타이어 수압 시험 장치{Device for the tire hydraulic testing}Device for the tire hydraulic testing

본 발명은 타이어 수압 시험에 임하는 작업자의 안전 및 시험 데이터의 신뢰도를 향상시킬 수 있는, 개량된 구성의 타이어 수압 시험 장치에 관한 것이다.The present invention relates to a tire hydraulic pressure testing apparatus having an improved configuration, which can improve the safety of the operator working on the tire hydraulic pressure test and the reliability of the test data.

항공기용 타이어 및 그 외 일반 타이어의 정적(靜的)강도를 조사하기 위해, 즉, 타이어의 내압성능을 확인하기 위해, 수압 시험이 넓게 행해지고 있다. 이러한 수압 시험에서는, 일반적으로, 펌프를 사용하여, 타이어의 공기밸브로부터 물을 주입한다. 하지만, 종래의 수압 시험 방식에 의하면, 타이어 내부의 잔류공기를 완전히 빼내지 못한 채 물을 채움으로써, 압축성 유체인 공기가 타이어 내부에서 높은 압력으로 압축되어 있다가, 타이어가 파괴될 때, 엄청난 소음을 발생시킴과 아울러, 높은 압력으로 압축되어 있던 공기의 압력에 의해 타이어 파편이 더 먼 거리까지 흩어지게 하여, 작업자의 부상과 시험장치의 파손을 유발하는 문제가 있었다.Hydraulic tests are widely conducted to investigate static strength of aircraft tires and other general tires, that is, to confirm the pressure resistance performance of tires. In such a hydraulic test, water is generally injected from a tire air valve using a pump. However, according to the conventional hydraulic test method, by filling the water without completely draining the residual air inside the tire, the air, which is a compressive fluid, is compressed at a high pressure inside the tire, and when the tire is destroyed, tremendous noise is generated. In addition, the tire debris was dispersed to a longer distance due to the pressure of the air compressed at a high pressure, causing a worker injury and damage to the test apparatus.

이러한 문제의 해결책으로서, 일본공개특허공보 2000-241304에서는, 타이어의 사이드 월부에 공기빼기 침(針)을 꽂은 상태로 타이어의 내부에 물을 채움과 아울러, 타이어로부터 내부공기가 충분히 배출되었을 때 공기빼기 침을 뽑아낸 후 물을 가압하는 시험 방법이 제안되었다. 그러나 이러한 수압 시험 방식에 의하면, 공 기빼기 침을 꽂는 사이드 월부에 결함이 형성되기 때문에, 시험 중에 발생하는 타이어의 파열이 이 결함으로부터 발생할 가능성이 매우 높고, 또한 결함을 통해 물이 누수 됨으로써 수압을 일정하게 유지할 수 없어 시험 결과를 신뢰하기 어려운 문제가 있다.As a solution to this problem, Japanese Laid-Open Patent Publication No. 2000-241304 fills the inside of the tire with the air bleeding needle inserted in the side wall of the tire, and also provides sufficient air when the internal air is exhausted from the tire. A test method has been proposed to pressurize water after draining. However, according to this hydraulic pressure test method, since a defect is formed in the side wall into which the air draining needle is inserted, the rupture of the tire generated during the test is very likely to occur from this defect, and the water leaks through the defect, thereby increasing the water pressure. There is a problem that can not be kept constant, it is difficult to trust test results.

본 발명은 상술한 종래의 문제점을 해결하기 위해 고안된 것으로서, 시험 타이어가 장착되는 림을 통해, 타이어의 내부공기를 외부로 배출함으로써, 내부공기의 불완전한 배출로 인해 야기되는 타이어 파괴시의 엄청난 폭발음 및 시험 장치나 작업자에게 위협적인 고무 파편의 충격을 감소시켜, 수압 시험에 임하는 작업자의 안전과 시험 데이터의 신뢰도를 향상시킬 수 있는 타이어 수압 시험 장치를 제공하는데 목적이 있다.The present invention has been devised to solve the above-mentioned conventional problems, and through the rim on which the test tire is mounted, by discharging the internal air of the tire to the outside, a huge explosion sound at the time of tire destruction caused by the incomplete discharge of the internal air and It is an object of the present invention to provide a tire hydraulic test apparatus that can reduce the impact of rubber debris that threatens the test apparatus or the operator, thereby improving the safety of the operator and the reliability of the test data.

상술한 기술적 과제를 해결하기 위한 본 발명의 타이어 수압 시험 장치는, 시험 타이어가 장착되는 림(rim)으로서, 입수구 및 배수구가 형성된 수압 시험용 전용 림; 상기 입수구에 일측이 연결되는 입수관; 상기 입수관의 타측이 연결되는 펌프; 상기 펌프에 공급할 물이 저장되는 물공급부; 상기 펌프와 물공급부 사이를 연결하는 급수관; 상기 급수관에 설치되는 급수조절밸브; 상기 배수구에 연결되는 배수관; 상기 배수관에 설치되는 배수조절밸브(90); 및 급수조절밸브와 배수조절밸브의 작동을 제어하는 제어부; 를 포함하여 구성된 것을 특징으로 한다.Tire pressure test apparatus of the present invention for solving the above-described technical problem, a rim (rim) to which the test tire is mounted, the rim for the water pressure test dedicated to the inlet and drain; An inlet pipe having one side connected to the inlet; A pump to which the other side of the water inlet is connected; A water supply unit storing water to be supplied to the pump; A water supply pipe connecting the pump and the water supply unit; A water supply control valve installed at the water supply pipe; A drain pipe connected to the drain hole; A drain control valve (90) installed in the drain pipe; And a control unit for controlling the operation of the water supply control valve and the drain control valve; Characterized in that configured to include.

더 바람직하게는, 상기 배수구와 배수조절밸브 사이의 배수관에, 수압감지부를 설치함으로써, 제어부가 수압감지부로부터 전달받은 검출신호에 대응하여, 상기 급수조절밸브와 배수조절밸브의 작동을 제어하도록 하는 것이다.More preferably, by installing a hydraulic pressure sensing unit in the drain pipe between the drain port and the drain control valve, the controller controls the operation of the water supply control valve and the drain control valve in response to the detection signal received from the hydraulic pressure sensing unit. will be.

여기서, 상기 수압감지부는 압력센서만으로 구성되거나, 이 압력센서와 더불 어 작업자가 눈으로 확인할 수 있는 압력계를 포함하는 형태로 구성될 수 있다.Here, the pressure sensing unit may be configured only with a pressure sensor, or in addition to the pressure sensor may be configured in a form including a pressure gauge that the operator can visually check.

이상과 같이 구성되는 본 발명의 타이어 수압 시험 장치에 의하면, 수압 시험용으로 개발된 림의 급수관을 통해 공급되는 물이 시험 타이어 내에 서서히 채워짐에 따라, 시험 타이어에 채워진 물의 부피만큼, 시험 타이어의 내부공기가 림의 배수관을 통해 바깥으로 빠져나가게 되므로, 시험 타이어의 사이드 월부에 공기빼기 침을 꽂던 종래 방식과 비교하여 볼 때, 시험 타이어의 사이드 월부에 어떤 결함도 생기기 않으므로 누수 문제없이 수압 시험을 실시할 수 있다. 따라서, 수압 시험의 결과에 대한 신뢰도를 높일 수 있다.According to the tire hydraulic test apparatus of the present invention configured as described above, as the water supplied through the water supply pipe of the rim developed for the hydraulic test is gradually filled in the test tire, the internal air of the test tire by the volume of the water filled in the test tire Since it goes out through the drain pipe of the rim, compared with the conventional method of inserting the air bleed needle into the side wall of the test tire, there is no defect in the side wall of the test tire, so that the hydraulic test can be performed without a leak problem. Can be. Therefore, the reliability about the result of a hydraulic test can be improved.

또한, 공기빼기 침을 사용하지 않으므로 침(針) 제거 작업을 수행할 필요가 없을 뿐 아니라 시험 타이어의 다른 부분에 비해 상대적으로 취약한 사이드 월부에 결함을 형성하지 않으므로, 수압 시험 중에 사이드 월부가 파열될 가능성이 현저히 낮아지게 되어 작업자의 안전성을 높일 수 있다.In addition, the use of a bleeding needle eliminates the need to perform a needle removal operation and does not create defects in the sidewalls that are relatively weak compared to other parts of the test tire, so that the sidewalls rupture during the hydraulic test. The possibility is significantly lowered, which increases the safety of the operator.
