Abstract

Det er tilveiebragt fremgangsmåter og apparat for nøyaktig å bestemme borkronedybde. En kroklast blir samplet med en hastighet på i det minste 4 Hz og blir sammenlignet med en lav terskelverdi for å etablere en kiler inn-tilstand. Det blir fastslått at borestrengen (34) har stoppet å bevege seg når . kroklasten passerte gjennom en hoy dynamisk terskelverdi. På kiler ut-prosedyren blir den identiske hoye terskelverdien brukt, med bevegelse etablert når kroklasten overskrider den hoye terskelverdien. Den hoye dynamiske terskelverdien korresponderer med punktene hvorved borestrengen i virkeligheten stopper og starter bevegelse i kiler inn- og kiler ut-prose- dyrene. Apparatet som er tilveiebragt er et trekkverkskoder- montasjesett som kan anordnes på en hjelpebremsseksjon (70) til trekkverket (22) eller den roterende tettende luftkopler (76) til en trekkverksclutch. Et splittringtannhjul (80) passer rundt og er festet til den roterende sylinderen til den roterende tettende luftkopleren. Splittringtannhjulet (80) er del av en trinse som har et annet tannhjul (87) og et drivbelte (85), slik at rotasjon av trommelen og den roterende tettende luftkoplersylinderen blir overfort til en aksel til en koder (90) som er koplet til det andre tannhjulet. Koderen følger derved rotasjonsbevegelsen til trekkverkstroromelen. Det er også anordnet en andre koder som er del av en kalibrator (100) som ved ønskelige tidspunkter via en kalibratortråd nøyaktig måler lokaliseringen av vandreblokken (28) i forhold til en kjent vertikal lokalisering. Den første og andre koderavlesning blir sammenlignet kontinuerlig og blir brukt til å tilveiebringe utmerkede kalibreringer mellom trommelrotasjonen og vandreblokk- bevegelsen.
