Abstract

Ein Stampfgerät (1) zur Bodenverdichtung weist eine stampfend angetriebene Arbeitsmasse (4), die von einem zu einer Obermasse (2) gehörenden Motor über einen Kurbeltrieb, einen Kolben (16) und einen Federsatz (3) linear hin und her bewegbar ist, auf. Der Federsatz (3) besteht aus mindestens einer bei einer Hinbewegung des Kolbens (16) komprimierbaren ersten Feder (17) und mindestens einer bei einer Herbewegung des Kolbens (16) komprimierbaren zweiten Feder (18). Um die axiale Baulänge des Federsatzes zu reduzieren und damit die Höhe des Stampfgeräts zu vermindern und ein leichteres Arbeiten unter beengten Platzverhältnissen zu ermöglichen, wird vorgeschlagen, dass die mindestens eine zweite Feder (18) innerhalb eines Freiraums (F) im Inneren der mindesten einen ersten Feder (17) angeordnet ist. Alternativ wird ein Stampfgerät mit einem Federsatz vorgeschlagen, bei dem alle Federn bei der Hinbewegung des Kolbens Druckkräfte und bei der Herbewegung des Kolbens Zugkräfte auf die Arbeitsmasse übertragen.

Figure imgaf001
A ramming device (1) for soil compaction has a pounding driven working mass (4), which is linearly reciprocally movable from a to an upper mass (2) engine via a crank mechanism, a piston (16) and a spring set (3) , The spring set (3) consists of at least one first spring (17) which can be compressed during a forward movement of the piston (16) and at least one second spring (18) which can be compressed during a movement of the piston (16). In order to reduce the axial length of the spring assembly and thus to reduce the height of the ramming device and to allow easier work in confined spaces, it is proposed that the at least one second spring (18) within a free space (F) in the interior of at least a first Spring (17) is arranged. Alternatively, a ramming device with a spring set is proposed, in which all springs transmit compressive forces during the forward movement of the piston and tensile forces on the working mass during the movement of the piston.
