The invention relates to a portable operation and maintenance crane structure for an offshore wind power base, which comprises a crane main cylinder and a truss-type lifting arm, and the portable operation and maintenance crane structure is characterized in that the lower end of the crane main cylinder is fixedly connected with an offshore wind turbine platform through a fixed connection support; the upper end part of the crane main cylinder is provided with an upper fixed plate and a lower support plate; the front end of the truss-type lifting arm is provided with a fixed hook, and the rear end of the truss-type lifting arm is provided with an upper connecting shaft and a lower connecting shaft; the upper connecting shaft is movably connected with the upper fixed plate and the lower connecting shaft is movably connected with the lower support plate, so that a rotary connecting structure that the truss-type lifting arm moves round the crane main cylinder is formed; the range of activity of the truss-type lifting arm is greater than 180 degree; a plurality of spikes are arranged on the crane main cylinder from top to bottom to form a ladder structure; the lower support plate is fixed on the crane main cylinder in a welding manner; the upper fixed plate is fixedly connected on the crane main cylinder through a bolt to form an easy assembled and disassembled connecting structure. The portable operation and maintenance crane structure provided by the invention has the beneficial effects that the lifting height is high, the coverage area of the lifting arm is wide, the lifting weight is heavy, and the operation and the maintenance are easy.
