Description

선박용 사다리의 회전장치Rotating Device of Ship Ladder

본 고안은 선박용 사다리의 개량에 관한 것이며, 더욱 상세하게는 인양윈치로 끌어올려진 사다리를 선체 안으로 끌어들여 안전하게 보관하며 선박이 항구에 정박할 경우 사다리를 외판 밖으로 끌어내어서 수면위로 사다리를 내려뜨려 승하선 인원의 통행이 가능토록 하고, 또한 선박이 부두에 접안했을 때 사다리를 부두 지면에 내려 안전하게 사용할 수 있도록 하는 이 모든 일련의 작동을 선박측에서 가능케 한 것이다.The present invention relates to the improvement of the ladder for ships, and more particularly, the ladder pulled up by the lifting winch into the hull for safekeeping. When the ship is anchored in the port, the ladder is pulled out of the shell to lower the ladder onto the water surface. All of these operations were made possible on the ship's side, allowing the loading and unloading personnel to pass, and also allowing the ladder to be safely lowered to the ground when the ship docked at the dock.

대형 화물선 등 일반적으로 승선용 사다리는 선실이 위치한 선박의 선미 쪽에 설치되는데 이 경우 선박의 외판이 만곡이 심하여 부두에 접안할 때 선박과 부두간의 거리가 멀어서 사다리를 돌려 내어야만 부두에 안착시킬 수 있다.In general, a boarding ladder, such as a large cargo ship, is installed on the stern side of the ship where the cabin is located.In this case, the outer shell of the ship is so curved that when docked to the dock, the distance between the ship and the dock is far enough so that the ladder can be seated on the dock. .

이제까지 사용되고 있는 선박용 사다리는 사다리 하단부에 끈을 매달아 부두 쪽에서 사람이 사다리를 끌어서 당기거나 사다리의 하부답판에 부교 등을 추가로 설치하여 부두와 선박간의 통행이 가능토록 하고 있는 실정이다.The ladders used in ships are hung by ropes at the bottom of the ladders, so that people can pull the ladders from the pier side or install additional bridges on the bottom of the ladders to allow traffic between the docks and the ships.

그러나, 이러한 경우는 부두에 항상 사람이 대기하여야 하는 불편함이 있고 사다리를 돌려낼 때 사다리를 매달고 있는 로우프의 손상이 우려되며, 또한 부교를 설치하는 경우에는 시간낭비와 별도의 장비가 필요하게 될 뿐만 아니라 항상 위험요소가 따랐다.However, in this case, there is always inconvenience to wait on the pier, and when the ladder is returned, there is concern about damage to the ropes hanging on the ladder, and when the pontoon is installed, time waste and extra equipment are required. In addition, there were always risks.

본 고안은 종래의 선박용 사다리의 문제점을 해소하고자 안출한 것으로, 사다리를 내렸을 때 부두와의 거리에 따라 사다리의 횡각을 임의로 조정할 수 있게 함으로써 사다리를 부두 지면에 안착시켜 선박과 부두간의 통행을 안전하면서 편리하게 할 수 있도록 하고, 또한 일련의 모든 작동을 선박측에서 조작 가능케 구성한 선박용 사다리의 회전장치를 제공하는데 그 목적이 있다.The present invention was devised to solve the problems of the conventional ship ladder, and when the ladder is lowered, the ladder's horizontal angle can be arbitrarily adjusted according to the distance to the dock, thereby allowing the ladder to rest on the surface of the dock and safe passage between the ship and the dock. It is an object of the present invention to provide a rotating device of a ship ladder, which can be made convenient, and which can be operated on the ship side in a series of operations.

도 1에서, 본 고안에 의한 선박용 사다리의 회전장치는 사다리(4)를 외판((2) 밖으로 밀어내거나 갑판(1) 안으로 끌어들이는 격납장치(100)와, 사다리(4)를 끌어 올리고 내려뜨리는 회전장치(200)와, 사다리(4)를 횡방향으로 회전시켜 횡각(橫角)을 조절하는 주행장치(300)로 구성되어 있다.In FIG. 1, the rotating device of the ship ladder according to the present invention pulls up and down the containment device 100 and the ladder 4, which pushes the ladder 4 out of the outer plate 2 or into the deck 1. It consists of the rotating device 200 which floats, and the traveling device 300 which adjusts a horizontal angle by rotating the ladder 4 in a horizontal direction.

격납장치(100)는 갑판(1)상에서 선폭 방향으로 부착한 격납레일(13)에 사다리(4) 고정단측의 회전답판(15)이 축끼움된 상부답판(16)을 끼우고, 상기 격납레일(13)의 측방에는 격납윈치(7)를 설치하여 이 격납윈치(7)에 감긴 격납로우프(10)가 격납레일(13)내를 거치도록 두른 후 격납레일(13)내의 격납로우프(10)상에 상부답판(16)을 고정시켜 격납로우프(10)의 선회방향에 따라 상부답판(16)이 격납레일(13)의 내측단 또는 외측단 쪽으로 직선 이동되어 사다리(4)를 밀어내거나 끌어들이게 한다.The containment device 100 fits the upper answer plate 16 on which the rotary answer plate 15 on the fixed end side of the ladder 4 is fitted to the containment rail 13 attached on the deck 1 in the line width direction. On the side of (13), a storage winch (7) is installed, the storage rope (10) wound around the storage winch (7) is passed through the storage rail (13), and the storage rope (10) in the storage rail (13). The upper answer plate 16 is fixed on the top of the containment rope 10 so that the upper answer plate 16 moves linearly toward the inner end or the outer end of the containment rail 13 to push or pull the ladder 4. do.

회전장치(200)는 갑판(1)상의 일점에 설치된 축(11)을 중심으로 회전하는 붐(12)의 후단부에 인양윈치(5)를 탑재하고, 이 인양윈치(5)에 감긴 인양로우프(8)는 선단의 활차구(18)를 거쳐내려서 사다리(4)의 자유단측에 연결시켜 인양로우프(8)를 감아들이면 사다리(4)가 올려지고 인양로우프(8)를 풀어내면 사다리(4)는 자중에 의하여 내려지게 한다.The rotating device 200 mounts the lifting winch 5 at the rear end of the boom 12 that rotates about the shaft 11 installed at one point on the deck 1, and the lifting rope wound around the lifting winch 5. (8) is connected to the free end side of the ladder (4) by passing through the pulley (18) of the tip to wind the lifting rope (8), the ladder (4) is raised and the lifting rope (8) is released, the ladder (4) ) Is let down by own weight.

주행장치(300)는 상기 회전장치(200)의 후위에 주행레일(17)을 위치시켜 그 측방에 주행윈치(6)를 설치하고, 이 주행윈치(6)에 감긴 주행로우프(9)를 주행레일(17)을 거치도록 두른 후 주행로우프(9)상에 주행레일(17)을 타고 이동하는 주행구(19)를 고정한다.The traveling device 300 places the traveling rail 17 at the rear of the rotary device 200, installs the traveling winch 6 on the side thereof, and travels the traveling rope 9 wound around the traveling winch 6. After the rail 17 is passed through, the driving hole 19 is fixed on the driving rope 9 by moving on the driving rail 17.

또, 주행구(19)에는 수평으로 접어지고 펴지는 연결대(20)의 후단을 힌지방식으로 연결하는 한편, 그 외측단을 상기 회전장치(200)의 붐(12)에 역시 힌지방식으로 연결하여 주행구(19)가 주행로우프(9)의 선회방향에 따라 주행레일(17)의 전단 또는 후단 쪽으로 직선 이동할 때 축(11)을 중심으로 붐(12)을 회전시켜 사다리(4)의 횡각을 조절되도록 구성한 것이다.In addition, while connecting the rear end of the connecting table 20 which is horizontally folded and extended to the runway 19 in a hinged manner, the outer end is also connected to the boom 12 of the rotary device 200 in a hinged manner. When the driving port 19 linearly moves toward the front end or the rear end of the travel rail 17 along the turning direction of the travel rope 9, the boom 12 is rotated about the shaft 11 to adjust the transverse angle of the ladder 4. It is configured to be adjusted.

도면중 미설명부호 3은 부두, 14는 갑판 위로 끌어들여온 사다리(4)를 얹어 두는 재치대를 표시한다.In the drawings, reference numeral 3 denotes a wharf, and 14 denotes a mounting table on which a ladder 4 drawn onto a deck is placed.

도 1에서, 사다리(4)의 "a" 위치는 갑판(1)내에서의 재치대(14) 위에 사다리(4)가 격납된 위치, "b" 위치는 선박이 외항에 정박하여 사다리(4)를 사용하고자 할 경우의 위치, 그리고 "c" 위치는 선박이 부두에 접안하여 사다리(4)를 부두(3) 지면에 내리고자 할 경우의 위치를 표시한 것이다.In FIG. 1, the position "a" of the ladder 4 is a position where the ladder 4 is stored on the mounting table 14 in the deck 1, and the position "b" is a position where the ship is anchored in the outer port. The position "c" and the position "c" indicate the position when the vessel is docked to the pier and the ladder 4 is to be lowered to the pier 3 ground.

사다리(4)가 "a" 위치에 있을 때는 주행장치(300)에서 주행구(19)가 주행레일(17)의 전단 쪽인 "A" 위치에 머물게 됨에 따라 연결대(20)는 접어지고 붐(12)은 축(11)을 중심으로 회전된 상태이므로 그 선단의 활차구(18)가 갑판(1) 위인 즉, 선체 안에 있게 된다.When the ladder 4 is in the "a" position, as the driveway 19 stays at the "A" position, which is the front side of the travel rail 17, in the traveling device 300, the connecting rod 20 is folded and the boom 12 ) Is rotated about the shaft (11) so that the pulley 18 of the tip is above the deck (1), that is, in the hull.

선박이 외항에 정박할 경우에는 사다리(4)를 "a" → "b" 위치로 이동하여 사다리(4)를 수면 위로 내려뜨린다.When the vessel is anchored in the outboard port, the ladder 4 is moved to the position "a" → "b" to lower the ladder 4 above the surface of the water.

먼저, "a" → "b" 위치로의 사다리(4)의 이동을 위한 각도변경은 주행장치(300)를 활용한다.First, the angle change for the movement of the ladder 4 from the position "a" to the position "b" utilizes the traveling device 300.

즉, 주행윈치(6)를 구동시켜 주행로우프(9)에 연결된 주행구(19)가 주행레일(17)을 따라 이동하여 "B" 위치에 오게 하면 연결대(20)가 펴지면서 붐(12)을 축(11)을 중심으로 회전시켜 사다리(4)의 자유단측을 외판(2) 밖으로 옮겨준다.That is, when the driving winch 6 is driven so that the driving hole 19 connected to the driving rope 9 moves along the driving rail 17 to the "B" position, the connecting rod 20 is extended and the boom 12 is opened. Rotate around the shaft 11 to move the free end side of the ladder 4 out of the outer plate 2.

이와 동시에 격납장치(100)의 격납윈치(7)도 구동시켜 격납로우프(10)에 연결된 상부답판(16)을 외판(2) 쪽으로 밀어내면 격납레일(13)상에서 미끄러지듯 이동하므로, 상부답판(16)에 종속돼 있는 사다리(4)의 고정단측도 상부답판(16)과 같이 "b" 위치로 이동하여 선체와 평행상태를 이룬다.At the same time, by driving the containment winch 7 of the containment device 100 and pushing the upper answer plate 16 connected to the containment rope 10 toward the outer plate 2, the upper answer plate slides on the containment rail 13. The fixed end side of the ladder 4 subordinate to 16 is also moved to the position "b" like the upper answer plate 16 to form a parallel state with the hull.

이어서, 도 2의 측면도에 나타난 바와 같이 회전장치(200)의 인양윈치(5)를 구동시켜 인양로우프(8)의 풀림으로 사다리(4)가 자중에 의하여 수면 위로 내려지게 한 후 정지시킨다.Subsequently, as shown in the side view of FIG. 2, the lifting winch 5 of the rotating device 200 is driven to free the lifting rope 8 so that the ladder 4 is lowered onto the surface by its own weight and then stopped.

선박이 부두에 접안할 경우에는 상기 과정중 사다리(4)를 "a" → "b" 위치로 이동시킨 후 사다리(4)를 내려뜨리는 과정까지는 동일하다.When the ship is docked at the dock, the process of moving the ladder 4 to the position "a"-" b "

다만, 여기서는 사다리(4)를 내려뜨리는 과정에서 주행윈치(6)를 구동시켜 주행구(19)를 주행레일(17)상의 "C" 위치로 이동되게 하면 연결대(20)가 펴짐에 따라 붐(12)이 바깥 쪽으로 회전하여 사다리(4)의 자유단측을 밀어내어서 부두(3) 쪽으로 이동시킨다.However, in this case, the driving winch 6 is driven in the process of lowering the ladder 4 so that the driving port 19 is moved to the "C" position on the driving rail 17. 12) rotates outward to push the free end side of the ladder (4) to move toward the pier (3).

사다리(4)의 자유단측이 부두(3)의 "c" 위치에 옮겨진 후에 사다리(4)가 부두(3)의 지면에 닿도록 인양로우프(8)를 풀어내면 안전하게 놓이게 된다.After the free end side of the ladder 4 is moved to the "c" position of the pier 3, the ladder 4 is released safely by releasing the lifting rope 8 such that the ladder 4 touches the ground.

이러한 과정에서 사다리(4)는 붐(12) 선단의 활차구(18)를 통해 인양로우프(8)와 연결된 것이므로 인양로우프(8)의 인장력에 의해 활차구(18)가 붐(12)의 선단에서회전하면서 항상 사다리(4)의 길이방향과 수직을 유지하게 된다.In this process, since the ladder 4 is connected to the lifting rope 8 through the pulley 18 at the tip of the boom 12, the pulley 18 is distal to the tip of the boom 12 due to the pulling force of the lifting rope 8. Rotation at will always be perpendicular to the longitudinal direction of the ladder (4).

출항을 위해 사다리(4)를 갑판(1)내의 재치대(14) 위에 격납시키고자 할 경우에는 상기 과정을 역순으로 수행하면 된다.In order to store the ladder 4 on the mounting table 14 in the deck 1 for sailing, the above process may be performed in the reverse order.

즉, 인양윈치(5)와 주행윈치(6)를 역방향으로 구동시켜 사다리(4)의 자유단측을 끌어올리면서 "b" 위치로 먼저 옮겨 놓은 후 주행윈치(6)와 격납윈치(7)를 동시에 구동시켜 사다리(4)를 "a" 위치로 이동시키면 선체 안의 재치대(14) 위에 사다리(4)가 얹히는 상태로 격납되는 것이다.That is, the lifting winch 5 and the driving winch 6 are driven in the reverse direction, while the free end side of the ladder 4 is lifted up and moved to the "b" position, and then the driving winch 6 and the storage winch 7 are moved. When the ladder 4 is moved to the "a" position by driving at the same time, the ladder 4 is stored on the mounting table 14 in the hull.

본 고안에 의한 선박용 사다리의 회전장치는 부두 조건에 따라 접안된 선박과 부두간의 거리가 멀리 떨어진 경우라도 별도의 장비를 추가함이 없이 사다리를 부두에 닿게 내릴 수 있으므로 사용이 편리할 뿐만 아니라 승선과 하선의 안전이 보장되고, 또한 선박측 사다리의 조종자 외에는 추가 인원이 필요치 않아 인건비를 절감할 수 있는 등의 효과가 기대되는 매우 유용한 고안이다.The rotating device of the ship ladder according to the present invention is easy to use because the ladder can be lowered to the pier without additional equipment even when the docked ship and the pier are far apart according to the pier conditions. It is a very useful design that guarantees the safety of the unloading, and it is possible to reduce the labor cost because no additional personnel are required except the operator of the ladder of the ship side.
