Abstract

본 발명에 따른 굴착 장치는, 일 단으로부터 타 단을 향해 점진적으로 커지는 폭을 가지고 타 단에서 외주면에 고정홀을 가지는 하부 아암; 하부 아암의 타 단 상에 위치되어 디스크 형상으로 이루어지고 하부 아암에 회전 고정되는 회전 암대; 회전 암대 상에 위치되어 회전 암대에 고정되고 회전 암대 상에서 외주면에 안내홀을 가지는 상부 아암; 하부 아암과 회전 암대와 상부 아암에 의해 둘러싸이고 하부 아암의 고정홀과 상부 아암의 안내홀을 통해 외부에 노출되는 센터 조인트; 및 상부 아암의 안내홀을 통해 센터 조인트에 삽입되거나 센터 조인트로부터 분리되는 슬립 링을 포함한다.
