Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. bed hedgehopping seat, 2. stiffening rib, 3. girder, 4. lifting is with the circle cover, and 5. the adpting flange plate 6. prolongs beam, 7. tail end balance weight body, 8. fine setting balancing weight.
Embodiment
As shown in Figure 1, a kind of process blade of the present utility model is connected on the pitch variable bearings, comprises at least: a girder 3, a bed hedgehopping seat 1, prolong a beam 6 and a tail end balance weight body 7.Girder 3 is a long column shape, is connected stiffening rib 2 between girder 3 ends and girder 3 main bodys, and stiffening rib 2 is outer to be with the circular cone strengthening sleeve, effectively increases girder 3 intensity, reduces the blade amount of deflection, prevents girder 3 distortion.Girder 3 is the main body of process blade, has enough resistance to flexures.Bed hedgehopping seat 1 one ends are connected with pitch variable bearings by bolt, the other end is connected with girder 3 end flange bolts, and the two sides of bed hedgehopping seat 1 is all joined and bore to be installed with bolt hole and adopt hollow-core construction, effectively dodges the pitch variable bearings accessory, as connecting transition piece, be convenient to assembling simultaneously.Prolonging beam 6 is long column shape, is connected girder 3 tail ends, and the adpting flange plate 5 by two ends is connected with tail end balance weight body 7 with girder 3.Is furnished with and the different quality of adpting flange plate 5 same specifications and the prolongation beam 6 of length the convenient process blade of realizing the multiple specification of quality by loading.Tail end balance weight body 7 is connected girder 3 tail ends by adpting flange plate 5, tail end balance weight body 7 preferably adopts identical in quality some, evenly be connected girder 3 tail ends respectively, gravity that can the balance tail end, it can play in the blade finite length, move after making blade center of gravity, and increase blade rotation inertia value in proportion according to the quality multiple.At least one fine setting balancing weight 8 is connected girder 3 or prolongs beam 6 or tail end balance weight body 7 tail ends, in the blade finite length, and the position of centre of gravity and the rotary inertia of fine setting blade, and can regulate the rotary inertia that increases because of the blade amount of deflection.Flanged plate 5 connects girder 3 and tail balancing weight part, and lifting increases girder 3 intensity with the circle cover 4 outer girders 3 that are wrapped in, and makes things convenient for handling and assembling.
During assembling, at first becoming installation bed hedgehopping seat 1 on the slurry bearing, handling girder 3 and 1 assembling of bed hedgehopping seat again after the bolton, test is as needing the process blade of the another kind of specification of quality, then, only need to realize, need not removal bed hedgehopping seat with addition of the prolongation beam 6 of corresponding specification by adpting flange plate 5, easy to assembly, safe and reliable.
