When the hydraulic motor 37 is driven by pressure supplied to the hydraulic port 43, the worm shaft 44 The worm gear 35 is rotated by the rotation of the worm 36 and the rotation of the worm gear 35 is transmitted to the pinion gear 34 via the pinion gear 34 and the worm gear 35, And the rotating force is transmitted to the pinion gear 34 to move the rack-like rod 33.

웜(36)의 회전을 통하여 웜기어(35), 피니언기어&웜기어 축(39), 피니언기어(34), 래크기어 로드(33)의 순서로 움직이게 되며, 이러한 운동은 일방향으로만 동력이 전달되는 방식 즉, 래크기어 로드(33)에 걸리는 하중이 웜(36)으로 전달되기는 하지만 웜(36)을 회전시키지는 못하므로 래크기어 로드(33)가 움직일 수 없어 안전을 확보하는 방안이 된다.
The worm gear 35, the pinion gear 34 and the pinion gear 33 move in this order through the rotation of the worm 36 and the motions of the worm gear 35, the pinion gear and the worm gear 39, In other words, although the load applied to the rack-size rod 33 is transmitted to the worm 36, the rack-rod rod 33 can not move because the worm 36 can not be rotated, thereby securing safety .

도 4는 기어박스장치(45)의 래크기어 로드(33)의 전진 상태 즉, 어태치먼트를 체결 및 탈착하는 이동후크(19)를 움직여 어태치먼트를 체결한 상태를 나타내는 도면이며, 도 5는 기어박스장치(45)의 래크기어 로드(33)의 후진 상태 즉, 어태치먼트를 체결 및 탈착하는 이동후크(19)를 움직여 어태치먼트를 탈착한 상태를 나타내는 도면이다.

7, the movable hook 19 restrains the second engaging pin 21 and the state shown in Fig. 5, that is, the state shown in Fig. 5, When the size rod 33 is in the retracted state, the movable hook 19 is in a state in which the second engagement pin 21 is released from the restraint state as shown in Fig.

도 8은 이동후크(19)의 구성을 나타내는 부분단면도로써, 이동후크(19)의 연결홈부에 이동후크(19)에 삽입되는 이동후크 연결핀(20)에 의해 연결부위의 마모시에 수리를 간편하게 하고 조립시 간격을 조절하기 위한 이동후크 T-부싱(24)가 삽입되며, 하부몸체경판(11)에 연결핀 T-부싱(22)을 용접하여 하부몸체경판(11)이 찢어지는 것을 방지하고 강도를 강화한다. 또한 이동후크 연결핀(20)의 탈착을 방지하기 위하여 연결핀고정용칼라(25)를 이동후크 연결핀(20)에 삽입하고 볼트를 이용하여 고정한다.8 is a partial cross-sectional view showing the structure of the moving hook 19. The moving hook connecting pin 20 inserted into the moving hook 19 in the connecting groove portion of the moving hook 19 is repaired when the connecting portion is worn. The movable hook T-bushing 24 for insertion and adjustment of spacing during assembly is inserted and the connection pin T-bushing 22 is welded to the lower body end plate 11 to prevent the lower body end plate 11 from being torn And strengthen the strength. In order to prevent detachment of the movable hook connecting pin 20, the connecting pin fixing collar 25 is inserted into the moving hook connecting pin 20 and fixed using bolts.
