Abstract
The invention relates to a ground wire auxiliary wiring rod, which comprises a hollow insulation wiring rod body, and is characterized in that a telescoping rod is inserted in the insulation wiring rod body, and a fixed pulley is provided at the top of the telescoping rod through a wheel carrier. because that a telescoping rod is provided on the insulation wiring rod body, the operation scope of the operators can be greatly prolonged, the ground wire can be conveniently hanged by the operators, and the work efficiency is increased. Simultaneously, the safe distance between the operators and electrically charged equipment can be guaranteed, and the incidence rate of security incidents can be greatly reduced.
Description
Technical field
The utility model relates to the electric operating auxiliary equipment, particularly a kind of earth connection auxiliary connection bar.
Background technology
Power transmission sequence power failure operation for guaranteeing operating personnel's handling safety, need articulate earth connection when hanging earthing conductor.The hand-held insulating bar of operating personnel makes end in contact earth connection wire clamp under the earth connection when articulating, and under the triggering of earth connection gravity effect, the earth connection wire clamp clamps earth connection.
When hanging earthing conductor, particularly when the wire jumper (line draws) of the corner pole interior angle side of voltage levels is gone up hanging earthing conductor, because the corner pole size is big, the corner pole corner is limit, make this side wire jumper be positioned at the cross-arm outside, insulating bar length is too short, and operating personnel are difficult to end in contact earth connection wire clamp under the earth connection.The ground wire hitching difficulty, inefficiency.In addition, owing to articulate difficulty, operating personnel pass by closely because of the distance live line can cause the personal safety accident.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of earth connection auxiliary connection bar of being convenient to ground wire hitching, high efficiency, can improving the handling safety coefficient.
The utility model is achieved in that
A kind of earth connection auxiliary connection bar comprises that the insulation joint bar body of hollow, its special character are, is fitted with expansion link at insulation joint bar body, is provided with fixed pulley on the expansion link top by wheel carrier.
Between described expansion link and insulation joint bar body, be provided with locking device, to avoid expansion link withdrawal when putting down earth connection.
Described locking device is the spiral retaining mechanism.
But be hinged with the insulated wire catch of folding on the described wheel carrier, come off from the fixed pulley groove to prevent insulated wire.
The beneficial effects of the utility model are:
Because insulation joint bar body is provided with expansion link, can prolong operating personnel's opereating specification greatly, handled easily personnel hanging earthing conductor has improved operating efficiency.Simultaneously, guarantee the safe distance between operating personnel and the charging equipment, improved the handling safety coefficient, greatly reduced the incidence of personal safety accident.
