Abstract
A novel guide rope laying one-pull-seven construction method relates to a guide rope laying method. At present, the guide rope laying mainly has the disadvantages that back-and-forth traction laying process is tedious; a plurality of high-altitude rope moving is needed in the whole process and the high-altitude construction amount is large; and the process is tedious and is time consuming. The novel guide rope laying one-pull-seven construction method comprises the following step: 1) pulling and laying ropes: a powered parachute aerially lays a [phi]2 Deenyma rope serving as a primary guide rope for construction, and the Deenyma ropes are dragged and laid manually in the order of [phi]2 Deenyma rope-[phi]4 Deenyma rope-[phi]8 Deenyma rope; the ropes are in tension laying in the order of [phi]8 Deenyma rope-[phi] 15 anti-twisting steel wire rope-[phi]25 steel wire rope; during tension laying, a large tractor and two large tension machines are utilized to carry out guide rope one-pull-seven tension laying, wherein one large tension machine lays three ropes and the other large tension machine lays four ropes; and 2) moving plate passing through a pulley and rope branching. With the technical scheme, the labour intensity is low and the construction efficiency is high.
Description
Technical field
The present invention relates to a kind of messenger unfolding method.
Background technology
Along with social progress, the development of power grid construction, also there is variation with rapid changepl. never-ending changes and improvements in transmission line construction.Lead wire and earth wire erection construction, from original artificial unfolding, develops into tension stringing gradually; From artificial spreading guiding rope to passing through the high technology equipment unfolding preliminary Di Nima messengers such as propeller-parachuting, remote control airship, RC Goblin, helicopter, speedboat, new equipment, new technology, a large amount of introducing of new material, for the high new development of transmission line construction is laid a good foundation.
The densely covered region in project of transmitting and converting electricity work transmission line construction passage or the network of waterways or no man's land, high mountain high hill, have inconvenient traffic, and affected by the factor such as landform, traffic larger.If adopt conventional artificial pilot rope laying mode, there is certain difficulty in pull rope unfolding, brings certain difficulty also to the processing of engineering policy simultaneously.For fully reducing the impact of passage in circuit stringing construction, accelerate payingoff speed, current most Poling Constructions all adopt the construction method of the flight equipment pilot rope layings such as propeller-parachuting, make messenger unfolding overall process face sky.
Conventional spreading lead wire and earth wire construction process is as Fig. 2, in construction, guide rope unfolds main existent defect and is: it is loaded down with trivial details that (1) tracts operation back and forth, need to be from original φ 2 enlightening Nima → φ 4 enlightening Nima → φ 8 enlightening Nima → 9 steel wire ropes (or 2 φ 8 enlightening Nimas, rope is moved in high-altitude again) → 15( 13) steel wire rope → 18 steel wire ropes (or 49 steel wire ropes, then rope is moved in high-altitude) → 25( 28) steel wire rope → mono-leads four wires; (2) in whole process, need repeatedly high-altitude to move rope, amount of high-altitude operation is very large; (3) double door releasing pulley quantity required is many; (4) operation is loaded down with trivial details, elapsed time.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is that prior art scheme is improved and improved, and provides new-type messenger unfolding one to lead seven construction methods, to reach the object that improves Poling Construction efficiency.For this reason, the present invention takes following technical scheme.
New-type messenger unfolding one is led seven construction methods, it is characterized in that it comprises the following steps:
1) rope is put in traction
A. propeller-parachuting unfolds φ 2 enlightening Nima ropes in the air as working elementary messenger, and by the order of Φ 2 enlightening Nima rope → Φ 4 enlightening Nima rope → Φ 8 enlightening Nima ropes, manpower traction unfolds Di Nima rope;
B. by the anti-steel wire rope → 25 steel wire rope order showing and placing of the tension of turning round of Ф 8 enlightening Nima rope → 15; When showing and placing of the tension, utilize a large traction machine and two hightension machines to carry out leading seven showing and placing of the tension guide ropes, wherein a hightension machine unfolds 3,4 of another hightension machine unfoldings, totally 7 15 steel wire ropes;
2) coaster and point rope are crossed in limp
A. lead slowly 7 15 guide ropes of traction of seven limps by one, the releasing pulley of 7 corresponding shaft tower one sides of 15 guide ropes is respectively: be arranged in first coaster failing to agree, be positioned at second coaster failing to agree, the 3rd coaster failing to agree under being positioned at, be positioned at the 4th coaster for ground wire unfolding at top, be positioned at the 5th right mutually coaster, be positioned at lower the 6th coaster on the right side mutually, be arranged in the 7th right mutually coaster, first, second, the 3rd, the 4th, the 5th, the 6th, the 7th 7 15 guide ropes corresponding to coaster are respectively first, second, the 3rd, the 4th, the 5th, the 6th, No. seven rope,
B. when limp at a slow speed by middle phase guide rope behind the corresponding about 60-70m of coaster position large traction machine stop, hightension mechanism is moving, controls second, third, the bending resistance of the 4th, the 5th, No. six rope or rotary connector be near near coaster;
C. utilize in advance colligation is good on cross-arm node separately 5 anchoring ropes by second, third, the 4th, the 5th, No. six rope all face anchor; Face anchor line and adopt Ф 13 steel wire covers, length is 20-30m;
D. after facing anchor line and arranging, large traction machine slack rope at a slow speed, first, No. seven rope be according to guide rope sag situation on circuit, operation tensioner slowly reclaims; Note observing coaster place second, No. six rope, avoid second, the 6th rope and first, No. seven rope friction, collision or be wound around;
E. after all anchoring ropes are stressed, stop hauling machine and tensioner, check confirm to face anchor system effectively stressed after, slack rope and first, No. seven rope slowly reclaim at a slow speed to continue operation large traction machine;
F. until limp to approaching after coaster, stop hauling machine and tensioner braking, by second, third, the 4th, the 5th, the 6th, No. seven rope carry after pine, remove successively the rotary connector being connected with limp, then climb over respectively separately and be again connected with limp again after coaster, connect after intact and open tensioner brake, slowly operate large traction machine and draw;
G. anchor line to be faced and 15 guide rope junctions are walked near coaster, suspend traction, by hauling machine and tensioner braking, remove and face anchor system, then continue traction, complete a side messenger unfolding job of a base double.
As the further of technique scheme improved and supplemented, the present invention also comprises following additional technical feature.
Limp comprises trapezoidal body, be located at first rotary connector of body head, be located at seven the second rotary connectors of body bottom, wears 25 steel wire ropes in the first rotary connector; In the second described rotary connector, wear 15 steel wire ropes, seven the second rotary connectors divide two rows to be arranged on the tail end of limp.
