Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling, in particular to a simple assembly auxiliary tooling for a steel-concrete tower of a wind turbine generator set. Background Art

[0002] With the further development and utilization of wind resources in my country, wind turbines are gradually developing towards high power and high altitude. Traditional wind power flexible all-steel tower technology can no longer meet the demand for high rigidity and large diameter wind turbine towers. In recent years, with the promotion of prefabricated concrete technology in my country, the application of prefabricated concrete towers in the field of wind power generation has become increasingly common, effectively making up for the low rigidity and small diameter shortcomings of flexible steel towers. Generally speaking, after the mixed tower components are transported to the wind farm site, they must first be pre-assembled on a pre-assembly platform (the first section of the mixed tower is on the foundation of the wind turbine) to form a whole segment before the entire section is hoisted. Among them, the rounded corner components must be positioned on the foundation or pre-assembly platform before assembly, and the positioning lines must be drawn to achieve the purpose of accurate installation of the rounded corner components.

[0003] Chinese patent publication number CN217518784U discloses a simplified auxiliary tool for assembling steel-concrete towers for wind turbine generator systems. This auxiliary tool is mounted on a foundation and comprises two curved arms connected at one end by a connector. Opposite sides of the connector are hingedly connected to the two arms. This auxiliary tool is placed on a foundation or pre-assembly platform to facilitate the precise installation of rounded corner components, replacing the traditional method of manually measuring and drawing positioning lines with a tape measure.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: when in use, the above-mentioned solution is connected to the existing structure through the support arm. Since the curvature of the support arm is fixed during use, it is not convenient to adjust, which reduces the compatibility of the above-mentioned device with different wind turbines in actual use.
