Abstract

On hydraulic-driven box-frame-type manipulators, the 'Y'-trough machine interface hydraulic hoses and electrical cable are required to move back and forth along the machine axis, sometimes as far as 60 inches. Due to this continuous movement, and flexure of these hoses and cable, both hose wear and cable conductor failure have been a chronic problem. These problems have been overcome by enclosing the hydraulic hoses 10 in a segmented plastic track 12 and terminating the hoses at a manifold by means of swivel joints 14. These joints 14, which allow rotation under hydraulic pressure, minimize the bend radius to which the hoses 10 are subjected, and by enclosing the hoses 10 inside the plastic track 12, abrasion by the trough panels is eliminated.

Sliding Ribbon Y-Trough Cable

On hydraulic-driven box-frame-type manipulators, the 'Y'-trough machine interface hydraulic hoses and electrical cable are required to move back and forth along the machine axis, sometimes as far as 60 inches. Due to this continuous movement, and flexure of these hoses and cable, both hose wear and cable conductor failure have been a chronic problem. These problems have been overcome by enclosing the hydraulic hoses 10 in a segmented plastic track 12 and terminating the hoses at a manifold by means of swivel joints 14. These joints 14, which allow rotation under hydraulic pressure, minimize the bend radius to which the hoses 10 are subjected, and by enclosing the hoses 10 inside the plastic track 12, abrasion by the trough panels is eliminated. The electrical cable previously used is of the standard round cross section, housed in a plastic jacket. This cable is of fairly rigid construction, and the continual flexing of the cable causes stress failures of the conductors. This article proposes a flat ribbon cable 16 that is attached to the plastic track 12 by means of clips 18 which are held in position by screws. These clips 18, with the exception of the first and last clips, permit the cable to slide across the upper surface of the plastic track 12 as the machine 'Y'-axis joint moves through its normal travel. By allowing the ribbon cable 16 to slide instead of being held in a fixed position, the dimensional difference caused by the...
