Description
본 발명은 선박의 무링로프 보호장치에 관한 것으로, 특히 초크라이너를 연질의 플라스틱으로 된 일체형으로 구현하여 초크에 결합 사용함으로써 선박 고박용 무링로프를 안전하게 보호하고 장수명화를 달성할 수 있도록 개선된 선박의 무링로프 보호장치에 관한 것이다.The present invention relates to a device for protecting the no-ring rope of a ship, and in particular, an improved ship that can securely protect the no-ring rope for ship anchorage and achieve a long life by implementing a choke liner as an integral type of soft plastic and using it in combination with a choke. It relates to a mooring rope protection device
일반적으로, 페어리드(Fairlead)는 선박의 선수, 선미, 측면 모두에 설치되어, 선박의 접안, 정박 또는 견인에 이용되는 예인장치의 계선줄(견인로프 혹은 체인)을 안내하는 가이드부재이다.In general, a fairlead is a guide member that is installed on all of the bow, stern, and side of a ship and guides the mooring line (towing rope or chain) of a towing device used for berthing, anchoring, or towing of the ship.
그리고, 계선줄은 건현갑판상에 설치되는 견인장치 혹은 접안장치로부터 이어져 예인선과 연결되거나 혹은 항구나 터미널에 고정 설치된 원통말뚝 형태의 고정부과 연결되는 상태를 취하게 된다.In addition, the mooring line is connected to the tugboat by connecting from the towing device or the berthing device installed on the freeboard deck, or it is connected to a cylindrical pile-type fixing part fixedly installed in a port or terminal.
이러한 페어리드와 관련된 기술로는 공개특허 제2009-0105101호, 등록특허제1185399호, 공개실용 제2014-0006023호 등이 개시되어 있다.As techniques related to such fairleads, Korean Patent Publication No. 2009-0105101, Registration Patent No. 1185399, and Publication No. 2014-0006023 are disclosed.
한편, 통상적인 페어리드는 초크 형태인데, 이와 같은 초크는 주로 주물로 제작되기 때문에 표면이 매끄럽지 못하여 마찰시 견인로프의 극심한 손상을 초래하고, 또 초크 자체에 도포된 페인트가 벗겨지면서 녹 등에 의한 수명 단축도 초래하는 단점이 있다.On the other hand, a typical fairlead is in the form of a choke.Since such a choke is mainly made of castings, the surface is not smooth, causing extreme damage to the traction rope during friction.Also, the paint applied to the choke itself peels off, reducing the lifespan due to rust. There is also a drawback that causes it.
이에, 이러한 단점을 해결하기 위한 방안으로 하기한 [선행기술문헌]에서와 같은 초크라이너를 초크에 내장하여 견인로프, 즉 무링로프의 손상을 방지한 예가 있다.Accordingly, as a solution to this disadvantage, there is an example of preventing damage to a traction rope, that is, a mooring rope by embedding a choke liner as in the following [prior art literature] in a choke.
뿐만 아니라, 통상 초크는 앞서 설명한 것처럼 주물로 제작하여 가공을 하지 않으므로 치수 및 표면이 균일하지 않다.In addition, as described above, a typical choke is made of a casting and is not processed, so its dimensions and surfaces are not uniform.
그러므로, 딱딱한 소재의 플라스틱으로 만들어진 초크라이너가 초크에 설치될 때 초크의 표면이 균일하지 않으면 불특정 위치에 빈 공간이 발생하여 이를 메우기 위한 추가 작업이 필요하다.Therefore, when a choke liner made of hard plastic is installed on a choke, if the surface of the choke is not uniform, an empty space is generated at an unspecified location, and additional work is required to fill it.
만약, 초크라이너와 초크 사이의 빈 공간을 방치할 경우에는 로프로부터 힘이 가해지면 초크라이너가 손상될 소지가 많다.If the empty space between the choke liner and the choke is left unattended, the choke liner is likely to be damaged if force is applied from the rope.
그런데, 불특정 위치의 빈 공간을 메우려 하여도 육안으로 확인할 수 없어 현실적으로 어렵다.However, even when trying to fill an empty space at an unspecified location, it is difficult in reality because it cannot be confirmed with the naked eye.
특히, 치수가 맞지 않으면 조립이 되지 않아 수정 가공이 필요하거나 전체적으로 헐거워 초크에 밀착, 고정이 되지 않는 경우도 발생한다.In particular, if the dimensions are not correct, the assembly may not be possible and correction processing may be required, or there may be cases in which it is not closely adhered or fixed to the choke due to the overall looseness.
더구나, 로프에 힘이 걸려 움직일 경우에 딱딱한 소재의 플라스틱 초크라이너 특성상 초크와의 접촉면이 밀착에 의해 발생하는 마찰력이 약하여 이탈하려는 힘이 많이 발생하는 취약점이 있다. 그리고, 전체적으로 헐거울 경우에는 더욱 이탈, 파손의 문제점이 있다.In addition, there is a vulnerability in that the friction force generated by the contact surface with the choke is weak due to the characteristics of a plastic chokeliner made of a hard material when moving due to force applied to the rope, causing a lot of force to escape. And, if it is loose as a whole, there is a problem of separation and damage.
이러한 이유로 딱딱한 소재의 플라스틱 초크라이너는 초크와의 밀착 및 고정 마찰력을 높이기 위한 별도의 본딩 처리 같은 추가 작업이 발생할 수 밖에 없다.For this reason, additional work such as a separate bonding treatment to increase the adhesion and fixed friction of the hard material plastic choke liner is inevitable.
뿐만 아니라, [선행기술문헌]과 같이 딱딱한 소재의 플라스틱 초크라이너의 볼트에 의한 조립 방식은 분할된 한쪽은 반드시 선박의 바깥쪽에서 초크에 삽입됨에 따라 조립, 분해가 어렵고 위험하다.In addition, in the method of assembling by bolts of a plastic chokeliner made of a hard material such as [prior art literature], it is difficult and dangerous to assemble and disassemble as the divided one is necessarily inserted into the choke from the outside of the ship.
또한, 이러한 볼트에 의한 조립방식은 소재의 특성상 손상 방지를 위해 두껍게 제작됨에 따라 두께 및 중량으로 인하여 인력으로 작업하기 어렵다.In addition, the assembly method using such a bolt is made thick to prevent damage due to the nature of the material, so it is difficult to work with manpower due to the thickness and weight.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 초크라이너를 연질의 플라스틱으로 된 일체형으로 구현하여 초크에 결합 사용함으로써 선박 고박용 무링로프를 안전하게 보호하고 장수명화를 달성할 수 있도록 개선된 선박의 무링로프 보호장치를 제공함에 그 주된 목적이 있다.The present invention was created to solve the problems in the prior art as described above. By implementing a chockliner as an integral type made of soft plastic and using it in combination with a choke, it safely protects the no-ring rope for ship anchorage and increases its lifespan.

It provides a device for protecting the no-ring rope of a ship, characterized by.

본 발명은 초크와 초크라이너 공급업체가 다르다는 점, 그리고 초크의 주물제조 특성, 이 모두에 부합하는 초크라이너의 필요성에 의해 창안된 것으로 연질소재의 플라스틱으로 만들어진 초크라이너는 신축성이 좋아 초크의 치수 및 표면이 균일하지 않아도 설치시 밀착이 가능하며 로프에 의한 힘을 받더라도 특유의 신축성에 의해 표면에 밀착되어 빈 공간으로 인한 손상을 방지할 수 있음에 착상된 것이다.The present invention is invented by the difference between the choke and the choke liner supplier, and the need for a choke liner that meets all of the characteristics of the casting production of the choke, and the choke liner made of soft plastic has good elasticity and It is conceived that even if the surface is not uniform, it can be adhered to during installation, and even if it is subjected to force by a rope, it is adhered to the surface by its unique elasticity to prevent damage due to empty spaces.
이 경우, 초크와 접하는 초크라이너 접촉면쪽에 미세한 요철형태의 작은 돌기형상으로 디자인하면 보다 더 마찰에 의한 밀착력을 극대화 할 수 있다.In this case, designing a small protrusion shape in the form of fine irregularities on the contact surface of the choke liner in contact with the choke can further maximize the contact force due to friction.
또한, 연질 소재의 플라스틱 초크라이너는 선박안쪽에서 설치 및 제거가 가능하여 손쉽게 작업이 가능하며 위험하지 않다. 즉, 볼트조립 방식이 아닌 일체형으로 제작되어 두께가 얇고 가벼워 인력으로 쉽게 작업이 가능하다.In addition, the soft material plastic chocliner can be installed and removed from the inside of the ship, so it is easy to work and is not dangerous. In other words, it is manufactured as an integral type rather than a bolt assembly method, so that the thickness is thin and light, so it is possible to work easily with manpower.
도 2 내지 도 4에 도시된 바와 같이, 본 발명에 따른 선박의 무링로프 보호장치는 초크(Chock)(100)를 포함한다.As shown in Figs. 2 to 4, the apparatus for protecting a non-ring rope of a ship according to the present invention includes a choke 100.
이때, 상기 초크(100)는 기존처럼 주물로 제작되며, 새들 형상으로 형성된 내부공간(110)을 구비한다. 물론, 상기 내부공간(110)은 일반적으로 무링로프가 통과하는 공간이다.At this time, the choke 100 is made of a casting as in the past, and has an inner space 110 formed in a saddle shape. Of course, the inner space 110 is generally a space through which the Mourning rope passes.
하지만, 본 발명에서는 상기 내부공간(110)에 초크라이너(Chock Liner)(200)가 끼워진다. 이를 통해, 상기 초크라이너(200)가 무링로프와 초크(100) 사이에 위치되어 무링로프가 주물로 제조된 초크(100) 표면에 직접 접촉되지 않게 함으로써 무링로프의 급마모를 억제하고 장수명화를 유도하게 된다.However, in the present invention, a chock liner 200 is fitted in the inner space 110. Through this, the choke liner 200 is located between the mooring rope and the choke 100 so that the mooring rope does not come into direct contact with the surface of the choke 100 made of a cast, thereby suppressing acute wear of the mooring rope and increasing its lifespan. Induced.
종래에도 초크라이너가 존재하고 있었지만, 종래 초크라이너는 모두 분리형으로 초크(100)를 사이에 두고 앞, 뒤에서 내부공간(110)으로 각각 끼워진 후 내부공(110) 속에서 서로 볼트 체결되는 구조였다.Conventionally, a choke liner has existed, but the conventional choke liners are all detachable and are bolted to each other in the inner hole 110 after being inserted into the inner space 110 from the front and the rear with the choke 100 interposed therebetween.
때문에, 종래 기술에서 언급한 문제들이 파생될 수 밖에 없었지만, 본 발명에서는 상기 초크라이너(200)가 분리형이 아닌 일체형으로 구성된다는 점에서 가장 큰 차이를 갖는다.Therefore, although the problems mentioned in the prior art were inevitably derived, the present invention has the biggest difference in that the chocliner 200 is configured as an integral type rather than a separate type.
특히, 상기 초크라이너(200)는 연질의 합성수지로 성형하여 일체로 성형된후 도 4의 예시와 같이 일단을 구부려 내부공간(110)에 끼워 넣는 방식으로 통과시킨 다음 구부렸던 것을 놔 펼치는 방식으로 쉽게 조립할 수 있다.In particular, the chocliner 200 is formed of a soft synthetic resin and is integrally molded, and then the end is bent and passed through the inner space 110 by inserting it into the inner space 110 as illustrated in FIG. 4, and then the bent one is released and unfolded. Can be assembled.
여기에서, 구부린다는 의미는 일단의 구경을 찌그려뜨려 내부공간(110)에 끼울 수 있는 크기로 갖게 한다는 것을 말한다.Here, the meaning of bend means that a group of apertures are squashed to have a size that can be inserted into the inner space 110.
이것이 가능한 이유는 초크라이너(200)가 연질의 합성수지로 성형되기 때문이며, 무엇보다도 초크라이너(200)의 선단 및 후단에 플랜지(210)가 형성되어 있어 초크(100)의 앞단과 뒷단에 탄성적으로 밀착되기 때문이다.This is possible because the choke liner 200 is molded from a soft synthetic resin, and above all, flanges 210 are formed at the front and rear ends of the choke liner 200 so that the front and rear ends of the choke 100 are elastically Because it adheres closely.
따라서, 본 발명에 따른 초크라이너(200)는 초크(100)의 크기에 맞춰 다양한 크기로 제작될 수 있으며, 경우에 따라서는 도 5의 예시와 같이 길이방향으로 절단선(220)을 따라 절단한 후 절단된 양단을 겹치는 형태로 접어 내부공간(110)에 끼워 넣은 다음 겹치게 접었던 부분을 놓게 되면 외력이 제거되면서 탄성복귀력에 의해 초크라이너(200)가 펴지면서 초크(100)의 내부공간(110)에 밀착되고 절단선(220)들끼리 맞추게 되면 아주 쉬우면서도 완벽한 조립설치가 가능하게 된다.Therefore, the choke liner 200 according to the present invention may be manufactured in various sizes according to the size of the choke 100, and in some cases, cut along the cutting line 220 in the longitudinal direction as in the example of FIG. After the cut ends are folded in an overlapping form and inserted into the inner space 110, and then when the overlapped part is released, the external force is removed and the choke liner 200 is opened by the elastic return force, and the inner space of the choke 100 ( 110) in close contact with the cutting lines 220 to each other, very easy and complete assembly and installation is possible.
이 경우, 절단선(220)은 상측에 배치되게 하여 무링로프가 움직일 때 서로 간섭되지 않도록 함이 바람직하다.In this case, the cutting line 220 is preferably arranged on the upper side so as not to interfere with each other when the mooring rope moves.
덧붙여, 본 발명에서는 상기 초크라이너(200)가 연성을 가지면서도 윤활성을 확보하고, 내마모성을 갖출 수 있도록 PTFE(polytetrafluoroethylene)가 5.5-7.5중량% 함유된 폴리우레탄수지로 성형된 것을 사용함이 바람직하다. 이 경우, 성형품 표면을 불소코팅 처리하면 더욱 좋다.In addition, in the present invention, it is preferable to use a polyurethane resin containing 5.5-7.5% by weight of PTFE (polytetrafluoroethylene) so that the chocliner 200 has ductility while securing lubricity and wear resistance. In this case, it is better to treat the surface of the molded article with fluorine coating.
여기에서, 상기 PTFE 수지는 많은 작은 분자(단위체)들을 사슬이나 그물 형태로 화학결합시켜 만드는 커다란 분자로 이루어진 유기 중합체 계열에 속하는 강하고 질기며 매끄러운 비가연성 수지로서, 폴리우레탄수지에 첨가되어 표면에서의 윤활성을 확보할 뿐만 아니라, -50℃ ~ 350℃ 범위 내에서 점도 변화없이 일관성있는 윤활성을 유지할 수 있도록 하여 준다.Here, the PTFE resin is a strong, tough and smooth non-flammable resin belonging to an organic polymer series consisting of large molecules made by chemically bonding many small molecules (units) in the form of chains or nets, and is added to the polyurethane resin. In addition to securing lubricity, it enables consistent lubrication without viscosity change within the range of -50℃ to 350℃.
또한, 상기 폴리우레탄수지는 베이스수지로서, 기본 성질은 탄성이 풍부하여 신축성이 좋으며 강인하고 질겨 인장파괴강도가 큰 편으로 내마모성, 내노화성, 내유성 등도 뛰어나기 때문에 본 발명의 베이스수지로 적합하다.In addition, the polyurethane resin is a base resin, and its basic properties are rich in elasticity, good elasticity, strong and tough, and have high tensile fracture strength.It is also suitable as the base resin of the present invention because it has excellent wear resistance, aging resistance, and oil resistance.
그리고, 불소 코팅하는 이유는 초크라이너(200)가 연성을 유지하되, 표면에서의 경도를 증가시켜 내마모성을 강화하고, 마찰력을 감소시켜 무링로프의 마모저항성을 줄이기 위함이다.And, the reason for the fluorine coating is to maintain the ductility of the chocliner 200, but to increase the hardness on the surface to enhance abrasion resistance, and to reduce the frictional force to reduce the abrasion resistance of the no-ring rope.
이를 통해, 무링로프의 장수명화를 달성할 수 있게 되며, 반대로 초크라이너(200)의 손상도 현저히 줄어드는 장점을 얻을 수 있게 된다.Through this, it is possible to achieve a longer life of the mooring rope, and conversely, it is possible to obtain the advantage of significantly reducing the damage to the chocliner 200.
도 6은 도 5에 도시된 초크라이너에 형성된 걸림용 돌기 라인을 도시한 도면이다.6 is a view showing a protrusion line for engaging formed in the chocliner shown in FIG.
도 5 및 도 6을 살펴보면, 도 5에서의 초크라이너(200)의 선단 및 후단에 형성된 플랜지(210)는 초크(100)의 앞단과 뒷단에 수직한 방향으로 걸리는 구조를 가진다. 하지만, 도 6에서의 초크라이너(200)의 플랜지는 초크(100)의 뒷단 가장자리를 완전히 감싸는 형상의 걸림용 돌기 라인(230)이 마련된다.5 and 6, the flanges 210 formed at the front and rear ends of the choke liner 200 in FIG. 5 have a structure that is hung in a direction perpendicular to the front and rear ends of the choke 100. However, the flange of the choke liner 200 in FIG. 6 is provided with a protrusion line 230 for engaging a shape that completely surrounds the rear edge of the choke 100.
따라서, 걸림용 돌기 라인(230)이 초크(100)의 뒷단 가장자리를 완전히 감쌈에 따라, 무링로프가 초크라이너(200) 내부를 통해 이동하더라도, 초크라이너(200)가 초크(100)에 안정적으로 밀착 고정될 수 있으며 이탈이 방지될 수 있다.Therefore, as the locking protrusion line 230 completely wraps the rear edge of the choke 100, even if the Mouring rope moves through the inside of the choke liner 200, the choke liner 200 is stably attached to the choke 100 It can be tightly fixed and can be prevented from leaving.
한편, 초크(100)와 초크라이너(200)가 접촉하면 접촉면에는 다수의 마찰 돌기가 형상됨에 따라, 보다 큰 마찰을 통한 밀착력을 극대화할 수 있는데, 이는 도 7을 통해 보다 구체적으로 살펴보기로 한다.On the other hand, when the choke 100 and the choke liner 200 are in contact, as a plurality of friction protrusions are formed on the contact surface, adhesion through greater friction can be maximized, which will be described in more detail with reference to FIG. 7. .
도 7은 도 5에 도시된 초크라이너의 외측면에 형성된 다수 개의 마찰 돌기를 도시한 도면이다.7 is a view showing a plurality of friction protrusions formed on the outer surface of the chocliner shown in FIG.
도 7을 살펴보면, 초크라이너(200)의 외측면 중에서 초크와 접촉되는 영역에는 일정한 간격으로 하나 이상의 마찰 돌기(200a)가 형성된다. 이를 통해, 일정한 간격으로 돌출 형성된 마찰 돌기(200a)에 의한 마찰을 통해 초크와의 밀착력을 극대화 할 수 있다.Referring to FIG. 7, one or more friction protrusions 200a are formed at regular intervals in a region of the outer surface of the choke liner 200 in contact with the choke. Through this, the adhesion with the choke can be maximized through friction by the friction protrusions 200a protruding at regular intervals.
또한, 본 발명의 일 실시예에서는 초크라이너(200)를 초크(100)에 고정로프를 이용하여 보다 강하게 고정시킬 수 있는 방법을 제안한다. 이에 관해서는 도 8을 통해 보다 구체적으로 살펴보기로 한다.In addition, an embodiment of the present invention proposes a method of more strongly fixing the choke liner 200 to the choke 100 by using a fixing rope. This will be described in more detail with reference to FIG. 8.
도 8은 도 5에 도시된 초크라이너에 타공된 다수 개의 관통홀과, 로정로프에 의해 초크라이너가 초크에 결박 및 고정된 상태를 도시한 도면이다.FIG. 8 is a diagram illustrating a state in which the choke liner is bound and fixed to the choke by a plurality of through holes perforated in the choke liner shown in FIG. 5 and a rope rope.
도 8을 살펴보면, 본 발명의 초크라이너(200)의 양측 플랜지(210)에는 각각 초크(100)의 길이방향을 향하는 다수 개의 관통홀(200b)이 타공된다.Referring to FIG. 8, a plurality of through holes 200b facing the longitudinal direction of the choke 100 are perforated in both flanges 210 of the choke liner 200 of the present invention.
이때, 양측 플랜지(210) 각각에 타공되는 관통홀(200b)들은 서로 대칭을 이루게 되는데, 초크라이너(200)가 초크(100)의 내부공간에 설치된 상태에서 다수 개의 관통홀(200b) 각각에 고정로프(200c)가 관통하여 묶이는 경우, 초크라이너(200)는 초크(100)에 완전히 결박된다. 따라서, 무링로프가 초크라이너(200) 내부면과 강하게 마찰되면서 움직이더라도, 초크라이너(200)는 고정로프(200c)의 결박력에 의해 초크(100)에 강하게 결박 및 고정될 수 있다.At this time, the through-holes 200b perforated in each of the flanges 210 are symmetrical to each other, and the choke liner 200 is fixed to each of the plurality of through-holes 200b while being installed in the inner space of the choke 100 When the rope 200c penetrates and is bound, the choke liner 200 is completely bound to the choke 100. Therefore, even if the Mooring rope moves while being strongly rubbed against the inner surface of the chocliner 200, the chocliner 200 may be strongly bound and fixed to the choke 100 by the binding force of the fixed rope 200c.
