Title (EN) FAIL-SAFE DEVICE FOR QUICK COUPLER
(FR) DISPOSITIF À SÉCURITÉ INTÉGRÉE POUR RACCORD RAPIDE
(KO) 퀵 커플러의 2중 안전장치
Abstract: front page image
(EN)The present invention relates to a fail-safe device for a quick coupler, which, in a coupling process of a quick coupler for connecting a heavy equipment attachment and an excavator, automatically prevents unintentional separation between an attachment pin and a fixed hook, and enables a locking device to be automatically operated in association with a cylinder operation for slidably moving a hitch and elastic force of first and second compression springs. The fail-safe device for a quick coupler according to the present invention comprises: a quick coupler body mounted to an end of an excavator arm and a push link; a fixed hook disposed on one side of the quick coupler body and coupled to a first attachment pin; a hitch disposed on the other side of the quick coupler body and engaged with or disengaged from a second attachment pin according to an operation of a hydraulic cylinder; and a locking means which is operated in association with a cylinder operation for operating the hitch, and prevents unintentional release of a coupling state between the fixed hook and the first attachment pin by compressive elastic force of first and second compression springs.
(FR)La présente invention concerne un dispositif à sécurité intégrée pour un raccord rapide, qui, dans un processus de couplage d’un raccord rapide pour raccorder un accessoire d’équipement lourd et une pelleteuse, empêche automatiquement une séparation involontaire entre une broche de fixation et un crochet fixe, et permet qu’un dispositif de verrouillage soit automatiquement actionné en association avec une opération de vérin pour déplacer de façon coulissante un attelage et une force élastique de premier et deuxième ressorts de compression. Le dispositif à sécurité intégrée pour un raccord rapide selon la présente invention comprend : un corps de raccord rapide monté à une extrémité d’un bras de pelleteuse et une transmission de poussée ; un crochet fixe disposé sur un côté du corps de raccord rapide et couplé à une première broche de fixation ; un attelage disposé sur l’autre côté du corps de raccord rapide et mis en prise ou hors prise avec une deuxième broche de fixation en fonction d’un actionnement d’un vérin hydraulique ; et un moyen de verrouillage qui est actionné en association avec une opération de vérin pour actionner l’attelage, et empêche une libération non intentionnelle d’un état de couplage entre le crochet fixe et la première broche de fixation par la force élastique de compression de premier et deuxième ressorts de compression.
(KO)본 발명은 중장비용 어태치먼트와 굴삭기를 연결하기 위한 퀵 커플러의 연결과정에서 어태치먼트 핀과 고정훅간의 임의 이탈을 자동으로 방지하도록 함과 아울러, 히치를 슬라이딩 이동시키는 실린더의 동작 및 제1,2압축스프링의 탄성력과 연계 동작되어 자동으로 록킹장치의 동작이 가능하도록 한 퀵 커플러의 2중 안전장치에 관한 것이다. 본 발명에 따른 퀵 커플러의 2중 안전장치는, 굴삭기 암의 단부와 푸시링크에 장착되는 퀵 커플러 바디와, 퀵 커플러 바디의 일측에 마련되고 제 1어태치먼트 핀과 결합되는 고정훅과, 퀵 커플러 바디의 타측에 마련되고 유압 실린더의 동작에 따라 제 2어태치먼트 핀과 결합 및 해제되는 히치와, 히치를 동작시키는 실린더의 동작과 연계 동작되고 제1,2압축스프링의 압축 탄성력에 의해 고정훅과 제 1어태치먼트 핀의 결합상태가 임의로 해제되는 것을 예방하기 위한 록킹수단으로 구성된다.
