The invention discloses a four-section type tower crane attachment frame and a mounting method thereof, and belongs to the technical field of engineering machinery, the four-section type tower crane attachment frame comprises a first half frame, a second half frame and two connecting beams, the two connecting beams connect the first half frame and the second half frame together through a fastening mechanism, hoops are arranged at the joints of the first half frame and the second half frame with a tower body main chord, and the first half frame and the second half frame are connected through a fastening mechanism. Hoops are respectively connected with the first half frame, the second half frame and the tower body main chord, so that the tower body main chord and the four-section type tower crane attachment frame are connected into a whole; the diagonal diagonal brace rods are connected with the two hoops at the diagonal positions of the attachment frame; the attachment frames and the tower body main chords are connected into a whole through the pin shafts, the hoops and the diagonal brace rods, the influence of the concentrated force of the attachment frames on the tower body web members is reduced, the stress of the tower body is improved, and therefore the requirements for the strength and rigidity of the tower body are lowered; integrated installation is achieved, the hoisting frequency is reduced, and installation time is saved; and a four-section assembly design is adopted, and the maximum size meets the transportation requirement.
本发明公开了一种四段式塔机附着框及其安装方法,属于工程机械技术领域,包括第一半框、第二半框和两个连接梁,两个连接梁通过紧固机构将第一半框和第二半框连接在一起,在第一半框、第二半框与塔身主弦的连接处设有抱箍,抱箍分别连接所述第一半框、第二半框与所述塔身主弦,使塔身主弦和四段式塔机附着框连接为整体;还包括对角斜撑杆,连接附着框对角处的两个抱箍;本发明通过销轴、抱箍、对角斜撑杆将附着框和塔身主弦联接为整体,减少附着框集中力对塔身腹杆的影响,改善塔身受力,从而降低对塔身强度、刚度的要求;集成化安装,减少吊装次数,节省安装时间;采用四段式装配设计,最大尺寸满足运输要求。
