The utility model relates to a marine wind power foundation pile lifts by crane turns over a ware, the articulated mechanism bilateral symmetry is provided with two sets ofly.

The utility model relates to an offshore wind power foundation pile lifts by crane and turns over a ware, hinge mechanism includes and installs in the last picture peg of roll-over stand, and the symmetry is fixed with two lower otic placodes on the deck, and goes up the picture peg and insert and arrange in between two lower otic placodes, and round pin axle cross-under between last picture peg and lower otic placode, and the epaxial cover of round pin is equipped with the axle sleeve, is provided with sealed oil pocket between axle sleeve and the round pin axle, and the axle sleeve inlays and arranges in last picture peg, it is provided with an axial oil duct to sell epaxial its length direction, the interior many radial oil ducts that radially are provided with of round pin of interior edge of round pin, axial oil duct and radial oil duct.

The utility model relates to an offshore wind power foundation pile lifts by crane and turns over a ware, the epaxial cover of round pin is equipped with a plurality of gaskets, the gasket is located picture peg and lower otic placode between.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model has simple integral structure, convenient manufacture and low cost; the pile pipe is limited by the side stop blocks arranged on the two sides of the roll-over stand, so that the stability of the pile pipe is better; the side baffle block is firmer in structural form, and is not easy to break due to collision to influence the service life; meanwhile, the arrangement of the cushion block is more beneficial to providing supporting force for the pile pipe, and the structure is simpler and more reliable; in addition, the design of the oil duct is added, and after lubricating oil or lubricating grease is filled, the pin shaft can be lubricated more, so that excessive abrasion to the pin shaft in the rotating process is avoided, and the service life of the pin shaft is prolonged.
