Description
Technical field
[0001] The present invention relates to the technical field of installation hangers for wind blades, in particular to the technical field of clamping mechanisms for installation hangers for wind blades. Background technique
[0002] At present, as people pay more attention to environmental protection, the state has issued a series of incentive policies and measures to promote the development of wind power. China has made great progress in the development and utilization of wind energy. The single-unit capacity of wind turbines is also increasing. It has not kept up with the speed of industry development, especially the installation equipment of the impeller, which in turn restricts the large-scale fan. The diameter of the impeller of a fan with a single unit capacity of 3.5MW or more has exceeded 140m. The general installation of the impeller requires larger installation equipment and construction sites. At the same time, as the diameter of the impeller increases,...
Examples
Embodiment approach
[0067] The cylinder 021 of the pitch mechanism 2 is hinged with the main beam 1 and the second link 023 to drive the four-link mechanism composed of the rocker arm 024, the first link 022, the second link 023 and the main beam 1 as a rocker. The action changes the angle between the rocker arm 024 and the main beam 1. In order to maintain the overall longitudinal stability, the spreader makes the longitudinal center of gravity of the blade 01 automatically coincide with the lifting point on the top of the rocker 024 to a vertical line. When the cylinder 021 is retracted to the shortest process, the whole machine will slow down under the action of the center of gravity. Slowly longitudinally rotate clockwise to +32°; when the cylinder 021 is extended to the longest, the whole machine will slowly rotate longitudinally and counterclockwise to -62° under the action of the center of gravity.
