Description

The invention relates to the mining industry, in particular, to installations intended for drilling sets of fan and parallel wells during the mining of deposits by the underground method.

The aim of the invention is to expand the operational capabilities in drilling parallel wells and simultaneously reduce the labor intensity of auxiliary operations.

FIG. 1 shows a machine, side view; in fig. 2 - the same, front view; in fig. 3 is a section DD in FIG. 2 (node of auxiliary support for the beam of the auto feeder based on additional elements of the quick-release hinge joint) in fig. 4 shows the section EE of FIG. 1 (an assembly unit for the beam of the automatic feeder and the adjustable rod with the column); in fig. 5 - crosshead assembly, longitudinal section; in fig. 6 is a cross section of AND-AND in FIG. 5, (crosshead assembly in cross section); in fig. 7-10 - constructive use of U 00

machine tooling (options); in fig. 11 is a section to K — K in FIG. ten; Fig. 12 is a variant of the quick-release swivel elements.

The drilling machine consists of a base 1, 5 made in the form of a sled, a carrier block in the form of a spacer 2 with a power rod 3, two movable couplings 4 and 5 and two crossheads b and 7, a drill head 8 and an automatic beam 9 10 by one of the quick-swivel (conical flange) element 10. through a similar additional element 11 and the tightening collar 12 is aligned with the coupling 4 mounted on the column 2c 15 by the possibility of longitudinal movement, rotation around the axis of the column 2 and fixing on it.

Traverse b (Fig. 5) at one end through one of the conical flanges 13 20 and 14, namely the conical flange 14 and the tightening collar 15, contacts the coupling 4, and the second end rests on the protective case 16 of the spacer head 17, equipped with a fifth 18. A nut 19 of the tip 25 17 through the distance tube 20 rests directly on the sleeve 4 and is fixed (not shown) on it from turning. The cross member 6, when loosening the collar 15, can be rotated exactly on a goal of 180 ° at 30 by means of the stops 21 and 22 (Fig. 6), made on the surfaces of the inner holes of the conical flanges 13 and 14, respectively.

The traverse 6 is made with a longitudinal key 23 fixed on it, the side 35 surfaces of which are in contact with the walls of the longitudinal section of the coupling 5, which covers the traverse 6 and is installed with the possibility of longitudinal movement and fixation from the clamp of the bolts 24. Thus, the coupling 5 is fixed against rotation on the yoke b key 23, and the yoke 6 - from turning around its longitudinal axis and fixed by the collar 15. The yoke 6 on the side of the support on the body 16 and the distance 45 tube 20 can be extended by nozzles along the length (not shown) on the basis of p spanner joint. The traverse b is connected to the column by means of a sleeve 4.

Coupling 5 is equipped with a conical flange 50 25 (quick-release swivel element), which can be combined with a similar conical flange 10 (Fig. 1 and 2) of the automatic feeder 9, the specified combination is ensured by the fact that 55 in the lower part of the spacer column 2 is mounted , can be rotated around the axis of the column 2 and fixing the crosspiece 7 for an additional coupling, with a unified fixed on it

for the entire machine, an additional element 26 of the quick-release swivel (conical flange), which can be combined by means of a tightening collar 27 in the form of a hinge with the additional element 28 of the quick-release articulated joint (conical flange) fixed on the automatic feeder 9

Moreover, element 26 is installed in such a way on traverse 7, that its axis A-A of relative rotation in the hinge with element 28 and collar 27 is separated from the longitudinal axis B of column 2 at least half the distance between axis C-C relative rotation in the hinge (10, 12, 25) of the element 25 of the quick coupling, mounted on the coupling 5, shifted to the position closest to column 2, and the longitudinal axis bb of the latter; the feature also determines the equality of the distance between the elements 10 and 28 on the beam-feeder 9 and between the elements 25 and 26 (the first at the closest position to column 2 of coupling 5) and is specified by the fixing point of the cross bar 7 on column 2,

The free planes A of the elements (11, 25 and 26) to the corresponding elements (10 and 28) of the automatic feeder beam 9 are oriented in the same plane. The clutch 4 is made split with the possibility of folding with hinged bolts 29 on the column 2, and the width of the slit B of the clutch 4 is greater than the corresponding dimension of the hinged connection of the column 2 and the adjusting rod 30.

In the described embodiment, a drilling machine with a rod unwrapped into the development arch (Figs. 1, 2), when the automatic feeder 9 is in position, combined with the coupling 4 by means of a quick-swivel joint 10, 11, 12, allows drilling of fan-like sets of wells in a cross section plane production or around it, within the regulation of the angle of inclination of the column 2 th 30 th.

When drilling a set of parallel wells oriented vertically in the cross-section of the mine, the central well of 1 set of drillings is from the position of the automatic feeder 9 fixed by clamp 12 on the sleeve 4 of column 2 at a given angle of inclination of all wells in the plane of the kit, for example, 90 ° to the ground development,

The drilling of peripheral wells II to the right of the central well (Fig. 2) is provided by translating and securing the automatic feeder 9 on the sleeve 5 (conical flanges 10 and 25 are covered by the collar 12), which is fixed in the desired position

the length of the traverse 6 across the width of the section of production.

The conversion of the beam-top sensor 9 from the coupling 4 to the coupling 5 of the crosshead 6 is carried out as follows.

After drilling the central hole 1, the tightening of the collar 12 is loosened, and by turning the automatic feeder 9 counterclockwise, its element 28 is aligned with element 26 on the second yoke 7 and connected with their collar 27 without fixing relative to each other. Then, the clutch 5 is moved to the closest position to column 2 and the collar 12 is removed from the elements 10 and 11, by turning the automatic feeder 9 relative to the quick-detachable swivel 16, 27, 28 in a clockwise direction, its element 10c is aligned with element 26 and they are tightened with a collar 12. Finally, the tightening collar 27 is removed from the elements 26 and 28, the automatic feeder 9 is deployed in the direction of drilling 3 in the set, the elements 10 and 25 are fixed by the tensioning clamp 12 and by moving the coupling 5 along the cross bar 6 automatic feeder 9 n and a new well I set. Fix the clutch 5 relative to the traverse 6.

In order to ensure reliable alignment of the hinges of quick-hinged joints along the axes 10 and 28, each of the elements 10 and 28 of the composite spring-loaded piston-centralizer 32, which, under the pressure of compressed air supplied through line 33, extends over - the plane plane A and enter into the corresponding hole on the element being joined, for example element 11, - and is held until the clamp 12 or 27 is tightened. After that, the compressed air is turned off and the spring 31 returns the piston-centralizer 32 to its original position.

The conversion of the automatic feeder 9 to the left half of the column 2 of the output section is carried out as follows.

The horizontal traverse 6 is thrust into the production side and the coupling 4 is fixed against column 2 (the coupling 4 is held along the height of column 2 on chain 34, the end of which is fixed to the upper end of column 2), traverse 6 is rotated around column 2 before installation its in the left half of the section of production (Fig, 2, dash-dotted).

In the intermediate position, the crosspiece 6, oriented along the axis of the working, rotates the automatic feeder 9 relative to the C – C axis (FIG. 6) at an angle of 180 °, after which the elements 10 and 28 are fixed relative to each other by the collar 12. After the horizontal crosshead expands 6 in the left side of the production slightly release the clamp 15 and (in view of the design features

traverse 6 with stops 21 and 22 on the conical flanges 13 and 14) rotate the beam-automatic feeder 9 around the longitudinal axis of the traverse 6 exactly at an angle of 180 °. while its expansion system (pos. 17-20) remains stationary

0 (Fig. 5). As a result, the self-feeder beam 9 is installed in the plane of drilling of the set of wells, and specifying its position in the direction of drilling of the wells in the set is established by turning and fixing it on a swivel joint (pos. 10,12, 25), moving the coupling 5 with subsequent fixation on the traverse 6 clarifies the position of the auto-feeder beam 9 in a particular direction of the well.

0 After drilling a well in the left half of the output section, shear sleeve 5 moves to the closest position to column 2, unload the traverse bars 6 and disperse the column 2.

5 Moving the machine to the position of a new set of parallel wells, re-expand column 2 into the production well and traverse 6 into its left side and fill the left side of the set of parallel wells. Next, by the described (only reverse) order of the operation, the beam-automatic feeder 9 is transferred to the later part of the output section, then, in the same way, the described operations are transferred

5 an automatic feeder 9 on the sleeve 4 for drilling the central well of the set

The drilling of sets of parallel wells oriented horizontally in the section of production can be carried out as follows. Traverse 6 and 7 are removed from the column. The beam-automatic feeder 9 on the coupling 4 is turned into a horizontal position or a position that is slightly different from it and fixed by means of a clamp

5 12 through elements 10 and 11. Chain 34 is re-secured with a taut tip on the power rod 3 columns 2, which are positioned in the lower position if lifting of the automatic feeder 9 is necessary. After this, release the coupling 4 on column 2, which hangs on chain 34 The mechanized lifting of the power rod 3 leads to the raising of the automatic feeder beam 9 to a new horizontal level by means of a chain

5 34. If the upward stroke is not enough, fix the clutch 4 to the column 2, lower the power rod 3, re-fix the tension of the end of the chain 34 on it and repeat the operation of lifting the automatic feeder 9 to the required height

The presence of the gap B (Fig. 4) in the split design of the coupling 4 for clamping it on the column 2 allows the swivel assembly of the column 2 with the adjustable thrust 30 to pass through when the bolts 29 are dropped, which allows the entire length of the column 2 to be used to move the beam automatic feeder 9 on the height of production. To descend the auto-feeder 9, the end of the chain 34 is re-secured to column 2 with an overlap that allows the automatic beam 9 to descend to a certain height, then release the coupling 4 against the column 2 for smooth descent of the automatic feeder 9 to complete tensioning of the chain 34. After that, again fix the clutch 4 on column 2.
