Abstract

The invention provides a bolt fast installation device and an assembly method for a wind driven generator hub. The bolt fast installation device comprises a fixing part and baffles, wherein the fixing part is provided with two or more rotation preventing structures which are arranged at intervals and are used for clamping a screw cap of a bolt or a nut matched with the bolt in the radial direction; and the baffles are installed on the fixing part and are arranged on the outer sides of the corresponding rotation preventing structures, the distance between the baffles and the rotation preventing structures is smaller than the height of the screw cap or the nut, or the baffles are directly attached to the parts of the rotation preventing structures of the fixing part to be used for axially supporting the screw cap or the nut. The bolt fast installation device is simple in structure, convenient to operate and capable of fast fixing the bolt, so that the bolt is kept fixed in the nut installation process and cannot turn around; and therefore manual operation during bolt installation is facilitated, the work efficiency is improved, and the labor cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of mechanical tools, and in particular relates to a fast bolt installation device and an assembly method for a hub of a wind power generator. Background technique

[0002] At present, for ordinary bolted connections, in order to prevent the bolts from rotating together when the nuts are tightened, it is generally necessary to fix the nuts of the bolts with a wrench, which not only requires manual operation, but also operates the fixed nut when tightening the nuts One end of the wrench also needs to be continuously applied by the person to fix the force of the wrench to prevent the nut from loosening from the wrench.

[0003] The usual solution is to set an anti-rotation structure in the bolt hole where the bolt is installed:

[0004] For example, a groove that cooperates with the nut to prevent rotation is designed at the end of the bolt hole close to the nut. When the nut is embedded in the groove, the gro...
