Problems solved by technology

[0003] The purpose of the present invention is to overcome the difficulty of ensuring the natural growth height of buildings and plants under the existing conventional towers with reduced appellation height, and secondly, it is difficult to meet the safety distance of wire crossing even if the appellation height is lowered in some extreme crossing stalls. To solve the problem, provide a power transmission line drilling tower to ensure that the height from the ground is increased while avoiding the upper transmission line

Abstract

The invention discloses a power transmission line drilling tower, which includes a tower body fixed on the working surface and a compensation mechanism for compensating the offset of the tower body. The tower body includes a tower foot assembly and a truss erected on the tower foot assembly , the truss is placed horizontally, and the lower end surface of the truss is provided with a plurality of terminals for fixing the transmission lines.

Description

technical field [0001] The invention relates to a power transmission tower, in particular to a power transmission line drilling tower. Background technique [0002] At this stage, with the development of cities, the transmission line channels are becoming more and more tense. During the design and infrastructure construction of new lines, it is difficult to avoid crossover situations. In reality, there are a large number of 110kV-220kV drill-through 500kV and other high-voltage lines. Most of the previous design schemes used conventional tower types, but only reduced the height of the tower type. For example, a kind of "a single-circuit iron tower that simultaneously solves the needs of drilling and crossing" disclosed in the Chinese patent literature, its announcement number is CN109469399A, the tower body is respectively equipped with a ground wire cross arm, a second floor cross arm Bearing and the third layer of cross arms, an outwardly protruding upper mid-phase susp...
