Description

부유체 시험용 계류로프 길이조절장치 및 그 작동방법Mooring rope length adjusting device for floating body test and its operation method
본 발명은 부유체 시험을 위한 계류로프 길이조절장치에 관한 것으로, 더욱 상세하게는 부유체를 수조에 부유시킨 상태에서 제반 성능 시험을 수행할 때 부유체에 연결된 계류로프의 길이를 조절할 수 있도록 한 부유체 시험용 계류로프 길이조절장치 및 그 작동방법에 관한 것이다.The present invention relates to a mooring rope length adjusting device for a floating body test, and more particularly, to adjust the length of the mooring rope connected to the floating body when performing the overall performance test in the state of floating the floating body in the tank. A mooring rope length adjusting device for floating body testing and a method of operating the same.
일반적인 선박 또는 해양구조물에 대한 성능시험은 선박 또는 해양구조물이 수면에서 설계조건에 의한 자세를 갖고, 원하는 특정 위치에 계류된 상태에서 파도, 바람, 조류 등의 해양환경 조건에서 해당 물체의 운동특성 등을 계측하는 것을 주요 내용으로 한다. Performance tests on general ships or offshore structures are based on the design conditions at the surface of the ships or offshore structures, and the motion characteristics of the objects under marine environment conditions such as waves, wind, and tidal currents while being anchored to a specific location. The main content is to measure.
이러한 선박 또는 해양구조물의 성능시험은 해양공학수조에서 수행할 수 있도록 하기 위하여 해당 선박이나 해양구조물에 대한 축소모형을 제작한 다음, 제작된 축소모형을 해양공학수조에 부유시키고, 부유된 축소모형(이하 부유체)의 운동을 구속하기 위하여 복수개의 계류로프로 지지하게 된다. 이 때 부유체에 연결된 계류로프의 끝단은 수조의 바닥면에 설치되어 있는 지지대에 고정된다. In order to be able to perform the performance test of such vessels or offshore structures, a scale model for the vessel or offshore structure is produced in order to be carried out in the offshore engineering tank, and then the produced scale model is suspended in the offshore engineering tank and the floating scale model ( In order to constrain the motion of the float), it is supported by a plurality of mooring loops. At this time, the end of the mooring rope connected to the float is fixed to the support installed on the bottom of the tank.
한편, 이와 같은 부유체 수조시험을 위해서 먼저 부유체와 계류로프 지지대의 배치 및 계류로프의 길이를 결정하고, 수조 밖에서 부유체와 계류로프 지지대를 계류로프와 연결한 후 수조 안에 이들을 배치하게 되는데, 이 때 수조 바닥에 설치되는 계류로프 지지대의 위치가 정확하지 않는 경우가 자주 발생하게 된다. 이 경우 계류로프의 길이를 변경해줄 필요가 있다. On the other hand, for such a float tank test, the arrangement of the float and the mooring rope support and the length of the mooring rope are first determined, and the float and the mooring rope support are connected to the mooring rope outside the tank, and then placed in the tank. At this time, the position of the mooring rope support that is installed on the bottom of the tank is often inaccurate. In this case, it is necessary to change the length of mooring ropes.
종래에는 계류로프의 길이를 조정하기 위해서 사람이 직접 수조 속으로 들어가서 계류로프의 길이를 변경하는 작업을 수행하였는데, 이와 같이 수조 속에서의 계류로프 길이 변경 작업은 불편하고 위험할 뿐만 아니라 많은 시간이 소모되는 문제가 있다. 특히 부유체의 크기가 작을 경우, 계류로프의 길이를 변경하는 데에 필요한 부가장치를 부유체에 설치하는 것이 어려워 계류로프 길이 조정 작업은 더욱 불편한 문제가 있다. Conventionally, in order to adjust the length of a mooring rope, a person directly enters the tank to change the length of the mooring rope. Thus, the changing of the mooring rope length in the water tank is not only inconvenient and dangerous, but also a lot of time. There is a problem of exhaustion. In particular, when the size of the floating body is small, it is difficult to install the additional device necessary to change the length of the mooring rope in the floating body, the mooring rope length adjustment operation is more inconvenient problem.

The cable 40 connecting the rotating bar 16 of the rope fixing tong 14 and the tongs operating unit 20 has a covering part 41 and the covering part 41 as shown in FIG. It is preferable that it is made of Bowden cable provided in the inside and provided with the internal line 45 which moves relative with respect to the covering part 41. FIG. The coating part 41 is formed of three layers of the plastic protective film 42, the metal coating material 43, and the inner sleeve 44, and allows the inner line 45 to move relatively inside the inner sleeve 44. It consists of an installed structure. Such Bowden cable 40 is commonly used as a cable for brake operation of the bicycle.
상기 집게작동유닛(20)은 수조의 외부에 설치되는 레버지지대(21)와, 상기 케이블(40)의 끝단부와 연결되며 상기 레버지지대(21)에 회전 운동 가능하게 설치되어 케이블(40)의 내선(45)을 당기는 작동레버(22)를 포함하여 구성된다. The forceps operating unit 20 is connected to the lever support 21 is installed on the outside of the tank, the end of the cable 40 and is installed on the lever support 21 so as to be rotatable movement of the cable 40 It comprises a working lever 22 for pulling the extension (45).
이와 같이 구성된 부유체 시험용 계류로프 길이조절장치는 다음과 같이 작동한다. The mooring rope length adjusting device for floating body test configured as described above operates as follows.
먼저 수조 외측에서 윈치(30)에 감겨진 계류로프(3)를 지지대(10)의 로프지지편(13)을 통과시킨 다음 계류로프(3)의 일단부를 부유체(2)에 연결한다. 이 때, 상기 계류로프(3)는 지지대(10)의 로프고정 집게(14)를 통과하게 되고, 계류로프(3)의 길이를 조정한 후 로프고정 집게(14)로 계류로프(3)를 파지하여 고정한다. First, the mooring rope 3 wound on the winch 30 from the outside of the tank is passed through the rope support piece 13 of the support 10, and then one end of the mooring rope 3 is connected to the floating body 2. At this time, the mooring rope (3) passes through the rope fixing tongs 14 of the support 10, after adjusting the length of the mooring rope (3) mooring rope (3) with the rope fixing tongs (14) Grip and fix.
그리고 상기 지지대(10)를 수조(1) 내부에 넣고 설정 위치에 안치시킨다. 이어서, 실험자가 상기 집게작동유닛(20)의 작동레버(22)를 누르면, 케이블(40)의 내선(45)이 당겨지면서 로프고정 집게(14)의 회동바아(16)가 탄성부재(17)의 탄성력을 이기고 힌지축(16a)을 중심으로 회전하여 계류로프(3)의 고정 상태가 해제된다. Then, the support 10 is placed in the tank 1 and placed in a set position. Subsequently, when the experimenter presses the operation lever 22 of the forceps operating unit 20, the inner bar 45 of the cable 40 is pulled, and the rotating bar 16 of the rope fixing tongs 14 moves to the elastic member 17. The fixing state of the mooring rope 3 is released by rotating about the hinge axis 16a and winning the elastic force of the.
이어서, 실험자가 윈치를 감거나 풀어서 계류로프(3)의 길이를 조절한다. 계류로프(3)의 길이를 원하는 길이로 조정한 다음, 실험자가 상기 작동레버(22)를 누르던 힘을 제거하면, 탄성부재(17)의 탄성력에 의해 로프고정 집게(14)의 회동바아(16)가 힌지축(16a)을 중심으로 이전과는 반대 방향으로 회전하여 회동바아(16)의 일단부가 고정바아(15)의 일단부에 밀착되면서 계류로프(3)를 견고하게 파지하여 고정하게 된다. The experimenter then adjusts the length of the mooring rope 3 by winding or unwinding the winch. After adjusting the length of the mooring rope (3) to the desired length, when the experimenter removes the force pressing the operating lever 22, by the elastic force of the elastic member 17, the rotating bar of the rope fixing tongs 14 16 is rotated in the opposite direction to the center of the hinge axis (16a) so that one end of the rotation bar 16 is in close contact with the one end of the fixed bar (15) to hold the mooring rope (3) firmly fixed do.
이와 같이 본 발명에 따르면, 수조(1) 외부에서 집게작동유닛(20)을 작동시켜 수조(1) 내부에 설치된 지지대(10)의 로프고정 집게(14)를 작동시켜 계류로프(3)의 지지 상태를 해제하고, 윈치(30)를 돌려 계류로프(3)의 길이를 원하는 길이로 조절할 수 있다. 따라서 계류로프(3)의 길이 조절 작업이 매우 신속하고 용이하게 이루어질 수 있다. Thus, according to the present invention, by operating the forceps operating unit 20 from the outside of the water tank 1 to operate the rope fixing tongs 14 of the support 10 installed inside the water tank 1 to support the mooring rope 3 The state is released, and the winch 30 can be turned to adjust the length of the mooring rope 3 to a desired length. Therefore, the length adjustment operation of the mooring rope 3 can be made very quickly and easily.
