Embodiment 1

[0014] Example 1, such as figure 1 As shown, a wind power generation base ring elliptical hole cutting process is characterized in that: the basic ring 1 is an annular steel cylinder, and the elliptical hole 2 is arranged on the annular steel cylinder. The process includes the following steps:

[0015] Step 1), selection of steel: according to the weight of the fan tower, the weight of the base ring 1, the diameter of the base ring 1, the thickness of the tube wall, the number of elliptical holes 2, and the size of the elliptical hole 2, select steel types of different strength levels, to meet the strength requirements;

[0016] Step 2), cutting machine data programming: according to the number and size of the oval hole 2, data programming is performed on the CNC plasma cutting machine;

[0017] Step 3) Cutting rehearsal: According to the programmed data, perform cutting rehearsal on the base ring 1. The cutting rehearsal includes large ellipse arc cutting rehearsal a...

Abstract

The invention relates to a wind power generation foundation ring elliptical hole cutting process. A foundation ring serves as an annular steel cylinder body, and elliptical holes are formed in the annular steel cylinder body. Firstly, types of steel at different strength levels is selected so that the requirement for the strength of the foundation ring can be met, data programming is conducted on a numerical control plasma cutting machine according to the number of the elliptical holes and the sizes of the elliptical holes, then, the cutting rehearsal is conducted on the foundation ring, whether cutting route positioning is appropriate or not is detected, the positions of the foundation ring and a cutting guide rail are adjusted so that the distance between the foundation ring and the guide rail can be within 6mm, large elliptical arc cutting and small elliptical arc cutting are conducted on the foundation ring according to data programming of cutting machine rehearsal, and grinding is conducted after cutting. By means of the wind power generation foundation ring elliptical hole cutting process, the elliptical holes of the foundation ring are easier and more convenient to cut, no notches can not be reserved in the cut elliptical holes, the integrality of the elliptical holes is higher, the foundation ring is firmer and more durable in use, the construction safety of the foundation ring is ensured, the implementation scheduling of a wind power generation tower barrel is ensured, and production cost of a wind power generation tower is reduced.

Description

technical field [0001] The invention belongs to the technical field of wind power generation base rings, in particular to an elliptical hole cutting process for wind power generation base rings. Background technique [0002] There is an elliptical hole between the upper and lower flanges of the foundation ring of wind power generation. The force transmission between the foundation ring and the foundation concrete is realized through the ellipse hole and the flange. At the same time, the steel bar passes through the ellipse hole to the concrete inside the foundation ring. Increased integrity of the inner and outer structures of the base ring. At present, the elliptical hole on the foundation ring often leaves a gap when it is cut. Excessive pressure will cause the gap to crack, causing the ellipse hole of the foundation ring to deform, which brings safety hazards to the construction of the foundation ring and seriously affects the wind power tower. construction progress. C...
