The invention relates to the technical field of building construction, in particular to a steel pipe column swivel hoisting device and method. The steel pipe column swivel hoisting device comprises acarrying pole beam and two fixed pulleys, the upper portion of the carrying pole beam is provided with a first steel wire rope used for being connected with a hoisting mechanical hook, second steel wire ropes are wound around the fixed pulleys, and the two ends of the second steel wire ropes are used for being connected with lifting lugs on the inner wall of a steel pipe column correspondingly; and the two fixed pulleys are arranged in a spaced mode in the horizontal direction and are configured in the mode that the acting force of the two fixed pulleys on the carrying pole beam is located atthe position, with the resultant moment being zero, of the carrying pole beam, the acting force of the two fixed pulleys on the carrying pole beam is located on the same vertical straight line with the acting point of the resultant force of the tension force of the first steel wire rope on the carrying pole beam and the gravity center position of the carrying pole beam, and the two fixed pulleys are symmetrically distributed relative to the gravity center position of the carrying pole beam. By means of the steel pipe column swivel hoisting device, it can be guaranteed that all the lifting lugson the steel pipe column are evenly stressed, and therefore the situation that safety risks occur due to uneven stress of the lifting lugs can be reduced.

    本发明涉及建筑施工技术领域,特别涉及一种钢管柱转体起吊的装置,和一种钢管柱转体起吊的方法。钢管柱转体起吊的装置,包括扁担梁和两个定滑轮,扁担梁的上部设有用于与起重机械吊钩连接的第一钢丝绳,定滑轮上缠绕有第二钢丝绳,第二钢丝绳的两端分别用于与钢管柱内壁上的吊耳连接;两个定滑轮在水平方向上间隔设置,且被配置为:两个定滑轮给扁担梁的作用力在扁担梁上合力矩为零的位置处,与第一钢丝绳给扁担梁拉力合力的作用点,以及与扁担梁的重心位置在同一竖直直线上,两个定滑轮相对扁担梁的重心位置对称分布。通过钢管柱转体起吊的装置可以保证钢管柱上所有的吊耳受力均匀,从而可以减少吊耳因受力不均而出现安全风险的情况发生。
