Abstract

Anordning ved boretårn (1) med boremaskin (2) som er bevegbar i forhold til boretårnet (1) under boring, ved innskjøting av og ved opphenting av borestrengelementer (3; 2 l). Boretårnet omfatter minst tre innbyrdes atskilte, parallelle, vertikale søyler (4 - 7) som nederst er forbundet med et boregulv (8) eller fundament (9) og øverst i et felles rammeverk (10). Boremaskinen (2) er montert i en bæreramme (11) som har trekantet, rektangulær eller firkantet utformning. Bærerammens hjørner har føringer (12 - 16) for glidbart inngrep med en respektiv søyle (4 - 7), og et par av teleskopiske aktuatorer (17; 18) er anordnet for styrbart for å føre bærerammen (11) langs søylene (4 - 7) til ønsket nivå.Device at drill tower (1) with drill (2) movable relative to drill tower (1) during drilling, insertion and retrieval of drill string elements (3; 2 l). The drill tower comprises at least three spaced, parallel, vertical columns (4 - 7) connected at the bottom to a drill floor (8) or foundation (9) and at the top of a common framework (10). The drill (2) is mounted in a support frame (11) having a triangular, rectangular or square design. The corners of the support frame have guides (12 - 16) for slidable engagement with a respective column (4 - 7), and a pair of telescopic actuators (17; 18) are arranged for controllable to guide the support frame (11) along the columns (4 - 7). ) to the desired level.
