DETAILED PERFORMANCE MACHINE OF A LEVEL SYSTEM OF AT LEAST ONE BLOCKING POSITION OF A ROLLING TEST ON A EXTENSION PROLONG OF A PERFORMANCE BATTERY AND METHOD OF LEAVING AT LEAST ONE BLOCKING POSITION.

摘要

Drilling machine (100) of the single-pass type comprising: - a guide tower (130); - a string of drilling rods (60); - an extension element (1) having an upper end and a lower end, said lower end being coupled with an upper end of the string of drilling rods (60); - a rotary head (15) slidably coupled with the guide tower (130), the rotary head (15) and the extension element (1) being mutually slidable and arranged to couple with each other in an upper end stop position in which the rotary head (15) is coupled with the extension element substantially at the upper end of the extension element (1), and in at least one locking position in which the rotary head (15) is coupled with the extension element (1) at a lower position with respect to the upper end stop position; - a detection system configured to detect the reaching of the at least one locking position by detecting at least the mutual axial position of the extension element (1) and of the rotary head (15).
