(54) УГЛОВАЯ ОПОРА ЛИНИИ ЭЛЕКТРОПЕРЕДАЧИ(54) ELECTRICAL TRANSMISSION ANGULAR SUPPORT

1one

Изобретение относитс к строитепьстщг , а именно к опорам дл пиний эпектропередачи высокого напр жени .The invention relates to construction, namely, to supports for high voltage transmission lines.

Известна углова опора линии электропередачи , включающа стойку, верхнюю и нижнюю траверсы и отт жки 1),The known angular support of the power line, including the stand, the upper and lower traverses and braces 1),

Недостатком вл етс наличие системы отт жек, занимающей большую ппошадь .The disadvantage is the availability of an overload system that takes up a lot of space.

Наиболее близкой по технической сущ- ,и ности к предлагаемой вл етс углова опора пинии электропередачи, включающа стойку, соединенные горизонтальными св з ми , траверсы и отт жки, прикрепленные к верхним концам стоек 2,,5The closest in technical essence to the proposed is the angular support of the power transmission line, comprising a rack, connected by horizontal ties, traverses and straps attached to the upper ends of the uprights 2, 5

Недостатком опоры вл етс сложность монтажа и нерациональность ее элементов при установке на слабых грунтах и при больших углах поворота линии,The lack of support is the complexity of installation and the inefficiency of its elements when installed on weak soils and at large angles of rotation of the line,

Цель изобретени - упрощение монтажа и улучшение условий эксплуатации опоры при установке на слабых грунтах или при больших углах поворота.The purpose of the invention is to simplify installation and improve the operating conditions of the support when installed on weak soils or at large angles of rotation.

Поставленна цель достигаетс тем, что в угповой опоре линии . электропередачи , включающей стойки, соединенные горизонтальными св з ми, траверсы и отт жки, прикрепленные к верхним концам стоек, кажда стойка снабжена балкой , шарнирно прикрепленной одним концом к нижней части стойки со стороны вершины угла поворота, и пригрузочными элементами, причем балки выполнены с грузовыми площадками на свободных концах , на которых установлены пригрузочные элементы, а отт жки нижними концами прикреплены к свободным концам балок.The goal is achieved by the fact that in the Ugp line support. power transmission, including racks connected by horizontal ties, traverses and straps attached to the upper ends of the racks, each rack is equipped with a beam hinged at one end to the lower part of the rack from the top of the angle of rotation, and loading elements, and the beams are made with cargo the platforms at the free ends, on which the load-bearing elements are installed, and the ends of the lower ends are attached to the free ends of the beams.

На фиг. 1 изображена опора, общий вид; на фиг. 2 - то же, в плане.FIG. 1 shows the support, general view; in fig. 2 - the same in terms of.

Опора линии электропередачи высокого напр жени включает две стойки 1, установленные в сверление котлованы 2. The high-voltage power line pole includes two pillars 1, installed in the drilling pit 2.

Claims

20 Beams 3, hingedly attached to the top of the angle of rotation of the line, are hinged to the lower parts of each of the uprights. The free ends of the beams 3 96 are connected by flexible ties 4 to the upper part of the uprights 1 and are equipped with cargo platforms 5, on which the standard loading elements 6 are mounted. The tipping moment transmitted to the base of the uprights 1 installed in the drilled excavation 2 is greater, angle of rotation pines. At significant turning angles or on weak soils, the carrying capacity of fixing the pillars in drilled trenches is not enough to accommodate tilting moments. Tight elements 6 create a moment opposing the tilting moment and are determined by the weight and number of elements 6 as well as the length of the beam 3. In this case, the bearing capacity of embedding the stand base and its strength are fully used, since the number of loading elements 6 is optimally assigned in such a way as to compensate for the moment transmitted to the rack. In the process of mounting, the support is placed only a part of the loading elements, taking into account reduced tilting moments during installation, and the remaining loading elements 6 are placed at the end of installation and fixed on cargo platforms 5. Thus, in the design, the amount of cargo is minimally necessary, the strength of the rack and its fixtures are fully utilized, which provides savings in capital investments and labor costs for the construction of the support, allows the use of two-column free-standing supports as anchor angle and large angles of rotation of the line, as well as in the case of their installation in weak soils. The formula was invented, and Uglov from the Jurassic transmission line, including racks, connected by horizontal links, traverses and wires, attached to the upper ends of the racks, in order to simplify installation and improve the conditions of operation of the support when installed on weak soils or at large angles of rotation, each rack is equipped with a beam, hinged at one end to the bottom of the rack from the top of the angle of rotation, and load-bearing elements, and the beams are made with load areas on a free end tsakh, on which the load-bearing elements are installed, and the ends of the lower ends are attached to the free ends of the beams.
