Description
Technical field
The utility model relates to a kind of pre-embedded bolt structures of adjustment type wind electricity blade blade root.
Background technique
Wind power generation blade needs to be bolted on host by blade root, and connection method mainly has T-bolt and pre-buried
Two kinds of technologies of bolt.At wind-powered electricity generation industry initial stage, fan power is smaller, and blade root load is small, using T-bolt mode simple process,
Quality is easy to control.With the development of the times, the drawbacks of length of blade and power are gradually increased, this connection type also shows
Come, such as because blade root pitch of bolts is larger, lead to blade root bolt limited amount, the load that blade root can be born is lower, blade root excision with
Punching generates more solid waste etc..And pre-embedded bolt connection type can be distributed under identical pitch diameter it is more polyaxial
Bolt, thus more big load can be born.Cancelling post-processing drilling link reduces the generation of waste material.But existing pre-buried spiral shell
Bolt is typically all to be perfused to be fixed in blade root, and the number of pre-embedded bolt and the position of installation are not adjustable after shaping,
Matched connection wheel hub will be so produced, the screw hole slightly deviation sometimes connected on wheel hub is just scrapped, if on blade root
Pre-embedded bolt can adjusting position according to the actual situation, then greater flexibility will be brought to installation and production.
