Abstract

A twin-column stationary lift (1) for raising motorized vehicles, each column (2) being equipped with a slide (4) which can be adjusted for height, with two carrying arms (8) which can be adjusted for length and capable of being moved apart, in order to support the motorized vehicle (10). In order to facilitate work on the floor of the body of a motorized vehicle, this invention proposes that the pairs of pivoting arms (8) be linked to the slides (4), each by an adjustment device (5, 6), both adjustment devices being able to pivot around a common horizontal axis (A). In addition, retaining devices (12, 13) are provided to maintain the vehicle in place in a reliable manner. This invention also makes it possible to transform existing twin-column lifts at no great expenses in the manner described in the invention.

Description

Die Erfindung bezieht sich auf eine stationäre Zweisäulen-Hebebühne zum Anheben eines Kraftfahrzeuges gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a stationary two-column lifting platform for lifting a motor vehicle according to the preamble of patent claim 1.

Eine solche Zweisäulen-Hebebühne ist aus der AU-B-470 742 bekannt. Diese Hebebühne weist zwei stationäre Säulen auf, an denen jeweils höhenverstellbare Schlitten mit je zwei spreizbaren Tragarmen angeordnet sind. Die Tragarme weisen an ihren Enden Stützkörper, z. B. Stützplatten auf, die das anzuhebende Kraftfahrzeug jeweils an einem Punkt unterstützen. Die Schlitten für die Tragarmpaare sind synchron längs der Säulen höhenverstellbar, so daß das Kraftfahrzeug in die gewünschte Arbeitshöhe angehoben werden kann, wonach der gesamte Karosserieboden des Kraftfahrzeuges frei zugänglich ist.Such a two-column lift is known from AU-B-470 742. This lift has two stationary columns, on each of which height-adjustable carriages with two spreadable support arms are arranged. The support arms have support bodies at their ends, e.g. B. support plates that support the motor vehicle to be lifted at one point. The carriages for the pairs of support arms are synchronously height-adjustable along the columns, so that the motor vehicle can be raised to the desired working height, after which the entire body floor of the motor vehicle is freely accessible.

Obwohl derartige stationäre Zweisäulen-Hebebühnen einen hohen Bedienungskomfort aufweisen und Arbeiten an der Unterseite des Kraftfahrzeuges erleichtern, verbleibt der Nachteil, daß die Arbeiten oft in angestrengter Körper-, insbesondere Kopfhaltung durchgeführt werden müssen.Although stationary two-post lifts of this type have a high level of operating comfort and make work on the underside of the motor vehicle easier, the disadvantage remains that the work often has to be carried out in a strenuous posture, in particular the head.

Aus dem DE-GM-7 117 555 ist eine Vorrichtung zum Heben und Wenden eines Kraftfahrzeuges bekannt. Diese Vorrichtung weist zwei fahrbare Standgerüste auf, die gegen den Bug und das Heck des Kraftfahrzeuges geschoben werden, so daß das Kraftfahrzeug in der Mitte der Standgerüste steht. Jedes Standgerüst weist einen höhenverstellbaren, quer zur Längsachse des Kraftfahrzeuges verlaufenden Träger auf, der zusätzlich um eine Schwenkachse parallel zur Mittellängsachse des Kraftfahrzeuges verschwenkt werden kann.A device for lifting and turning a motor vehicle is known from DE-GM-7 117 555. This device has two mobile stands, which are pushed against the bow and rear of the motor vehicle, so that the motor vehicle is in the middle of the stand. Each stand has a height-adjustable support which runs transversely to the longitudinal axis of the motor vehicle and which can additionally be pivoted about a pivot axis parallel to the central longitudinal axis of the motor vehicle.

Die freien Enden der Schwenkarme beider Standgerüste werden mit Längsträgern verbunden, die in der Länge einstellbar sind. Das Kraftfahrzeug wird mit einem Wagenheber angehoben. Anschließend wird ein Rad nach dem anderen abgenommen und die jeweils frei werdende Nabe mit auf den Längsträgern verstellbar angebrachten Halterungen befestigt. Wenn alle vier Naben befestigt sind, kann das Kraftfahrzeug durch einen Spindeltrieb oder Motoren an den Standgerüsten angehoben werden. Ist das Kraftfahrzeug ausreichend hoch gehoben, so können die Schwenkarme z. B. mit einem Schneckenradgetriebe um die erwähnte Achse verschwenkt werden, so daß das Kraftfahrzueg nach links oder rechts im seine Mittellängsachse gedreht wird. Dadurch wird der Karosserieboden des Kraftfahrzeuges für Arbeiten frei zugänglich.The free ends of the swivel arms of both stand scaffolds are connected to side members that are adjustable in length. The motor vehicle is raised with a jack. Then one wheel after the other is removed and the hub that is released in each case is fastened with brackets that are adjustably mounted on the longitudinal members. When all four hubs are attached, the motor vehicle can be lifted by a spindle drive or motors on the stand scaffolding. If the motor vehicle is raised sufficiently high, the swivel arms can, for. B. be pivoted with a worm gear around the axis mentioned, so that the motor vehicle is rotated to the left or right in its central longitudinal axis. As a result, the body floor of the motor vehicle is freely accessible for work.

Diese bekannte Vorrichtung ist relativ aufwendig zu bedienen. Die Arbeiten zum Aufsetzen des Kraftfahrzeuges sind umständlich. Die Vorrichtung benötigt außerdem speziell gefertigte Standgerüste, die in der Regel in einer Werkstatt nicht vorhanden sind.This known device is relatively complex to use. The work to put on the motor vehicle is cumbersome. The device also requires specially manufactured stand scaffolds, which are usually not available in a workshop.

Eine weitere Sonderkonstruktion ist aus der DE-A-1 556 381 bekannt. Auch diese Sonderkonstruktion ist keine stationäre Zweisäulen-Hebebühne der in Rede stehenden Art. Die bekannte Hebebühne weist zwei Standgestelle auf, an denen längs Mittelsäulen jeweils ein in der Höhe verfahrbarer Schlitten befestigt ist. An beiden Schlitten sind Querträger vorgesehen, wobei die Querträger der beiden Schlitten durch Streben miteinander verbunden werden. Auf die Querträger und die Verbindungsstreben kann noch eine Plattform aufgesetzt werden, so daß auf diese Plattform auch ein Kraftfahrzeug gefahren werden kann. Die Querträger sind jeweils an ihrem Schlitten über ein Schwenkgetriebe befestigt, so daß die Winkelstellung der Querträger und damit auch der gesamten Plattform verändert werden kann. Damit könnte auch, wie in der Verwendungsskizze 7 angedeutet, ein auf der Plattform der Hebebühne angeordnetes Kraftfahrzeug nach entsprechender Befestigung geschwenkt werden. Eine Vorrichtung zum sicheren Halten des Kraftfahrzeuges ist in dieser Patentanmeldung jedoch nicht angegeben.Another special construction is known from DE-A-1 556 381. This special construction is also not a stationary two-column lift of the type in question. The known lift has two stand frames, to each of which a carriage which is movable in height is fastened along central columns. Crossbeams are provided on both carriages, the crossbeams of the two carriages being connected to one another by struts. A platform can also be placed on the cross members and the connecting struts, so that a motor vehicle can also be driven on this platform. The cross members are each attached to their slide via a swivel gear so that the angular position of the cross members and thus the entire platform can be changed. This could also, as indicated in the use sketch 7, pivot a motor vehicle arranged on the platform of the lifting platform after appropriate fastening. A device for securely holding the motor vehicle is not specified in this patent application.

Ein wesentlicher Nachteil dieser aufwendig konstruierten Hebebühne liegt auch darin, daß der Unterboden des Kraftfahrzeuges zumindest nicht an den Stellen bearbeitet werden kann, an denen die Verbindungsstreben zwischen den Querträgern verlaufen. Da hier gegebenenfalls mehrere solche Verbintdungsstreben vorgesehen sein sollen, bleibt ein erheblicher Anteil des Kraftfahrzeugbodens für Reparaturarbeiten unzugänglich. Wenn zusätzlich noch eine Plattform vorgesehen ist, so kann diese Hebebühne für den vorgesehenen Zweck garnicht eingesetzt werden.A major disadvantage of this elaborately designed lifting platform is that the underbody of the motor vehicle can at least not be worked on at the points where the connecting struts between the cross members run. Since several such connection struts should be provided here, a considerable proportion of the vehicle floor remains inaccessible for repair work. If a platform is also provided, this lift cannot be used for the intended purpose.

Der Erfindung liegt die Aufgabe zugrunde, eine stationäre Zweisäulen-Hebebühne der im Oberbegriff des Patentanspruches 1 angegebene Art so auszugestalten, daß bei einer einfachen Konstruktion insbesondere Über-Kopf-Arbeiten vermieden werden, ohne daß dadurch die Bedienungsfreundlichkeit derartiger Hebebühnen gemindert wird.The invention has for its object to design a stationary two-column lift of the type specified in the preamble of claim 1 in such a way that overhead work can be avoided with a simple construction, without thereby reducing the user-friendliness of such lifts.

Der Erfindung liegt die Aufgabe zugrunde, eine stationäre Zweisäulen-Hebebühne der in Rede stehenden Art so auszugestalten, daß insbesondere Überkopfarbeiten vermieden werden, ohne daß dadurch die Bedienungsfreundlichkeit derartiger Hebebühnen gemindert wird.The invention is based on the object of designing a stationary two-column lift of the type in question in such a way that overhead work in particular is avoided without thereby reducing the user-friendliness of such lift.

Diese Aufgabe ist gemäß der Erfindung durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of patent claim 1.

Demgemäß braucht eine übliche stationäre Zweisäulen-Hebebühne nur geringfügig modifiziert zu werden, um ein Kraftfahrzeug in eine Höhe zu bringen und in dieser um eine Querachse zu schwenken, so daß dann das Arbeitsfeld praktisch direkt in Blickrichtung vor einem Mechaniker liegt. Mit der vorgeschlagenen Zwei Säulen-Hebebühen wird das Kraftfahrzeug in üblicher Weise angehoben, d. h. die an den Schlitten befestigten Tragarme werden unter den Karosserieboden des Kraftfahrzeuges geschwenkt und anschließend die Schlitten in der Höhe verstellt, bis sie an dem Boden des Kraftfahrzeuges anliegen. Ein separater Wagenheber zum Anheben des Kraftfahrzeuges ist nicht notwendig. Anschließend wird die Halteeinrichtung mit einem Fixpunkt am Kraftfahrzeug verbunden. Eine sichere Lösung ist es, nach Anheben des Kraftfahrzeuges zwei Räder zu entfernen und dann auf die frei stehenden Gewindezapfen der Bremstrommein jeweils einen Lochflansch aufzusetzen und zu befestigen, der über den Verbindungsarm mit dem Anlenkpunkt der Schwenkarme an den Schlitten verbunden ist.Accordingly, a conventional stationary two-post lift only needs to be modified slightly in order to bring a motor vehicle to a height and to pivot it about a transverse axis, so that the working field then lies practically directly in front of a mechanic. With the proposed two-post lifts, the motor vehicle is raised in the usual way, that is to the Carrier arms attached to the slide are pivoted under the body floor of the motor vehicle and then the height of the slide is adjusted until they rest on the floor of the motor vehicle. A separate jack for lifting the motor vehicle is not necessary. The holding device is then connected to a fixed point on the motor vehicle. A safe solution is to remove two wheels after lifting the motor vehicle and then to place and fasten a perforated flange on each of the free-standing threaded pins of the brake drum, which flange is connected to the articulation point of the swivel arms on the slide via the connecting arm.

Anschließend werden die Schlitten in üblicher Weise hochgefahren. In der gewünschten Arbeitshöhe werden die Stelleinrichtungen synchron betätigt, so daß das Kraftfahrzeug quer zur Längsrichtung verschwenkt wird. Da übliche stationäre Zweisäulen-Hebebühnen meistens hydraulisch oder pneumatisch betätigt werden, bieten sich für die Verschwenkung ebenfalls hydraulische oder pneumatische Stellmotoren an. Ebenso ist eine Verschwenkung möglich über einen Arbeitszylinder, der mit einem Drehlager für die Tragarme verbunden ist.The sleds are then raised in the usual way. The actuating devices are actuated synchronously at the desired working height, so that the motor vehicle is pivoted transversely to the longitudinal direction. Since conventional stationary two-post lifts are mostly operated hydraulically or pneumatically, hydraulic or pneumatic servomotors are also suitable for swiveling. Swiveling is also possible via a working cylinder which is connected to a pivot bearing for the support arms.

Die Erfindung ist in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. In der Zeichnung stellen dar:

  • Figur 1 eine perspektivische Schemaansicht einer Zweisäulen-Hebebühne gemäß der Erfindung;
  • Figur 2 eine Seitenansicht der Zweisäulen-Hebebühne mit aufgesetztem Kraftfahrzeug;
The invention is explained in more detail in an exemplary embodiment with reference to the drawing. In the drawing:
  • Figure 1 is a perspective schematic view of a two column lift according to the invention;
  • FIG. 2 shows a side view of the two-post lift with the motor vehicle attached;

Eine stationäre Zweisäulen-Hebebühne 1 weist zwei senkrechte Säulen 2 auf, die jeweils mittels einer Bodenplatte 3 am Boden einer Kraftfahrzeugwerkstätte befestigt sind. Längs der beiden Säulen 2 ist jeweils ein Schlitten 4 verschiebbar gelagert. Die Verschiebung erfolgt überlicherweise mit Hilfe eines Spindeltriebes oder auch hydraulisch. Mit jedem Schlitten 4 ist ein Stellmotor 5 verbunden, dessen Drehteil 6 um eine horizontale Achse A gedreht werden kann. Diese Drehachse A ist für beide Stellmotoren gemeinsam. An jedem Drehteil 6 ist ein Aufnahmerahmen 7 befestigt, an dessen beiden Enden jeweils ein Tragarm 8 schwenkbar angelenkt ist. Die in der Länge einstellbaren Tragarme 8 weisen an ihren Enden Stützplatten 9 auf.A stationary two-column lift 1 has two vertical columns 2, each of which is fastened to the floor of a motor vehicle workshop by means of a base plate 3. A carriage 4 is slidably mounted along each of the two columns 2. The shift is usually carried out with the aid of a spindle drive or hydraulically. A servomotor 5 is connected to each carriage 4, the rotating part 6 of which can be rotated about a horizontal axis A. This axis of rotation A is common to both servomotors. On each rotating part 6, a receiving frame 7 is attached, at the two ends of which a support arm 8 is pivotally articulated. The length-adjustable support arms 8 have support plates 9 at their ends.

Ein Kraftfahrzeug 10 (Figur 2) wird bei abgesenkten Schlitten 4 zwischen die beiden Säulen 2 gefahren, anschließend werden die mit Hilfe der Stellmotoren 5 horizontal gehaltenen Tragarme 8 so unter das Kraftfahrzeug geschwenkt, daß die Stützplatten 9 sichere Karosseriepunkte des Kraftfahrzeuges 10 untergreifen können. Das Kraftfahrzeug wird anschließend leicht angehoben, so daß die Räder des Kraftfahrzeuges, z. B. die Vorderräder 11 abmontiert werden können. Auf die jetzt freiliegenden Gewindebolzen wird jeweils ein Lochflansch 12 aufgesteckt und verschraubt, der über einen längenveränderlichen, jedoch in der Länge fixierbaren Verbindungsarm 13 schwenkbar mit dem Aufnahmerahmen 7 verbunden ist. Danach ist das Kraftfahrzeug 10 lagemäßig auf der Zweisäulen-Hebebühne 1 fixiert. In Figur 1 ist nur einer der verwendeten Verbindungsarme 13 mit dem Lochflansch 12 gezeigt.A motor vehicle 10 (Figure 2) is moved with the carriage 4 lowered between the two columns 2, then the support arms 8 held horizontally with the aid of the servomotors 5 are pivoted under the motor vehicle such that the support plates 9 can reach under the body points of the motor vehicle 10. The motor vehicle is then raised slightly so that the wheels of the motor vehicle, for. B. the front wheels 11 can be removed. A hole flange 12 is attached and screwed onto each of the now exposed threaded bolts, which is pivotally connected to the receiving frame 7 via a connecting arm 13 which is variable in length but can be fixed in length. Thereafter, the motor vehicle 10 is fixed in position on the two-post lift 1. In Figure 1, only one of the connecting arms 13 used is shown with the perforated flange 12.

Das derart auf der Zweisäulen-Hebebühne 1 fixierte Kraftfahrzeug wird in üblicher Weise in die gewünschte Arbeitshöhe durch synchrones Verfahren der Schlitten 4 angehoben und anschließend durch Einschalten der Stellmotoren 5 um die beiden Stellmotoren gemeinsame horizontale Achse A verschwenkt. Das Kraftfahrzeug kann in eine geneigte Stellung entsprechend Figur 2 überführt werden.The motor vehicle fixed in this way on the two-column lifting platform 1 is raised in the usual manner to the desired working height by synchronously moving the carriage 4 and then pivoted about the horizontal axis A common to the two servomotors by switching on the servomotors 5. The motor vehicle can be moved into an inclined position according to FIG. 2.

Die Verschwenkung der Tragarmpaare um die Achse A kann, wie in Figur 1 gestrichelt dargestellt, auch über einen Hebelmechanismus, z. B. mit Hilfe eines Hydraulikzylinders 14 erfolgen, der zwischen dem Schlitten 4 und dem gegebenenfalls verlängerten Aufnahmerahmen 7 eingespannt ist.The pivoting of the pairs of support arms about the axis A can, as shown in dashed lines in Figure 1, also via a lever mechanism, for. B. with the aid of a hydraulic cylinder 14 which is clamped between the carriage 4 and the optionally extended receiving frame 7.
