Production system for manufacturing crossbeam or auxiliary beam of wind blade by adopting pull-extrusion molded plate

Abstract

The invention discloses a production system for manufacturing a crossbeam or an auxiliary beam of a wind blade by adopting pull-extrusion molded plates. The production system comprises a stacking platform, bundling mechanisms and a lifting mechanism; a plurality of bundling mechanisms are arranged along the length direction of the stacking platform; the lifting mechanism comprises a crane, a lifting tool, a plurality of lifting appliances and telescopic rods; the telescopic rods are connected with the lifting tool and the lifting appliances, are rigid telescopic rods and correspond to the lifting appliances one by one in amount; and the plurality of lifting appliances are arranged in pairs along the length direction of the stacking platform. According to the production system disclosed by the invention, the stacking platform is used for assembling of the pull-extrusion molded plates; the assembled pull-extrusion molded plates are bundled to form a prefabricated beam; subsequently the prefabricated beam is conveyed to a specified position of a blade shell by using the lifting mechanism; by the rigid telescopic rods of the lifting mechanism, the prefabricated crossbeam or auxiliary beam of the wind blade and a fabricated plate layer are kept in an arc surface shape along the length direction and the width direction during a lifting process, are also free from deformation and need not to be adjusted again after being placed at the position of the shell; and the production system is low in cost and scientific and reasonable in design.

Description

Technical field [0001] The invention relates to a production system for manufacturing wind turbine blade beams or auxiliary beams by using pultruded plates. Background technique [0002] With the continuous growth of fan blades, the longest blade has reached more than 60 meters, and some manufacturers are even preparing to make blades of 75 meters. The original vacuum-infused FRP blades have failed to meet the requirements of large-scale and lightweight blades in terms of strength and rigidity. In order to be able to adapt to the current development needs of wind power generation, many manufacturers have improved the existing blade production process and technology, so as to enable the wind turbine blade to have higher strength and modulus, while being able to make it lighter and lighter. The use of carbon fiber to make wind turbine blades and their various components is currently a mainstream direction. Wind power companies such as VESTA S, TPI, Jinfeng Technology, Zhongfu Lian...

Problems solved by technology

But in this method, one mold can only be adapted to one type, and the cost is very high, and the injection is performed in stages (one injection in the production of the girder or auxiliary beam, and one injection after forming the blade), and the combination of the girder or auxiliary beam and the shell There will be certain problems between them, and the performance is not good enough
