The invention provides a safe hoisting device for building construction, and belongs to the technical field of hoisting. Comprising a plurality of sets of cross arms located on the two sides and used for hoisting hollow steel pipes, limiting assemblies used for fixing the ends of the hollow steel pipes are further installed on the multiple sets of cross arms, and each limiting assembly comprises a limiting rod with one end extending into the corresponding hollow steel pipe and a limiting spring connected between one end of the limiting rod and the corresponding cross arm; a pull ring connected with the lifting hook through a lifting ring is also arranged above the hollow steel pipe; the pull ring is connected with the plurality of limiting rods through a plurality of steel cables; the limiting assembly further comprises triangular chucks and multiple sets of extension rods, the sliding blocks are installed on the corresponding triangular chucks in a sliding mode, the multiple sets of cross arms are further provided with cylindrical dampers for slowing down the rotating speed of the corresponding cross arms, and the cylindrical dampers and the limiting rods are arranged in a staggered mode. Through the arrangement of the cross arms, the limiting rods and the like, a series of problems of poor stability, high risk and the like during hollow steel pipe hoisting in the prior art are solved.

    本发明提供一种建筑施工用安全吊装装置,属于吊装技术领域;包括位于两侧并用于吊装空心钢管的多组交叉臂,其中多组所述交叉臂上还安装有用于固定空心钢管端部的限位组件,限位组件包括一端延伸至对应空心钢管内部的限位杆,以及连接在限位杆一端与交叉臂之间的限位弹簧,空心钢管上方还设有通过吊环与吊钩相连接的拉环,拉环与多个限位杆之间通过多个钢缆相连接;限位组件还包括三角卡盘,以及多组延长杆,滑块滑动安装在对应的三角卡盘上,多组交叉臂上还设有减缓对应交叉臂转动速率的柱形阻尼,且柱形阻尼与限位杆呈交错布置。本发明通过交叉臂与限位杆等设置,解决了现有技术中吊装空心钢管时稳定性差、危险性大等系列问题。
