Problems solved by technology

[0002] In the process of erecting overhead transmission lines, how to realize the traction and installation of conductors across complex areas such as rivers and mountains is one of the thorny problems encountered by construction personnel. Due to the above-mentioned harsh working environment and difficult construction, special hoisting equipment is generally required This brings problems of procurement (or leasing), transportation and on-site installation of special equipment, which not only increases the construction cost, but also prolongs the construction period

Abstract

The invention discloses equipment and a method for installing wires of an overhead power transmission line, and belongs to the technical field of cable or electric wire installation. The equipment for installing the wires of the overhead power transmission line comprises an aircraft, a steel wire rope, pulley assemblies, a take-up and payoff device and a wire installation device, wherein the pulley assemblies are installed on a first electric pole and a second electric pole at two ends of a construction area section; the steel wire rope is dragged by the aircraft to bypass the pulley assemblies, and the two ends of the steel wire rope are used for controlling the tensioning force through the take-up and payoff device; and the wire installation device walks along the steel wire rope so as to drag the wires to span the overhead of the complicated construction area section. According to the equipment for installing the wires of the overhead power transmission line disclosed by the invention, the installation of the wires of the overhead power transmission line spanning the complicated area sections such as rivers and mountains is realized, the construction cost is reduced, the work efficiency is improved, the construction period is shortened, and the damages for the wires in the installation process are avoided.

Description

technical field [0001] The invention relates to a wire installation device and method, in particular to a wire installation device and method suitable for overhead transmission line wires crossing complex areas such as rivers and mountains, and belongs to the technical field of cable or wire installation.
