Description

Die Erfindung bezieht sich auf einen Teleskopwagenheber. The invention relates to a telescopic jack.

Es sind schon Heber bekanntgeworden, bei denen ein doppelter Auszug durch Bewegung zweier Hubstangen gegeneinander erreicht wird. Die Erfindung besteht darin, daß der Tragstempel und der Fußstempel durch eine endlose Kette verschoben werden, die über in dem Führungsgehäuse gelagerte Räder gespannt ist. Auf eine gute Führung der einzelnen verschiebbaren Teile kommt es dabei besonders an, damit die Stabilität des Wagenhebers auch in völlig ausgezogenem Zustande hinreichend gesichert· ist.There have already been known lifters in which a double pull-out through movement two lifting rods against each other is achieved. The invention consists in that the support stamp and the foot stamp can be moved by an endless chain that runs over in the guide housing stored wheels is tensioned. On good guidance of each sliding Parts are particularly important, so that the stability of the jack also in completely is adequately secured in the extended state.

Auf der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt; -es zeigen:In the drawing, the subject of the invention is shown in one embodiment; - show it:

Abb. ι einen senkrechten Schnitt durch den Heber,Fig. Ι a vertical section through the lifter,

Abb. 2 ebenfalls einen Schnitt, und zwar zur Abb. ι um 90 ° versetzt,Fig. 2 also shows a section, namely offset by 90 ° to Fig.

Abb. 3 einen horizontalen Schnitt durch den Heber.Fig. 3 is a horizontal section through the lifter.

Die Bewegung der Stempel α und b gegeneinander wird durch die Kettenräder c bewirkt, welche auf Achsen d gelagert sind. Diese Achsen c' sind im Gehäuse d gelagert. Die über die Kettenräder c geführte endlose Kette e ist bei a' mit dem Fußstempel α und bei V mit dem Tragstempel b verbunden. Die beiden Stempele und b besitzen Schlitze f und f, in denen sich die Achsen c' und die Kettenräder c bewegen. Außer der Führung des inneren Stempels b im Innern des äußeren Stempels α erfolgt noch eine weitere Führung durch den BundiT, was für den ausgezogenen Zustand wichtig ist.The movement of the punches α and b against each other is caused by the chain wheels c, which are mounted on axes d. These axes c ' are stored in the housing d. The endless chain e guided over the chain wheels c is connected to the foot stamp α at a ' and to the support stamp b at V. The two punches and b have slots f and f in which the axes c ' and the sprockets c move. In addition to guiding the inner punch b inside the outer punch α , there is another guiding through the BundiT, which is important for the extended state.

Zum Antrieb der Kette ist zweckmäßig eine der beiden Achsen c' als Welle ausgebildet, welche durch ein Schneckengetriebe angetrieben werden kann.To drive the chain, one of the two axes c 'is expediently designed as a shaft, which can be driven by a worm gear.
