최근 들어 열차의 속도 향상과 빈도 증가에 따라 철도 연변진동에 의한 영향으로 선로연변에 위치한 학교, 병원, 주민 등의 불편이 날로 가중되고 있으며, 환경의 저해요건 중 진동으로 인한 공해는 인체에 즉각적인 반응을 일으킬 수 있다.Recently, as the speed of trains increases and the frequency increases, inconveniences of schools, hospitals, and residents located along the tracks are increasing day by day due to the effects of railway Yanbian vibrations. May cause
철도연변에서 발생하는 진동은 특히 열차가 도심지나 주택가를 통과할 때는 광범위한 진동공해를 유발할 가능성이 매우 높다.Vibration from railroads is very likely to cause extensive vibration pollution, especially when trains pass through downtown or residential areas.
따라서 이의 해소 방안으로 철도 연변진동의 발생원과 전파경로를 정확히 파악하고 예측하기 위해서는 신뢰성 있는 실측 데이터의 확보와 이러한 데이터와 해석 기법 사이의 유기적인 관계를 구축하는 것이 필요하다.Therefore, in order to solve this problem, it is necessary to secure reliable measurement data and to establish an organic relationship between these data and analysis techniques in order to accurately identify and predict the source and propagation path of railway Yanbian vibration.
이러한 진동데이터의 확보를 위해서 진동센서인 속도계 및 가속도계를 사용하고 있다.In order to secure such vibration data, vibration sensors such as speedometers and accelerometers are used.
상기와 같은 진동센서는 고정장치를 지반에 압입 설치하고 고정장치에 센서를 부착하여 지반진동을 측정하였다.The vibration sensor as described above was installed by press-fitting the fixing device to the ground and attached to the sensor to measure the ground vibration.
이와같이 사용되는 고정장치는 연약지반일 경우 손으로 지반에 압입하여 사용하거나 단단한 지반일 경우 상단부를 해머나 망치 등으로 타격하여 지반에 삽입하여 사용하였다.The fixing device used in this way was used by pressing the ground by hand in the case of soft ground or by inserting it into the ground by hitting the upper end with a hammer or a hammer.
그러나 상기 고정장치는 손으로 압입하여 설치할 경우 극히 일부분의 지반에서만 사용이 가능하였으며 단단한 지반에 사용할 경우 고정장치의 상단부를 해머나 망치로 타격하므로서 고정장치의 상단부가 파손되는 문제점이 있었다.However, when the fixing device is press-installed by hand, only a part of the ground can be used, and when used on a solid ground, the upper end of the fixing device is damaged by hitting the upper end of the fixing device with a hammer or a hammer.
또한 지반에 삽입되는 고정장치의 삽입부분과 지반과 접촉하는 접촉면이 적어 지반과의 일체화가 이루어지지않아 측정데이터의 신뢰성이 떨어지며 센서 고정시 접착제에 의해 접착하므로써 센서 분리시 진동센서가 충격을 받아 수명과 기능이 저하되었다.In addition, since the insertion part of the fixing device inserted into the ground and the contact surface contacting the ground are small, the integration with the ground is not achieved, so the reliability of the measurement data is reduced. And function was degraded.
따라서 접차제를 사용하지 않고 상단부의 상면에 결합수단으로 너트홈을 형성하였으나 고정장치를 지반에 삽입시 상단부를 타격할 때 흙과 같은 이물질이 너트홈에 들어가 센서의 탈 부착이 어려운 문제점이 있었다.Therefore, the nut groove was formed as a coupling means on the upper surface of the upper portion without using a lubricant, but when the fixing device is inserted into the ground, a foreign material such as soil enters the nut groove and it is difficult to attach and detach the sensor.
이에 본 발명은 상기와 같은 종래 기술의 문제점을 감안하여 안출한 것으로 고정장치의 지반과의 접촉면적을 증대시키고 센서와 지반이 일체화를 이루어 지반진동측정의 정확성과 신뢰성을 높일 수 있는 지반진동측정 센서용 고정장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the problems of the prior art as described above. The ground vibration measuring sensor can increase the contact area with the ground of the fixing device and improve the accuracy and reliability of the ground vibration measurement by integrating the sensor and the ground. It is an object of the present invention to provide a fixing device.
본 발명의 또 다른 목적은 어느 지반이라도 캡을 씌워 타격하기 때문에 고정장치의 상단부를 훼손하지 않고 지반에 삽입이 가능한 지반진동측정 센서용 고정장치를 제공 한다.Still another object of the present invention is to provide a ground vibration measuring sensor that can be inserted into the ground without damaging the upper end of the fixing device because it hits the cap on any ground.
상기한 목적을 달성하기 위하여 본 발명은 하측으로 갈수록 좁아지는 몸체의 외경에 돌기를 형성하고 상면에 결합돌기를 형성한 고정몸체와 상기 고정몸체의 상단을 타격하기 위하여 상단부에 형성된 결합돌기를 수용하며 상면과 접촉하도록 하측으로 형성된 수용홈 내경을 단턱지게 형성한 타격캡으로 구성하되 상기 고정몸체의 결합돌기와 결합되도록 중앙에 결합공을 형성하고 상기 결합공 주위로 다양한 크기로 형성된 다수의 센서결합공으로 형성된 고정플레이트를 더 포함하는 것을 특징으로 하는 지반진동측정 센서용 고정장치를 제공한다.In order to achieve the above object, the present invention forms a protrusion on the outer diameter of the body narrowing toward the lower side and accommodates the fixing body formed in the upper end to hit the upper end of the fixed body and the coupling body formed on the upper surface Consists of a blow cap formed in the receiving groove inner diameter formed to be in contact with the upper surface stepped to form a coupling hole in the center to be combined with the engaging projection of the fixed body and formed of a plurality of sensor coupling holes formed in various sizes around the coupling hole It provides a fixing device for the ground vibration measuring sensor further comprises a fixing plate.
따라서 상기와 같은 본 발명은 센서의 탈부착을 용이하게 하여 센서의 수명을 연장하며 지반지동측정의 정확성과 신뢰성을 높이고 고정장치 설치시 상단부의 파손을 방지하여 제품의 효율성을 높일 수 있다.Therefore, the present invention as described above can facilitate the detachable attachment of the sensor to extend the life of the sensor, increase the accuracy and reliability of ground motion measurement, and prevent the damage of the upper end when installing the fixing device can increase the efficiency of the product.

The protrusion 11 is formed in the longitudinal direction, and the coupling protrusion 12 having a spiral is formed on the upper surface 13 of the upper end.
상기 고정몸체(10)의 상단을 타격하기 위하여 타격캡(20)을 형성하되 상기 타격캡(20)은 고정몸체(10)의 상단부에 형성된 결합돌기(12)를 수용하며 상면(13)과 접촉하도록 하측으로 수용홈(21)을 단턱지게 형성한다.A blow cap 20 is formed to strike an upper end of the fixed body 10, but the blow cap 20 receives a coupling protrusion 12 formed at an upper end of the fixed body 10 and contacts the upper surface 13. The receiving groove 21 is formed to be stepped downward.
상기와 같은 고정장치에 다양한 종류의 센서를 고정하기 위하여 중앙에 결합공(31)을 형성한 고정플레이트(30)를 고정몸체(10)의 결합돌기(12)와 체결하고 상기 결합공(31) 주위로 다양한 크기로 형성된 다수의 센서결합공(32)을 형성한다.In order to fix various kinds of sensors to the fixing device as described above, the fixing plate 30 having the coupling hole 31 formed at the center thereof is coupled with the coupling protrusion 12 of the fixing body 10 and the coupling hole 31.
