The method is used for fixing the flat cantilever insulator and the inclined cantilever insulator.
In this step, the insulator positioning member 700 and the fine adjustment device 120 are adjusted to align the single-lug connecting hole of the insulator with the positioning pin 704, so as to position the insulator.
(3) And assembling the wrist arm tube. After the insulators are installed and fixed, the cantilever pipes of the inclined cantilever and the flat cantilever which are connected together in a rotating mode at the rear ends are placed in the corresponding cantilever pipe clamping pieces, then the cantilever pipes are inserted into the corresponding insulator connecting holes, the hydraulic valve group 113 is operated to supply power to the oil cylinder, and the wrist pipe clamping pieces 550 are enabled to clamp the wrist pipes.
In this step, if the distance between the insulator holder and the cantilever tube holder needs to be adjusted, the displacement adjustment is performed by pushing the cantilever tube holder to slide on the lateral translation assembly 600, and after the displacement is completed, the position is fixed by a fixing device provided on the third sliding portion 610 at the lower portion of the insulator holder, the fixing device includes, but is not limited to, a bolt passing through the third sliding portion 610, and the bolt restricts the movement between the third sliding portion 610 and the fourth sliding portion 620 by screwing the bolt.
Meanwhile, the lower part of the clamping piece is flexibly connected, so that fine adjustment in any direction is performed by means of a lever principle, and the positioning of the single-lug connecting hole of the cantilever insulator and the installation of the cantilever support between the two wrists are more flexible.
(4) And adjusting the shape of the wrist arm. And (4) adjusting the shape of the wrist arms by combining the drawing, and finally fixing the wrist arm support between the two wrist arms.
