The invention relates to the technical field of lifting appliance tools, and particularly discloses an annular multi-lifting-point lifting appliance structure which comprises a stand column. The stand column is vertically fixed on the connecting disc, a lifting appliance lifting lug is arranged at the top end of the stand column, and a rigging lifting shackle for moving the lifting appliance is mounted on the lifting appliance lifting lug; a plurality of main supporting rods are arranged on the connecting disc in an annular array mode, and the ends, away from the connecting disc, of the main supporting rods are connected with the connector. The connectors on the periphery of the connecting disc are connected through main connecting rods, the main connecting rods are fixed to the left sides and the right sides of the connectors, and slings are installed at the bottom ends of the connectors. The connector is connected with a lifting hook of the crane through a main steel wire rope, and the stand column is connected with the main supporting rod through an inclined supporting rod. The lifting appliance structure can be expanded to form a plurality of annular multi-lifting-point lifting appliances suitable for lifting and mounting spherical tank type structural parts with different sizes and types, so that the lifting and mounting difficulty of the spherical tank type structural parts is reduced, and the lifting deformation and the mounting precision are favorably controlled.

    本发明涉及吊具工装技术领域,具体公开了一种环形多吊点吊具结构,包括立柱;所述立柱垂直固定在连接盘上,立柱的顶端设置有吊具吊耳,吊具吊耳上安装有用于移动该吊具的索具吊运卸扣;所述连接盘上环形阵列设置有多个主撑杆,主撑杆远离连接盘的一端与连接器连接;所述连接盘外围的多个连接器之间通过主连接杆连接,主连接杆固定在连接器的左右两侧,连接器的底端安装有吊索;所述连接器与起重机的吊钩之间通过主钢丝绳连接,立柱与主撑杆之间通过斜撑杆连接。该吊具结构可扩展形成多个适用于不同大小和类型的球罐型结构件的吊运、安装的环形多吊点吊具,降低了球罐型结构件的吊运、安装难度,有利于控制吊运变形和安装精度。
