Description

one

The invention relates to drilling equipment used in the mining industry, and specifically to aggregates for drilling uphole mining workings.

The purpose of the invention is to reduce the energy intensity of the destruction during the drilling of 3 strong rocks.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The device for excavating the excavation workings consists of a rotator with cartridges 3 and a drive 4, a control console 5, a spacer column 6, standing with a rod 7. with a hole 8, a swivel 9, an air supply sleeve 10 and a working body II with pneumatic impactors 12 and 13, traversing I4, holders 15, crowns 16 and 7, core maker 18, having fins 19, air supply channels 20 and 21.

I.

In addition, the device consists

from the Upper horizon 22, the advanced well 23, the lower horizon 24, the ring pillar pillar 25, the outer end of the slot 26.

The device works as follows.

A column 6 is fastened on the upper drilling horizon 22, on which the rotator 1 with the cartridges 2 and 3 and the control panel 5 and the actuator 4 is fixed. In the cartridges 2 and 3, the drill rod 7 is mounted, to which the air suspension 293522 is attached

the sleeve 10 through the swivel 9, and in the front part - a hammer hammer with a crown (not shown) for drilling an advanced well 23. After

5 outputs of the advanced well 23 to the lower horizon 24 from the stand of the rods 7 disconnect the hammers from the crown, and in its place the working organ P is installed, on the periphery of the traverse 10 which 14 on both sides install No. 1 pair of hammers 12 and 13 along the helical line relative to the axis of the rods 7. The pneumatic antidotes 12 and 13 are mounted on holders

L5 15 within the slit at an angle of 2-4 ° so that the crowns 16 are touching with the cutting edge only the walls of the ring rear sight 25, and the crowns 17 - only the outer contour of the slit 26.

20 Crowns 16 and 17 have the shape of a truncated cone with a cutting edge on a large base and rotate freely in the hammers 12 and 13 due to one-sided contact with the walls 7 .5 of the slot 26. Since the impactors have a helical inclination between 20 and 40 during their operation reactive tangential forces arise. facilitating the rotation of the working

3Q of the organ 11 by the rotator 1. Air supply to the pneumatic hammers 12 and 13 is carried out through the hole 8 and the channels 20 and 21. The ring rear sight is destroyed by the ribs 19 of the coremathod 18 as the annular gap protrudes. The pass-through endframe is completed when the working body 11 reaches the upper horizon 22,

Claims (2)

1. DEVICE FOR PASSING RISING PRODUCTS, including a rotator, becoming a hollow rod and a slit-forming working body with a core breaker, a traverse, with a cavity for supplying air and mounted on the ends of the traverse obliquely to the opposite direction of rotation of the rod, pneumatic hammers with crowns, which differs that, in order to reduce the energy intensity of fracture during drilling in strong rocks, the hammers are split by crowns in the radial direction in different directions relative to the axis of the slot, and the crowns are made in the shape of a truncated cone with a cutting edge on the large base of the cone and mounted with the possibility of free rotation in the body of the hammer. 2. The device according to claim 1, characterized in that the hammers divorced in a diagonal direction at an angle of 2-4 in each direction. SU „„ 1229352
