Abstract

The invention discloses an ovality adjusting tool for a flange of a wind power tower drum and a manufacturing and application method of the ovality adjusting tool. The tool comprises a correction plate and a hollow correction supporting pipe, wherein the hollow correction supporting pipe and the correction plate are of a T-shaped structure, the correction plate is clamped to one end of the hollow correction supporting pipe, and an arc-shaped gasket is arranged on the side wall of the other end of the hollow correction supporting pipe. According to the tool, the correction plate, the hollow correction supporting pipe and the arc-shaped gasket are arranged in a combined mode to be used in cooperation with a hydraulic jack to adjust the ovality of the flange of the wind power tower drum, adjustment is accurate, connection dislocation of a foundation drum section is avoided, the tool is simplified, the adjustment efficiency is improved, and the labor cost and the machining cost are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a tool for adjusting the ellipticity of a flange of a wind power tower and its manufacturing and application methods. Background technique [0002] A wind power tower is generally composed of a number of foundation tubes connected by flanges. The deviation of the ellipticity of the flanges affects the service life of the wind power tower and is critical to the safe operation of subsequent wind turbines. However, in fact, due to the influence of self-weight and other factors, the ovality of the flange will inevitably deviate; for this reason, it is often necessary to adjust the ovality of the flange of the wind power tower. [0003] At present, the ellipticity of the flange reaches the qualified standard by means of multi-stage mechanic assembling jacks, but this kind of mechanical tooling has many parts, complicated operation, low adjustment efficiency and adjustmen...
