Description

경사각 측정기{measuring instrument for tilt angle}Measuring instrument for tilt angle

본 발명은 경사각 측정기에 관한 것으로, 더욱 상세하게는 측정 대상물에 측정기를 위치하고 이동바와 눈금자를 이용하여 측정 대상물의 각도를 측정할 수 있도록 한 경사각 측정기에 관한 것이다.The present invention relates to an inclination angle measuring instrument, and more particularly, to an inclination angle measuring instrument capable of measuring an angle of an object to be measured by placing a measuring instrument on a measuring object and using a moving bar and a ruler.

일반적으로 기준면에 대하여 기울어진 정도를 측정하는 장치를 경사각 측정장치라고 한다.Generally, a device for measuring the degree of inclination with respect to a reference plane is referred to as an inclination angle measuring device.

종래의 경사각 측정장치는 측정 대상물이 특히 원형 강관과 같이 곡면일 경우에는 곡면 경사각을 측정하기 어려웠다.It has been difficult to measure the curved surface inclination angle when the object to be measured is a curved surface such as a round steel pipe.

즉, 원형 강관의 경우 기준면을 잡기가 어려웠고 이에따른 기준면과 경사면의 각도를 측정하기 어려웠다.In other words, it was difficult to catch the reference plane in the case of the round steel pipe, and it was difficult to measure the angle between the reference plane and the inclined plane.

또한, 종래의 경우 곡면을 각도기로만 측정함으로 인해 측정이 불명확하여 작업시간이 지연되고 작업도 비능률적이었다.In addition, in the conventional case, measurement of the curved surface was performed only with a protractor, so that the working time was delayed and the operation was inefficient.

상기 경사각 측정기 구성에 대한 작용에 대하여 설명하면 다음과 같다.The operation of the inclination angle measuring device will be described below.

측정 대상물(70)에 경사각 측정기를 위치시킨다.The inclination angle measuring device is placed on the measurement object 70. [

즉, 경사각 측정기의 반지름눈금자(20)와 반지름이동바(50)를 측정 대상물(70)에 위치한다.That is, the radius ruler 20 and the radius moving bar 50 of the tilt angle measuring device are positioned on the measurement object 70.

반지름이동바(50)는 측정 대상물(70)의 반지름의 크기에 따라 조절나사(60)를 조절하여 반지름이동바(50)를 고정시킨다.The radius moving bar 50 adjusts the adjusting screw 60 according to the size of the radius of the measurement object 70 to fix the radius moving bar 50.

예를들어, 반지름의 크기가 2.5m 이면 조절나사(60)를 반시계방향으로 돌려 조절나사(60)를 풀리게 하여 반지름이동바(50)를 상하로 이동하여 반지름눈금자(20)에 표시된 2.5R에 고정시킨다.For example, if the radius is 2.5 m, the adjusting screw 60 is turned counterclockwise to unscrew the adjusting screw 60 to move the radial shifting bar 50 up and down so that the 2.5R .

반지름이동바(50)를 고정시킬때는 조절나사(60)를 시계방향으로 돌려 조절나사(60)를 조인다.When fixing the radius moving bar (50), turn the adjusting screw (60) clockwise to tighten the adjusting screw (60).

반지름이동바(50)에 형성된 일자형상(50h)은 측정 대상물(70)의 반지름 크기를 설정, 고정시 반지름눈금자(20)의 눈금과 일치시킬때의 가늠자이다.The straight shape 50h formed on the radius moving bar 50 is a scale when the radial size of the measurement object 70 is set and coincided with the scale of the radius ruler 20 when fixed.

반지름눈금자(20)는 반지름이동바(50)가 위로 올라갈수록 반지름의 크기가 커져 경사도가 완만하고, 반지름이동바(50)가 아래로 내려갈수록 반지름의 크기가 작아져 경사도가 급하게 된다.As the radius bar 50 is moved upwards, the radius of the radius ruler 20 becomes larger and the radius of the radius bar gradually decreases. As the radius bar 50 is lowered, the radius of the radius bar decreases.

상기와 같이 측정하고자 하는 대상물(70)의 반지름의 크기를 반지름이동바(50)를 이용하여 설정, 고정한 후 각도이동바(30)를 상하로 움직이면서 경사각을 측정하게 된다.The radius of the object 70 to be measured is set and fixed using the radius moving bar 50 and the angle of inclination is measured while the angle moving bar 30 is moved up and down.

이때, 경사각의 측정은 각도이동바(30)의 상면에 형성된 일자형상(30g)이 각도눈금자(10)의 눈금과 일치될 때에 표시된 각도가 측정치가 된다.At this time, the measurement of the tilt angle is made by measuring the angle displayed when the straight line shape 30g formed on the upper surface of the angle shifting bar 30 coincides with the scale of the angle ruler 10.

경사각의 각도는 각도눈금자(10)에 눈금으로 표시되어 있다. 각도눈금자(10)의 상단으로 갈수록 각도의 수치가 낮아지고 하단으로 갈수록 각도의 수치가 높아진다.The angle of the tilt angle is indicated by a scale on the angle scale 10. The value of the angle decreases toward the upper end of the angle ruler 10, and the value of the angle increases toward the lower end.

측정중일 때는 조절나사(40)를 반시계방향으로 돌려 조절나사(40)를 풀어 각도이동바(30)가 각도눈금자(10)의 상하로 움직이게 하고, 측정 후에는 조절나사(40)를 시계방향으로 돌려 조절나사(40)를 조여 각도눈금자(10)의 측정된 눈금을 고정되게 하여 육안으로 확인할 수 있게 한다.When the measuring screw 40 is being measured, the adjusting screw 40 is turned counterclockwise to loosen the adjusting screw 40 to move the angle moving bar 30 up and down the angle ruler 10, To tighten the adjusting screw 40 so that the measured scale of the angle ruler 10 is fixed and visually confirmed.

각도이동바(30)가 각도눈금자(10)상에서 상하로 움직이면 각도눈금자(10)는 좌우로 움직이게 된다.When the angle moving bar 30 moves up and down on the angle ruler 10, the angle ruler 10 moves left and right.

즉, 각도이동바(30)가 각도눈금자(10)상에서 상방향(위)으로 움직이면 각도눈금자(10)는 좌측방향으로 움직이고, 각도이동바(30)가 각도눈금자(10)상에서 하방향(아래)으로 움직이면 각도눈금자(10)는 우측방향으로 움직이게 된다.That is, when the angular movement bar 30 moves upward (upward) on the angular ruler 10, the angular ruler 10 moves in the left direction and the angular movement bar 30 moves downward ), The angle ruler 10 moves to the right.

본 발명의 특징은 경사 형상을 가진 측정기를 곡면으로 이루어진 강관 등의 측정 대상물(70)에 위치하여 측정 대상물(70)의 반지름의 크기에 따라 반지름이동바(50)를 설정, 고정한 후 대상물(70)의 각도를 측정할 수 있도록 하는데 있다.A feature of the present invention is that a measuring device having an inclined shape is placed on a measuring object 70 such as a steel pipe having a curved surface to set and fix the radius moving bar 50 according to the radius of the measuring object 70, ) To measure the angle.

이와같이, 본 발명은 경사 형상을 가진 측정기로 측정 대상물(70)의 각도를 각도눈금자(10)를 통해 측정할 수 있는 것이다.In this way, the present invention can measure the angle of the measurement object 70 with the measuring device having the inclined shape through the angle ruler 10.
