FIELD: drilling.
SUBSTANCE: group of inventions relates to drilling devices and, in particular, to a device for drilling and installation of an anchor support, for making a borehole and introduction of a bolt to a borehole from the surface of the rock formation. The drilling device contains a main frame, a supply frame installed with the possibility of movement relatively to the main frame, and a supply device for introduction of a drilling element from the surface to the formation. The main frame contains a pair of hydraulic cylinders. The supply frame passes along a supply axis and contains a set of guiding rods installed in parallel to the supply axis. The supply device is installed with the possibility of movement relatively to the supply frame in the direction parallel to the supply axis. The supply device contains the first guiding element and the second guiding element installed from opposite sides of the supply axis relatively to each other. The first guiding element interacts with the surface of at least one of guiding rods, and the second guiding element interacts with the other surface of at least one of guiding rods. In this case, the first guiding element has a concave shape and contains the first recess receiving the first edge of at least one of guiding rods. The second guiding element has a concave shape and contains the second recess receiving the second edge of at least one of guiding rods.
EFFECT: increase in the efficiency of drilling and installation of an anchor support.
