Description
Technical field
The application belongs to transmission line equipment field, novel steel tube---the angle steel mixing tower of especially a kind of transmission line of electricity use.
Background technology
Along with the construction of China's extra-high voltage grid and the universal of transmission line of electricity multiple-loop line technology, steel tower is more obvious to the trend of large load and development of maximizing, and the superiority that steel tube tower is applied more and more causes the concern of people.Compared with angle steel tower, steel tube tower component windage effect is little, rigidity of section is large, iron tower construction member is few, power transmission is clear, structure is reliable, be conducive to strengthening the ability of structure opposing natural calamity under extreme condition, and can saving steel and base concrete, there is good Social benefit and economic benefit.
Electricity east, Anhui send (Huainan-Shanghai) project of transmitting and converting electricity (being called for short: extra-high voltage East Route Project) to be China Article 1 1000kV multiple-circuit on same tower, adopts steel tube tower structural shape completely, as shown in Figure 2.According to the research work in early stage, substantially determine that the ripe production capacity of domestic steel tube tower only has 160,000 tons/year, there is larger breach contradiction with the amount of engineering all fronts 25-30 ten thousand tons.State Grid Corporation of China is from many-sided expansion in-depth such as scientific research, design, production research, especially standardized designs and the measure such as optimization and processing technology of steel tube tower is strengthened, production work efficiency is farthest improved under the prerequisite guaranteeing quality, achieve great successes and significant benefit, but the production pressure of East Route Project steel tube tower is still very large.Consider the application of steel tube tower in other electric pressure transmission lines of electricity again, what the production capacity of steel tube tower deficiency had become that it promotes on a large scale seriously keeps in check.
Summary of the invention
The object of the present invention is to provide the novel steel tube that a kind of transmission line of electricity uses---angle steel mixing tower, when keeping steel tube tower structural advantages, suitably improves the ratio of angle steel material in steel tower, to alleviate the problem of steel tube tower production capacity deficiency in engineering.
A kind of steel pipe and angle iron hybrid ultrahigh-voltage power transmission tower, this electric power pylon turriform is double loop tangent tower, comprises the tower head, tower body 6 and the tower leg 7 that connect successively; It is characterized in that:
Tower head is made up of earth wire support 1, upper cross-arm 2, middle cross-arm 3, lower cross-arm 4 and tower body center pillar 5, described upper cross-arm 2, middle cross-arm 3, lower cross-arm 4 arrange from top to bottom, all arrange perpendicular to tower body center pillar 5, and with tower body center pillar 5 for axisymmetrical, described earth wire support 1 is arranged on the both side ends of cross-arm 2;
Tower head is connected by steel pipe angle steel transition node 8 with tower body 6;
Described tower head part all adopts angle iron component to make;
Tower body 6 and tower leg 7 adopt steel tube component to make.
Further, described transition node 8 is arranged in the internode of more than the main material of lower cross-arm 4 lower plane and the main material intersection point of tower body center pillar 5, adopts column foot template formula, is made up of base plate, boots plate and stiffener.
The application has following technique effect:
Under steel tower, cross-arm above tower head position (comprising earth wire support 1, upper cross-arm 2, middle cross-arm 3, lower cross-arm 4 and tower body center pillar 5) all adopts angle iron component, and joint structure is simple, easy to connect; Tower body 6 and tower leg 7 all adopt steel tube component, simple for structure, power transmission is clear, can give full play to the load-carrying properties of material, effectively reduce steel tower weight.Compared with conventional steel tube tower, novel mixing tower, when keeping steel tube tower structural advantages, significantly improves the ratio of angle steel material, effectively can alleviate the problem of steel pipe production capacity wretched insufficiency in current China work transmission line.
