Description
Technical field
The utility model relates to the high-tension electricity constructing device, especially relates to the pole rod assemblies that high-tension line is crossed over the high density ultra-high-tension power transmission line.
Background technology
Cross over 10 220kV transmission lines between 500kV Cao Jing change～south bridge variable power transmission line project 58#～61#, so the high density leap is real at home is rare, and the about 48m of 220kV transmission line height of high leap, maximum one grade of nearly 409m of crossing span, because user's importance, the 220kV transmission line of being crossed over all can not have a power failure basically.Can't have a power failure and bring very large security risk to construction, must formulate big cross over the prioritization scheme of protective equipment and lead wire and earth wire erection construction and be equipped with rational and effective do not have a power failure and cross over the construction equipment of highdensity 220kV transmission line, accelerating construction progress, improve construction efficiency, guarantee construction safety risk is eased down to minimum level.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of applied widely, application prospect is big, and has the pole rod assemblies that the high-tension line of bigger social benefit and economic benefit is crossed over the high density ultra-high-tension power transmission line.
The purpose of this utility model can be achieved through the following technical solutions: high-tension line is crossed over the pole rod assemblies of high density ultra-high-tension power transmission line, it is characterized in that, this device comprises iron tower, pole support bar body, optical cable coaster, chain block, described iron tower comprises cross-arm, described pole support bar body is arranged on the iron tower, described pole support bar body is provided with the optical cable coaster, is provided with chain block between the cross-arm of described pole support bar body and iron tower.
Described pole support bar body is arranged on the junction of main material with the oblique material of iron tower, fixes by steel wire rope.
The junction of described pole support bar body and iron tower is provided with lumps of wood pad.
Described lumps of wood pad is enclosed with sackcloth.
Compared with prior art, the utlity model has following advantage:
1, the utility model can be applicable to big span and crosses over many stringing construction protections that move extra high voltage networks to high-density, the also construction of crossing over many critical facilitys such as viaduct and marshaling yard applicable to similar big span.
2, the utility model makes leap high density high pressure and the construction of extra high voltage network stringing become simple, and establishes the theory and practice basis for routinizing of construction, and application prospect is boundless.
3, bigger social benefit and economic benefit are arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1;
Fig. 3 is an A place partial enlarged drawing among Fig. 2.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment such as Fig. 1～shown in Figure 3, high-tension line is crossed over the pole rod assemblies of high density ultra-high-tension power transmission line, and this device comprises iron tower 1, pole support bar body 2, optical cable coaster 4, chain block 3.Iron tower comprises cross-arm 5.Pole support bar body 2 is arranged on the iron tower 1, and pole support bar body 2 is provided with optical cable coaster 4, is provided with chain block 3 between the cross-arm 5 of pole support bar body 2 and iron tower 1.Pole support bar body 2 is arranged on the junction of main material with the oblique material of iron tower 1, fixes by steel wire rope.Pole support bar body 2 is provided with the lumps of wood pad that is enclosed with sackcloth with the junction of iron tower 1.
The pole support bar is a lattice pole support bar.Adopt the leap distance of lattice pole support bar can reach 300～500m, height can be according to using exhaling of iron tower to claim Gao Laiding.Lattice pole support bar adopts the pole stage casing of segment length 600 * 600 * 4000mm to be formed by connecting; length respectively adds 3m by the protection range both sides of being crossed over thing and decides, and generally is installed in iron tower and crosses on the body of the tower that phase conductor downside hanging wire point is located about about 6～8m down under the side.Every section of pole support bar is installed to be connected with the M12 bolt and tightens.The pole support bar is fixed on the junction of body of the tower master material and oblique material, pole support bar and body of the tower junction use φ 15.5mm steel wire rope to fix, and all need to use lumps of wood pad with pole support bar junction, the parcel sackcloth, with steel wire rope very heavy around, can not directly tie up on the tower material.Each is with the very heavy extension of a φ 12.5mm steel wire rope 2t coaster under the cross-arm of both sides, lift by crane the pole support bar with φ 12.5mm steel wire rope at two ends by body of the tower and tower leg corner block, pole support bar two ends are dragged root to be controlled at φ 16mm coir rope and are not bumped body of the tower in the lifting process.The two ends of pole support bar overhanging arm add to tie up together with the 3t chain block with two φ 12.5mm steel wire ropes very heavy " V " type and are anchored on the cross-arm rear side master material with each, and the two limit cross-arms cross-arm that makes progress respectively adds and makes a call to φ 12.5mm steel wire rope very heavy adding together with the 3t chain block and tie up anchoring.When being fixed on the pole support bar on the iron tower, also will consider pre-deviator, the inboard adds insurance, prevent the extreme case lead waft from.
