Abstract

Głowica posiada system zacisku szczęk na żerdzi wiertniczej z wykorzystaniem trzech niezależnie pracujących cylindrów hydraulicznych oraz sprężynowy mechanizm centrowania szczęk (16), składający się z tulei prowadzącej (17), do której za pomocą śrub (18) i dystansów (19) przykręcony jest pierścień (20). Pomiędzy tuleją i pierścieniem umieszczona jest tuleja ślizgowa (21), podparta sprężynami naciskowymi (22), do której przytwierdzone są trzy prowadniki szczęk (23), osadzone w skośnych rowkach prowadzących, wykonanych w każdej ze szczęk System smarowania łożysk (10) głowicy oparty jest o wykorzystanie przecieków oleju hydraulicznego, powstałych podczas zasilania cylindrów hydraulicznych, zaciskających szczęki.The head has a jaw clamping system on the drill rod using three independently working hydraulic cylinders and a spring-loaded jaw centering mechanism (16), consisting of a guide sleeve (17), to which a ring (18) and spacers (19) are screwed twenty). Between the sleeve and the ring there is a sliding sleeve (21), supported by compression springs (22), to which three jaw guides (23) are attached, mounted in oblique guide grooves, made in each of the jaws. The bearing lubrication system (10) of the head is based for the use of hydraulic oil leaks, arising during the supply of hydraulic cylinders clamping the jaws.
