Layer paving device and layer paving method for main girder glass fiber cloth used for wind power blade production

Abstract

The invention discloses a layer paving device for main girder glass fiber cloth used for wind power blade production. The layer paving device comprises a frame body and a supporting structure, wherein wheels are arranged at the bottom of the frame body, the supporting structure consists of four sets of fixing frames, each set of fixing frame comprises an upper fixing frame and a lower fixing frame, two sides of the lower fixing frame extend outwards to form right-angled folding ears, G-shaped clamping devices are arranged at parts corresponding to the right-angled folding ears on two sides of the upper fixing frame; the invention also discloses a layer paving method of the layer paving device for main girder glass fiber cloth used for wind power blade production, by placing the layer paving device on a guide rail and moving the layer paving device to one end of a mould, a glass fiber cloth roll is placed, and then glass fiber cloth is pulled out and fixed at one end of the mould, the layer paving device for main girder glass fiber cloth is pushed to the other end of the mould, and the operation is repeated until all layer paving is completed; and the layer paving device and the layer paving method which are disclosed by the invention can pave glass fiber cloth into the mould rapidly, accurately and smoothly, so that the subsequent manual adjustment is reduced, the time and manpower for adjustment of glass fiber cloth after laying are saved, and the laying efficiency is improved while guaranteeing the laying quality.

Description

technical field [0001] The invention relates to a main girder glass fiber cloth laying device and laying method used for the manufacture of wind power blades when the main girder of the wind energy blade is cast, and belongs to the technical field of wind energy blade manufacturing. Background technique [0002] FRP wind energy blade is a key component of wind power equipment, and its manufacturing cost accounts for about 15%-20% of the total cost of the fan; there is a prefabricated part in the FRP wind energy blade called the main beam, which is a load-bearing structure. During the manufacturing process, it needs to be placed in the mold Laying dozens of layers of glass fiber cloth, in the prior art, generally: It takes a long time for operators to lay layers on the blade mold layer by layer, which is not conducive to large-scale production; The roll of glass fiber cloth is hoisted by the crane and moved to the top of the mold for laying. However, this method is slow an...

[0002] FRP wind energy blade is a key component of wind power equipment, and its manufacturing cost accounts for about 15%-20% of the total cost of the fan; there is a prefabricated part in the FRP wind energy blade called the main beam, which is a load-bearing structure. During the manufacturing process, it needs to be placed in the mold Laying dozens of layers of glass fiber cloth, in the prior art, generally: It takes a long time for operators to lay layers on the blade mold layer by layer, which is not conducive to large-scale production; Use the crane to hang the glass fiber cloth roll, move it to the top of the mold for laying, but this method is slow and inefficient, and it is difficult to accurately lay the glass fiber cloth into the mold, and it is difficult to lay the cloth flat

[0003] In the existing actual production, after laying the glass fiber cloth, it takes a lot of manpower to adjust and level the laid glass fiber cloth, which is not only time-consuming and laborious, but also seriously affects the post-forming The quality of the product, how to provide a main beam glass fiber cloth laying device and its laying method that can overcome the above defects has become a technical problem to be solved urgently by those skilled in the art
