질소 냉각박스 커버 개폐장치{Apparatus for open and close cover of nitrogen cooling box}Apparatus for open and close cover of nitrogen cooling box}

본 고안은 질소 냉각박스 피팅(fitting)용 커버 개폐장치에 관한 것으로서, 더욱 상세하게는 선박의 건조 작업장에서 이용되는 질소 냉각박스의 커버가 무거워 발생될수 있는 안전사고를 방지할 수 있도록 커버에 무게추를 달아 작업자 혼자서 쉽게 열고 닫을 수 있도록 한 질소 냉각박스 커버 개폐장치에 관한 것이다.
The present invention relates to a cover opening and closing device for nitrogen cooling box fitting (fitting), more specifically, the weight of the cover to prevent the safety accident that may occur due to the heavy cover of the nitrogen cooling box used in the ship's drying workshop It relates to a nitrogen cooling box cover opening and closing device so that the worker can easily open and close by himself.

일반적으로 선박의 건조공정에서 부시와 같은 부품은 수축조립을 하게 된다. 수축조립을 하기 위해서는 조립 현장에서 해당 부품을 냉각시켜야 하며 이를 위하여 질소 냉각 박스가 이용된다.In general, parts such as bushes are shrink-assembled in the shipbuilding process. Shrink assembly requires the parts to be cooled at the assembly site and a nitrogen cooling box is used for this purpose.

도 1은 종래 질소 냉각박스 커버 열림 상태 설명도이고, 도 2는 종래 질소 냉각박스 커버 닫힘 상태 설명도이다.1 is a diagram illustrating a conventional nitrogen cooling box cover open state, and FIG. 2 is a diagram illustrating a conventional nitrogen cooling box cover closed state.

이에 도시된 바와 같이, 질소 냉각박스 몸체(통)(10)에는 힌지장치(30)에 의해 개폐 가능한 커버(20)가 달려 있고, 커버(20)의 중앙부를 통해서 질소 냉각박스 몸체(10) 내부로 질소를 주입 충진하도록 이루어지며, 질소 냉각박스 몸체(10)와 커버(20)에는 서로 쌍을 이루는 잠금장치(40,41)가 설치되며, 커버(20)의 상면에는 복수의 손잡이(21)가 설치되어 구성된다.As shown therein, the nitrogen cooling box body (vat) 10 has a cover 20 that can be opened and closed by the hinge device 30, and inside the nitrogen cooling box body 10 through the central portion of the cover 20. It is made to inject and fill nitrogen, the nitrogen cooling box body 10 and the cover 20 is installed with a pair of locking devices (40, 41) to each other, a plurality of handles 21 on the upper surface of the cover (20) Is installed and configured.

이와 같이 구성된 질소 냉각박스는, 수축 조립할 부품을 질소 냉각박스 몸체(10) 속에 넣고, 커버(20)를 닫은 후, 잠금장치(40,41)를 이용하여 단단히 잠그고, 커버(20)의 중앙 상면에 형성되는 질소주입구에 질소 호스를 연결한 후 질소를 주입하여 해당 부품을 수축 냉각시킨다. 이후 수축냉각된 부품을 꺼내서 해당 부분에 끼워넣어 조립하게 된다.Nitrogen cooling box configured as described above, the components to be shrink-assembled into the nitrogen cooling box body 10, close the cover 20, and then lock tightly by using the locking device (40, 41), the central upper surface of the cover 20 After connecting the nitrogen hose to the nitrogen inlet formed in the nitrogen is injected to shrink the cooling parts. After the shrink-cooled parts are taken out and assembled into the corresponding parts.

그런데, 종래의 질소 냉각박스는, 커버(20)를 닫아 잠근 상태에서 내부에 질소를 충진하고, 수축 냉각이 완료된 후 질소를 배기한 후 커버(20)를 열게 되는데, 도 2와 같이 수직상태로 열어야만 커버(20)가 열린 상태를 유지하므로, 작업자 한명이 커버(20)를 열어 잡고 있는 상태에서 다른 작업자가 부품을 넣어야 한다.However, in the conventional nitrogen cooling box, the nitrogen is filled in the closed state by closing the cover 20, the nitrogen is exhausted after the shrinkage cooling is completed, and the cover 20 is opened, as shown in FIG. Since the cover 20 remains open only when opened, another worker must insert a part while one worker is holding the cover 20 open.

그러므로 적어도 2인 1조의 작업자가 필요하며, 또한 커버(20)의 중량으로 인하여 커버(20)를 열고 닫을때 손이나 손가락이 커버(20)와 몸체(10) 사이에 끼이게 되면 매우 위험한 협착 사고가 발생 될 수 있다.
Therefore, at least two sets of workers are required, and when the cover 20 is opened or closed due to the weight of the cover 20, a hand or a finger is caught between the cover 20 and the body 10, which is a very dangerous stenosis accident. Can be caused.

본 고안은 질소 냉각박스 커버가 무거워 협착에 의한 안전사고 유발에 대한 문제점을 해결하고자 커버에 추를 달아 커버를 열고 닫을때 협착사고를 방지할 수 있도록 한 질소 냉각박스 커버 개폐장치를 제공하기 위한 것이다.The present invention is to provide a nitrogen cooling box cover opening and closing device to prevent the stenosis when opening and closing the cover by attaching a weight to the cover to solve the problem of inducing safety accidents due to the narrow nitrogen cooling box cover. .

본 고안에 의한 질소 냉각박스 커버 개폐장치는,Nitrogen cooling box cover opening and closing device according to the present invention,

질소 냉각박스 몸체에 힌지장치에 의해 커버가 개폐되도록 이루어지고, 몸체와 커버에 쌍을 이루어 설치되는 잠금장치가 구비되는 질소 냉각박스 개폐장치에 있어서, 상기 힌지장치가 설치된 커버의 상면에서 외측으로 돌출되게 고정 설치되는 한쌍의 고정브라켓, 한 쌍의 고정브라켓을 관통하여 고정되는 샤프트, 상기 샤프트의 양단에 고정 결합되는 한 쌍의 추를 포함하여 구성됨을 특징으로 한다.A nitrogen cooling box opening and closing device which is made to open and close a cover by a hinge device on a nitrogen cooling box body, and has a locking device installed in pairs on the body and the cover, wherein the hinge device protrudes outward from an upper surface of the cover on which the hinge device is installed.

이에 도시된 바와 같이,As shown therein,

질소 냉각박스 몸체(10)에 힌지장치(30)에 의해 커버(20)가 개폐되도록 이루어지고, 몸체(10)와 커버(20)에 쌍을 이루어 설치되는 잠금장치(40,41)가 구비되는 질소 냉각박스 개폐장치에 있어서, 상기 힌지장치(30)가 설치된 커버(20)의 상면에서 외측으로 돌출되게 고정 설치되는 한 쌍의 고정브라켓(101), 한 쌍의 고정브라켓(101)을 관통하여 고정되는 샤프트(102), 상기 샤프트(102)의 양단에 고정 결합되는 한 쌍의 추(103)로 이루어진 중량분산장치(100)를 더 포함하여 구성됨을 특징으로 한다.The cover 20 is opened and closed by the hinge device 30 to the nitrogen cooling box body 10, and the locking devices 40 and 41 are provided in pairs to the body 10 and the cover 20. In the nitrogen cooling box opening and closing device, the hinge device 30 penetrates through a pair of fixing brackets 101 and a pair of fixing brackets 101 which are fixed to protrude outward from the upper surface of the cover 20 on which the hinge device 30 is installed. It is characterized in that it further comprises a weight dispersing device 100 consisting of a fixed shaft 102, a pair of weights 103 fixedly coupled to both ends of the shaft 102.

또한 본 고안은 상기 힌지장치(30)에는 커버(20)의 열림방향으로 스프링력이 작용하는 스프링(120)을 더 포함하는 것을 특징으로 한다.In addition, the present invention is characterized in that the hinge device 30 further comprises a spring 120 to which the spring force acts in the opening direction of the cover 20.

이와 같이 구성되는 커버 개폐장치를 구비하는 본 고안의 질소 냉각박스는, 수축 조립할 부품을 질소 냉각박스 몸체(10) 속에 넣고, 커버(20)를 닫은 후, 잠금장치(40,41)를 이용하여 잠그고, 커버(20)의 중앙 상면에 형성되는 질소주입구에 질소 호스를 연결한 후 질소를 주입하여 해당 부품을 수축 냉각시킨다. 이후 수축냉각된 부품을 꺼내서 해당 부분에 끼워넣어 조립하게 된다.Nitrogen cooling box of the present invention having a cover opening and closing device configured as described above, the components to be shrink-assembled into the nitrogen cooling box body 10, and after closing the cover 20, using the locking device (40, 41) Lock and connect the nitrogen hose to the nitrogen inlet formed on the upper surface of the cover 20, and then nitrogen is injected to shrink the cooling parts. After the shrink-cooled parts are taken out and assembled into the corresponding parts.

그런데, 본 고안에 의하면, 커버(20)의 힌지장치(30) 상면부에 고정브라켓(30)이 고정되고, 커버(20)의 외측에서 샤프트(102)가 결합되며, 그 샤프트(102)의 양단부에 추(103)가 설치된 중량분산장치(100)를 더 설치한 것이다.However, according to the present invention, the fixing bracket 30 is fixed to the upper surface of the hinge device 30 of the cover 20, the shaft 102 is coupled to the outside of the cover 20, the shaft 102 of the Weight dispersing device 100 in which the weight 103 is installed at both ends is further installed.

따라서 커버(20)의 무게중심이 추(102)에 힌지장치(30)를 중심으로 분산되므로, 커버(20)가 수직으로 열린 상태와, 커버(20)가 닫힌 상태의 중간단계에서는 추(102)에 의해 커버(20)를 힌지장치(30)의 외측으로 지지하게 된다.Therefore, since the center of gravity of the cover 20 is distributed around the hinge device 30 by the weight 102, the weight 102 is in the intermediate stage of the cover 20 being opened vertically and the cover 20 is closed. ) To support the cover 20 to the outside of the hinge device (30).

그러므로 적은 힘으로도 쉽게 커버(20)를 열고 닫을 수 있으며, 커버(20)가 닫히는 방향으로 작용되는 중량은 매우 작기 때문에 손이나 손가락이 낀다고 하더라도 강제로 커버(20)를 누르지 않는 한 협착사고 우려가 없게 된다.Therefore, the cover 20 can be easily opened and closed with a small force, and the weight acting in the direction in which the cover 20 is closed is very small, so even if a hand or a finger is caught, the stenosis is not forced to press the cover 20. There is no concern.

또한, 본 고안에서는 힌지장치(30)에 커버(30)가 열리는 방향으로 스프링력이 작용되는 스프링(120)을 설치함으로써, 커버(20)가 완전히 닫힌 상태에서 적은 힘으로 열고 닫을 수 있고 협착사고를 방지할 수 있게 된다.
In addition, in the present invention by installing a spring force 120 is applied to the hinge device 30 in the direction in which the cover 30 is opened, the cover 20 can be opened and closed with a small force in a completely closed state and stenosis accident Can be prevented.
