The invention discloses a hoisting tool capable of realizing air turning of an escalator truss. The hoisting tool comprises a hook, wherein a rotating ring is arranged on the inner side of the top ofthe hook, a transmission shaft penetrates through the inner side of the rotating ring, a U-shaped ring of a U-shaped structure is arranged outside the rotating ring, the rotating ring is located on the inner side of the bottom of the U-shaped ring, the two ends of the U-shaped ring are in a circular ring shape and arranged at the two ends of the transmission shaft in a sleeving mode, a limiting column is fixed to the inner side of the top of the hook and penetrates into the rotating ring, a limiting protrusion of an arc-shaped structure is fixed to the side edge of the limiting column, a limiting groove allowing the limiting protrusion to be inserted is formed in the inner wall of the rotating ring, and the inner wall of the rotating ring is uneven; by means of the design, when the truss is hoisted, the truss can be overturned in the air according to actual operation requirements, various installation requirements are met, meanwhile, operation is quite convenient, the safety degree ishigh, and limitation in an existing device is greatly reduced.
本发明公开了一种可以实现自动扶梯桁架空中翻转的吊装工具,包括挂钩,所述挂钩的顶部内侧设置有转环,所述转环的内侧贯穿有传动轴,所述转环的外部设置有U型结构的U型环,且所述转环处于U型环的底部内侧,所述U型环的两端呈圆环状,并套设在传动轴的两端上,所述挂钩的顶部内侧固定有限位柱,所述限位柱贯穿至转环的内部,所述限位柱的侧边固定有弧形结构的限位凸起,所述转环的内壁开设有供限位凸起插入的限位槽,所述转环的内壁呈凹凸不平状;通过本发明的设计,可以在吊装桁架时,根据实际的操作需求在空中进行翻转,满足多种安装需求,同时操作起来十分方便,且安全度高,大大的缩小了现有装置中的局限性。
