본 고안은 사상압연기(Finishing Mill)의 자동게이지제어장치에서 오일펌프의 압력을 측정하는 압력계에 오일펌프 압력을 전달하기 위해 사용되는 도압관 설치구조에 관한 것이다.The present invention relates to a pressure pipe installation structure used to transfer the oil pump pressure to the pressure gauge for measuring the pressure of the oil pump in the automatic gauge control device of the finishing mill (Finishing Mill).

사상압연공정은 조압연에서 작업된 슬래브를 고객이 요구하는 최종 사이즈로 제조하는 공정으로서 용도에 맞는 온도확보에 의한 재질확보, 양호한 표면 및 형상을 확보하는 등 열연공정의 핵심공정이며, 생산성 향상을 위해 6~7개의 롤이 연속적으로 배치된 텐덤(tandem) 형식의 압연기를 갖추고 있다.The finishing rolling process is the manufacturing process of slab processed in rough rolling to the final size required by the customer.It is the core process of the hot rolling process, which secures the material by securing the temperature for the purpose and secures the good surface and shape. The tandem rolling mill is equipped with six to seven rolls arranged in series.

상기 압연기는 소재의 압연을 수행하는 상하 한 쌍의 압연롤과, 그 압연롤 사이의 간격을 조절하는 압하장치와, 두께의 정확성을 확보하기 위하여 압연기 출측을 통과하는 소재의 두께편차량을 수집하고 압연롤 사이의 간격을 제어하기 위한 신호를 상기 압하장치에 출력하는 자동게이지제어장치(AGC ; Automatic Gauge Control)와, 상기 압연롤의 굽힘변형량을 제어하는 벤더와, 상기 벤더를 제어하여 굽힘변형량을 보상하는 벤더제어장치와, 소재에 가해지는 압연하중을 검출하는 하 중검출장치를 포함한다.The rolling mill is a pair of upper and lower rolling rolls for performing the rolling of the material, a rolling device for adjusting the interval between the rolling rolls, and to collect the thickness deviation of the material passing through the rolling mill exit to ensure the accuracy of the thickness; An automatic gauge control (AGC) for outputting a signal for controlling the interval between the rolling rolls to the pressing device, a bender for controlling the bending strain of the rolling roll, and a bending strain by controlling the bender. And a bender control device for compensating and a load detection device for detecting a rolling load applied to the material.

한편, 상기 자동게이지제어장치는 오일펌프의 압력을 측정하기 위한 압력계를 구비한다.On the other hand, the automatic gauge control device is provided with a pressure gauge for measuring the pressure of the oil pump.

도 1에 도시된 바와 같이, 상기 오일펌프 압력계(5)는 오일펌프(10)의 출력측 즉, 출력관(30) 연결 부분과 도압관(40)으로 연결되어 있어 오일펌프 압력을 전달받아 측정할 수 있도록 되어 있다.As shown in FIG. 1, the oil pump pressure gauge 5 is connected to the output side of the oil pump 10, that is, the output pipe 30 is connected to the pressure pipe 40 so that the oil pump pressure may be received and measured. It is supposed to be.

그런데, 상기 도압관(40)이 단순한 파이프(pipe)로 이루어져 있어 오일펌프(10)의 작동시 발생하는 진동 및 충격 또는 그 외 외부로부터 가해지는 임의의 충격에 의해 쉽게 파손될 수 있다.By the way, the pressure pipe 40 is made of a simple pipe (pipe) can be easily damaged by vibration and shock generated during operation of the oil pump 10 or any shock applied from the outside.

이 경우, 상기 도압관(40)에는 오일펌프(10) 출측의 고압(315kg/cm2)이 걸려 있으므로 오일의 비산력이 매우 강력하여 안전사고 발생의 우려가 매우 크다.In this case, since the high pressure (315kg / cm 2 ) of the oil pump 10 is caught on the pressure pipe 40, the scattering force of the oil is very strong, and there is a great risk of a safety accident.

더욱이 압연중에는 상기 오일펌프(10)의 작동중지가 불가능하도록 시스템이 구성되어 있어서 더욱 위중한 설비사고를 초래하게 되는 문제점이 있었다.In addition, during the rolling, the system is configured such that the operation of the oil pump 10 cannot be stopped, resulting in more serious equipment accidents.

이에 본 고안은 상기와 같은 목적을 달성하기 위해 안출된 것으로, 도압관이 오일펌프 작동에 따른 진동과 충격 및 그 외 외력에 의해서 쉽게 파손되지 않게 됨으로써 오일 비산으로 인한 안전사고 및 설비사고를 예방할 수 있도록 된 자동게이지제어장치의 오일펌프 압력계 도압관 설치구조를 제공함에 그 목적이 있다.The present invention has been devised to achieve the above object, the pressure vessel is not easily damaged by vibration and shock and other external forces due to the operation of the oil pump can prevent safety accidents and equipment accidents due to oil splashing. The purpose is to provide an oil pump pressure gauge pressure gauge installation structure of the automatic gauge control device.

상기와 같은 목적을 달성하기 위한 본 고안은,The present invention for achieving the above object,

오일펌프 압력계가 오일펌프의 출력관 연결부와 도압관으로 연결된 자동게이지제어장치의 오일펌프 압력계 도압관 설치구조에 있어서,In the oil pump pressure gauge pressure gauge installation structure of the automatic gauge control device in which the oil pump pressure gauge is connected to the output pipe connection of the oil pump by a pressure gauge,

상기 도압관이 고압호스로 이루어진 것을 특징으로 한다.The pressure pipe is characterized by consisting of a high pressure hose.

또한, 상기 도압관은 커플러를 매개로 오일펌프의 출력관 연결부에 연결된 것을 특징으로 한다.In addition, the pressure pipe is characterized in that connected to the output pipe connection of the oil pump via a coupler.

상기와 같은 본 고안의 구성에 따르면, 도압관이 고압호스로 이루어짐으로써 오일펌프 작동에 따른 진동이나 충격 또는 그 외 외력이 작용하여도 유연하게 구부러지면서 작용력에 대응하게 되므로 파손이 발생하지 않게 된다. According to the configuration of the present invention as described above, since the pressure pipe is made of a high-pressure hose, even if the vibration or shock caused by the operation of the oil pump or other external force acts flexibly to respond to the action force does not cause damage.

따라서, 강력한 오일 비산으로 인한 안전사고가 발생하지 않게 되며, 결국 설비사고도 미연에 방지할 수 있게 되는 효과가 있다.Therefore, safety accidents are not generated due to strong oil splashing, and thus, there is an effect of preventing equipment accidents in advance.

이하, 본 고안을 첨부된 도면을 참조하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 2는 본 고안에 따른 자동게이지제어장치의 오일펌프 압력계 도압관 설치구조를 도시한 도면이다. 종래 구성과 동일한 부분에는 동일한 참조번호를 부여하기로 한다.2 is a view showing the oil pump pressure gauge pressure gauge installation structure of the automatic gauge control device according to the present invention. The same reference numerals will be given to the same parts as the conventional configuration.

도시된 바와 같이, 오일펌프(10)에는 오일이 공급되는 입력관(20)과 압축된 오일이 압송되는 출력관(30)이 연결되어 있다.As shown, the oil pump 10 is connected to the input tube 20 is supplied with the oil and the output tube 30, the compressed oil is pumped.

자동게이지제어장치의 압력계(5)로 상기 오일펌프(10) 출력압력을 전달하기위하여 도압관(50)이 상기 출력관(30)의 연결부에 연결된다.A pressure pipe 50 is connected to the connection portion of the output pipe 30 to transfer the output pressure of the oil pump 10 to the pressure gauge 5 of the automatic gauge control device.

본 고안은 상기 도압관(50)이 호스(hose)로 이루어진 것에 특징이 있다. 이때 오일펌프(10) 출력측의 고압에 대항할 수 있도록 상기 도압관(50)은 내압성능이 우수한 고압호스로 이루어진다.The present invention is characterized in that the pressure pipe 50 is made of a hose (hose). At this time, the pressure pipe 50 is made of a high pressure hose with excellent pressure resistance performance so as to counter the high pressure of the oil pump 10 output side.

한편, 상기 도압관(50)은 상기 출력관(30)의 연결부에 커플러(coupler;60)를 매개로 연결된다.On the other hand, the pressure pipe 50 is connected to the connection portion of the output tube 30 via a coupler (coupler) (60).

커플러(60)로서는 일단에 호스가 연결되고 타단에는 니플(상기 출력관(30)의 오일펌프 연결부에 형성됨)이 연결되는 타입의 것을 사용하고, 고압에 대응하기 위하여 유압잭커플러(hydraulic jack coupler)를 사용하는 것이 바람직하다.As the coupler 60, a hose is connected at one end and a nipple (formed at the oil pump connection part of the output pipe 30) is connected at the other end, and a hydraulic jack coupler is used to cope with high pressure. It is desirable to.

상기 유압잭커플러는 특수 강재를 사용한 양로 개폐형 커플러로서, 진동과 충격에 강하고 특히 압력손실이 적도록 설계되어 있어 유압기기의 연결에 최적인 연결구이다.The hydraulic jack coupler is an open and close coupler using a special steel material, which is designed to be strong against vibration and shock, and in particular, to reduce pressure loss.

상기와 같이 본 고안은 압력계(5)의 도압관(50)이 고압호스로 이루어짐으로 써 오일펌프(10)의 작동시 진동이나 충격이 전달되어도 그에 따라 유연하게 변형되면서 대응하게 된다.As described above, the present invention is made by the pressure pipe 50 of the pressure gauge 5 made of a high-pressure hose, so that even if vibration or shock is transmitted during operation of the oil pump 10, it is flexibly deformed accordingly.

또한, 주변의 작업자나 작업물 등이 이동할 때 간섭되어도 가해지는 외력에 따라 유연하게 변형될 뿐 관로 자체나 연결부위에 큰 충격을 받지 않게 된다.In addition, even if the worker or the work around, such as when moving, the flexible deformation according to the external force is applied is not subjected to a large impact on the pipeline itself or the connection portion.

따라서, 도압관(50)이 잘 파손되지 않으며, 이에 따라 파손부위를 통한 오일의 비산이 발생하지 않게 되므로, 고압의 오일 비산으로 인한 안전사고가 방지된다.Therefore, the pressure pipe 50 is not easily broken, and thus no scattering of oil through the broken portion occurs, thereby preventing a safety accident due to scattering of high pressure oil.

또한, 압연중 오일펌프의 작동유 누출이 발생하지 않게 되므로 사상압연 공정이 정상적으로 진행되어 제품의 품질을 보장할 수 있게 되고, 시스템 가동을 중지할 필요가 없게 되므로 생산성 향상에 일조하게 된다.In addition, since the oil leakage of the oil pump during rolling does not occur, the finishing rolling process is normally performed to ensure the quality of the product, and it is not necessary to stop the system operation, thereby improving productivity.
