호이스트 크레인은 리프트, 권상기(200), 와이어(C)를 포함할 수 있다. 권상기(200)는 수평 빔(10)을 타고 중량물(1)이 놓인 위치 상으로 이동할 수 있다. 권상기(200)는 처음 작업자의 리모콘 조정에 의하여 수평 빔(10)을 타고 중량물(1)의 상부로 이동하게 된다. 이후 미세한 조정을 통하여 중량물(1)의 무게중심 상에 권상기(200)를 위치시킨다. The hoist crane may include a lift, a traction machine 200, and a wire (C). The hoisting machine 200 may move along the horizontal beam 10 to the position where the weight 1 is placed. The hoisting machine 200 is moved to the top of the heavy object 1 along the horizontal beam 10 by the operator's remote control. Then, through fine adjustment, the hoisting machine 200 is positioned on the center of gravity of the heavy object 1.
리프트는 시브(20)와 후크(21)를 포함한다. 시브(20)는 후크(21)와 결합되는 한편, 권상기(200)로부터 연결된 와이어(C)가 감겨진다. 권상기(200)의 동작에 의하여 와이어(C)를 통해 중량물(1)이 상하 이동하게 된다. 리프트는 후크(21)에 매달린 중량물(1)을 들어올리는 것으로서, 보통 중량물(1)의 중앙 부위, 즉 무게중심 부위를 건다. 이때 중량물(1)의 무게중심을 정확히 들어올리지 못하면 중량물(1)의 수평 밸런스가 무너져 중량물(1)이 스윙(swing)이나 스웨이(sway)하게 된다. 중량물(1)이 스윙이나 스웨이하게되면 작업자가 크게 다칠 수 있으므로, 이 경우 권상기(200)가 동작을 멈추는 것이 바람직하다.The lift includes a sheave 20 and a hook 21. While the sheave 20 is coupled to the hook 21, the wire C connected from the hoisting machine 200 is wound. The weight 1 is moved up and down through the wire C by the operation of the hoisting machine 200. The lift is to lift the heavy object 1 suspended from the hook 21, and usually hangs the central portion of the heavy object 1, that is, the center of gravity. At this time, if the center of gravity of the heavy object 1 cannot be accurately lifted, the horizontal balance of the heavy object 1 collapses, causing the heavy object 1 to swing or sway. When the heavy object 1 swings or sways, an operator may be seriously injured. In this case, it is preferable that the hoisting machine 200 stop its operation.
이에 본 발명은 후크(21)가 중량물(1)의 무게중심을 들어올리지 못하는 경우, 또는 중량물(1)이 다른 이유에 의하여 좌우로 흔들리거나 스웨이 되는 경우 이를 감지하여 권상기(200)의 동작을 정지하고자 하는 것이다. Accordingly, the present invention detects when the hook 21 cannot lift the center of gravity of the heavy object 1 or when the heavy object 1 is shaken or swayed from side to side for other reasons to stop the operation of the hoist 200. It's what you want to do.
이를 위하여 본 발명은 센싱유닛(100)과 제어유닛(200)을 포함한다. 센싱유닛(100)은 중량물(1)을 들어올릴 때 중량물(1)의 수평 밸런스를 확인하기 위하여 리프트 상에 센싱유닛(100)을 배치시킨다. 중량물(1)의 수평 밸런스가 무너져 흔들리는 경우(swing 또는 sway)에 중량물(1)을 들고 있는 리프트 또한 흔들리게 된다. 즉 리프트의 흔들림을 감지하여 중량물(1)의 수평 밸런스를 확인하는 것이다.To this end, the present invention includes a sensing unit 100 and a control unit 200. The sensing unit 100 places the sensing unit 100 on the lift to check the horizontal balance of the weight 1 when the weight 1 is lifted. When the horizontal balance of the heavy object 1 collapses and shakes (swing or sway), the lift holding the heavy object 1 also shakes. That is, the shaking of the lift is detected to check the horizontal balance of the heavy object 1.
본 발명은 리프트 상에 센싱유닛(100)을 배치시키는데 보다 정확하게는 리프트의 시브(20) 상에 센싱유닛(100)을 배치시킨다. 이때 센싱유닛(100)은 리프트의 시브(20) 상에 실리콘 등을 통하여 접착될 수 있다. 한편, 센싱유닛(100)이 자석을 포함하여 철로 이루어진 시브(20)에 자력으로 탈부착할 수도 있다. In the present invention, the sensing unit 100 is disposed on the lift, more precisely, the sensing unit 100 is disposed on the sheave 20 of the lift. At this time, the sensing unit 100 may be attached to the sheave 20 of the lift through silicon or the like. On the other hand, the sensing unit 100 may be attached to and detached from the sheave 20 made of iron by magnetic force including a magnet.
이 경우, 자력에 의하여 센싱유닛(100)을 탈부착 할 수 있어, 필요한 경우에 센싱유닛(100)을 부착하여 중량물(1)의 밸런스를 센싱할 수 있고, 또 불필요한 경우에는 센싱유닛(100)을 탈착하거나 제거하고, 센싱유닛(100)없이 리프트만을 사용하여 중량물(1)을 들어올리거나 내릴 수 있다. In this case, the sensing unit 100 can be attached or detached by magnetic force, and if necessary, the sensing unit 100 can be attached to sense the balance of the heavy object 1, and if unnecessary, the sensing unit 100 can be attached. It is possible to detach or remove and lift or lower the heavy object 1 using only a lift without the sensing unit 100 .
탈부착을 위하여 본 발명은 바디부(130)를 포함할 수 있다. 바디부(130)는 탄성지지부(122)를 지지하면서, 자석을 포함하여 리프트에 자력에 의하여 탈부착될 수 있다.For attaching and detaching, the present invention may include a body part 130. The body part 130 may include a magnet while supporting the elastic support part 122 and may be detached from the lift by magnetic force.
*본 발명은 제어유닛(200)을 포함한다. 제어유닛(200)은 센싱유닛(100)에서 감지한 중량물(1)의 밸런스(수평 밸런스)를 수신하고 수신된 중량물(1)의 밸런스에 따라 권상기(200)의 동작을 제어하게 된다. 권상기(200)는 와이어(C)를 통하여 리트프를 상하로 이동시키는 동력을 제공한다.* The present invention includes a control unit (200). The control unit 200 receives the balance (horizontal balance) of the heavy object 1 detected by the sensing unit 100 and controls the operation of the traction machine 200 according to the received balance of the heavy object 1. The hoisting machine 200 provides power to move the lift up and down through the wire (C).
제어유닛(200)은 권상기(200)의 동작을 제어함으로써 중량물(1)을 들어올리거나 내릴 때 중량물(1)의 밸런스가 무너진 경우 리프트를 정지시킬 수 있게 된다.The control unit 200 controls the operation of the hoisting machine 200 to stop the lift when the weight 1 is out of balance when the weight 1 is lifted or lowered.
센싱유닛(100)과 제어유닛(200)은 무선으로 통신할 수 있는 통신모듈(102)을 각각 구비한다. 즉 센싱유닛(100)에서 측정된 중량물(1)의 밸런스(리프트의 밸런스)가 제어유닛(200)으로 전달되면, 이를 전달받은 제어유닛(200)은 권상기(200)의 동작을 제어할 수 있다. 이떼 센싱유닛(100)은 일정 크기 이상으로 리프트의 움직임이 감지된 경우에만 제어유닛(200)에 신호를 전달하도록 설정될 수 있다. 즉, 리프트의 움직임이 큰 경우에만 제어유닛(200)에 신호를 전달하고, 이를 전달받은 제어유닛(200)이 권상기(200)의 동작을 멈추게 할 수 있다. The sensing unit 100 and the control unit 200 each include a communication module 102 capable of wireless communication. That is, when the balance (lift balance) of the weight 1 measured by the sensing unit 100 is transmitted to the control unit 200, the control unit 200 that receives it can control the operation of the hoisting machine 200 . The teeth sensing unit 100 may be configured to transmit a signal to the control unit 200 only when the movement of the lift is detected to a certain extent or more. That is, only when the movement of the lift is large, a signal is transmitted to the control unit 200, and the control unit 200 receiving the signal can stop the operation of the hoisting machine 200.
한편, 모든 리프트의 흔들림을 제어유닛(200)에 전달하고, 이를 전달받은 제어유닛(200)이 판단하여 권상기(200)의 동작을 멈출수도 있다. On the other hand, shaking of all lifts is transmitted to the control unit 200, and the control unit 200 that receives the shaking may determine and stop the operation of the hoisting machine 200.
도 1은 본 발명에 따른 센싱유닛(100)을 나타낸 도면이다. 도 1에 도시된 바와 같이 본 발명에 따른 센싱유닛(100)은 중량부(110), 센서(101), 탄성지지부(121)를 포함한다. 1 is a diagram showing a sensing unit 100 according to the present invention. As shown in FIG. 1 , the sensing unit 100 according to the present invention includes a weight part 110 , a sensor 101 , and an elastic support part 121 .
중량부(110)는 일정 무게 이상을 갖는 중량을 갖는 물체를 의미한다. 중량부(110)는 탄성지지부(121)에 의하여 지지되는데, 탄성지지부(121)의 일단은 리프트에 고정되고, 타단에는 중량부(110)를 지지함으로써 리프트의 흔들림에 따라 고정되지 않은 중량부(110)도 흔들리게 되고, 이에 따라 탄성지지부(121)는 중량부(110)의 흔들림에 따라 휘어지게 된다. The weight part 110 means an object having a weight having a certain weight or more. The weight part 110 is supported by the elastic support part 121. One end of the elastic support part 121 is fixed to the lift, and the other end supports the weight part 110, so that the weight part that is not fixed according to the shaking of the lift ( 110) is also shaken, and accordingly, the elastic support part 121 is bent according to the shaking of the weight part 110.
중량부(110) 내부에는 센서(101)와 통신모듈(102)을 포함할 수 있다. 물론 센서(101)와 통신모듈(102)에 전력을 제공하는 배터리(미도시)가 내장될 수 있다.The inside of the weight part 110 may include a sensor 101 and a communication module 102 . Of course, a battery (not shown) providing power to the sensor 101 and the communication module 102 may be incorporated.
센서(101)는 중량부(110)의 흔들림을 감지하는 것으로서 각속도를 측정하여 중량부(110)의 흔들림을 감지할 수 있다. 각속도 측정기로 자이로 센서(101)를 포함할 수 있다.The sensor 101 detects shaking of the weight part 110 and may detect shaking of the weight part 110 by measuring an angular velocity. The gyro sensor 101 may be included as an angular velocity measurer.
*도 2는 본 발명에 따른 제어유닛(200)이 센싱유닛(100)에서의 정보를 통해 권상기(200)를 제어하는 것을 나타낸 도면이다.* Figure 2 is a view showing that the control unit 200 according to the present invention controls the hoisting machine 200 through information from the sensing unit 100.
도 2에 도시된 바와 같이 센서(101)에서 측정된 중량부(110)의 흔들림에 대한 정도가 중량부(110) 내의 통신모듈(102)을 거쳐 제어유닛(200)에 전달될 수 있다. As shown in FIG. 2 , the degree of shaking of the weight part 110 measured by the sensor 101 may be transmitted to the control unit 200 via the communication module 102 in the weight part 110 .
제어유닛(200)은 센싱유닛(100)에서 전달된 중량부(110)의 흔들림의 정도에 따라 권상기(200)를 제어할 수 있다. 물론 앞서 설명한 것처럼 센싱유닛(100)은 일정정도 이상의 흔들림의 경우에만 제어유닛(200)에 이러한 신호를 전달할 수 있고, 이 경우 제어유닛(200)은 흔들림의 크기에 대한 판단없이 바로 권상기(200)를 제어하여 권상기(200)의 동작을 멈추게 할 수도 있다.The control unit 200 may control the hoisting machine 200 according to the degree of shaking of the weight part 110 transmitted from the sensing unit 100 . Of course, as described above, the sensing unit 100 can transmit such a signal to the control unit 200 only in the case of shaking of a certain degree or more, and in this case, the control unit 200 directly moves the traction machine 200 without determining the size of the shaking. It may be possible to stop the operation of the traction machine 200 by controlling.
탄성지지부(121)는 탄성을 갖으며 중량부(110)를 지지하게 된다. 탄성지지부(121)의 일단은 리프트에 고정되고, 타단은 중량부(110)와 결합하여 중량부(110)를 지지하게 된다. 중량물(1)이 흔들리면 중량물(1)을 지지하면서 들고 있는 리프트가 흔들리고, 리프트가 흔들리면 탄성지지부(121)에 짖된 중량부(110)가 흔들리게 된다. 결국 중량부(110)의 흔들림을 측정하여 중량물(1)의 흔들림을 감지하게 되는 것이다.The elastic support part 121 has elasticity and supports the weight part 110 . One end of the elastic support part 121 is fixed to the lift, and the other end is coupled with the weight part 110 to support the weight part 110 . When the heavy object 1 is shaken, the lift held while supporting the heavy object 1 shakes, and when the lift shakes, the weight portion 110 attached to the elastic support portion 121 shakes. Eventually, the shaking of the heavy object 1 is sensed by measuring the shaking of the weight part 110 .
이때 탄성지지부(121)는 스프링일 수도 있고, 탄성을 갖는 바(bar)형상으로 형성될 수도 있다. 중량부(110)를 지지하면서 외력에 의하여 흔들릴 수 있는 재질은 모두 포함될 수 있다. At this time, the elastic support part 121 may be a spring or may be formed in the shape of a bar having elasticity. All materials that can be shaken by an external force while supporting the weight portion 110 may be included.
도 3은 본 발명에 따른 호이스트 크레인 밸런스 감지시스템을 나타낸 도면이고, 도 4는 본 발명에 따라 중량물(1)의 밸런스가 유지되지 않는 경우 권상기(200)의 동작이 제어되는 것을 나타낸 도면이다. 3 is a view showing a hoist crane balance detection system according to the present invention, and FIG. 4 is a view showing that the operation of the hoist 200 is controlled when the balance of the weight 1 is not maintained according to the present invention.
도 3에 도시된 바와 같이 호이스트 크레인이 중량물(1)을 들지 않는 경우 권상기(200)로부터의 와이어(C)와 와이어(C)에 결합된 리프트는 지면에 수직을 이루고 있다. As shown in FIG. 3, when the hoist crane does not lift the heavy object 1, the wire C from the hoisting machine 200 and the lift coupled to the wire C are perpendicular to the ground.
도 4에 도시된 바와 같이 리프트가 중량물(1)의 무게중심 부분을 정확하게 들지 못하는 경우 중량물(1)이 스윙이나 스웨이하게 되고, 이에 따라 센싱유닛(100)의 탄성지지부(121)가 휘어져 중량부(110)가 흔들리게 된다. 이때 센서(101)가 중량부(110)가 흔들림을 측정하게 되고, 측정된 흔들림의 정도를 제어유닛(200)에 전송하게 된다.As shown in FIG. 4 , when the lift does not accurately lift the center of gravity of the heavy object 1, the heavy object 1 swings or sways, and accordingly, the elastic support part 121 of the sensing unit 100 is bent and the weight part (110) will shake. At this time, the sensor 101 measures the shaking of the weight part 110 and transmits the measured degree of shaking to the control unit 200 .
도 5는 본 발명에 따라 중량물(1)의 밸런스가 유지되지 않는 경우 센싱유닛(100)에서 빛을 발광하는 것을 나타낸 도면이고, 도 6은 본 발명에 따라 중량물(1)의 밸런스가 유지되지 않는 경우 센싱유닛(100)에서 음향을 송출하는 것을 나타낸 도면이다.5 is a view showing that the sensing unit 100 emits light when the balance of the heavy object 1 is not maintained according to the present invention, and FIG. 6 is a view showing that the balance of the heavy object 1 is not maintained according to the present invention. In this case, it is a diagram showing that sound is transmitted from the sensing unit 100.
도 5 및 도 6에 도시된 바와 같이, 중량물(1)의 수평 밸런스가 무너지게 되는 경우, 즉 중량부(110)가 크게 흔들리는 경우 중량부(110)는 빛을 발광하거나 또는 음향을 송출할 수 있는 구성을 포함할 수 있다.As shown in FIGS. 5 and 6, when the horizontal balance of the heavy object 1 is broken, that is, when the weight part 110 is greatly shaken, the weight part 110 may emit light or emit sound. configuration may be included.
이를 위하여 빛을 발광하는 발광부 및 제어부를 더 포함할 수 있다. 제어부는 센서(101)에서 감지된 중량부(110)의 움직임양(흔들림양)이 기설정된 움직임양을 초과하는 경우 발광부가 빛을 발광하도록 제어할 수 있다.To this end, a light emitting unit for emitting light and a control unit may be further included. The control unit may control the light emitting unit to emit light when the movement amount (shake amount) of the weight unit 110 detected by the sensor 101 exceeds a preset movement amount.
한편, 음향을 송출하는 음향솔출부 및 제어부를 더 포함할 수 있다. 제어부는 센서(101)에서 감지된 중량부(110)의 움직임양(흔들림양)이 기설정된 움직임양을 초과하는 경우 음향송출부가 음향을 송출하도록 제어할 수 있다.On the other hand, it may further include a sound solution unit and a control unit for transmitting sound. The controller may control the sound transmission unit to emit sound when the movement amount (shake amount) of the weight unit 110 detected by the sensor 101 exceeds a predetermined movement amount.
도 7은 본 발명의 다른 실시예에 따른 호이스트 크레인 밸런스 감지시스템을 나타낸 도면이고, 도 8은 본 발명의 다른 실시예에 따라 중량물(1)의 밸런스가 유지되지 않는 경우 권상기(200)의 동작이 제어되는 것을 나타낸 도면이다. 7 is a view showing a hoist crane balance detection system according to another embodiment of the present invention, and FIG. 8 is a view showing the operation of the hoist 200 when the balance of the weight 1 is not maintained according to another embodiment of the present invention. A diagram showing what is being controlled.
도 7 내지 도 8에 도시된 바와 같이 본 발명의 다른 실시예에 따른 센서(S)는 중량부(110) 내부가 아닌 외부에 형성될 수 있다. 즉, 센서(S)가 중량부(110)를 둘러싸도록 형성될 수 있다. 중량부(110)가 스웨이 되는 경우 중량부(110)가 센서(S)에 접촉될 수 있도록 구성되는 것이다.As shown in FIGS. 7 and 8 , the sensor S according to another embodiment of the present invention may be formed outside the weight part 110 instead of inside. That is, the sensor S may be formed to surround the weight part 110 . When the weight portion 110 is swayed, the weight portion 110 is configured to be in contact with the sensor (S).
중량부(110) 내부에 아닌 외부의 접촉 센서(S)를 통하여 중량부(110)의 흔들림을 체크하는 것이다. 중량부(110)를 지지하는 탄성지지부(122)의 탄성계수의 크기 및 중량부(110)와 센서(S) 사이의 거리를 통하여 권상기(200)의 동작을 멈추게 하기 위한 중량부(110)의 흔들림 정도를 조절할 수 있다. 예를 들어 탄성계수의 크기를 키우면 권상기(200)의 동작을 멈추게 하기 위한 중량부(110)의 흔들림의 정도는 커져야 한다. The shaking of the weight part 110 is checked through the external contact sensor S, not inside the weight part 110. The size of the modulus of elasticity of the elastic support part 122 supporting the weight part 110 and the distance between the weight part 110 and the sensor S of the weight part 110 for stopping the operation of the hoisting machine 200 You can adjust the degree of shaking. For example, if the magnitude of the modulus of elasticity is increased, the degree of shaking of the weight part 110 for stopping the operation of the hoisting machine 200 should increase.
마찬가지로 중량부(110)와 접촉 센서(S) 사이의 거리가 멀어지면 권상기(200)의 동작을 멈추게 하기 위한 중량부(110)의 흔들림의 정도는 커져야 한다. 이와 같이 탄성지지부(122)의 탄성계수의 크기, 그리고 중량부(110)와 센서(S) 사이의 거리를 조절하여 권상기(200) 제어를 위한 흔들림 정도를 조절할 수 있다. Similarly, when the distance between the weight part 110 and the contact sensor S is increased, the degree of shaking of the weight part 110 for stopping the operation of the hoisting machine 200 should increase. In this way, it is possible to adjust the degree of shaking for controlling the hoisting machine 200 by adjusting the size of the modulus of elasticity of the elastic support part 122 and the distance between the weight part 110 and the sensor S.
