Description
Technical field
The present invention relates to a kind of hanging tool, hangs insulation on overhead transmission line conductor more particularly to one kind
The instrument of rope ladder.
Background technology
At present, in service works such as power industry overhead transmission line replacing insulator under electrified, repairing wire, dismounting foreign matters
It is required to suspension insulated flexible ladder and enters side of wire operation, can effectively hang insulated flexible ladder be the pass for determining enter side of wire operation
Key.The method of conventional suspension insulated flexible ladder has two kinds：One kind is to hang somersault coaster method, and operating personnel carries insulating cord, somersault
Coaster, insulating bar rod-rising tower to cross-arm are hung the somersault coaster with insulation ropes to wire using action bars,
Ground staff coordinate it is lower insulated flexible ladder is hung to wire by somersault coaster, after directly being removed using action bars during disengaging certainly
By falling bodies to ground, but as voltage class raises, operation pole length constantly increases, and is hung on tower, removes somersault coaster hardly possible
Degree is bigger, and removes somersault coaster freely falling body and easily damage instrument.Another kind is direct shooting rope method, and operating personnel is on the ground
Wire was thrown by a small shooting rope, small shooting rope draws insulating cord across wire, by drawing insulating cord directly to lift insulated flexible ladder
Insulated flexible ladder on wire is hung, but abrasion of the wire coarse in lifting, whereabouts insulated flexible ladder to insulating cord is very serious, and
Ground operation personnel is needed to coordinate, labor intensity is big.The outstanding of insulated flexible ladder can not be effectively completed using both the above method
Hang.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art to provide a kind of instrument of live wire suspension insulated flexible ladder,
It is simple and practical, overcome the deficiencies of work high above the ground difficulty is big, tool damage is serious, operation effectiveness is difficult to ensure that, solve livewire work
During suspension insulated flexible ladder the problem such as waste time and energy, substantially increase efficiency, reduce operating risk.
The present invention includes suspension dynamic ropes, departs from dynamic ropes, it is characterised in that also including coaster gib head, connecting hole, disengaging
Arm-tie, guide plate, pin, connecting bolt, connecting screw, strap, insulating block；Described tackle hook overhead fluting is beaten
Connecting hole I, the interior insertion of groove depart from arm-tie, depart from arm-tie and fixed by pin I, and slotted head beats connecting hole II, inserts and leads in groove
Corbel back slab, guide plate use pin II axis connection；Described guide plate is connected with suspension dynamic ropes by connecting hole II, departs from arm-tie
It is connected by connecting hole I with departing from dynamic ropes；Described coaster gib head by strap, connecting bolt, connecting screw with absolutely
Edge pulley connects.
As shown from the above technical solution, light when in use, flexible, safe and reliable, practical, easy to operation, energy of the invention
Enough overcome the shortcomings of in traditional work method solve to hang the problem that insulated flexible ladder is wasted time and energy during livewire work, significantly
Reduce the labor intensity of operating personnel and the risk of livewire work.

Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the present invention includes the 1A of connecting hole I, the 1B of connecting hole II, and disengaging arm-tie 2, the 3A of pin I, pin II 3B,
Coaster gib head 4, guide plate 5, strap 6, connecting bolt 7, connecting screw 8, insulating block 9, dynamic ropes 10 are hung, departed from dynamic
Power rope 11 etc..
The described top-slitting of coaster gib head 4 plays the 1A of connecting hole I insertions and departs from arm-tie 2, is fixed by the 3A of pin I, makes to take off
It can not be rotated from arm-tie 2；Slotted head beats the 1B of connecting hole II insertion guide plates 5, and with pin II 3B axis connections, i.e., guide plate 5 can
With around pin II 3B flexible rotatings.
With reference to shown in Fig. 2, described coaster gib head 4 passes through strap 6, connecting bolt 7 and connecting screw 8 and insulation
Pulley 9 connects, and insulating block 9 can reliably rotate around connecting screw 8.
Described connecting hole 1A dockingundockings dynamic ropes 11, the described 1B connections of connecting hole II suspension dynamic ropes 10 are described
Insulating block 9 in insulating cord be directly connected with insulated flexible ladder.
When hanging insulated flexible ladder, after suspension dynamic ropes 10 were thrown wire, traction suspension dynamic ropes 10 hang coaster gib head 4
Hang on wire, then pull the insulating cord in insulating block 9 to lift insulated flexible ladder and hang to wire.During disengaging, pass through
The insulating cord in insulating block 9 is pulled to complete the disengaging of insulated flexible ladder, the disengaging power then connected by being pulled off arm-tie 2
Rope 11 can be easily accomplished the disengaging of coaster gib head 4 and live wire.
