and step six, continuing to descend the annular operating platform until the annular operating platform reaches the construction position: the elevator is used for driving the steel wire ropes connected with the hoisting point members of each operation platform to move downwards along the axial direction of the tower drum until the construction positions of the tower drum and the blades, and the annular operation platform assembly can also rotate along the outer wall of the tower drum along with the rotation of the top position of the tower drum of the nacelle cover, so that the maintenance and repair and cleaning work of any position of the whole tower drum are realized;
step seven, lifting the annular operating platform and recovering the radius after the construction is finished: after the maintenance, repair and cleaning operation of the tower barrel and the blades are finished by workers, the steel wire ropes connected with the hoisting point parts of the operation platforms are driven by the lifter to lift upwards along the axial direction of the tower barrel, and the workers can reduce the overall diameter by using the long circular hole extending structures with bolts on the first assembly, the second assembly and the third assembly of the operation platforms along with the increase of the lifting height and the narrowing of the diameter of the tower barrel, so that the annular operation platform assembly is reset;
step eight, retracting the guardrails to return to the cabin and closing the window: when the annular operating platform assembly is lifted upwards along the axial direction of the tower barrel to a position close to the cabin cover, workers lower the guardrail, withdraw from the position of the boss through the window and withdraw from the annular operating platform assembly to the inside of the cabin cover;
ninth, installing and fastening each operation table fixing assembly in the cabin cover: after all the workers are evacuated, the elevator is used for driving the steel wire ropes connected with the lifting point pieces of each operation platform to lift upwards along the axial direction of the tower barrel, the annular operation platform assembly is attached to the bottom of the cabin cover, the lifting point pieces of each operation platform are inserted into the cabin cover splicing pieces, and the joints of the lifting point pieces of each operation platform and the cabin cover splicing pieces are fastened through bolts through the key pins, so that the whole set of operation is completed.
