상기 피니언기어(80)는 푸쉬바(70)의 사이에 위치되도록 회전축(81)에 결합되어, 상하면이 각 푸쉬바(70)의 랙기어(71)부에 동시에 치합되므로써, 각 푸쉬바(70)가 전후진 될 때 제자리에서 회전되면서 푸쉬바(70)가 상호 동일한 간격만큼 전후진되도록 지지하여, 상기 상판(20)이 신축 및 위치변동되면, 상기 푸쉬바(70)와 피니언기어(80)의 작용에 의해, 도 4에 도시한 바와 같이, 상기 슬라이드판(40)이 좌우로 슬라이드되면서, 슬라이드판(40)이 상호 연결되는 상판(20) 사이공간의 중간부에 항상 위치되도록 한다.The pinion gear 80 is coupled to the rotation shaft 81 so as to be located between the push bar 70, the upper and lower surfaces are meshed with the rack gear 71 of each push bar 70 at the same time, each push bar 70 When the back and forth are rotated in place to support the push bar 70 is moved forward and backward by the same interval, and when the top plate 20 is stretched and shifted, the push bar 70 and the pinion gear (80) By the action of, as shown in Figure 4, the slide plate 40 is slid left and right, so that the slide plate 40 is always located in the middle of the space between the upper plate 20 to be interconnected.

상기 각도센서(90)는 피니언기어(80)의 각도를 측정하여 상기 제어부로 출력하는 것으로, 상기 제어부는 피니언기어(80)가 회전된 각도와 피니언기어(80)의 지름을 연산하므로써, 푸쉬바(70)가 전후진되는 거리 및 이에따른 상판(20)의 간격을 간접적으로 산출할 수 있다.The angle sensor 90 measures the angle of the pinion gear 80 and outputs it to the control unit. The control unit calculates the angle at which the pinion gear 80 is rotated and the diameter of the pinion gear 80. It is possible to indirectly calculate the distance at which the 70 is moved back and forth and thus the spacing of the upper plate 20.

상기 스프링(100)은 압축스프링(100)으로 구성되어 푸쉬바(70)의 단부와 실린더(60)의 내벽사이에 배치되므로써, 푸쉬바(70)가 실린더(60)의 외부로 돌출되도록 가압한다.The spring 100 is composed of a compression spring 100 is disposed between the end of the push bar 70 and the inner wall of the cylinder 60, thereby pressing the push bar 70 to protrude out of the cylinder 60. .

상기 위치측정센서(110)는 기대(30)에 구비되어, 항상 상판(20) 사이공간의 중간부에 위치되는 슬라이드판(40)의 위치를 측정하므로써, 상판(20)의 공간의 중간부, 즉, 상판(20)의 단부와 단부 사이의 중심점 위치를 측정하여 측정된 위치데이터를 제어유닛(120)으로 전송한다.The position measuring sensor 110 is provided in the base 30, by measuring the position of the slide plate 40 which is always located in the middle of the space between the top plate 20, the middle portion of the space of the top plate 20, That is, the position of the center point between the end and the end of the upper plate 20 is measured and transmits the measured position data to the control unit 120.

상기 제어유닛(120)은 상기 각도센서(90)에서 출력된 각도데이터와 위치측정센서(110)에서 출력된 위치데이터를 수신하여, 각도데이터에서 산출된 상판(20)의 간격과, 상판(20)의 사이공간의 중심점 위치를 산출하고, 이를 재연산하여, 각 상판(20)의 단부위치를 산출하는 기능을 한다. 이때, 온도변화에 따라 각 상판(20)이 신축을 반복함에 따라 각 상판(20)의 단부위치가 변동될 경우, 상기 제어유닛(120)은 이와같은 위치변화를 지속적으로 감시하여, 각 상판(20)의 단부위치변화를 지속적을 확인한다. 그리고, 산출된 각 상판(20)의 단부위치데이터를 상기 디스플레이부(130)와 무선송출장치(150)로 출력함과 동시에, 미리 입력된 안전범위와 각 상판(20)의 단부위치를 비교하여, 상판(20)의 단부가 안전범위를 벗어나 이동될 경우, 상기 디스플레이부(130)와 무선송출장치(150)로 경고신호를 출력함과 동시에, 경보장치(140)를 작동제어하는 기능을 한다.The control unit 120 receives the angle data output from the angle sensor 90 and the position data output from the position measurement sensor 110, the interval of the top plate 20 calculated from the angle data, and the top plate 20 It calculates the position of the center point of the inter-space of the), and by re-computing, the end position of each top plate 20 serves to calculate. At this time, when the end position of each top plate 20 is changed as the top plate 20 repeats the expansion and contraction according to the temperature change, the control unit 120 continuously monitors such a position change, each top plate 20 Check the end position change of) continuously. Then, the calculated end position data of each top plate 20 is outputted to the display unit 130 and the wireless transmitting device 150, and the end position of each top plate 20 is compared with the safety range input in advance. When the end of the upper plate 20 is moved out of the safety range, a warning signal is output to the display unit 130 and the wireless transmission device 150 and at the same time, the alarm device 140 operates and controls. .

상기 디스플레이부(130)는 제어유닛(120)에서 출력된 상판(20)의 단부위치를 디스플레이하여 안전관리자가 육안으로 확인할 수 있도록 한다.The display unit 130 displays the end position of the top plate 20 output from the control unit 120 so that the safety manager can visually check.

상기 무선송출장치(150)는 수신된 단부위치데이터를 무선으로 송출하여, 교량을 관리하는 관리본부 등에서 이를 수신하여 안전관리에 참고할 수 있도록 한다.The wireless transmission device 150 transmits the received end position data wirelessly, so that it can be received by the management headquarters, etc. for managing the bridge to refer to the safety management.

상기 경보장치(140)는 상기 제어부의 제어신호에 의해 작동되므로써, 상판(20)의 단부위치가 안전범위를 벗어날 경우 경보를 출력하여, 안전관리자 또는 교량을 통행하는 차량의 운전자에게 경고를 할 수 있도록 구성된다.The alarm device 140 is operated by the control signal of the control unit, and outputs an alarm when the end position of the top plate 20 is out of the safety range, it can warn the safety manager or the driver of the vehicle passing through the bridge. It is configured to be.

이와같이 구성된 교량용 안전진단시스템의 작용을 설명하면 다음과 같다.The operation of the safety diagnosis system for bridges configured as described above is as follows.

우선, 안전관리자가 본 실시예의 안전진단시스템의 기대(30)를 교각(10)의 상단에 고정한 상태에서, 한쌍으로 구성된 푸쉬바(70)의 단부가 각 상판(20)의 단부에 밀착되도록 설치한 후, 상기 제어유닛(120)을 on 시키면, 상기 제어유닛(120)은 각도센서(90)에서 출력된 각도데이터와 위치측정센서(110)에서 출력된 위치데이터를 수신하여, 이에따라 산출된 각 상판(20)의 단부 위치를 초기위치로 설정하며, 상판(20)의 단부위치가 변동되면 이를 지속적으로 감시하여 상기 디스플레이부(130)와 무선송출장치(150)로 출력한다.First, in a state in which the safety manager secures the base 30 of the safety diagnosis system of the present embodiment to the upper end of the piers 10, the end portions of the pair of push bars 70 are installed to be in close contact with the ends of the upper plates 20. Then, when the control unit 120 is turned on, the control unit 120 receives the angle data output from the angle sensor 90 and the position data output from the position measurement sensor 110, the angle calculated accordingly The end position of the upper plate 20 is set to an initial position, and when the end position of the upper plate 20 is changed, it is continuously monitored and outputted to the display unit 130 and the wireless transmitting device 150.

그리고, 각 상판(20)의 단부위치가 미리 입력된 안전범위를 넘어서면 교량의 안전에 문제가 있음을 알리는 경고신호를 무선송출장치(150)와 디스플레이부(130)로 출력하여 관리자에게 알림과 동시에, 경보장치(140)를 작동시켜 교량을 통행하는 차량의 운전자에게 경고를 할 수 있다.And, if the end position of each top plate 20 exceeds the safety range entered in advance, a warning signal indicating that there is a problem with the safety of the bridge outputs to the wireless transmission device 150 and the display unit 130 to notify the administrator and At the same time, the alarm device 140 may be operated to warn the driver of the vehicle passing through the bridge.

이와같이 구성된 교량용 안전진단시스템은 구성이 간단하며, 상기 푸쉬 바(70)의 단부가 각 상판(20)의 단부에 밀착되도록 설치하면 되므로, 설치 및 관리가 용이한 장점이 있다.The safety diagnosis system for a bridge configured as described above is simple in configuration, and the end of the push bar 70 may be installed to be in close contact with the end of each top plate 20, and thus there is an advantage of easy installation and management.

또한, 상기 기대(30)의 위치를 정확히 설정하지 않아도 상기 슬라이드판(40)이 슬라이드되면서 상판(20) 사이의 공간부 중심에 자동으로 위치되어 초기설정되므로, 세팅이 매우 간편하고 설치위치를 잘못 설정함에 따른 오차가 발생되지 않는 장점이 있다.In addition, even if the position of the base 30 is not set correctly, the slide plate 40 is automatically positioned in the center of the space between the upper plate 20 while being slided and initially set, so the setting is very simple and the installation position is wrong. There is an advantage that the error does not occur by setting.
