Description

정방향 유압펌프를 이용한 선박용 유압조타장치{STEERING GEAR}Marine hydraulic steering device using forward hydraulic pump {STEERING GEAR}

도면1에서 조타륜(2)을 시계 방향으로 회전시키면 유동레버(11)의 왼쪽(11a)이 해당각도 만큼 위로 올라간다. 즉 오른쪽(11b)은 고정상태가 되므로 비스듬한 상태가 되며, 가변토출펌프(10)의 조정봉(10c)이 위로 올라간다. 이로 인하여 가변토출펌프(10)의 오른쪽(10b)으로 유압이 가해지고, 유압실린더(2)의 오른쪽(2b)에 압력이 가해져 타심재(7)를 중심으로 틸러(4)는 왼쪽(4a) 방향으로 회전을 하게되며, 이에 연접봉(15)도 왼쪽으로 이동을 하여 유동레버(11)의 오른쪽(11b)이 아래 방향으로 내려간다. 유동레버(11)의 왼쪽(11a)은 고정된 상태이므로 가변토출펌프(10)의 조정봉(10c)은 처음상태로 되돌아 가게되어 가변토출펌프(10)의 오른쪽(10a)으로 가해지던 압력이 멈추게되어 동작은 끝이 난다.In FIG. 1, when the steering wheel 2 is rotated in the clockwise direction, the left 11a of the floating lever 11 is raised by the corresponding angle. That is, the right 11b is in an oblique state because it becomes a fixed state, and the adjusting rod 10c of the variable discharge pump 10 rises up. Due to this, the hydraulic pressure is applied to the right side 10b of the variable discharge pump 10, and the pressure is applied to the right side 2b of the hydraulic cylinder 2, so that the tiller 4 is centered on the left core 4. It rotates in the direction, the connecting rod 15 is also moved to the left to the right (11b) of the flow lever 11 is lowered downward. Since the left side 11a of the floating lever 11 is fixed, the adjusting rod 10c of the variable discharge pump 10 is returned to its initial state to stop the pressure applied to the right side 10a of the variable discharge pump 10. The action ends.

일반적으로 대형선박에서는 가변토출이 가능한 유압펌프를 이용하여 타를 회전시키고 원하는 각도에서 정지시킨다. 이에 따라 설치에 대한 비용이 많이 들고 설치공간을 많이 차지하여 소형선박 등에는 적합하지 않다.In general, large ships use a hydraulic pump capable of variable discharge to rotate the rudder and stop at a desired angle. As a result, it is expensive for installation and occupies a lot of installation space and is not suitable for small ships.

본 발명은 선박용 유압 조타장치이며, 토출방향이 일정한 일반기어 펌프와 솔레노이드 밸브를 결합하여 이를 이용하여 타를 회전시키고 추구장치 디스크, 추구장치 캠, 리미트 스위치, 베어링을 결합하여 원하는 각도에서 정지할 수 있으며, 종래의 복잡한 구조가 간단하게 되어 설치공간이 줄어들고 설치가 용이하고, 설치비용이 적게드는 유압펌프를 이용한 선박용 유압조타장치를 제공하기 위한 것이다.The present invention is a hydraulic steering device for ships, by combining the general gear pump and the solenoid valve with a constant discharge direction using the same to rotate the rudder and combine the seek device disk, seek device cam, limit switch, bearing can be stopped at a desired angle. In addition, the conventional complicated structure is simplified to reduce the installation space, easy to install, and to provide a hydraulic pressure steering apparatus for ships using a hydraulic pump having a low installation cost.

본 발명은 선박을 원하는 방향으로 전환 또는 유지하기 위한 발명으로서, 저렴한 설치비용과 좁은 설치면적, 간편한 설치작업의 효과를 제공한다.The present invention is an invention for converting or maintaining a vessel in a desired direction, and provides an effect of low installation cost, narrow installation area, and simple installation work.

본 발명의 도면2, 도면5의 조타륜(5)을 원하는 방향, 각도만큼 회전시키면 추구장치 디스크(6)는 같은 방향, 같은 각도만큼 회전을 하고, 리미트 스위치(6a, 6b)도 또한 동시에 같은 방향, 같은 거리만큼 이동한다.When the steering wheel 5 of Figs. 2 and 5 of the present invention is rotated by the desired direction and angle, the seeking device disk 6 rotates by the same direction and the same angle, and the limit switches 6a and 6b are also the same. Direction, move the same distance.

즉, 조타륜(5)이 반시계방향으로 회전을 하면 추구장치 디스크(6)도 반시계방향으로 회전을 하여 리미트 스위치도 반시계방향으로되면 리미트 스위치(6b)는 접점(on)이 되고 리미트 스위치(6a)는 접점이 되지 않은(off) 상태가 된다. 리미트 스위치(6b)가 접점이 되어 도면2, 도면4의 솔레노이드 밸브(3)의 전자코일(3b)이 여자되어 유압실린더(2b)에 압력이 가해지게되고, 틸러(4)는 왼쪽 방향(4a)으로 이동되며, 틸러(4)가 이동하면서 틸러(4), 타심재(7),추구장치 캠(8)은 항상 같은 방향, 같은 각도만큼 움직이게 되어 있어서 추구장치 캠(8)이 반시계방향으로 회전하면 리미트 스위치(6b)의 접점이 끊어지고, 리미트 스위치(6a)는 접점이 끊어진 상태에서 아무런 변화가 생기지 않고 그대로 끊어진 상태를 유지한다. 리미트 스위치(6b)의 접점이 끊어져서 솔레노이드 밸브(3)의 전자코일(3b)이 다시 소자되어 유압실린더(2b)방향으로 가해지던 압력이 멈추게 되어 틸러(4)는 해당 방향, 각도만큼 이동을 하고 동작은 끝이 난다.That is, when the steering wheel 5 rotates in the counterclockwise direction, when the pursuit device disk 6 also rotates in the counterclockwise direction, when the limit switch is also in the counterclockwise direction, the limit switch 6b becomes the contact (on) and the limit is on. The switch 6a is in an off state. The limit switch 6b is brought into contact, and the electromagnetic coil 3b of the solenoid valve 3 of FIGS. 2 and 4 is excited to apply pressure to the hydraulic cylinder 2b, and the tiller 4 is in the left direction 4a. ), While the tiller 4 moves, the tiller 4, the core member 7, and the purging device cam 8 are always moved in the same direction and at the same angle, so that the seeking device cam 8 is counterclockwise. When it rotates by, the contact of the limit switch 6b is cut off, and the limit switch 6a maintains the disconnected state without any change in the state in which the contact was broken. The contact point of the limit switch 6b is broken and the electromagnetic coil 3b of the solenoid valve 3 is demagnetized again, and the pressure applied to the hydraulic cylinder 2b is stopped so that the tiller 4 moves by the corresponding direction and angle. The action ends.

이상에서와 같이 본 발명은 비용이 적게들면서도 작은 공간에 설치하기가 용이하며, 유압펌프와 유압실린더 사이의 거리제한을 두지 않으므로 메인 엔진에서 직접 동력을 얻어 사용할 수 있으며, 설치, 제작이 용이하다.As described above, the present invention is easy to install in a small space at a low cost, and does not limit the distance between the hydraulic pump and the hydraulic cylinder can be directly used to obtain power from the main engine, it is easy to install, manufacture .
