Abstract

The invention discloses a main lifting lug of a booster station project and a construction process for the main lifting lug. The main lifting lug comprises a base structure plate, wherein a first embedded slot is formed in the base structure plate in the vertical direction; a lifting lug reinforcing plate is arranged in the first embedded slot; a second embedded slot is formed in the lifting lug reinforcing plate in the horizontal direction, a shear plate is arranged in the second embedded slot, the two ends of the shear plate are separately equipped with lifting rope locking plates; four lifting lug shafts which are symmetrically arranged with respect to the shear plate are symmetrically arranged between the lifting rope locking plates and the lifting lug reinforcing plate; the back surface of the base structure plate is equipped with a terminal wing plate structure plate which abuts against the lifting lug reinforcing plate; the main lifting lug is stable in structure, and can bear relatively great tensile force, so that establishment of a sea booster station is convenient; welding deformation amount is controlled through the construction process, so that the structure is more stable; and stress is removed through cooling and ultrasonic means, so that internal damages are avoided, the service life is prolonged, flaw detection and repair are timely performed, and welding quality is improved.

Description

Technical field [0001] The invention relates to the technical field of sea booster stations, and more specifically, it relates to a main lifting lug of a booster station project and its construction technology. Background technique [0002] Wind power generation is currently the mainstream industry of clean energy in the international community. It has limited social and environmental benefits and is of great significance to the promotion of the development of renewable energy in my country. The sea uplift station is one of the components of the offshore wind farm, and the sea uplift station is The transfer station and key hub for centralized boosting and transmission of wind farm power, the sea booster station gathers the most core electrical equipment of the entire wind farm, and is also the core of manual daily maintenance and operation of the booster station. [0003] The service life of the sea booster station is 50 years, the anti-corrosion design life is no less than 25 years...
