Description
i Foreliggende oppfinnelse vedrører en anordning for boring i j fjell og jord hvis bormotor via én rotasjonsoverføring e.l. står i forbindelse med en borstang på hvis ende det er anbragt et slagredskap. i The present invention relates to a device for drilling in rock and soil whose drilling motor via one rotational transmission or the like. is connected to a drill rod at the end of which an impact tool is placed.
Boring utgjør et av de viktigste og mest mangesidige saksområder i bergverk i dagen og under jorden som hjelpemiddel ved utvinning av mineralske råstoffer og ved utsprengning av underjordiske rom (sprenghullboring), ved leting etter og utvinning av olje og gass (dypboring) såvel som for alminnelige geologiske under-søkelser (kjerneboring). I den senere tid har også boring av sjakter og tunneler fått tiltagende betydning (storhullsborihg). Alt etter fjellets styrke blir det ved boring benyttet forskjellige fremgangsmåter, eksempelvis sponavskillende rotasjonsboring, knusende slagboring eller roterende slagboring. Drilling is one of the most important and versatile fields in mining today and underground as an aid in the extraction of mineral raw materials and in the blasting of underground spaces (blast hole drilling), in the search for and extraction of oil and gas (deep drilling) as well as for general geological surveys (core drilling). In recent times, the drilling of shafts and tunnels has also become increasingly important (large-hole drilling). Depending on the strength of the rock, different methods are used when drilling, for example chip-separating rotary drilling, crushing impact drilling or rotary impact drilling.
Ved slagboring benyttes et slagaggregat hvor et stempel blir beveget frem og tilbake og på denne måte overfører opp til 3 000 slag/min. til borstangen. En spesiell anordning på slagaggregatet som er avhengig av kolbebevegelsen, sørger for en dreining av boret. For understøttelse av slagaggregatet og for trykkbelastning tjener enten en trykkluftsylinder eller lavetter med spesiell matningsmotor. På området rotasjonsslag-boring har senkehammerboring vist seg spesielt fordelaktig fordi slagaggregatet arbeider dypt nede i borehullet mens kun dreie-bevegelsen bevirkes utenfor borehullet ved hjelp av en rotasjons-motor. In percussion drilling, a percussion unit is used where a piston is moved back and forth and in this way transmits up to 3,000 strokes/min. to the drill rod. A special device on the impact unit that depends on the piston movement ensures that the drill bit rotates. For supporting the impact unit and for pressure loading, either a compressed air cylinder or a low water with a special feed motor is used. In the area of rotary impact drilling, sinking hammer drilling has proven particularly advantageous because the impact unit works deep down in the borehole while only the turning movement is effected outside the borehole by means of a rotary motor.
Ved senkhammerboring er det kjent å anordne styringen i slag-aggregatets hus. Dette har den ulempe at det ved varierende borebetingelser kun er mulig å styre med høyden av.bortrykket, noe som ved en senkning av bortrykket fører til et betydelig kapasitetsfall og som ved en høyning fører til fare for ødeleggelse av borkronen. Man får de samme ulemper ved senkboring med et hydraulisk slagredskap da dettes styring likeledes befinner seg i slagredskapet. Ved hjelp av en flerromsstang er det riktig-nok mulig å tilføre trykkolje og spylemiddel adskilt, slik at en hydraulisk belastning og dermed en høyere hylse av slagredskapet blir mulig, men det vil ikke være mulig å styre slagredskapets slagantall til de til enhver tid rådende forhold. In the case of hammer drilling, it is known to arrange the control in the housing of the impact unit. This has the disadvantage that with varying drilling conditions it is only possible to control the height of the drilling pressure, which when the drilling pressure is lowered leads to a significant drop in capacity and which, when the drilling pressure is increased, leads to the risk of destroying the drill bit. You get the same disadvantages when countersinking with a hydraulic impact tool, as its control is also located in the impact tool. With the help of a multi-chamber rod, it is indeed possible to supply pressure oil and flushing agent separately, so that a hydraulic load and thus a higher sleeve of the impact tool becomes possible, but it will not be possible to control the impact number of the impact tool to the prevailing conditions at any given time .
På bakgrunn av denne teknikkens stand er det oppfinnelsens hensikt å tilveiebringe en anordning av den innledningsvis nevnte type som i stor grad forbedrer nevnte mangler, slik at denne på enkel måte muliggjør en tilpassning til de til enhver tid rådende borebetihgelser samtidig med at slagredskapets ydelse bibeholdes. On the basis of this state of the art, it is the purpose of the invention to provide a device of the type mentioned at the outset which largely improves the aforementioned shortcomings, so that it enables an adaptation to the drilling conditions prevailing at any time in a simple way, while at the same time that the impact tool's performance is maintained.
Ifølge oppfinnelsen oppnås dette ved at tilførselen av trykkmiddel til slagredskapets slagstempel skjer ved hjelp av en impulsgenerator, som ved hjelp av slanger via rotasjonsover-føringen e.l. og borstangen er tilkoblet såvel oversiden som undersiden av slagstempelet. Impulsgeneratorens frekvens er innstillbar, og med fordel anvendes et hydraulisk trykkmiddel. According to the invention, this is achieved by the supply of pressure medium to the impact tool's impact piston by means of an impulse generator, which by means of hoses via the rotation transmission etc. and the drill rod is connected to both the upper and lower sides of the impact piston. The pulse generator's frequency is adjustable, and a hydraulic pressure medium is advantageously used.
Ved hjelp av denne utformning er det mulig å endre slagverktøyets slagfrekyens ved hjelp av impulsgeneratoren, slik at optimale betingelser til enhver tid kan oppnås ved forskjellige borebetingelser, som f.eks. ved forskjelligartede bergsjikt, leire-inneslutningér i hardt fjell osv. Styring av impulsgeneratorens frekvens kan skje i avhengighet av endringer i borehastigheten boremel osv., enten automatisk eller for hånd. With the help of this design, it is possible to change the impact frequency of the impact tool with the help of the impulse generator, so that optimal conditions can be achieved at all times in different drilling conditions, such as e.g. in the case of different rock layers, clay inclusions in hard rock, etc. Control of the impulse generator's frequency can take place depending on changes in the drilling speed, drilling flour, etc., either automatically or by hand.
Oppfinnelsen skal beskrives nærmere under henvisning til det utførelseséksempel på en boranordning ifølge oppfinnelsen som er vist skjematisk på tegningen. The invention shall be described in more detail with reference to the embodiment of a drilling device according to the invention which is shown schematically in the drawing.
Boremotoren er betegnet med 1 og står via rotasjonsoverføringenThe drill motor is denoted by 1 and is via the rotary transmission
2 i drivforbindelse med borstangen 3. Ved den nedre ende av borstangen 3 er det anbragt et slagverktøy 4 i form av en dyp-hullshammer, hvis slagstempel (ikke vist) innvirker på borkronens 6 skaft 5. 2 in drive connection with the drill rod 3. At the lower end of the drill rod 3, an impact tool 4 in the form of a deep-hole hammer is placed, whose impact piston (not shown) acts on the shaft 5 of the drill bit 6.
Ved rotasjonsoverføringen 2 er det ved hjelp av ledninger 18 tilkoblet en impulsgenerator 9 som drives av en motor 10. Impulsgeneratoren 9 er av vanlig oppbygning, slik at en nærmere beskrivelse av dennes enkeltheter ikke er nødvendig. In the rotational transmission 2, an impulse generator 9 is connected by means of wires 18, which is driven by a motor 10. The impulse generator 9 is of ordinary construction, so that a detailed description of its details is not necessary.
Tilførselsledningene til impulsgeneratoren 9 er betegnet med 11 og 12. Ledningen 13 tjener til tilførsel av et spylemiddel til :rotasjonsoverføringen 2 og via borstangen 3 til borkronen 6; Borstangens 3 utformning er au. en slik type at tilsammen tre ledninger står til rådighet inne i borstangen 3. En av disse ledninger fører spylemiddel, og de to andre ledninger tjener til vekselvis tilførsel og bortføring av hydraulisk trykkmiddel til slagverktøyets 4 slagstempels over- og underside. For dette formål kan det benyttes konsentriske anordnede rør, eller det kan benyttes rørbunter med tre rør. Det er også mulig å benytte en rørbunt bestående av to rør, idet den tredje ledning dannes av det ringformede rom mellom de to rør og den omsluttende bor-stangs innervegg. The supply lines to the impulse generator 9 are denoted by 11 and 12. The line 13 serves to supply a flushing agent to the rotary transmission 2 and via the drill rod 3 to the drill bit 6; The design of the drill rod 3 is au. a type such that a total of three lines are available inside the drill rod 3. One of these lines carries flushing agent, and the other two lines serve to alternately supply and remove hydraulic pressure medium to the upper and lower sides of the impact tool's 4 impact piston. For this purpose, concentrically arranged pipes can be used, or pipe bundles with three pipes can be used. It is also possible to use a tube bundle consisting of two tubes, the third line being formed by the annular space between the two tubes and the inner wall of the surrounding drill rod.
