschte Höhe kann sehr genau angefahren und gehalten werden.Since the handlebars 36 38 and 40, 42 are pressed against the assigned sections of the scissor members 16, 18 when the sleeve and spindle nut approach, the lifting scissors straighten up so that the table top 12 is raised. The lowering movement of the table top occurs when the sleeve 32 and the spindle nut 34 are removed from one another. A desired height can be approached and held very precisely.

In der dargestellten Ausführungsform ist die Hülse 32 mit einem koaxialen Flansch 44 verbunden, an den ein Flansch 46 eines Antriebsmotors 48 konzentrisch angeflanscht ist. Die Spindel bildet gewissermaßen die Ausgangswelle des Antriebsmotors 48.In the illustrated embodiment, the sleeve 32 is connected to a coaxial flange 44 to which a flange 46 of a drive motor 48 is flanged concentrically. To a certain extent, the spindle forms the output shaft of the drive motor 48.

Ein Scherenhubtisch gemäß Fig. 2 weist wiederum eine Bodenplatte 10, eine Tischplatte 12 und Scherenglieder 16,18 auf, die nur schematisch als Linien angedeutet sind. Die Spindel 30 verläuft in diesem Falle ebenfalls waagerecht und im wesentlichen durch die Achse 20, in der die Scherenglieder schwenkbar verbunden sind, ist jedoch kürzer als bei der ersten Ausführungsform. Die Hülse 32 und die Spindelmutter 34, die sich auf der Spindel 30 befinden, stimmen im Prinzip mit den entsprechenden Teilen der ersten Ausführungsform überein. Die Hülse 32, die die Spindel 30 ohne Gewindeeingriff frei drehbar umgibt, ist auf der rechten Seite in der Zeichnung über die Flansche 44 und 46 mit dem Antriebsmotor 48 fest verbunden.2 again has a base plate 10, a table plate 12 and scissor members 16, 18, which are only indicated schematically as lines. In this case, the spindle 30 also runs horizontally and essentially through the axis 20 in which the scissor members are pivotally connected, but is shorter than in the first embodiment. The sleeve 32 and the spindle nut 34, which are located on the spindle 30, correspond in principle to the corresponding parts of the first embodiment. The sleeve 32, which surrounds the spindle 30 in a freely rotatable manner without thread engagement, is firmly connected to the drive motor 48 on the right-hand side in the drawing via the flanges 44 and 46.

Von der Hülse 32 und der Spindelmutter 34 gehen jeweils zwei beidendig schwenkbare Lenker 50,52,54,56 aus. Die oberen Lenker 50,54 laufen zu dem schräg nach rechts oben aufsteigenden Abschnitt des Scherengliedes 18, während die unteren Lenker 52,56 zu dem schräg nach rechts absteigenden Abschnitt des anderen Scherengliedes 16 verlaufen. Die Verbindung zwischen den Lenkern und den Scherengliedern 16,18 kann bei jedem der Scherenglieder 16,18 in einer Achse 58,60 erfolgen, wie es in Fig. 2 gezeigt ist, jedoch auch in Achsen, die in einem mehr oder weniger großen Abstand liegen.Two sleeves 50, 52, 54, 56 extend from the sleeve 32 and the spindle nut 34. The upper links 50, 54 run to the section of the scissor link 18 that rises upward to the right, while the lower links 52, 56 run to the section of the other scissor link 16 that descends to the right. The connection between the links and the scissor members 16, 18 can take place in each of the scissor members 16, 18 in an axis 58, 60, as shown in FIG. 2, but also in axes which are at a more or less large distance .

Aus Fig. 2 geht unmittelbar hervor, daß beim Zusammenziehen der Spindelmutter 34 und der Hülse 32 durch Drehung der Spindel 30 die Achsen 58,60 und mit diesem die rechts in Fig. 2 liegenden Abschnitte der Scherenglieder 16,18 nach oben bzw. nach unten gedrückt werden. Die Tischplatte 12 wird also angehoben. Bei der gegenläufigen Drehung der Spindel 30, wenn also die Hülse 32 und die Spindelmutter 34 sich voneinander entfernen, wird die Tischplatte 12 abgesenkt.From Fig. 2 it is immediately apparent that when the spindle nut 34 and the sleeve 32 are pulled together by rotating the spindle 30, the axes 58, 60 and, with this, the sections of the scissor members 16, 18 on the right in FIG be pressed. The table top 12 is thus raised. When the spindle 30 rotates in the opposite direction, ie when the sleeve 32 and the spindle nut 34 move away from one another, the table top 12 is lowered.

Der wesentliche Unterschied zwischen den beiden Ausführungsformen der Figuren 1 und 2 besteht darin, daß sich die Spindel 30 bei Fig.1 in waagerechter Richtung gleichermaßen zu beiden Seiten der Achse 40 des Scheren kreuzes erstreckt, und daß die Lenker 36,38,40,42 innerhalb des linken bzw. rechten Winkels zwischen den Scherengliedern jeweils zu dem oberen und unteren Scherenglied-Abschnitt verlaufen, während sich in Fig. 2 der gesamte Antriebsmechanismus in einem, nämlich dem rechten Winkel zwischen den Scherengliedabschnitten befindet und der Hubmechanismus nur auf diese rechten Abschnitte einwirkt.The essential difference between the two embodiments of Figures 1 and 2 is that the spindle 30 in Fig.1 extends in the horizontal direction equally on both sides of the axis 40 of the scissors, and that the link 36,38,40,42 run within the left or right angle between the scissor links to the upper and lower scissor link sections, while in Fig. 2 the entire drive mechanism is in one, namely the right angle between the scissor link sections and the lifting mechanism acts only on these right sections .

Beide Ausführungsformen lassen sich dahingehend abwandeln, daß der Antriebsmotor 48 sowie die Positionen von Hülse 32 und Spindelmutter 34 in umgekehrter Orientierung angeordnet werden. Während dies bei Fig. 1 keinen wesentlichen Unterschied bedeutet, ergibt sich bei Fig. 2 eine besonders kompakte Ausführungsform, da der Antriebsmotor 48 im linken und der Antriebsmechanismus mit Spindel und Lenkern im rechten Winkel zwischen den Scherengliedern liegt.Both embodiments can be modified such that the drive motor 48 and the positions of the sleeve 32 and spindle nut 34 in reverse orientation. 1, there is a particularly compact embodiment in FIG. 2, since the drive motor 48 is in the left and the drive mechanism with spindle and handlebars is at a right angle between the scissor members.

Eine weitere Abwandlung ist bei beiden Ausführungsformen dahingehend möglich, daß die Spindel in senkrechter Richtung durch die Achse 20 des Scherenkreuzes verläuft. Dadurch wird jedoch der verfügbare Hub stark begrenzt, da der Antriebsmotor je nach Anordnung mit zunehmender Absenkung der Tischplatte gegen die Tischplatte oder die Bodenplatte stößt.A further modification is possible in both embodiments in that the spindle runs in a vertical direction through the axis 20 of the scissor cross. However, this greatly limits the available stroke, since the drive motor, depending on the arrangement, hits the table top or the base plate with increasing lowering of the table top.

Ein Scherenhubtisch gemäß Fig. 3 unterscheidet sich von dem Tisch gemäß Fig. 1 nur dadurch, daß die Lenker 36, 38 bzw. 40, 42 einander kreuzen, d. h. von den Scherengliedern 16, 18 aus zur jeweils gegenüberliegenden Seite der Hülse 32 bzw. der Spindelmutter 34 geführt sind. Bei dieser Anordnung ergibt sich ein günstigerer Winkel zwischen den Lenkern 36, 38, 40, 42 und den Scherengliedern 16, 18 zu Beginn der Hubbewegung.A scissor lift table according to FIG. 3 differs from the table according to FIG. 1 only in that the links 36, 38 and 40, 42 cross each other, i. H. are guided from the scissor members 16, 18 to the opposite side of the sleeve 32 or the spindle nut 34. With this arrangement there is a more favorable angle between the links 36, 38, 40, 42 and the scissor members 16, 18 at the beginning of the lifting movement.
