Abstract

La présente invention concerne un dispositif verrou de sécurité pour un dispositif d'attache rapide qui empêche la libération arbitraire de l'état attaché d'un outil de travail installé sur un dispositif d'attache rapide à l'avant d'une excavatrice. Un dispositif verrou de sécurité pour un dispositif d'attache rapide de la présente invention est un dispositif d'attache rapide comprenant : un corps ; un crochet fixe formé d'un côté du corps et dans lequel est inséré un axe d'attache d'un outil de travail ; et un crochet mobile situé sur un côté faisant face au crochet fixe et pivotant en fonction de l'actionnement d'un cylindre pour verrouiller un autre axe d'attache de l'outil de travail. Des moyens de verrouillage de sécurité sont situés sur l'intérieur du corps pour que le crochet mobile et l'axe d'attache de l'outil de travail situés dans le crochet mobile ne soient pas séparés arbitrairement à cause du pivotement du crochet mobile, maintiennent fermement un état verrouillé même lorsqu'un cylindre est endommagé pendant le travail ou se déplace pendant que l'outil de travail est attaché au dispositif d'attache rapide, et empêchent la séparation ou la chute de l'outil de travail du dispositif d'attache rapide. Ainsi, des accidents provoquant des blessés ou des morts et endommageant la machinerie peuvent être évités, et la sécurité peut être assurée.
