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.The present invention relates to a device for opening closing of the spheres of signals, which allows its installation in cable (38) of the transmission network, as well as withdrawal.From the ground, avoiding the use of helicopters, or the need for displacement of the operator through cables.The ball has an internal device driven by a compression spring (14) which maintains the two semi sphere bottom (2) and upper (1) open.Allowing the ball to be placed on the cable (38), which will then be fixed, and pulled by a rope fixed in the eye of drag (22) and in the lower lug (20), from the ground.To the point where it will be fixed. Then, the operator maneuvers the rope to release the splicing of drag (22) and with the aid of her, pull the eye less (20), closing the sphere.To remove the sphere of the cable (38) is to use the traction rod (FIG. 10), to which it is affixed to garatu00e9ia (Fig.9), which is attached to the cable (38) of the transmission line and driven by means of a rope to the sphere of signalling by an operator that works on the floor. There, maneuvering the garatu00e9ia (Fig.9) through the rope, the operator makes a their rods (24) fits in the eye (19) of the actuating lever (18, 19, 20).By pulling the actuating lever (18, 19, 20) with the aid of garatu00e9ia (Fig. 9), the operator of the soil makes it back to its position of origin, opening the sphere.Open the sphere, she gets loose in the cable (32) and can be dragged to the tower of the transmission line, where it will be removed from the cable (38).
