Description

DEUTSCHESGERMAN

Die Erfindung geht aus von einer hydraulischen, ebenerdig versenkbaren Hebebühne für Kraftfahrzeuge od. dgl., wobei die BodenveLtieiiiiigenb£im_ Anheben der Bühne selbsttätig durch Platten abgedeckt werden, und ist gekennzeichnet durch an der Bühne angeordnete Schrägschlitzführungen, die über Rollen und Viergelenkgetriebe Nocken zum Anheilen der Abdeckplatten steuern.The invention is based on a hydraulic lift for motor vehicles or the like, which can be lowered to ground level, whereby the BodenveL tieiiiiigen - b £ im_ to lift the stage are automatically covered by plates , and is characterized by inclined slot guides arranged on the stage, which over rollers and four-bar gear control cams for healing the cover plates.

Bei den bekannten Hebebühnen werden die Abdeekplatten mittels Federn oder pneumatischer Zylinder angehoben, die gemäß der Erfindung in Fortfall kommen.In the known lifting platforms, the cover plates are made by means of springs or pneumatic cylinders raised, which come according to the invention in elimination.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht, und zwar zeigenAn embodiment of the invention is illustrated in the drawing, namely show

Fig. 1 und 2 perspektivische Ansichten der Hebebühne, 1 and 2 perspective views of the lifting platform,

Fig. 3 einen Schnitt nach der Linie 3-3 in Fig. 1, Fig. 4 einen Schnitt nach der Linie 4-4 in Fig. 3, Fig. 5 eine Draufsicht der Hebebühne,Fig. 3 is a section along the line 3-3 in Fig. 1, Fig. 4 is a section along the line 4-4 in Fig. 3, Fig. 5 is a plan view of the lifting platform,

Fig. 6 eine Seitenansicht zu Fig. 5 und Fig. 7 einen Schnitt nach der Linie 7-7 in Fig. 5.FIG. 6 shows a side view of FIG. 5 and FIG. 7 shows a section along line 7-7 in FIG. 5.

Die Hebebühne besteht aus zwei Tragschienen 10, die starr mit den hydraulischen Hubstempeln 12 verbunden und in der Ruhestellung in den Bodenvertiefungen 18 versenkt sind. In den Vertiefungen 18 liegen weiterhin die Abdeckplatten 22 sowie deren Antriebsorgane.The lifting platform consists of two support rails 10 which are rigidly connected to the hydraulic lifting rams 12 and are sunk in the floor depressions 18 in the rest position. In the wells 18 continue to be the cover plates 22 and their drive elements.

In Böcken 26 sind Wellen 28 gelagert, die mit zwei Nocken 30 und einem Hebel 58 fest verbunden sind. Auf den Nocken 30 liegen Abdeckplatten 22. Dicht am Hubstempel 12 ist in Lagern 32 eine Welle 36 angeordnet, an der ein Arm 38 mit Steuerrolle 40 sowie zwei Ffebel 52 befestigt sind. An der Bühne 10 ist ■ eine Platte 42 befestigt, die einen schrägen Schlitz 50 aufweist. Die Platte 42 ragt in Ruhestellung durch eine Öffnung 44 der Abdeckplatte 22 hindurch.Shafts 28, which are firmly connected to two cams 30 and a lever 58, are mounted in blocks 26. Cover plates 22 lie on the cams 30. A shaft 36 is arranged close to the lifting ram 12 in bearings 32, on which an arm 38 with control roller 40 and two Ffebel 52 are attached. On stage 10 is ■ a plate 42 is attached, which has an inclined slot 50. The plate 42 protrudes through in the rest position an opening 44 of the cover plate 22 therethrough.

Die an der Welle 36 angeordneten Hebel 52 sind über einstellbare Gestänge 54, 56 mit den Hebeln 58 an den Wellen 28 gelenkig verbunden. Die Länge der Hebel 52 und 58 ist so gewählt, daß eine verhältnismäßig geringe Drehung der Welle 36 in eine Vierteldrehung der Welle 28 übersetzt wird.The levers 52 arranged on the shaft 36 are connected to the levers 58 via adjustable rods 54, 56 articulated on the shafts 28. The length of the levers 52 and 58 is chosen so that a relative small rotation of the shaft 36 is translated into a quarter turn of the shaft 28.

Die Wirkungsweise der Vorrichtung zum Bewegen der Abdeckplatten 22 ist folgende: In Ruhestellung Iiefindet sich die Bühne 10 in gleicher Ebene mit dem Fußboden 20 (Fig. 6). Beim Anheben der Bühne wird mittels der in den Schrägschlitz 50 eingreifenden Steuerrolle 40 die Welle 36 und die daran befestigten Hebel 52, entgegen dem Uhrzeigersinne, gedreht. Diese Drehbewegung wird über die Gestänge 54, 56 und die FIebel 58 auf die Wellen 28 übertragen, wobei die Nocken 30 die Abdeckplatten 22 in Flurhöhe anheben. Die Form der Nocken 30 und des Schrägschlitzes 50 ist so aufeinander abgestimmt, daß die Hydraulische Hebebühne, insbesondere für Kraftfahrzeuge od. dgl. The mode of operation of the device for moving the cover plates 22 is as follows: In the rest position Iie, the stage 10 is in the same plane as the floor 20 (FIG. 6). When the stage is raised, the shaft 36 and the levers 52 attached to it are rotated counterclockwise by means of the control roller 40 engaging in the inclined slot 50. This rotary movement is transmitted to the shafts 28 via the rods 54, 56 and the levers 58, the cams 30 lifting the cover plates 22 at floor level. The shape of the cams 30 and the inclined slot 50 is coordinated so that the hydraulic lifting platform, especially for motor vehicles or the like.

Abdeckplatten 22 langsamer aufwärts liewegt werden als die Bühne 10 und somit eine gegenseitige Behinderung ausgeschlossen ist.Cover plates 22 are moved upward more slowly than the stage 10 and thus a mutual hindrance is excluded.

Sind die Abdeckplatten 22 in Flurhöhe angehoben, so liegen sie auf zwei Punkten 70 der Nocken 30 auf (Fig. 3). Dadurch wird ein unbeabsichtigtes Zurückdrehen der Nocken verhindert.If the cover plates 22 are raised at floor level, they rest on two points 70 of the cams 30 (Fig. 3). This prevents the cams from turning back unintentionally.

Da sich bei angehobener Bühne die Lage der Steuerrolle 40 nicht verändern kann, gelangt sie beim Senken der Bühne wieder in Eingriff mit dem Schrägschlitz 50, wobei sie die Nocken 30 zurückdreht. Dabei senken sich die Abdeckplatten 22 durch ihr Eigengewicht ab. Der Schrägschlitz 50 geht in einen senkrechten Schlitz 64 über, wodurch ein Absenken der Bühne 10 in Flurhöhe ermöglicht wird, ohne daß sie mit den Abdeckplatten 22 zusammenstößt.Since the position of the control roller 40 cannot change when the platform is raised, it arrives when it is lowered the stage again engages the inclined slot 50, rotating the cams 30 back. Included the cover plates 22 are lowered by their own weight. The inclined slot 50 goes into a vertical one Slot 64 over, whereby a lowering of the stage 10 is made possible in the hallway without it collides with the cover plates 22.

Die Erfindung ist auch bei Einstempelbühnen mit X- oder H-Rahmen anwendbar.The invention can also be used in single-stamp platforms with an X or H frame.
