Description
447 406 2 Uppfinningen kännetecknas av de särdrag som framgår ur närslutna patentkrav och den kommer nu att förklaras närmare med hjälp av bifogade schematiska ritningar, vilka avser utfö- ringsexempel och i vilka fig. 1 visar en första och fig. 2 en andra utföringsform av uppfinningen. The invention is characterized by the features which appear from the appended claims and it will now be explained in more detail with the aid of the accompanying schematic drawings, which refer to exemplary embodiments and in which Fig. 1 shows a first and Fig. 2 a second embodiment of the invention. .
I båda ritningsfigurerna betecknas delar med identisk funktiOn meä identiska hänvisningsbeteckningar.In both drawing figures, parts with identical function are denoted by identical reference numerals.
Enligt fig. 1 är på en oregelbunden marktya 10 i ter- rängen en roterande lasersändare, resp. i allmänhet en strål- ningssändare, 11 uppställd som utsänder en svepande laserstrâle vilken bildar en referensyta 5 med försumbar dimension i verti- kal riktning. Med en bergborrmaskin 20 som har ett underrede 25 på vilket uppbäres en matarbalk 21 skall ett antal hål borras vilka alla sträcker sig till en bottenyta E under markytan 10.According to Fig. 1, on an irregular ground 10 in the terrain is a rotating laser transmitter, resp. generally a radiation transmitter, 11 arranged which emits a sweeping laser beam which forms a reference surface 5 with negligible dimension in the vertical direction. With a rock drilling machine 20 having a base 25 on which a feed beam 21 is supported, a number of holes are to be drilled, all of which extend to a bottom surface E below the ground surface 10.
Längs matarbalken 21 kan en släde 22 med bl.a. ett borraggre- gat förflyttas.Along the feed beam 21, a sledge 22 with e.g. a drilling rig is moved.
På borrmaskinens 20 släde 22 är enligt uppfinningen utom det konventionella borraggregatet en laserdetektor, resp. i all- mänhet en stràlningsmottagare 11A fast monterad. Referensytan 3 är belägen i en sådan nivå, att den ligger under släden 22 och därigenom även under mottagaren 11A när denna befinner sig i sitt högsta läge på matarbommen 21. Detta villkor utgör inte nå- gon otillbörlig inskränkning, eftersom sändaren kan placeras inte endast på godtyckligt ställe inom det område där borrhâ- len skall anläggas, utan även i angränsande terräng, så att det praktiskt taget aldrig kommer att finnas en sådan uppställ- ningsplats för sändaren, att referensytan kommer att ligga under toppen på borrmaskinens matarbalk vid varje borrhål. I undantagsfall kan borrhålen uppdelas i grupper med var sin referensyta på annan nivå, och sändaren flyttas mellan flera uppställningsplatser. Borrmaskinen är utrustad med en elektro- nisk enhet 23 typ dator med åtminstone en minnesfunktion. Till enheten 23 är på släden 22 anordnade konstruktionsdelar inkl.~ laserdetektorn 22 elektriskt anslutna via en flertrådig kabel 22A.According to the invention, on the slide 22 of the drilling machine 20, in addition to the conventional drilling unit, there is a laser detector, resp. generally a radiation receiver 11A permanently mounted. The reference surface 3 is located at such a level that it lies below the carriage 22 and thereby also below the receiver 11A when it is in its highest position on the feed boom 21. This condition does not constitute an undue restriction, since the transmitter can be placed not only on any place in the area where the borehole is to be constructed, but also in adjacent terrain, so that there will practically never be such a stand for the transmitter that the reference surface will be below the top of the drill's feed beam at each borehole. In exceptional cases, the boreholes can be divided into groups, each with its own reference surface on a different level, and the transmitter is moved between several installation locations. The drilling machine is equipped with an electronic device 23 type computer with at least one memory function. Structural parts arranged on the carriage 22, including the laser detector 22, are electrically connected via a multi-wire cable 22A.
Enheten 23 programmeras med djupet Q som är det verti- kala avståndet mellan de båda ytorna 3 och §. Värdet Q sparas i enhetens 23 minne (eventuellt i ett separat minne) för fram- 3 447 406 tagning vid behov. Borrningen påbörjas genom att borrspetsen eller borrkronan 24 på konventionellt sätt börjar att penetre- ra i marken till följd av att släden 22 drivs att glida ned- för matarbommen 21.Slädens 22 rörelse nedför matarbommen 21 in- matas ävenledes i elektronikenheten 23. När den på denna släde fästa laserdetektorn 11A når eller håller på att passera genom referensytan E, vilket sker när borrkronan har nått läget 24', mottas den utsända laserstrâlningen, varigenom sätts igång i enheten 23 en avstängningsfunktion eller ett avstängningsminne och samtidigt genomförs beräkningen av det återstående borrdjupet g i vertikal riktning som måste avverkas för att borrkronan 24 når bottenytan g. Beräkningen görs enligt formeln H = D - L (cos u) _... . . . . . . . . . . . . . . . . . . . . . . . . ..(1), där storleken Q redan har definierats, medan Q är avståndet mellan laserdetektorn 11A och borrkronan 24 (detta avstånd är en oföränderlig maskinparameter och är på förhand inprogrammerad i enheten 23), och Q är vinkeln mellan den aktuella borriktníngen dvs bommens 21 riktning, och den vertikala riktningen 2. Även vinkeln 3 är en storhet som vid varje borrtillfälle eller för flera borrtillfällen gemensamt lätt kan inprogrammeras i enhe- ten 23, eventuellt automatiskt med hjälp av en till matarbommen 21 ansluten lutningsavkännare. Det framtagna värdet E inmatas i nämnda avstängningsminne i enheten 23 med påföljd att borrningen avbryts automatiskt när slädens 22 rörelse nedför matarbommen 21, vilken som redan anförts, även inmatas i elektronikenheten 23, har bragt borrkronan 24 ner till avsett djup (bottenyta §).The unit 23 is programmed with the depth Q which is the vertical distance between the two surfaces 3 and §. The value Q is stored in the unit's 23 memory (possibly in a separate memory) for production if necessary. Drilling is started by the drill bit or drill bit 24 starting to penetrate into the ground in a conventional manner as a result of the carriage 22 being driven to slide down the feed boom 21. The movement of the carriage 22 down the feed boom 21 is also fed into the electronics unit 23. When this slide attached laser detector 11A reaches or is passing through the reference surface E, which occurs when the drill bit has reached the position 24 ', the emitted laser radiation is received, whereby a shut-off function or a shut-off memory is started and at the same time the calculation of the remaining drilling depth is performed vertical direction that must be felled for the drill bit 24 to reach the bottom surface g. The calculation is made according to the formula H = D - L (cos u) _.... . . . . . . . . . . . . . . . . . . . . . . . .. (1), where the magnitude Q has already been defined, while Q is the distance between the laser detector 11A and the drill bit 24 (this distance is an unchanged machine parameter and is pre-programmed in the unit 23), and Q is the angle between the current drilling direction, ie the boom 21 direction, and the vertical direction 2. The angle 3 is also a quantity that can be easily programmed in the unit 23 on each drilling occasion or for several drilling occasions, possibly automatically by means of a inclination sensor connected to the feed boom 21. The generated value E is entered in said shut-off memory in the unit 23 with the consequence that the drilling is stopped automatically when the movement of the carriage 22 down the feed boom 21, which has already been entered in the electronics unit 23, has brought the drill bit 24 down to the intended depth (bottom surface §).
Hos alternativet enligt fig. 2 programmeras enheten 23 likaväl med det vertikala djupet Q, och detta räknas om till ett värde gå enligt formeln BL = _33- 4 " COS O. vilket sparas i enhetens 23 minne. Borrningen påbörjas och när laserdetektorn 11A når eller håller på att passera genom refe- rensytan 3, alstras en signal som i elektronikenheten 23 sätter igång ett avstängningsminne eller en avstängningsfunktion genom_In the alternative of Fig. 2, the unit 23 is programmed as well as the vertical depth Q, and this is converted to a value according to the formula BL = _33- 4 "COS O. which is stored in the memory of the unit 23. The drilling begins and when the laser detector 11A reaches or is passing through the reference surface 3, a signal is generated which in the electronics unit 23 activates a shut-off memory or a shut-off function through
