Description
Technical field
The present invention relates to power equipment lowering or hoisting gear, particularly relate to a kind of aerial earth wire lowering or hoisting gear.
Background technology
Aerial earth wire is also called lightning conducter, introduces the earth for the electric current produced by thunder and lightning, in case
The electric current that only thunder and lightning produces destroys transmission facility.In using for a long time, owing to being used for clamping
Aerial earth wire is also suspended in the wire clamp in high-altitude and can gradually relax, so not adopting by aerial earth wire
In the case of the good locking measure of wire clamp, aerial earth wire can misplace with wire clamp.When built on stilts
When line misplaces with wire clamp, the supporting point of aerial earth wire can change, and aerial earth wire also can be with line
Folder phase mutual friction.If things go on like this, the more fragile internal structure that can make aerial earth wire is damaged
Wound, even can make aerial earth wire disconnect.Accordingly, it would be desirable to aerial earth wire is overhauled.
According to the regulation of " overhead transmission line operating standard " (DL/T741-2010), carrying out
The wire clamp of aerial earth wire it is switched on, to check that abrasion, disconnected stock, broken stock, electric discharge are burnt during maintenance
Faults such as wound and carry out fault restoration.In existing inspection operation, a kind of mode of operation is
Operator substitute wire clamp with shoulder and support aerial earth wire to unclamp wire clamp and adjusting wire clamp
Position, this mode of operation can make operating personnel's shoulder injuries, and safety coefficient is low.Another kind of
Mode of operation be utilize chain block substitute wire clamp to lift aerial earth wire in case open wire clamp and
Repairing aerial earth wire, the instrument that this mode of operation uses takes up room greatly, and operating process is complicated,
The operator needed are many.Also having a kind of mode of operation is not exclusively to unclamp wire clamp to use spanner
Beaing wire clamp makes wire clamp enter tram, and this mode of operation easily damages aerial earth wire, wink
Between impulsive force steel tower also can be made to produce rock thus affect operation safety.As can be seen here, above-mentioned side
The safety of method can not get ensureing, overhaul efficiency is low.
