Problems solved by technology

In this process, the force direction and magnitude between the rotor back wheel and the sleeper board will change with the inclination angle of the rotor, and if the friction between the sleeper board and the ground is not large enough, it will cause the sleeper board to slide, thus affecting to the stability of the rotor and bump
The whole overturning process is extremely risky and time-consuming, and there are great potential safety hazards and equipment damage risks

Abstract

The invention relates to an overturning device for a main pump motor rotor of a nuclear power plant, comprising: a support frame; rotatably arranged on the support frame to connect with the main pump motor rotor of the nuclear power plant and drive the rotor of the main pump motor of the nuclear power plant to overturn through connection and fixation A frame; a rotating mechanism that rotatably connects the connecting frame and the supporting frame; it is arranged on the supporting frame to lock the connecting frame when the connecting frame rotates a first preset angle in a first direction a first locking mechanism; a second locking mechanism provided on the support frame to lock the connecting and fixing frame when the connecting and fixing frame rotates to a second preset angle in a second direction. The rotor turning device of the main pump motor of the nuclear power plant can facilitate the turning and positioning of the rotor of the main pump motor of the nuclear power plant, improve the working efficiency of the rotor turning, and reduce the safety hazards and equipment damage risks during installation.

Description

technical field [0001] The invention relates to the maintenance technology of the main pump motor, and more specifically relates to a rotor turning device for the main pump motor of a nuclear power plant. Background technique [0002] During the full inspection of the main pump motor, the motor rotor (about 9 tons in weight and about 4.2 meters in length) needs to be pulled out vertically, turned over 90 degrees, and then placed horizontally. On the sleeper board on the ground, then the driving hook moves horizontally while falling, and slowly puts down the rotor to turn over. In this process, the force direction and magnitude between the rotor back wheel and the sleeper board will change with the inclination angle of the rotor, and if the friction between the sleeper board and the ground is not large enough, it will cause the sleeper board to slide, thus affecting to the stability of the rotor and bumping occurs. The entire flipping process is extremely risky and time-con...
