Abstract

The invention relates to the sinking of underground structures by mechanical means using drilling machines. The goal is to increase the efficiency of the device due to a more complete and cost-effective mechanization of penetration by solid slaughter. The device contains a drill in the form of a rod 2 with a drilling nozzle, a wedge mechanism (KM) and a drive rod 2 and KM. The latter is made in the form of a loose mustache.

Description

 The invention is relative to the RR: the walk of the subfloors of the construction of W1. Computational affinities with the use of basic machines can be used by IOIP to destroy the massif of well-welded rock formations TI v the erection of the tunnels and ayraboyuk

The purpose of the invention of PSE s: the development of the work of the device: at the expense of more shelf / 1 economical 1 can be continuous: aboea

The ring is freely rotated by the cam and, for ease of installation, has a slit (lock), and the outer surface is wedge-shaped for better penetration into the rock. The left end of the tubular shaft has a thrust flange and a lever that the contactor can be rotated by mounting the rings on the shaft with zero eccentricity and the tubular shaft is inside boreholes, well, due to friction

0 shaft with an array along the contour of the well allows, applying a force from the bottom of the well to the thrust, to squeeze the rock into the face with a contactor. The thrust, as noted, consists of a drill cone at the end of the rod, passing inside the tubular shaft of the contactor. At the other end of the rod, a large-diameter drum is fixed, on which a resistant thread is cut. A gear with a stop casing is screwed on this thread, driven into rotation by a screw. The housing through the thrust ball bearing rests on the flange of the tubular shaft. When the screw is rotated and the drum is locked, the gear with the casing moves to the left along the drum threads, and the casing with great force presses against the flange of the tubular shaft, which squeezes the rock mass into the bottom.
