Device for whale drilling.

The invention "relates generally to devices for drilling shafts, especially on drilling devices with an upper bezel, which is clamped to the landings ^ of the shaft and to which ■ "_. a number of next pointing rock drill bits hung up are. The suspended ends of the pushbuttons operated by pressure means, which are preferably in the Kind are designed that they are by pressure medium force Can sit on trolleys or be withdrawn such units that run on the ring. The- - Holes. Are usually in. Pyramidal cut attached, the rock drills are firmly connected to each other

and lie parallel to the tusk-legs. During V ^r advantage of such Yorrichtungen-consists in that they give a better connection between "in the operating position the ring and the shaft bottom, the most vertical outermost holes of the pyramid section require an assembly of the ring close to the walls -. Of the well to a To enable the end of the running frame of the push legs to be arranged vertically above the outermost holes to be drilled. However, since many manholes are lined with concrete or other material of considerable thickness, an undivided manhole ring, which usually has the diameter of the unwalled It is impossible to raise the shaft to the required height to enable a safe blast, so that a lot of time is lost to dismantle the drilling unit and reassemble it again after the blast, --v. -.. -

The invention has therefore set itself the task of providing a Device for drilling mine shafts of the aforesaid. Art to create, with a free passage for the AbrausLfcfibel-to the shaft bottom is provided while the whole drilling device, without having to be disassembled, into the bricked wedge of the shaft in safe height can be raised.

For this purpose, a pit drill ring is used according to the invention provided, which is designed in such a way that it is used as a carrier for part of the supply lines for the Pressure medium is used to drive the rock drill.

The erfihdungsgemäße ring for drilling τοπ- Grubenschäehten - - ^r is intended to be strong and durable, and such ..-: shape, in that at random it to bounce ^v incident lelsbrocken without damage to the underlying lines in it during the blasting.. -.....- ".

A device according to the invention for drilling mine shafts has for this reason βίηβη carrier, the an annular running rail forms which at a considerable distance from the walls of the pit runs, with adjustable supports on this carrier are provided, whereby the running rail is practically horizontal over the. Shaft bottom on; the walls of the Schachtes festklemmbsr is while several trolleys are arranged on this running rail along the carrier each of which has a vertical pivot, on which arms running transversely to the shaft can be swiveled; \ are arranged, which in turn at the extreme end articulated buttocks with attached Geateinsbohrern wear, which are directed downwards on the sole of the sheep -are. .

The embodiment shown in the figures of The drilling device according to the invention is here designed for use in circular mine shafts 10. The shaft can be provided with a concrete lining 11, which after, and after is introduced with the help of a mold 12, which on corresponding lifting arrangements, which, however are not shown, is suspended. The work on the bottom of the sight runs in the non-lined shaft at a safe distance from the form 12. the boreholes in the usual pyramid shape is provided a visual ring 15, the diameter of which is much smaller than that of the shaft 10. This-. Hing consists of three sections 16 '- "16'" · '.. The individual Sections have transverse ends at their ends End plates 18 on (Figure 4), through which corresponding Connecting bolts 17 are pulled so that the three parts can be screwed together. Each section consists of conically curved plates 19, 20, which are connected, for example, by welding to a sub-ring section 21, so that three such Segments with a substantially Y-shaped cross section arise. Is at appropriate intervals from each other a number of webs 22 with the opposite

"" "" lying 'plates; 19, 20 des__ Ringet 15 welded :. In these webs 22 are ring eyelets 23 used, in Y / elche Cable-24 for lifting the ring 15 to the desired. Hohen; are suspended in shaft 10.

In the ring segments 21 three pivot pins 25 are used at a distance of 120 °, each one horizontal Wear sleeve 26 which has an inner bore 27. This bore 27 slidably receives the body 28 a "support, for example a screw clamp, its displaceable member 29 sliding, however, not is rotatably mounted in the sleeve. The extendable part 29 has an internal thread into which a Screwsp3-n.de 1 31-engages, which through the end wall of the body 28 passes through it and a sprocket 52 carries. This chain wheel 52 can be rotated by a chain, whereby the sliding piece 29 as desired can be extended or withdrawn. A transverse pin 24, which cooperates with a number of notches 35 in the support body 28, goes through the Sleeve 26 therethrough; and locks the support body 28 therewith.

For proper locking of the sleeve 26 with the Manhole ring 15 in. Corresponding angular positions are on both sides of each pivot 25 two eyelets 37 » provided, which, for example, with the inside of the Plate .20 in Figure 3 and 4- are welded. the Sleeve 26 has a single eyelet 4O- which. By pivoting the screw clamp alternately with a

-β

the eyelets 37 and 38 can be brought into line, and -with "these" through; a Sieheruhgszapfen 41 locked - ^ can be. If the eyelet 40 is locked with the eyelet 37, is the screw clamp radial to the inlet 15, while they are tangential to the ring when locked with the eyelet 38 lies, as shown in dashed lines in FIG.

■ To fix the input in the working position in the shaft -TO, the ring up to, for example, 3m above the ■ shaft bottom raised, whereupon the screw clamps 28 in be locked by the pin 41 in the radial position. This will bring up the sprockets. 32 twisted to the Sehiebestüeke 29 firmly in the walls of the shaft pressed in and thus a perfect support of the ring 15 to achieve.

The upper edges of the plates 20 of the ring 15 serve as running rails for wheels 36 which are rotatably mounted on axles 43 in each of the three trolleys 42, for example, which can therefore run along the ring. Each trolley .42 carries the shaft 43 at the upper inde and comprises guide surfaces 44 bent in a U-shape; the lower edges of the plates 19 and 20 and the ring segments 21 from below. Each trolley 42 has a downwardly pointing pivot pin 46 which ends at the bottom in a circular end plate 47, whereby a sleeve 48 is rotatably mounted on the pivot pin 46. A. Arm 49 sits on the side of the sleeve 48 and is rotatable with it on the pivot 46 * Dex arm 49 has an extendable £ e ± l 50, which sits slidingly in it

with it in / "the desired extended position ..-- ■ is connected, for example, by a bar 51, which can be nihgesteGkt through the. Part 50 and openings 52 in the jacket of the arm 59 -nih durchgesteGkt. The upper end of the sleeve 48 has teeth 53, which, as soon as the sleeve 48 is moved axially upwards, engage in teeth on the trolley 42. For the perfect ... ' two notches 5: 5 ■ and 56 are provided on the end plate 47, in. ' which depending on the position of the arm. 49 a bead 58 engages on the sleeve 48. When the arm 49 lies radially to the ring, the bead 58 in; the notch 56 (Pig. 5) engages, while the bead 58 in. The notch 55 in the tangential position: engages. The tangential position is shown in dashed lines in ligur 3: At the outer end of the arm part a pivot pin 60 "is provided, on which a conventional, preferably retractable push leg 61 is suspended, which also carries a rock drill 65 pointing downwards parallel to it.

From the corresponding supply points, but they are not are shown, water and compressed air are the hoses or lines 610 and 62, which in a well-protected ^ position are arranged within dew.T-shaped ring 15, supplied. Run from these lines \ 610 and 62 .Hoses 63 and 64 to the rock drill 65 down, to supply them with water and compressed air.

\ The., - Ring: "1-5l is hung in" Arbeitshöiie- ^ ibex the ^ shaft bottom on the cables 24 and on the shaft wall; 10 'anchored by the screw clamps 28. The arms "49, whose links 50 are extended so far that the" f _: pivot pins 60-close- ah: the viewing shaft wall 10; are continuously held in a radially outward-facing position during operation. The various holes are drilled while the trolleys 42 on the ring 15 are in a position corresponding to the hole, and. the push legs 61 are retained on the outboard pivot pins 60. ; '.: "" .- ■. ""

As soon as the pressure of the pressure medium in these tusks \ 61 "takes effect, the ^ sleeve 48 of the arm 49> rises whereby the teeth 53 and 54 come into engagement with one another and the / arm 49> 50 is held with the rock drill hanging on it in the radial working position.

- The fluid pressure also presses the trolley 22 upwards and thereby clamps the surfaces 44 under high friction against the Ring15, whereby lateral movement of the trolley from its selected position can be avoided until the hole to the desired depth drilled is. ; .-. ", - ■■" ■

When the holes are completed, arms 49 . pivoted tangentially to the ring, whereby the beads / 58 engage in notches 55. The thrust legs can get caught on the pivot 60 or you can they. also take off. The cables 24 are then not shown by Lifting equipment taut to support the weight.

of the ring, whereupon the parts 29 of the visual clamps or screw jacks can be withdrawn from the shaft walls. Then the screw jacks -28 can be swiveled tangentially to the ring yer-and the locking pins 41 are. . pushed into the eyelets 38 accordingly. The ring 15 can be freely raised to a safe distance from ..the Sehachtsohle In the already fed point then, as is shown in broken lines in IPigur. 1 The ring remains in this raised but not dismantled state during the blasting and is therefore ready for the next drilling immediately after the blasting process has ended and the loose Ielsbroeken cleared. - "_ ■■ _" \

A lifting of the ring in the already lined part of the shaft is. possible thanks to the swivel arms 49. which can also be used to drill holes in a different direction than in the direction of the surface line of a pyramid. By continuously pushing out and tightening the arms -49, it is possible, for example, to drill all parallel holes in a cylindrical hole. .
