Description

Technical Field

[0001] This utility model belongs to the field of web plate support technology, and in particular relates to a C-shaped support tool for the web plate of a wind turbine blade. Background Technology

[0002] The web of a wind turbine blade is one of the main components, used to support the blade shell and bear the bending loads received by the blade. It is generally composed of two prefabricated C-shaped or I-shaped webs connected together. During the mold closing process, the C-shaped opening at the root of the web is prone to deformation (the web is flexible), which poses a risk of delamination and glue thickness issues during bonding.

[0003] Currently, the C-shaped deformation is controlled by either a simple support device or by adjusting the web mold. The simple support device is not adjustable, has poor compatibility, and is not suitable for different blade models, resulting in poor versatility. Adjusting the web mold requires a long time and manpower for each adjustment, and multiple trials are needed to achieve the desired state, leading to high costs and labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a C-shaped support fixture for the web of a wind turbine blade, which can adjust the height of a simple device, has high versatility, and can meet the needs of various types of blade webs.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a C-shaped opening support fixture for the web of a wind turbine blade, comprising an adjustment assembly and two sets of support assemblies, wherein the two sets of support assemblies are respectively disposed on both sides of the adjustment assembly, and the adjustment assembly is used to adjust the distance between the two sets of support assemblies; the support assembly includes a support rod and a support structure, the support structure including multiple sets of support blocks of different models; the support rod can be detachably connected to the adjustment assembly; the support blocks are used to support the C-shaped opening.

[0006] Furthermore, the adjustment assembly includes a hand-cranked top, a first connecting rod, and a second connecting rod. The two sides of the first connecting rod are respectively connected to the bottom of the hand-cranked top and the support rod of a set of support components; the two sides of the second connecting rod are respectively connected to the top end of the hand-cranked top and the support rod of another set of support components.

[0007] Furthermore, the support rod and the first connecting rod, and the support rod and the second connecting rod are detachably connected by a connecting structure.

[0008] Furthermore, the connecting structure includes nuts and bolts, and the first connecting rod, the second connecting rod, and the support rod are hollow rods; one set of nuts and bolts of the connecting structure are respectively fixed on the side of the first connecting rod and the support rod that are close to each other, and another set of nuts and bolts of the connecting structure are respectively fixed on the side of the second connecting rod and the support rod that are close to each other; the bolts can be threadedly connected to the nuts.

[0009] Furthermore, a protective pad is provided on the side of the support block away from the adjustment component.

[0010] Furthermore, the protective pad is made of EVA.

[0011] The working principle of this technical solution is as follows: Select a suitable support block and connect the support rod to the first connecting rod and the second connecting rod. Then rotate the hand-cranked jack, causing the lifting end of the hand-cranked jack to drive the second connecting rod to move vertically, thereby changing the height of the entire support fixture until the EVA pad is tightly closed to the C-shaped opening of the web plate.

[0012] The beneficial effects of this technical solution are as follows:

[0013] ① This tooling design is simple in structure, easy to operate, and improves efficiency.

[0014] ② By setting different types of support blocks, the entire support fixture has high versatility and can meet the needs of various types of blade webs.

[0015] ③ The deformation of the web plate can be controlled without adjusting the web plate mold, saving manufacturing costs and manpower.

[0016] ④ By setting protective pads, the surface of the web plate can be protected and scratches can be avoided. Attached Figure Description
