본 고안은 수평방향으로 개폐가 되는 수평식 방화 셔터의 장치에 관한 것으로, 특히 모우터의 회전방향의 정역을 선택하여 작동시키면 이에 연동되어 셔터를 간편하게 개폐할 수 있도록 된 개폐장치에 관한 것이다.The present invention relates to a device of a horizontal fire shutter that is opened and closed in the horizontal direction, and more particularly to an opening and closing device that can be easily opened and closed the shutter in conjunction with the operation of the station of rotation of the motor selected.

수평식 방화 셔터는 통상의 수직식 셔터에 비해 널리 이용되지는 않으나, 변전소의 고압변압기 등 위험 시설물의 격납고 천정에 설치하거나, 고층건물 등의 층과 층 사이와 계단 통로에 설치하여 방화용 차단 문으로 사용되는 것으로, 이는 수직식 셔터와는 상이한 구성의 개폐장치가 요망되는 것이다.Horizontal fire shutters are not widely used in comparison with normal vertical shutters, but they are installed on the ceilings of hangars of hazardous facilities such as high-voltage transformers in substations, or between floors and stairways in high-rise buildings. It is to be used as, the opening and closing device of a different configuration than the vertical shutter is desired.

즉, 수직식 셔터와 같이 자중에 의해 셔터가 저절로 닫히지 않기 때문에 동력에 의해 셔터의 단부를 밀고 당겨서 셔터를 개폐하여야 하고, 셔터의 양측을 받쳐주는 셔터 가이드에서 작동이 원활해야 하는 것이다.That is, since the shutter is not closed by itself, such as a vertical shutter, the shutter should be opened and closed by pushing and pulling the end of the shutter by power, and the shutter guide supporting both sides of the shutter should be smoothly operated.

종래에는, 드럼에 감긴 셔터를 풀어서 셔터를 닫을때, 드럼을 회동시켜 셔터를 밀면 셔터가 밀리면서 셔터의 양측에 설치된 셔터 가이드를 따라 셔터의 양측부가 미끄러지면서 닫히게 되며, 이때, 셔터 가이드와 셔터의 양측부에서 마찰저항이 발생하여 작동시 소음이 크고, 또한 전후의 셔터끼리 겹쳐져서 셔터가이드 사이에 끼게 되어 셔터의 이동에 무리를 초래하여, 구동모우터가 타는 등의 결함이 발생하여 왔었다.Conventionally, when releasing the shutter wound on the drum to close the shutter, when the drum is rotated and the shutter is pushed, the shutter is pushed, and both sides of the shutter slide along the shutter guides installed on both sides of the shutter, thereby closing the shutter guide and the shutter. Friction resistance is generated on both sides, and noise is high during operation, and the front and rear shutters overlap each other and are sandwiched between the shutter guides, which causes excessive movement of the shutters, resulting in a burnout of the driving motor.

그리고, 소정길이 이상의 셔터는 셔터가이드에서 마찰저항이 크기 때문에 설치가 불가능한 구조적인 결함을 가진 문제점이 있는 것이었다.In addition, the shutter having a predetermined length or more has a problem with a structural defect that cannot be installed because of high frictional resistance in the shutter guide.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여, 셔터를 닫을 때와 열때, 각각 셔터의 이송방향 선단부에서 셔터를 이송시키는 힘이 작용하게 하여 셔터가이드에서 셔터가 겹쳐지지 않아 개폐동작이 원활하여 셔터의 길이에 구애를 받지 않고 고장의 원인을 최소화 시킬 수 있는 수평식 방화 셔터 개폐장치를 제공함을 목적으로 한 것이다.The present invention, in order to solve the conventional problems as described above, when closing and opening the shutter, the force to transfer the shutter at the tip of the transport direction of the shutter acts so that the shutter does not overlap in the shutter guide, smooth opening and closing operation It is an object of the present invention to provide a horizontal fire shutter opening and closing device that can minimize the cause of failure regardless of the length of the shutter.

즉, 셔터의 선단 양측을 브래킷트로 무한 궤도식의 체인에 결합하고 타단이 고정된 드럼의 양단에 축을 설치하고, 이 축을 모우터로 구동시키며, 상기 모우터축에 상호 반대로 구동되는 한쌍의 래치트 체인기어를 축설하고 이와 상기 드럼의 일측에 고정된 체인기어와 공회전하는 체인기어를 각각 체인으로 연결하고, 상기 공회전하는 체인기어의 셔터 구동용 체인기어를 일체로 결합시키고 상기 드럼의 타측으로 공회전하는 체인기어를 설치하며, 상기 드럼과 대향하는 반대측에 파이프의 양단에서 설치된 축에 고정된 각 체인기어와 상기한 각 체인기어를 무한궤도식으로 체인으로 연결하여 구성된 것이다.That is, a pair of ratchet chain gears are coupled to a chain of endless tracks with a bracket by brackets, shafts are installed at both ends of a drum fixed to the other end, and the shafts are driven by motors, and are driven oppositely to the motor shafts. And a chain gear fixed to one side of the drum and a chain gear idling at idle, respectively, by chains, a chain drive for coupling the shutter driving chain gears of the idling chain gear integrally, and idling at the other side of the drum. It is installed, and is configured by connecting each chain gear and the chain gear fixed to the shaft installed at both ends of the pipe on the opposite side facing the drum in an infinitely orbital chain.

상기와 같이 구성된 본 고안은 구동모우터를 시계방향 혹은 반시계방향으로 회전시킴에 따라서 각각 독립적으로 구동되는 래치트 체인기어가 체인기어와 체인으로 연결되어 드럼을 회동시키거나 체인의 선단을 이송시키게 되어 셔터를 개폐하는 것으로서, 각각 독립적으로 체결된 셔터가 셔터가이드에서 서로 포개지는 일이 없고, 마찰 저향을 감소시켜 개폐 동작이 원활하고, 고장이 적고 셔터의 길이를 임의대로 설정할 수 있는 것이다.According to the present invention configured as described above, the ratchet chain gears independently driven by rotating the drive motor clockwise or counterclockwise are connected to the chain gear and the chain so as to rotate the drum or transfer the front end of the chain. In order to open and close the shutter, the shutters independently connected to each other do not overlap each other in the shutter guide, and the frictional shock is reduced, so that the opening and closing operation is smooth, the failure is small, and the length of the shutter can be arbitrarily set.

미설명 부호 21은 셔터가이드이다.Reference numeral 21 is a shutter guide.

이상과 같이 구성된 본 고안의 작용, 효과를 이하에서 설명한다.The operation and effects of the present invention configured as described above will be described below.

닫혀진 셔터(1)을 열때, 제1도에서 구동모우터(4)를 시계방향으로 회동시키면, 래치트 체인기어(6)가 구동하여 체인(11)으로 연결된 체인기어(7)을 시계방향으로 회동시키고 이 체인기어(7)가 축(3)에 고정되어서 축(3)을 시계방향으로 회동시켜 이에 드럼(2)이 회동되어 셔터(1)가 드럼(2)에 감기게 되고, 셔터(1)의 우측 양단이 브래킷트(17)(17')로 체인(16)(16')에 결속되어 셔터(1)가 좌측으로 이동하면 체인(16)(16')도 이동하여 이와 연결된 체인기어(8)(8')(13)(13')도 구동하지만 체인기어(8)(13')는 종동축으로 공회전하고, 또한 체인기어(8)(13)은 축(3)과 공회전하면서 체인기어(8)와 일체로 결합된 체인기어(9)가 회전되어 체인(12)을 통하여 래치트 체인기어(6')로 동력이 전달되지만 모우터(4)의 축(5)과 래치트 체인기어(6')는 역회전시에는 공회전하게 되고, 결국 상기 체인기어(13)는 축(3')과 공회전하면서 셔터(1)가 상기 드럼(2)에 감기면서 셔터(1)는 열리게 되는 것이다.When opening the closed shutter 1, when the drive motor 4 is rotated clockwise in FIG. 1, the ratchet chain gear 6 is driven to rotate the chain gear 7 connected to the chain 11 in the clockwise direction. And the chain gear 7 is fixed to the shaft 3 to rotate the shaft 3 clockwise so that the drum 2 is rotated so that the shutter 1 is wound on the drum 2 and the shutter ( When both ends of the right side of 1) are fastened to the chains 16 and 16 'by brackets 17 and 17', and the shutter 1 moves to the left side, the chains 16 and 16 'also move and the chain connected thereto. The gears 8, 8 ', 13 and 13' are also driven, but the chain gears 8 and 13 'are idling with the driven shaft, and the chain gears 8 and 13 are idling with the shaft 3 as well. While the chain gear 9 integrally coupled with the chain gear 8 is rotated, power is transmitted to the ratchet chain gear 6 'through the chain 12, but the shaft 5 and the shaft 5 of the motor 4 are lowered. The cheat chain gear 6 'is idle at the time of reverse rotation, and eventually the sieve The popular word 13 is to idle with the shaft 3 'so that the shutter 1 is wound around the drum 2 so that the shutter 1 is opened.

반대로, 셔터(1)을 닫을때, 구동모우터(4)를 반시계 방향으로 회동시키면, 체인(12)으로 연결된 체인기어(9)가 반시계 방향으로 회동되면서 상기 체인기어(9)와 일체로 형성된 체인기어(8)도 함께 반시계 방향으로 회전되고 축(3)과는 회전이 안되면서 구동하게 되어 궤도체인(16)을 이송시켜 브래킷트(17)을 우측으로 이송시키며, 이는 셔터(1)의 선단에 고정되어 있으므로 셔터(12)을 우측으로 당기고 상기 체인(16)의 이송으로 체인기어(8')를 축(15)와 함께 회동시키고 파이프(14)와 타측의 축(15')과 체인기어(13')를 회동시키면서 체인(16')도 이동하면, 체인(16')에 고정된 브래킷트(17')를 상기 브래킷트(17)와 등속으로 운동하면서 셔터(1)가 비틀리지 않는 상태로 닫히게 된다.On the contrary, when the driving motor 4 is rotated counterclockwise when the shutter 1 is closed, the chain gear 9 connected to the chain 12 is rotated counterclockwise and integrally formed with the chain gear 9. Chain gears (8) formed by rotating also rotates counterclockwise together with the shaft (3) is not rotated to drive the track chain (16) to move the bracket 17 to the right, which is a shutter ( Since it is fixed to the tip of 1), the shutter 12 is pulled to the right, and the chain gear 8 'is rotated together with the shaft 15 by the conveyance of the chain 16, and the pipe 14 and the other shaft 15' are rotated. ) And the chain 16 'also move while rotating the chain gear 13', the shutter 17 moves at a constant speed with the bracket 17 fixed to the chain 16 '. Will close untwisted.

셔터(1)가 닫히면서 드럼(2)을 회동시키면 드럼(2)의 축(3)에 고정된 체인기어(7)가 회동하여 체인(11)과 연결된 래치트 체인기어(7)가 회동하여 체인(11)과 연결된 래치트 체인기어(6)를 구동시키지만 모우터(4)의 축(5)과는 역회전이 되어 공회전하게 되는 것이다.When the shutter 2 is closed and the drum 2 is rotated, the chain gear 7 fixed to the shaft 3 of the drum 2 rotates, and the ratchet chain gear 7 connected to the chain 11 rotates. The ratchet chain gear 6 connected to the chain 11 is driven but reversely rotates with the shaft 5 of the motor 4 to idle.

한편, 체인(16)(16')을 사용하므로 슬립현상에 의해 개폐위치가 부정확한 것 등의 부작용이 없고, 로울러(19)를 각 체인(16)(16')의 궤도 저부에 설치하여 체인(16)(16')의 처짐을 방지하고, 셔터(1) 양측 저부의 셔터(1) 가이드(21)상에 다수의 로울러(20)를 설치하여 마찰저항과 소음을 줄이고, 체인기어(15)(15')와 체인(16)(16')에 의하여 셔터(1)가 정확하고 소음이 없이 작동하게 된다.On the other hand, since the chains 16 and 16 'are used, there are no side effects such as incorrect opening and closing positions due to slippage, and the rollers 19 are installed at the bottom of the track of each of the chains 16 and 16'. (16) (16 ') to prevent sag, and a plurality of rollers (20) are installed on the shutter (1) guides 21 on both sides of the shutter (1) to reduce frictional resistance and noise, and the chain gear (15). 15 'and the chains 16 and 16' allow the shutter 1 to operate accurately and silently.

특히, 셔터(1)를 닫을 때는, 셔터(1)의 우측단부 양측에 고정된 브래킷트(17)(17')가 체인(16)(16')과 결합되어 있기 때문에, 셔터(1)의 우측단부을 당기면서 셔터(1)가 닫히게 되어 각각의 셔터(1)가 포개지는 일이 없이 닫히게 되는 것이고, 또한 셔터(1)을 열 때는 셔터(1)의 타측 단부가 결합된 드럼(2)를 구동모우터(4)로 시계방향으로 회동시키면, 셔터(1)는 드럼(2)에 감기게 되는 각각의 셔터(1)는 드럼(2) 쪽으로 끌리면서 열리게 되어 각각의 셔터(1)가 포개지는 일이 없어서 셔터(1)의 작동중지로 인하여 구동모우터(4)가 타는 일이 없는 것이다.In particular, when closing the shutter 1, since the brackets 17 and 17 'fixed to both sides of the right end of the shutter 1 are engaged with the chains 16 and 16', The shutter 1 is closed while pulling the right end, so that the shutters 1 are closed without overlapping each other. Also, when the shutter 1 is opened, the drum 2 having the other end of the shutter 1 coupled thereto is opened. When rotated clockwise by the drive motor 4, the shutter 1 is opened to the drum 2 while each shutter 1 is wound toward the drum 2 so that each shutter 1 overlaps. The driving motor 4 does not burn due to the operation of the shutter 1 being not lost.

또한, 개폐되는 셔터(1)의 길이는 셔터(1)와 체인(16)(16')의 길이를 설정하여 임의대로 설정할 수 있어서 설치장소 및 크기에 구애됨이 없이 특징이 있는 것이다.In addition, the length of the shutter 1 to be opened and closed can be set arbitrarily by setting the length of the shutter 1 and the chains 16 and 16 ', which is characteristic regardless of the installation place and size.

한편, 셔터(1)의 개폐시 셔터(1)가 정확한 위치에서 정지하도록 하기 위한 수단은 셔터(1)의 길이와 드럼(2)의 직경, 및 셔터(1)가 드럼(2)에 감기는 수에 따라 증가하는 권회직경의 변화 등을 감안하는 모우터(4) 회전수를 정확하게 정하고, 그 회전수 만큼 회전하도록 리미트 스위치를 설치하여 사용하면 되고 또한, 셔터(1)의 선단에 의해 작동되는 스톱 스위치를 상기한 앵글(18)표면에 별도로 설치할 수 있어서 정확하게 셔터(1)를 개폐할 수 있음은 물론이다.On the other hand, means for causing the shutter 1 to stop at the correct position when opening and closing the shutter 1 include the length of the shutter 1 and the diameter of the drum 2 and the shutter 1 being wound on the drum 2. The number of rotations of the motor 4 may be accurately determined in consideration of the change in the winding diameter that increases with the number, and the limit switch may be installed and used to rotate by the number of rotations.
