Description
Technical field
The present invention relates to overhead transmission line maintenance technique field, particularly to a kind of overhead earth wire lifter and
It lifts installation method.
Background technology
Aerial earth wire is the device for protecting overhead transmission line to exempt from lightning attack.In order to improve the safety of circuit operation
Property, aerial earth wire is typically all to be erected above protected wire.When there is thundercloud to ground discharge in side on the line, lightning
Passage easily hits aerial earth wire first, lightning current is entered the earth, to protect the normal power transmission of wire.Meanwhile aerial earth wire is also
There is electromagnetic shielding action, when thundercloud is to ground discharge near circuit, it is excessively electric that the caused lightning induction on wire can be reduced
Pressure.Therefore aerial earth wire must firmly be connected with tower grounding device, to ensure reliably lead lightning current after being struck by lightning
Enter the earth.Important transmission line of electricity typically uses two aerial earth wires that protected wire is all placed in its protection domain
It is interior.
Function of the aerial earth wire due to not bearing conveying electric current, so being formed more using steel strand wires.Also some transmission lines of electricity
Using good conductor ground wire, i.e., the aerial earth wire made of aluminium alloy or aluminium Baogang wire.This ground wire electric conductivity is preferable, can be with
Improve multi-line power transmission performance, mitigate the interference to adjacent communication line.
Power transmission line overhead ground wire defect happens occasionally, when stranded needs replacing occurs in aerial earth wire or is inspecting periodically ground
During line wire clamp, workmen needs to lift by crane aerial earth wire, unclamps ground wire wire clamp, is changed or Inspection.Due to shaft tower knot
Structure limits, and lifting by crane the capstan winch of aerial earth wire does not have suitable hanging point, and generally existing Heave Here is too low, lifts by crane the problem of difficult.
China Patent No. is that " 2014103248189 " disclose a kind of " overhead earth wire lifter ", the tray in scheme
Upper setting bobbin, bobbin spanner is connected on bobbin, rope is wrapped on bobbin, the exit connection thread-lifting hook of rope, tray
Upper one end for being flexibly connected shrinking connecting-rod, the other end connection deck of shrinking connecting-rod, deck are provided with governor motion.Tray is
Regular polygon.Bobbin is square shaft.It is flexibly connected between tray and shrinking connecting-rod by bolt and nut.Deck is right-angled U.Adjust
Saving mechanism is：Pad I and pad II is symmetricly set on the inner surface of deck, pad I connection set screws.The program aims to solve the problem that
The artificial line efficiency that carries is low, the problem of potential safety hazard be present.
When overhead earth wire lifter works, more than ten meters of height need to be lifted with insulating cord by staff on tower, be then mounted to
On aerial earth wire support, because line lifter deadweight is larger, whole erection ＆ lift process is also hidden in the presence of surprisingly coming off than relatively time-consuming
Suffer from.
The content of the invention
It is an object of the invention to provide a kind of overhead earth wire lifter and its lifting installation method, for lifting by crane aerial earth wire
