Climbing-up type platform device for torsional special-shaped continuous variable cross-section steel tower structures

The invention relates to a climbing-up type platform device for torsional special-shaped continuous variable cross-section steel tower structures. The climbing-up type platform device is formed by splicing multiple units through bolts and oval nuts, and the bolts can slide in grooves in sliding operating platforms to be adapted to the steel tower structures with different cross sections. The number of the units is the same as that of vertical faces of the steel tower structures. The structure of each unit is divided into an upper layer and a lower layer. According to the climbing-up type platform device, components are hinged to be adapted to structure torsion occurring in the platform climbing-up process; a suspension type climbing-up system is matched with a universal pulley, and climbing-up on the special-shaped torsion structures is achieved; and platform plates slide relative to one another to be adapted to variation of special-shaped cross sections of a tower body.
