Description
KAISERLICHESIMPERIAL
PATENTAMT,PATENT OFFICE,
Vorliegende Erfindung bezieht sich auf einen Hebebock, und es besteht das Wesentliche derselben darin, daß zwischen der Hebetraverse und einer am Fuße des Gerüstes fest angebrachten Traverse Schraubenfedern angeordnet werden, deren in ihrem zusammengepreßten Zustand aufgespeichertes Arbeitsvermögen zur Unterstützung der Hebearbeit verwendet wird.The present invention relates to a jack, and there is the gist the same in that between the lifting beam and one at the foot of the scaffolding stuck attached traverse coil springs are arranged, their compressed in their State of accumulated work capacity is used to support lifting work.
ίο Auf der beiliegenden Zeichnung ist ein solcher Hebebock beispielsweise dargestellt. Wie ersichtlich, ist dieser nur mit einer in einer Spindelmutter B geführten Spindel C ausgerüstet, es können jedoch ebensogut zwei oder noch mehr Spindeln Verwendung finden.ίο Such a jack is shown in the accompanying drawing, for example. As can be seen, this is only equipped with a spindle C guided in a spindle nut B , but two or more spindles can just as well be used.
Die bewegliche Hebetraverse E ist einerseits auf dem Spindelkopf c gelagert, andererseits auf dem oberen Ende der beiden Rohre J, die in der Traverse α des Bockgestelles leicht gleitend geführt und mit ihrem unteren Ende an der Traverse j befestigt sind, wobei letztere gleichzeitig zur Versteifung des ganzen Systems dient. Zwischen der Traverse E und der Fußplatte des Bockgestelles werden Schraubenfedern K angeordnet; diese liegen in den Rohren J und werden durch die Stangen L, welche bis zur Traverse α reichen, geführt.The movable lifting traverse E is mounted on the one hand on the spindle head c , on the other hand on the upper end of the two tubes J, which are guided in the traverse α of the trestle frame and are attached with their lower end to the traverse j , the latter at the same time to stiffen the the whole system. Helical springs K are arranged between the traverse E and the base plate of the trestle frame; these lie in the tubes J and are guided by the rods L, which extend to the cross member α.
Beim Niederlassen des Hebebockes werden die Federn K zusammengepreßt; wird der Hebebock nun zum Heben irgend einer Last verwendet, so wird die hierzu erforderliche Arbeit zum Teil von den Federn K geleistet, indem hierbei die vorher durch das Zusammendrücken der Federn aufgespeicherte Energie wieder frei wird. Auf diese Weise wird eine wesentliche Erleichterung der Hebearbeit erreicht. When lowering the jack, the springs K are compressed; If the jack is now used to lift any load, the work required for this is partly done by the springs K , in that the energy previously stored by the compression of the springs is released again. In this way, the lifting work is made considerably easier.
