s2, suspending the fan main frame right above the fan main frame turnover device, aligning a main frame main shaft port to one side of a driven rotating shaft (2), moving the main frame downwards until the main frame is at the same height with the driven rotating shaft (2), setting the distance from a sliding block (111) to a frame fixing plate through a distance adjusting button according to the model of the main frame, opening a switch button, measuring the distance from the driven rotating shaft to the frame fixing plate in real time by an infrared distance measuring instrument (104) and feeding the distance to a touch screen controller (103), feeding a signal back to an electric push rod (112) by the touch screen controller (103), retracting the electric push rod (112), pulling the sliding block (111) to move towards the direction close to the frame fixing plate on a track, assembling a mounting shaft on the driven rotating shaft with a main frame main shaft hole, and abutting against the outer side of the main frame main shaft port by a shaft (202) and a shaft step formed by the mounting shaft (201), the infrared distance measuring instrument (104) feeds back a distance signal to the touch screen controller (103), the switch is automatically closed, the electric push rod (112) stops moving, the sliding block is kept still, and the sliding ring (401) stops moving on the horizontal cross beam (4) along with the suspension rod;
meanwhile, the other end of the main frame is just propped against the frame fixing plate, the main frame is horizontally rotated, so that a bolt hole on the main frame is correspondingly matched with a mounting hole of the frame fixing plate in position and is fastened by a bolt;
s3, the main frame is completely fixed on the fan main frame turnover device, the servo motor (504) is started, the servo motor (504) rotates in the positive direction, after the speed is reduced by the speed reducer (503), the rotary motion is transmitted to the connecting shaft (502), the connecting shaft and the fixed main frame form a whole, the main frame and the connecting shaft (502) rotate synchronously, the driven rotating shaft rotates, the servo motor stops working after rotating 180 degrees of travel, and the main frame synchronously finishes the action of turnover by 180 degrees;
s4: when the main frame after turning over is dismounted, an external lifting rope is used for suspending the main frame; setting the end point position of the driven rotating shaft to the maximum position far away from the rack fixing plate through a distance adjusting button on a touch screen of a touch screen controller;
after a switch button is turned on, an infrared distance meter (104) measures the distance from a driven rotating shaft to a rack fixing plate in real time and feeds the distance back to a touch screen controller (103), the touch screen controller (103) feeds a signal back to an electric push rod (112), the electric push rod (112) does stretching motion, a sliding block (111) is pushed to move on a track in the direction far away from the rack fixing plate, and a sliding ring (401) slides on a horizontal cross beam (4) along with a hanging rod until a mounting shaft on the driven rotating shaft is separated from a main rack main shaft hole;
then the main frame and the bolts in the mounting holes of the rack fixing plate are disassembled and separated; the main frame and the fan main frame turnover device are completely separated from each other by the turnover method, and the main frame is lifted by an external lifting rope;
and S5, stopping the driven rotating shaft (2) at the maximum position away from the main frame fixing plate, and waiting for the main frame to be installed again and turning over.
