Abstract

A method of installing signalization spheres on energized transmission lines. A supporting structure, consisting of two bases equidistant, parallel to each other, linked to each other by axial segments, the axial segments acting as supports for activation engines, respectively, a grounding and idler tension system including a structure formed by two parallel rods that move along the vertical direction linked to two bases equidistant and parallel to each other in its intermediate portion through an axis. In its superior extremity through an axis and presenting in its inferior extremity slots for the introduction of an axis of a wheel. A first axial segment being equipped in its intermediate portion with a threaded rod which is linked it its inferior extremity to the axial segment of the bases superiorly equipped with a crank and spring. A fork is articulated over a pivot to the external part of the bases whereto are projected the feeding system. An inclined structure consisting of two bases equidistant to each other is linked to each other by four axial segments. The latter acting as a support for the tightening and loosening tool presents in its terminal portion a coupling prism suspended internally and externally by bars respectively and equidistant to each other by the axial segments.

Claims

1. Method for installation of signalization spheres on energized transmission lines, comprising the following steps:

placing a signalization sphere through a lateral spacing existing between two semi-spheres on a lightning rod cable until the lightning rod cable is accommodated by a walrus-type connector as, the signalization sphere is made available to be transported without risk of falling along said lighting rod cable;

placing an installation device upstream, in relation to the signalization sphere, by placing the device over the lightning rod cable, which is in contact with two activation engines of the installation device, by placing a wheel in a slot through an axis groove so that, in this way, the grounding of the device is effected, as the wheel is constituted by metallic conductive material and all the other components of the device are made of an insulating material;

coupling of an extremity of a coupling prism to a horizontal axis of the sphere in an extremity of an eyelet to the installation device;

activating the device by a remote-control transmitter by the engines; and

rotating in a tightening direction, through remote control, a tightening and loosening tool, which rotation affects the eyelet of the extremity at a vertical axis, providing closure of the walrus-type connector over the lightning rod cable.

2. The method, according to claim 1, further comprising a grounding and idler tension array of the device assembled with a feeding system assembled in a pivot (46), acts as a pendulum, being responsible for balance of the array.

3. The method, according to claim 1, wherein a voltage of a feeding system is transferred towards the activation motors as well as to the tightening and loosening tool by parallel wires.
