Abstract
Zariadenie je určené na riadenie technologie vřtania korun na základe indikácie podielu okamžitej rýchlosti vřtania a mernej objemovej práce rozpojovania. Měrná objemová práca rozpojovania je priamo úmerná intenzitě opotrebovania nástroja. Maximum uvedeného podielu implicitně určuje přítlak a otáčky pre ekonomicky najracionálnejší spůsoh vřtania.The device is designed to control the technology of drilling crowns based on the indication of the ratio of the instantaneous drilling speed and the specific volumetric work of separation. The specific volumetric work of separation is directly proportional to the intensity of tool wear. The maximum of the above ratio implicitly determines the pressure and speed for the most economically rational drilling method.

Vynález sa týká zariadenia na indikáciu mernej okamžitej rýchlosti vřtania pri rotačnom vrtaní na principe spojitého delenia dvoch elektrických signálov snímaných v priebehu vrtného· procesu pri vrtacích zariadeniach.BACKGROUND OF THE INVENTION The present invention relates to a device for indicating the specific instantaneous drilling speed of a rotary drilling on the principle of continuous separation of two electrical signals sensed during a drilling process in drilling equipment.
Doteraz pri vrtaní hornin sa používajú zariadenia, ktoré dovolujú indikovat definované veličiny umožňujúce riadiť proces vřtania podlá různých technických kritérií. Jedným. zo spůsobu riadenia procesu vřtania je zariadenie, na maximalizáciu podielu druhej mocniny okamžitej rýchlosti vřtania a absolutnej hodnoty derivácie okamžitej rýchlosti vřtania podlá času umožňuje maximalizovat životnost nástroja.So far, rock drilling devices have been used which allow the indication of defined quantities enabling the drilling process to be controlled according to various technical criteria. One. From the method of controlling the drilling process, a device is used to maximize the life ratio of the square of the instantaneous drilling rate and the absolute value of the derivative of the instantaneous drilling rate over time.
Nevýhoda tohto spůsobu a zariadenia je v tom, že spolahlivo může pracovat len v kvázi hamogénnych horninách a riadenie procesu pomocou tejto indikcvanej veličiny je nepružné, pretože stanovenie hodnoty derivácie okamžitej rýchlosti vřtania vyžaduje aplikáciu konštantného režimu vřtania. Dalším z takýchto zariadení je zapojenie indikátora objemového rozpojovania hornin pri vrtaní chráněného AO č. 185 857, ktorý indikuje podiel výkonu a okamžitej rýchlosti vřtania pri rozpojovaní hornin s různými prítlakmi a otáčkami. Nevýhoda tohto zariadenia a následného riadenia procesu minimalizáciou uvedeného podielu je v tom, že minimálna hodnota tejto veličiny je len čiastkovým ekonomickým kritériom, ktoré zohladňuje tiež maximálnu životnost nástroja.The disadvantage of this method and apparatus is that it can reliably operate only in quasi-hamogenic rocks, and the process control by this indicated quantity is inflexible, because determining the value of the instantaneous drilling rate requires the application of a constant drilling mode. Another such device is the engagement of the rock disintegration indicator when drilling protected AO No. 185 857, which indicates the power output and the instantaneous drilling speed when disintegrating rocks at different pressures and speeds. The disadvantage of this device and the subsequent control of the process by minimizing said proportion is that the minimum value of this quantity is only a partial economic criterion which also takes into account the maximum tool life.
Nevýhody doposial používaných zariadení odstráňuje zariadenie na indikáciu mernej okamžitej rýchlosti vřtania, ktoré je predmetom vynálezu. Podstata vynálezu spočívá v tom, že zariadenie pozostáva z analógovej funkčnej deličky, ktorá je na jednom vstupe připojená na převodník okamžitej rýchlosti vřtania, na druhom vstupe je připojená na merač mernej objemovej práce rozpojovania a na výstupe je zapojený napáťový indikátor. Výsledkom analogového· delenia je elektrický signál mernej okamžitej rýchlosti vřtania, ktorý vyjadřuje hodnotu okamžitej rýchlosti vřtania pripadajúcu na jednotku mernej objemovej práce rozpojovania. Nakolko měrná objemová práca rozpojovania je priamo· úměrná intenzitě opotrebovania nástroja, potom měrná okamžitá rychlost vřtania pri rozpojovaní jedného typu horniny charakterizuje okamžitá rýchlosť vřtania pripadajúcu na jednotku intenzity opotrebovania nástroja, ktorá sa výrazné tmění v diapazóne používaných hodnot přítlaku a otáčok pri vrtaní. To znamená, že maximálně hodnota takto definovanej mernej okamžitej rychlosti vřtania implicitně určuje přítlak a otáčky pre ekonomicky najracionálinejší sposob vřtania.The disadvantages of the devices used up to now are eliminated by the device for indicating the specific instantaneous drilling rate of the invention. SUMMARY OF THE INVENTION The device consists of an analog function divider which is connected to an instantaneous drilling speed transducer on one input, connected to a specific disconnection meter on the other and a voltage indicator is connected to the output. The result of the analog splitting is an electrical instantaneous drilling rate electrical signal that expresses the instantaneous drilling rate value per unit of the specific decoupling volume work. Since the discrete volume work is directly proportional to the wear rate of the tool, then the specific instantaneous drilling rate when disengaging one type of rock characterizes the instantaneous drilling rate per unit of tool wear rate, which is markedly darkened in the diapazon of drilling pressure and speed used. That is, the maximum value of the specific instantaneous drilling speed thus defined implicitly determines downforce and speed for the most economically rational drilling method.

The converter 1 transforms the instantaneous drilling speed into a voltage signal v (t) which is applied to the first input of the analog splitter 3. As an example of divider 3, a divider with quadrator 4 and amplifiers 5, 6 and 7 is shown. At the output of amplifier 7, a proportion of voltage signals is obtained in (t) and w (ie. 3 leads to the voltage indicator 8.
