Abstract
The utility model discloses a nacelle chassis of a wind generating set. The nacelle chassis is divided into a front half section and a back half section, wherein the front half section is a casting part, the back half section is a welding part, and the front half section and the back half section are connected into a whole by a plurality of connecting bolts; and anti-loose sleeves are sleeved on the connecting bolts. The nacelle chassis of the wind generating set is a combined structure with the front casting part and the back welding part. The front half section used for bearing main loads is shaped by adopting integral casting, thus ensuring no influences on bearing strength; and the back half section used for bearing less loads is of a welded structure, which is simple in shape, low in production cost and beneficial to being produced by batch. The front half section and the back half section are connected into a whole by the connecting bolts and are detachable, thus being convenient to the follow-up transportations extremely. The nacelle chassis of the wind generating set has the advantages of being reasonable in design, simple in structure, low in production cost, high in bearing strength, uniform in stress distribution and strong in practical applicability and being convenient to be produced by batch and transport and the like.
Description
Technical field
The utility model relates to wind power generating set, specifically is a kind of wind generating set engine room chassis.
Background technique
The chassis, cabin is the important composition parts of wind power generating set; It is not only bearing the various load from large parts such as wind wheel, spindle bearing holder, gear-box, generator, electric control cubicle, but also is bearing the influence of surrounding atmosphere to its pneumatic thrust and resistance.Therefore, cabin chassis structure designed rationality directly has influence on the smooth running of whole wind power generating set.
At present, common wind generating set engine room chassis structure is divided into two kinds, and a kind of is pure cast member, and another kind is pure weldment.Wherein, though pure cast member has the high advantage of bearing strength, it exists, and manufacture cost is high, complex forming technology, from heavy, defective such as inconvenience transportation etc.; Advantages such as moulding is simple though pure weldment has, low cost of manufacture, it exists, and bearing strength is low, fine finishing trouble, shaping efficiency are low, be unfavorable for defective such as batch process.
Summary of the invention
The purpose of the utility model is: to the deficiency of above-mentioned existing technology, under the prerequisite that guarantees bearing strength, provide that a kind of moulding is simple, low cost of manufacture, be beneficial to batchs process, from heavy and light, convenient wind generating set engine room chassis of transporting.
The technological scheme that the utility model adopts is: a kind of wind generating set engine room chassis, chassis, said cabin are divided into preceding half section and second half section, and preceding half section be cast member, and the second half section is a weldment, and preceding half section and second half section connect into integral body through many connecting bolts.
Be set with anti-loosening sleeve on the said connecting bolt.
Said preceding half section end face by preceding to after be provided with spindle bearing holder attachment face, gear-box supporting surface; Said preceding half section bottom surface is provided with tower tube adpting flange; Said preceding half section both sides are respectively equipped with driftage and drive adpting flange.
The said second half section mainly is welded by cover plate, base plate and both sides side plate.
Be welded with at least one horizontal stiffening rib on the said second half section.
Be welded with at least one waling on the said second half section.
The cover plate of said second half section is provided with generator backing plate is installed.
The beneficial effect of the utility model is: chassis, above-mentioned cabin is the composite structure of preceding casting, back weldering, for the preceding half section employing integral casting forming that bears main load, guarantees that bearing strength is unaffected; Second half section for bearing load is less is adopted welding structural body; Simple, the low cost of manufacture of moulding also is beneficial to batch process, and preceding half section connects into integral body with the second half section through connecting bolt; The two is detachable, greatly facilitates the subsequent transportation operation.The utlity model has that reasonable in design, simple in structure, low cost of manufacture, bearing strength are high, stress distribution evenly, be convenient to produce in batches, from characteristics such as heavy and light, convenient transportations.
