摘要

LOWER HYDRAULIC DIES, WITH SAFETY AND ADJUSTMENT SYSTEM IN THE POSITIONING OF GEOLOGICAL DRILLING DRILLING ROD. Where a lower vise working together with the upper vise acts as a safety element during the stem breaking step. The lower vise, due to its movable and fixed casing, is installed on the rig rig and interconnected with the probe hydraulic system and, if the hydraulic system fails and the upper vise opens improperly when the rod assembly is released by winch, a set of springs installed between the movable and fixed casings keeps mechanically locked jaws, preventing drilling tool from falling into the hole already drilled in the rock. The lower vise will also assist in securing the spindle with the recessed drilling hole probe, thus eliminating the risk of accidents and damage to the plumbing rod assembly with the use of hand tools, improving ergonomics and operator comfort, adjusting further to the inclinations of the drill rig for rod work in holes up to 60 198.
