Portable operation and maintenance crane structure for offshore wind power base

Abstract

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.

Description

technical field [0001] The invention relates to a crane structure, in particular to a convenient operation and maintenance crane structure for offshore wind power foundations, and belongs to the technical field of offshore wind power operation and maintenance equipment. Background technique [0002] The wind turbine foundation operation and maintenance crane structure is a lifting device that lifts the equipment and materials required for offshore wind turbine maintenance from the operation and maintenance ship to the wind turbine platform. [0003] In the prior art, due to the unreasonable structure of the wind turbine foundation operation and maintenance crane, the coverage area is small, and dock workers are often required to carry materials from the deck to the platform. However, when the operation and maintenance ship is docked in the designated area, it is difficult for the staff to transport the operation and maintenance materials from the deck to the platform. The e...
