Description

Radfreie Hubvorrichtung, für eine Kraftfahrzeughebebühne mit Fahrschienen oder eine überfahrgrube.Wheel-free lifting device, for a motor vehicle lift with rails or a drive-over pit.

Die Erfindung betrifft eine radfreie Hubvorrichtung, für eine Kraftfahrzeughebebühne mit Fahrschienen oder eine überfahrgrube, wobei auf jeder Fahrschiene eine solche Hubvorrichtung angeordnet ist.The invention relates to a wheel-free lifting device for a motor vehicle lifting platform with rails or a drive-over pit, such a lifting device being arranged on each rail.

Es ist eine radfreie Hubvorrichtung für eine Kraftfahrzeughebebühne bekannt, die auf der Fahrschiene angeordnet ist. Dabei bildet jedoch die Fahrschiene der Kraftfahrzeugbühne und die radfreie Hubvorrichtung eine bauliche Einheit, mit der Folge, daß die Fahrschiene eine spezielle Ausbildung erfahren muß, damit die Hubvorrichtung nicht zu weit übersteht.A wheel-free lifting device for a motor vehicle lifting platform is known, which is arranged on the running rail. However, the running rail of the motor vehicle platform and the wheel-free lifting device form a structural unit, with the result that the running rail must undergo special training so that the lifting device does not protrude too far.

Dies bedingt für denjenigen Benutzer, der bereits eine Kraftfahrzeughebebühne besitzt, einen zusätzlichen Kostenaufwand, da er nur die Kraftfahrzeughebebühne zusammen mit der Hubvorrichtung erwerben kann.This requires an additional cost for the user who already has a motor vehicle lift, since he can only purchase the motor vehicle lift together with the lifting device.

Der Erfindung liegt daher die Aufgabe zugrunde, eine radfreie Hubvorrichtung zu schaffen, die so ausgebildet ist, daß sie für bestehende Kraftfahrzeughebebühnen verwendbar ist und die die geringst möglichen Abmessungen aufweist, damit sie leicht überfahrbar und dabei standfest ist.The invention is therefore based on the object of providing a wheel-free lifting device which is designed such that it can be used for existing motor vehicle lifts and which has the smallest possible dimensions so that it can be easily driven over and is stable.

Dies wird erfindungegemäß dadurch erreicht, daß die Hubvorrichtung als gesonderte nachrüstbars Aufsatzhebebühne ausgebildet ist, die als Scherengestell mit Luftbalg ausgebildet ist, wobei deren Trag- und Standplatte zugleich die Verschlußplatten für den Luftbalg sind.This is achieved according to the invention in that the lifting device is designed as a separate retrofittable lifting platform which is designed as a scissor-type frame with an air bellows, the support and base plates of which are at the same time the closure plates for the air bellows.

Durch diese Ausbildung der Hubvorrichtung wird die Bauhöhe der AufsatzhebebUhne sehr klein, so daß sie leicht überfahrbar ist und deshalb nachträglich angebracht werden kann.This design of the lifting device makes the height of the top lifting platform very small, so that it can be easily driven over and can therefore be retrofitted.

Eine besonders vorteilhafte Ausführungsform besteht darin, daB der Luftbalg in Längsrichtung der Fahrschienen und seitlich zum Scherengestell, angeordnet ist. Durch diese besondere Anordnung des Luftbalgs seitlich zum Scherengestell wird die Aufsatzhebebühne nicht breiter als die Fahrschiene, was die Standsicherheit der Aufsatzhebebühne verbessert.A particularly advantageous embodiment consists in the air bellows being arranged in the longitudinal direction of the travel rails and laterally to the scissor-type frame. This special arrangement of the air bellows to the side of the scissor-type frame means that the top lift does not become wider than the travel rail, which improves the stability of the top lift.

Nach einer besonders vorteilhaften Ausführungsform ist die Tragplatte in Längsrichtung zu beiden Seiten stufenförmig ausgebildet. Dadurch wird die Tragplatte insgesamt kürzer im Vergleich zu einer mit Keilansätzen versehenen Tragplatte. Gleichwohl wird aber die überfahrbarkeit der Tragplatte nicht verschlechtert, weil wegen der Trägheit des Fahrzeuges die ctufenförmige Ausbildung leichter überfahrbar ist als eine keilförmige Ausbildung, bei der die Fahrfläche kontinuierlich ansteigt.According to a particularly advantageous embodiment, the support plate is stepped in the longitudinal direction on both sides. As a result, the support plate is overall shorter compared to a support plate provided with wedge approaches. Nevertheless, the ability to drive over the support plate is not impaired because, due to the inertia of the vehicle, the stepped design is easier to drive over than a wedge-shaped design in which the driving surface increases continuously.

Hierdurch wird außerdem erreicht, daß die'Distanzklötze aus Gummi, die zwischen der Tragplatte und dem Holm des Fahrzeuges angeordnet werden, jeweils bis an das Ende der Tragplatte gebracht werden können. Bei den sonst üblichen Ansatzkeilen an der Tragplatte ist dieses nicht möglich, da die Distanzstücke dann auf diesen schrägen Ansatzkeilen liegen würden.This also ensures that the 'distance blocks made of rubber, which are arranged between the support plate and the spar of the vehicle, can each be brought to the end of the support plate. This is not possible with the usual shoulder wedges on the support plate, since the spacers would then lie on these oblique shoulder wedges.

Weiterhin ist an der Tragplatte an mindestens einer Breitseite eine Auslegerplatte vorgesehen, die vorzugsweise teleskopartig ausziehbar ist, wobei die Auslegerplatte etwa halb so dick ist wie die Tragplatte. Hierdurch wird erreicht, daß auch Fahrzeuge mit großem Achsabstand sicher auf der Aufsatzhebebühne gehalten werden können, da die Länge der Tragplatte dem Achsabstand angepaßt werden kann.Furthermore, a cantilever plate is provided on at least one broad side of the support plate, which is preferably telescopically extendable, the cantilever plate being approximately half as thick as the support plate. This ensures that vehicles with a large center distance can be held securely on the top lift, since the length of the support plate can be adapted to the center distance.

Nach einer besonders vorteilhaften Ausführungsform ist an der Tragplatte ein Anschlag zur Begrenzung der Ausziehlänge der Auslegerplatte vorgesehen, um hierdurch zu verhindern, daß das Moment auf die Teleskoparme, das sich aus dem Gewicht des Kraftfahrzeuges und der Ausziehlänge ergibt, zu groß wird. Die Teleskoparme sind hierbei an ihrem einen Ende in entsprechenden Führungen der Tragplatte gelagert, und an ihrem anderen Ende an der Auslegerplatte befestigt.According to a particularly advantageous embodiment, a stop is provided on the support plate to limit the extension length of the extension plate, in order to prevent the torque on the telescopic arms, which results from the weight of the motor vehicle and the extension length, from becoming too great. The telescopic arms are in this case mounted at one end in corresponding guides of the support plate and fastened at the other end to the extension plate.

In Fig. 1 ist mit 1 eine Vier-Säulen-Hebebühne dargestellt, auf deren Fahrschienen 2 jeweils eine Aufsatzhebebühne 3 lösbar als gesonderte Einheit befestigt ist.In Fig. 1, 1 is a four-post lift, on the rails 2 of which an attachable lift 3 is detachably attached as a separate unit.

Die Aufsatzhebebühne 3 besteht aus einer Standplatte 4 und einer Tragplatte 5; durch Schrauben 4a ist die Standplatte, und damit die Aufsatzhebebühne, auf der Fahrschiene 2 lösbar befestigt (Fig. 2).The top lift 3 consists of a base plate 4 and a support plate 5; The base plate, and thus the top lift, is detachably fastened to the running rail 2 by screws 4a (FIG. 2).

Zwischen Tragplatte 5 und Standplatte 4 ist das Scherengestell 11 angeordnet; außerhalb des Scherengestells 11 und zwar in Längsrichtung der Fahrschiene 2 seitlich zum Scherengestellbefindet sich der Luftbalg 12, der die eigentliche Hubbewegung der Tragplatte 5 bewirkt. Das Scherengestell 11 besteht aus zwei parallelen Scherenpaaren lla, 11b, die miteinander durch eine Stützstrebe 13 verbunden sind. Jede Schere eines solchen Scherenpaares lla, llb ist an einem Ende fest mit der Trag- bzw. Standplatte verbunden, und an ihrem anderen Ende beweglich auf der Trag- bzw. Standplatte angeordnet, wie dies an sich bekannt ist.The scissor-type frame 11 is arranged between the support plate 5 and the base plate 4; Outside of the scissor-type frame 11, namely in the longitudinal direction of the travel rail 2, to the side of the scissor-type frame, there is the air bellows 12, which causes the actual lifting movement of the support plate 5. The scissor frame 11 consists of two parallel pairs of scissors 11a, 11b, which are connected to one another by a support strut 13. Each pair of scissors of such a pair of scissors 11a, 11b is fixedly connected to the support or base plate at one end, and is movably arranged on the support or base plate at its other end, as is known per se.

Die Tragplatte 5 einerseits und die Standplatte 4 andererseits bilden gleichzeitig die Verschlußplatten für den Luftbalg 12.The support plate 5 on the one hand and the base plate 4 on the other hand simultaneously form the closure plates for the air bellows 12.

Durch diese Maßnahme können gesonderte Verschlußplatten am oberen und unteren Ende des Luftbalges 12 entfallen, so daß sich hierdurch eine weitere Minimierung der Bauhöhe ergibt (Fig. 4).This measure makes it possible to dispense with separate closure plates at the upper and lower ends of the air bellows 12, so that the overall height is further minimized (FIG. 4).

Die Trageplatte 5 weist zwei in Längsrichtung angeordnete Hohlprofile 6, 6a auf, in denen jeweils ein als Tragarm 7, 7a ausgebildetes Profil in Längsrichtung verschiebbar angeordnet ist. An ihrem Ende sind die beiden Tragarme durch die Auslegerplatte 8 miteinander verbunden. Hierdurch wird die Möglichkeit geschaffen, die Aufsatzhebebühne zu verlängern (Fig. 3 gestrichelte Darstellung), um so auch Fahrzeuge mit großem Achsabstand heben zu können, ohne daß die Gefahr besteht, daß diese in Längsrichtung abkippen.The support plate 5 has two hollow profiles 6, 6a arranged in the longitudinal direction, in each of which a profile designed as a support arm 7, 7a is arranged to be displaceable in the longitudinal direction. At their end, the two support arms are connected to one another by the extension plate 8. This creates the possibility to extend the top lift (Fig. 3 dashed representation), so as to be able to lift vehicles with a large center distance without the risk that they tip over in the longitudinal direction.

Zur Begrenzung der Ausziehlänge ist an den Tragarmen 7, 7a eine Anachlagleiste 9 vorgesehen, die an ihrem einen Ende eine Nase 9a aufweist; korrespondierend hierzu besitzt die Tragplatte 5 einen Anschlag 9b. Die Begrenzung der Ausziehlänge erfolgt dadurch, daß die Nase 9a gegen den an der Tragplatte 5 angeordneten Anschlag 9b läuft, der im Querschnitt ein U-Profil ist. Der Abstand zwischen den beiden horizontalen Schenkeln des U-Profils ist hierbei so bemessen, daß die Nase 9a der Anschlagleiste 9, nicht durch das U-Profil gezogen werden kann. Hierdurch ist in jedem Fall sichergestellt, daß die Auslegerplatte 8 nur soweit ausgezogen werden kann, daß das Moment auf die Tragarme 7, 7a nicht so groB wird, daß diese abknicken.To limit the pull-out length, an attachment bar 9 is provided on the support arms 7, 7a and has a nose 9a at one end; corresponding to this, the support plate 5 has a stop 9b. The extension length is limited in that the nose 9a runs against the stop 9b arranged on the support plate 5, which is U-shaped in cross section. The distance between the two horizontal legs of the U-profile is dimensioned so that the nose 9a of the stop bar 9 can not be pulled through the U-profile. This ensures in any case that the extension plate 8 can only be pulled out to such an extent that the moment on the support arms 7, 7a does not become so great that they bend.

Die Tragplatte 5 ist an der einen Seite stufenförmig ausgebildet (Fig. 2 Pfeil 5a).The support plate 5 is stepped on one side (Fig. 2 arrow 5a).

Diese Stufenform ersetzt die an sich bekannten Keilansätze, die die Baulänge der Aufsatzhebebühne nicht unwesentlich verlängern. Die Stufenform verkürzt die Baulänge, verschlechtert aber nicht die überfahrbarkeit.This step shape replaces the wedge attachments, which are known per se and which significantly extend the overall length of the overhead lift. The step shape shortens the overall length, but does not impair the ability to drive over.

Die an der anderen Seite der Tragplatte 5 angeordnete Auslegerplatte 8 ist etwa halb so dick wie die Tragplatte 5, so daß sich auch an dieser Seite eine stufenförmige Ausbildung ergibt.The cantilever plate 8 arranged on the other side of the support plate 5 is approximately half as thick as the support plate 5, so that there is also a stepped design on this side.

Der Verzicht auf Keilansätze bringt darüber hinaus den Vorteil mit sich, daß die Distanzstücke 10, die sich zwischen Fahrzeugholm und Tragplatte 5 bzw. Auslegerplatte 8 befinden, an jede beliebige Stelle auf die Trag- bzw. Auslegerplatte horizontal gesetzt werden können, so daß immer der günstigste Kraftangriffspunkt zum Heben des Fahrzeugs gewahlt werden kann.The elimination of wedge approaches also has the advantage that the spacers 10, which are located between the vehicle spar and support plate 5 or extension plate 8, can be placed horizontally at any point on the support or extension plate, so that always the cheapest force application point for lifting the vehicle can be selected.

Die Stützstrebe 13 bildet zusammen mit dem in Längsrichtung verfahrbaren Stufenkeil 14 eine Verriegelung, die verhindert, daß das Scherengestell beim Druckabfall im Luftbalg zusammenklappt.The support strut 13 forms, together with the longitudinally movable step wedge 14, a lock which prevents the scissor frame from collapsing when the pressure in the air bellows drops.

Der Stufenkeil ist mittels eines Kolbenzylinderantriebes 15 in Längsrichtung zur Aufsatzhebebühne verschiebbar angeordnet. Der Weg des Kolbens 15a ist hierbei direkt abhängig von der Hubhöhe des Luftbalges 12, so daß jeweils bei Erreichen einer bestimmten Hubhöhe, eine entsprechende Stufe 14a des Stufenkeiles 14 die Stützstrebe ergreift.The step wedge is arranged so as to be displaceable in the longitudinal direction of the top lift by means of a piston cylinder drive 15. The path of the piston 15a is directly dependent on the lifting height of the air bellows 12, so that each time a certain lifting height is reached, a corresponding step 14a of the step wedge 14 grips the support strut.

Die Ausrichtung der Aufsatzhebebühne auf der Fahrschiene erfolgt so, daß sich der Luftbalg unter dem Schwerpunkt des schwersten zu hebenden Fahrzeuges befindet, wobei die Lage des Fahrzeugschwerpunktes in Bezug auf die Fahrschienen durch die auf den Fahrschienen angeordneten Spurvermessungsteller bestimmt wird. Beim Anheben befindet sich das schwerste zu hebende Fahrzeug somit in der Waage,so daß die Tragarme 7, 7a der Auslegerplatte 8 nicht übermäßig beansprucht werden. Der Schwerpunkt von kleineren und damit leichteren Fahrzeugen befindet sich somit nicht unbedingt über dem Luftbalg 12, so daß in diesem Fall die Tragarme etwas mehr belastet werden. Dies ist aber nicht von Bedeutung, da diese Fahrzeuge, wie bereits ausgeführt, leichter sind.The top lift is aligned on the running rail so that the air bellows is under the center of gravity of the heaviest vehicle to be lifted, the position of the center of gravity in relation to the running rails being determined by the wheel alignment adjusters arranged on the running rails. When lifting, the heaviest vehicle to be lifted is thus in the balance, so that the support arms 7, 7a of the extension plate 8 are not excessively stressed. The center of gravity of smaller and thus lighter vehicles is therefore not necessarily above the air bellows 12, so that in this case the support arms are loaded a little more. However, this is not important since, as already stated, these vehicles are lighter.
