Abstract

The utility model discloses a lead hanging hook for an earth wire, which is used in field operation and belongs to the technical field of maintenance and overhaul tools of power transmission lines. The lead hanging hook comprises a line-to-ground wire clamp, an insulating operation bar, an earth lead and an earth end wire clamp; a rotating shaft with a locking device is arranged between the line-to-ground wire clamp and the insulating operation rod; a gear-shaped connecting device is arranged at the extending end of the rotating shaft and is used for connecting the line-to-ground wire clamp with the insulating operation rod; the line-to-ground wire clamp and the insulating operation rod are fixed by fastening bolts; the rotating shaft with the locking device is embedded and inserted into a clamp back of the line-to-ground wire clamp; the lower end of the line-to-ground wire clamp is an earth lead end fixedly connected by a fastener; and the earth lead end is connected with the earth lead which is connected with the earth end wire clamp.

Description

A kind of earth connection wire hook

Technical field

The utility model relates to electric power transmission line Maintenance and Repair technical field of tools, a kind of earth connection wire hook that uses when relating in particular to field work.

Background technology

When electric power transmission line maintenance, maintenance or field work, existing earth connection great majority all are two kinds of the earth connections of two house tension formulas and bolt type.In order to protect the staff to need often will to carry additionally and retract earth connection thereby seem very important in the rear and front end, job site with earth connection wire hook hanging earthing conductor.For example the leading-out terminal to circuit adds hanging earthing conductor in transformer station, if the gradient of outlet is less or level, existing earth connection just can satisfy job requirement.If but all there is certain gradient in transformer station's outlet; perhaps this section has scissors crossing; perhaps be located in high mountain area operation; add hang up just cumbersome because there is the gradient, though can hang up with two house tension formulas hooks; but if blowing add the gravity of self will slippage; and not tight phenomenon can appear twisting with the helical path hook, and also be the incorrect method that adds hanging earthing conductor, can not well play a protective role.When strain section work adds hanging earthing conductor; safest protection is exactly at the two ends of strain insulator shaft tower hanging earthing conductor; be that existing earth connection can only be hung on the front and back two basic shaft towers of working point; personnel are disperseed and increase the work on the spot amount; adding hanging earthing conductor in work in the past can only hang on the drainage thread; if on drainage thread, work or when changing strain clamp; existing hanging earthing conductor but can only add on the drainage thread that hangs over the work rear; obviously the staff has just lost the protection of earth connection, exists that to articulate earth connection not firm; remove problems such as trouble and protection range are not enough.

The inventor finds that in practice existing earth connection hook can not satisfy the needs of line maintenance maintenance work, has therefore designed a kind of novel grounded line wire hook, can satisfy the requirement of correct hanging earthing conductor under the various situations.

Summary of the invention

The purpose of this utility model provides a kind of novel grounded line wire hook, overcomes the above-mentioned problems and shortcomings that exist with solution.

The technology solution that realizes the utility model purpose is such: a kind of earth connection wire hook is made of line-to-ground wire clamp, insulation hook stick, earth lead and earth terminal wire clamp, the rotation axis that one band locking device is arranged between circuit earthing clamp, insulation hook stick, the extended end of the rotation axis of band locking device have the jockey of band gear-like that line-to-ground wire clamp and insulation hook stick are linked together and are fixed by fastening bolt; The rotation axis intercalation of band locking device is at the wire clamp back at the circuit earthing clamp, and line-to-ground wire clamp lower end is that the earth lead end is connected with earth lead by the fixedly connected earth lead end of securing member, and earth lead is connected with the earth terminal wire clamp.

The utility model compared with prior art has following advantage: the advantage of earth connection wire hook is can 360 ° of rotary manipulations at vertical direction by fixed being improved to original earth connection wire hook.In the electric power transmission line Maintenance and Repair are used, articulate and remove all very convenient, and use can satisfy under the various situations especially mountain area, hillside fields operation the time, solved the variety of issue of transmission line when using ground connection, saved staff's workload, also improved coefficient of safety, convenient to operation, shortened interruption duration, improved operating efficiency.
