Description
Technical field
The present invention relates to the servicing unit of the laying glass cloth in a kind of manufacture process of large-scale composite material blade, particularly a kind of laying method and servicing unit thereof of laying wind electricity blade root glass cloth.
Background technology
In wind power equipment, the blade of wind-driven generator is important critical component, and its performance has directly influenced the generated output of generating set.And the main material of making blade is glass cloth and perfusion resin, the use amount of glass cloth is very big in the MW class blade, leaf root part glass cloth at blade can reach 100 multilayers, and so multilayer glass cloth will lean on operating personnel to lay above blade mold layer by layer, need take a long time, be unfavorable for large-scale production, so, artificial first shortcoming of directly laying glass cloth is: it is oversize to take the mould time, be unfavorable for improving blade production efficiency, can not satisfy the demand that big specification is produced.
Artificial second shortcoming of directly laying glass cloth: the glass cloth stored collapsed of pre-cut easily forms folding line, causes bulge, fold phenomenon when laying easily, reduces the intensity of blade and the performance of itself.
Artificial the 3rd shortcoming of directly laying glass cloth: because the leaf root part circular arc of MW class blade mold is bigger, when glass cloth is laid, the two ends of glass cloth are easy to glide, cause the in uneven thickness of root glass cloth, the inequality of blade root thickness will and be carried out operation such as bolt installation to the punching of follow-up blade and be affected.
Summary of the invention
The present invention has mainly solved the deficiency of existing shop layer technology, provides that a kind of cost of manufacture is low, technological operation convenient, laying speed is fast, in the time of adapting to the large-scale production wind electricity blade, lays the laying method and the servicing unit of wind electricity blade root glass cloth.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of laying method of laying wind electricity blade root glass cloth, earlier a fixed support is fixed, on being installed in semicircle steel plate profile on the fixed support again, and glass cloth holddown groove is installed in semicircle steel plate profile two ends, launch fully waiting to lay glass cloth again, cover on semicircle steel plate profile, and the two ends that guarantee the two-layer glass cloth of first and last at least exceed outside the glass cloth holddown groove, make glass cloth can push down glass cloth when fixedly square steel is pressed on the glass cloth holddown groove, then with glass cloth fixedly square steel be pressed on the glass cloth on the glass cloth holddown groove, when every laying finishes 5～10 layers of glass cloth, utilization is set fabrication hole on circular steel template face, by the fixing glass cloth of colligation, makes glass cloth be fixed as an integral body, and reach straight, the effect of alignment; After blade root glass cloth has been laid, with C type anchor clamps, the fixedly square steel of glass cloth and glass cloth bottom is clamped, to prevent that glass cloth from sliding, distortion.After blade root glass cloth has been spread, connect with lifting rope and device profile, and be connected with the driving hook, the cloth spreading device profile is sling directly put into blade mold.Lay down C type anchor clamps, hang away the cloth spreading device profile again, root glass cloth is laid and is finished.The bottom fixed support of device still can be used for the laying of next cover glass.
Servicing unit according to the laying wind electricity blade root glass cloth that said method proposed, comprise semicircle steel plate profile, glass cloth holddown groove, fixed support, on semicircle steel plate profile was installed on the fixed support, semicircle steel plate profile two ends were glass cloth holddown groove, and glass cloth holddown groove is provided with fixedly square steel, semicircle steel plate profile is provided with fabrication hole, and fabrication hole is circular or square.
It uses step to be: earlier cloth spreading device is located, on device, lay glass cloth according to blade root shop layer order then, the certain number of plies glass of every laying cloth is fixed it, after glass cloth has all been spread, the device of directly slinging, be put in the middle of the housing, the bottom steelframe of device still can be used for the laying of next cover glass.This device uses simple, and technological operation is convenient, glass cloth laying quality is good, and the lifting time is fast; Make simply, easy to assembly, cost is low, long service life.
