Abstract
The invention relates to a tension stringing construction process with an odd number of conductors, which opens up a new way for the spreading of an odd number of multi-split large-section conductors for the ultrahigh voltage engineering. The tension stringing construction process comprises the following steps of: improving a one-drag-four payoff tackle at a lowest cost to realize the matching and the common use of one-drag-four and one-drag-three tackles; selecting the type for a one-drag-three running board, ensuring that the self torque of the one-drag-three running board is balanced, and the one-drag-three running board is matched with the tackles and has strong passing performance and small extrusion for the tackles; researching and developing a novel one-drag-three payoff matched tool and forming the whole set of novel 2* one-drag-three tension stringing construction process.
Description
Technical field
This
InventionRelate to odd number wire tension overhead construction process.
Background technology
Increasingly high along with electric pressure, transmission capacity is increasing, more large-section lead constantly occurs, and has further improved laying tension, adopts even number lead traction again, main pull rope needs all upgradings to order again; As adopt the traction of odd number lead, releasing pulley need change to even number wheel eccentric wheel, and not strong with existing unwrapping wire mode matching, drop into huge.Research is transformed existing " one leads four " releasing pulley with the cost of minimum; Realize " one leads four " and " one leads three " mode coaster coupling, general; Form novel " 2 * one lead three " construction under tension stringing technology, for ± 800kV brocade Soviet Union line stringing reaches later large-section lead odd level unfolding conductor has extremely important meaning.
" one leads three " tension stringing is domestic to have Beijing to send power transformation to use in the lineman's journey that makes progress; Beijing send that power transformation adopts is six to take turns eccentric wheel, and this type coaster has been owing to adopted eccentric structure, can realize three root leads, main lead through the time all be in poised state; Because this type coaster needs customization again; Equipment has high input, and not strong with existing Work tool versatility, application value is not high.
Novel " 2 * one lead three " construction under tension stringing technology; Transform the hang of existing five wheel line tackles; Realized the slitless connection of from " one leads four " to " one leads three " unwrapping wire mode with the cost of minimum; Very strong promotional value is arranged, this " one leads three " overhead construction process, five wheel line tackle highly versatiles, do not need the customization.Novel " 2 * one lead three " construction under tension stringing technology overhead construction process does not still have relevant unit at home and in engineering, uses.
Summary of the invention
Be used for novel " 2 * one lead three " construction under tension stringing technology, it is characterized in that: adopt cost transformation " leads four " Φ 916mm five to take turns the sipes releasing pulley, realize " one leads four " and " one leads three " mode coaster coupling, general with minimum; Develop the supporting Work tool of novel " one leads three " five wheel line tackles; Select " one leads three " limp with five wheel line tackles coupling; Study novel 2*1 and lead 3 tension stringing coaster hangs.
Concrete technical solution is following:
Said five wheel line tackles adopt the double hanging point design, and single-point intensity satisfies force request, and two dot structures are used for self-balancing.
Said novel 2*1 leads 3 construction under tension stringing process matching Work tools and comprises special connection channel-section steel, the parallel link plate of P-2522, GJ-150 steel strand wire.
Said special connection channel-section steel middle part is provided with φ 39 holes, two φ 26 holes, is used to connect the tangent tower LXV yoke plate construction hole of dangling.
Two φ 32 holes that increase on parallel link plate of said P-2522 and the coaster yoke plate match, and promptly each five is taken turns coaster and adopt two parallel link plates of P-2522 to link to each other with the special channel-section steel that is connected, and is used for self-balancing.
Said GJ-150 steel strand wire are that gold utensil is supplied under the untimely situation, replace the gold utensil string and the hanger of special processing, its two ends compressed steel anchor.Be different from and traditional hanger (like pull-rod), its have in light weight, can stretch in the wrong, be easy to characteristics such as installation, convenient transportation.
Said " one leads three " limp adopts the asymmetrical design principle to guarantee self-balancing, and structure and coaster are supporting.Two parts before and after limp is divided into connect through the bolted splice formula, are beneficial to through coaster, and job-hopping is avoided in applying more, steady.
Said coaster hang is: link to each other through special connection channel-section steel construction hole, middle part (6,7) and LXV yoke plate (4) hole of constructing of dangling; Gold utensil does not utilize GJ-150 steel strand wire (5) to replace the gold utensil string to link to each other with the special construction holes, channel-section steel both ends (10) that are connected under situation; Then through go up two φ 32 holes (9) that increase at coaster yoke plate (8); Connect with the special channel-section steel that is connected with two parallel link plates of P-2522 (3), guaranteed main when leading with lead through coaster coaster all be in poised state.This
InventionUseful technique effect be embodied in following several aspect:
1, makes full use of existing unwrapping wire facility completion six division large-section leads exhibitions and put, avoid purchasing jumboes such as large-tonnage hauling machine, pull rope, releasing pulley, reduce the equipment purchasing cost.
2, on details, optimize, the coaster double hanging point improves balance quality; The oblique guide rail simplified structure of limp, the balance when three root leads are drawn in the raising limp.
3, the exhibition of lead and pull rope minute wheel is put, and avoids the lead wearing and tearing; The sub-conductor spacing strengthens, and reduces sub-wire flogging and twisted wire probability, is beneficial to wire-protecting; Convenient follow-up construction technology is installed.
