Further improvement of the present invention is: between the first side wall and the second sidewall, by bearing pin, be provided with road wheel, walking mechanism realizes motion on transmission pressure by road wheel.
Further improvement of the present invention is: in described step d), ground staff observes the position of insulating barrier breakage by telescope.
Further improvement of the present invention is: in described step e), ground staff completes the operation of cutting off connecting line as follows:
E1) get a scissors and an expansion link, a handheld terminal of scissors is fixed on to the top of expansion link;
E2) bolt one insulating cord on another handheld terminal of scissors, insulating cord is walked around from expansion link top, then extends to the handheld terminal of expansion link;
E3) the hand-held expansion link of staff, adjusts the length of expansion link, and connecting line is entered in the cutting edge of scissors at expansion link top;
E4) pull insulating cord to make the cutting edge of scissors closed, cut off connecting line.
Further improvement of the present invention is: in described step e), ground staff hooks and picks hook taking with the expansion link of hook with a top, thereby walking mechanism is taken off.
Owing to having adopted technique scheme, the technological progress that the present invention obtains is as follows:
The present invention is simple and efficient, time saving and energy saving, by a walking mechanism is installed on transmission pressure, the pull rope that walking mechanism is pulled by staff on ground provides power, and side buckle-type insulating tape is pulled to the breakage of transmission pressure insulating barrier, solved the technical problem that in conventional art, the wire insulation between two electric poles must rely on crane to repair, significantly reduced construction cost, and while adopting this method to repair, do not rely on main equipment, instrument is easy to carry, flexible operation mode, there is speed fast, efficiency is high, the advantage that fail safe is good.
