Description

휴대용 고주파 바이브레이터portable high frequency vibrator
본 발명은 휴대용 고주파 바이브레이터에 관한 것으로서, 보다 상세하게는 고주파 진동을 발생시키는 고주파 바이브레이터를 휴대용으로 구비하여 타설된 콘크리트 내의 기포를 간편하게 제거하는 한편 골재를 균일하게 분포시키는 휴대용 고주파 바이브레이터에 관한 것이다.The present invention relates to a portable high-frequency vibrator, and more specifically, to a portable high-frequency vibrator that generates high-frequency vibration, so as to easily remove air bubbles in poured concrete and evenly distribute aggregate.
일반적으로, 타설용 콘크리트 몰탈 내에는 수많은 미세 기포가 존재한다. 이러한 콘크리트 몰탈은 운반 과정뿐 아니라 콘크리트 타설 시에도 존재하게 되며, 이러한 기포로 인해 양생된 콘크리트의 강도가 현저히 저하된다. 따라서, 콘크리트 타설 시 내부에 존재하는 기포를 제거하는 작업이 필수적으로 수반되어야 한다.Generally, numerous fine bubbles exist in concrete mortar for pouring. Such concrete mortar is present not only during the transportation process but also during the pouring of concrete, and the strength of the cured concrete is significantly reduced due to these air bubbles. Therefore, when pouring concrete, it is essential to remove the air bubbles present inside.
기포를 제거하는 장치는 등록실용 제20-0410704호, 제20-0301528호에 나타난 바와 같이 동력을 발생시키는 원동기; 원동기가 고정되며 작업자의 등에 짊어질 수 있도록 어깨끈이 구비된 프레임; 내부에 공간을 가지는 기다란 바이브레이터 봉; 원동기와 바이브레이터 봉 간을 연결하는 플랙시블 관; 바이브레이터 봉의 내부에 설치되는 모터; 모터 축에 고정되어 진동을 발생시키는 편심체;로 이루어진다.The device for removing air bubbles includes a prime mover that generates power as shown in Registration Office Nos. 20-0410704 and 20-0301528; A frame on which the prime mover is fixed and which is provided with a shoulder strap so that it can be carried on the worker's back; A long vibrator wand with a space inside; Flexible pipe connecting the prime mover and the vibrator rod; A motor installed inside the vibrator rod; It consists of an eccentric body that is fixed to the motor shaft and generates vibration.
이와 같은 구조로 이루어진 종래의 바이브레이터는 편심체가 회전하면서 진동을 발생시키고 이를 내장한 바이브레이터 봉에도 진동이 발생함으로써 타설되는 콘크리트 몰탈에 바이브레이터 봉을 삽입하면 바이브레이터 봉 주변의 콘크리트 몰탈이 흔들리면서 그 내부에 존재하는 기포가 부력에 의해 상승하여 제거된다.A conventional vibrator with such a structure generates vibration as the eccentric rotates, and vibration is also generated in the vibrator rod embedded in it. When the vibrator rod is inserted into the concrete mortar being poured, the concrete mortar around the vibrator rod shakes, causing vibrations present inside it. The air bubbles rise and are removed by buoyancy.
하지만, 종래의 바이브레이터는 원동기를 이용하기 때문에, 원동기에 상용 전원을 공급하기 위한 전선이 연결되어야 하므로 감전 사고의 우려와 더불어 바이브레이터의 이동에 많은 제약이 따르는 문제가 있다.However, since the conventional vibrator uses a motor, a wire for supplying commercial power to the motor must be connected, which poses a problem of many restrictions on the movement of the vibrator as well as the risk of electric shock.
그리고, 원동기에는 이의 작동을 위해 인버터를 비롯한 다양한 추가 부품들이 구비되어야 하기 때문에, 작업자가 메는 원동기의 무게가 중량화될 수밖에 없고, 원동기의 무게로 인해 이동이 힘들고, 콘크리트 몰탈에서 기포를 제거하는 작업 역시도 번거롭게 이루어져 작업성이 저하되는 단점이 있다.In addition, since the prime mover must be equipped with various additional parts, including an inverter, for its operation, the weight of the prime mover carried by the worker is bound to increase, the weight of the prime mover makes it difficult to move, and the task of removing air bubbles from concrete mortar is difficult. It is also cumbersome and has the disadvantage of lowering workability.

따라서, 본 발명은 전술한 바와 같은 종래기술의 문제점을 해결하기 위해 안출된 것으로, 바이브레이터 봉을 통해 발산되는 고주파 진동을 밸런스 유지된 상태로 발생시킴으로써 모터의 부하를 줄일 수 있고, 이에 따라 모터에 공급되는 전원을 배터리로 공급할 수 있게 되므로 바이브레이터가 경량화되어 간편하게 휴대 및 이동할 수 있는 휴대용 고주파 바이브레이터를 제공하는데 그 목적이 있다.Therefore, the present invention was developed to solve the problems of the prior art as described above, and the load on the motor can be reduced by generating high-frequency vibration emitted through the vibrator rod in a balanced state, thereby reducing the load supplied to the motor. The purpose is to provide a portable high-frequency vibrator that can be easily carried and moved by making the vibrator lighter because the power can be supplied by a battery.

그리고, 회전축의 편심부에는 함몰된 요홈부가 형성되어 편심부를 분할하도록 구비될 수 있다.Additionally, a recessed groove may be formed in the eccentric portion of the rotating shaft to divide the eccentric portion.
이에 더하여, 회전축의 요홈부 전방에는 제1 편심부가 형성되고, 요홈부 후방에는 제2 편심부가 형성되되, 전방의 제1 편심부가 후방의 제2 편심부보다 더 길게 형성될 수 있다.In addition, a first eccentric part is formed in front of the groove of the rotation shaft, and a second eccentric part is formed behind the groove, and the front first eccentric part may be formed longer than the rear second eccentric part.
또한, 요홈부에서의 축은 회전축과 동일 직경으로 형성될 수 있다.Additionally, the axis in the groove may be formed to have the same diameter as the rotation axis.
본 발명의 휴대용 고주파 바이브레이터에 따르면, 바이브레이터 봉 내에 구비되는 회전축의 전,후 측에서 밸런스 유지된 상태로 고주파 진동이 발생됨으로써 회전축의 고주파 진동에 의한 모터의 부하가 최소화되어 모터의 출력 저하를 방지할 수 있고, 이에 의해 전력 소모가 적으므로 상용 전원을 배터리로 공급할 수 있게 되므로 바이브레이터가 경량화되어 바이브레이터의 휴대 및 이동이 간편한 효과가 있다.According to the portable high-frequency vibrator of the present invention, high-frequency vibration is generated in a balanced state on the front and rear sides of the rotating shaft provided in the vibrator rod, thereby minimizing the load on the motor due to high-frequency vibration of the rotating shaft to prevent a decrease in the output of the motor. As a result, power consumption is low, so commercial power can be supplied through a battery, which makes the vibrator lighter, making it easier to carry and move the vibrator.

그리고, 회전축(110)의 표면에는 일측으로 돌출된 편심부가 형성되고, 이 편심부에는 함몰된 요홈부(113)가 형성되어 편심부를 분할하게 된다.Then, an eccentric part protruding to one side is formed on the surface of the rotation shaft 110, and a recessed groove 113 is formed in this eccentric part to divide the eccentric part.
즉, 회전축(110)의 요홈부(113) 전방에는 제1 편심부(111)가 형성되고, 요홈부(113) 후방에는 제2 편심부(112)가 형성되되, 전방의 제1 편심부(111)가 후방의 제2 편심부(112)보다 더 길게 형성된다. 바람직하게는 제1 편심부(111)와 제2 편심부(112)가 2:1의 비율로 형성된다.That is, a first eccentric portion 111 is formed in front of the groove 113 of the rotation shaft 110, and a second eccentric portion 112 is formed behind the groove 113, and the front first eccentric portion ( 111) is formed to be longer than the rear second eccentric portion 112. Preferably, the first eccentric portion 111 and the second eccentric portion 112 are formed in a ratio of 2:1.
이는, 바이브레이터 봉(100)의 전방에 위치되는 제1 편심부(111)를 후방에 위치되는 제2 편심부(112)보다 더 길게 형성함으로써 회전축(110)의 제1 편심부(111)에 의해 바이브레이터 봉(100)의 전방에서 후방보다는 큰 진동 폭을 발생시켜 진동의 외부 발산 효과를 극대화하기 위한 것이나, 후방의 제2 편심부(112)에 의해 제1 편심부(111)에서 발생되는 큰 진동 폭을 일정 폭으로 상쇄시켜 밸런스를 유지한 진동을 외부로 발산토록 한 것이다.This is by forming the first eccentric part 111 located in the front of the vibrator rod 100 to be longer than the second eccentric part 112 located in the rear, so that the first eccentric part 111 of the rotating shaft 110 This is to maximize the external dissipation effect of vibration by generating a larger vibration amplitude at the front of the vibrator rod 100 than at the rear, but the large vibration generated at the first eccentric portion 111 by the second eccentric portion 112 at the rear The width is offset by a certain width to radiate the balanced vibration to the outside.
따라서, 상기와 같이 제1,2 편심부(111)(112)에 의해 밸런스가 유지된 채로 발생되는 진동은 바이브레이터 봉(100)의 전체에서 발생되는 효과를 가지므로 배터리(400)의 소모가 적고 콘크리트 몰탈에서 기포 제거의 효율이 향상되는 이점이 있다.Therefore, the vibration generated while the balance is maintained by the first and second eccentric parts 111 and 112 as described above has an effect generated throughout the vibrator rod 100, so the consumption of the battery 400 is reduced. There is an advantage that the efficiency of removing air bubbles from concrete mortar is improved.
한편, 상기와 같이 제1,2 편심부(111)(112)를 분할하는 요홈부(113)는 요홈부(113)의 축이 회전축(110)과 동일 직경을 갖도록 형성된다.Meanwhile, the groove portion 113 dividing the first and second eccentric portions 111 and 112 as described above is formed so that the axis of the groove portion 113 has the same diameter as the rotation axis 110.
따라서, 회전축(110)의 회전시 제1,2 편심부(111)(112)에 의해서만 고주파 진동이 일정하게 발생될 수 있다.Therefore, when the rotation shaft 110 rotates, high-frequency vibration can be constantly generated only by the first and second eccentric parts 111 and 112.
이를 위해, 도 5를 참조하면, 제1,2 편심부(111)(112)는 그 일부가 전축(110)의 축 중심으로부터 동일 반경(R)을 갖도록 형성되도면서 축반경(R)보다 제1,2 편심부(111)(112)의 반경(R1, R2)이 더 크도록 형성함으로써 달성된다.To this end, referring to FIG. 5, some of the first and second eccentric portions 111 and 112 are formed to have the same radius (R) from the axial center of the front axis 110 and are smaller than the axis radius (R). This is achieved by forming the radii (R1, R2) of the 1 and 2 eccentric portions 111 and 112 to be larger.
이때, 앞서 제1,2 편심부(111)(112)의 길이에 대하여 언급하였으나, 그 반경을 달리함으로써, 즉, 제1 편심부(111)의 반경(R1)을 제2 편심부(112)의 반경(R2)보다 크게함으로서도 달성될 수 있다. 물론, 반경 및 길이를 조합하는 것도 가능하다. At this time, the lengths of the first and second eccentric parts 111 and 112 were mentioned above, but by varying the radii, that is, the radius R1 of the first eccentric part 111 is changed to the second eccentric part 112. It can also be achieved by making it larger than the radius (R2) of. Of course, it is also possible to combine radius and length.
또한, 상기와 같은 회전축(110)은 바이브레이터 봉(100)의 내측에 베어링(115)을 매개로 하여 회전 가능하게 구비되는 바, 베어링(115)은 회전축(110)의 양측 단부에 위치 고정된 상태로 결합되어 회전축(110)의 회전을 가이드하게 된다.In addition, the rotation shaft 110 as described above is rotatably provided on the inside of the vibrator rod 100 via bearings 115, and the bearings 115 are positioned and fixed at both ends of the rotation shaft 110. It is coupled to guide the rotation of the rotation axis 110.
이때, 회전축(110)에는 베어링(115)을 제1,2 편심부(111)(112)와 이격시켜 상호 간섭을 피하기 위한 방지턱(114)이 구비되고, 방지턱(114)은 회전축(110)에서 제1,2 편심부(111)(112) 측으로 각각 단턱지게 돌출 형성된다.At this time, the rotation shaft 110 is provided with a bump 114 to separate the bearings 115 from the first and second eccentric parts 111 and 112 to avoid mutual interference, and the bump 114 is located on the rotation shaft 110. The first and second eccentric portions 111 and 112 are formed to protrude stepwise, respectively.
이로써, 베어링(115)이 방지턱(114)에 걸림됨으로써 베어링(115)과 제1,2 편심부(111)(112) 간의 접촉은 원천 차단되어 간섭을 피할 수 있게 된다.As a result, the bearing 115 is caught on the bump 114, thereby completely blocking contact between the bearing 115 and the first and second eccentric parts 111 and 112, thereby avoiding interference.
또한, 상기와 같은 제1,2 편심부(111)(112)는 도 5에서와 같이 외주면의 대부분이 바이브레이터 봉(100)의 내주면에 접하는 정원으로 형성될 수 있고, 또는 도 6에서와 같이 외주면의 양측이 절삭되어 제거된 캠 형상으로 형성되어 제1,2 편심부(111)(112)의 상단부만이 바이브레이터 봉(100)의 내주면에 접하도록 구비할 수도 있다. 특히, 후자의 경우는 회전축(110)을 바이브레이터 봉(100)에 용이하게 삽입하여 결합할 수 있게 된다.In addition, the first and second eccentric parts 111 and 112 as described above may be formed as a circle in which most of the outer peripheral surface is in contact with the inner peripheral surface of the vibrator rod 100, as shown in FIG. 5, or the outer peripheral surface may be in contact with the inner peripheral surface of the vibrator rod 100, as shown in FIG. It may be formed in a cam shape with both sides cut and removed so that only the upper ends of the first and second eccentric parts 111 and 112 are in contact with the inner peripheral surface of the vibrator rod 100. In particular, in the latter case, the rotation shaft 110 can be easily inserted and coupled to the vibrator rod 100.
따라서, 상기와 같이 회전축(110)의 전,후 측에 제1,2 편심부(111)(112)를 각각 구성함으로써 회전축(110)에 의한 고주파 진동이 밸런스 유지된 상태로 발생되므로 모터(120)의 부하를 최소화할 수 있어 모터(120)의 출력 저하를 방지할 수 있고, 이에 따라 전력 소모가 적어 배터리(400)에 의한 전원 공급이 가능하게 되므로 바이브레이터를 경량화할 수 있어 바이브레이터의 휴대 및 이동이 간편하게 된다.Therefore, by forming the first and second eccentric parts 111 and 112 on the front and rear sides of the rotating shaft 110, respectively, as described above, the high-frequency vibration caused by the rotating shaft 110 is generated in a balanced state, so that the motor 120 ) can be minimized, thereby preventing a decrease in the output of the motor 120, and as a result, power consumption is reduced and power can be supplied by the battery 400, so the vibrator can be lightweight, allowing the vibrator to be carried and moved. This becomes easy.
그리고, 회전축(110)에서 밸런스 유지된 고주파 진동에 의해 바이브레이터 봉(100) 전체가 진동되는 효과를 가지므로 콘크리트 몰탈에서 기포를 효율적으로 제거할 수 있게 된다.In addition, since the entire vibrator rod 100 has the effect of vibrating due to the high-frequency vibration balanced on the rotating shaft 110, air bubbles can be efficiently removed from the concrete mortar.
한편, 상기와 같은 바이브레이터 봉(100)의 고주파 진동은 바이브레이터 봉(100)에 연결캡(102)과 호스(200)로서 연결된 컨트롤러(300)에 의해 제어된다. 이때, 호스(200)는 플렉시블한 재질이면서도 방수 재질로 구비됨이 바람직하다.Meanwhile, the high-frequency vibration of the vibrator rod 100 as described above is controlled by a controller 300 connected to the vibrator rod 100 through a connection cap 102 and a hose 200. At this time, the hose 200 is preferably made of a flexible and waterproof material.
그리고, 컨트롤러(300)에는 케이블(310)에 의해 배터리(400)가 연결됨으로써 배터리(400)의 전원이 컨트롤러(300)를 통해 모터(120)에 공급될 수 있다.In addition, the battery 400 is connected to the controller 300 through the cable 310, so that power from the battery 400 can be supplied to the motor 120 through the controller 300.
또한, 배터리(400)는 휴대기구(500)를 통해 작업자가 멘 상태로 휴대하여 이동할 수 있게 된다.In addition, the battery 400 can be carried and moved by the worker through the portable device 500.
이러한 휴대기구(500)는 후면에 배터리(400)가 고정되어 장착되는 한편 그 전면은 작업자의 등에 부착되어 구비되는 등받이(510)와, 등받이(510)의 전면 양측에서 등받이(510)의 상부와 하부를 연결하도록 구비되어 작업자의 어깨에 걸림되는 어깨밴드(520)와, 등받이(510)의 전면 하부에서 등받이(510)의 좌우 양측을 연결하도록 구비되어 작업자의 허리에 걸림되는 허리밴드(530)를 포함한다.This portable device 500 is equipped with a battery 400 fixed to the rear, while the front is equipped with a backrest 510 attached to the back of the worker, the upper part of the backrest 510 on both sides of the front of the backrest 510, and the backrest 510. A shoulder band 520 provided to connect the lower part and hooked on the worker's shoulder, and a waist band 530 provided to connect the left and right sides of the backrest 510 at the front lower part of the backrest 510 and hooked to the worker's waist. Includes.
이때, 등받이(510)는 그 내부에 스폰지 등과 같은 쿠션이 내장되어 휴대기구(500)를 멘 작업자의 피로도를 덜어줄 수 있게 된다.At this time, the backrest 510 has a cushion, such as a sponge, built into it, which can reduce the fatigue of the worker carrying the portable device 500.
이상과 같은 본 발명에 따른 휴대용 고주파 바이브레이터의 작용을 설명한다.The operation of the portable high-frequency vibrator according to the present invention as described above will be described.
먼저, 휴대기구(500)의 등받이(510) 후면에 배터리(400)를 견고히 고정하여 장착한 후, 배터리(400)에 컨트롤러(300)의 케이블(310)을 연결하여 접속시킨 다음, 작업자가 등받이(510)의 양 어깨밴드(520)를 어깨에 걸고 허리밴드(530)를 허리에 걸어 휴대기구(500)를 등에 멘 상태로 착용한다.First, the battery 400 is firmly fixed and mounted on the back of the backrest 510 of the portable device 500, and then the cable 310 of the controller 300 is connected to the battery 400, and then the operator moves the backrest 510 to the battery 400. Both shoulder bands 520 of 510 are hung on the shoulders, and the waist band 530 is hung around the waist to wear the portable device 500 on the back.
이 상태에서 고주파 바이브레이터의 사용 시는 컨트롤러(300)의 전원을 켜 배터리(400)의 전원을 모터(120)로 인가한 상태에서 컨트롤러(300)를 조작하여 모터(120)를 작동시킨다.In this state, when using a high-frequency vibrator, the controller 300 is turned on to supply power from the battery 400 to the motor 120, and then the controller 300 is operated to operate the motor 120.
그러면, 모터(120)와 동일한 동심원으로 연결된 회전축(110)이 제자리 회전되면서 이와 같이 회전되는 제1,2 편심부(111)(112)가 바이브레이터 봉의 내주면을 타격하여 진동을 발생시킨다.Then, as the rotating shaft 110 connected to the same concentric circle as the motor 120 rotates in place, the first and second eccentric parts 111 and 112 rotated in this way strike the inner peripheral surface of the vibrator rod to generate vibration.
이때, 회전축(110)에서는 제1 편심부(111)에 의해 바이브레이터 봉(100)의 전방에서 후방보다는 큰 진동 폭이 발생되지만, 제2 편심부(112)에 의해 제1 편심부(111)에서 발생되는 큰 진동 폭이 일정 폭으로 상쇄되어 진동의 밸런스가 유지된다.At this time, in the rotation shaft 110, a larger vibration amplitude is generated at the front of the vibrator rod 100 than at the rear by the first eccentric portion 111, but at the first eccentric portion 111 by the second eccentric portion 112. The large amplitude of vibration that occurs is offset by a certain amplitude to maintain the balance of vibration.
이와 같이 제1,2 편심부(111)(112)에 의해 회전축(110)에서 밸런스가 유지된 고주파 진동이 발생되고, 모터(120)와 회전축(110)이 동일한 동심원으로 연결됨으로써 모터(120)의 부하를 최소화할 수 있으므로 모터(120)를 고속 회전시킬 수 있고, 모터(120)가 10,000∼15,000rpm으로 고속 회전됨에 따라 회전축(110)에서는 고주파 진동이 발생된다.In this way, a balanced high-frequency vibration is generated in the rotation shaft 110 by the first and second eccentric parts 111 and 112, and the motor 120 and the rotation shaft 110 are connected in the same concentric circle, so that the motor 120 Since the load can be minimized, the motor 120 can be rotated at high speed, and as the motor 120 rotates at high speed at 10,000 to 15,000 rpm, high-frequency vibration is generated in the rotation shaft 110.
이와 같이 회전축(110)에서 발생된 고주파 진동은 바이브레이터 봉(100) 전체를 통해 외부로 발산되므로 콘크리트 몰탈에서 기포를 효율적으로 제거할 수 있게 된다.In this way, the high-frequency vibration generated from the rotating shaft 110 is radiated to the outside through the entire vibrator rod 100, making it possible to efficiently remove air bubbles from the concrete mortar.
또한, 바이브레이터를 작업자가 휴대한 상태로 원하는 작업 장소로 간편히 이동할 수 있을 뿐 아니라 이동 시에도 전선에 의한 감전사고나 걸림에 의한 넘어짐 등의 안전사고는 사전에 모두 해소된다.In addition, not only can the worker easily move the vibrator to the desired work location while carrying it, but all safety accidents such as electric shock due to electric wires or falls due to tripping are eliminated in advance even during movement.
