DRILLING MODULE OF SHAFT DRILLING RIG

摘要

FIELD: mining. ^ SUBSTANCE: drilling module of a shaft drilling rig comprises an arrow-shaped manipulator, a drilling machine and an assembly board. The arrow-shaped manipulator comprises an arrow and two control hydraulic jacks connected to the assembly plate by ball or cardan joints and providing for the possibility of angular rotations of the arrow jointly with the drilling machine in the vertical and horizontal directions by means of two control hydraulic jacks distanced at spatial angles to each other and attached to the arrow by single hinged joints. Rotations of the arrow in the vertical plane are carried out by control hydraulic jacks in process of their synchronous operation, and in the horizontal one - in process of their differently directed movement. The directed movement at angular rotations of a drilling machine relative to the arrow of the arrow-shaped manipulator is carried out by means of a hydraulic jack joined by single hinged joints with an arrow and a drilling machine, and also with the help of a double-fork hinged bracket mounted on the front end of the manipulator arrow. ^ EFFECT: expanded drilling area from one position of a shaft drilling rig and higher efficiency of drilling works when tunnelling vertical shafts by a drilling and blasting method due to manoeuvrability and independence of operation of separate drilling modules mounted on a single shaft drilling rig. ^ 4 dwg
