Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Embodiment
As shown in Figure 1-2, a kind of flange of wind power generation tower barrel platform for lining, it is for the splicing of wind-driven generator tower and tower drum flange, and platform for lining includes platform body 1, pressing plate 3, cushion block 5 and bolt 7, wherein:
Described platform body 1 includes inner ring 1-3, outer shroud 1-4 and spoke 1-2, described inner ring and outer shroud are concentric ring, the center of circle of concentric ring is center of circle P, described spoke 1-2 is fixed between inner ring and outer shroud, described spoke 1-2 is provided with backing plate 1-1, described backing plate 1-1 is provided with 1# bolt hole 8, described backing plate flatness≤0.5mm;
Described pressing plate 3 one end is placed on described tower drum flange, and the described pressing plate other end is placed on described cushion block 5, is provided with 2# bolt hole 10 in the middle part of described pressing plate, and described cushion block 5 is placed on backing plate 1-1;
Backing plate 1-1 and pressing plate 3 are fixed by 1# bolt hole 8 and 2# bolt hole 10 by described bolt 7.
Understand for convenience of everybody, cushion block height H processes according to flange thickness T adjustment.Bolt 7 can but be not limited to M16 bolt; 2# bolt hole 10 can but be not limited to φ 20mm.Pad 6 can be established between bolt 7 and pressing plate 3.Above-mentioned cushion block 5 generally selects hard cushion block, and cushion block 5 is parallels preferably.Above-mentioned backing plate 1-1 generally selects hard backing plate, as steel plate.
As shown in Figure 1, during actual use, platform body 1 is fixed on the ground by support 9.Flange 2 is placed between backing plate 1-1 and pressing plate 3, and tower cylinder cylindrical shell 4 is placed in above flange lug boss 2-1.
In splicing, because flange is placed on splicing platform, the backing plate flatness≤0.5mm on splicing platform; And flange is fixed by pressing plate, backing plate and bolt, so flange undersurface flatness also ensures to meet the requirements.When use procedure, operative employee, just without the need to considering flange undersurface flatness problems with respect, only needs to consider whether cylindrical shell and flange lug boss have had misalignment just.If there is misalignment, workman also can use pressing plate and auxiliary mould is put, and as taper pin etc., corrects and location.When being welded and fixed flange and cylindrical shell, operative employee can at center circle region operation, as measured flange and cylindrical shell counterpart misalignment and observe, easy to operate.
Use platform for lining described in the utility model, through pulse planometer actual measurement planeness of flange, wind tower tower flanges flatness can be less than 2mm.
For providing better support effect, the preferred 6-10 of number of above-mentioned spoke 1-2.As shown in Figure 1,8 spoke 1-2 circumferential arrangement are between inner ring and outer shroud, and the central point of circumferential arrangement is center of circle P.
Implement in use procedure, tower cylinder cylindrical shell and flange diameter can change.For adapting to tower cylinder, the flange splicing of different size, inventor proposes following improvement opportunity scheme: be positioned at the described 1# bolt hole 8 circumferentially array arrangement on backing plate 1-1, the central point of described circumference array arrangement is center of circle P, that is: the central point of circumference array arrangement is overlapping with the described inner ring center of circle.As shown in Figure 1, each backing plate 1-1 can but be not limited to establish 9 1# bolts hole 8.
Now, each backing plate 1-1 can distribute and be in the 1# bolt hole 8 of different-diameter scope, for the tower cylinder of different size and flange splicing, applied widely, if diameter is between the flange of 2750mm ~ 4300mm and cylindrical shell.
The utility model is not limited to above-described embodiment, and the technical scheme that all employings are equal to replacement or equivalence replacement formation all belongs to the claimed scope of the utility model.
