본 발명 장치는 고무확장조인트의 작동 조건인, 그 내부에 고압의 물을 채워 넣은 상태에서, 고무확장조인트를 소정의 방향으로 변위(變位)를 일으켜서 내압(耐壓) 테스트를 행하는 장치에 해당한다.The present invention relates to a device for performing a pressure resistance test in which a rubber expansion joint is displaced in a predetermined direction in a state in which high pressure water is filled in the rubber expansion joint, do.

도 1에서는 고무확장 조인트의 무브먼트(movement) 성능 테스트 장치가 도시되어 있다.In Figure 1 a movement performance testing device of a rubber extension joint is shown.

도 7에서와 같이 고무확장조인트는 중공형의 몸체(100)를 가지고 있으며, 양단에는 구멍이 다수 형성된 플랜지(105)가 형성되고, 이러한 플랜지는 고압의 유체가 지나가는 큰 내경의 파이프에 연결된다. 상기 몸체(100)는 고무를 주성분으로 한 재질로 형성된다.As shown in FIG. 7, the rubber expansion joint has a hollow body 100, and at both ends thereof, a flange 105 having a plurality of holes is formed. The flange is connected to a pipe having a large inner diameter through which a high-pressure fluid passes. The body 100 is made of rubber-based material.

도 8에서 도시된 바와 같이, 고무확장조인트에는 고압의 유체의 유동으로 말미암아서 압축, 인장, 뒤틀림, 벤딩 등의 여러 모드의 외력이 가해지게 되므로, 내구성과 관련된 성능이 고무확장 조인트의 핵심적인 구비조건으로 갖춰져야 한다.As shown in FIG. 8, since various kinds of external forces such as compression, tensile, warping, and bending are applied to the rubber expansion joint due to the flow of the high pressure fluid, the performance related to the durability is essential Condition.

도 1을 참조하면, 도 7에 도시된 고무확장조인트를 도 1의 장치 중앙에 설치를 한 뒤, 고무확장조인트 몸체(100)의 중앙부를 관통하여 테스트보조용부재(200)를 삽입한다.Referring to FIG. 1, after the rubber extension joint shown in FIG. 7 is installed in the center of the apparatus of FIG. 1, the test assistant member 200 is inserted through the center of the rubber extension joint body 100.

테스트보조용부재(200)는 크게 3부분으로 구성된다. 즉 중앙의 유연부재(210)와 그 양단에 연장 형성된 제1,2 강관부재(220,230)을 포함하여 구성된다. 유연부재(210)는 외력에 대하여 굽혀지거나 압축되거나 인장될 수 있는 유연한 소재로 이루어진다.The test assistant member 200 is largely composed of three parts. A flexible member 210 at the center and first and second steel pipe members 220 and 230 extending at both ends thereof. The flexible member 210 is made of a flexible material that can be bent, compressed, or stretched against an external force.

테스트보조용부재(200)의 제1강관부재의 상부 높이는 고무확장조인트 몸체(100) 상부의 플랜지(105) 부분의 높이 보다 상부로 더 돌출되어 있다.The upper height of the first steel pipe member of the test assisting member 200 is further projected above the height of the portion of the flange 105 on the upper portion of the rubber expansion joint body 100.

도 1에서 v1 으로 표시된 부분은 고압의 물이 주입된다. v1 으로 표시된 공간은 두개의 원통형 구조인, 고무확장조인트 몸체(100) 내부와 테스트용보조부재(200)의 외부면이 이루는 공간에 해당하는 공간에 해당한다. 즉 즉 두개의 원통형 구조물 사이에만 고압의 물이 존재한다. 1, high-pressure water is injected into the portion denoted by v1. The space indicated by v1 corresponds to a space corresponding to the space formed by the two cylindrical structures of the inside of the rubber expansion joint body 100 and the outer surface of the test assistant member 200. [ That is, high-pressure water exists only between two cylindrical structures.

v1 으로 표현된 공간의 상하부에는, 상부커버(600) 및 하부커버(610)가 형성되어 v1 공간내의 물이 밀폐된다. v1 내부의 물의 압력은 수압기(20)에 의하여 공급 제어될 수 있다. v1 내부로 물이 공급되는 라인 등은 공지의 기술이므로 상세 설명은 생략한다.In the upper and lower portions of the space represented by v1, the upper cover 600 and the lower cover 610 are formed to seal the water in the v1 space. The pressure of the water inside the v1 can be supplied and controlled by the hydraulic pump 20. and the line through which water is supplied to the inside of the v1 is a well-known technology, so a detailed description thereof will be omitted.

상,하부커버(600,610) 및 고무확장조인트의 플랜지(105)의 체결부에는 볼트 등의 체결수단(71,72,73)이 사용된다. 도 7에서의 볼트구멍(78)에는 이러한 볼트 등의 체결수단이 삽입된다.Fastening means 71, 72, 73 such as bolts are used for fastening portions of the upper and lower covers 600, 610 and the flange 105 of the rubber expansion joint. In the bolt hole 78 in Fig. 7, a fastening means such as a bolt is inserted.

통상적으로, 고무확장조인트의 내압 성능 테스트를 할 경우에 본 발명에서 제시된 테스트보조용부재(200)를 사용함이 없이, 고무확장조인트 내부 전체에 물을 인입하여 테스트를 행하였기 때문에 물의 사용량이 많았던 것은 물론이고, 고압의 물에 의한 응력이, 각종 체결장치 부분에 강하게 작용하여, 볼트 등의 크기가 매우 커지는 등 부속품 가격 상승, 장비 준비의 어려움, 사고발생확률의 증가 등의 문제가 있었다. Generally, in the case of performing the pressure resistance performance test of the rubber expansion joint, since the test was performed by inserting water into the whole of the rubber expansion joint without using the test assistant member 200 proposed in the present invention, Of course, the stress caused by the high-pressure water strongly acts on the various fastening parts, resulting in an increase in the cost of accessories such as bolts and the like, difficulty in equipment preparation, and an increase in the probability of occurrence of accidents.

그런데, 본 발명에서와 같이, v1 공간에만 물이 주입된 상태이므로, 측정 장치에 사용되는 각종 볼트 등의 크기가 경량화 소형화 될 수 있다.However, since water is injected only into the v1 space as in the present invention, the sizes of various bolts used in the measuring apparatus can be reduced in weight and size.

이러한 이유는 도 4를 참조하여 설명한다. 즉, 좌측의 그림과 같이 하나의 면에 압력(P)가 걸린 상태에서 그 단면적을 곱하면, 최종 힘(force) 값을 계산할 수 있는데, 고압의 물에 의하여 동일한 압력이 가해지는 상태에서 본 발명과 같이 두개의 원통형 구조물 사이 공간(v1)에만 물이 존재한다면, 고압의 물에 의한 응력은 단면적이 줄어든 만큼 힘(force)이 줄어드는 결과가 된다는 것을 본 발명에서 적용하였다.This reason will be explained with reference to Fig. That is, as shown in the left figure, the final force can be calculated by multiplying the cross-sectional area by the pressure (P) applied to one surface. In the state where the same pressure is applied by high-pressure water, The present invention has applied to the present invention that when water exists only in the space v1 between two cylindrical structures, the stress due to the high-pressure water is a result of reducing the force as much as the cross-sectional area is reduced.

제1강관부재(220)의 상부에는 보조용부재상판(221)이 형성되며, 이러한 보조용부재 상판(221)에는 제1,2수직고정대받침부재(80, 82)가 부착된다.An auxiliary member upper plate 221 is formed on the upper portion of the first steel pipe member 220 and the first and second vertical fixing members 80 and 82 are attached to the auxiliary member upper plate 221.

이러한 제1,2수직고정대받침부재와 동일한 높이에서 유압 혹은 공압 실린더(30,32)장치가 설치되어, 상기 제1수직고정대받침부재에 측면에 접촉하여 이를 우측(K 방향)으로 미는 역할을 할 수 있다. 이렇게 실린더 장치에 의하여 제1수직고정대받침부재를 우측으로 밀게 되면, 테스트 대상물인 고무확장조인트(100)가 우측으로 밀리게 된다. 실린더는 펌프(10)에 의하여 가동되며, 유압 또는 공압 펌프에 해당된다. 실린더(32) 단부를 제1수직고정대받침부재(80)에 체결할 경우 K 방향에 반대되는 방향으로 당겨 변위를 일으킬 수도 있다.A hydraulic or pneumatic cylinder (30, 32) device is installed at the same height as the first and second vertical fixing table support members, and contacts the side surface of the first vertical fixing table support member and pushes the right side . When the first vertical fixing member support member is pushed to the right side by the cylinder device, the rubber expansion joint 100 as a test object is pushed to the right side. The cylinder is operated by the pump 10 and corresponds to a hydraulic or pneumatic pump. When the end of the cylinder 32 is fastened to the first vertical fixing member 80, it may be pulled in the direction opposite to the K direction to cause displacement.

이러한 상황은 도 8에서 도시된 그림 중 3번째 그림에 해당하는, 고무확장조인트의 작동 조건이 되는 것이다. This situation is an operating condition of the rubber expansion joint corresponding to the third figure in the figure shown in Fig.

즉, 고무확장조인트 제품의 실제 가동 조건 중, 고무확장조인트의 한쪽이 변위되는 상태의 환경하에서도 v1 공간에 있는 고압의 물에 의하여 고무확장조인트의 구조적 강도가 견딜 수 있는지 여부에 대한 성능 테스트가 가능한 것이다.That is, among the actual operating conditions of the rubber expansion joint product, a performance test is conducted to determine whether the structural strength of the rubber expansion joint can withstand the high-pressure water in the space v1 even in an environment in which one side of the rubber expansion joint is displaced It is possible.

제1,2수직고정대받침부재(80,82)의 직상부에 형성된 제1,2수직고정대(50,55)는 제1,2수직고정대받침부재(80,82)를 고정할 수 있다. The first and second vertical fixing members 50 and 55 formed on the first and second vertical fixing members 80 and 82 may fix the first and second vertical fixing members 80 and 82.

한편, 제1,2수직고정대 위치에 실린더 수단을 구비할 경우, 도 8에서 도시된 고무확장조인트가 압축(compression) 혹은 인장(elongation) 되는 모드를 연출하여 테스트가 가능하며, 도 1의 경우는 고무확장조인트 단부가 변위(變位)가 되는 래터럴무브먼트(lateral movement) 의 모드( 도 8의 세번째 그림) 에 해당하는 것이다.In the case where the cylinder means is provided at the first and second vertical fixing positions, the rubber extension joint shown in FIG. 8 can be tested by performing a compression or elongation mode. In the case of FIG. 1, Corresponds to the mode of the lateral movement (third figure in Fig. 8) in which the end of the rubber expansion joint is displaced.

도 3에서는 도 8의 네번째 그림에 해당하는 앵귤러 무브먼트 모드의 외력이 작용하는 상황을 만들어서, 고무확장조인트의 내압 성능 테스트를 행하는 것이다.In FIG. 3, a situation in which an external force in the angular movement mode corresponding to the fourth figure in FIG. 8 is made, and the internal pressure performance test of the rubber expansion joint is performed.

앵귤러 무브먼트(angular movement)는 소위 고무확장조인트를 그 길이 방향에 수직하게 꺽이도록 (벤딩시키는) 외력을 가할 때를 말한다.The angular movement refers to the application of an external force to bend a so-called rubber expansion joint perpendicularly to its longitudinal direction.

웨지(wedge) 부재를 제1,2수직고정받침부재(80,82) 의 상부면과 제1,2수직고정대(50,55)의 하부면 사이에 삽입, 형성하여 일정한 회전을 하게 할 수 있다.A wedge member may be inserted between the upper surface of the first and second vertical fixed supporting members 80 and 82 and the lower surfaces of the first and second vertical fixing tables 50 and 55 to rotate uniformly .

웨지는 그 형상적 특징상 경사지게 형성되어 있으므로, 도 3과 같이 우측이 기울어지도록 고무확장조인트를 변위(變位)시킬 수 있게 된다.Since the wedge is formed so as to be inclined in shape, the rubber extension joint can be displaced so that the right side is inclined as shown in FIG.

도 3에서 도시된 바와 같이, 웨지부재의 삽입에 의하여 고무확장조인트의 몸체(100) 부분의 우측(도 3 기준) 부분이 아래쪽으로 눌러지게 된다. 이 상황은 도 8의 네번째 그림에 해당하는, 앵귤러 무브먼트 변위를 받고 있는 것에 해당하며, 이 상태에서 고무확장조인트의 내압 성능 시험이 이루어지게 된다. 3, the right side (refer to FIG. 3) portion of the body 100 portion of the rubber expansion joint is pushed downward by the insertion of the wedge member. This situation corresponds to the displacement of the angular movement corresponding to the fourth figure of FIG. 8. In this state, the pressure resistance test of the rubber expansion joint is performed.

본 발명의 상기 실시예와는 달리 도 5 및 도 6에서는 고무확장조인트 내부에 테스트보조용부재가 생략된 구성을 가지는 테스트 장치의 실시예를 도시하고 있다.5 and 6 illustrate an embodiment of a test apparatus having a structure in which a test assistant member is omitted from inside a rubber expansion joint, unlike the above embodiment of the present invention.

고무확장조인트(1100)의 플랜지(1101) 상측에 상부커버(60)를 덮어 고무확장조인트 내부를 밀폐시키고 상부커의 직상부에 바로 제1,2수직고정대받침부재(80,82)를 연결한 뒤, 앞선 실시예와 같은 방법으로 고무확장조인트가 K 방향 혹은 R 방향(도 6 참조)를 변위를 일으키도록 한 상태로, 내압(耐壓) 성능 테스트를 수행하게 된다는 점이 앞선 실시예와 차이점이다. 도 5의 실시예의 측정 장치에 사용되는 고무확장조인트의 내경은 앞선 실시예의 경우보다 작은 것을 사용함이 바람직하다. 내압 테스트용 물은 v2 공간 즉, 고무확장조인트(1100)의 내부(v2)에 모두 채워지게 되며, 앞선 실시예와 같이 v1 공간(고무확장조인트와 테스트보조용부재 사이 공간) 공간과는 다르다.The upper cover 60 is covered on the upper side of the flange 1101 of the rubber extension joint 1100 to seal the inside of the rubber expansion joint and the first and second vertical support members 80 and 82 are directly connected to the upper portion of the upper Thereafter, in the same manner as in the previous embodiment, the rubber expansion joint is subjected to a pressure resistance performance test in such a manner as to cause displacement in the K direction or the R direction (see FIG. 6) . It is preferable that the inner diameter of the rubber expansion joint used in the measuring apparatus of the embodiment of Fig. 5 is smaller than that of the previous embodiment. The pressure test water is filled in the v2 space, that is, the inside v2 of the rubber expansion joint 1100, and is different from the v1 space (space between the rubber expansion joint and the test auxiliary member) space as in the previous embodiment.

즉, 고무확장조인트 크기가 작을 경우에는 그 내부에 수압이 작은 경우에 해당하는 것이므로, 도 3에서와 같은 대용량의 고무확장조인트 테스트를 위한 테스트보조용부재(200)가 굳이 필요없게 된다. 고무확장조인트 내부 공간 v1 의 부피가 그다지 크지 않고 체결부재(75) 등에 걸리는 힘도 크지 않기 때문이다.That is, when the size of the rubber expansion joint is small, it corresponds to a case in which the water pressure is small. Therefore, the test assistant member 200 for testing a rubber expansion joint of a large capacity as shown in FIG. 3 is not necessary. The volume of the rubber expansion joint internal space v1 is not so large and the force applied to the fastening member 75 and the like is not large.

요약하면, 도 3의 경우는 높은 압력이 가해지는 큰 중공을 가진 고무확장조인트에 대하여 사용하고 도 5의 경우는 작은 고무확장조인트(1100)의 내압 테스트용 장치에 해당한다. In summary, the case of FIG. 3 is used for a rubber expansion joint having a large hollow to which a high pressure is applied, and the case of FIG. 5 corresponds to an apparatus for internal pressure test of a small rubber expansion joint 1100.

상기 실시예들에 있어서, 제1,2 수직고정대는 유압 또는 공압 실린더로 형성될 수 있으며, 이 경우, 상기 제1,2수직고정대받침부재의 상부와 체결되어서, 제1,2수직고정받침부재를 상방 혹은 하방으로 변위시켜서, 도 8의 1번째 및 2번째 모드로 고무확장조인트의 단부를 변위시키는 형태로 만들어서 내압 테스트를 행할 수도 있다.In the above embodiments, the first and second vertical fixtures may be formed of hydraulic or pneumatic cylinders. In this case, the first and second vertical fixture members are coupled to the first and second vertical fixture support members, And the end portion of the rubber expansion joint is displaced in the first and second modes in Fig. 8, thereby performing the withstand pressure test.
