Wind power generator set base turning device and yaw system assembling platform and method

Abstract

The invention discloses a wind power generator set base turning device and a yaw system assembling platform and method. The wind power generator set base turning device comprises a turning assembly and a beam frame main body for supporting the turning assembly. The turning assembly comprises a slewing bearing. The slewing bearing comprises a fixed ring and a rotating ring which are connected together and can rotate relatively. The fixed ring is fixedly connected to the beam frame main body, and the rotating ring can rotate around a rotating shaft. One side of a mounting plate is bonded to therotating ring, and the other side of the mounting plate is the mounting surface on which a wind turbine generator set is mounted of the base. According to the wind power generator set base turning device, the base turning can be stably and safely realized, and the 360-degree turning can be realized, so that relevant accessories of the base are facilitated, and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to the field of assembly of wind power generating sets, in particular to a turning device for a base of a wind generating set, an assembly platform for a yaw system of a base of a wind generating set, and an assembly method. Background technique [0002] In recent years, the wind power industry has developed rapidly, especially with the rise of offshore wind power projects, the trend of high-power and large-scale development of wind turbines has become more and more obvious. With the enlargement of the wind power generating set, the volume and weight of each component of the wind generating set also increase accordingly. [0003] For direct-drive wind turbines, the base is an important load-bearing part in the yaw system of the wind turbine, connecting the yaw bearing and the fixed shaft of the generator, and supporting the related accessories of the yaw drive of the wind turbine. As the weight and volume of the base increases, t...

AI Technical Summary

Problems solved by technology

However, the existing base yaw system assembly method still uses manual assembly, which is labor-intensive, low operating efficiency, and assembly quality cannot be guaranteed

[0004] In addition, in the existing assembly method, the manual operation of the crane and the spreader is usually used to lift and turn the base of the wind turbine, which can only be turned 90 degrees at a time, and there are problems such as difficult operation and low production efficiency

In addition, in the process of hoisting and overturning by driving, a slight inappropriateness will cause damage to the parts, and there are often potential safety hazards due to the difficulty in meeting the requirements for the strength of the sling / sling

[0005] Therefore, the existing base yaw system assembly method can no longer meet the efficiency, quality and safety requirements of large-scale wind turbine assembly
