Reversible loading platform, transportation carrier and control method

The invention discloses a reversible object carrying platform, a transportation carrier and a control method, and the reversible object carrying platform comprises a guide rail which extends in a first direction; each bearing part is matched with the guide rail in a positioning manner, and each bearing part is provided with a restraining hole and a positioning assembly; the fork arms are installed in the restraining holes of the bearing parts in a sliding mode, the positioning assemblies independently have the positioning state for limiting the position relation between the fork arms and the corresponding bearing parts and the free state for allowing the fork arms to move relative to the corresponding bearing parts, and when the positioning assemblies are in the positioning state, the fork arms move along with the corresponding bearing parts. According to the brand-new reversing device, the problems that in the prior art, a reversing structure is complex and not easy to operate are effectively solved, reversi
