캔버스 도어 안전 개폐장치{Safe open and close device of canvasdoor}Safe door and close device of canvasdoor

본 발명은 캔버스 도어 안전 개폐장치를 제공하기 위한 것으로써, 보다 상세히는 전동기의 양쪽 드럼에 권회된 와이어로 견인되는 도어의 업다운 동작때 도어 중심의 흔들림을 최대한 방지하여 수직으로의 업다운동작이 원활히 되고, 하나의 와이어가 절단되더라도 하부트러스의 휨 현상없이 곧바로 유지 보수작업을 행할 수 있어 작업이 신속 간편하고 유지 보수비용이 저렴하게 소요되는 캔버스 도어 안전 개폐장치에 관한 것이다. The present invention is to provide a canvas door safety opening and closing device, in more detail in the up-down operation of the door towed by the wire wound on both drums of the electric motor to prevent the shaking of the center of the door as much as possible to smooth the vertical up and down operation In addition, even if one wire is cut, the maintenance work can be performed immediately without bending the lower truss, and thus, a quick and simple operation and low maintenance cost of the canvas door safety opening and closing device.

일반적으로 캔버스 도어(Canvas Door)는 철구조물로 만들어지는 대형문의 일종으로서 빅도어 또는 그랜드도어라고도 불리며, 선박의 블럭 제작과 같은 대형 제품의 출입을 필요로 하는 조선소나 중공업의 대형 공장, 항공기 격납고, 대형의 물류 보관창고 등지에 널리 설치되어 사용되고 있다.In general, a canvas door is a large door made of steel structure, also called a big door or a grand door, and a large factory, an aircraft hangar of a shipyard or a heavy industry that requires access to a large product such as a ship block. It is widely installed and used in large logistics warehouses.

상기 캔버스 도어는 매쉬나 천으로 된 스크린이 일면에 부착되는 도어본체, 도어본체의 상하 업다운을 안내하는 양쪽 안내레일, 도어본체를 와이어로 매달아 업다운시키는 와이어드럼이 기어드모터의 양쪽 구동축에 각각 설치되는 동력구동부, 동력구동부의 동작을 제어하는 콘트롤러 등의 구성요소가 구비되어 만들어진다. The canvas door has a door body having a mesh or cloth screen attached to one side thereof, both guide rails for guiding the up and down of the door body, and a wire drum for hanging up and down the door body with wires are installed on both drive shafts of the geared motor. Components such as a power drive unit, a controller for controlling the operation of the power drive unit is provided.

도 1 은 종래의 캔버스 도어 개폐장치를 도시한 정면도이고, 도 2 는 종래 캔버스 도어 개폐장치의 동력구동부를 확대하여 보인 정면도 이다. 1 is a front view showing a conventional canvas door opening and closing device, Figure 2 is an enlarged front view of the power drive of the conventional canvas door opening and closing device.

이에 도시된 바와 같이 종래의 캔버스 도어 개폐장치는 건물 출입구의 양쪽에 설치된 안내레일(13)을 따라 하부트러스(12)가 상부트러스(11)를 향해 업다운되는 도어본체(10); 상부트러스(11) 중앙에 설치되며, 도어본체(10) 견인용 와이어(24)가 감겨있는 와이어드럼(23a)(23b)이 기어드모터(21)의 양쪽 구동축(22)에 각각 설치된 동력구동부(20); 도어본체(10)의 양단에 결착되는 와이어드럼(23a)(23b)의 와이어(24)를 지그재그로 안내시키기 위해 상부트러스(11)와 하부트러스(12)에 설치되는 상하측 안내풀리(30a)(30b); 로 구성되어 있다. As shown therein, the conventional canvas door opening and closing device includes a door main body 10 in which the lower truss 12 is moved up and down toward the upper truss 11 along guide rails 13 installed at both sides of the building entrance and exit; It is installed in the center of the upper truss 11, the power drum (23a, 23b) is wound on the drive shaft 22 of the geared motor 21, the wire drum (23a, 23b) is wound around the door body (10) 20); Upper and lower guide pulleys 30a installed on the upper truss 11 and the lower truss 12 for zigzag guiding the wires 24 of the wire drums 23a and 23b which are attached to both ends of the door body 10. 30b; Consists of

그리고, 상기 캔버스 도어의 도어본체(10)는 일반적으로 약 15~20톤에 달하는 중량을 갖는 무거운 대형문으로 만들어져 설치되며, 이러한 중량의 도어본체(10)를 구동시키는 종래의 캔버스 도어 개폐장치는 도어본체(10)의 하부트러스(12) 양단에 각각 한 가닥의 와이어(24)만을 결착시켜 동작시키고 있다. And, the door body 10 of the canvas door is generally made of a heavy large door having a weight of about 15 to 20 tons and installed, the conventional canvas door opening and closing device for driving the door body 10 of this weight is Only one wire 24 is attached to both ends of the lower truss 12 of the door body 10 to operate.

그런데, 양쪽 와이어드럼(23a)(23b)에 각각 한 가닥씩 감겨있는 와이어(24)로 도어본체(10)의 하부트러스(12) 양단을 각각 견인하여 도어본체(10)를 업다운시키는 도중에 어느 한쪽의 와이어(24)가 노후되어 절단되기라도 하면 도어본체(10)는 무거운 하중이 한쪽으로 쏠리면서 낙하되어 대형사고를 유발하게 된다. However, either side of the lower truss 12 of the door body 10 is pulled by the wires 24 wound on each of the wire drums 23a and 23b, respectively, so that the door body 10 is pulled up or down. If the wire 24 is aged and cut, the door body 10 is dropped while the heavy load is pulled to one side, causing a large accident.

그러므로 종래에는 도어본체(10)의 양쪽에 비상시 도어를 잡아주기 위한 록킹장치(도면에 미도시)를 설치하여 어느 한 쪽의 와이어(24)가 끊어져 도어본체(10)의 무게 중심이 어느 한쪽으로 쏠릴 경우 록킹장치를 구동시켜서 도어본체(10)를 잡아주도록 하였는데, 이는 별도의 록킹장치를 구비하여야 되므로 시공비가 많이 드는 폐단이 있다. Therefore, in the related art, a locking device (not shown in the drawing) is installed on both sides of the door body 10 to hold the door in an emergency so that either wire 24 is broken so that the center of gravity of the door body 10 is moved to either side. When the lock is driven to drive the locking device to hold the door body 10, which must be provided with a separate locking device, there is a closed end costing a lot of construction costs.

그리고, 상기와 같이 한쪽 와이어(24)가 절단되어 도어본체(10)가 한쪽으로 쏠리게 되면 도어본체(10)의 파손뿐만 아니라 하부트러스(12)가 "V"자로 휘는 현상이 발생되므로 도어 교체에 따른 보수작업이 매우 커지게 되고, 이에 따른 작업시간과 인력 소모가 많아 유지보수비가 과다하게 소요되는 문제점이 있다.And, as described above, if one of the wires 24 is cut and the door body 10 is pulled to one side, the door truss 12 may be bent as well as the door truss 10. There is a problem that the maintenance work is very large, and accordingly there is a lot of work time and manpower consumption, excessive maintenance costs.

이에 본 발명은 상기한 종래의 문제점을 해결하기 위해 개발된 것으로서, 본 발명은 도어본체가 수직으로의 업다운동작이 원활하게 되면서도 어느 한쪽 와이어가 절단되더라도 도어본체의 낙하됨을 방지하여 안정성을 도모하고 도어본체 및 하부트러스의 휩 변형 등이 발생되지 않는 캔버스 도어 안전 개폐장치를 제공하는데 그 목적이 있다. Accordingly, the present invention has been developed to solve the above-described problems, the present invention is to improve the stability by preventing the door body from falling even if any wire is cut while the door body is vertically up and down smoothly. An object of the present invention is to provide a canvas door safety opening and closing device that does not cause whip deformation of the main body and the lower truss.

또한 본 발명은 어느 한쪽의 와이어가 끊어지더라도 도어본체의 설치상태가 그대로 유지됨에 따라 끊어진 와이어만의 보수작업을 행하면 되므로 보수작업이 신속 간편하고, 유지 보수비용이 저렴한 캔버스 도어 안전 개폐장치를 제공하는데 그 목적이 있다. In addition, the present invention provides a canvas door safety opening and closing device is easy and quick maintenance, low maintenance costs, because only one wire is broken, as the installation state of the door body is maintained as it is, even if any one wire is broken. Its purpose is to.

상기와 같은 본 발명의 목적은, 건물 출입구의 상부트러스 하부 양쪽에 설치된 안내레일을 따라 업다운되는 도어본체; 상부트러스 위에 설치되며, 기어드모터의 양쪽 구동축에 와이어드럼이 각각 끼워진 동력구동부; 와이어드럼의 와이어를 상부트러스와 하부트러스에 지그재그로 안내시키는 상하측 안내풀리; 로 캔버스 도어 개폐장치를 구성하되, 양쪽 구동축의 와이어드럼에는 2가닥의 와이어를 각각 양쪽 외측단에서 중앙을 향해 감기도록 대향으로 권취하여 도어본체의 업다운시 2가닥의 와이어가 서로 간섭되지 않도록 구성함으로써 달성되는 것이다.An object of the present invention as described above, the door body up and down along the guide rail installed on both sides of the upper truss of the building entrance; A power drive unit installed on the upper truss and having wire drums respectively fitted to both drive shafts of the geared motor; Upper and lower guide pulley for zigzag guiding the wire of the wire drum to the upper truss and the lower truss; By constructing a canvas door opening and closing device, the wire drums of both drive shafts are wound in opposite directions so that two wires are respectively wound from the outer end to the center at both ends so that the two wires do not interfere with each other when the door body is up and down.

이에 도시된 본 발명의 구성 중, 건물 출입구의 양쪽에 설치된 안내레 일(130)을 따라 하부트러스(120)가 상부트러스(110)를 향해 업다운되는 도어본체(100); 상부트러스(110) 중앙에 설치되며, 기어드모터(210)의 양쪽 구동축(220)에 각각 와이어드럼(230a)(230b)이 설치된 동력구동부(200); 상부트러스(110)와 하부트러스(120)에 설치되며, 와이어드럼(230a)(230b)의 와이어를 하부트러스(120)에 지그재그로 안내하는 상하측 안내풀리(300a)(300b); 로 캔버스 도어 개폐장치를 구성하는 것은 종래와 같다고 할 수 있다. In the configuration of the present invention, the lower body truss 120 along the guide rails 130 provided on both sides of the building entrance and exit toward the upper truss 110 (100); A power drive unit 200 installed at the center of the upper truss 110 and having wire drums 230a and 230b respectively installed at both drive shafts 220 of the geared motor 210; Upper and lower guide pulleys 300a and 300b installed on the upper truss 110 and the lower truss 120 and zigzag the wires of the wire drums 230a and 230b to the lower truss 120; It can be said that what constitutes a furnace canvas door opening and closing apparatus is the same as the conventional one.

본 발명의 특징은 양쪽 구동축(220)에 설치된 각 와이어드럼(230a)(230b)에는 양쪽 외측단에서 중앙을 향해 2가닥의 와이어(240)(241)를 각각 대향으로 권취하되 도어본체(100) 상승시에는 대향 권취된 2가닥의 와이어(240)(241)가 일정 간격(ℓ)만큼 좁혀질 때까지만 권취되게 하고, 도어본체(100) 하강시에는 일정 간격(ℓ)만큼 좁혀져 있던 2가닥의 와이어(240)(241)가 점차 간격이 멀어지면서 풀리도록 하여 상기 2가닥의 와이어(240)(241)가 하나의 와이어드럼에서 동시에 감기거나 풀릴 때 서로 간섭받지 않도록 한 것을 특징으로 한다. The present invention is characterized in that each of the wire drums (230a, 230b) installed on both drive shafts 220 are wound in two wires (240, 241) facing each other toward the center at both ends of the door body 100 At the time of ascension, the two wound wires 240 and 241 are wound only until they are narrowed by a predetermined interval (l), and when the door body 100 is lowered, the two strands of the wire are narrowed by a predetermined interval (l). The 240 and 241 are gradually spaced apart so that the two strands of wire 240 and 241 are wound or unwound at the same time in one wire drum.

여기서, 상기 상하측 안내풀리(300a)(300b)는 2가닥의 와이어(240)(241)가 서로 이격된 상태로 안내되도록 복수의 안내부(310)(311)를 일렬로 구비하는 것이 바람직하다.Here, the upper and lower guide pulleys (300a, 300b) is preferably provided with a plurality of guides 310, 311 in a row so that the two wires 240, 241 are guided in a state spaced apart from each other. .

이와 같이 형성된 본 발명은 동력구동부(200)의 기어드모터(210) 양쪽에 대향되어 돌출된 구동축(220)에 각각 와이어드럼(230a)(230b)이 설치되어 있으므로 구동축(220)의 정역회전되는 방향을 따라 양쪽 와이어드럼(230a)(230b)은 함께 정역회전 되면서 와이어(240)(241)를 감거나 풀어주게 된다. In the present invention formed as described above, since the wire drums 230a and 230b are respectively installed on the drive shafts 220 protruding from both sides of the geared motor 210 of the power driving unit 200, the direction in which the drive shafts 220 are reversely rotated. Both wire drums 230a and 230b are wound along and reversed together while winding or releasing the wires 240 and 241.

그리고 양쪽 와이어드럼(230a)(230b)이 와이어(240)(241)를 감으면 상하측 안내레일(130)에 의해 안내되는 와이어(240)(241)가 도어본체(100)를 끌어 올림에 따라 도어본체(100)가 양쪽의 안내레일(130)을 따라 상부트러스(110)를 향하여 수직으로 상승되고, 반대로 양쪽 와이어드럼(230a)(230b)이 와이어(240)(241)를 풀어주면 도어본체(100)가 양쪽 안내레일(130)을 따라 하부로 수직 하강되는 것으로서, 이는 종래의 캔버스 도어 개폐장치와 같다고 할 수 있다. When both wire drums 230a and 230b are wound around the wires 240 and 241, the wires 240 and 241 guided by the upper and lower guide rails 130 pull up the door body 100. The door body 100 is vertically elevated toward the upper truss 110 along the guide rails 130 on both sides, and on the contrary, when both wire drums 230a and 230b release the wires 240 and 241, the door body As 100 is vertically lowered along both guide rails 130, this can be said to be the same as the conventional canvas door opening and closing device.

여기서, 본 발명은 기어드모터(210)의 양쪽 구동축(220)에 설치된 각 와이어드럼(230a)(230b) 마다 2가닥의 와이어(240)(241)를 서로 간섭을 받지 않으면서 감기거나 풀리도록 권취하여 도어본체(100)의 상승 및 하강시 안정성을 부여하고, 어느 한 가닥의 와이어가 절단되더라도 유지 보수작업을 신속 간편하게 행할 수 있도록 함을 특징으로 한 것이다.Here, the present invention is wound around each wire drum (230a, 230b) installed on both drive shafts 220 of the geared motor 210, the two wires 240, 241 wound or unwound without interference with each other It is characterized in that it gives stability when the door body 100 is raised and lowered, and it is possible to quickly and easily perform maintenance work even if any one wire is cut.

즉, 본 발명은 도어본체(100)를 상승시키기 위해 기어드모터(210)의 구동축(220)에 설치된 와이어드럼(230a)(230b)을 일방향으로 회전시키면 각 와이어드럼(230a)(230b)에 권취된 2가닥의 와이어(240)(241)는 양쪽 외측단에서 중앙을 향해 감기면서 도어본체(100)를 상승시키게 된다. That is, according to the present invention, when the wire drums 230a and 230b installed in the drive shaft 220 of the geared motor 210 are rotated in one direction to lift the door body 100, the wire windings are wound around the wire drums 230a and 230b. The two-wire wire 240, 241 is wound up toward the center at both outer ends to raise the door body 100.

이때, 도어본체(100)를 완전 상승시키더라도 대향 권취된 2가닥의 와이어(240)(241)는 일정 간격(ℓ)으로 좁혀질 때까지만 권취될 뿐이므로 각 와이어드럼(230a)(230b)의 중앙 부위에 별도의 와이어 간섭방지용 구획벽을 구비하지 않더라도 서로 간섭될 우려가 없이 감길 수 있다. At this time, even if the door body 100 is fully raised, the two strands of wires 240 and 241 wound oppositely are wound only until they are narrowed at a predetermined interval (L), so that each wire drum (230a) (230b) Even if the central portion is not provided with a separate wire barrier to prevent interference can be wound without interference.

그리고, 상기와 같이 상승된 도어본체(100)를 다시 하강시키고자 와이어드 럼(230a)(230b)을 반대방향으로 회전시키면 일정 간격(ℓ)만큼 좁혀져 있던 2가닥의 와이어(240)(241)는 점차 간격이 멀어지면서 상하측 안내풀리(300a)(300b)로 안내되어 풀림에 따라 도어본체(100)는 하강을 하게 된다. In addition, when the wire drums 230a and 230b are rotated in the opposite direction to lower the raised door body 100 again, the two wires 240 and 241 that are narrowed by a predetermined interval (l) are The door body 100 is lowered as the gap is gradually separated and guided to the upper and lower guide pulleys 300a and 300b.

이와 같이 각 와이어드럼(230a)(230b)에 대향으로 감겨있던 2가닥의 와이어(240)(241)는 그 간격이 점차 멀어지면서 풀림에 따라 서로 간섭을 전연 받지 않고 풀리게 되며, 이러한 2가닥의 와이어(240)(241)는 복수의 안내부(310)(311)가 일렬로 구비된 안내풀리(300a)(300b)에 안정적으로 안내되므로 도어본체(100)의 상승 및 하강이 안정적으로 행하여 질 수 있다.As described above, the two wires 240 and 241 wound around each of the wire drums 230a and 230b are unwound as the gap is gradually released, without being interfered with each other. The 240 and 241 are stably guided to the guide pulleys 300a and 300b in which the plurality of guide parts 310 and 311 are provided in a row, so that the up and down of the door body 100 can be stably performed. have.

도 6 은 본 발명의 다른 실시예로서, 상기 2가닥의 와이어(240)(241)가 감기거나 풀릴 때 서로 간섭받지 않도록 하는 것을 반대로 구성한 것이다. FIG. 6 is another embodiment of the present invention, in which the two wires 240 and 241 are configured so as not to interfere with each other when they are wound or unwound.

즉, 여기서는 양쪽 구동축(220)의 각 와이어드럼(230a)(230b)에 2가닥의 와이어(240)(241)를 대향으로 간섭받지 않도록 설치할 때 양쪽 구동축(220)의 각 와이어드럼(230a)(230b) 중앙에 2가닥의 와이어(240)(241)의 끝단을 일정 간격(ℓ) 떨어지게 클램프한 상태에서 각 와이어드럼(230a)(230b)의 양쪽 외측단을 향해 점차 벌어지도록 대향으로 권취한 것이다. That is, in this case, when installing two wires 240 and 241 on the respective wire drums 230a and 230b of both drive shafts 220 so as not to interfere with each other, the wire drums 230a and the wires of both drive shafts 220 ( 230b) The two ends of the wires 240 and 241 in the center are clamped at a predetermined distance (l) apart in a state in which they are wound up to be gradually opened toward both outer ends of the wire drums 230a and 230b. .

이와 같이 하면 도어본체(100)를 상승시키기 위해 와이어드럼(230a)(230b)을 일방향으로 회전시켜서 와이어(240)(241)를 감을 때 대향 권취된 2가닥 와이어(240)(241) 간의 간격이 점차 멀어지면서 와이어드럼(230a)(230b)에 감기므로 2가닥의 와이어(240)(241)가 하나의 와이어드럼에 구획벽 없이 함께 감겨서 동작되더라도 서로 간섭을 받지않게 된다.In this case, the wire drums 230a and 230b are rotated in one direction to raise the door body 100 so that the gap between the two stranded wires 240 and 241 wound up is wound when the wires 240 and 241 are wound. As it is gradually moved away and wound on the wire drums 230a and 230b, even if two wires 240 and 241 are wound together without a partition wall on one wire drum, they do not interfere with each other.

그리고, 도어본체(100)를 하강시키고자 와이어드럼(230a)(230b)을 반대방향으로 회전시키면 2가닥의 와이어(240)(241)는 와이어드럼(230a)(230b)의 중앙을 향해 점차 간격이 좁혀지면서 풀리므로 도어본체(100)는 하강하게 된다.Then, when the wire drums 230a and 230b are rotated in the opposite direction to lower the door body 100, the two wires 240 and 241 are gradually spaced toward the center of the wire drums 230a and 230b. The door body 100 is lowered since it is narrowed and released.

이때 2가닥의 와이어(240)(241)는 끝단이 와이어드럼(230a)(230b)의 중앙부위에 일정 간격(ℓ) 이격된 상태로 클램프되어 있으므로 도어본체(100)의 하강을 위해 2가닥의 와이어(240)(241)를 풀어줄 때 서로 간섭받지 않고 풀리게 되는 것으로서, 도어본체(100)의 업다운 동작이 매우 안정적으로 이루어 질 수 있다. At this time, since two ends of the wires 240 and 241 are clamped at an end spaced apart by a predetermined distance (l) from the ends of the wire drums 230a and 230b, the two strands of wires 240 and 241 are lowered to lower the door body 100. When the wires 240 and 241 are released without being interfered with each other, the up-down operation of the door body 100 may be made very stable.

이러한 본 발명은, 각각의 와이어드럼(230a)(230b) 마다 2가닥의 와이어(240)(241)를 대향으로 감아서 서로 간섭받지 않는 상태에서 양호하게 감기거나 풀리는 것이므로 캔버스 도어의 업다운 동작이 보다 안정적으로 될 수 있다. In the present invention, each of the wire drums 230a and 230b has two wires 240 and 241 wound in opposite directions so that they can be wound or unwound in good condition without being interfered with each other. Can be stable.

그리고, 하나의 와이어드럼(230a)(230b) 마다 2가닥의 와이어(240)(241)가 감겨 있는 것이므로 도어본체(100)를 수직으로 상승 또는 하강시키는 도중 어느 하나의 와이어가 노후 등으로 인해 절단되더라도 그 자리에서 어떠한 변화가 발생하지 않아 보수를 용이하게 할 수 있는 장점이 있다. Since one wire drum 230a, 230b is wound with two wires 240 and 241, any one wire is cut due to deterioration or the like while the door body 100 is vertically raised or lowered. Even if there is no change on the spot there is an advantage that can facilitate the repair.

즉, 본 발명은 와이어드럼(230a)(230b)마다 감겨있는 2가닥의 와이어(240)(241) 중 어느 하나가 절단되더라도 나머지 1가닥의 끊어지지 않은 와이어가 도어본체(100)의 견인 상태를 그대로 양호하게 유지하여 준다. 그러므로 종래처럼 한쪽 와이어가 절단되기만 하면 발생되는 도어본체(100)의 파손이나 하부트러스(120)의 휨 변형 등의 변화가 없어 보수가 용이한 것이다. That is, in the present invention, even if any one of the two wires 240 and 241 wound around each of the wire drums 230a and 230b is cut, the remaining one strand of the wire does not change the traction state of the door body 100. Keep it good as it is. Therefore, there is no change in the breakage of the door body 100 or the bending deformation of the lower truss 120, which is generated when only one wire is cut as in the related art.

그리고, 종래처럼 도어본체(100)의 와이어가 끊어진 부위를 잡아주기 위한 별도의 록킹장치를 구비할 필요가 없어 캔버스 도어를 설치하는데 따른 시공비가 종래에 비해 저렴하다. In addition, since it is not necessary to provide a separate locking device for holding a broken portion of the wire of the door body 100 as in the prior art, the construction cost for installing the canvas door is cheaper than in the related art.

또한, 도어본체(100)의 설치상태가 끊어지지 않은 1가닥의 와이어에 의해 그대로 유지된 상태에서 곧바로 끊어진 와이어만의 보수작업을 행하면 되므로 애프터서비스(A/S)를 하더라도 보수작업이 매우 간편하면서도 신속하고, 유지 보수비용이 저렴한 것으로서, 캔버스 도어 동작에 따른 안정성과 보수 차원에서 매우 유용한 것이다.In addition, since the maintenance work of the broken wire is carried out only in the state in which the door body 100 is kept intact by one unbroken wire, the maintenance work is very easy even after the after-sales service (A / S). It is quick and inexpensive to maintain, and it is very useful in terms of stability and maintenance of canvas door operation.
