3D inspection of wind power tower flange

The wind power tower flange is a key support component of wind power equipment. It directly determines the service life of the wind turbine. However, it is the flange that plays a supporting and fixing role that affects the wind power tower. A large domestic wind power group invited HOLON3D to conduct research on the group. Wind power tower flanges undergo 3D measurement analysis to enable product improvements.

Facing problems

1. The wind power tower flange is a finished forging. It is used to quickly measure the flatness, inclination and ovality of the produced wind power tower flange for deformation measurement and analysis.

2. The diameter of the wind power tower flange is more than 2 meters and the height is about 1.5 meters. The customer requires fast measurement speed and high accuracy to complete this work.

Solution

The wind power tower flange is a finished forging, which has been normalized and tempered when it leaves the factory. Therefore, how to control this indicator and avoid controlling flatness, inclination and ovality through flame shaping is very practical. . The flange under the wind turbine is composed of three to four straight or conical cylinders, and the flanges at both ends are connected together through high-strength bolts to form a tower. Therefore, the flatness, angular deformation and ovality of the flange will directly affect the operation of the fan and affect the service life of the fan equipment.

1. Preparatory work

Attach landmark points: The acquired data can be positioned and spliced in the scanning software.

Paste coding points: enable the three-dimensional photogrammetry system to obtain the 3D coordinate values of the object surface.

More than 2m in diameter and about 1.5m high wind power tower flange

2. Three-dimensional photogrammetry

HOLON3D engineers used a three-dimensional photogrammetry system to obtain the 3D coordinates of the wind power tower flange surface in 10 minutes. They used a 3D photogrammetry system (HL-3DP) to take multiple images of the wind power tower flange. Through three-dimensional distance measurement, HOLON- The 3DP software automatically combines these images and performs calculations to obtain the 3D coordinates of the center of each coding point and calculate the 3D coordinates of key information points on the object surface.
