At present, the lifting of single-pile wind turbine blades is generally divided into two ways: lifting and barging, and double auxiliary cranes lifting blades to assist the main crane in clamping. The former requires the blades to be barged to the construction ship before lifting, which has certain restrictions on the deck space and blade size; the latter requires the construction ship to have multiple cranes, and most ships fail to meet this condition. Existing wind turbine blades are too large, resulting in insufficient space on the construction ship. Therefore, the utility model provides a Bailey frame structure for temporary storage of blades during barge. Utility Model Content
