The technical problem to be solved by the present invention is to：Overcome the deficiencies of the prior art and provide a kind of reasonable design, it is safe and reliable,
Work efficiency is high and saves the climbing personal safety guard method of mobile power line shaft tower and the dress of working at height personnel's muscle power
It sets.
The technical scheme is that：
A kind of mobile power line shaft tower climbing personal safety guard method, chooses unmanned plane, and under the fuselage of unmanned plane
End setting hook and electromagnet；Setting hook is arranged closed type self-lock rod in the open end of hook, is arranged in the lower end of hook
Hanging ring is arranged in the upper end of hook in fixed pulley, and the upper end of hanging ring is arranged iron plate, hanging ring lower end is provided with stepped hole, stepped hole
The elevating lever of irony is placed in the inside, and the lower end of elevating lever connect by unlock rope with self-lock rod, by the hook of unmanned plane with
Hook can be articulated on aerial earth wire by the cooperation of the hanging ring of hook, then by the iron plate of the electromagnet of unmanned plane and hook,
The cooperation of elevating lever, unlock rope, self-lock rod can remove hook from aerial earth wire, will be exhausted by unmanned plane and traction rope
Edge bearing rope is passed through from fixed pulley, and the one end for the bearing rope that insulate is fixed on shaft tower or bracing wire fixed point by self-lock protection device
On, the other end for the bearing rope that insulate and the protection band connection of operating personnel, insulation bearing rope protect the operating personnel to climb.
One end of self-lock rod and the side at hooking slits are hinged, and torsional spring is arranged in hinged place, and self-lock rod is made to be in normal
The other end of closed state, self-lock rod is placed in the limiting slot of the setting of the other side at hooking slits, and opening is made to be in normally closed
State.
Unmanned plane uses multiaxis rotary wings unmanned plane, supporting leg to use hydraulic shock-absorption formula structure, also, in the most lower of supporting leg
End setting wear-resisting head, prolongs the service life.
One directive wheel is set on the inside of hook, unlock rope is passed through from directive wheel, and self-lock rod is enable to facilitate rotation, with
Open the opening of hook.
When installation hook, electromagnet no power does not have magnetic force, and handling will be linked up with to aerial earth wire by hook and hanging ring
On, unmanned plane declines, and pushes self-lock rod open by gravity, and aerial earth wire is made to enter hook inner cavity, and when dismounting, electromagnet is powered,
Magnetic force makes electromagnet be bonded together with iron plate, and iron plate adsorbs elevating lever in turn, so that elevating lever is increased, elevating lever passes through unlock rope
By self-lock rod pull-up, the opening of hook is opened, unmanned plane rises again, and hook is detached from aerial earth wire.
A kind of mobile power line shaft tower climbs personal safety protector, including unmanned plane and hook, it is described nobody
The fuselage lower end setting hook and electromagnet of machine, the open end of the hook are arranged closed type self-lock rod, under the hook
Hanging ring is arranged in the upper end of end setting fixed pulley, the hook, and iron plate is arranged in the upper end of the hanging ring, and the hanging ring lower end is provided with
