Wind power blade pultrusion plate shape follow-up tensioning device

Abstract

The invention relates to a wind power blade pultrusion plate shape follow-up tensioning device. The device comprises an upper cross beam and a lower cross beam which are arranged up and down, a tensioning lead screw penetrates through the middle of the upper cross beam and the middle of the lower cross beam, and guide columns penetrate through the left section and the right section of the upper cross beam and the left section and the right section of the lower cross beam respectively. The front side surface and the rear side surface of the lower cross beam are each provided with a shape follow-up plate, the bottom of each shape follow-up plate is provided with a downward arc curve, the width of each shape follow-up plate is larger than that of the lower cross beam, and the portions, extending out of the lower cross beam, of the front shape follow-up plate and the rear shape follow-up plate are connected with a front-back-through connecting pipe. Tensioning belt steering pipes are connected between the left ends and the right ends of the front shape follow-up plate and the rear shape follow-up plate. A tensioning belt tightener is arranged at the right end of the upper cross beam. The wind power blade pultrusion plate shape follow-up tensioning device has the advantages of being good in universality, low in cost and convenient to use.

Description

technical field [0001] The invention relates to a conformal tensioning device for pultruded plates of wind power blades. Background technique [0002] In order to transport the stacked fiberboards of wind turbine blades as a whole, the patent No. 2020214205756 discloses a tensioning device for tensioning the carbon fiberboards of wind blades, which is used to clamp the stacked fiberboards of wind turbine blades. However, this scheme has the following disadvantages: [0003] 1. This kind of structure is an integral form, and the radian of the bottom surface of the forming board is fixed, which cannot be adjusted according to the radian of the top surface of the fiberboard of the wind turbine blade, so the universal type is poor; [0004] 2. Since multiple tensioning devices are required at different positions for the overall transportation of the stacked wind turbine blade fiberboards, and the elevator with this structure is in the form of a whole, the overall cost is relati...

Problems solved by technology

[0003] 1. This kind of structure is an integral form, and the radian of the bottom surface of the forming board is fixed, which cannot be adjusted according to the radian of the top surface of the fiberboard of the wind turbine blade, so the universal type is poor;

[0004] 2. Since multiple tensioning devices are required at different positions for the overall transportation of the stacked wind turbine blade fiberboards, and the elevator with this structure is in an integral form, the overall cost is relatively high;

[0005] 3. The width of the forming board is fixed, and it can only be used for tensioning and fixing the fiberboard of wind turbine blades with the corresponding width, and the universal type is also poor.
