In view of this, be necessary to provide a kind of lead unfolding process that exhibition is put number of times, increased work efficiency that reduces.
A kind of lead unfolding process may further comprise the steps: traction rope in the unfolding; And utilize above-mentioned middle traction rope once to tract two ground wires, two wire guide ropes and a middle traction rope.
Preferably, above-mentioned middle traction rope connects above-mentioned two ground wires, two wire guide ropes and a middle traction rope by limp.
Preferably, described lead unfolding process further may further comprise the steps: when every basic iron tower, will above-mentioned two ground wires and after two sideline guide ropes pass coaster, again be connected limp and connect, thereby continue to draw.
Preferably, described lead unfolding process further may further comprise the steps: phase preliminary leading rope in the unfolding; Utilize above-mentioned middle phase preliminary leading rope to unfold secondary guide rope; Utilize again level guide rope of above-mentioned secondary guide rope unfolding; And utilize above-mentioned again level guide rope to unfold above-mentioned middle traction rope.
Preferably, the phase preliminary leading rope adopts propeller-parachuting or dirigible unfolding or manpower unfolding in the described unfolding.
Preferably, described utilize above-mentioned in the phase preliminary leading rope unfold secondary guide rope and adopt the manpower unfolding, described utilize above-mentioned secondary guide rope unfolding again the level guide rope and utilize above-mentioned again level guide rope unfolding above-mentioned in traction rope unfold for machinery.
Preferably, above-mentioned middle phase preliminary leading rope is Ф 3.5 high-strength caprone cables, and above-mentioned secondary guide rope is Ф 10 enlightening Nima ropes, and a level guide rope is the 15 anti-steel wire ropes of turning round again, and above-mentioned middle traction rope is the 24 anti-steel wire ropes of turning round.
Preferably, above-mentioned ground wire is the GJ-80 cable.
By once unfolding two ground wires, two wire guide ropes and a middle traction rope, this technology can reduce the number of times of the flight of propeller-parachuting, increases work efficiency, energy savings, saving cost, increases security.

[embodiment]
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
Put efficient for the exhibition that improves lead effectively, the invention provides a kind of lead unfolding process, 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 Ф 3.5 high-strength caprone cables.General technology is propeller-parachuting (or dirigible) unfolding, and the manpower unfolding also can be adopted in the level land that condition is good.Before adopting propeller-parachuting (or dirigible) unfolding process, mainly adopt the manpower unfolding.
B) phase preliminary leading rope 1 unfolding secondary guide rope 2 (as shown in Figure 2) in the utilization.In the present embodiment, secondary guide rope 2 is Ф 10 enlightening Nima ropes, and phase preliminary leading rope 1 manpower unfolds secondary guide rope 2 in the utilization.In between phase preliminary leading rope 1 and the secondary guiding rope 2 the employing rotary connector be connected.
C) utilize again level guide rope 3 (as shown in Figure 3) of secondary guide rope 2 unfoldings.In the present embodiment, level guide rope 3 utilizes the secondary guide rope 3 of secondary guide rope 2 machinery unfoldings for 15 prevents turning round steel wire rope again.Secondary guide rope 2 is connected with again adopting rotary connector between grade guide rope 3.
D) utilize again traction rope 4 (as shown in Figure 4) in level guide rope 3 unfoldings.In the present embodiment, middle traction rope 4 is utilized again traction rope 4 in the level guide rope 3 machinery unfoldings for the 24 anti-steel wire ropes of turning round.The employing rotary connector is connected between level guide rope 3 and the middle traction rope 4 again
E) traction rope 4 once tracts left ground wire 5, right ground wire 6, left wire guide rope 7, right wire guide rope 8 and middle traction rope 9 (as shown in Figure 5) in the utilization.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 to open up in the phase coaster to put a guiding rope (preliminary leading rope 1, secondary guiding rope 2,3) in lead, the guiding rope (middle phase pull rope 4) of phase in utilizing then, adopt " one leads five " towing plate (to 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 and in pull rope 9) mutually disposable put logical.Divide rope at tower during the every basic iron tower of " one leads five " limp process, with 2 ground wires (ground wire 5,6) with are connected a sideline guide rope (left wire guide rope 7, right wire guide rope 8) pass behind the coaster again be connected lead five " limp connects, continue then traction, guide rope is put logical by base.The advantage of this construction technology is to reduce the number of times of the flight of propeller-parachuting, energy savings, saving cost, increase security.
Adopt the construction of above-mentioned unfolding process to have the following advantages: 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 embodiment 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 without departing from the inventive concept of the premise, 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 claims.
