The first main gear winds the chains on a driving sheave formed on the first main gear. The chain box contains wound chains divided by separators for preventing tangle of the chains. The first small gear is engaged with the first main gear for receiving power from the main gear. The second small gear is engaged with the first small gear for transmitting the power from the first motor for balancing the power distribution. The second main gear is powered by the second motor independently at the same time interactively powered by the first motor.

Description

동기식 체인 리프트 장치{chain lift apparatus which is compatibly operated} Synchronous chain lift apparatus {chain lift apparatus which is compatibly operated}

도 1 은 본 발명에 따른 장치에 대한 개략 구성도1 is a schematic configuration diagram of an apparatus according to the present invention;

도 2 는 주요 구성에 대한 상세도2 is a detailed view of the main configuration

도 3 은 도 1 의 우측 요부 단면도3 is a right main cross-sectional view of FIG.

본 발명은 조명 장치를 들어 올리고 내릴 경우에 사용되는 리프트 장치에 관한 것이다The present invention relates to a lift device used when lifting and lowering a lighting device.

예를 들어, 실내 체육관, 각종 무대 등에는 조명장치가 설치되는데 이들을 필요에 상하, 좌우로 이동시켜야 한다For example, lighting devices are installed in indoor gymnasiums and various stages, and they must be moved up and down and left and right as needed.

상하로 이송시키는 종래의 장치 경우, 좌우 와이어에 의한 감고 푸는 작동으로 조명기구를 승강시키므로 인해, 좌우의 와이어 감는 속도차가 생기므로, 수평이 되지 아니하는 문제가 발생한다In the conventional apparatus for transporting up and down, the lighting device is lifted by the winding and unwinding operation by the left and right wires, and thus the left and right wire winding speed difference occurs, which causes the problem of not being horizontal.

더욱 상세히 말하면, 와이어가 와이어 드럼에 감길때, 와이어가 이미 감겨진 와이어 위에 중첩되게 감길때, 드럼의 감는 직경이 달라지므로 감기는 속도 차이가 생긴다. 그리고 좌우 양쪽에서 와이어를 감으므로, 좌,우에서 감는 작동이 완전 동일하게 이루어지지 않는 한, 양쪽 중 어느 한쪽이 필연적으로 더 많이 또는 적게 감기게 된다More specifically, when the wire is wound on the wire drum, when the wire is wound over the already wound wire, the winding diameter of the drum is different and thus the winding speed difference occurs. And because the wires are wound on both left and right sides, one or both sides will inevitably have more or less winding, unless the winding operation is done exactly the same on the left and right sides.

그러면 좌,우의 들어 올리는 높이 차가 발생하므로, 좌우의 어느 한쪽이 기울어지게 된다. As a result, a difference in lifting height of the left and right sides occurs, and thus one of the left and right sides is inclined.

본 발명은 상기한 점을 감안하여 발명한 것으로, 조명기구를 장착한 구조물을 좌,우 기울어짐이 전혀 발생하지 않고 정확히 수평을 유지하여 승강이 가능한 장치를 제공함에 본 발명의 목적이 있다.

상기한 특징 외의 다른 특징 및 구성에 대하여, 이하, 첨부 도면에 의거 추가로 상술한다Other features and configurations other than those described above will be further described below based on the accompanying drawings.

도 1 은 본 발명에 따른 리프트 시스템의 전체 구성을 보여 주기 위한 도면이다.1 is a view for showing the overall configuration of a lift system according to the present invention.

도시한 바와 같이, 본 발명에서는 트랙체(1)를 체인(2)으로 들어 올리 수 있 게 구성된다As shown, in the present invention, the track body 1 is configured to be lifted by the chain 2.

트랙체(1)는 여러개의 행거(3)로 연결되고, 행거(3)에는 체인(2)이 연결된다. 체인(2)은 모터(5)에 의해 감겨진다. 모터(5)가 작동되면 메인기어(6)가 회전한다. 메인기어(6)에는 구동시브(7)가 형성되어 있어서, 이곳에서 체인(2)을 걸어 회전하면 체인(2)이 감겨진다The track body 1 is connected by several hangers 3, and the chain 2 is connected to the hanger 3. The chain 2 is wound by the motor 5. When the motor 5 is operated, the main gear 6 rotates. The drive sheave 7 is formed in the main gear 6, and the chain 2 is wound when the chain 2 is walked and rotated here.

감겨진 체인(2)은 체인박스(9)에 내장된다. 체인박스(9) 내부에는 격벽(10)이 형성되어 있어서, 다른 체인과 얽히지 않는다. 메인기어(6)에서의 전동력은 전동기어(12)에 전달하고, 이 전동기어(12)는 피동기어(13)에 전달되어 다른 체인 즉 제2 체인(14)을 감는다. 메인기어(6)의 상부에는 소기어(15)가 맞물려 있고 소기어(15)는 제2소기어(16)와 물린다The wound chain 2 is embedded in the chain box 9. The partition wall 10 is formed inside the chain box 9, so that it is not entangled with other chains. The electric force in the main gear 6 is transmitted to the electric gear 12, which is transmitted to the driven gear 13 to wind another chain, that is, the second chain 14. The small gear 15 is engaged with the upper part of the main gear 6, and the small gear 15 is bitten by the second small gear 16.

제2소기어(16)는 제2메인기어(17)와 기어로 연결된다. 제2기어(17)는, 별도의 제2모터(18)에 의해 구동된다. 즉, 모터(5)와 제2모터(18)는 각각 독립적으로 구동되는 것으로, 그 각각의 구동력이 메인기어(6) 및 제2메인기어(17)에 각각 전동된다. 그러나 소기어(15)와 제2소기어(16)에 의해 맞물려 있는 관계로 상호 힘이 작용된다The second small gear 16 is connected to the second main gear 17 by a gear. The second gear 17 is driven by another second motor 18. That is, the motor 5 and the second motor 18 are driven independently of each other, and the respective driving forces are transmitted to the main gear 6 and the second main gear 17, respectively. However, mutual force is acted on by the engagement between the small gear 15 and the second small gear 16.

예를 들어, 한쪽 모터가 작동하지 않거나 힘이 약하더라도 양쪽 모두의 기어에 힘이 전달되므로 전체적으로 작동이 멈추거나, 좌우 불균일하게 힘이 작용하여 체인이 감기는 것을 방지한다. 이와 같이 좌우 균일하게 힘이 작용하면 트랙체(1)의 승강을 수평으로 유지하면서 승강 시킬 수 있는 효과가 있다For example, even if one motor is not working or the power is weak, the force is transmitted to both gears, so that the operation is stopped as a whole or the force is applied unevenly to the left and right to prevent the chain from winding. In this way, when the force acts uniformly on the left and right side, there is an effect that the lifting and lowering of the track body 1 can be carried out horizontally.

또한 소기어(15)와 제2소기어(16)의 구성과 작동으로 인해 2 개의 모터가 각 각 작동하여도 좌,우에서 동시에 감가는 것이 가능하다In addition, due to the configuration and operation of the small gear 15 and the second small gear 16, it is possible to simultaneously reduce the left and right sides even if the two motors are operated.

도 1 에서 미설명 부호 19와 20 은 서포터와 체인시브이다In FIG. 1, reference numerals 19 and 20 denote supporters and chain sheaves.

행거(3)에 매달려 있는 트랙체(1)에는 트롤리바(22)가 크립(23)에 의해 고정 설치되어 있어서, 이 트롤리바(22) 레일을 따라 무빙카(24)가 좌우 이동 가능하다. 무빙카(24)에는 조명기구(25)가 설치된다The trolley bar 22 is fixed to the track body 1 hanging on the hanger 3 by the creep 23, and the moving car 24 can move left and right along this trolley bar 22 rail. The lighting device 25 is installed in the moving car 24.

본 출원인은, 트랙을 따라 이동하는 조명시스탬에 대한 것으로, "트랙이동식 조명 시스템" 이라는 명칭으로 특허 등록 제 555743 호로 이미 권리를 획득한 바 있다Applicant has already obtained rights under patent registration No. 555743 for the lighting system moving along the track, under the name "trackable lighting system".

도 3 은 도 1 을 우측면에서 본 요부 단면도이다3 is a sectional view of the main parts of FIG. 1 seen from the right side.

도시한 바와 같이, 체인박스(9) 상부로는 전,후방으로 프레임(27)이 조립되며 프레임(27)의 상부는 볼트(28)로 조립된다As shown in the drawing, the upper part of the chain box 9 is assembled with the frame 27 in the front and rear, and the upper part of the frame 27 is assembled with the bolts 28.

도 1 의 후방, 즉, 도 3 에서 우측에는 모터(18)가 설치되고, 반대쪽 전방에는 콘트롤 박스(29)가 설치된다. 콘트롤박스(29)는 체인의 작동을 제어하는 기능을 하기 위해 설치되는 것이다. A motor 18 is installed at the rear of FIG. 1, that is, at the right in FIG. 3, and a control box 29 is installed at the opposite front. The control box 29 is installed to function to control the operation of the chain.

이상과 같은 본 발명에 의하면, 체인에 의해 감고 풀리는 작동이므로 작동이 정확하다. According to the present invention as described above, the operation is accurate because the operation is wound and unrolled by the chain.

또한 모터가 2 개 작동함으로 인해 힘이 강력하고, 또한 모터 한쪽의 힘이 약하거나 작동이 멈추어도 다른 반대편 기어들에게 힘이 미치므로, 승,하강 작동에 지장을 주기 않고 좌우의 승,하강 속도가 균일하게 이루어진다.In addition, the power of the two motors is strong, and even if the power of one side of the motor is weak or the operation stops, the other gears exert a force on the other side. Is made uniform.

또한, 본 발명에 의하면, 트랙체(1)가 예시한 것보다 더 길 경우, 기어의 조합 수를 더 늘리면 되므로 수평 유지에 지장이 없다In addition, according to the present invention, when the track body 1 is longer than illustrated, the number of gear combinations can be increased further, so there is no problem in maintaining the level.

예를 들어, 트랙체(1)의 가로 길이는 매우 긴데, 이를 체인을 통하여 감아 올리는 체인의 갯수가 적으면, 예를 들어 도면과 같이 4 곳에서만 들어올리면, 트랙체(1)가 처지게 된다. 따라서 모터와 메인기어와 전동기어 및 피동기어 조합체를, 좌우에 필요에 따라 더 기어 연결하여 설치 가능하다.For example, if the length of the track body 1 is very long, and the number of chains that are wound up through the chain is small, for example, if it is lifted only at four places as shown in the drawing, the track body 1 sags. . Therefore, the combination of the motor, the main gear, the electric gear and the driven gear can be installed by connecting the gears more to the left and right as needed.

반대로 설비 규모가 작을 경우엔, 모터와 기어의 수량을 좌,우 1세트씩 줄이면 되므로 설비 규모에 따라 자유롭게 축소 및 확장이 가능하다. On the contrary, if the equipment size is small, the number of motors and gears can be reduced by one set of left and right, so it can be freely reduced and expanded according to the equipment size.
