Definitions

  • the invention relates to a drilling device, in particular for blasting hole drilling, with a mount for the feed and the pulling of the drill rod formed from individual drill rods, a feed system, a pressure-actuated drive for the drill rod, a flushing head which can be moved on the mount with and separate from the drill rod, and a hydraulically actuated in-hole hammer arranged at the front end of the drill pipe.
  • Drilling devices of the aforementioned type have long been known and are used in particular in mining and tunneling as well as in the stone and earth industry.
  • the advantage of the in-hole hammers is that their strikes take place directly on their chisels and thus energy losses in the drill pipe are avoided compared to the version in which the hammers are arranged behind the drill pipe.
  • the working air of the hammers serves to discharge the cuttings.
  • This is not possible with hydraulically driven hammers, so that three lines for them in the drill pipe must be available, namely one for the hydraulic feed to the hammer, one for the hydraulic return from the hammer and one for compressed air to blow out the cuttings.
  • This design has the disadvantage that the hydraulic system has to be switched off when changing the boring bar and that losses in hydraulic oil have to be accepted when the boring bars are disconnected and (re) assembled and contamination cannot be avoided.
  • the object of the invention is to provide, while avoiding the aforementioned disadvantages, a drilling device of the type mentioned at the outset, which, when using a hydraulically actuated in-hole hammer arranged at the front end of the drill pipe, enables simple and quick rod change .
  • this is achieved in that the pressure-actuated drive of the drill pipe transmits a reciprocating swiveling movement thereon.
  • a reciprocating swiveling movement In deviation from the previously used rotary drive, one is now used for a reciprocating pivoting movement. This makes it possible to between the required hoses in the annulus To accommodate drill pipe and borehole wall with the result that they do not have to be interrupted when changing the pipe.
  • the swivel range of the drill pipe is preferably limited to a swivel angle between 180 and 360 degrees.
  • a swivel motor with gear is advantageously used as the drive.
  • the torque transmission from the drive to the drill pipe takes place by positive locking, preferably by profiling the drill rods, or by frictional locking, preferably by means of a clamping device.
  • the drive for the drill rod which is pressurized with pressure medium, is located on a carriage which can be moved on the carriage of the drilling device.
  • the carriage can be moved with the drive by means of the feed chain via the flushing head and / or via separate drives thereof.
  • the boring bars have two longitudinal channels open to the outside, which are used to hold the hoses for the supply and discharge of the pressure oil for the in-hole hammer.
  • the hydraulic hoses are thus within the circumference of the boring bars and do not protrude above them, so that they are largely secured against wear.
  • the purge air is supplied directly through the hollow boring bars.
  • the longitudinal channels of the boring bars have a smaller width on their outer areas than in their inner areas, so that the hoses can be expanded again inside the longitudinal channels after being pressed in over the narrowed areas, taking advantage of the inherent elasticity, and are thus held securely in these.
  • the boring bars have a channel open to the outside for receiving an air hose for the purge air.
  • the flushing head is also, at least in its lower area, with longitudinal channels for receiving hydraulic hoses and / or the air hose.
  • the boring bars are provided at their ends with mutually adapted fittings for the rotationally fixed connection of the boring bars and for the aligned connection of the longitudinal channels thereof, so that it is ensured that not only a perfect transmission of the torque takes place during the reciprocating pivoting movement, but also during one Connection of the individual boring bars with each other whose longitudinal channels are always in alignment, otherwise assembly is not possible.
  • the shaped pieces consist of projecting bolts provided on one end of the boring bars and of recesses provided at their other ends, which are adapted to one another in their shapes.
  • the ends of mutually connected boring bars are coupled to one another by means of spring-loaded dowel pins so that they can be easily and quickly detached from one another or connected to one another.
  • the boring bars can be equipped with blown air lines, one end of which is located within the boring bar and the other ends of which project freely from the boring bar in which the spring-loaded dowel pins are attached, which pass through the blowing air lines transversely to their longitudinal axes and engage in their locking positions in bores in the walls of adjacent boring bars.
  • a hose threading and unthreading device is provided on the carriage in front of the connecting area of two boring bars to be connected, by means of which the hoses are pressed into the longitudinal channels of the newly inserted boring bar when changing the rod or are pressed out of the latter when the rod is pulled.
  • the hoses are then threaded into the longitudinal channels of the projecting drill rod in accordance with the feed or are threaded out when the drill pipe is pulled.
  • the hose threading and unthreading device is attached to the slide of the drive for the drill pipe and directly or indirectly coupled to the drive member thereof, so that this device also carries out the pivoting movement transmitted to the drill pipe.
  • the hose threading and unthreading device has a threading and a threading member for each hose.
  • the threading and threading members consist of guide rollers and / or sliding guides.
  • the threading and threading elements for each hose are arranged at a distance from one another such that the associated hose can be passed around the threading element facing away from the drill pipe and between threading element and the threading element assigned to the drill pipe.
  • the threading and threading members can be folded away from the area of the drill pipe.
  • the drill itself is equipped with a prestressed drum for the hydraulic hoses and, if necessary, an air hose, so that these are always automatically kept at their required length.
  • the length of the hoses is dimensioned such that it is completely sufficient for the depth of the boreholes to be produced.
  • the longitudinal channels 2 have a smaller width at their outer regions 3 than in their inner regions.
  • the hydraulic hoses 4, 5, one of which is the inlet and the other the return, are inserted into the longitudinal channels 2 for the pressure oil of the in-hole hammer located at the front end of the drill pipe.
  • the boring bar 1 itself is hollow, so that the required purge air for the cuttings is passed through the boring bar.
  • the hoses 4, 5 are held securely in these, since they are pressed into the longitudinal channels 2 by being pressed together.
  • the hoses protected in this way can easily carry out the reciprocating pivoting movement of the drill pipe, for example by a pivoting angle between 180 and 360 degrees, without being subject to wear.
  • the boring bars 1 are made of solid material. Since the flushing air for the in-hole hammer cannot be blown through the interior of the boring bars 1 in this embodiment, the boring bars 1 are equipped with blown air lines 6. The one ends 7 of the blown air lines 6 are located within the boring bars 1, while the other ends 8 project freely therefrom. There are spring-loaded in the freely projecting ends 8 Dowel pins 9 which pass through the blown air line 6 transversely to their longitudinal axes and engage in their locking positions (FIG. 3) in bores 10 in the walls of adjacent boring bars 1. The spring-loaded dowel pins 9 make it quick and easy to change the boring bars 1 when advancing or pulling the drill pipe.
  • the boring bars 1 are provided at their ends with mutually adapted shaped pieces for the rotationally fixed connection of the boring bars to one another and for the aligned connection of the longitudinal channels 2 of the same.
  • the shaped pieces consist of projecting bolts 11 provided on one end of the boring bars 1 and of recesses 12 provided on their other ends.
  • the projecting bolts 11 and the recesses 12 associated therewith are matched to one another in terms of their shapes so that they engage in a form-fitting manner.
  • the boring bars 1 can be provided on their outer sides with profiles 13 running in their longitudinal directions, which serve to transmit torque to the drill pipe.
  • the pressure medium-actuated drive for the reciprocating pivoting movement of the drill rod formed from the individual boring bars 1 is designated by 15.
  • a swivel motor is used, which is equipped with a gear 16, the drive pinion 17 of which transfers the reciprocating swiveling movement to the respective above boring bar 1.
  • the drive 15 with its gear 16 for the drill pipe is located on a carriage 18 which can be moved on the carriage 14.
  • the carriage 18 is moved on the carriage 14 and the flushing head 19 either by advancing the flushing head 19 or by separate drives of the same.
  • the hose threading and threading device 20 is attached to the carriage 18.
  • the hose threading and unthreading device 20 is connected to the drive pinion 17 of the gear 16 of the drive 15 for the drill pipe, so that this carries out the reciprocating pivoting movement of the drill pipe.
  • the hose threading and threading device 20 has for each hydraulic hose 4, 5 a threading element 21 and a threading element 22.
  • the threading and unthreading members 21, 22 are shown as sliding guides and in the lower position of the carriage 18, as can be seen in FIG. 5, as guide rollers.
  • the threading members 21 and the threading members 22 are arranged at a distance from one another such that the associated hydraulic hose 4, 5 is guided around the threading member 22 facing away from the drill string and can be passed between the threading member 22 and the threading member 21.
  • the design of the hose threading and threading device 20 is such that the threading and threading elements 21, 22 are in the upper holding position of the slide 8 with the drive 15 in the region of the flushing head, the threading elements 22 still projecting therefrom.
  • the hydraulic hoses 4, 5 are guided via deflection rollers 23 to a prestressed drum 24.
  • the boring bar 1 newly inserted from a boring bar magazine (not shown further) can be drilled in the conventional manner.
  • the feed takes place, for example, via the chain feed of the flushing head 19.
  • a new boring bar 1 from a boring bar magazine can be inserted.
  • the drill pipe located in the borehole is held in a conventional manner by the holding head 25, whereupon the slide 18 with the drive 15 can move back into its upper position shown in FIG. 4.
  • the hydraulic hoses 4, 5 are pressed into the longitudinal channels 2 of the newly inserted boring bar 1 via the threading members 21.
  • the newly inserted boring bar 1 can then be drilled out, as can be seen from FIG.
