Abstract

L'invention concerne un dispositif d'alimentation de goulotte supérieure de four pour un haut-fourneau. Ce dispositif comprend une enveloppe hermétique (1), un tube Venturi (3), un palier supérieur de plaque tournante (5), un manchon rotatif (4), une goulotte (7), un cadre universel (8), un palier inférieur de plaque tournante (6), un composant roue à cadran (37), un cylindre à huile (11) et un dispositif de transmission horizontal (10) pour amener le palier supérieur de plaque tournante (5) à tourner. Le tube Venturi (3) passe à travers un couvercle supérieur (2) sur la partie supérieure du boîtier hermétique (1) et s'étend dans le boîtier hermétique (1). Une baque interne de palier supérieur de plaque tournante (5) est reliée au couvercle supérieur (2). Le manchon rotatif (4) est relié à une bague externe du palier supérieur de plaque tournante (5). Le manchon rotatif (4) comporte un tourillon (12). La goulotte (7) est suspendue dans le manchon rotatif (4) par l'intermédiaire du tourillon (12). Le tourillon (12) est relié à une extrémité d'une manivelle (14). L'autre extrémité de la manivelle (14) est disposée dans une glissière (81) du cadre universel (8). Une bague interne du palier inférieur de plaque tournante (6) est reliée au cadre universel (8). Une extrémité du composant roue à cadran (37) est reliée à la bague interne du palier inférieur de plaque tournante (6). L'autre extrémité du composant roue à cadran (37) est située dans une fente de glissement du manchon rotatif (4). Le cylindre à huile (11) est utilisé pour forcer le palier inférieur de plaque tournante (6) à monter et à descendre. Le dispositif d'alimentation de goulotte supérieure de four pour un haut-fourneau a une chaîne de transmission courte et est stable en fonctionnement sans génération d'une force latérale sur un rail de guidage (16).
