Abstract
The invention discloses a suction cylinder cover mounting method, and relates to the technical field of offshore wind power manufacturing. The method specifically comprises the following steps: S1, cylinder cover manufacturing: manufacturing a top plate, scribing the top plate, butting a central cylinder with the top plate, and welding a triangular plate at the bottom of the top plate; and S2, horizontal installation is adopted for installation of the cylinder cover and the cylinder body, specifically, preparation before hoisting, cylinder cover hoisting, cylinder cover installation, rotation of a roller frame at the bottom of the cylinder body, simultaneous welding of circular seams, and cylinder cover installation completion. The device has the advantages that the cylinder cover and the cylinder body are horizontally mounted, the hoisting construction difficulty is reduced, during mounting, the bisectrix is firstly marked on the cylinder cover, the cylinder cover is welded with the cylinder body by taking the bisectrix as a reference, the triangular plate welded on the cylinder cover is firstly inserted into the cylinder body, and the triangular plate can perform internal support on the top of the horizontal cylinder body, so that the cylinder body with large diameter and thin cylinder wall is prevented from downwarping and deforming; installation is easier, the installation precision of the barrel cover and the barrel body is ensured, and the manufacturing quality of the suction barrel is improved.
Description
technical field [0001] The invention relates to the technical field of offshore wind power manufacturing, in particular to a method for installing a suction cylinder cover. Background technique [0002] In recent years, the state has increased its support for offshore wind power projects, and my country's wind power industry is in a stage of vigorous development. In 2020, the country's first suction tube jacket was successfully installed offshore, marking the birth of a new type of offshore wind power jacket structure - the suction tube jacket. The application of suction cylinder technology in offshore construction has the characteristics of convenient installation, short cycle, convenient dismantling, no noise, no piling vibration, etc. It will effectively reduce the pollution of the marine environment during engineering construction, protect the ecological environment, and make positive contributions to the practice of green development strategies. With the improvement of...
