(3) complete unwrapping wire, cable pulling arrives corresponding steel tower position and is fixed, and pulls down lightweight pull rope and lightweight traction limp.
And, step (1) described lightweight traction limp comprises limp, traction connector, tee connector, suspension bracket and weight, limp is isosceles triangle slab construction, is hinged with a traction connector at the drift angle of limp, and this traction connector plays the pull rope of pulling force for connecting; At the base plate of limp, multiple tee connector is installed uniformly at intervals, in order to when keeping air-towing lines, limp keeps horizontal level substantially, two isosceles base angle positional symmetry of limp are shaped with bolt hole and by having a suspension bracket in two bolts hole, upper end, suspension bracket both sides is packed in limp through bolt hole by stop nut, be lifted with a weight in the middle part of suspension bracket lower end, this weight is positioned at below in the middle part of limp.
And, the suspension bracket above weight is installed with counterweight.
And described tee connector is four or five.
And described traction connector and tee connector are to be prevented turning round connector.
And describedly anti-turn round connector and comprise Connection Block and terminals, the axial one end of Connection Block is arranged on away panel edges, and the axial other end coaxial rotation of Connection Block installs terminals.
And, step (2) in, the pull rope pull rope connector of lightweight tow out front edge of board has a lightweight pull rope, lightweight traction limp rear end multiple tee connectors connect a lightweight pull rope respectively, the final stube cable of every root lightweight pull rope.
And, be connected with secondary pull rope between lightweight pull rope and cable as transition.
Advantage of the present invention and good effect are:
1, the leading unfolding lightweight guide rope that the present invention adopts carries out a point rope, therefore the unfolding coordinating the lightweight of lightweight guide rope traction limp to carry out pull rope has been designed and produced especially, solve the process links of manually putting pull rope and point rope, promote operating efficiency, and change the step of artificial ground distributor rope into high-altitude traction point rope, solve the problem of crossing over ground obstacle time-division rope difficulty.
2, expected result of the present invention can combined innovation wound effect practical engineering application Criterion metallization processes flow process and working specification so as Efficiency in Buildings in Tianjin Area expand application.

Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of transmission line guide rope traction unwrapping wire technique, step is as follows:
(1) prepare, in conjunction with drawn pull rope force-bearing situation, the specification of carrying out lightweight traction limp is determined, is made;
What force analysis Water demand calculated electric traction rope rope at different levels passs the power of scooping out;
The structure of lightweight traction limp is see Figure of description 1 to 4, comprise limp 1, traction connector 2, tee connector 3, suspension bracket 5 and weight 6, limp is isosceles triangle slab construction, be hinged with a traction connector at the drift angle of limp, this traction connector plays the pull rope of pulling force for connecting; Be provided with multiple tee connector uniformly at intervals at the base plate of limp, conventional unwrapping wire technique uses one point of four or one points of five structure, and tee connector is for connecting trailed lightweight pull rope;
In order to when keeping air-towing lines, limp keeps horizontal level substantially, two isosceles base angle positional symmetry of limp are shaped with bolt hole and by having a suspension bracket 5 in two bolts hole, upper end, suspension bracket both sides is packed in limp through bolt hole by stop nut 4, a weight is lifted with in the middle part of suspension bracket lower end, this weight is positioned at below in the middle part of limp, keeps limp center balance; According to actual working environment situation, the suspension bracket above weight is installed with counterweight 7, increases the quality of weight.
Reversing to prevent pull rope causes limp to overturn, and described traction connector and tee connector are to be prevented turning round connector, prevents that turning round connector comprises Connection Block 8 and terminals.The axial one end of Connection Block is arranged on away panel edges, and the axial other end coaxial rotation of Connection Block installs terminals, and terminals are used for pull rope and connect, even if pull rope drives terminals to rotate, limp can not be caused to overturn.
