이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보기로 한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저, 본 발명의 일 실시 예에 따른 터빈로터 터닝장치의 구조를 도 1 내지 도 6을 통해 살펴보면, 양측의 베이스 플레이트(4) 사이에서 베어링(미도시)에 의해 회전 가능하게 지지되는 다수의 터빈로터(1)는 상호간의 연결부위에 커플링(2)이 구성되어져 있으며, 커플링(2)에는 둘레를 따라 볼트 체결을 위한 다수의 통공(3)이 관통 형성되어져 있어 양측 커플링(2)간 연결 결합이 가능한 구조를 이루고 있다.First, referring to the structure of the turbine rotor turning apparatus according to an embodiment of the present invention through FIGS. 1 to 6, a plurality of turbines rotatably supported by bearings (not shown) between base plates 4 on both sides. The rotor (1) has a coupling (2) is formed in the connection portion between each other, the coupling (2) is formed through a plurality of through holes (3) for fastening bolts along the circumference, both couplings (2) It is a structure that can be connected to each other.

한편, 본 발명의 터닝장치는 상기 통공(3)에 삽입 가능하도록 일정 길이를 갖는 터닝바(10)와, 상기 터닝바(10)에 가압력을 전달하기 위한 구동실린더(20)와, 상기 구동실린더(20)의 실린더로드(21) 선단부에 장착되며 일측에는 터닝바(10)가 삽입 지지되어질 수 있는 삽입홈(31)이 형성된 클램프(30)와, 상기 구동실린더(20) 후단이 힌지핀(41)에 의해 회동 가능하게 결합되며 로터(1)가 안착되어져 있는 베이스플레이트(4)에 고정 설치되는 서포터(40)로 구성되어져 있다.On the other hand, the turning device of the present invention is a turning bar 10 having a predetermined length to be inserted into the through hole 3, a drive cylinder 20 for transmitting a pressing force to the turning bar 10, and the drive cylinder Clamp 30 is mounted to the end of the cylinder rod 21 of the 20 and the insertion groove 31 is formed on one side to be supported by the turning bar 10, and the rear end of the driving cylinder 20 is a hinge pin ( It is composed of a supporter 40 which is rotatably coupled by 41 and fixedly installed on the base plate 4 on which the rotor 1 is seated.

특히, 클램프(30)에 형성된 삽입홈(31)은 반원형상을 이루고 있으며, 이와 대응되는 터닝바(10)에는 클램브가 안정적으로 지지되어질 수 있도록 지지홈(11)이 형성되어져 있음을 도 5를 통해 확인할 수 있다.In particular, the insertion groove 31 formed in the clamp 30 has a semi-circular shape, and the support bar 11 is formed in the turning bar 10 corresponding thereto so that the clamp can be stably supported. You can check it through

본 실시 예에서의 구동실린더(20)는 유압에 의해 구동되어지는 것으로서 일측에는 유체 공급을 위한 유압유니트가 연결 구비되어지게 된다.The drive cylinder 20 in the present embodiment is driven by hydraulic pressure, one side is provided with a hydraulic unit for supplying a fluid.

이와 같은 구성을 이루는 본 발명 터닝장치를 이용한 터빈로터 터닝작업 과정을 살펴보기로 한다.The turbine rotor turning process using the present invention turning device constituting such a configuration will be described.

먼저, 구동실린더(20)가 연결 구성된 상태의 서포터(40)를 베이스 플레이트(4)에 고정 설치함과 함께 체결볼트가 제거된 커플링(2)의 통공(3)에 터닝바(10)를 삽입설치한다.First, the support bar 40 is fixed to the base plate 4 while the driving cylinder 20 is connected, and the turning bar 10 is inserted into the through hole 3 of the coupling 2 from which the fastening bolt is removed. Insert and install.

그리고, 클램프(30)의 삽입홈(31)을 도 5 및 도 6에서와 같이 터닝바(10) 일측에 형성된 지지홈(11)에 삽입하여 상호간에 지지되어질 수 있도록 한 상태에서, 작업자가 전원을 인가하여 구동실린더(20)를 구동시키게 되면 도 3 및 도 4에 나타난 바와 같이 실린더로드(21)가 전진되어지면서 터빈로터(1)가 일정 각도로 회전되어지게 된다.In addition, the operator inserts the insertion groove 31 of the clamp 30 into the support groove 11 formed at one side of the turning bar 10 as shown in FIGS. 5 and 6 so that the operator can be mutually supported. When the driving cylinder 20 is applied by applying the cylinder rod 21 is advanced as shown in Figure 3 and 4, the turbine rotor 1 is rotated at a predetermined angle.

즉, 유압 구동력에 의해 실린더로드(21)가 전진되어짐에 따라 클램프(30)가 터닝바(10)를 밀어주게 되고, 따라서 커플링(2)과 일체로 구성된 터빈로터(1)가 해당 운동량 만큰 회전이 이루어지게 되는 것이다.That is, as the cylinder rod 21 is advanced by the hydraulic driving force, the clamp 30 pushes the turning bar 10, and thus the turbine rotor 1 integrally formed with the coupling 2 has a large amount of momentum. Rotation will be made.

그리고, 일정 각도로의 회전이 완료되면 구동실린더(20)를 복귀시킨 후 터닝바(10)를 분리시키고 다시 커플링(2)의 다른 위치 통공(3)에 삽입시켜서 클램프(30)를 지지시켜 다음 터닝작업을 준비하게 된다.When the rotation is completed at a predetermined angle, the driving cylinder 20 is returned, and then the turning bar 10 is separated and inserted into another position hole 3 of the coupling 2 to support the clamp 30. You will be ready for the next turning.

따라서, 이러한 작업을 반복함으로서 원하는 각도로의 터빈로터 터닝작업이 신속하고 용이하게 이루어질 수 있게 됨을 알 수 있다.
Therefore, it can be seen that by repeating this operation, the turbine rotor turning operation at a desired angle can be made quickly and easily.

한편, 도 7은 본 발명의 응용예에 따른 터닝바(10)와 클램프(30) 상호간 결합부 구조를 단면으로 나타낸 것으로서, 터닝바(10)의 지지홈(11) 및 클램프(30)의 삽입홈(31)에는 상호간 치합을 위한 요철부(11a,31a)를 각각 형성시킨 것이다.On the other hand, Figure 7 is a cross-sectional view showing the structure of the coupling between the turning bar 10 and the clamp 30 according to the application of the present invention, the insertion of the support groove 11 and the clamp 30 of the turning bar 10 The grooves 31 are formed with uneven portions 11a and 31a for mutual engagement, respectively.

이와 같이 요철부(11a,31a) 구조를 형성시키게 되면 터닝바(10)를 밀어주는 과정에서 클램프(30)와 터닝바(10) 상호간의 슬립현상이 방지되고 작업 과정에서 보다 안정적인 결합상태가 유지되어질 수 있어 정밀한 터닝작업이 이루어질 수 있게 된다.As such, when the uneven parts 11a and 31a are formed, slip between the clamp 30 and the turning bar 10 is prevented in the process of pushing the turning bar 10, and a more stable coupling state is maintained in the working process. It can be made so that precise turning work can be made.

또한, 도 8은 본 발명의 다른 응용예 구성을 나타낸 것으로서, 실린더로드(21)의 외표면에 터빈로터(1) 표면과의 마찰에 따른 손상 방지를 위한 우레탄 완충패드(22)를 일정 두께로 구비한 것이다.In addition, Figure 8 shows another configuration of the application of the present invention, the outer surface of the cylinder rod 21, the urethane buffer pad 22 for preventing damage caused by friction with the surface of the turbine rotor (1) to a predetermined thickness It is equipped.

즉, 로터 터닝과정에서 실린더로드(21)가 최대로 전진이동되었을 때 도 4에서 나타내어지는 바와 같이 터빈로터(1)의 표면과 마찰이 발생할 수 있게 되고, 이에 따른 기기손상 내지는 변형이 발생하는 문제점이 나타나게 된다.That is, when the cylinder rod 21 is moved forward in the rotor turning process, as shown in FIG. 4, friction with the surface of the turbine rotor 1 may occur, thereby causing damage to the device or deformation. Will appear.

따라서, 이러한 문제 개선을 위해 우레탄 완충패드(22)로 실린더로드(21)의 외주면을 감싸주도록 함으로서 터빈로터(1)와의 접촉에 따른 악영향 발생을 미연에 예방할 수 있게 된다.
Therefore, the urethane buffer pad 22 is wrapped around the outer circumferential surface of the cylinder rod 21 in order to improve such a problem, thereby preventing adverse effects due to contact with the turbine rotor 1.
