Abstract

L'invention porte sur un dispositif anti-mou de câble d'ascenseur qui comprend une plaque d'extrémité de câble (8), un élément rotatif (2), un cadre de fixation d'interrupteur (3) et un cadre de support de l'élément rotatif. Sous la plaque d'extrémité de câble (8), l'élément rotatif (2) est suspendu par le cadre de support de l'élément rotatif et un interrupteur de sécurité (4) est suspendu par le cadre de fixation d'interrupteur (3). Le cadre de support de l'élément rotatif comprend une plaque de support et de fixation (6) et une colonne de support élastique. Une extrémité de la plaque de support et de fixation (6) est raccordée de manière fixe à la plaque d'extrémité de câble (8), et l'autre extrémité est articulée à l'élément rotatif (2) par une broche de tige (7). La colonne de support élastique comprend une tige à tarière et un ressort de compression (5) chemisé autour de la tige à tarière. Lorsque l'élément rotatif (2) est comprimé de manière à tourner autour de la broche de tige, la plaque de butoir d'interrupteur pousse le contact mobile de l'interrupteur de sécurité (4). Le dispositif peut couper automatiquement l'alimentation électrique pour freiner l'ascenseur de sorte qu'un accident de collision causé par la rupture du câble d'acier pendant la course de la cabine soit évité de manière efficace et que la sécurité de l'ascenseur soit garantie lorsque l'ascenseur est en action. La qualité du produit peut être efficacement améliorée.
