Abstract

본 고안은 크레인용 걸고리에 관한것으로서 더욱 구체적으로는 안전쇠(4)의 작동을 작동편(5)의 손잡이부(501)에 의거하여 걸고리본체(1)외측에서 실시할수 있도로 하여 걸부(101)에서 운반줄(도시하지 않음))을 인위적으로 이탈시키고자 할 때 손가락 협착과 같은 안전사고를 예방할수 있게하고 또 일정한 각도로 기울어지는 작동편(5)자중에 의해 안전쇠(4)의 걸공(102) 잠금위치가 견고하게 유지되도록 하여 자연적인 운반줄의 이탈이 방지되도록 하며 그리고 고장의 염려가 없는 안전쇠(4)를 얻을수 있도록 함과 동시에 유지 및 보수도 용이한 안전쇠(4)를 얻을수 있도록 한 것이다.The present invention relates to a hook for a crane, and more specifically, the hook 101 may be operated on the outside of the hook body 1 based on the handle part 501 of the operating piece 5. In order to artificially separate the carrying line (not shown)), it is possible to prevent safety accidents such as stenosis and to secure the safety catches 4 by the weight of the operating piece 5 which is inclined at an angle. (102) The locking position is maintained firmly to prevent the departure of the natural transport line and to obtain a safety catch (4) without the risk of failure, and at the same time the safety catch (4) easy to maintain and repair To get it.

즉, 걸고리본체(1)의 걸공(102)상부에 안전쇠(4)를 회동가능케 장치하는 것에 있어서, 안전쇠(4)를 세로로 배치하여 그 상측의 회동부(401)를 걸고리본체(1)의 연장부(2)내측에 형성되는 지지부(201)와 회동지지핀(6)으로 연결하고 회동부(401)의 일측으로는 외측단의 손잡이부(501)가 걸고리본체(1)외측까지 연장되는 작동편(5)을 일체로 형성하되, 손잡이부(501)상측에 제한판(502)을 형성하여 걸고리본체(1)외측 상면에 접촉되도록 하여서된 것이다.That is, when the safety catch 4 is rotatable on the hook hole 102 of the hook body 1, the safety catch 4 is arranged vertically and the hook body 401 on the upper side of the hook body 1 is hooked. The support part 201 formed in the extension part 2 of the inner side and the rotation support pin 6 are connected, and the handle part 501 of the outer end is hooked to one side of the rotation part 401 to the outside of the hook body 1. The operating piece 5 extends integrally, but the limiting plate 502 is formed on the handle portion 501 so as to be in contact with the upper surface of the hook body 1.

Description

크레인용 걸고리{HOOK FOR CRANE}Hook for crane {HOOK FOR CRANE}

본 고안은 중량물을 크레인을 이용하여 운반할 때 중량물의 로프나 와이어('이하 운반줄이라고 함')가 걸려지는 걸고리를 개량 한것으로서 이를 좀더 구체적으로 설명하자면 걸부의 걸공에 도입되는 운반줄의 이탈을 방지하는 안전쇠 해지를 걸고리본체 외부에서 실시할수 있도록 함과 동시에 원상복귀(걸공 잠금)는 안전쇠의 자중(自重)으로 이루어지도록 하므로서 보다 안전하게 중량물의 운반줄을 걸고리본체에 걸고 이탈시킬수 있도록 한것이다.The present invention improves the hook that heavy ropes or wires (hereinafter referred to as "carrying strings") hang when carrying heavy weights by using a crane. Hanging the safety catch to prevent the hook from being carried out from the outside of the main body and at the same time the original return (locking lock) is made by the weight of the safety iron, so that it is possible to hang the transport line of the heavy goods to the hook body and detach it more safely. All.

일반적인 걸고리의 안전쇠는 걸공 도입하는 운반줄의 이탈을 방지하는 목적에만 부합하도록 장치되어 있으므로 즉, 걸공 상부에 안전쇠를 하향 회동가능케 장치한 후 이를 스프링으로 탄설시켰으므로 걸공에서 운반줄을 인위적으로 이탈시키고자 할 때에는 사람의 손가락으로 안전쇠를 직접 하향 작동시켜야 하고 또 운반줄이 완전하게 이탈될 때 까지 계속 안전쇠를 누루고 있어야 하기 때문에 운반줄의 이탈작업에 많은 불편이 있었으며 또한 안전쇠의 하향작동을 유지시키는 손가락이 걸공 내부에 위치되므로 이탈되는 운반줄과 안전쇠 사이에 손가락이 협착되는 안전사고도 빈번하게 발생되었고 이러한 안전사고의 위험을 피하기 위해 작업장에서는 안전쇠 기능을 제거하게 되는데 이는 중대한 재해(중량물 낙하)를 유발시켰으며 그리고 반복적인 작동으로 인하여 안전쇠를 지지하는 스프링의 장력이 약화 될 경우에는 이 또한 중대한 재해를 유발시키는 원인이 되어왔다.Since the safety catch of the general hook is designed to meet the purpose of preventing the detachment of the transport line to be introduced into the hook, that is, the safety lock is installed on the upper part of the hook so that it can be rotated down and it is installed with a spring. In order to do this, the safety catch has to be operated with the finger of a person directly and the safety catch has to be held down until the transport line is completely detached. Since the finger holding the clamp is located inside the gongong, safety accidents are frequently occurred between the dismantled transport line and the safety catch, and the safety catch function is removed from the workplace to avoid the risk of such a safety accident. (Heavy weight drop) and repeated If due to work weakens the tension of the spring supporting the safety hinges it has also been the cause of that cause great disaster.

본 고안은 상기에서 설명한 바와 같은 폐단들을 한꺼번에 해결하기 위하여 운반줄의 인위적인 이탈을 편리하고 안전하게 실시할수 있음과 동시에 안전쇠의 작동이 처음과 같이 항상 유지되는 걸고리를 안출한 것인데 이를 첨부된 도면과 함께 더욱 상세히 설명하면 다음과 같다.The present invention is a convenient and safe implementation of the artificial separation of the transport line in order to solve the above-mentioned closures at once, and at the same time to create a hook that the operation of the safety lock is always maintained as the first time with the accompanying drawings More detailed description is as follows.

걸고리본체(1)의 걸공(102)상부에 안전쇠(4)를 회동가능케 장치하는 것에 있어서, 안전쇠(4)를 세로로 배치하여 그 상측의 회동부(401)를 걸고리본체(1)의 연장부(2)내측에 형성되는 지지부(201)와 회동지지핀(6)으로 연결하고 회동부(401)의 일측으로는 외측단의 손잡이부(501)가 걸고리본체(1)외측까지 연장되는 작동편(5)을 일체로 형성하되, 손잡이부(501)상측에 제한판(502)을 형성하여 걸고리본체(1)외측 상면에 접촉되도록 하므로서 작동편(5)이 일정한 각도로 기울어지도록 하여서된 것이다.In arranging the safety latch 4 on the hook hole 102 of the hook body 1 so that the safety latch 4 can be rotated, the safety latch 4 is arranged vertically and the upper pivot portion 401 of the hook body 1 of the hook body 1 is rotated. The support part 201 formed in the extension part 2 and the pivot support pin 6 are connected to each other, and the handle part 501 of the outer end is extended to the hook body 1 outside to one side of the pivot part 401. The operating piece 5 is integrally formed, but the limiting plate 502 is formed on the handle part 501 so that the operating piece 5 is inclined at a predetermined angle so as to be in contact with the upper surface of the hook body 1. will be.

이와같이 된 본 고안은 세로로 배치되는 안전쇠(4)의 회동부(401)일측으로 손잡이부(501)를 가진 작동편(5)이 걸고리본체(1)외측까지 일체로 연장되므로 안전쇠(4)에 직접 힘을 가하지 않아도 첨부도면 도 3에서와 같이 작동편(5)의 손잡이부(501)를 위로 올리면 안전쇠(4)가 회동부(401)의 회동지지핀(6)을 중심으로 하여 외측으로 회동하기 때문에 걸공(102)을 개방(해지)시킬수 있게되며 반대로 잡고있는 손잡이부(501)를 놓으면 작동편(5)이 자중에 의해 낙하하면서 안전쇠(4)를 원상복귀(걸공 잠금)시키게 되는데 이때 작동편(5)과 안전쇠(4)의 회동중심점이 안전쇠(4)쪽으로 편중되어 있어 작동편(5)의 자중 낙하가 원할하게 이루어지며 이렇게 낙하하는 작동편(5)은 손잡이부(501)상측에 형성된 제한판(502)이 걸고리본체 (1)외측 상면에 접촉 되므로서 낙하가 정지되게 되며 그리고 회동부(401)가 제한판(502)이 접촉되는 걸고리본체(1)외측 상면 보다 높은 위치에 구성되어 있으므로 평상시에는 작동편(5)이 기울어 지게되어 작동편(5)의 자연적인 상향 작동이 불 가능 할 뿐만 아니라 보다 원할한 작동편(5)의 자중낙하가 도모되게된다.The present invention as described above is the operating piece (5) having the handle portion 501 to one side of the pivoting portion 401 of the safety latch (4) arranged vertically extends integrally to the hook body (1) outside the safety latch (4) Even if a force is not applied directly to the drawing, as shown in FIG. 3, when the handle part 501 of the operating piece 5 is lifted up, the safety catch 4 is centered on the pivot support pin 6 of the pivoting part 401. Because it rotates outward, the hook 102 can be opened (released) and vice versa. When the handle portion 501 is held, the operating piece 5 falls by its own weight, thereby restoring the safety catch 4 to its original position (locking lock). At this time, the pivot point of the operating piece 5 and the safety catch 4 is It is biased toward the safety lock (4), so that the falling of the weight of the operation piece 5 is made smoothly, the operation piece (5) falling in this way is the limit plate 502 formed on the handle portion 501, hook body (1) Falling is stopped by being in contact with the outer upper surface, and since the rotating part 401 is configured at a position higher than the upper surface of the hook body 1 outside the limiting plate 502, the working piece 5 is inclined at ordinary times. Thus, the natural upward actuation of the actuating piece 5 is not only possible, but also a more smooth fall of the actuating piece 5 is achieved.

따라서 본 발명은 상기한 바와 같이 안전쇠(4)의 작동을 작동편(5)의 손잡이부(501)에 의거하여 걸고리본체(1)외측에서 실시할수 있으므로 걸부(101)에서 운반줄(7)을 인위적으로 이탈시키고자 할 때 손가락 협착과 같은 안전사고를 예방할수 있는 이점이 있고 또 일정한 각도로 기울어지는 작동편(5)자중에 의해 안전쇠(4)의 걸공(102) 잠금위치가 견고하게 유지되므로 자연적인 운반줄(7)의 이탈이 방지되며 뿐만 아니라 안전쇠(4)를 장치함에 있어 스프링과 같은 별도의 부재가 필요하지 않아 고장의 염려가 거의 없음은 물론 유지 및 보수도 용이한 이점도 있게 되는 것이다.Therefore, the present invention can be carried out on the hook body (1) outside the hook body (501) on the basis of the handle portion 501 of the operating piece (5) as described above, so that the carrying line (7) in the hook portion (101) In order to artificially disengage, there is an advantage that can prevent safety accidents such as stenosis, and the locking position of the fastener 102 of the safety catch 4 is firmly secured by the weight of the operating piece 5 inclined at an angle. Since it is maintained, the natural separation of the transport line 7 is prevented, and in addition, there is no need for a separate member such as a spring in installing the safety catch 4 so that there is almost no risk of failure as well as easy maintenance and repair. Will be.
