A frame beam 2 is connected between two adjacent frame columns 1 in the same row, and a frame beam 2 is connected between two adjacent frame columns 1 in the same column. Preferably, the plurality of frame beams 2 are all located in the same horizontal plane. The frame columns 1 and the frame beams 2 can be connected by welding, and the frame beams 2 and the frame columns 1 are perpendicular to each other. The steel structure protection operation platform is formed by a plurality of frame beams 2 and a plurality of frame columns 1. In this embodiment, the installation sleeve 3 is detachably installed on the frame beam 2, so that the swing arm 4 is convenient to install. Moreover, the swing arm 4 can rotate relative to the installation sleeve 3, and the direction of the swing arm 4 can be adjusted according to actual needs. Then, the swing arm 4 with the adjusted angle is fixed to the installation sleeve 3 by the first connecting member 5. Finally, the protective member 6 is installed between two adjacent swing arms 4, which improves the flexibility of the installation of the protective member 6 and further improves the safety protection effect of the high-altitude operation personnel.
