Abstract

The invention relates to the field of mountain production and improves the reliability of the machine. It includes a drill head (BG) 1 with a sled, a feed mechanism 2, a frame 3, a drilling rig 4, supported by end 5 and movable 6 lunettes (L) and a displacement and fixation mechanism L 6. It is designed as a spring-loaded a single-arm lever, a copier and a profiled stop, is installed- Hbix on frame 3 and a spring-loaded retainer (F) and stop mounted on L 6. During drilling, BG 1, moved by feed mechanism 2, moves L 6 in the direction of drill. The lever interacts with the copier and captures L 6 for the emphasis placed on it. In this case, L 6 will unlock, come off the profiled stop and rigidly connect to the IG I by means of a lever. The return of BG I to the initial position occurs together with L 6 before they are disconnected. In this case, the lever interacts with the cam and comes out of the engagement with emphasis on L 6. At the moment of disconnection, F is in. the area of fixation profiled stop. As a result, reliable fixation of L 6 in a predetermined position occurs. 3 il. i (О С N0 00 (h | C) 0 0f / e.f

Description

This invention relates to a mining field, in particular, to drilling machines for drilling bore-holes and carrying out underground mine workings.

The aim of the invention is to increase the reliability of drilling operation.

Figure 1 shows a pre-fired boring machine; on fng.2 - node I in figure 2 ;; in FIG. 3, section A-A in FIG. 2

The boring machine includes a drill head 1, a feed mechanism 2, a frame 3, a drilling stand A supported by 5 and a movable 6 lunettes and a mechanical movement and fixation mechanism of the backrest. The latter includes a spring-loaded single-shouldered lever 7, mounted on the sled of the drill head 1, a copier 8 on the frame 3, an emphasis 9 and a profiled emphasis 10 ,. fixed on the frame 3, and under the spring-loaded lock and on the movable rest 6.

Drilling machine / machine works as follows.

The drill head} under the action of the feed mechanism 2, moves in the direction of drilling. After reaching the movable lune. 6, the drill head I begins to move it in the same direction. the board. In this case, the spring-loaded single-arm lever-7, interacting with the cam 8, produces a grip on the moving lunette for the stop 9. Since the feed force during the buren far exceeds the clamping force of the spring-loaded latch M, the mobile unit 6 comes off the shaped stop 10. The mobile lunette 6 has turned out unlocked and connected

rigidly with one arm 7 with a drill head I.

When the drill head 1 returns to its initial position, the movable rest 6 also moves with it. The joint movement of the Jypilny head I and the rest 6 occurs until they are disconnected due to the fact that the spring-loaded single-arm lever 7, interacts with the copier 8, rises and leaves the link with the stop 9 of the moving lunette 6. Since the spring-loaded latch 11 at the time of disconnecting the drill head and the lunette 6 is in the fixation zone of the profiled stop 10, reliable fixation of the moving lunette 6 occurs in a given lying.
