The invention discloses a gravity center self-adjusting type blade air assembly lifting appliance which comprises a dual self-rotating mechanism. The dual self-rotating mechanism comprises a large-range rotating arm, a small-range rotating arm is hinged to the large-range rotating arm, and a rotating arm fixing base is hinged to the small-range rotating arm. A swing arm assembly is arranged at the top end of a tray, and clamping assemblies are symmetrically arranged at two ends of the tray. The swing arm assembly comprises a swing arm support and a swing arm hydraulic cylinder. Each clamping assembly comprises a clamp body, wherein a rotary clamping arm and a clamping hydraulic cylinder are hinged to the clamp body, the clamping hydraulic cylinder is hinged to the rotary clamping arm, an upper clamp blade shape follow-up protection module is fixedly connected to the rotary clamping arm, and a lower clamp blade shape follow-up protection module is fixedly connected to the clamp body. The device solves the problem that the gravity center changes during offshore high-altitude large-rated-load single-blade assembly, operation can be carried out in a limited hoisting space, a damaged blade can be maintained and replaced, and the working condition requirement of offshore installation of a wind turbine generator is met.
Description
technical field [0001] The invention relates to the field of hoisting, in particular to a center-of-gravity self-adjusting blade pairing hanger in the air. Background technique [0002] Offshore wind power plant is a new type of power plant that utilizes offshore wind resources to generate electricity. The average annual growth rate of the cumulative installed capacity of wind power in the world has been close to 30.00% since the beginning of the 21st century. Wind power technology is becoming more and more mature. , resulting in larger, heavier blades and higher pairing heights, and increased difficulty in hoisting single blades due to factors such as the placement of the installation ship and the rotation direction of the boom. [0003] The center of gravity of the high-altitude and large-load single-blade group at sea is constantly changing. The existing spreader cannot meet the lifting conditions of the current working conditions due to space limitations and functional s...
