Description

Technical Field

[0001] The present invention relates to the technical field of wind power tower installation, and in particular to auxiliary equipment for wind power tower installation and an installation method thereof. Background Art

[0002] The wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the set. The production process of the wind turbine tower is generally as follows: CNC cutting machine unloads, thick plates need to be beveled, and the plate rolling machine rolls the plate into shape, spot welding, positioning, and confirmation before welding the inner and outer longitudinal seams. After the roundness inspection, if there is a problem, a secondary rounding is performed. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, non-destructive testing and flatness inspection of the weld are performed, sandblasting, painting, internal parts installation and finished product inspection are completed, and then it is transported to the installation site.

[0003] At present, when installing wind turbine towers, auxiliary equipment is usually needed to assist in the installation, so as to align the towers in the upper and lower positions to prevent misalignment that leads to installation failure, or even damage or breakage of the towers. Existing auxiliary equipment usually uses pressure sensors for detection. When the tower contacts the sensor, an electrical signal will be released to facilitate observation by operators. Due to the heavy weight of the tower itself and the high position during installation, it needs to be hoisted and installed with the help of lifting devices such as tower cranes. Although detection devices such as pressure sensors can detect the position of the tower;

[0004] However, in actual use, since wind turbine towers are usually installed in areas with rich wind resources, they are easily affected by wind and cause the tower to shake when they are hoisted and aligned. As a result, the tower may still be affected by wind and deviate from the preset position during the downward movement after detection, resulting in collision and damage between the upper and lower towers. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that the tower is easily affected by wind and causes shaking, and may still be affected by wind to deviate from the preset position during the downward movement after detection, thereby causing collision and damage between the upper and lower towers.
