The large-span steel structure high-altitude hoisting auxiliary device comprises a hoisting block and a cylindrical connecting sleeve, a plurality of hoisting ropes are fixedly connected to the middle position of the upper end face of the hoisting block, and two symmetrically-distributed fixed pulleys are fixedly connected to the bottom of the hoisting block; the two symmetrical positions of the upper end of the connecting sleeve are each fixedly connected with a connecting rope, the inner sleeve wall of the connecting sleeve is slidably connected with a connecting column, and the ends, away from the connecting sleeve, of the two connecting ropes are wound around the two fixed pulleys and jointly and fixedly connected with the top end of the connecting column. The hoisting device can automatically adjust the relative position of the connecting column and the connecting sleeve according to steel structures of different lengths, so that the two ends and the center of each steel structure are bound and hoisted through ropes, the high-altitude hoisting stability of the large-span steel structure is improved, meanwhile, the steel structures can be reversely pushed to rotate in the air by means of wind power generated by the pushing fan, and the hoisting efficiency is improved. And the steel structure can be conveniently hoisted, placed and installed, and hoisting and building construction efficiency is improved.
本发明公开了大跨度钢结构高空吊装辅助装置,包括吊块和圆柱型的连接套筒,所述吊块上端面中间位置固定连接有多根吊绳,所述吊块的底部固定连接有两根对称分布的定滑轮,所述连接套筒的上端两个对称位置均固定连接有一根连接绳,所述连接套筒内筒壁滑动连接有连接柱,两根所述连接绳远离连接套筒的一端分别绕设经过两个定滑轮且共同与连接柱的顶端固定连接。本发明中吊装装置可以根据不同长度的钢结构能够自行调节连接柱与连接套筒的相对位置,使钢结构两端和中心均有绳捆绑和吊拉,提高了大跨度钢结构的的高空吊装稳定性,同时可借助推动扇产生的风力反推钢结构在空中转动,方便钢结构下吊放置和安装,提升了吊装和建筑施工效率。
