Description

Chamfering method of post-treatment production line of pultruded plates for wind power blade girder

Technical Field

The invention relates to a chamfering method of a post-treatment production line of a pultruded plate for a wind power blade girder.

Background

Along with the increasing approaching of traditional fossil energy consumption schedules such as coal, petroleum, natural gas and the like, the development and the utilization of wind energy are more and more paid attention to, and the wind energy has become one of the most commercial popularization prospect projects in the energy field, and is rapidly developed at home and abroad at present. Wind power generation is mainly realized through a wind power generator, wind power blades are core components of the wind power generator, and wind power pushes the wind power blades to rotate so as to drive the generator to generate current.

Wind power blades are usually formed by an outer contour of an upper shell and a lower shell, the inside of the wind power blade is borne by using a girder-web structure, and the girder is a main framework structure in a blade component, and the quality of the girder directly influences the quality of the wind power blade. Blade girders are typically injection molded using blade molds. Before the blade is poured and molded, multiple layers of cloth with equal width are paved on the inner surface of the blade mold so as to meet the rigidity requirement of the molded blade and ensure the mechanical property of the blade. In the prior art, cloth on the inner surface of the blade die is paved by lifting the cloth rolls to the die through a travelling crane, the cloth is paved through the free ends on two sides of the cloth rolls under manual control, after one roll is paved, workers need to return to the original point to lay and stack the other cloth roll again, time and labor are wasted, in the paving process, the center of the cloth layer needs to be manually adjusted to coincide with the center of the die, the labor intensity of manually rolling the cloth is high, the cloth rolls roll inflexibly, and the work efficiency is low. In addition, because the inner surface of the wind power blade mould is an irregular curved surface (the wind power blade girder comprises a windward girder and a leeward girder, the upper surface of the windward girder is an upward convex cambered surface, and the lower surface of the leeward girder is an upward concave cambered surface). Meanwhile, the length of the wind power blade mould is 50-80 m, the width of the mould can reach 3-4 m, operators need to enter the wind power blade mould to carry out layering in the production process, the common practice is to adopt pultrusion plates with the same thickness and width to carry out layering, and then the width and the end part of each section of each layer have irregular shapes in design due to the complexity of the actual structure of the wind power blade girder. Therefore, the optimal practice is not to lay the pultruded plates back and forth in the usual way, but to accurately cut and chamfer the width of the pultruded plates of each layer through accurate simulation calculation, and finally to lay the pultruded plates of each layer and to lay the plates in a staggered mode and then to pour the die.
