Description
Technical field
The present invention relates to a kind of pre-embedded bolt structures of wind electricity blade blade root.
Background technology
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, simple for process using T-bolt mode,
Quality is easy to control.With the development of the times, the drawbacks of length of blade and power gradually increase, this connection type also shows
Come, such as because blade root pitch of bolts is larger, cause blade root bolt quantity limited, the load that blade root can be born is relatively low, 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 cannot all be adjusted after shaping,
Mating 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 be according to actual conditions adjusting position, then installation and production will be given to bring greater flexibility.

The encapsulation ring body stated is socketed in the outside of blade root；The inside arc clamping annular groove and outer arcuate clamping ring groove position corresponds to
And constitute pre-embedded bolt buckling groove.
Further, the blade root lower outside is equipped with multiple locking screw thread holes；The lower part of the encapsulation ring body is equipped with
Multiple locking jack holes；The locking jack hole and locking screw thread hole site correspond to；The lock screw from encapsulation ring body
Outside pass through locking jack hole rear thread be connected in locking screw thread hole.
Further, the encapsulation ring body and lock screw are made of titanium alloy material.
Further, the pre-embedded bolt buckling groove and card teeth are in inverted T-shaped structure.
Further, the encapsulation ring body is docked by two semicircular buttcover plates.
Beneficial effects of the present invention
The pre-embedded bolt mounting structure design of the present invention is ingenious, and pre-embedded bolt is mounted on blade root and encapsulates the pre-buried spiral shell that ring body is constituted
In bolt buckling groove, and multiple pre-embedded bolts are connected to by card teeth sliding in pre-embedded bolt buckling groove, and pre-embedded bolt
Nonrigid connector is installed between the card teeth of bottom so that pre-embedded bolt is installed more steady, so can be according to practical need
It seeks the pre-embedded bolt for choosing suitable number, and during installation slides pre-embedded bolt to adjust rational installation site,
Using more flexibly.
