The invention relates to the technical field of building construction, and discloses a safe hoisting device for building construction. The safe hoisting device comprises a hoisting arm, wherein the lower end of the hoisting arm is fixedly connected with a hoisting box; the middle of the hoisting box is in sliding connection with a first pulley; the bottom end of the first pulley is fixedly connected with a sliding block; the left end and the right end of the first pulley are fixedly connected with two first sliding rails; and the left sides and the right sides of the two first sliding rails are in sliding connection with two second pulley blocks. According to the safe hoisting device, a protection mechanism is introduced, and the auxiliary pulley effectively decomposes the pulling force of a traction rope so as to achieve the effect of protecting the traction rope; and meanwhile, through cooperative arrangement of an electromagnet, a conducting strip and the sliding block, the gravity borne by a hoisted object is estimated, the effect of reasonably adjusting the length of the hoisting arm to enable the hoisted object to move within the safe construction radius all the time is achieved, and the problems that in the prior art, due to the fact that the weight of the object is unknown, the hoisting arm exceeds the maximum load torque, and consequently safety accidents are caused are solved.
本发明涉及建筑施工技术领域,且公开了一种建筑施工用安全吊装装置,包括吊臂,所述吊臂的下端固定连接有吊箱,所述吊箱的中端滑动连接有第一滑轮,所述第一滑轮的底端固定连接有滑块,所述第一滑轮的左右两端均固定连接有两个第一滑轨,两个所述第一滑轨的左右两侧均滑动连接有两个第二滑轮组。本发明通过引入保护机构,辅助滑轮有效分解牵引绳的拉力进而达到牵引绳索进行保护的效果,同时通过电磁铁、导电片、滑块之间的配合设置实现将被吊物体所受重力的预估,达到合理调节吊臂长度使得被吊物体始终保持在安全施工半径内进行移动的效果,解决了现有技术因物重未知造成的吊臂超出最大负荷力矩造成的安全事故的问题。
