Problems solved by technology
[0002] At present, the steel pipe poles of multi-circuit transmission lines with large loads on the ground wires are mainly divided into double-pole structures and four-pole structures. The diameter and wall thickness of the lower part of the main rod are designed to be larger, which will lead to problems such as difficult processing, inability to galvanize, and difficulty in transportation
[0003] In order to solve the problems of steel pipe poles with double pole structure, generally design units will use steel pipe poles with four pole structures, but steel pipe poles with four pole structures need to consume more steel, resulting in higher production costs, and installation and construction are more difficult than double poles. Steel tube poles for pole construction have been increased

Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0015] Such as Figures 1 to 3 As shown, a steel pipe pole of a power transmission line includes a main pole body 100 and several crossarms 200, and the crossarms 200 are installed on the main pole body 100. The two rod bodies of the rod body 110 and the rod bodies of the four-rod body 130 are all connected by connecting beams 140. Both the double-rod body 110 and the four-rod body 130 are segmented structures, and each section of the two rod bodies is connected by a flange. connect. The connecting joint 120 is connected into a "herringbone" shape by an upper connecting pipe 121, a horizontal connecting plate 122 and two lower connecting pipes 123. The two connecting joints 120 are connected into one body through a connecting beam 140. The double rod body 110 corresponds to the two connecting joints 120. The upper connecting pipe 121 is connected, and the four-bar ...

The invention discloses a steel pipe rod of a power transmission line, and relates to power transmission equipment. The steel pipe rod comprises a main rod body and a plurality of cross arms, and thecross arms are installed on the main rod body; the steel pipe rod is characterized in that the main rod body comprises a two-rod body, a four-rod body and two connection joints, each connection jointis connected with an upper connection pipe, a horizontal connection plate and two lower connection pipes to form a herringbone shape, and the two connection joints are integrally connected through a connection cross beam; the two-rod body is correspondingly connected with the upper connection pipes of the two connection joints, the four-rod body is correspondingly connected with the lower connection pipes of the two connection joints, two rods of the two-rod body are connected through a connection cross beam, all rods of the four-rod body are connected through connection cross beams, the two-rod body and the four-rod body are both of a segmented structure, and all segments of the rods of the two-rod body and the four-rod body are connected through flanges. The steel pipe rod is high in bearing capability, low in production cost and convenient to install and construct.
