Background technology
At present, China's transmission line of electricity mainly adopts single loop and Double Loop Steel Tower, along with economic development, society is increasing to the demand of powerful electrical network, and the process of urbanization makes the resource in power overhead network corridor fewer and feweri, for power grid construction is synchronizeed with urban development, the harmonious social environment of building together, need to improve the transmission capacity of circuit unit corridor, improve land utilization ratio.
Along with the fast development of China's economic construction, " with severe power shortage " phenomenon is day by day serious.For electric power production capacity between balanced zones of different, more and more with tower multiloop, UHV transmission line, start to build, three loop tangent towers have the larger meaning that realizes.But these circuits have the advantages that conductor load is large, the load on the steel tower of answering is in contrast also very large, if according to traditional habit, continues to use Q345 steel, generally will use combination angle steel (Two bors d's oeuveres angle steel or four is spelled angle steel) or steel pipe.Combination angle steel has increased tower weight greatly, and processing capacity is very large, and steel tube tower processed complex, welding capacity are large, are not easy to mountain area transportation.
Utility model content
The technical problem that the utility model mainly solves is to provide three loop tangent towers of a kind of high strength heavy in section angle steel, the first loop, second servo loop and tertiary circuit adopt the large specification angle steel of Q420, use the high-intensity heavy in section of Q420 angle steel, can avoid to a certain extent using combination angle steel, reduce at double the processing capacity of steel tower, a large amount of connecting bolt and fill plates of reducing, reduce steel tower steel consumption, also make construction volume and the difficulty of construction of tower erection greatly reduce, and more reasonable structure, steel tower is safer.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the three loop tangent towers that a kind of high strength heavy in section angle steel is provided, comprise tower head and tower body, on described tower body, be provided with the first loop, second servo loop and tertiary circuit, the first described loop, second servo loop and vertical arrangement of tertiary circuit are on the top of tower body.
In preferred embodiment of the utility model, the first described loop, second servo loop and tertiary circuit adopt the large specification angle steel of Q420.
In preferred embodiment of the utility model, it is characterized in that, described the first loop, second servo loop and tertiary circuit are double triangle structure.
In preferred embodiment of the utility model, described tower head is triangular structure, is separately positioned on the left and right sides on tower body top.
In preferred embodiment of the utility model, the width of described the first loop, second servo loop and tertiary circuit equates.
The beneficial effects of the utility model are: three loop tangent towers of high strength of the present utility model heavy in section angle steel, the first loop, second servo loop and tertiary circuit adopt the large specification angle steel of Q420, use the high-intensity heavy in section of Q420 angle steel, can avoid to a certain extent using combination angle steel, reduce at double the processing capacity of steel tower, reduce in a large number connecting bolt and fill plate, reduce steel tower steel consumption, also make construction volume and the difficulty of construction of tower erection greatly reduce, and more reasonable structure, steel tower is safer.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:
Fig. 1 is the structural representation of three loop tangent tower one preferred embodiments of high strength of the present utility model heavy in section angle steel;
In accompanying drawing, the mark of each parts is as follows: 1, tower head, 2, tower body, 3, the first loop, 4, second servo loop, 5, tertiary circuit.
The specific embodiment
Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
Three loop tangent towers of a kind of high strength heavy in section angle steel, comprise tower head 1 and tower body 2, on described tower body 2, be provided with the first loop 3, second servo loop 4 and tertiary circuit 5, the first described loop 3, second servo loop 4 and 5 vertical arrangements of tertiary circuit are on the top of tower body 2, and the first described loop 3, second servo loop 4 and tertiary circuit 5 adopt the large specification angle steel of Q420.Wherein, described tower head 1 is triangular structure, is separately positioned on the left and right sides on tower body 2 tops.
In above-mentioned, the first loop 3, second servo loop 4 and the equal vertical arrangement of tertiary circuit 5, whole tower is door frame type and arranges.Wherein, described the first loop 3, second servo loop 4 and tertiary circuit 5 is double triangle structure; The width of described the first loop 3, second servo loop 4 and tertiary circuit 5 equates.
Further, the conveying voltage capacity of three loop tangent towers is 220-500kV, and the load of steel tower is larger, adopt the large specification angle steel of Q420, can reduce the 5%-10% of tower material index, reduce the welding capacity in Tower processing process, improve working (machining) efficiency, there is the advantage of saving Energy Intensity Reduction toxic emission.
In the present invention, the first described loop 3, second servo loop 4 and tertiary circuit 5 adopt the large specification angle steel of Q420, adopt the large specification angle steel of Q420 can simplify iron tower structure, a large amount of connecting bolt and fill plates of reducing, fall lower steel consumption index, alleviate steel tower production work amount, reduction group tower difficulty of construction, and more reasonable structure, steel tower is safer.Through actual comparative analysis, brocade Soviet Union's engineering pilot application large-size high-tensile angle steel, even open remain unchanged with stone bolt in the situation that at former design steel tower root, single base steel tower at most still can loss of weight 3%, 60,000 yuan of comprehensive cost reductions, technology economy advantage is obvious.The research of large-size high-tensile angle steel tower and application are the Important Actions of electrical network capital construction field energy-saving and emission-reduction, meet the requirement that power network development mode changes, and will have wide practical use in feeding back electrical engineering in extra-high voltage with tower more.
Three loop tangent towers of the high strength heavy in section angle steel that the utility model discloses, the first loop 3, second servo loop 4 and tertiary circuit 5 adopt the large specification angle steel of Q420, use the high-intensity heavy in section of Q420 angle steel, can avoid to a certain extent using combination angle steel, reduce at double the processing capacity of steel tower, reduce in a large number connecting bolt and fill plate, reduce steel tower steel consumption, also make construction volume and the difficulty of construction of tower erection greatly reduce, and more reasonable structure, steel tower is safer.
