Abstract

FIELD OF THE INVENTION The invention relates to mining and is intended for the destruction of rocks, in particular coal, by separation from wells. The purpose of the invention is to increase the productivity of the destruction of rocks by combining the operations of drilling and separation. The device consists of an external cylindrical sleeve (CV) 1 with a longitudinal through cut on the side of the location of the drilling machine 16, coaxially mounted on the drill rod (BS) 2 with a crown 3. External CV 1 is rigidly connected to the non-drying frame (HP) 5. The diameter of the CV 1 is smaller than the diameter of the crown 3. In the CV 1, the BS 2 is installed internally with the CV 6, with the possibility of longitudinal movement relative to CV 1. On the outer surface of the CV 6 on the side of the longitudinal cut, a longitudinal wedge is fixed to a rigidly longitudinal cheeks 18 with the possibility of extension when interacting with an donkey 8. External TsV 1 is connected with the rod 9 of the power cylinder 10 by disks 11, 12 and straps 13. The power cylinder 10 is mounted on HP 5 by means of a rack 14 and a hinge 15. The boring machine 16 is fixedly mounted on HP 5 axially BSh 2. Rotation of BSh 2 in lantern 4 occurs simultaneously with the movement of CV 6 with wedge 8, discs 11,12 and straps 13. Wedge 8 acts on the areas of 19 cheeks 18. Cheeks 18 from through cuts turn around hinges 17 The rock mass is being pulled out. 4 il. i (Л С 1 g

FIELD OF THE INVENTION The invention relates to mining, namely to means of destroying rocks, in particular coal, by separation from wells,

The aim of the invention is to increase the productivity of rock destruction by combining drilling and tearing operations.

Figure 1 shows the proposed device, a general plan view of FIG. 2 - the same, side view; figure 3 is the same, the view from the side of the boring machine; figure 4 - wedge rip, cross section.

The device consists of an external cylindrical sleeve 1 with a longitudinal through-cut, coaxially mounted on a drill rod 2 with a crown 3. At the end of sleeve 1 a carrier lamp 4 is installed, through the axial hole of which the drill rod 2 is passed, the Sleeve 1 is fixed (rigidly) mounted The supporting frame 5. In the outer sleeve 1, an internal cylindrical sleeve 6 is coaxially attached to the rod 2 and longitudinally displaceable relative to the sleeve 1 and the drill rod 2. The outer surface of the sleeve 6 is rigidly longitudinally mounted PORN wedge (elements 7 and 8) by using the disc 13 and the tie-rods of the longitudinal recess of the sleeve 1. The sleeve is coupled with the rod 9 of the actuator 10 drive the wedge otryvnika (comprising the sleeve 1 and 6, and rastsorny wedge (razdvizheniya cheeks).

The power cylinder is mounted on the supporting frame 5 by means of a rack 14 and a hinge 15. The boring machine 16 is fixedly mounted on the supporting frame of an axially associated drill rod. The connection of a drilling machine with a drill rod can be made in the form of a gear or chain transmission, for low power - in the form of a universal joint shaft or flexible shaft from the engine to the axis of the rod 3. On the lamp 4 in the longitudinal through cut of the sleeve 1 with sliding joints 17 are installed 18 with the possibility of extension when interacting with inclined pads 19 with elements 7 and 8 of the wedge.

The sleeve 1 has a diameter smaller than the diameter of the crown 3. A longitudinal through cutout of the sleeve 1 is located on the side of the drilling machine 16.

The device works as follows.

Rod 2 g with crown 3 is rotated by machine 16, while diameter of crown 3 is larger than diameter of sleeve 1, and drilling machine 16 moves with frame 5 after the well has been drilled, a drive 21 turns on for rod length 21 and simultaneously with rotation of rod 2 in the lamp 4, the sleeve 6 moves with elements 7 and 8, discs 11, 12 and straps 13, while elements 7 and 8 act on the pads 19 of the cheeks 18, extending the last of the through cuts by turning around the hinge 17, as a result of which the mountain masses. At the stroke of the stroke, the sleeve 6 returns to its original position by returning the rod 9 to the cylinder 10, while the entire system, including the frame 5, continues further movement along with its rod 2 along its axis. Consequently, two operations occur simultaneously; and: continuous drilling of the well and reciprocating movement of the sleeve 6, followed by separation of the rock mass. The deviation of the cylinder 10 from the straightness is achieved by the hinge 15 on the rack 14.
