Abstract

Die Erfindung betrifft eine Sicherungseinrichtung (8) zur Sicherung einer zur Bewegung einer Last (2) vorgesehenen Bewegungseinrichtung (1) gegen unkontrolliert ausgeführte Bewegungen der Last (2) bei Abweichung von zumindest einer vorgesehenen Betriebsbedingung der Bewegungseinrichtung (1), wobei die Sicherungseinrichtung (8) ein Sicherungselement (5) umfaßt, das bei Abweichung von der zumindest einen vorgesehenen Betriebsbedingung, insbesondere einer Abweichung einer vorgesehenen Größe einer auf die Sicherungseinrichtung (8) einwirkenden Kraft, eine Notstopp-Arretierung durch Betätigung des Sicherungselement (5)s auslöst. Um bei einer solchen Sicherungseinrichtung (8) deren Funktionssicherheit zu verbessern, so daß sie bei Eintritt eines Notstoppereignisses möglichst unmittelbar stoppt und hierbei möglichst höchstens gering beschädigt wird, wird vorgeschlagen, daß das Sicherungselement (5) ein Führungselement (3) umgibt und dabei derart angeordnet ist, daß das Sicherungselement (5) bei Einhaltung der zumindest einen vorgesehenen Betriebsbedingung zumindest im Wesentlichen in der vorgesehenen Bewegungsrichtung relativ zum Führungselement (3) frei beweglich angeordnet und entlang oder zumindest parallel zu einer Längsachse (3b) der vorgesehenen Bewegungsrichtung zusammen mit einem Träger der Sicherungseinrichtung (8), an dem das Sicherungselement (5) gelagert ist, bewegbar ist, und Mittel vorgesehen sind, aufgrund denen bei einer Abweichung von der zumindest einen Betriebsbedingung, das Sicherungselement (5) eine Kippbewegung ausführt, aufgrund der das Sicherungselement (5) verkantet gegen das Führungselement (3) angeordnet wird.

The invention relates to a securing device (8) for securing a movement device (1) provided for moving a load (2) against uncontrolled movements of the load (2) in the event of deviation from at least one intended operating condition of the moving device (1), wherein the securing device (8 ) comprises a securing element (5) which triggers an emergency stop locking by actuation of the securing element (5) s in the event of deviation from the at least one intended operating condition, in particular a deviation of an intended size of a force acting on the securing device (8). In order to improve in such a security device (8) their reliability, so that when an emergency stop event stops as directly as possible and this is minimally damaged, it is proposed that the securing element (5) surrounds a guide element (3) and thereby arranged is that the securing element (5) arranged at least substantially in the intended direction of movement relative to the guide element (3) freely and along or at least parallel to a longitudinal axis (3b) of the intended direction of movement together with a carrier of the at least one intended operating condition Securing device (8) on which the securing element (5) is mounted, is movable, and means are provided, on the basis of which, in a deviation from the at least one operating condition, the securing element (5) performs a tilting movement, due to which the securing element (5) tilted against that Guide element (3) is arranged.
