본 발명은 고속철도차량의 승강문에 설치, 공기가 공급되면 팽창되어 문틈을 제거하는 팽창실(膨脹seal)의 불량 등으로 인하여 팽창실에서 압력이 누설되는지를 1인의 점검원이 정확하게 검사할 수 있도록 한 고속철도차량용 승강문의 팽창실 압력 누설 시험기에 관한 것이다.The present invention is installed on the lifting door of the high-speed railway vehicle, so that when the air is supplied, it can be expanded and the inspection person can accurately check whether the pressure leaks from the expansion chamber due to the failure of the expansion chamber to remove the door gap. An expansion chamber pressure leak tester for a lifting door for a high speed railway vehicle.

일반 철도차량과 달리 200km/h 이상으로 주행하는 고속철도차량은 차내의 기밀이 일정 수준 이상으로 유지되어 있지 못하면 주행 시 소음에 의한 귀울음(이명) 증상이 발생되어 승객에게 안락을 제공할 수 없게 된다.Unlike general railroad cars, high-speed rail cars that travel more than 200km / h will not be able to provide comfort to passengers if the car's airtightness is not maintained above a certain level.

따라서 고속철도차량은 차내가 외부와 차단된 구조를 이루고 있으며, 차내와 외부를 잇는 유일한 수단인 승강구는 도 1과 같이 승강문(1)의 둘레를 따라 밀봉부재를 설치함으로써 문틈(G)이 제거된 구조를 이루고 있다. 이때 밀봉부재는 승강문(1)이 닫힌 상태에서 고속철도차량이 일정 속도 이상으로 주행하면 승강문(1)의 내부에 형성된 공기 주입로(1b)를 통한 공기의 공급으로 팽창, 승강구의 둘레면에 밀 착되도록 구성된 팽창실(膨脹seal)(2)이다.Therefore, the high-speed railway vehicle has a structure in which the inside of the vehicle is blocked from the outside, and the hatch, which is the only means connecting the inside and the outside of the vehicle, is provided with a sealing member along the circumference of the lifting door 1 to remove the door gap G. It is structured. At this time, the sealing member is expanded and supplied to the circumferential surface of the hatch by supplying air through the air injection passage 1b formed inside the lift door 1 when the high speed railway vehicle runs at a predetermined speed or more while the lifting door 1 is closed. Expansion chamber (2) configured to be in close contact.

한편 공기를 팽창실(2)로 공급하는 장치에 관하여 살펴보면, 도 2와 같이 공기 공급원(10)과, ㄱ자형으로 형성되어 한쪽에 에어노즐(21)이 형성되고 다른 쪽에 니플(22)이 형성되며 내부에 에어노즐(21)과 니플(22)의 구멍을 연결하는 유로(23)가 형성된 공기 주입기구(20)와, 공기 공급원(10)으로부터 제공된 공기가 공기 주입기구(20)로 수송되도록 공기 공급원(10)과 공기 주입기구(20)의 니플(22)을 연결하는 에어라인(30)과, 이 에어라인(30)의 중간에 설치된 전자밸브(40) 등으로 이루어진다.On the other hand, a device for supplying air to the expansion chamber (2), as shown in Figure 2, the air supply source 10, and is formed in the letter 'A' form the air nozzle 21 on one side and the nipple 22 is formed on the other side And an air injection mechanism 20 in which a flow path 23 connecting the holes of the air nozzle 21 and the nipple 22 is formed, and the air supplied from the air supply source 10 is transported to the air injection mechanism 20. It consists of an air line 30 which connects the air supply source 10 and the nipple 22 of the air injection mechanism 20, and the solenoid valve 40 provided in the middle of this air line 30.

여기에서 공기 주입기구(20)는 승강문(1)이 닫힌 때 그 에어노즐(21)이 승강문(1)의 안쪽면에 형성된 공기 주입구멍(1a)으로 자연히 삽입되는 위치에 설치되는 한편 공기 주입구멍(1a)은 공기 주입로(1b)와 연결되도록 형성되어 있고, 전자밸브(40)는 고속철도차량이 일정 속도 이상으로 주행 시 열림 작동되도록 구성되며, 전자밸브(40)에서 도면부호 41은 수동 조작버튼으로 이 수동 조작버튼(41)을 누름 조작하면 전자밸브(40)가 열림 작동된다.Here, the air injection mechanism 20 is installed at a position where the air nozzle 21 is naturally inserted into the air injection hole 1a formed in the inner surface of the lifting door 1 when the lifting door 1 is closed. The injection hole 1a is formed to be connected to the air injection path 1b, and the solenoid valve 40 is configured to open when the high speed rail vehicle runs at a predetermined speed or higher, and reference numeral 41 in the solenoid valve 40 When the manual operation button 41 is pressed and operated by the manual operation button, the solenoid valve 40 is opened.

그러나 상기와 같은 고속철도차량은 점검 시 팽창실(2)에서 압력(공급된 공기)이 누설되고 있는지의 여부를 검사하는 데 있어서 다음과 같은 애로사항이 있었다.However, the high-speed railway vehicle as described above has the following difficulties in checking whether the pressure (air supplied) is leaking in the expansion chamber (2) during the inspection.

첫째, 팽창실(2)의 압력 누설을 검사하기 위해서는 공기를 팽창실(2)로 공급 하여 팽창실(2)을 팽창시켜야 하고, 공기를 팽창실(2)로 공급하기 위해서는 승강문(1)을 닫아 에어노즐(21)을 공기 주입구멍(1a)으로 삽입시켜야 하는 바, 주지와 같이 근래 철도차량은 승강문(1)이 전자식으로 작동되도록 구성되므로 전원의 공급이 차단된 상태, 즉 시동 오프 상태에서는 팽창실(2)의 압력 누설을 검사할 수조차 없었다.First, in order to check the pressure leakage of the expansion chamber (2), it is necessary to expand the expansion chamber (2) by supplying air to the expansion chamber (2), and the lifting door (1) to supply air to the expansion chamber (2) The air nozzle 21 must be inserted into the air injection hole 1a by closing the bar. As is well known, the railroad car is configured to operate the lifting door 1 electronically. In the state, the pressure leakage of the expansion chamber 2 could not even be checked.

현재 팽창실(2)의 압력 누설 검사는 어떠한 전용의 장비도 없어 점검원이 자신의 감각을 동원하여 검사하는 형편이었다.At present, the pressure leak test of the expansion chamber 2 was not carried out by any equipment, and the inspector mobilized his senses.

때문에 둘째, 도 1과 같이 팽창실(1)은 승강문(1)이 닫히면 볼 수 없게 되어 육안이나 촉감을 이용해서는 검사할 수 없었고, 대부분 청각을 이용하여 압력이 누설되는 소리를 감지하는 방법으로 검사하였는데, 방법 자체가 너무나 원시적이어서 신속하고 정확한 검사가 불가능하였다.Therefore, as shown in FIG. 1, the expansion chamber 1 cannot be seen when the lifting door 1 is closed and cannot be inspected using the naked eye or the touch, and most of them use a hearing to detect a sound leaking pressure. The method itself was so primitive that rapid and accurate testing was not possible.

한편 빛을 문틈(G)으로 조사하여 빛이 반대편으로 투과되는지를 육안으로 확인하는 방식의 검사도 있었다. 그렇지만 이 검사도 원시적인 방법이었고, 검사에 2인 이상의 인력이 요구된다는 문제점이 있었다.On the other hand, there was also a method of visually checking whether light is transmitted to the opposite side by irradiating light through the door gap G. However, this test was also a primitive method, and there was a problem that two or more people were required for the test.

셋째, 현 실정이 이러하다 보니 팽창실(2)의 불량(압력 누설)이 점검원에 의하여 발견되는 것보다는 주행 시 귀울음 증상을 느낀 승객의 신고로 발견되는 경우가 대부분인지라 고속철도차량의 신뢰성 저하로 이어지는 문제점도 있었다.Third, since the current situation is such that the failure (pressure leakage) of the expansion chamber (2) is found by the report of the passengers who have felt the symptoms of driving, rather than being detected by the inspector, leading to a decrease in the reliability of the high-speed railway vehicle There was a problem.

본 발명은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 승강문을 완전히 닫지 않은 상태에서도 공기가 팽창실로 공급되도록 하는 연결라인, 이 라인을 따라 흐르는 공기의 압력을 측정하는 계측기를 구비함으로써 팽창실에서 압력이 누설되는지를 과학적인 방식에 의하여 간단하고 신속하며 정확하게 검사할 수 있는 고속철도차량용 승강문의 팽창실 압력 누설 시험기를 제공하는 데 목적이 있다. The present invention has been made to solve the problems of the prior art, expansion chamber by having a connection line for supplying air to the expansion chamber even when the lifting door is not completely closed, the measuring instrument for measuring the pressure of air flowing along the line The purpose of the present invention is to provide a pressure leak tester for the expansion door of a high-speed railway vehicle landing door, which can easily, quickly and accurately check whether the pressure leaks through the scientific method.

상기와 같은 기술적 과제를 달성하기 위한 본 발명은 고속철도차량용 승강문의 팽창실(膨脹seal)에서 압력이 누설되는지 검사할 때 공기 주입기구의 에어노즐을 대신하여 상기 승강문의 공기 주입구멍에 삽입되는 시험용 에어노즐 및 상기 공기 주입기구의 니플을 대신하여 상기 니플이 연결되는 에어라인에 삽입되는 시험용 니플과, 상기 시험용 에어노즐과 시험용 니플을 연결하는 에어호스와, 상기 에어호스에 설치된 압력계를 포함하는 것을 특징으로 하여 가능하게 된다.The present invention for achieving the above technical problem is a test air inserted into the air injection hole of the lifting door in place of the air nozzle of the air injection mechanism when the pressure leak in the expansion chamber (膨脹 seal) of the lifting door for high-speed railway vehicle And a test nipple inserted into an air line to which the nipple is connected instead of a nozzle and a nipple of the air inlet mechanism, an air hose connecting the test air nozzle and the test nipple, and a pressure gauge installed on the air hose. It becomes possible by this.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다. 참고로 설명의 편의를 위하여 종래기술과 중복되는 부분은 그와 관련한 구체적인 설명을 생략하고 종래기술과 동일한 도면부호를 사용하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. For reference, a portion overlapping with the prior art will be omitted for convenience of description and the same reference numerals as in the prior art will be omitted.

본 발명에 따른 고속철도차량용 승강문의 팽창실 압력 누설 시험기가 도 3과 도 4에 도시되어 있다.The expansion chamber pressure leakage tester of the lifting door for a high speed railway vehicle according to the present invention is shown in Figs.

도 3 및 도 4에 도시된 바와 같이 본 발명에 따른 고속철도차량용 승강문의 팽창실 압력 누설 시험기는 시험용 에어노즐(50), 시험용 니플(60), 에어호스(70), 압력계(80), 개폐밸브(90), 호스 클램프(100) 등으로 이루어진다.3 and 4, the expansion chamber pressure leakage tester for the high-speed railway vehicle lifting door according to the present invention is a test air nozzle 50, a test nipple 60, an air hose 70, a pressure gauge 80, an open / close valve 90, the hose clamp 100, and the like.

시험용 에어노즐(50) 및 시험용 니플(60)은 각각 승강문(1)의 공기 주입구멍(1a)과 공기 주입기구(20)의 니플(22)이 연결되는 에어라인(30)에 삽입되는 것으로서, 이를 위하여 각각 공기 주입기구(20)의 에어노즐(21) 및 니플(22)과 그 형상이 일치하도록 형성된다.(공기 주입기구 관련 도면 : 도 1)The test air nozzle 50 and the test nipple 60 are respectively inserted into the air line 30 to which the air injection hole 1a of the lifting door 1 and the nipple 22 of the air injection mechanism 20 are connected. To this end, the air nozzles 21 and the nipples 22 of the air injection mechanism 20 are formed to match the shapes thereof.

이와 같은 시험용 에어노즐(50) 및 시험용 니플(60)은 평상시 공기 주입구멍(1a)과 에어라인(30)에 삽입되어 연결되는 것이 아니라 팽창실(2)에서 압력이 누설되는지를 검사하고자 할 때에 한하여 각각 에어노즐(21) 및 니플(22)을 대신 삽입되는 것이다.When the test air nozzle 50 and the test nipple 60 are not normally connected to the air injection hole 1a and the air line 30 but are connected to the air injection hole 1a to check whether the pressure leaks from the expansion chamber 2, Only the air nozzle 21 and the nipple 22 are inserted instead.

에어호스(70)는 시험용 에어노즐(50)과 시험용 니플(60)이 각각 공기 주입구멍(1a)과 에어라인(30)에 삽입된 때 공기 공급원(10)으로부터 제공된 공기가 에어라인(30)과 시험용 니플(60)을 순차적으로 경유하여 시험용 에어노즐(50)로 수송되도록 시험용 에어노즐(50)과 시험용 니플(60)을 연결하는 것이다.The air hose 70 has air provided from the air supply source 10 when the test air nozzle 50 and the test nipple 60 are inserted into the air injection hole 1a and the air line 30, respectively. The test air nozzle 50 and the test nipple 60 are connected so as to be transported to the test air nozzle 50 via the test nipple 60 sequentially.

여기에서 에어호스(70)는 굴곡성이 있어 자유로이 굴곡할 수 있기 때문에 협소한 공간에서도 사용이 편리한 한편 내부를 따라 흐르는 공기의 압력(참고로 팽창 실로 공급되는 공기의 압력은 약 1.5bar이다) 이상을 견딜 수 있는 정도의 강도를 갖는 것이라면 어떠한 타입의 호수라도 적용이 가능하다.Since the air hose 70 is flexible and can be bent freely, it is easy to use even in a narrow space, while the air hose 70 (for reference, the pressure of the air supplied to the expansion chamber is about 1.5 bar) can be used. Any type of lake can be used as long as the strength is tolerable.

압력계(80)는 에어호스(70)의 중간에 설치되어 에어호스(70)의 내부를 따라 흐르는 공기의 압력을 측정, 이 측정값을 시각적으로 표시하여 점검원이 일견에 알 수 있게 하는 역할을 한다.The pressure gauge 80 is installed in the middle of the air hose 70 to measure the pressure of air flowing along the inside of the air hose 70, and visually display the measured value so that the inspector can know at a glance. do.

여기에서 공기가 팽창실(2)로 공급되어 팽창실(2)이 완전히 팽창된 때 압력계(80)의 측정값은 팽창실(2)과 에어호스(70)가 서로 통하여 있기 때문에 곧 팽창실(2)의 압력 수치이다.Here, when air is supplied to the expansion chamber 2 and the expansion chamber 2 is fully inflated, the measurement value of the pressure gauge 80 is short because the expansion chamber 2 and the air hose 70 pass through each other. 2) is the pressure value.

개폐밸브(90)는 시험용 에어노즐(50)과 압력계(80) 또는 시험용 니플(60)과 압력계(80) 사이에 위치되도록 에어호스(70)에 설치되는 것으로서, 에어호스(70)의 내부를 따라 흐르는 공기의 양을 조절하거나 멈추게 한다.The on-off valve 90 is installed in the air hose 70 so as to be located between the test air nozzle 50 and the pressure gauge 80 or the test nipple 60 and the pressure gauge 80, and the inside of the air hose 70 Adjust or stop the amount of air flowing along it.

이러한 개폐밸브(90)는 자체의 통로에 뚫려 있는 원통형의 구멍에 끼워 있는 플러그를 돌려서 유량을 가감하도록 구성된 에어콕이다.The on-off valve 90 is an air cock configured to increase or decrease the flow rate by turning a plug fitted into a cylindrical hole drilled in its passage.

호스 클램프(100)는 에어호스(70)를 따라 흐르는 공기가 연결 틈새로 누설되는 것을 방지하는 역할을 하는 것으로 이와 동일한 작용을 기대할 수 있는 것이라면 어떤 것이라도 대용이 가능하다.The hose clamp 100 serves to prevent the air flowing along the air hose 70 from leaking into the connection gap, and any one may be substituted as long as it can expect the same action.

상기와 같이 구성되는 본 발명에 의한 팽창실(2)의 압력 누설 검사는 다음과 같은 과정으로 이루어진다.Pressure leakage inspection of the expansion chamber 2 according to the present invention configured as described above is made of the following process.

먼저 개폐밸브(90)가 열린 상태이면 닫힘 작동되도록 조작하여 공기가 에어호스(70)를 따라 일부 구간 이상 흐를 수 없는 상태를 유지한다. 그리고 승강문(1)이 닫힌 상태이면 승강문(1)을 열어서 공기 주입기구(20)의 에어노즐(21)을 승강문(1)의 공기 주입구멍(1a)으로부터 분리하고, 서로 연결된 공기 주입기구(20)의 니플(22)과 에어라인(30)의 연결을 해제하여 분리한다. 그러면 팽창실(2)의 압력 누설 검사를 위한 사전 준비가 완료된다.First, when the on-off valve 90 is opened, the valve is operated to be closed to maintain a state in which air cannot flow more than a section along the air hose 70. When the lifting door 1 is closed, the lifting door 1 is opened to separate the air nozzle 21 of the air injection mechanism 20 from the air injection hole 1a of the lifting door 1, and the air injection connected to each other. Disconnect and disconnect the nipple 22 of the instrument 20 and the airline 30. Preliminary preparation for the pressure leakage inspection of the expansion chamber 2 is then completed.

다음 시험용 에어노즐(50)을 공기 주입구멍(1a)에 삽입함과 아울러 시험용 니플(60)을 에어라인(30)에 각각 삽입하여 연결하고, 도 4에서 도면부호 150으로 나타낸 Ｃ형 클램프를 이용, 도 4에서처럼 수동 조작버튼(41)을 누름 조작하여 전자밸브(40)를 열린 상태로 유지한다. 그러면 팽창실(2)의 압력 누설 검사를 위한 본 발명의 세팅이 완료된다.Next, the test air nozzle 50 is inserted into the air injection hole 1a, and the test nipples 60 are inserted and connected to the air line 30, respectively, using a C-type clamp shown by reference numeral 150 in FIG. , By pressing the manual operation button 41 as shown in Figure 4 to maintain the solenoid valve 40 in the open state. This completes the setting of the present invention for pressure leak inspection of the expansion chamber 2.

그 다음 이와 같은 상태에서 개폐밸브(90)를 열림 작동되도록 조작한다. 그러면 전자밸브(40)가 열림 조작된 때 공기 공급원(10)으로부터 전자밸브(40), 에어라인(30), 시험용 니플(60)을 순차적으로 경유하여 이미 에어호스(70)로 수송된 공기는 시험용 에어노즐(50), 공기 주입구멍(1a), 공기 주입로(1b)를 순차적으로 경 유하여 팽창실(2)로 수송된다. 이때 팽창실(2)은 물론 팽창되고, 압력계(80)는 에어호스(70)의 내부를 따라 흐르는 공기의 압력을 측정하여 표시한다.Then in such a state to operate the opening and closing valve 90 is opened. Then, when the solenoid valve 40 is opened and operated, the air already transferred to the air hose 70 from the air source 10 via the solenoid valve 40, the air line 30, and the test nipple 60 is sequentially It is transported to the expansion chamber 2 via the test air nozzle 50, the air injection hole 1a, and the air injection path 1b sequentially. At this time, the expansion chamber 2 is of course expanded, and the pressure gauge 80 measures and displays the pressure of air flowing along the inside of the air hose 70.

여기에서 점검원은 압력계(80)가 나타내는 측정값을 육안으로 확인하고 팽창실(2)에서 압력이 누설되는지를 판단할 수 있는 바, 압력계(80)의 측정값이 팽창실(2)로 마땅히 공급되어야 할 압력(약 1.5bar)보다 작다면 팽창실(2)에서 압력이 누설되는 것이다.Here, the inspector can visually check the measured value indicated by the pressure gauge 80 and determine whether the pressure leaks from the expansion chamber 2, and the measured value of the pressure gauge 80 should be the expansion chamber 2. If it is less than the pressure to be supplied (about 1.5 bar), the pressure is leaked from the expansion chamber (2).

한편 압력계(80)의 측정값이 팽창실(2)로 공급되어야 할 압력보다 큰 경우도 있겠다. 이때는 공기 공급장치의 이상으로 팽창실(2)로 과도한 압력이 공급되는 것으로 판단하면 되겠다. 물론 이처럼 과도한 압력이 팽창실(2)로 공급되면 결국 팽창실(2)은 파열되는 바, 이는 개폐밸브(90)를 닫힘 조작하여 공기의 공급을 차단하는 것으로 예방이 가능하게 된다.On the other hand, the measured value of the pressure gauge 80 may be larger than the pressure to be supplied to the expansion chamber 2. In this case, it may be determined that excessive pressure is supplied to the expansion chamber 2 due to an abnormality of the air supply device. Of course, when such excessive pressure is supplied to the expansion chamber 2, the expansion chamber 2 is ruptured, which can be prevented by closing the supply of air by closing the opening and closing valve 90.

이상에서 설명한 바와 같은 본 발명은 승강문의 공기 주입구멍과 에어라인에 각각 삽입되는 시험용 에어노즐 및 시험용 니플, 시험용 에어노즐과 시험용 니플을 연결하는 에어호스, 에어호스에 각각 설치된 압력계 및 개폐밸브로 구성되어 승강문을 열은 상태로 팽창실로의 공기 공급이 가능하므로 시동 오프 상태에서 팽창실의 압력 누설 검사를 이룰 수 있는 이점이 있다.The present invention as described above is composed of a test air nozzle and a test nipple respectively inserted into the air injection hole and the air line of the lifting door, an air hose connecting the test air nozzle and the test nipple, and a pressure gauge and an on-off valve respectively installed in the air hose. Since the air supply can be supplied to the expansion chamber while the lifting door is opened, there is an advantage that the pressure leakage inspection of the expansion chamber can be performed in the start-off state.

또한 압력계를 이용, 과학적인 방식으로 검사하기 때문에 팽창실에서 압력이 누설되는지를 신속ㆍ정확ㆍ간편하게 판별할 수 있으며, 개폐밸브에 의하여 검사 중 안전성을 향상시킬 수 있는 이점도 있다.In addition, since the pressure gauge is used in a scientific way, it is possible to quickly, accurately and easily determine whether the pressure leaks from the expansion chamber, and the on / off valve has the advantage of improving safety during the inspection.
