The invention relates to an offshore oil drilling platform, in particular to a column type ocean platform crane. The lower end of a samson post of the column type ocean platform crane is connected with a pedestal; a rotary table sleeves the pedestal and is meshed with the pedestal by a gear; the rotary table can freely rotate around the pedestal; a lower bearing is mounted between the samson post and the rotary table; a portal sleeves the outer side of the samson post; an upper bearing is mounted between the samson post and the inside of the upper end of the portal; the lower end of the portal is connected to the rotary table by a pin shaft; a mechanical room and a control room are arranged on the rotary table; and the rotary table is connected with a cantilever crane. The column type ocean platform crane has the advantages that the safety factor is high; the bearing and wind loading capabilities are strong; the use requirement can be met under a severe working condition; the load is large; the speed is rapid; the efficiency is high; the continuous and frequent operation can be realized; a common hand tool is used for completing the examination and maintenance operation of a rotation supporting system; the maintainability and corrosion resistance are high; the structure is simple; the failure rate is low; the installation is convenient; and the work of carrying, installing and disassembling apparatuses and the like can be conveniently carried out within a range.
