탄성체(150)는 샤클 핀(120)의 외주면에 삽입되어 샤클 핀(120)이 제1 홀(113)에 체결될 때 샤클 핀(120)에 삽입 반대 방향으로 탄성력을 발생시켜 샤클 핀(120)이 제1, 2 홀(113, 116)에서 풀리는 현상을 방지하게 된다.The elastic body 150 is inserted into the outer circumferential surface of the shackle pin 120 to generate an elastic force in the opposite direction of insertion into the shackle pin 120 when the shackle pin 120 is fastened to the first hole 113 to generate the shackle pin 120 The first and second holes 113 and 116 are prevented from being loosened.
즉, 탄성체(150)는 샤클 핀(120)의 제1, 2 나선돌기(122a, 122b)가 샤클 몸체(110)의 일단부(112)와 타단부(115)에 형성된 제1, 2 홀(113, 116) 내의 제1, 2 나선홈(113a, 116a)에 체결될 때 샤클 핀(120)에 샤클 핀의 삽입 반대 방향으로 탄성력을 발생시켜 샤클 핀(120)의 풀림을 방지하게 한다.That is, in the elastic body 150, the first and second spiral protrusions 122a and 122b of the shackle pin 120 are formed in one end 112 and the other end 115 of the shackle body 110, and the first and second holes ( When fastened to the first and second spiral grooves 113a and 116a in the 113 and 116, an elastic force is generated in the direction opposite to the insertion of the shackle pin 120 to prevent the shackle pin 120 from loosening.
그러므로 본 발명의 제1 실시예에 따른 샤클(100)은 샤클 몸체(110)에 형성된 인양 고리(111)의 상면에 보조 인양 고리(111a)가 부가 형성되어, 강도 보강과 함께 인양 고리(111)의 양단부가 안쪽 방향으로 변형됨을 방지하고, 인양 고리(111)와 보조 인양 고리(111a)의 다수 지점에 로프가 접한 상태로 연결하므로 샤클(100)의 앞뒤 흔들림을 최소화한다.Therefore, in the shackle 100 according to the first embodiment of the present invention, an auxiliary lifting ring 111a is additionally formed on the upper surface of the lifting ring 111 formed on the shackle body 110, and the lifting ring 111 with strength reinforcement It prevents the deformation of both ends of the inward direction, and minimizes the back and forth shaking of the shackle 100 because the rope is connected in contact with a plurality of points of the lifting ring 111 and the auxiliary lifting ring 111a.
더욱이, 샤클 핀(120)의 손잡이(124)에 형성된 제1 결속홀(124a)에 잠금부재(130)를 구비하고, 제2 결속홀(124c)에 풀림방지부재(140)를 구비하여 샤클 핀(120)의 분리를 이중으로 방지하게 된다.In addition, a locking member 130 is provided in the first binding hole 124a formed in the handle 124 of the shackle pin 120, and a loosening preventing member 140 is provided in the second binding hole 124c. It will prevent the separation of 120 double.
즉, 샤클 핀(120)의 회전에 의해 샤클 몸체(110)의 제1, 2 홀(113, 116)에 체결하여 제2 결속부(142)의 단부가 일단부(112)에 형성된 결속홈(114) 내에 위치되기 시작하면 샤클 핀(120)이 회전되지 못하다가, 샤클 핀(120)을 힘을 가해 더 회전시키면 제2 결속부(142)가 결속홈(114)에서 벗어나면서 어느 하나의 결속홈(114)과 다른 하나의 결속홈(114)만큼 샤클 핀(120)의 회전이 가능해지고, 제2 결속부(142)의 단부가 일단부(112)에 형성된 결속홈(114) 내에 위치되기 시작하면 샤클 핀(120)이 회전되지 못하게 되는 과정을 반복하게 된다.That is, by the rotation of the shackle pin 120, it is fastened to the first and second holes 113 and 116 of the shackle body 110 so that the end of the second binding portion 142 is formed on the one end 112. 114), the shackle pin 120 cannot be rotated, but when the shackle pin 120 is rotated further by applying a force, the second binding portion 142 is removed from the binding groove 114 and any one of them is bound. The shackle pin 120 can be rotated as much as the groove 114 and the other binding groove 114, and the end of the second binding portion 142 is located in the binding groove 114 formed at one end 112 When starting, the process of preventing the shackle pin 120 from rotating is repeated.
더욱이, 샤클 핀(120)을 완전 회전시켜 제1 결속부(132)의 단부가 일단부(112) 내에 위치되는 시점에 사용자가 파지회전부(136)를 회전시키면 잠금부재(130) 단부의 제1 결속부(132)가 결속홈(114)의 내부까지 전진하게 되면서 샤클 핀(120)이 회전되지 못하도록 회전을 제한하게 된다.Moreover, when the user rotates the gripping rotation part 136 at the time when the shackle pin 120 is completely rotated so that the end of the first binding part 132 is located within the one end 112, the first end of the locking member 130 As the binding portion 132 advances to the inside of the binding groove 114, rotation is restricted so that the shackle pin 120 cannot rotate.
도 6 내지 도 9를 참조하면, 본 발명의 제2 실시예에 따른 잠금장치를 구비한 샤클(200)은 샤클 몸체(210), 샤클 핀(220) 및 잠금부재(230)를 포함하며, 잠금부재(230)는 앞선 실시예의 그것과 동일한 구조와 기능을 하므로 상세한 설명은 생략한다.6 to 9, a shackle 200 having a locking device according to a second embodiment of the present invention includes a shackle body 210, a shackle pin 220 and a locking member 230, and locks Since the member 230 has the same structure and function as that of the previous embodiment, a detailed description will be omitted.
샤클 몸체(210)는 도 6 내지 도 8에 도시된 바와 같이 주물 등을 통해 성형되되, 피인양체가 연결되는 하단이 개방되어 형성된 일단부(212)와 타단부(215)의 사이에 후술할 샤클 핀(220)이 체결되도록 동일 수평선상에 제1, 2 홀(213, 216)이 각각 관통 형성되고, 크레인의 후크가 연결되는 상단이 폐쇄되면서 인양 고리(211)를 형성한다.The shackle body 210 is molded through a casting, as shown in FIGS. 6 to 8, but a shackle to be described later between one end 212 and the other end 215 formed by opening the lower end to which the object to be lifted is connected The first and second holes 213 and 216 are respectively formed through the same horizontal line so that the pin 220 is fastened, and the upper end to which the hook of the crane is connected is closed to form a lifting ring 211.
이때, 일단부(212)와 타단부(215)는 피인양체에 연결되는 연결고리 또는 로프 등을 샤클 몸체(210)의 내부로 진입시킬 수 있도록 하단을 개방시키게 된다.At this time, one end 212 and the other end 215 open the lower end so that a connection ring or a rope connected to the object to be lifted can enter the inside of the shackle body 210.
그리고 샤클 몸체(210)의 일단부(212)와 타단부(215) 중 일단부(212)에 형성된 제1 홀(213)의 내주면에는 나선돌기가 형성되지 않고, 타단부(215)에 형성된 제2 홀(216)의 내주면에는 샤클 핀(220)의 선단에 형성된 나선돌기(222a)가 나선 체결되도록 나선홈(216a)이 형성된다.In addition, a spiral protrusion is not formed on the inner circumferential surface of the first hole 213 formed at one end 212 of the one end 212 and the other end 215 of the shackle body 210, and is formed at the other end 215. 2 A spiral groove 216a is formed on the inner circumferential surface of the hole 216 so that the spiral protrusion 222a formed at the tip of the shackle pin 220 is spirally fastened.
한편, 도면에는 도시하지 않았지만, 제1 홀(213)의 내주면 일측에 홈을 형성하고, 홈 내에 "U"자 형상의 탄성부가 구비되고, 샤클 몸체(210)의 제1, 2 홀(213, 216)에 샤클 핀(220)이 거의 고정될 때 탄성부의 정점 부위가 위치되도록 샤클 핀(220)의 나선돌기(222a) 반대측 몸체(222) 외주면을 따라 방사상의 산형부가 구비되어 샤클 핀(220)을 강제 회전시켜야만 탄성부가 산형부를 넘어가면서 샤클 핀(220)이 회전될 수 있도록 한다. On the other hand, although not shown in the drawing, a groove is formed on one side of the inner circumferential surface of the first hole 213, a "U"-shaped elastic part is provided in the groove, and the first and second holes 213 of the shackle body 210 The shackle pin 220 is provided with a radial angular portion along the outer peripheral surface of the body 222 opposite the spiral protrusion 222a of the shackle pin 220 so that the apex of the elastic portion is located when the shackle pin 220 is almost fixed to the shackle pin 220 The shackle pin 220 can be rotated while the elastic portion crosses the mountain-shaped portion only to be rotated forcibly.
더욱이, 샤클 몸체(210)의 일단부(212)와 타단부(215) 중 샤클 핀(220)의 선단이 먼저 삽입되는 일단부(212)는 앞선 실시예에서와 같이 정면에서 봤을 때 타단부(215)에 비해 단면적이 크도록 확장 형성된다. Moreover, one end 212 of the shackle body 210 and the other end 215 of the shackle pin 220 into which the tip of the shackle pin 220 is first inserted is the other end when viewed from the front as in the previous embodiment ( 215) is formed to expand so that the cross-sectional area is larger.
그리고 일단부(212)의 제1 홀(213) 바깥쪽 가장자리를 따라 면취면(213a)이 함몰 형성된다.In addition, a chamfered surface 213a is formed along the outer edge of the first hole 213 of the one end 212.
또한, 샤클 몸체(210)의 일단부(212) 측면에 제1 홀(213)의 주위를 따라 방사상의 결속홈(214)이 형성된다. 이때, 결속홈(214)은 반구 형상으로 함몰 형성되어 후술할 잠금부재(230)의 제1 결속부(232)의 단부가 결속 또는 분리되게 한다.In addition, a radial binding groove 214 is formed along the periphery of the first hole 213 on the side of the one end 212 of the shackle body 210. At this time, the binding groove 214 is formed in a hemispherical shape so that the end of the first binding portion 232 of the locking member 230 to be described later is bound or separated.
샤클 핀(220)은 도 6 내지 도 8에 도시된 바와 같이 주물 등으로 성형된 상태에서 기계 가공에 의해 선 외주면에 나선돌기(222a)를 형성하며, 샤클 몸체(210)의 일단부(212)와 타단부(215)에 형성된 제1, 2 홀(213, 216)에 체결되어 인양될 피인양체의 인양 고리 또는 피인양체와 연결되는 와이어 등이 결속되게 하는 구성으로, 몸체(222), 나선돌기(222) 및 손잡이(224)를 포함한다.The shackle pin 220 forms a spiral protrusion 222a on the outer circumferential surface of the line by machining in a state molded into a casting, as shown in FIGS. 6 to 8, and one end 212 of the shackle body 210 It is fastened to the first and second holes 213 and 216 formed in the other end 215 to bind the lifting ring of the lifting object to be lifted or the wire connected to the lifting object, and the body 222, It includes a spiral protrusion 222 and a handle 224.
몸체(222)는 기계 가공에 의해 나선돌기(222a)의 외경보다 작은 외경을 갖도록 형성된다.The body 222 is formed to have an outer diameter smaller than the outer diameter of the spiral protrusion 222a by machining.
나선돌기(222a)는 샤클 몸체(210) 타단부(215)의 제2 홀(216)에 형성된 나선홈(216a)에 나선 체결될 수 있도록 몸체(222)의 전방에 형성된다.The spiral protrusion 222a is formed in front of the body 222 so as to be helically fastened to the spiral groove 216a formed in the second hole 216 of the other end portion 215 of the shackle body 210.
이때, 나선돌기(222a)는 앞선 실시예와 다르게 샤클 몸체(210)의 몸체(222) 전방에만 형성된다.At this time, the spiral protrusion (222a) is formed only in front of the body 222 of the shackle body 210, unlike the previous embodiment.
그리고 몸체(222)와 손잡이(224)와의 경계면에 경사면(223)이 돌출 형성된다. 이때, 경사면(223)은 샤클 몸체(210)의 제1, 2 홀(213, 216)에 샤클 핀(220)을 체결할 때 샤클 몸체(210) 일단부(212)의 제1 홀(213) 입구에 형성된 면취면(213a)에 밀착되면서 샤클 핀(220)의 삽입 방향을 안내 받게 된다.In addition, an inclined surface 223 protrudes on the interface between the body 222 and the handle 224. At this time, the inclined surface 223 is the first hole 213 of the shackle body 210 and one end 212 when the shackle pin 220 is fastened to the first and second holes 213 and 216 of the shackle body 210 While in close contact with the chamfered surface 213a formed at the entrance, the insertion direction of the shackle pin 220 is guided.
즉, 샤클 몸체(210)의 제1, 2 홀(213, 216)에 샤클 핀(220)을 체결할 때 경사면(223)이 제1, 2 홀(213, 216) 중심에 샤클 핀(220)의 중심이 일치하도록 하면서 샤클 핀(220)의 흔들림을 방지하게 된다. 이는 샤클 핀(220)의 나선돌기(222a)에 의해서만 샤클 몸체(210)의 나선홈(216a)에 한 지점만 체결되므로 샤클 핀(220)에 흔들림이 발생하기 때문이다.That is, when the shackle pin 220 is fastened to the first and second holes 213 and 216 of the shackle body 210, the inclined surface 223 is positioned at the center of the first and second holes 213 and 216. The center of the shackle pin 220 is prevented from shaking while being aligned. This is because only one point is fastened to the helical groove 216a of the shackle body 210 by the helical protrusion 222a of the shackle pin 220, so shaking occurs in the shackle pin 220.
손잡이(224)는 몸체(222)의 후방과 이웃하게 연장되면서 샤클 몸체(210)의 일단부(212) 외측으로 노출되도록 형성되며, 타단부(215)에 형성된 제2 홀(216)의 나선홈(216)에 샤클 핀(220)을 체결시킬 때 작업자가 손으로 파지할 수 있도록 한다.The handle 224 is formed to be exposed to the outside of the one end 212 of the shackle body 210 while extending adjacent to the rear of the body 222, and a spiral groove of the second hole 216 formed at the other end 215 When the shackle pin 220 is fastened to 216, the operator can grip it by hand.
한편, 손잡이(224) 중 일측에 잠금부재(230)가 설치되도록 제1 결속홀(224a)이 형성되고, 제1 결속홀(224a)의 이격된 양측에 잠금부재(230)의 이탈을 방지하는 이탈방지 브래킷(231)의 고정을 위한 나사(231a)가 체결되도록 체결홀(224b)이 각각 형성된다.On the other hand, a first binding hole (224a) is formed so that the locking member 230 is installed on one side of the handle 224, and to prevent the separation of the locking member 230 on both sides spaced apart from the first binding hole (224a). Fastening holes 224b are formed so that the screws 231a for fixing the separation prevention bracket 231 are fastened.
잠금부재(230)는 도 6 및 도 9에 도시된 바와 같이 샤클 핀(220)의 손잡이(224) 일측에 형성된 제1 결속홀(224a)에 설치되어 샤클 몸체(210)의 일단부(212)에 방사상으로 형성된 복수의 결속홈(214) 중 어느 하나의 홈에 결속되어 이동되면서 샤클 핀(220)을 잠금 또는 잠금 해제시키는 기능을 하며, 제1 결속부(232), 나선체결돌기(234), 파지회전부(236) 및 제1 탄성부(238)를 포함한다.The locking member 230 is installed in the first binding hole 224a formed on one side of the handle 224 of the shackle pin 220, as shown in FIGS. 6 and 9, and the one end 212 of the shackle body 210 A function of locking or unlocking the shackle pin 220 as it is bound to any one of the plurality of binding grooves 214 formed radially in the groove 214, and the first binding portion 232, the spiral fastening protrusion 234 , And a gripping rotation part 236 and a first elastic part 238.
이때, 제1 결속부(232), 나선체결돌기(234), 파지회전부(236) 및 제1 탄성부(238)는 앞선 실시예의 그것과 동일한 구조와 기능을 하므로 상세한 설명은 생략한다. At this time, the first binding portion 232, the spiral fastening protrusion 234, the gripping rotation portion 236, and the first elastic portion 238 have the same structure and function as those of the previous embodiment, so a detailed description thereof will be omitted.
또한, 잠금부재(230)는 이탈방지 브래킷(231)에 의해 제1 결홈홀(224a) 내에서만 이동 가능하도록 구비된다. 즉, 이탈방지 브래킷(231)은 나선체결돌기(234)와 파지회전부(236)의 사이에 형성된 단차홈이 걸리도록 일측이 개구된 홈이 형성되며, 양쪽 홀을 통해 스프링 와셔(231b)가 장착된 나사(231a)가 체결홀(224b)에 각각 체결된다.In addition, the locking member 230 is provided to be movable only within the first groove hole (224a) by the separation prevention bracket 231. That is, the separation prevention bracket 231 is formed with a groove with one side open so that a step groove formed between the spiral fastening protrusion 234 and the gripping rotation unit 236 is caught, and a spring washer 231b is mounted through both holes The screws 231a are respectively fastened to the fastening holes 224b.
그러므로 본 발명의 제2 실시예에 따른 샤클(200)은 샤클 몸체(210)에 형성된 인양 고리(211)에 로프를 고정시킨 후 크레인의 후크와 피인양체를 상호 연결하게 된다.Therefore, in the shackle 200 according to the second embodiment of the present invention, after fixing the rope to the lifting ring 211 formed on the shackle body 210, the hook of the crane and the lifted body are interconnected.
더욱이, 샤클 핀(220)을 완전 회전시켜 제1 결속부(232)의 단부가 일단부(212) 내에 위치되는 시점에 사용자가 파지회전부(236)를 회전시키면 잠금부재(230) 단부의 제1 결속부(232)가 결속홈(214)의 내부까지 전진하게 되면서 샤클 핀(220)이 회전되지 못하도록 한다.Moreover, when the user rotates the gripping rotation part 236 at the time when the shackle pin 220 is completely rotated so that the end of the first binding part 232 is located within the one end 212, the first end of the locking member 230 As the binding portion 232 advances to the inside of the binding groove 214, the shackle pin 220 is prevented from rotating.
그리고 몸체(222)와 손잡이(224)와의 경계면에 형성된 경사면(223)은 샤클 몸체(210)의 제1, 2 홀(213, 216)에 샤클 핀(220)을 체결할 때 샤클 몸체(210) 일단부(212)의 제1 홀(213) 입구에 형성된 면취면(213a)에 밀착되면서 샤클 핀(220)의 삽입 방향 안내와 함께 샤클 핀(220)의 흔들림을 방지하게 된다.And the inclined surface 223 formed on the interface between the body 222 and the handle 224 is the shackle body 210 when the shackle pin 220 is fastened to the first and second holes 213 and 216 of the shackle body 210 While being in close contact with the chamfered surface 213a formed at the entrance of the first hole 213 of the one end 212, the shackle pin 220 is prevented from shaking together with guidance in the insertion direction of the shackle pin 220.
