Ultra-high-tension power transmission line generally has three-phase conducting wire and two ground wires, and double back tower circuit also has three-phase conducting wire and a ground
Line, by the use of 50 grades of non-outlet phase conductor or ∮ or more ground wire as the back-up protection of outlet phase conductor operating personnel, i.e., in non-outlet
Mutually or ground wire hangs up anti-fall device described in the utility model, protection rope is fastened, operating personnel's peace is led on the link of frame downward
It takes entirely；Upper and lower pulley on apparatus for suspension is fixed on same longitudinal axis, and two pulley rooms are away from can pass through frame downward both sides
Sliding slot be adjusted, big spacing facilitates being put into for various conducting wire, then by conductor clamping during small spacing, possesses blocking function, two
Pulley rotation flexibly, will not phase mutual friction.Under normal operation, pulley is in minimum spacing state, and conducting wire is in two pulleys
Between, possess 360 ° of functions without interim card, job-hopping；Protection rope automatically retractable between pulley and operating personnel, rope lengths
It can change with grounded-line phase spacing and change, speed difference device starting protection operating personnel exempts from wire fracture or accidental falling
It is hurt.
The beneficial effects of the utility model：The utility model has simple in structure, easy to manufacture, easy to use, slip spirit
The advantages that living, package unit is simple mechanical structure, and principle is simple, easy to use；Device can be free under nominal situation
It slides, the gravity of the simply single adult born under maximum conditions, so as to reach anti-fall purpose, securely and reliably；This practicality is new
Type can be as personnel's back-up protection measure of the overhead lines outlet operation such as 35~220kV transmission lines of electricity, ADSS optical cables, and purposes is wide
It is general.
