SUMMERY OF THE UTILITY MODEL
The utility model discloses an aim at be exactly to the not enough of above-mentioned prior art existence, provide a simple structure, convenient operation can realize the device of dismantling fan wheel that the high efficiency low risk not damaged of impeller demolishd.
In order to achieve the above purpose, the present invention adopts the following technical solution.
The utility model provides a device of dismantlement fan wheel, its characterized in that structure of device includes:
the positioning flange is a circular flat flange, and the circular ring of the flat flange is provided with bolt holes which are uniformly distributed and symmetrically distributed and have internal threads and threaded holes which are correspondingly matched with the threaded holes on the end surface of the fan impeller;
the force application flange is a flat flange plate, and threaded holes corresponding to the bolt holes in the positioning flange are formed in the flange;
the pull rod bolt is provided with external threads at two ends and is respectively matched and connected with the bolt hole on the positioning flange and the threaded hole on the force application flange; the end part of the pull rod bolt penetrating through the force application flange is provided with a fastening nut.
The utility model has the advantages that: the utility model discloses a device of fan wheel dismantles, simple structure, convenient operation can realize that fan wheel's high efficiency low risk not damaged demolishs, can effectively save the cost of labor.
