The invention relates to an umbrella-shaped hoisting device for hoisting a hollow cylinder in subway construction. The umbrella-shaped hoisting device comprises a main rod, a stretching component, a moving component and force holding components, wherein the main rod has a hollow structure, the stretching component penetrates through the interior of the main rod in a hollow mode and then is connected with the moving component, the moving component is connected to the main rod in a sleeved mode, the force holding components are hinged to the moving component and the bottom end of the main rod respectively, and the at least two force holding components are symmetrically arranged around the main rod. According to the scheme, the opening and closing degree of the force holding rod member is controlled through the lifting force, so that the technical problem that the existing pipe pile hoisting tool cannot hoist hollow main body structures with different pipe diameters is solved; and by arranging a variety of force holding arms, the hollow main body structure is reinforced through the arranged multiple sets of supporting so as to effectively guarantee the non-deformation of the hollow main body structure.
本发明涉及一种用于地铁施工中吊装中空柱体的伞形吊装装置,包括主杆,拉伸部件,运动部件,持力部件,所述主杆为中空结构,所述拉伸部件从主杆内空下穿之后与运动部件相连接,所述运动部件套接在主杆上,所述持力部件分别与运动部件和主杆底端铰接,所述持力部件包括至少两个,所述持力部件围绕主杆对称设置;上述方案通过提升力控制持力杆件的张合度,解决了现有管桩吊装工装不能起吊不同管径的中空主体结构的技术问题,同时通过设置的多种持力臂如同多组支撑对中空主体结构进行了加固,有效保证了中空主体结构的不变形。
