Description

Technical Field

[0001] The present application belongs to the technical field of offshore power generation equipment manufacturing, and specifically relates to a blade laying tool and a construction vessel. Background Art

[0002] When offshore wind turbines are installed in a split style, there are two types of blade hoisting: impeller hoisting and single blade hoisting. For large units, single blade hoisting is generally used due to the length of the blades. During the single blade hoisting process, the blades need to be placed upside down on the wind power installation ship, and then the transport tooling is removed and the blade fixture is installed before the blades can be hoisted up and docked with the wind turbine hub. As the blades become larger, the distance between the two resting points of the blades is large, and they cannot be placed after being placed upside down on the wind turbine platform. Therefore, blade resting tooling is required. The blade resting tooling is located on the outside of the ship and needs to be disassembled to the ship deck during towing, which makes the construction cumbersome. Utility Model Content
