The utility model relates to a rotary operation platform, which belongs to the technical field of building construction, and mainly solves the problem that an existing steel tube scaffold is unsuitable for construction of reinforced concrete structures with inclination angle changes such as egg-shaped vertical surfaces and the like. The rotary operation platform is mainly characterized in that the rotary operation platform comprises a central tower, a rotary support, a horizontal truss, an inclined truss, support rollers and an annular rail, the central tower is vertically mounted at the central position of a reinforced concrete structure with a circular planar face, the rotary support includes an annular ring beam and a rotary arm, the annular ring beam can be fixed onto the central tower, the rotary arm is clamped onto the annular ring beam by the aid of rollers mounted in three different directions, the horizontal truss fixedly connected with the rotary arm is connected with the inclined truss by the aid of a connecting lead screw, and the support rollers mounted at the lower end of the inclined truss are supported by the annular rail. The rotary operation platform has the advantages of less needed materials, and simple, convenient and rapid assembly and disassembly operations, and is mainly used for construction operation of the structures of various different sizes and shapes.
