Description

Technical Field

[0001] The invention relates to the technical field of offshore wind power engineering, and in particular to an offshore wind power steel pipe pile lifting and flipping device. Background Art

[0002] Offshore wind power generation makes full use of the advantages of high wind speed, stable wind power and no land occupation on the ocean, and has become a rapidly emerging member of clean energy. Although offshore wind power generation has many advantages over land-based wind power generation, there are many difficulties to overcome in building offshore wind power facilities, the first of which is to build an offshore wind power foundation on the seabed.

[0003] China Authorization Announcement No. CN218114812U discloses an offshore wind power steel pipe pile lifting and flipping device, which belongs to the field of offshore wind power engineering. The offshore wind power steel pipe pile lifting and flipping device includes: a shell; a telescopic assembly, which is slidably arranged on the side of the shell; a driving assembly, which is arranged in the shell, and the driving assembly is transmission-connected with the telescopic assembly, and the driving assembly is used to drive the telescopic assembly; and a lifting lug, which is rotatably arranged at the rear end of the shell. The offshore wind power steel pipe pile lifting and flipping device can automatically complete the separation from the steel pipe pile, without the need for operators to dive underwater for auxiliary operations, thereby improving construction efficiency and reducing the operating risks of construction personnel. In addition, the lifting lug is in a vertical state during the entire lifting process, and there is no relative movement between the hook and the lifting lug, thereby avoiding unhooking accidents.

Some wind power steel pipes are heavy, and this single internal expansion method is still not stable enough. Therefore, we designed an internal and external fixation method, and then designed an offshore wind power steel pipe pile lifting and flipping device. Summary of the invention
