LOWER HYDRAULIC MORSA, WITH SAFETY AND REGULATION SYSTEM IN THE POSITIONING OF THE DRILLING ROD OF GEOLOGICAL RIG EQUIPMENT

摘要

lower hydraulic vise, with safety and adjustment system in the positioning of the drilling rod of geological drilling equipment. where a lower vise working together with the upper vise, acts as a safety element during the stem breaking stage. the lower vise, due to its mobile and fixed carcasses, is installed on the drilling rig platform and interconnected to the probe's hydraulic system and, in case of failure in the hydraulic system and the upper vise opens unduly when the stem set is released by winch, a set of springs installed between the mobile and fixed housings keeps jaws mechanically locked, preventing the drilling tool from falling into the hole already made in the rock. the lower vise will also assist in securing hoisting with the probe recessed from the running hole, thus eliminating the risk of accidents and damage to the whole of the drill rods with the use of hand tools, improving ergonomics and operator comfort, adjusting, also, to the inclinations of the drilling equipment for the work of the rod in holes with an angle of up to 60 198.
