Abstract

La présente invention porte sur un bâti de tige de déflecteur de poulie de positionnement de poids mort, lequel bâti comprend deux supports de tige de déflecteur (1), une première tige de liaison (2), une seconde tige de liaison (3) et une tige de poids d'équilibrage (4). Le support de tige de déflecteur (1) comprend un premier corps de support (11), un deuxième corps de support (12) et un troisième corps de support (13). Une extrémité du premier corps de support (11), du deuxième corps de support (12) et du troisième corps de support (13) sont fermement reliées, et un trou d'arbre (14) est formé à la jonction des trois corps de support. Un angle est formé entre le premier corps de support (11) et le troisième corps de support (13), d'environ 139 à 188 degrés. Un autre angle est formé entre le premier corps de support (11) et le deuxième corps de support (12), d'environ 68 à 131 degrés. Les premiers corps de support (11) des deux supports de tige de déflecteur (1) sont reliés par la première tige de liaison (2), les deuxièmes corps de support (12) des deux supports de tige de déflecteur (1) sont reliés par la seconde tige de liaison (3), et les troisièmes corps de support (13) des deux supports de tige de déflecteur (1) sont reliés par la tige de poids d'équilibrage (4). Le bâti de tige de déflecteur comporte de façon coaxiale une poulie et peut tourner par rapport à la poulie, et peut également empêcher des cordons de fil d'acier, des câbles, et analogues, d'être séparés vis-à-vis de la poulie. La présente invention porte également sur un bras de levage de grue, lequel bras comprend le bâti de tige de déflecteur de poulie de positionnement de poids mort.
