Detailed Description
The present invention will be further described with reference to the following embodiments.
A huge nut screwing device of a water turbine comprises a rotor 1, a shaft sleeve 2, a connecting frame 3 and a motor 4;
the inner part of the rotor 1 is provided with an inner hexagonal tubular structure matched with the giant nut, and the inner part of the rotor 1 is communicated up and down; the outer surface of the rotor 1 is sequentially provided with an outer gear ring 11, a positioning shaft shoulder 12 and a shaft diameter;
the shaft sleeve 2 is rotationally connected to the shaft diameter of the rotor 1;
the connecting frame 3 is fixed with the shaft sleeve 2;
the motor 4 is fixed on the connecting frame 3, a gear 5 is installed on an output shaft of the motor 4, and the gear 5 is meshed with an outer gear ring 11 of the rotor 1. An output shaft of the motor 4 rotates to drive the gear 5 to rotate, and the gear 5 is in transmission with the outer gear ring 11 to further drive the rotor 1 to rotate in the shaft sleeve 2; because the interior of the rotor 1 is communicated up and down, the technical problem that the stud cannot be screwed in continuously when the stud exceeds the nut for a long time is solved, and in addition, the motor 4 and the rotor do not belong to the same rotation center, so the technical problem that the inner hexagonal sleeve cannot work normally when the spindle of the water turbine blocks the motor is solved.
The outer surface of the rotor 1 is detachably connected with a positioning ring 6, and the positioning ring 6 is positioned below the shaft sleeve 2. Simple structure and convenient installation.
