SS03 when the hoop (513) moves up to a certain distance, the fastening screw (514) on the hoop (513) is screwed by an external tool, so that the hoop (513) is tightly attached to the surface of the power column, at the moment, a maintainer holds the power column to enable the hip to leave the seat (501), and the electric telescopic piece (506) drives the arc-shaped fixing hoop (507) to be separated from the surface of the power column;
the SS04 drives the arc-shaped fixing hoop (507) to move upwards along the power column by utilizing the elastic restoring force action of the power-assisted elastic element (515), and simultaneously drives the arc-shaped fixing hoop (507) to move upwards by utilizing the safety rope at the waist of the maintainer;
SS05 when the arc fixing hoop (507) moves up a certain distance, the two arc fixing hoops (507) are tightly attached to the surface of the electric power column by the electric telescopic piece (506) again, the maintainer sits on the seat (501) again, and the fastening screw (514) is slightly loosened to enable the hoop (513) to be attached to the surface of the electric power column to slide;
SS06 also operates in a manner that allows service personnel to reach the desired service height.
