Problems solved by technology
Due to the need to manually detect the position of the mounting hole of the corbel multiple times, there is a certain error in each detection, and it is not convenient to use positioning and measurement when detecting the mounting hole. After installing multiple corbels, it is very easy to cause mounting holes on the corbel. There is a large misalignment with the mounting holes on the generator assembly, so the position of the corbel needs to be adjusted repeatedly, which is very troublesome to install

Embodiment Construction
[0019] The corbel 2 includes a vertical connecting portion 21 and a horizontal connecting block 22, and the connecting block 22 is provided with a mounting hole 220 penetrating in the longitudinal direction. The installation method of the corbel 2 in the lower cover of the wind turbine nacelle includes the following steps:
[0020] a. Suspend gravity hammer group 1, determine the number of gravity hammer groups 1 according to the number of corbels 2 that need to be installed as a whole, so that the gravity hammer on gravity hammer group 1 can correspond to the corbels that need to be installed one by one, according to Adjust the spatial position of each weight on the gravity hammer group 1 by pre-setting the positions of the mounting holes on each bracket;
[0021] b. Place the opening of the lower cover of the nacelle facing upwards, hang the gravity hammer group 1 above the lower cover of the nacelle, select a gravity hammer, and translate the gravity as a whole according to...

The invention discloses an installation method of corbels inside a lower cover of a machinery space of a wind motor, comprising the following steps: a suspending a gravity hammer set, and positioningthe space position of each gravity hammer of the gravity hammer set according to preset positions among installation holes positioned on the corbels; b arranging the opening of the lower cover upwards, suspending the gravity hammer set above the lower cover of the machinery space, and integrally translating the gravity hammer set according to the preset installation positions of the corbels in thelower cover of the machinery space; c installing the corbels one by one, i.e. clamping the corbels, moving the corbels into the lower cover of the machinery space, regulating the corbels so that thecenters of the installation holes positioned on the corbels are coincided with the tip ends of the gravity hammers of the gravity hammer set, which are positioned at the installation positions, and then fixedly connecting the corbels with the inner wall of the lower cover of the machinery space. The invention aims at providing the installation method of the corbels inside the lower cover of the machinery space, which integrally positions the installation positions of the corbels by one time and then installs the corbels so as to realize the accurate positioning of the installation holes of thecorbels.
Description
[technical field] [0001] The invention relates to a method for installing a corbel inside a lower cover of a wind turbine nacelle. [Background technique] [0002] The existing wind turbine nacelle cover is generally formed by connecting an upper cover and a lower cover, and the generator assembly for generating electricity is installed in the lower cover of the nacelle. Since the generator assembly of a large wind turbine is relatively large, in order to make the connection of the generator assembly firm, the generator assembly and the inner wall of the lower cover of the nacelle are often connected by a corbel. During installation, the corbels are fixedly connected to the inner wall of the lower cover of the nacelle, and then the generator assembly is sent into the lower cover for installation. Mounting holes connected to the motor are respectively provided on each corbel and locked with bolts and nuts, which can enhance the firmness of the whole. [0003] In the prior ar...
