Description

Es sind Greifzangen beispielsweise für Tiefofenkrane bekannt, bei denen der Stahlblock durch die mit Körnerspitzen versehenen Zangenschenkel gefaßt wird, und wobei diese Zangenschenkel in einem Zangenkopf angeordnet sind, der an einer Zangensäule hängt. In dieser Zangensäule befinden sich auch Gewindespindeln, durch die die Zangenschenkel gespreizt werden, um gegebenenfalls einen Vordruck oder eine Vorspannung auf den zu transportierenden Block auszuüben. Es kann nun vorkommen, daß die zu fassende und zu hebende Last nicht immer in ein und derselben Ebene liegt, daß z. B. Blöcke, Brammen oder Platinen räumlich in einem gewissen Grade schräg liegen. Andererseits haben die Zangen nur eine gewisse Maulweite, und es ist daher nicht möglich, die schräg liegenden Blöcke, Brammen oder Platinen izu ergreifen.There are gripping tongs known, for example, for deep furnace cranes which the steel block grasped by the tong legs provided with punch tips is, and these pliers legs are arranged in a pliers head, which is on hangs on a pliers column. There are also threaded spindles in this pliers column, through which the pliers legs are spread apart to possibly create a form or to apply a preload to the block to be transported. It can now it can happen that the load to be grasped and lifted is not always in one and the same Level is that z. B. blocks, slabs or blanks spatially in a certain way Lie at an angle. On the other hand, the pliers only have a certain mouth width, and it is therefore not possible to izu the slanted blocks, slabs or blanks seize.

Um nun ein solches Transportgut fassen zu können, wird die Zange erfindungsgemäß in einer Art Kardananordnung an der sonst starr geführten Hubsäule ,aufgehängt. Dabei ist die Säule selbst kardanbeweglich ausgebildet und als solche in einem starren Säulenschacht geführt. Der Antrieb des Schließwerkes erfolgt durch eine Kardanwelle. Es besteht aus einer Gewindespindel, deren Mutter die Spreizung bewirkt. Der Vorteil dieser kardanmäßigen Anordnung bzw. Aufhängung ist ohne weiteres einzusehen. In Sonderheit ist es aber auch aus der Zeichnung zu entnehmen, in der ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt ist. In einem starren Säulenschacht i ist eine Hubsäule z, die mit einem Zangenkopf 3 mittels eines Rohres 4. kardanmäßig verbunden ist, geführt. Das Schließen und Öffnen der Zangenschenkel 5 erfolgt über eine Kardanwelle 6, die mit einer Gewindespindel 7 gelenkig verbunden und in der kardanbeweglichen Hubsäule geführt ist.In order to be able to grasp such a transport item, the pliers are according to the invention suspended in a kind of cardan arrangement on the otherwise rigidly guided lifting column. The column itself is designed to be movable with gimbals and, as such, is rigid Column shaft led. The locking mechanism is driven by a cardan shaft. It consists of a threaded spindle, the nut of which causes the expansion. The advantage this gimbal-like arrangement or suspension can be seen without further ado. In However, a specialty can also be found in the drawing, in which an exemplary embodiment of the subject matter of the invention is shown. In a rigid column shaft i is a lifting column z, which is gimbal-like with a pincer head 3 by means of a tube 4 connected, led. The pliers legs 5 are closed and opened via a cardan shaft 6, which is articulated to a threaded spindle 7 and in the cardan-movable lifting column is guided.
