Abstract

Usage: the mining industry and can be used for tunneling tunnels with the possibility of mining at any point. SUMMARY OF THE INVENTION The tunneling unit has a rock cutting member with a cutting drum, which is mounted for lateral movement in horizontal guides by means of horizontal hydraulic cylinders. A support ring with vertical guides on which horizontal guides and vertical displacement cylinders are mounted associated with a rock cutting member. Segment-shaped frames, horizontally fixed: between the upper and lower bases of the vertical guide columns, and axial and radial expansion cylinders. The axial thrust cylinders are fixed in the support ring. Hydraulic cylinders of radial expansion are fixed on a segmented frame in the plane of the upper base of the vertical guides. Supporting rollers are mounted coaxially with the cutting drum with the possibility of interacting with the path of the support ring of the support ring. 2 ill. with

Description

The proposed solution relates to the field of mining and can be used in the excavation of inclined mines.

The purpose of the invention is the ability to develop a bottom at any point and to provide a given output contour.

This goal can be achieved due to the fact that the device is equipped with a support ring with vertical rails, on which horizontal rails are installed, with vertical hydraulic cylinders,

associated with a rock-breaking organ, segmented frames horizontally fixed between the upper and lower bases of the guide vertical columns, axial thrust cylinders fixed in the support ring, radial thrust cylinders mounted on a segmented frame in the cavity of the upper base of the vertical guides, and the support a roller mounted coaxially with the cutting drum with the ability to interact with the copy track made on the support ring.

In FIG. 1 - general view of the driving unit; in FIG. 2 - view along the arrow.

The driving assembly includes a support ring 1 inside of which hydraulic cylinders 2 for feeding it to the face, hydraulic cylinders 3 for axial thrust and hydraulic cylinders for radial thrust 4 are segmented frames 5 and b, fixed between the upper and lower bases of the guide columns 7 for vertical movement of the horizontal guides 8. Telescopic hydraulic cylinders 9 are pivotally connected on one side with a horizontal guide 8, and on the other with a segmented frame 6, the lower base of the guide vertical columns 7, per The rock-cutting body 10 is positioned in the horizontal guides 8 by telescopic hydraulic cylinders 11, and the support roller 12 is mounted coaxially with the cutting drum 13, which interacts with the tracing path 14 made on the support ring.

The driving unit works as follows:

The horizontal guides 8 for lateral movement and the rock cutting body 10 are lowered by telescopic hydraulic cylinders 9 to the lowermost position of the contact of the support roller 12 and the copy path 14 of the support ring 1. In this case, the axial thrust cylinders 3 are advanced forward to contact the rock face. Then, the drive of the rock cutting body 10 is turned on and the feed cylinders 2 support ring moves to the bottom. At this point, the cutting drum 13 is drilled into the rock. When moving the support ring 1 to the bottom, the hydraulic cylinders 3 of the axial thrust are automatically reduced while holding the support ring in a predetermined position.

After the drilling of the rock cutting body 10 has finished, the radial expansion cylinders 4 extend, which together with the axial expansion cylinders 3 stabilize the support ring in the working.

The cutting drum 13 of the rock cutting body 10 is developing the lower contour of the cross section of the mine, when

the support roller 12 is in contact with the copy path 14 of the support ring 1.

Subsequent development of the production cross section by the crack-destroying organ 10 is carried out by moving the horizontal guide 8 along the vertical guide columns 7 using telescopic hydraulic cylinders 9.11. At

In the development, loading of the broken rock is carried out in the space between the vertical guide columns 7 and the lower segment-shaped frame 6.

According to the development of pedigree

as the cutting drum 13 approaches the axial thrust cylinders 3, they are automatically retracted. At the end of the development of the cutting drum of the bottom, the axial thrust cylinders 3 extend to contact the face.

After the development and loading of the broken rock, the lining of the excavation is installed, and then the hydraulic cylinders 4 of the radial expansion are removed and the cycle repeats.
