Problems solved by technology
[0003] At present, the spud boots of windmill installation ships are mainly connected to the spud legs by welding. For some marine steels, the weldability of steel is poor, and cracks are prone to occur in the weld area of ultra-thick plates, which seriously affects the spud legs and spud legs. Spud shoe connection performance

Embodiment Construction
[0019] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.
[0020] The invention shows a method for connecting the spud legs and spud shoes of a windmill installation ship. The part where the spud legs (1) are screwed into the spud cans (3) is tapped with external threads. Since the spud legs (1) are tubular and have a wall thickness of Therefore, when tapping the external thread of the pile leg (1), it is necessary to fully consider that the thread will not affect the strength of the pile leg (1). The size should be determined according to the radius of the pile leg (1), and tap the internal thread in the pile shoe (3).
[0021] A special rotary table for manufacturing the lifting spud can (3), the r...

The invention relates to a connecting method of a spud leg and a pile shoe of a windmill mounting ship. The method comprises the following steps: 1) tapping external threads on the part screwed in the pile shoe of the spud leg, and tapping internal threads in the pile shoe, wherein the spud leg is tubular and the wall thickness of the spud leg is 100m,; 2) manufacturing a special rotary work table for lifting the pile shoe, wherein the rotary work table is composed of a rotary rotor and a base, the base is fixed, the rotary rotor rotates, and the rotary rotor is in threaded connection with the base; 3) arranging the pile shoe on the rotary work table to realize the threaded connection of the spud leg and the pile shoe; and 4) welding the interface of the pile shoe and the spud leg after realizing the threaded connection of the spud leg and the pile shoe to reinforce the connecting quality and guarantee the connecting property of the spud leg and the pile shoe. The connecting method provided by the invention has the advantages of realizing the position adjustment of the pile shoe of the windmill mounting ship during the building process, being convenient for installation, and the like.
Description
technical field [0001] The invention relates to the technical field of manufacturing marine engineering equipment, in particular to a method for connecting a spud leg and a spud shoe of a windmill installation ship. Background technique [0002] In recent years, with the increasingly prominent environmental protection issues and the shortage of energy supply, wind energy has become a clean energy. Renewable new energy has been paid more and more attention, and wind power has gradually become one of the largest and most mature power generation methods in new energy technologies. The transportation and installation of offshore wind turbines is an important step in the construction of wind farms, so windmill installation ships for the installation and maintenance of offshore wind turbines have emerged as the times require. The working principle of the windmill installation ship is: the hull extends the legs into the seabed through the lifting system. When the legs reach the se...
