[0018] The application is further described in detail below in combination with the drawings and specific implementation:

[0019] As Figures 1-4 ​The illustrated welding-free quick-mounting and dismounting conical steel column auxiliary installation device comprises a sleeve beam 1, an operation platform 2 and a protective fence 3; the sleeve beam 1 comprises two arc-shaped beams 11; the two arc-shaped beams 11 are connected at the head and tail to embrace the conical steel column 4; the operation platform 2 is arranged on the outer side of the sleeve beam 1 along the circumference of the sleeve beam 1; the inner side of the operation platform 2 is connected with the sleeve beam 1, and the outer side of the operation platform 2 is a cantilever end; the protective fence 3 is arranged on the outer side of the operation platform 2 along the circumference of the sleeve beam 1.

[0020] The operation platform 2 comprises six radial beams 21 arranged along the circumference of the sleeve beam 1 and sub-beams 22 connected between adjacent radial beams 21. In the embodiment, two sub-beams 22 are arranged between two adjacent radial beams 21 along the length direction of the radial beam 21. The length direction of each radial beam 21 is arranged along the radial direction of the sleeve beam 1. The six radial beams 21 and the plurality of sub-beams 22 are arranged along the circumference of the sleeve beam 1 to form an eight trigram-shaped platform support framework, and the operation platform 2 further comprises a steel plate 23 laid on the platform support framework. The sub-beams 22 are connected with the radial beams 21 through bolts, and the steel plate 23 can also be connected with the platform support framework through bolts, facilitating subsequent dismounting. The steel plate 23 can adopt six fan-shaped plates which are laid on the platform support framework in turn.

[0021] The protective fence 3 comprises six vertical poles arranged along the circumference of the sleeve beam 1 and horizontal poles connected between adjacent vertical poles; the bottom of the vertical pole is connected with the radial beam 21. The radial beam 21 serves as a force bearing member of the vertical pole.

[0022] The ends of the two arc-shaped beams 11 are provided with ear plates, the ear plates of the ends of the two arc-shaped beams 11 are connected in opposition and connected through bolts. In some embodiments, the sleeve beam 1 can adopt more arc-shaped beams 11 connected in turn at the head and tail. The two arc-shaped beams 11 in the embodiment are clamped at the opposite sides of the conical steel column 4, and are connected through bolts after being folded, so that the sleeve beam 1 embraces the periphery of the conical steel column 4. Since the diameter of the conical steel column 4 gradually increases from top to bottom, the sleeve beam 1 will not drop after embracing the periphery of the conical steel column 4, and welding is not needed, thus simplifying the installation and not needing cutting during subsequent dismounting, and the conical steel column 4 itself will not be damaged.
