Description

The method of attachment of windmill vessel spud leg and shoe
Technical field
The present invention relates to the manufacturing technology field of marine engineering equipment, refer in particular to the method for attachment of windmill vessel spud leg and shoe.
Background technology
In recent years, becoming increasingly conspicuous with the nervous wind energy of energy supply as a kind of clean along with environmental issue.Reproducible new forms of energy more and more come into one's own, and wind-power electricity generation becomes one of generation mode on the largest scale and the most ripe in new energy technology gradually.And therefore the transport of offshore wind turbine and installing as an important step of Construction of Wind Power arises at the historic moment for the windmill vessel of the I&M of offshore wind turbine.The operating principle of windmill vessel is: hull stretches into seabed by jacking system by spud leg, in the time that spud leg arrives seabed, hull can be lifted away to water surface certain distance with carrying hull weight, the interaction by the precipitation such as spud leg or shoe and sea bed ground provides a working platform stably for ocean operation.The important technology feature of windmill vessel ship is to adopt the size relatively large large shoe of independence, and one of significant advantage of bringing is that shoe driving depth is little, ship to plug and unplug a speed fast, mobility is good.The quality of spud leg and shoe switching performance will directly affect the stability of standing energy of hull.
The shoe of windmill vessel at present is mainly connected on spud leg with welding manner, and for some hull steels, the weldability of steel is poor, and easily cracks for the weld metal zone of ultra-thick plate, has had a strong impact on the switching performance of spud leg and shoe.
Summary of the invention
The object of the invention is in order to overcome above deficiency, the method for attachment of the simple windmill vessel spud leg of a kind of method and shoe is provided.
Object of the present invention is achieved through the following technical solutions: the method for attachment of a kind of windmill vessel spud leg and shoe, it is characterized in that, and the method comprises the steps:
1) at the part external threading of spud leg screw-in shoe, described spud leg is that tubulose and wall thickness are 100mm, and tapping thread in shoe;
2) manufacture the Special rotary workbench of lifting shoe, rotary table is made up of rotor and base, and described base is motionless, and rotor rotates, between described rotor and base for being threaded;
3) shoe is placed on rotary table, realizes being threaded of spud leg and shoe;
4) after realizing being threaded of spud leg and shoe, then, at the interface of shoe and spud leg, weld, the quality that reinforces the connection, guarantees the switching performance of spud leg and shoe.
The caliber size of described shoe is determined according to the radius size of spud leg.
Described base is motionless, when rotor rotates, not only can drive shoe rotation, and being threaded between rotor and base can be converted into upwards feed motion rotatablely moving and reach the effect of lifting shoe.
The pitch of described rotary table is identical with the pitch of shoe, ensures that rotor synchronouss working with shoe, effectively avoided spud leg and shoe between the impact of active force on installation accuracy.
The method that the present invention is with bolts and welding is used in conjunction with, first external threading on spud leg, then tapping thread in shoe, manufacture the rotary table of lifting shoe, shoe is placed on the rotary table identical with shoe pitch, first realize being threaded of spud leg shoe, then adopt the method for welding to reinforce at bolt interface, guarantee the switching performance of spud leg shoe.
The present invention has the following advantages: not only solved in simple welding method welding performance poor, the problem that not prison welding is solid, also for the connection of spud leg and shoe provides new thinking.Adopt method and the thinking of the auxiliary shoe rising of rotary table, can solve the adjustment of windmill vessel shoe position in building course, be convenient to install.
brief description of the drawings:

Fig. 2 is the schematic diagram of rotary table;
Fig. 3 is top view of the present invention;
Number in the figure: 1-spud leg; 2-weld seam; 3-shoe; 4-rotor; 5-base;
detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
The present invention shows the method for attachment of a kind of windmill vessel spud leg and shoe, screw in the part external threading of shoe 3 at spud leg 1, because spud leg 1 is that tubulose, wall thickness are 100mm, so in the time attacking spud leg 1 external screw thread, take into full account that screw thread can not impact the intensity of spud leg 1 self, in the process of manufacture shoe 3, the size of shoe 3 bores should be determined according to the radius size of spud leg 1, and in the interior tapping thread of shoe 3.
The Special rotary workbench of manufacturing lifting shoe 3, rotary table is made up of rotor 4 and base 5, between rotor 4 and base 5 also for being threaded.Its operating principle is: base 5 is motionless, in the time that rotor 4 rotates, not only can drive shoe 3 to rotate, and being threaded between rotor 4 and base 5 can be converted into upwards feed motion rotatablely moving and reach the effect of lifting shoe 3.
Shoe 3 is placed on rotary table, realize being threaded of spud leg 1 and shoe 3, because spud leg 1 is very long, the rotation that realizes spud leg 1 is very difficult, the present invention takes to rotate shoe 3, the fixing method of spud leg 1 screws in spud leg 1 in shoe 3, considers that shoe 3 volumes, quality are also very large, adopts rotary table auxiliary, in order to ensure that rotor synchronouss working with shoe 3, the pitch of rotary table is identical with the pitch of shoe 3.Effectively avoided spud leg 1 and shoe 3 between the impact of active force on installation accuracy.
After realizing being threaded of spud leg 1 and shoe 3, then, at the interface of spud leg 1 and shoe 3, weld, the quality that reinforces the connection, guarantees the switching performance of spud leg and shoe.
The present invention has the following advantages: not only solved in simple welding method welding performance poor, the problem that not prison welding is solid, also for the connection of spud leg and shoe provides new thinking.Adopt method and the thinking of the auxiliary shoe rising of rotary table, can solve the adjustment of windmill vessel shoe position in building course, be convenient to install.
