摘要:
The invention provides a tractor for locomoting a drilling apparatus. The tractor includes a retractable body for transporting and pressurizing a drill attached to a front drilling end of the retractable body. The retractable body is longitudinally extended and contracted for length adjustment. A drill stabilizer is attached to a rear trailing end of the retractable body. The drill stabilizer is extended to secure said retractable body during drilling and retracted for allowing movement of the rear trailing end of the retractable body. A position stabilizer is attached to the front drilling end of the retractable body. The position stabilizer is transversely extendable against the sidewalls of the drill hole for periodically stabilizing the retractable body. The position stabilizer retracts for operation of the drill when the drill is stabilized with the drill stabilizer. The tractor travels by extending and retracting the drill stabilizer, extending and retracting the position stabilizer and adjusting length of the retractable body.
