Four-pipe tower of power transmission line

Abstract

The invention discloses a four-pipe tower of a power transmission line, belonging to four-pipe towers. The four-pipe tower structurally comprises a tower body and a tower leg, wherein a ground wire bracket, an upper wire cross arm, a middle wire cross arm and a lower wire cross arm are sequentially arranged on the tower body; the middle wire cross arm is slightly longer than the upper wire cross arm and the lower wire cross arm; the tower body comprises tower columns, a diagonal rod and a cross rod; the cross section of the tower body is quadrilateral, wherein four tower columns are respectively arranged at corners of the quadrangle, the tower columns are made of steel pipes, and a connecting plate is welded on the circumferential surface of each tower column; the cross rod and the diagonal rod are in bolted connection with the tower columns through a connecting plate; the tower body is formed by connecting a plurality of sections of gradient-change tower sections; and flange plates are respectively welded at two ends of each section of tower section, and the tower sections are fixed through the flange plates. Compared with the prior art, the four-pipe tower of the power transmission line, disclosed by the invention, has the characteristics of rich and attractive shapes of the tower body, convenience for transportation and installation, good windproof effect, good rigidity, inexistence of potential safety hazards, and the like, thereby having favorable popularization and application values.

Description

technical field [0001] The invention relates to an iron tower, in particular to a four-pipe tower for transmission lines. Background technique [0002] With the rapid development of my country's electric power industry, angle steel towers for transmission lines have been widely used, but the triangular steel towers currently used still have the following shortcomings: due to the use of an integral tower structure with equal slopes, the shape is single and rigid , In addition, the overall size is large, it cannot be disassembled, it is inconvenient to transport and install, the windproof effect is poor, the rigidity is poor, and there are potential safety hazards. Currently, there is no good solution. Contents of the invention [0003] The technical task of the present invention is to provide a four-pipe tower for transmission lines in view of the deficiencies in the prior art above. characteristics of safety hazards. [0004] The technical solution adopted by the present...
