Description

Oppfinnelsens område. Field of the invention.

Den foreliggende oppfinnelse vedrører en anordning for løsgjøring av borestenger, enten enkeltstenger eller sammenkoblede sjøtestenger. The present invention relates to a device for releasing drill rods, either single rods or connected sea test rods.

Teknikkens stilling. The position of the technique.

I forbindelse med boring av sprengningshull i bakken, i fjell eller i tunneler, støter man ofte på det problem at borestangen eller borestengene som kan være sammenskrudd til en borestreng, kiler seg fast i borehullet og således er vanskelig å få opp av borehullet. Man har i den forbindelse prøvd å fylle dieselolje i borehullet for derved å kunne løse opp massen som holder borestengene tilbake, hvoretter man søker å trekke opp borestengene ved hjelp av boremaskinens hammer, dvs. ved hjelp av wirer eller kjeder som beveger hammeren under vanlige bore-operasjoner. In connection with drilling blast holes in the ground, in mountains or in tunnels, one often encounters the problem that the drill rod or drill rods, which may be screwed together to form a drill string, get wedged in the drill hole and are thus difficult to get out of the drill hole. In this connection, one has tried to fill diesel oil into the borehole in order to thereby be able to dissolve the mass that holds the drill rods back, after which one tries to pull up the drill rods with the help of the drilling machine's hammer, i.e. with the help of wires or chains that move the hammer during normal drilling operations.

Videre har man for opptrekking av fastkilede borestenger benyttet jekker, med det resultat at borestengene er blitt slitt av, og borehullet således redusert hva angår dybde for den tilsiktede sprengvirkning. Dessuten går det tapt borestenger som kunne vært brukt på nytt. Furthermore, jacks have been used to pull up wedged drill rods, with the result that the drill rods have been worn off, and the drill hole thus reduced in terms of depth for the intended blasting effect. In addition, drill rods are lost that could have been reused.

Omtale av oppfinnelsen. Mention of the invention.

Til grunn for den foreliggende oppfinnelse ligger den oppgave å råde bot på de ovennevnte problemer, og ved en anordning av den innledningsvis angitte art, løses dette ifølge oppfinnelsen ved at anordningen omfatter en hjelpeborestang eller borestanglignende hjelpestang som ved den ene ende er innrettet til å kobles til en borestang som skal løsgjøres, og som ved den andre ende bærer et fastgjort hylselformede organ som tjener til over-føring av kraften fra en separat kraftpåvirket borestang i hovedsakelig motsatt retning av boreretningen for den eller de borestenger som skal løsgjøres. The present invention is based on the task of remedying the above-mentioned problems, and in the case of a device of the type indicated at the outset, this is solved according to the invention by the device comprising an auxiliary drill rod or drill rod-like auxiliary rod which is arranged at one end to be connected to a drill rod to be loosened, and which at the other end carries a fixed sleeve-shaped member which serves to transfer the force from a separate force-affected drill rod in a direction essentially opposite to the drilling direction for the drill rod(s) to be loosened.

Den separate borestang kan da være tilkoblet hammeren på en passende boremaskin, og ved hjelp av hammervirkning kan den fastkilte borestang eller de fastkilte borestenger hamres ut av sitt feste, idet hylsen virker som mothold for den separate borestang. The separate drill rod can then be connected to the hammer of a suitable drilling machine, and with the help of hammer action, the wedged drill rod or the wedged drill rods can be hammered out of their attachment, as the sleeve acts as a counterweight for the separate drill rod.

Hensiktsmessig kan hylsen utgjøres av et rørstykke med en åpen ende og en motsatt lukket ende, idet rørstykket er fastgjort ved den ene ende av hjelpeborestangen under en liten vinkel i forhold til lengdeaksen for den eller de borestenger som skal løsgjøres. Appropriately, the sleeve can consist of a pipe piece with an open end and an opposite closed end, the pipe piece being attached to one end of the auxiliary drill rod at a small angle in relation to the longitudinal axis of the drill rod(s) to be detached.

En slik hjelpestang med hylse kan tilpasses alle typer boremaskiner, fortrinnsvis slike som kan snus opp ned, dvs. maskiner hvor hammeren kan snus til boring i bakke eller fjellvegg, innbefattet i retning oppover eller til siden. Such an auxiliary rod with a sleeve can be adapted to all types of drilling machines, preferably those that can be turned upside down, i.e. machines where the hammer can be turned for drilling in ground or rock wall, including in an upward or sideways direction.

Ytterligere omtale av oppfinnelsen vil fremgå av den medfølgende tegning og den ytterligere beskrivelse, samt av de vedføyde patentkrav. Further mention of the invention will appear from the accompanying drawing and the further description, as well as from the appended patent claims.

Kort omtale av teqninqsfiquren. Brief mention of the teqninqsfiquren.

Figur 1 er et skjematisk riss delvis i snitt som viser en utførelsesform for anordningen ifølge oppfinnelsen. Figure 1 is a schematic diagram, partially in section, showing an embodiment of the device according to the invention.

Beskrivelse av utførelsesformer. Description of embodiments.

På den vedføyde figur 1 som viser et utførelseseksempel for anordningen ifølge oppfinnelsen, er det således vist en anordning for løsgjøring av borestenger, enten enkelt- In the attached Figure 1, which shows an embodiment of the device according to the invention, a device for loosening drill rods is thus shown, either individually

stenger eller sammenkoblede sjøtestenger. rods or connected sea test rods.

Av figur 1 fremgår det at anordningen ifølge oppfinnelsen omfatter en ved den ene ende av en hjelpeborestang 1 eller borestanglignende hjelpestang fastgjort hylse 2 som tjener til innføring av en separat kraftpåvirket borestang 3 i hovedsakelig motsatt retning av boreretningen for den eller de borestenger 4 som skal løsgjøres. From Figure 1, it appears that the device according to the invention comprises a sleeve 2 attached to one end of an auxiliary drill rod 1 or drill rod-like auxiliary rod, which serves to insert a separate force-affected drill rod 3 in a direction essentially opposite to the drilling direction for the drill rod(s) 4 to be loosened .

Hensiktsmessig utgjøres hylsen 2 av et rørstykke med en åpen ende 2a og en motsatt lukket ende 2b, samtidig som rørstykket 2 er fastgjort ved den ene ende 1 a av hjelpeborestangen 1 under en liten vinkel a i forhold til lengderetningen for den eller de borestenger 4 som skal løsgjøres. Suitably, the sleeve 2 consists of a piece of pipe with an open end 2a and an opposite closed end 2b, while the piece of pipe 2 is attached to one end 1a of the auxiliary drill rod 1 at a small angle a in relation to the longitudinal direction of the drill rod(s) 4 to be be released.

Hensiktsmessig kan hylsen ha en lengde av 140 cm, mens den er tilpasset en hjelpeborestang på ca. 3 m, hvilken sistnevnte lengde svarer til en standardlengde for en borestang. Appropriately, the sleeve can have a length of 140 cm, while it is adapted to an auxiliary drill rod of approx. 3 m, which latter length corresponds to a standard length for a drill rod.

Det skal forstås at hjelpeborestangen 1 med hylsen 2 kan fastgjøres på det fastkilte bor 4 ved hjelp av håndkraft, og etter at hjelpeborestangen 1 med hylse 2 er fastskrudd til stangen 4, kan den separate kraftpåvirkede borestang 3 føres inn i hylsen 2, og under påvirkning av et hammer-organ 5 på en passende boremaksin, kan slagvirkningen fra det separate bor 3 mot bunnen 2b av hylsen 2 drive det fastkilte bor 4 ut av bakken. It should be understood that the auxiliary drill rod 1 with the sleeve 2 can be attached to the wedged drill 4 by hand force, and after the auxiliary drill rod 1 with sleeve 2 is screwed to the rod 4, the separate force-affected drill rod 3 can be fed into the sleeve 2, and under the influence of a hammer member 5 on a suitable drilling machine, the impact of the separate bit 3 against the bottom 2b of the sleeve 2 can drive the wedged bit 4 out of the ground.

Det skal forstås at denne anordning kan tilpasses alle typer boremaskiner, fortrinnsvis slike som kan få sitt drivorgan snudd opp ned, eller fortrinnsvis snus til alle retninger. Hammerorganet kan da snus til den retning som måtte passe, det være seg relatert til boring i bakken eller i fjellvegger i alle retninger. It should be understood that this device can be adapted to all types of drilling machines, preferably those that can have their drive member turned upside down, or preferably turned in all directions. The hammer body can then be turned to any direction that suits, be it related to drilling in the ground or in rock walls in all directions.
