도면중 미설명 부호 26은 삐뚤어진 천공홀(22)의 내부에 형성된 돌출부위를 나타낸 것이다.In the figure, reference numeral 26 denotes a protruding portion formed in the crooked hole 22.

이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도2 내지 도8에 도시된 바와 같이 지표면(20)에 형성된 천공홀(22)의 중심이 수직을 이루지 못하고 삐뚤어진 경우 본 발명의 장치를 천공홀(22) 안으로 집어넣어서 파워해머(100)의 해머비트(102)가 천공홀(22) 내부의 돌출부위(26)와 동일한 높이를 이루도록 위치시킨 다음 유압실린더(40)를 작동하여 피스톤로드(42)를 돌출시키게 되면, 피스톤로드(42)의 선단에 힌지핀(54)으로 결합되어 있던 벽면지지판(50)이 천공홀(22)의 내측 벽면(24)에 밀착된다.As shown in FIGS. 2 to 8, when the center of the drilled hole 22 formed in the ground surface 20 is not vertical and is skewed, the device of the present invention is inserted into the drilled hole 22 to power the hammer 100. When the hammer bit 102 is positioned to have the same height as the protruding portion 26 in the drilling hole 22 and then operates the hydraulic cylinder 40 to protrude the piston rod 42, the piston rod 42 The wall support plate 50, which is coupled to the tip of the hinge pin 54, is in close contact with the inner wall surface 24 of the drilling hole 22.

이때 피스톤로드(42)와 벽면지지판(50)이 힌지핀(54)에 의해 회동가능하게 결합되어 있기 때문에 벽면지지판(50)은 천공홀(22)의 내측 벽면(24)에 좀 더 균일 한 압력으로 밀착되며, 예를 들어서 벽면지지판(50)이 사방으로 4개 설치된 경우 4개의 벽면지지판(50)에 의해 유압실린더(40)의 하측에 결합되어 있는 원반형행거(30)가 천공홀(22)의 중심에 위치된다.At this time, since the piston rod 42 and the wall support plate 50 are rotatably coupled by the hinge pin 54, the wall support plate 50 is more uniformly pressured on the inner wall surface 24 of the drilling hole 22. When the wall support plate 50 is installed in four directions, for example, the disk-shaped hanger 30 coupled to the lower side of the hydraulic cylinder 40 by the four wall support plates 50 is drilled through the holes 22. Is located in the center of.

이때 파워해머(100)로 유압 또는 공압과 같은 작동유체를 공급하게 되면, 파워해머(100)가 천공홀(22)의 내측 돌출부위(26)를 타격하여 부수게 되며, 이와 동시에 상판(46)에 설치된 유압모터(80)를 저속으로 구동하게 되면, 유압모터(80)로부터 발생된 회전력이 모터축(82)과 커플링(86)을 통해 구동축(84)으로 전달되면서 구동축(84)의 하단에 연결되어 있는 피니언(74)이 회전되고, 이 피니언(74)과 맞물려 있는 스윙기어(70)가 회전된다.At this time, when supplying a working fluid such as hydraulic pressure or pneumatic to the power hammer 100, the power hammer 100 hits the inner protruding portion 26 of the drilling hole 22, and at the same time, the top plate 46 When driving the hydraulic motor 80 installed in the low speed, the rotational force generated from the hydraulic motor 80 is transmitted to the drive shaft 84 through the motor shaft 82 and the coupling 86, the lower end of the drive shaft 84 The pinion 74 connected to is rotated, and the swing gear 70 engaged with the pinion 74 is rotated.

이와 동시에 스윙기어(70)의 저면에 결합되어 있던 하부회전통(90)이 스윙기어(70)와 함께 회전되면서 하부회전통(90) 속에 설치되어 있던 파워해머(100)를 비롯하여 해머이송실린더(110)(112) 등이 천천히 회전된다.At the same time, the lower rotary cylinder 90 coupled to the bottom of the swing gear 70 is rotated together with the swing gear 70 and the hammer transfer cylinder including the power hammer 100 installed in the lower rotary cylinder 90 ( 110, 112, etc. are rotated slowly.

이와 같이 하부회전통(90)의 회전에 의해 구동중인 파워해머(100)가 소정각도로 왕복운동되면서 천공홀(22) 내부의 돌출부위(26)를 제거하게 된다.As such, the power hammer 100 being driven by the rotation of the lower rotating cylinder 90 reciprocates at a predetermined angle to remove the protruding portion 26 inside the drilling hole 22.

즉, 하부회전통(90)이 회전될 때 하부회전통(90)에 설치된 스위치도그(130)가 원반형행거(30)에 소정각도를 이루도록 설치된 리미트스위치(L1)(L2)에 의해 검출될 때마다 유압모터(80)가 콘트롤러(도시 않됨)와 방향전환전자밸브(도시 않됨)에 의해 역회전되면서 하부회전통(90)과 파워해머(100)가 설정된 각도로 왕복운동된다.That is, when the lower rotary cylinder 90 is rotated when the switch dog 130 installed in the lower rotary cylinder 90 is detected by the limit switch (L1) (L2) provided to form a predetermined angle to the disk-shaped hanger (30) Each time the hydraulic motor 80 is reversely rotated by a controller (not shown) and a direction switching solenoid valve (not shown), the lower rotary cylinder 90 and the power hammer 100 are reciprocated at a set angle.

한편, 하부회전통(90)의 내부 바닥면에 설치된 실린더집(120)(122)에 고정된 해머이송실린더(110)(112)로 유압이 공급되어 해머이송실린더(110)(112)의 피스톤로드가 전진 또는 후진되면, 파워해머(100)는 해머가이드(104)에 의해 직선안내되면서 전진 또는 후진된다.Meanwhile, the hydraulic pressure is supplied to the hammer transfer cylinders 110 and 112 fixed to the cylinder houses 120 and 122 installed on the inner bottom surface of the lower rotary cylinder 90 so that the pistons of the hammer transfer cylinders 110 and 112 are provided. When the rod is moved forward or backward, the power hammer 100 is guided linearly by the hammer guide 104 to move forward or backward.

이때 해머이송실린더(110)(112)에 의해 파워해머(100)가 천공홀(22)의 내측 돌출부위(26)를 향해 전진하는 경우, 해머비트(102)에 의해 돌출부위(26)가 제거되고, 해머이송실린더(110)(112)에 의해 파워해머(100)가 천공홀(22)의 내측 돌출부위(26)로부터 멀어지는 방향으로 후퇴하는 경우, 해머비트(102)가 천공홀(22)의 내측 벽면(24)으로부터 이격되어 본 발명의 장치를 천공홀(22)로부터 빼낼 때 간섭을 피하도록 하는 작용을 하게 된다.At this time, when the power hammer 100 advances toward the inner protrusion 26 of the drilling hole 22 by the hammer transfer cylinders 110 and 112, the protrusion 26 is removed by the hammer bit 102. When the power hammer 100 is retracted by the hammer transfer cylinders 110 and 112 in a direction away from the inner protruding portion 26 of the drilling hole 22, the hammer bit 102 is drilled into the drilling hole 22. It is spaced apart from the inner wall 24 of the to act to avoid interference when withdrawing the device of the present invention from the drilling hole 22.
