Description
Es sind bereits beidseitig am Fahrgestell angeordnete Wagenheber bekanntgeworden, welche mit Druckmittelantrieb versehen sind. Eine von Hand oder motorisch angetriebene Pumpe liefert das Druckmittel, welches durch ein Steuerventil in gewünschter Weise den einzelnen Hebern zugeleitet wird. Es ist auch bereits bekannt, solche Heber als Scherenheber auszubilden. Ferner ist es bereits bekanntgeworden, bei Teleskophebern eine Schutzhülse anzuordnen.There are already known jacks arranged on both sides of the chassis, which are provided with a pressure medium drive. One driven by hand or motor The pump supplies the pressure medium, which is controlled by a control valve in the desired manner is fed to individual lifters. It is also already known such jacks as scissor jacks to train. Furthermore, it has already become known to arrange a protective sleeve in telescopic jacks.
Die Erfindung bezdeht sich auf eine Hebevorrichtung mit Nürnberger Schere und Druckmittelantrieb zwischen zwei senkrecht übereinanderliegenden Gelenken und besteht darin, daß der Druckmittelantrieb aus einem Teleskopheber besteht, dessen unterster Kolben am Fußpunkt einer am unteren Gelenk befestigten, in zusammengeklapptem ZustandThe invention relates to a lifting device with Nuremberg scissors and Pressure medium drive between two vertically superimposed joints and consists in that the pressure medium drive consists of a telescopic jack, the lowest piston of which at the base of one attached to the lower joint, in the folded state
ao als Schutzmantel für den Teleskopheber dienenden Hülse befestigt ist und dessen oberster Zylinder an dem oberen Scherengelenk sitzt.ao is attached as a protective jacket for the telescopic jack serving sleeve and its topmost Cylinder sits on the upper scissor joint.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigt:The drawing shows an embodiment of the subject matter of the invention, namely shows:
Abb. ι eine Ansicht einer Hebevorrichtung ini offener und Abb. 2 eine Ansicht der Hebevorrichtung in geschlossener Stellung.Fig. Ι a view of a lifting device in the open and Fig. 2 is a view of the lifting device in closed position.
Die Hebevorrichtung besteht aus einem Druckzylinder und zwei Nürnberger Scheren. Ein Kopfstück 1 ist unter dem Träger des Fahrgestells zwischen den Vorder- und Hinterrädern des -Wagens festgeschraubt. An diesem Kopfstück ist der Teil 3 des Zylinders angelenkt. Die Lenker 2 sind mit dem Zylinderkörper 3 verbunden. In dem: Teil 3 ist der teleskopartige Kolben 4, 5 verschiebbar. Der untere Teil 5 des Kolbens trägt eine Hülse 6, welche oben offen ist und an der oben die mittleren Gelenke 7 der beiden Scheren an- * greifen. Die Eckgelenke der Scheren tragen an sich bekannte Federn 8, welche die Schere zu schließen bestrebt sind, wobei sie die Druckflüssigkeit wieder zur Pumpe zurückdrücken. The lifting device consists of a pressure cylinder and two Nuremberg scissors. A head piece 1 is under the support of the chassis between the front and rear wheels of the car screwed tight. Part 3 of the cylinder is hinged to this head piece. The handlebars 2 are with the cylinder body 3 connected. In the: Part 3, the telescopic piston 4, 5 is displaceable. Of the lower part 5 of the piston carries a sleeve 6 which is open at the top and at the top the Attack the middle joints 7 of the two scissors *. Carry the corner joints of the scissors known springs 8, which strive to close the scissors, with the Press hydraulic fluid back to the pump.
Die unteren Gelenke der Scheren greifen an einer Bodenstütze 9 an. Letztere übergreift bei geschlossener Schere den zugehörigen Zylinder und die zugehörige Hülse 6. Am Kopf des Zylinderteils 3 ist ein Anschlußstutzen 10 für das Druckmittel angebracht.The lower joints of the scissors engage a floor support 9. The latter overlaps with the scissors closed, the associated cylinder and the associated sleeve 6. Am At the head of the cylinder part 3, a connecting piece 10 is attached for the pressure medium.
Eine solche Hebevorrichtung wird auf beiden Seiten des Wagens angeordnet, und in bekannter Weise wird durch eine Pumpe das Druckmittel geliefert, welches durch ein Steuerventil in gewünschter Weise den einzelnen Hebevorrichtungen zugeleitet wird. Es ist dabei ohne weiteres möglich, entweder nur eine der beiden Hebevorrichtungen oder beide gleichzeitig zu betätigen.Such a lifting device is placed on both sides of the trolley, and in a known manner Way, the pressure medium is supplied by a pump, which through a control valve in the desired manner the individual Lifting devices is fed. It is easily possible, either only to operate one of the two lifting devices or both at the same time.
