Title: Propulsive mechanism of ground drilling machine and control method therefor
Inventor: YAMAZAKI KAZUYUKI
IPC: E21D9/06
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To avoid a collision with an underground obstacle by accurately surveying a distance to the obstacle with radar for underground exploration during propulsion of a ground drilling machine. SOLUTION: The ground drilling machine having the propulsive mechanism is propelled via a speed reducer 14 by a motor 13 for propulsion while rods 3 are sequentially added to a leading body 5, so as to drill a hole in the ground. In the propulsive mechanism, the speed reducer 14 is taken as a two-stage type having two speed reduction ratios, i.e., high and low speed reduction ratios. Accordingly, when switching to a stage of the high speed reduction ratio takes place, the high speed reduction ratio permits avoidance of an unstable area where revolutions are not stabilized in a state of a low oil flow rate of the motor 13, and prevents occurrence of an unstable state of action with intermittent halts in order to enable stabilization of low-speed propulsion.  When the distance to the underground obstacle is surveyed with the radar 8 for the underground exploration, the distance to the obstacle can be accurately surveyed to enable avoidance of the collision with the obstacle.
