Telescopic special-shaped steel structure transportation supporting tool

The invention discloses a telescopic special-shaped steel structure transportation supporting tool. The problems that in the prior art, transportation transferring equipment is damaged due to uneven stress in the transportation process of a special-shaped steel structure, and the special-shaped steel structure has the potential safety hazard of slippage are solved. The device comprises a #-shaped frame structure with the adjustable width and a supporting frame arranged on the frame structure and used for supporting the special-shaped steel structure. The four supporting frames are arranged at the four corners of the frame structure respectively. The device can be telescopically adjusted along with different sizes of special-shaped reticulated shell steel structures, is convenient to disassemble and assemble, can be repeatedly used and is economical and universal, and the special-shaped reticulated shell steel structures are in contact with a vehicle plate of a vehicle or equipment through a frame structure du
