Abstract
The utility model relates to a vibration reduction type wind-electricity stepped drum. The traditional wind-electricity stepped drum is not suitable for use under conditions of requiring large bearing capacity and good section stability and using in awful weather. The vibration reduction type wind-electricity stepped drum comprises a fixing flange (1), wherein the fixing flange is connected with a stepped drum body which is connected with a metal rubber plate (2), the metal rubber plate is connected with a generator fixing plate (3), the stepped drum body comprises a drum body lower section (4) which is connected with a stepped drum middle section (6) through a connecting flange (5), the stepped drum middle section is connected with a stepped drum upper section (7) through a connecting flange, and the inner wall of the stepped drum body is welded with 6 pairs of uniformly distributed reinforced rib plates (8). The vibration reduction type wind-electricity stepped drum is used as various wind power generation mechanical structures, especially wind power generation units under conditions of inshore, mountains, remote and border areas, and awful weather, and supporting devices of large units requiring large bearing capacity and good section stability.
Description
Technical field:
The utility model relates to a kind of shock-decreasing type wind-power tower.
Background technique:
The mechanical structure of various wind-power electricity generations; especially the wind power generating set under coastal, mountain area and outlying district and the weather mal-condition; the requirement bearing capacity is big, the large-scale unit of cross section good stability, needs the shock-decreasing type wind-power tower especially, normally moves to protect various mechanical components.
Summary of the invention:
It is little that the purpose of this utility model provides a kind of operational shock, the shock-decreasing type wind-power tower that noise is little.
Above-mentioned purpose realizes by following technological scheme:
The shock-decreasing type wind-power tower, its composition comprises: fastening flange, described fastening flange connect tower tube cylindrical shell, and described tower tube cylindrical shell connects the metal-rubber plate, and described metal-rubber plate connects generator fixing plate.
Described shock-decreasing type wind-power tower, described tower tube cylindrical shell comprises the cylindrical shell hypomere, described tower tube hypomere connects tower tube stage casing by adpting flange, and described tower tube stage casing connects tower tube epimere by adpting flange, and described tower tube cylinder inboard wall is welded with 6 pairs of equally distributed reinforcement gussets.
Described shock-decreasing type wind-power tower, described tower tube hypomere, tower tube stage casing, tower tube epimere are welded into by 8～10 shell rings respectively, and the inside and outside surface of described tower tube cylindrical shell comprises fluorine carbon lacquer coating.
Described shock-decreasing type wind-power tower, described tower tube inwall comprises the damping wire casing.
The beneficial effects of the utility model:
1. the utility model has increased rigidity by the flange connection; guaranteed the wind resistance corrosion resistance by the metal-rubber plate; can satisfy user's different demands; the mechanical structure that can be widely used in various wind-power electricity generations; especially the wind power generating set under coastal, mountain area and outlying district and the weather mal-condition and require that bearing capacity is big, the large-scale unit of cross section good stability; need the shock-decreasing type wind-power tower especially, normally move to protect various mechanical components.Through a large amount of practical proofs, because shock-damping structure is arranged, make vibrations and noise, reduce 35% than common wind-power tower.

With processed finished products before the weldering of all flanges, behind flange and the adjacent shell ring assembly welding, again with other shell ring assembly weldings, postwelding does not need to process during making.By scientific and reasonable arrangement operation, strengthen the operation procedure inspection simultaneously, through flame school shape, can produce the qualified tower tube that meets design requirement fully behind the assembly welding, so not only reduce manufacturing cost, and shortened manufacturing cycle.Flow is as follows:
The preparation of tower tube material, (thickness of slab is the steel plate of 12～28mm) → be UT visits interlayer check → blanking → cutting shell ring bevel for welding → polishing groove face → carry out shell ring die mould → group and stands on roller plate machine → welding of longitudinal seam → cleaning shell ring weld bond → do UT spy weld inspection → each shell ring group to found → use Lincoln weld girth weld → flange, (forging finished product) welds → is RT with the head and the tail shell ring and visit weld inspection → welding reinforcement gusset → welding line trough floor → every section cylindrical shell weld cleaning → cylindrical shell application → installation damping wire casing → installation buffer dynamo fixed plate.
Parameter at each operation stage is: require the upper flange planeness≤0.5mm of whole tower tube, middle planeness of flange≤1mm, lower flange planeness≤1.5mm; Flange distortion trend does not allow to turn up, and turns in only allowing, and amount of deformation is in 0.5mm, and the coaxality≤3mm of every section tower tube.Card model size should be more than 1.5m in curved, upper and lower mouthful of shell ring and model gap≤1.5mm, guarantee to twist behind the shell ring die mould, shell ring two ends longitudinal joint joint steel plate alignment tolerance≤0.5mm, poor≤the 2mm of the each point length of tower tube, flange is to the perpendicularity of cylindrical shell center line, the coaxality of two end flange, its relative difference≤3mm.
