Abstract

La présente invention concerne une glissière de sécurité intelligente à déplacement vertical comprenant deux cadres principaux (1), deux cadres à déplacement vertical (2) et une pluralité de cordes de protection (15). Le cadre à déplacement vertical (2) est relié en coulissement à une extrémité supérieure d'un côté interne du cadre principal (1). La corde de protection (15) est reliée entre les deux cadres à déplacement vertical. Un premier moteur d'entraînement (3) est monté à demeure au fond d'une surface latérale avant du cadre principal (1). Une poulie de synchronisation inférieure (4) est montée sur un arbre de sortie du premier moteur d'entraînement (3). Une plaque de montage en forme de L (5) est reliée à demeure à la surface latérale avant du cadre principal au moyen d'un boulon. La glissière de sécurité a une structure simple en forme de récipient et un aspect net et innovant. Le cadre à déplacement vertical se déplace verticalement de manière à placer et à retirer les cordes de protection, ce qui permet de gérer automatiquement un espace que les passagers peuvent traverser à des intervalles. L'invention présente une large gamme d'applications, un faible taux de défaillance, une longue durée de vie et un niveau de sécurité élevé. La glissière de sécurité utilise la corde de protection à structure flexible et ne s'affaisse pas lorsqu'elle s'étend sur une grande distance, ce qui garantit un niveau de sécurité élevé, de résoudre le problème du poids lourd d'un élément de liaison dur et de pallier le défaut d'affaissement d'une structure flexible.
