미설명부호 20은 포크레인암(ARM)이고Unexplained symbol 20 is forklift arm (ARM)

21은 포크레인링크이며21 is a fork lane link

22는 암석이다.22 is rock.

이와같이된 본 고안은 기존의 포크레인의 포크레인암(20)과 포크레인링크(21)에 도3에 도시한 바와같이 암체결판(16)의 체결구멍(4A)(4B)을 고정하여 암석(22)을 굴착코자할때는 실린더(10)를 작동하여 지지원통(5)및 회전관(7)을 상승시키고 상기의 회전관(7)에다 굴착관(8)을 나사결합시키는 한편, 굴착관(8)의 단부에는 다이야몬드치관(9)을 나사결합시키고 실린더(10)를 작동하여 피스톤로드(10A)와 지지원통(5)및 회전관(7)을 하강시켜 다이야몬드치관(9)을 암석(18)의 표면에 접촉시킨 후 유압모터(6)를 작동하여 다이야몬드치관(9)을 회전시키면서 실린더(10)의 피스톤로드(10A)를 서서히 하강시키게되면 암석(18)은 다이야몬드치관(9)에 의하여 굴착되어지게된다.The present invention as described above secures the rock 22 by fixing the fastening holes 4A and 4B of the female fastening plate 16 to the fork-lane arm 20 and the fork-lane link 21 of the existing fork-lane as shown in FIG. When drilling, the cylinder 10 is operated to raise the support cylinder 5 and the rotary tube 7 and to screw the drill tube 8 into the rotary tube 7, while the end of the drill tube 8 ends. The diamond toothed pipe 9 is screwed in, and the cylinder 10 is operated to lower the piston rod 10A, the support cylinder 5, and the rotary tube 7 so that the diamond toothed pipe 9 is removed from the rock 18. When the piston rod 10A of the cylinder 10 is slowly lowered while operating the hydraulic motor 6 by rotating the diamond tooth tube 9 after contacting the surface, the rock 18 is driven by the diamond tooth tube 9. To be excavated.

암석(22)을 경사상으로 굴착하기위하여 굴착기를 좌측 또는 우측경사방향으로 각도를 변위시키고자 할때는 지주(2)에 핀(13)으로 유착된 실린더(12)를 작동하여 피스톤로드(12A)를 도5의 점선화살표방향으로 이동시키게되면 포크레인암(21)과 브라켓(4)은 움직임없이 정지된 상태에서 지지판(11)은 축(401)을 축점으로 하여 도5와 같이 좌측으로 회전됨으로 좌측경사방향으로 굴착할 수 있으며 반대로 실린더(12)의 피스톤로드(12A)를 도5의 실선화살표방향으로 최대로 전진시키면 지지판(11)은 우측으로 회전됨으로 우측경사방향으로 굴착할 수 있다.In order to shift the angle of the excavator in the left or right inclined direction to excavate the rock 22 in an inclined shape, operate the cylinder 12 adhered to the support 2 with the pin 13 to operate the piston rod 12A. 5, the support plate 11 is rotated to the left as shown in FIG. 5 with the shaft 401 as the axial point while the fork lane arm 21 and the bracket 4 are stopped without moving. Can be excavated in the direction, and on the contrary, when the piston rod 12A of the cylinder 12 is maximally advanced in the solid arrow direction of FIG. 5, the support plate 11 can be excavated in the right inclined direction as it rotates to the right.

브라켓(4)을 수평으로 이동시켜 수직굴착코져 할때는 핸들너트(19)를 회전시켜 볼트(18)를 느슨하게 푼 다음 도4에 도시된 바와같이 브라켓(4)을 축(17)을 축점으로하여 좌우수평으로 회전시키면 브라켓(4)의 구멍(4A)에 끼워진 볼트(15)는 암체결판(16)의 호형안내구멍(160)을 따라 안내된다. 브라켓(4)을 수평으로 이동시킨 후에는 핸들너트(19)로 볼트(18)를 조아 브라켓(4)이 움직이지 못하도록 견고하게 고정하고 실린더(10)와 유압모터(6)의 작동에 의하여 다이야몬드치관(9)을 회전과 동시에 하강시키면서 수직으로 굴착하면되는데 브라켓(4)을 수평으로 이동시킨상태에서 실린더(12)에 의하여 지지판(11)을 회전시켜 경사상으로 굴착할 수 있음은 물론이다. 그리고 본 고안은 요지를 벗어나지 않는 범위내에서 구조를 소폭변경 할수도 있다.When moving the bracket 4 horizontally to make vertical excavation, turn the handle nut 19 to loosen the bolt 18, and then, as shown in Fig. 4, the bracket 4 is rotated left and right with the shaft 17 as the axis point. When rotated horizontally, the bolt 15 fitted into the hole 4A of the bracket 4 is guided along the arc-shaped guide hole 160 of the female fastening plate 16. After moving the bracket (4) horizontally, tighten the bolt (18) with the handle nut (19) to fix the bracket (4) firmly and prevent the movement of the cylinder (10) and the hydraulic motor (6) It is possible to excavate vertically while lowering the mond tooth pipe 9 at the same time as it rotates. Of course, the support plate 11 can be rotated by the cylinder 12 to be excavated in an inclined state while the bracket 4 is moved horizontally. . And the present invention can be modified a little within the scope without departing from the gist.

이와같은 본 고안은 브라켓(4)에다 포크레인에 고정하기위한 암체결판(16)을 축(17)으로 축설하여 브라켓(4)을 좌우수평으로 이동시켜 수직으로 굴착시킬 수 있도록 하였으므로 포크레인을 자유롭게 작동시킬 수 없는 협소한 공사장등의 암석(22)을 용이하게 수직으로 굴착제거할 수 있는 효과가 있다.The present invention is such that the arm fastening plate 16 for fixing to the forklift to the bracket (4) to the axis (17) to move the bracket (4) horizontally to excavate vertically to freely operate the forklift There is an effect that can be easily excavated and removed vertically rock (22) such as narrow construction.
