Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe pile turning equipment, in particular to a rotatable steel pipe pile turner. Background Technique

[0002] With the large-scale development of offshore projects such as offshore wind power, the application of steel pipe piles has become increasingly popular. The steel pipe piles for offshore projects are driven into the deep seabed. As the basic support for offshore projects, their length is generally more than seventy or eighty meters. Steel pipe piles are generally manufactured into finished products in land steel pipe pile processing plants and are transported horizontally by transport barges to the offshore construction site for pile driving. For the pile driving construction of steel pipe piles, the steel pipe piles lying horizontally on the barge need to be lifted and erected first, and the posture of the steel pipe piles is adjusted to the vertical state before driving them into the deep seabed. Therefore, the work of adjusting the steel pipe piles from the horizontal lying state to the vertical state is particularly important.

[0003] At present, most projects use the method of welding turning lugs to turn the steel pipe piles. First, the steel pipe piles are placed on the steel pipe pile brackets on the side of the transport ship. The steel pipe pile brackets are generally divided into a front fixed bracket and a rear rotating bracket. Lugs are welded at the front end of the steel pipe pile, and the steel pipe pile is lifted. The rear rotating bracket rotates along the vertical plane following the steel pipe pile. Due to the bumps during the lifting process, the rear rotating bracket is prone to rotate on the horizontal plane, resulting in damage to the rotating bracket.

[0004] Therefore, a rotatable steel pipe pile turner is provided to solve the above problems. Content of the Utility Model
