Preferably, above-mentioned middle phase pull rope connects above-mentioned two ground wires, two wire guide ropes and a middle phase pull rope through limp.
Preferably, said lead unfolding process further may further comprise the steps: during through every basic iron tower, will above-mentioned two ground wires and after two wire guide ropes pass coaster, and is connected with above-mentioned limp again, thereby continuation is drawn.
Preferably, the phase preliminary leading rope adopted propeller-parachuting or the dirigible exhibition perhaps manpower exhibition of putting to put during said exhibition was put.
Preferably, said utilize above-mentioned in phase preliminary leading rope exhibition put secondary guiding rope and adopt the manpower exhibition to put, said utilize the exhibition of above-mentioned secondary guiding rope to put once more level guiding rope and utilize the exhibition of the above-mentioned guiding of level once more rope to put to state in the phase pull rope put for the machinery exhibition.
Preferably, above-mentioned middle phase preliminary leading rope is Φ 3.5 high-strength caprone cables, and above-mentioned secondary guiding is restricted and is Φ 10 enlightening Nimas rope, and level is guided to restrict and is the 15 anti-steel wire ropes of turning round once more.
Preferably, above-mentioned ground wire is the GJ-80 cable.
Put two ground wires, two wire guide rope and a middle phase pull rope through exhibition once, this technology can reduce the number of times of the flight of propeller-parachuting, increases work efficiency, energy savings, saving cost, increases fail safe.

Fig. 1 is put the sketch map of middle phase preliminary leading rope for exhibition in the preferred embodiment of lead unfolding process of the present invention.
Fig. 2 is put the sketch map of secondary guiding rope for phase preliminary leading rope exhibition in utilizing in the preferred embodiment of lead unfolding process of the present invention.
Fig. 3 is put the sketch map of level guiding rope once more for utilizing the exhibition of secondary guiding rope in the preferred embodiment of lead unfolding process of the present invention.
Fig. 4 is for utilizing the sketch map of phase pull rope during the exhibition of level guiding rope is put once more in the preferred embodiment of lead unfolding process of the present invention.
Fig. 5 once opens up for phase pull rope in utilizing in the preferred embodiment of lead unfolding process of the present invention puts the sketch map that two ground wires and three-phase conducting wire are restricted with level guiding once more.
[embodiment]
Below in conjunction with accompanying drawing, specific embodiment of the present invention is elaborated.
Put efficient for the exhibition that improves lead effectively, the present invention provides a kind of lead unfolding process, and this technology comprises the steps:
A) phase preliminary leading rope 1 (as shown in fig. 1) during exhibition is put.In the present embodiment, middle phase preliminary leading rope 1 is Φ 3.5 high-strength caprone cables.General technology is that propeller-parachuting (or dirigible) exhibition is put, and the level land that condition is good also can adopt the manpower exhibition to put.Before adopting propeller-parachuting (or dirigible) unfolding process, mainly adopt the manpower exhibition to put.
B) secondary guiding rope 2 (as shown in Figure 2) are put in 1 exhibition of phase preliminary leading rope in the utilization.In the present embodiment, secondary guiding rope 2 is Φ 10 enlightening Nimas ropes, and secondary guiding rope 2 is put in the exhibition of phase preliminary leading rope 1 manpower in the utilization.Middle phase preliminary leading rope 1 is restricted with secondary guiding and is adopted rotary connector to be connected between 2.
C) utilize secondary guiding rope 2 exhibitions to put level guiding rope 3 (as shown in Figure 3) once more.In the present embodiment, level guiding rope 3 utilizes secondary guiding rope 2 machinery exhibitions to put secondary guiding rope 3 for 15 prevents turning round steel wire rope once more.The employing rotary connector is connected secondary guiding rope 2 between 3 with the level guiding is restricted once more.
D) utilize phase pull rope 4 (as shown in Figure 4) during 3 exhibitions of level guiding rope are put once more.In the present embodiment, middle phase pull rope 4 is the 24 anti-steel wire ropes of turning round, and utilizes grade guiding rope 3 machinery exhibitions once more to put middle phase pull rope 4.The employing rotary connector connects between level guiding rope 3 and the middle pull rope mutually 4 once more
E) utilize in phase pull rope 4 exhibition of once draw put left ground wire 5, right ground wire 6, left wire guide rope 7, right wire guide rope 8 and middle phase pull rope 9 (as shown in Figure 5).In the present embodiment, wire guide rope 7,8 is the 15 anti-steel wire ropes of turning round, and middle phase pull rope 9 is prevented turning round steel wire rope for 24, and ground wire is the GJ-80 cable.
In brief; Above-mentioned construction technology is exactly in lead, to open up in the phase coaster to put a guiding rope (preliminary leading rope 1, secondary guiding rope 2,3); The guiding rope (middle phase pull rope 4) of phase in utilizing then; Adopt " one leads five " towing plate (call limp in the following text, as shown in Figure 5), with two ground wires (ground wire 5,6) and three-phase conducting wire with guiding rope (left wire guide rope 7, right wire guide rope 8 reach middle pull rope 9 mutually) disposable put logical." one leads five " limp divides rope during through every basic iron tower on tower; Be connected with " one leads five " limp again after 2 ground wires (ground wire 5,6) and 2 sidelines guiding rope (left wire guide rope 7, right wire guide rope 8) passed coaster; Continue traction then, will guide rope by base and put logical.The advantage of this technology construction is to reduce the number of times of the flight of propeller-parachuting, energy savings, saving cost, increase fail safe.
Adopt the construction of above-mentioned unfolding process that following advantage is arranged: on the one hand, can reduce the powered paragliding number of times, thus energy savings, the security risk that reduces; On the other hand, can reduce the payingoff construction personnel amount, reduce the human cost of engineering.
The above embodiment has only expressed several kinds of execution modes of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement to enforcement of the present invention, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with accompanying claims.
