Embodiment Construction
[0012] The present invention will be further described below in conjunction with drawings and embodiments.
[0013] Such as figure 1 , figure 2 As shown, the present invention includes a large ring bracket 1, a small ring bracket 2, and the inner end 22 of the small ring bracket is embedded in the large ring bracket 1, and the large ring bracket 1 and the small ring bracket 2 are respectively passed through connecting pins on both sides of the embedding place. 3 are hinged into a cross shape, and the main hanger lugs 4 are respectively welded to the outer end 11 of the large ring bracket and the outer end 21 of the small ring bracket. Two stiffener plates 8 are welded between the two sides of the lug plate 4 and the corresponding ring outer ends. The auxiliary lug plate 5 is welded respectively outside the inner end 12 of the large annular support and the inner end 22 of the small annular support. In order to protect the outer wall of the offshore wind turbine tower 9 from...

The invention discloses a device for lifting a tower tube of an offshore wind power generator, comprising a big annular bracket and a small annular bracket, wherein the inner end of the small annular bracket is embedded in the big annular bracket; the big annular bracket and the small annular bracket are respectively articulated into an X-shape through connecting pins at two sides of an embedded position; the outer ends of the big annular bracket and the small annular bracket are respectively fixedly connected with a main lifting lug plate; and the inner ends of the big annular bracket and the small annular bracket are respectively fixedly connected with an assistant lifting lug plate. Two sides of the big annular bracket are respectively provided with a plurality of symmetrical pin holes I; and two sides of the small annular bracket are respectively provided with a plurality of symmetrical pin holes I. The device for lifting the tower tube of the offshore wind power generator has the advantages of simplicity in structure, low cost, convenience for assembly and disassembly, safety and reliability for lifting, precise locating and good universality, effectively guarantees the mounting quality of the tower tube of the offshore wind power generator and is capable of lifting tower-tube-shaped members with different diameters.
Description
technical field [0001] The invention relates to a special hoisting device for cylindrical workpieces, in particular to a tower hoisting device for wind power generators, and belongs to the technical field of hoisting equipment. Background technique [0002] In recent years, wind energy, as the renewable energy with the most commercial potential and vitality, is being developed and utilized in many countries. my country's wind energy reserves are huge, and the amount of wind energy that can be developed is more than one billion kilowatts. Among them, the wind energy reserves that can be developed and utilized at sea are about 750 million kilowatts. The development of offshore wind power will become the trend of wind power generation in coastal areas. The structure of offshore wind turbines is similar to a simple offshore platform, mainly including blades, hubs, nacelles, towers and tower foundations. Tower foundations are generally built on offshore tidal flats. Offshore wind...
