(54) UNDERGROUND DRILLING MACHINE

:. ., I

The invention relates to the field of the mining industry, in particular to sub-drills of drilling machines for use in underground conditions.

A roller drill machine is known that includes parallel guides: carriages, rotator, sourced with a cross-beam flexible link, crossed through, rollers.

However, in such a machine is not sufficiently secure the flexible elements.

The closest solution to the technical essence and the achieved result is an underground roller cone machine, which includes parallel hydraulic cylinders of the feeder, connected by traverses with blocks for flexible elements, connecting the rotator of the machine with pistons, the tension mechanism of flexible elements, and their assembly on the rotator And piston 2.

This machine has a complex structure and insufficiently reliable fastening of flexible elements.

The purpose of the invention is to simplify the structures.

For this, the rotator is mounted on numerical bridges with the possibility of axial displacements, the tensioning mechanism of the flexible element is placed on the block, the axis of which is installed with the possibility of displacement through the wedge along the feeder, and the fastening unit of the flexible elements is full of gear teeth, and the cavities of which are on the gabkom element and the fastening dies, which are mounted 10 in 1 in the piston in the rotator.
