이와 같이 구성된 본 발명에 따른 이동식 교량 점검작업차를 바닥판 저면에설치하여 작업을 행하고자 할 경우에는, 첨부된 도면 도 1 내지 도 5에 도시된 바와 같이 작업자가 작업대에 승차한 후, 이동하고자 조작부를 조작하는 것에 대응되게 동력전달수단(150)의 정,역구동모터(151)가 구동하게 된다.When the mobile bridge inspection work vehicle according to the present invention configured as described above is to be installed on the bottom plate bottom to perform work, as shown in FIGS. In response to operating the operation unit, the forward and reverse driving motors 151 of the power transmission unit 150 are driven.

상기 정,역구동모터(151)의 구동으로 구동력을 감속기(152)를 통하여 감속되고, 감속된 구동력은 상기 동력전달수단(150)의 변위각도조절부(153)측으로 전달된다.The driving force is decelerated through the reducer 152 by the driving of the forward and reverse driving motors 151, and the reduced driving force is transmitted to the displacement angle adjusting unit 153 of the power transmission unit 150.

상기 변위각도조절부(153)측으로 구동력이 전달되면, 상기 변위각도조절부(153)의 양측에 일단이 회전가능하게 연결된 동력전달수평바(154)가 각 동일방향으로 각각 회전하게 된다. When the driving force is transmitted to the displacement angle control unit 153 side, the power transmission horizontal bar 154, one end of which is rotatably connected to both sides of the displacement angle control unit 153, respectively, rotates in the same direction.

상기 동력전달수평바(154)의 회전으로 제1동력전달용베벨기어부(154a)와 기어물림된 동력전달용수직바(155)가 회전하게 된다.Rotation of the power transmission horizontal bar 154 causes the first power transmission bevel gear portion 154a and the geared transmission vertical bar 155 to be rotated.

상기 동력전달용수직바(155)의 회전으로 동력전달용 연결부재(156)를 매개로 회전가능하게 연결된 동력전달연결바(158)이 회전하게 되고, 상기 동력전달연결바(158)의 회전으로 제3동력전달용베벨기어부(158a)와 기어 물림된 연결부재(10)의 베벨기어(16)가 회전하게 된다.Rotation of the power transmission vertical bar 155 causes the power transmission connecting bar 158 rotatably connected via the power transmission connecting member 156 to rotate, and by the rotation of the power transmission connecting bar 158. The bevel gear portion 158a for the third power transmission and the bevel gear 16 of the coupling member 10 that is geared to rotate are rotated.

이때, 이동바퀴가 곡선 이동레일을 주행할 경우, 즉, 작업대(130) 우측 방향으로 이동할 경우에는, 동력전달수단의 변위각도조절부(153)에 의해 동력전달수평바(154)가 서로 반대 방향으로 회전하는 것에 의해 작업대(130)의 이동이 가능하게 된다. At this time, when the moving wheel travels on the curved moving rail, that is, when moving to the right side of the work table 130, the power transmission horizontal bar 154 by the displacement angle adjusting unit 153 of the power transmission means are opposite to each other. The worktable 130 can be moved by rotating it.

즉, 이동바퀴가 곡선 이동레일을 주행하게 되면, 도 1에 도시된 바와 같이 동력전달수단(150)의 변위각도조절부(153) 상부측에 연결된 동력전달수평바(154)는 반시계방향으로 회전하게 되고, 변위각도조절부(153)의 하부에 연결된 동력전달수평바(154)는 시계방향으로 회전하게 되어 유니버셜죠인트를 갖는 동력전달용 연결부재(156)를 통하여 동력이 전달되므로 곡선 이동레일에서도 이동바퀴가 이동레일에 걸림됨 없이 주행하게 된다.That is, when the moving wheel runs on the curved moving rail, as shown in FIG. 1, the power transmission horizontal bar 154 connected to the upper side of the displacement angle adjusting unit 153 of the power transmission means 150 is counterclockwise. The power transmission horizontal bar 154 connected to the lower portion of the displacement angle adjusting unit 153 rotates in a clockwise direction so that power is transmitted through the power transmission connecting member 156 having a universal joint. Even in the moving wheel is traveling without being caught in the moving rail.

즉, 상기한 이동식 교량 점검작업차는 동력전달수단(150)의 변위각도조절부(153)에 의해 교량의 저면에 바닥판 저면에 설치된 이동레일의 설치형태에 대응되게 곡선 및 직선 이동이 가능하게 되므로 작업을 보다 신속하고 편리하게 행할 수 있게 된다.That is, the movable bridge inspection work vehicle is capable of moving in a curved line and a straight line corresponding to the installation form of the movable rail installed on the bottom surface of the bottom plate by the displacement angle adjusting unit 153 of the power transmission means 150. The work can be performed more quickly and conveniently.
