Control equipment for controlling drill rod

摘要

Control equipment for guiding a drill rod. The control equipment including a frame and two guide jaws provided with guide surfaces and mounted movably in relation to the frame. The drill rod is set between the guide jaws during drilling. Actuators move the guide jaws in relation to the drill rod. Synchronization means are coupled between the guide jaws, such that the guide jaws always move in opposite directions to one another and at the same speed. A detector detects that the guide surfaces of the guide jaws are in contact with the drill rod.

1. Control equipment for guiding a drill rod, the control equipment comprising:
a frame; two guide jaws, each provided with guide surfaces and mounted to be linearly movable in relation to the frame the drill rod being set between the guide jaws during drilling; actuators for moving the guide jaws transversely to an axis of the drill rod for moving them away from one another, and correspondingly, towards one another for guiding the drill rod; a detector for detecting that the guide surfaces of the guide jaws are in contact with the drill rod; and synchronization means coupled between the guide jaws so that the guide jaws always move in opposite directions to one another and at the same speed.
