Abstract
Fallsicherung des Lastteils von Hubgeräten im Falle des Versagens von Tragelementen, dadurch gekennzeichnet, dass mindestens ein, mit der Anbindung (2) von Tragelementen (1) zum Lastteil (5) und dem Lastteil (5) als solches, korrespondierendes und verstellbares Fangelement (6), durch Verstellen einen Formschluss mit dem Rahmen (7) und/oder einem Rahmenelement (8) herstellt. Fall protection of the load part of lifting devices in the event of failure of the support elements, characterized in that at least one, with the connection (2) of support elements (1) to the load part (5) and the load part (5) as such, corresponding and adjustable catch element (6 ), by adjusting a form fit with the frame (7) and / or a frame element (8).
Description
Hubgeräte dienen dem Zweck Lasten über eine vertikale Wegstrecke zu bewegen. Die dafür benötigte Bewegungsenergie wird über ein oder mehrere Tragelement(e) (z. B. Zahnriemen, Kette oder Spindel) auf das Lastteil übertragen. Das Lastteil ist das Teil bzw. die Baugruppe, welche(s) als Teil der Maschine die Bewegung vollzieht und alle Notwendigkeiten besitzt, die Last zu tragen, zu heben und zu senken. Das vertikale Bewegen von Lasten stellt unter Verwendung von Tragelementen eine potentielle Gefahr dar, da das Lastteil ggf. zusammen mit der Last bei einem Versagen des Tragelements ungehindert herabfallen, Sachschäden hervorrufen und Personen verletzen kann.Lifting devices are used to move loads over a vertical distance. The kinetic energy required for this is transferred to the load part via one or more support element (s) (e.g. toothed belt, chain or spindle). The load part is the part or assembly which, as part of the machine, performs the movement and has all the requirements to carry, lift and lower the load. The vertical movement of loads with the use of load-bearing elements represents a potential danger, since if the load-bearing element fails, the load part may fall down unhindered, causing property damage and injuring people.
Der im Hauptschutzanspruch angegebenen Erfindung liegt das Problem zugrunde, dass ein Versagen des Tragelements registriert und durch eine Mechanik, eine Verriegelung ausgelöst wird, welche das Herabfallen des Lastteils verhindert.The invention specified in the main protection claim is based on the problem that a failure of the support element is registered and a lock is triggered by a mechanism, which prevents the load part from falling.
Dieses Problem wird mit den Merkmalen, welche in den Schutzansprüchen, ausgeführt sind, gelöst.This problem is solved with the features which are set out in the protection claims.
Mit der Erfindung wird erreicht, dass, sollte das Tragelement eines Hubgeräts versagen, dieses Versagen durch eine mechanische Abfrage, mithilfe einer mit dem Lastteil verschiebbaren und unter (Feder-) Vorspannung stehenden Anbindung, ein damit verbundenes Fangelement in seiner Position so versetzt wird, dass dieses zusammen mit einer am Rahmen des Hubgeräts angebrachten Gegenkontur, einen Formschluss bildet, welcher ein Fallen des Lastteils verhindert.With the invention it is achieved that, should the support element of a lifting device fail, this failure is caused by a mechanical query, with the aid of a connection that is displaceable with the load part and is under (spring) pretension, an associated catch element is displaced in its position in such a way that this together with a counter-contour attached to the frame of the lifting device forms a form fit which prevents the load part from falling.
