System for the installation of the sphere of air signalling in distribution networks and transmission lines of high voltage and extra high voltage, from the ground by rope

摘要

"System for the installation of the air signalling in distribution networks and transmission lines of high voltage and extra high voltage, from the ground by rope.It is presented a new device for opening / closing of the spheres that allows its installation in the cables, as well as withdrawal, from the ground.Avoiding the use of helicopters, or the need for displacement of the operator through cables. The sphere has a lug type (2) and a trigger (3) with the bolt (4).A first operator, working on the floor, open the sphere with the aid of a special pliers (Fig. 6), arming the device opening / closing and locking it open by means of the trigger (3).A rope is tied on the lug (4) of the trigger (3) and in the splicing of drag (2) using a node type that allows us to drop the rope, after the setting of the sphere in the cable from the ground.Then, it is lifted by a second operator at the top of the tower of transmission, which places it in the cable.The first operator pulls the sphere by means of the rope, to the point of the cable where it is to be fixed.Hit the point, the operator releases the rope lug of drag (2) and she pulls the trigger (3), disarming device for opening / closing, which closes the sphere, and in the cable.To remove the sphere of the cable, use the traction rod (Fig.4), on which is affixed to garatu00e9ia (Fig.5), which is attached to the cable transmission line by the operator is in the tower and dragged by means of a rope until the ball by the operator who works on the floor.There, maneuvering the garatu00e9ia through rope, the operator makes a their rods (33) fits the drive cable (6).By pulling the drive cable (6) with the aid of garatu00e9ia operator, the gun, the device for opening / closing of the sphere, opening it and allowing him to pull it out with the aid of rope.Until the tower of the transmission line, where the operator is in the tower to remove the cable.
