The invention relates to an integral lifting or hoisting technology of a large platform, in particular to a limiting safety device for hoisting and falling of a steel ring beam and a hoisting method of the limiting safety device. Comprising a mounting plate (1), high-strength bolt connecting holes (2) and stiffening plates (3), the high-strength bolt connecting holes (2) are formed in the mounting plate (1), and the stiffening plates (3) are arranged between the high-strength bolt connecting holes (2); and the mounting macadam (1) is mounted on an upper flange plate of the ring beam bracket through the high-strength bolt connecting holes (2) and connecting bolts. According to the limiting safety device, bolt connection is adopted, and the limiting safety device is convenient to disassemble and can be recycled; after installation is completed, the remaining webs in the ring beam and the high-strength bolts on the lower flange are removed; at the moment, the mounting macadam of the safety device and the steel column bracket play a role in lap joint, a certain self-weight load of the structure can be borne, instantaneous impact force generated on the lifting crane after bolts in the platform ring beam are completely dismantled is avoided, and therefore the effect of ensuring the safety of operators below is achieved.

    本发明涉及大型平台的整体提升或吊装技术,是一种用于钢环梁吊装落位的限位保险装置及其吊装方法;包括安装玛板(1)、高强螺栓连接孔(2)、加劲板(3),在安装玛板(1)上开设高强螺栓连接孔(2)并在高强螺栓连接孔(2)之间设置加劲板(3);安装玛板(1)通过高强螺栓连接孔(2)及连接螺栓而安装在环梁牛腿的上翼缘板上。本发明所提出的限位保险装置,采用螺栓连接,拆卸方便,可循环重复利用;安装完成后,拆除环梁内剩余腹板及下翼缘高强螺栓;此时保险装置的安装玛板与钢柱牛腿起到搭接作用,能够承担结构一定的自重荷载,避免了平台环梁内螺栓全部拆除后对升降吊机产生的瞬时冲击力,从而达到了确保下方操作人员安全的效果。
