Electric overhead line laying traction machine and construction method

Abstract

The invention relates to an electric overhead line laying traction machine and a construction method. The electric overhead line laying traction machine comprises a lifting cross rod, clamping devices, fixed traction devices and a driving device, the clamping devices are symmetrically arranged at the left end and the right end of the lifting cross rod, the fixed traction devices are connected to the upper portion of the middle of the lifting cross rod, and the driving device is arranged in front of the lifting cross rod. According to the invention, when the overhead line is installed, usually,a worker needs to hold the free end of a single overhead line by hand to climb the upper end of a telegraph pole to install and tighten the line. A plurality of overhead lines need to be placed on asingle telegraph pole, so that the worker needs to climb to the upper end of the telegraph pole for multiple times, potential safety hazards of the personnel are easily caused in the climbing processfor multiple times due to the fact that the overhead lines are heavy, meanwhile, the pole body of the telegraph pole is likely to incline due to climbing for multiple times, and the paying-off efficiency of the single telegraph pole is low.

Description

technical field [0001] The invention relates to the field of electric power construction tools, in particular to a traction machine for laying electric overhead lines and a construction method. Background technique [0002] Existing overhead lines are generally fixed on utility poles by street codes. When using street codes to fix overhead wires, it is necessary to pull the overhead wires from the pay-off reel to the pole, and then the construction workers put the overhead wires on the street codes on the poles to complete the wire release operation. In order to reduce corona In order to avoid loss and corona interference, phase split wires are used, that is, two or more wires are used for each phase to erect, so there are multiple overhead wires placed on one cross arm. [0003] When installing overhead lines, it is usually necessary for staff to hold the free end of a single overhead line and climb the upper end of the utility pole to install and tighten the line. Since m...

Problems solved by technology

[0005] The present invention can solve the problem that when installing overhead wires, it is usually necessary for workers to hold the free end of a single overhead wire and climb the upper end of the utility pole to install and tighten the wires. It is necessary to climb to the upper end of the utility pole multiple times. Due to the heavy weight of the overhead line, it is easy to cause safety hazards during the multiple climbing process. At the same time, the utility pole may be tilted due to multiple climbing. Problems such as low pay-out efficiency of utility poles
