Definitions

  • the invention relates to a device of the type defined in the preamble of claim 1.
  • the invention has for its object to design the device of the type mentioned in such a way that there is an interference-free, low-wear, easy to assemble arrangement, which requires no or only simple components for extension, can therefore be produced at low cost and at Application requires little time.
  • the invention has the advantage that the production trough only needs to be driven out of the working pipe to the front after the production of a perforated section in order to load it in the manner of an excavator shovel with the material detached from the face.
  • the conveyor trough can be brought back into the working tube after loading, backwards through the rear end of the Pulled the work pipe to the starting pit, emptied there and then returned to the work pipe.
  • the conveyor trough thus serves as a means of loading and transportation.
  • the working tube can be pre-pressed with or without a conveying trough in order to prepare for the drilling of a further section of through-hole.
  • the conveyor trough can also be advanced and retracted several times in the working tube, thereby loading the detached material in several successive partial strokes instead of in one go.
  • the entire conveyor can therefore be assembled from a few, extremely robust parts, easily controlled from the starting pit and easily repaired or serviced by moving the conveyor trough back into the starting pit.
  • the device according to the invention for producing underground through-bores contains, for example, a closed, relatively thin-walled and preferably cylindrical working tube 1 made of steel with a rail system 2 fastened to its sides and arranged approximately at half its height, in which a dismantling unit parallel to the axis 4 of the working tube 1 can be moved back and forth in this.
  • the rail system 2 contains, for example, two diametrically opposite guide rails, which are arranged parallel to one another and parallel to the axis 4 of the working tube 1, which are fastened to the inner wall of the working tube 1 and on which a plurality of rollers 5 of a frame 6 of the removal unit roll.
  • a removal head is pivotally mounted, which carries a removal tool 7 at its front end, which preferably consists of a partial cut milling head which can be rotated at high speed and whose outer diameter is substantially smaller, preferably at least half smaller than the inner diameter of the working tube 1.
  • the dismantling unit 3 also contains a gear housing with a gear arranged therein and a drive motor flanged onto it for rotating the dismantling tool 7 about its respective current axis of rotation 8.
  • the dismantling tool 7 is also preferably movable or in such a way parallel to two axes perpendicular to one another and to the axis 4 these axes rotatably or pivotably mounted on the frame 6 that it can be moved as desired within an effective range, the maximum cross section of which corresponds at least to the outer cross section of the working tube 1.
  • This makes it possible to produce a through-bore section bordering the front end of the working tube 1, the cross section of which gradually changes from a cross section initially corresponding to the diameter of the removal tool 7 to, for example, that Outside diameter of the working tube 1 corresponding cross section is increased.
  • the frame 6 is preferably connected to a carriage 10 of the dismantling unit 3, which is also guided in the rail system 2 by means of rollers 11 and is displaceable relative to this and parallel to the axis 4.
  • the carriage 10 is provided with a locking device by means of which it can be immovably locked in the working tube 1.
  • drives which, for example consist of pneumatically or hydraulically operated cylinder / piston units or hydraulic motors.
  • a cylinder / piston arrangement 12 is shown schematically in FIGS. 1 and 2.
  • the working pipe 1 at least one pipe 14 whose inner cross section is smaller than that of the working pipe 1.
  • This tube 14 could, for example, be designed as a formwork tube for a support tube to be produced in the through-bore.
  • the maximum cross section of the mining unit 3 should e.g. in that the mining tool with its axis of rotation 7 is aligned coaxially to the axis 4, can be set to such a small value that the entire mining unit 3 is also retracted through the pipe 14 into a starting pit 15 built at the beginning of the bore 9 and from there can be fed back into the working tube 1.
  • a conveying device 17 is used for the removal of the soil detached from the excavation tool 7 on the working face, which conveyor device has a box-shaped conveyor that can be pushed back and forth in a space 18 below the excavation unit 3 derelement, which is designed as a preferably closed all-round trough 19, which is only provided at its front end facing the current face with a receiving opening 20 (Fig. 4).
  • the conveyor trough 19 lies at least partially on the bottom of the working tube 1, in that its underside has, for example, a shape corresponding to the bottom of the working tube 1, and can therefore be transported back and forth on the bottom of the working tube 1 and parallel to its axis 4.
  • a transport device assigned to it preferably has a reversible drive mechanism which contains at least two cable winches arranged behind it in the direction of the axis 4, each having a drum 21 or 22 and a cable 23 or 24, preferably in the form have sufficiently stable wire ropes.
  • Both drums 21 and 22 are arranged, for example, in the starting pit 15.
  • the free end of the rope 23 wound on the drum 21 runs through the tubes 14 and 1 and is fastened to a holder 25 attached to the rear end of the conveying trough 19.
  • the rope 24 wound on the drum 22 also runs through the tubes 14 and 1, but is then first guided over two vertically superimposed deflecting rollers 26 and 27 which are rotatably mounted at the front end of the working tube 1 and only then at one also at the rear end of the Conveyor trough 19 attached bracket 28 attached. Therefore, when the drum 21 rotates in the direction of an arrow v , the rope 23 is used to pull the conveying trough 19 out of the working pipe 1 and the pipes which may follow it up to the starting pit 15, the rope 24 being simultaneously unwound from the drum 22 .
  • the rope 24 serves to pull the conveying trough 19 out of the starting pit 15 into the working tube 1, the rope 23 being simultaneously unwound from the drum 21.
  • the conveying trough 19 can also be moved back and forth in the working tube 1 by appropriate back and forth rotation of the drums 21 or 22, or optionally pushed forward according to FIGS. 1 and 2 with its front end beyond the front end of the working tube 1 or entirely into the working tube 1 withdrawn will.
  • a pipe 14 with a reduced internal cross-section is arranged behind the working pipe 1, then the bottom of the working pipe 1 expediently has a bevel 29 at the rear end thereof, by means of which the conveying trough 19 adjusts the step between the floors of the working pipe 1 and the pipe 14 can overcome smoothly.
  • the size of the conveyor trough 19 is of course to be selected such that it does not come into contact with the removal unit 3 even when sliding on the slope 29, at least when the latter is in its fully advanced position.
  • the box-shaped conveying trough 19 has two parallel side walls 30, a floor 31 connecting them, arching according to the bottom of the working tube 1, a closed rear wall 32 and a top wall 33, which is expediently designed as a removable or hinged lid.
  • the receiving opening 20 is expediently at least partially surrounded by an edge designed as a cutting edge 34, which facilitates the digging of the conveying trough 19 into the already detached soil located in front of the working pipe 1.
  • schematically indicated wheels 35, rollers or the like are rotatably mounted, which facilitate the sliding of the conveyor trough 19 on the bottom of the working tube 1.
  • the conveyor trough 19 can be guided in a manner similar to the dismantling unit 3 with rails or the like, which are fastened to the inner walls of the working tube 1 and the tubes following this.
  • two brackets 25 arranged near its longitudinal axis and two brackets 28 arranged on each side wall 30 are expediently provided at their rear ends, one each of which Rope 23,24 or a drum 21,22 is assigned.
  • the conveyor trough 19 is transported in both directions with two winches, the sym attack her metrically.
  • the conveying trough 19 is guided in the pipe 14 and in any subsequent pipes of corresponding cross section essentially only with the wheels 35 or the like, the ropes 23, 24 also serving as guide members, while the conveying trough 19 in the working pipe 1 essentially only is guided between the guide walls 37 and slides on the bottom of the working tube.
  • further guides can be provided which automatically align the conveyor trough 19 so that they do not hit the rear ends the guide walls 37 abuts.
  • 5 and 6 also show the position and arrangement of the deflecting rollers 26 and 27, which are provided on both sides of the working tube 1 when using the conveying trough 19 according to FIG. 4 and are rotatably mounted on the struts 36 and the guide walls 37.
  • the ropes 23 and 24 are not shown to simplify the overview.
  • the guide walls 37 run out in a wedge or cone shape towards the front end of the working tube 1. This creates sharp edges 40 on the one hand, so that the pre-pressing of the working tube 1 is not hindered.
  • funnel-like inclined surfaces 41 are formed between the guide walls 37 and the edges 40, which collect the material detached from the through-hole wall and feed it to the area between the two guide walls 37. Therefore, the entire material detached from the working face can be reliably grasped and transported away by advancing or withdrawing the conveying trough 19 even if its width is smaller than the inner cross section of the working tube 1.
  • the working pipe 1 is placed with its front end against the wall to be drilled and, in a known manner (DE-OS 34 23 842), the production of the drilled hole 9 is started.
  • the removal tool 7 is brought into a horizontal position or raised in relation to the axis 4 according to FIG. 1.
  • the conveyor trough 19 is now inserted into the working tube 1 and the required number of cable winches 21, 23 or 22,24 installed, the drums 21,22 are firmly installed in the starting pit.
  • the conveyor trough 19 is now advanced in the working tube 1 until its front end emerges from the front end of the working tube 1 in accordance with the manner shown in FIGS. 1 to 3, thereby moving into the soil detached from the working face digs in and receives this through its receiving opening 20.
  • the conveying trough 19 in the working tube 1 is expediently moved back and forth not only once but several times with short, successive strokes until all detached soil has been taken up.
  • the conveyor trough 19 is retracted and emptied into the starting pit 15 by rotating the drum 21 in the direction of the arrow v .
  • the production of the through-hole 9 is now continued by first working the work tube 1 with the help of pneumatic or hydraulic presses (not shown) or the like, which, for example, act on a ring 42 (FIG. 1) attached to the rear end of the work tube 1 Drilled section advanced, whereupon the steps described are repeated.
  • Pipes which consist of at least two parts separated parallel to the axis 4 and can therefore be placed around the already installed ropes 23, 24 and any other supply lines or the like which may be present. Pipes of this type are known per se (DE-OS 33 40 256).
  • the conveying trough 19 described can, for example, have a width of approximately 600 mm and a height of approximately 400 mm when using a working tube 1 with an outer cross section of 1000 mm, while its length depends on the length of the working tube 1 and the respective conditions. 4 is expediently supported on four wheels 35, although more or fewer wheels 35 can also be provided.
  • the cable winches are preferably powered by hydraulic or electric drives with forces of e.g. 30,000 Newton powered.
  • the conveyor trough 19 is expediently coupled to additional pneumatic or hydraulic drives which give it the movements required to collect the detached soil.
  • the advantages of the conveying trough 19 described are, in particular, that it is structurally simple, low-wear and inexpensive, and can be easily serviced and, if necessary, repaired.
  • the use of chain conveyors, conveyor belts, push rod systems or the like There is no need to constantly change the entire conveyor according to the An to extend the number of tubes pushed towards the working tube 1, since even when using cable winches the length of the cables 23, 24 can be chosen to be as large as the longest bore 9 to be produced corresponds.
  • the use of the conveyor trough 19 also allows the arrangement of a very large receiving opening 20, based on the respective cross section of the working tube 1, which not only enables the removal of the clean end, but also of stones and other bodies with a relatively large cross section present in the ground.
  • the conveyor trough can have a top wall that is firmly connected to the side walls in the front area and can be open at the top in the rear area.
  • the brackets 25 and 28 can be attached to a pivotable flap which forms the rear end of the conveyor trough. In this case, the conveyor trough is simply emptied by lifting it at the front end with the rear flap open. It is also possible to omit the wheels 35 completely and only to allow the conveyor trough to slide in the tubes.
  • the front cutting edge 34 can be designed differently than can be seen from FIGS. 3, 4 and 7.
  • the inlet opening for the soil - starting from the largest cross section of the conveyor trough - is tapered inwards. Therefore, the excavated soil is taken up by cross-section a and then pressed through a narrowed cross-section b and thereby compacted.
  • the cross-sectional shape shown in FIG. 8 can also be provided, in which the inlet opening has the same cross-section c throughout and instead the outer jacket has a conical extension 43 up to the largest cross-section of the conveying trough and presses the excavated soil into the conveying trough without such compaction becomes.
  • Combined cross-sectional shapes are also possible.
