Description
Technical field
The present invention relates to power line protection field, refer in particular to the construction method of a kind of tension type power line protection net.
Background technology
The development built along with electric power energy, powerline network cloth and the earth, become economic, society and life breath manner of breathing
The neural venation closed.During newly-built electric transmission line erection lead wire and earth wire, the leap that has a power failure intersects power line construction will be to local warp
Ji and people's life bring inconvenience, electrical network reliable power supply to concern national economy and social public security.For a long time, do not stop
Electricity crosses over intersection power line construction method, worldwide lacks effective solution.
Therefore, this is made further research by the present inventor, develops a kind of tension type transmission line protection system, this case by
This produces.
Summary of the invention
It is an object of the invention to provide the construction method one tension type electricity of a kind of tension type line protection
The construction method of line of force road catch net, reaches newly-built circuit and leads ground aerotow and do not affect and be spanned power circuit operation.
To achieve these goals, technical scheme is as follows:
The construction method of a kind of tension type line protection, is being provided above tension type transmission line of electricity across power circuit
Protection device, tension type line protection includes catch net, carrying rope, wave wind rope, earth anchor system, and wherein catch net sets
Putting by above power circuit, between N tower and N+1 tower, N tower and N+1 tower are across the ferrum of power circuit
Tower；Catch net by carrying rope, wave wind rope, earth anchor system carry arrange, by project situation set carrying rope cross-arm hanging point position,
Carrying rope ground angle, wave wind rope ground elevation, catch net size and height, then calculate the theory of each rope in rope force system
Value, fixing-line device one that earth anchor system includes being sequentially connected with, lever hoist, draw-bar donamometer, earth anchor.
Described construction method comprises the steps:
1) first strop is pulled out from draw drum, through the suspension pulley being arranged on N steel tower, then strop is hung over
On the line hanging mechanism of multi-rotor aerocraft, after aircraft arrives N+1 steel tower, by radio control, guiding becket bridle is taken off
From, then end is through the suspension pulley being arranged on N+1 steel tower to ground, strop and carrying rope at N+1 steel tower
Or endless rope connects, then returning traction conductor rope on N Ta Chu ground, carrying rope, endless rope set up by root；Carrying rope is at N ferrum
Being connected to earth anchor system through suspension pulley on tower and N+1 steel tower, endless rope does with the ferrum of both sides and ties up tower anchor temporarily；
2) being lived by carrying line anchor with fixing-line device two on N tower, earth anchor system freed by carrying rope, returns back out the suspension pulley on tower,
N tower ground fallen by tail rope, the most successively braiding nettle nose-ring is penetrated carrying rope, is then threaded back through carrying rope on tower hanging sliding
Taking turns, carrying rope is tightened up on ground, and mesh grid promotes and is suspended on fixing-line device two and suspension pulley room, and then carrying rope connects earth anchor system
System, continues to tighten up spooler, after carrying rope ground is painstaking, releases fixing-line device two on tower；
3) after mesh grid hangs up carrying rope, then endless rope tangles catch net medial ends, and at N+1 tower, endless rope is received
Line, mesh grid is pulled to protection zone and moves, at mesh grid end continuous extension endless rope and wave wind rope, when catch net arrives specific bit
Putting, then circulation rope belt tension on the tower of both sides is tied up tower and is fixed；
4) mesh grid end wave wind rope connects earth anchor system, and opposite side is risen wave wind rope hook on blanking bar by multi-rotor aerocraft and catches
Carrying rope, then wave wind rope is connected with earth anchor system, and after 4 unrestrained wind ropes hang up properly, regulation spooler applies tension force, and catch net is opened
Open, make about catch net and work as position, apply carrying rope downforce simultaneously；
5) regulation carrying rope, the spooler of wave wind rope earth anchor system, observe draw-bar donamometer reading, meet design setting, with
Time check protection net height be spanned power circuit spacing compliant requirement, then various places anchor point specify special messenger guard；
6) after new line stringing completes, remove catch net device in time, first free wave wind rope earth anchor system, fake is inserted in wave wind
Rope, is then hooked by multi-rotor aerocraft rope and holds fake rising, and fake impulsive force hooks wave wind rope to depart from and carries rope, front and back repeats
4 times, wave wind rope departs from carrying rope；
7) with endless rope, mesh grid being pulled to N tower, on tower, carrying rope outside mesh grid lived by fixing-line device anchor, unties earth anchor system
Carrying end portion, unloads mesh grid from carrying rope；
8) at N tower, carry cheese circle inside fixing-line device and hang on endless rope, unload fixing-line device, receive on N+1 Ta Chu ground
Cage carrying rope；
9) finally endless rope is removed by multi-rotor aerocraft.
After using such scheme, the present invention compared with prior art, has the advantage that
(1) raw material of catch net is ultra high molecular polyethylene fibrage rope, has high intensity, low elongation, low quality and electricity
Gas insulating properties, arrange wave wind rope at catch net corner, are applied with catch net vertical force, and this power can offset accident wire pendant net
Pressure, it is to avoid catch net is encountered protected electric lines of force by accident wire pendant net；(2) carrying rope is arranged at the cross-arm strong point flexibly
Conveniently, it is to avoid use additional support crossbeam, catch net, after ground rope nose-ring penetrates carrying rope, then carries rope lift-off, circulation
Rope danish seine, unmanned vehicle set up the operating procedures such as wave wind rope in the air, reduce personal height operation intensity and risk；(3) protection
Net rope tension force is arranged by accident situation value of calculation, safe and reliable；(4) catch net installing, dismounting can be spanned electric lines of force
Carry out under the not power-off condition of road, improve efficiency of construction and social benefit, be environmental protection construction method.
