대형 건축구조물용 도어의 추락방지장치{Fall prevention device of door for reinforcement structure}Fall prevention device of door for reinforcement structure}

본 고안은 대형 건축구조물용 도어의 추락방지장치에 관한 것으로서, 좀더 상세하게는 점포, 차고, 물류시설, 변전소 등과 같은 건축구조물 등에 사람이나 차량이 출입할 수 있도록 제어에 따라 승,하강식으로 개폐되는 도어에 있어, 도어를 승,하강 구동시키는 회전축으로부터 동력을 전달하는 구동체인 끊김 발생, 이송체인의 이탈에 의해 발생할 수 있는 도어의 순간 추락을 대처하여 이후에 발생할 수 있는 대형사고를 최대한 방지할 수 있도록 한 것이다.The present invention relates to a fall prevention device of a door for a large building structure, and more specifically, it is opened and closed by a control to allow a person or a vehicle to enter and exit a building structure such as a store, a garage, a distribution facility, a substation, and the like. In the door, it is possible to prevent a large accident that can occur afterwards by dealing with a breakage of the drive chain that transmits power from the rotating shaft that drives the door up and down and a momentary fall of the door that may occur due to the departure of the transfer chain. It would be.

일반적으로 작은 규모의 점포, 차고 등과 같은 각종 생산공장, 물류센터, 또는 대형 건축구조물인 항공기 격납고, 소방서차고 및 변전소 등과 같이 물품의 운반, 보관 등에 유리하도록 차량의 진출이 가능한 대형 도어가 설치된다.In general, a large door is installed to allow the vehicle to move in such a way as to be advantageous for the transportation and storage of goods such as various production plants, distribution centers such as small stores, garages, or large building structures such as aircraft hangars, fire station garages, and substations.

상기와 같이 건축구조물에 설치되는 대형 도어는 통상적으로 작은 점포 등에 설치되는 롤 타입의 셧터 방식에 의해 승,하강 작동이 이루어짐과는 달리, 다수개 의 단위로 된 도어패널을 연속 조합하여 승,하강시킴과 동시에, 상부 내측에서 가이드 상에 그대로 안내되도록 하여 출구를 개방하는 오버헤드 도어(Overhead dood) 가 있고, 또는 도어패널을 단계적으로 상승시킨 다음 상부측에 상승된 도어패널을 출입구의 상부측에 나열 지지시켜 출구를 완전 개방되도록 하는 디펜스 도어(Defense door, 일명 "스태킹 도어" 라고도 함)가 출입구에 적용 설치된다.As described above, a large door installed in a building structure is normally lifted and lowered by continuously combining a plurality of unit door panels, unlike lifting and lowering operations performed by a roll-type shutter method installed in a small store. At the same time, there is an overhead dood which opens the exit by being guided as it is on the guide from the inside of the upper side, or the door panel which is raised on the upper side stepwise and then raised to the upper side of the doorway. A defense door (also called a "stacking door") is installed at the entrance to support the column so that the exit is fully open.

상기와 같이 승,하강 작동하여 출입구를 개폐할 수 있도록 된 오버헤드 도어 및 디펜스 도어는 양자 모두 출입구의 가이드레일이 설치된 상부측으로부터 지지대에 설치된 구동모터 및 감속기를 통해 구비되는 각각 하나 이상 연계되게 설치된 스프라켓 휠을 회전 구동하고, 이 스프라켓 휠을 통해 상기 도어의 양측에 연결된 이송체인을 끌어올리거나 내려주는 동작으로서 도어의 개폐를 운전할 수 있도록 되어있다.As described above, the overhead door and the defense door which are opened and closed to open and close the entrance and exit are both installed in connection with at least one of the drive motor and the reducer provided on the support from the upper side where the guide rail of the entrance is installed. The sprocket wheel is driven to rotate, and the sprocket wheel is driven to raise or lower the transfer chains connected to both sides of the door, so that the door can be opened and closed.

첨부된 도 1은 디펜스 도어를 대표적으로 도시한 것으로서, 양측에 대응되는 지지대(21)에 양측이 설치되어 상기 구동모터(M) 및 감속기(G)를 통해 연결 설치된 제1 내지 제5스프라켓휠(S1~S5) 및 구동체인(C2)을 통해 상호 회전구동하고, 이에 상기 제3스프라켓휠(S3)과 제2스프라켓휠(S2)에 구동체인(C1)으로 연계되어 있는 회전구동축(22)의 회전으로서 상기 지지대(21)의 양측에 대응되게 구비된 제1스프라켓휠(S1)을 구동하여 이송체인(C)으로서 연결 설치된 도어패널(13)을 승강시키거나, 하강시키는 구조로서 운영된다.1 is a representative representation of a defense door, both sides of which are installed on the support 21 corresponding to both sides of the first to fifth sprocket wheels installed through the driving motor (M) and the reduction gear (G) ( S1 to S5 and the driving chain (C2) to rotate each other, and the third sprocket wheel (S3) and the second sprocket wheel (S2) of the rotary drive shaft 22 is connected to the drive chain (C1) As a rotation, the first sprocket wheel S1 provided to correspond to both sides of the support 21 is operated to lift or lower the door panel 13 connected as a transfer chain C.

상기 도어패널(13)은 대형 구조물의 출입구에 설치되어 도어(10)를 형성하는 만큼 상당한 각각 상당한 중량체 이기도 하다.The door panel 13 is also a considerable weight each, as it is installed at the entrance of the large structure to form the door 10.

상기 각각의 도어패널(13)을 연결하고 있는 이송체인(C) 및 도어(10)를 출입구 양측 가이드포스트(11)에 수직 설치되어 이를 수직으로 안내하는 가이드레일(12)은 그만큼 도어패널(13)의 승,하강 운전동작에서 안전에도 직결되어 있다.The guide chain 12 which vertically guides the transport chain C and the door 10 connecting the door panels 13 to the guide posts 11 on both sides of the doorway and vertically guides the doors 13 ) Is directly connected to safety in the up and down operation.

가령, 도어(10)의 하강동작시 상기 제3스프라켓휠(S3)과 제2스프라켓휠(S2)에 연결되어 동력을 전달하는 구동체인(C1) 또는 제4스프라켓휠(S4)과 제5스프라켓휠(S5)을 연결하고 있는 구동체인(C2)이 노후되어 끊김이 발생하게 되거나, 제2스프라켓휠(S2) 및 제3스프라켓휠(S3)로부터 어느 한쪽의 구동체인(C1)이 이탈하는 사례가 발생한다면, 특히 하강 되고 있는 구동모터(M)의 회전구동상태에서 하강되고 있는 도어패널(13)에 순간 가중된다.For example, the driving chain (C1) or the fourth sprocket wheel (S4) and the fifth sprocket connected to the third sprocket wheel (S3) and the second sprocket wheel (S2) to transfer power when the door 10 is lowered. When the driving chain (C2) connecting the wheel (S5) is aged and breakage occurs, or one of the driving chain (C1) is separated from the second sprocket wheel (S2) and the third sprocket wheel (S3) Is generated, the weight is momentarily added to the door panel 13 which is being lowered in the rotational driving state of the driving motor M which is being lowered.

이러한 도어패널(13)은 특히 구동모터(M)가 설치된 지지대(21)측의 구동체인(C1)에서 상기와 같은 문제가 발생하는 경우, 도어패널의 하강속도 균형이 개지면서 순간 하중으로 추락하게 되는 문제점이 있었다.In particular, when the above problem occurs in the drive chain C1 on the side of the support 21 on which the drive motor M is installed, the door panel 13 may fall down due to an instantaneous load while the falling speed balance of the door panel is improved. There was a problem.

결국 상기와 같은 구동체인(C1)의 끊김이나 이탈발생은 제1스프라켓휠(S1)으로부터 이송체인(C)에 의해 각각 연결된 도어패널, 즉 도어(10)를 전반적으로 추락시키는 관계로 얘기치 못한 대형사고를 불러일으키는 문제점이 있었다.As a result, breakage or separation of the driving chain C1 as described above is not possible due to the overall fall of the door panels, that is, the doors 10, which are respectively connected by the transfer chain C from the first sprocket wheel S1. There was a problem that caused a major accident.

상기와 같이 순간 추락하는 도어는 이후 추락으로서 가이드레일 등의 구성요소와 함께 파손되기 때문에 재가동이 어려워져 새로운 도어의 시공이 필요하므로 상기와 같은 추락사고는 손실이 실질적으로 더욱 막대하다.As described above, the door that is temporarily dropped is damaged with components such as a guide rail as a fall later, so it is difficult to restart, and thus, the construction of a new door is necessary.

본 고안은 상기와 같이 제반되는 종래의 문제점을 해결하기 위하여 안출된 것으로서, 대형 건축구조물 등에 사람이나 차량이 출입할 수 있도록 제어에 따라 승,하강식으로 개폐되는 도어에 있어, 도어를 승,하강 구동시키는 회전축으로부터 동력을 전달하는 구동체인 끊김 발생, 이송체인의 이탈에 의해 발생할 수 있는 도어의 순간 추락을 대처하여 이후에 발생할 수 있는 대형사고를 최대한 방지할 수 있는 대형 건축구조물용 도어의 추락방지장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve the conventional problems as described above, in the door that is opened and closed in accordance with the control so that people or vehicles can enter and exit the large building structure, etc., the door is driven up, down The fall prevention device of the door for a large building structure that can prevent a large accident that may occur afterwards by coping with the momentary fall of the door that may be caused by the disconnection of the drive chain that transmits power from the rotating shaft and the transfer chain. The purpose is to provide.

이와 같이 구성된 본 고안의 대형 건축구조물용 도어의 추락방지장치에 대한 작용을 설명하면 다음과 같다.Referring to the operation of the fall prevention device of the large building structure door of the present invention configured as described above are as follows.

먼저, 상술한바 있는 디펜스도어의 운영 시스템에 있어, 도어(10)의 승,하강되는 동작제어는 종래에 기술되었던 구성요소의 기본적인 구성과 동일하게 설치되어 운영됨을 밝힌다.First, in the above-described operating system of the defense door, the operation control of raising and lowering of the door 10 is installed and operated in the same manner as the basic configuration of the components previously described.

상기와 같은 기본적인 설치에 있어, 본 발명에 따른 추락방지수단(100)은 상호 대응되는 지지대(21)에 횡으로 설치되어 구동모터(M) 및 감속기(G)를 통해 구동체인(C2),(C1)을 통해 각 제1스프라켓휠 내지 제5스프라켓휠(S1~S5)을 각각 회전구동하여 도어(10)를 구성하고 있는 도어패널(13)을 이송체인(C)으로써 끌어올려 가이드 포스트(11)측 가이드레일(12)로부터 전반적으로 도어를 개방시키거나, 내리는 동작을 하여 도어(10)로서 출입구를 제어하도록 한다.In the basic installation as described above, the fall prevention means 100 according to the present invention is installed laterally on the support 21 corresponding to each other through the drive motor (C) and the reducer (G) drive chain (C2), ( Each of the first to fifth sprocket wheels S1 to S5 is rotated through C1), and the door post 13 constituting the door 10 is pulled up by the transfer chain C to guide the guide 11. The door is opened or lowered from the side guide rails 12 to control the entrance and exit as the door 10.

상기와 같이 도어(10)를 승,하강시키는 동작을 수회 반복실시함에 있어, 각각의 도어패널(13) 양측에 연결된 제1스프라켓휠(S1)을 통해 도어패널을 승강이나, 하강하는 동작 중 발생할 수 있는 구동체인(C1)(C2)의 노후로 인한 끊어짐 발생, 또는 제2스프라켓휠(S2)과 제3스프라켓휠(S3)로부터 구동체인(C1)이 이탈되는 사례로 인해 도어패널(13)이 순간적으로 추락할 수 있게 된다.In repeatedly performing the operation of raising and lowering the door 10 as described above, it occurs during the operation of lifting or lowering the door panel through the first sprocket wheel S1 connected to both sides of each door panel 13. Door panel 13 due to breakage caused by the deterioration of the drive chain (C1) (C2), or the drive chain (C1) is separated from the second sprocket wheel (S2) and the third sprocket wheel (S3) You can fall at this moment.

상기 지지대(21)측으로부터 제2스프라켓휠(S2)의 회전축(23)상에 설치되어 이송체인(C)이 치합하는 제1스프라켓휠(S1)은 그대로 하강하는 도어패널(13)의 무게가 가세되어 추락과 동시에 과속 회전하게 된다.The weight of the door panel 13 which is installed on the rotation shaft 23 of the second sprocket wheel S2 from the support 21 side and the first sprocket wheel S1 to which the transfer chain C is engaged is lowered as it is. In addition to the fall, and at the same time the speed of rotation.

상기와 같은 과속회전은 각 댕으되는 지지대(21)로부터 제1스프라켓휠(S1), 제2스프라켓휠(S2)이 설치된 회전축(23)상에 연계된 추락방지수단(100)의 동작으로서 상기 회전축(23)의 회전을 정지시켜 줌으로써 낙하되는 도어패널의 추락을 방지할 수 있게 한다.The speed rotation as described above is the operation of the fall prevention means 100 associated with the rotating shaft 23, the first sprocket wheel (S1), the second sprocket wheel (S2) is installed from the support 21 to each other. By stopping the rotation of the rotary shaft 23 it is possible to prevent the fall of the door panel falling.

상기 도어패널이 순간적으로 추락되는 시점에서 그 속도가 300mm/sec 이상의 강하속도가 발생하면, 추락방지수단(100)의 내부에 설치된 구성요소를 구동시키게 된다.When the falling speed of 300mm / sec or more occurs at the time when the door panel is instantaneously dropped, the components installed inside the fall preventing means 100 are driven.

추락방지수단(100)은 상기 회전축(23)과 연결되어 평상시에는 정회전 또는 역회전을 실시하다가, 상술한 바와 같은 사례로 도어패널이 추락하는 사고가 발생하는 경우는, 도시된 도 6에서 도시된 바와 같이, 상기 회전연결축(110)과 함께 회전하는 회전판(120)상의 스톱퍼(130)가 고정축(121)을 중심으로 원심력발생에 의해 외측으로 벌어지는 동작을 취하게 된다.The fall preventing means 100 is connected to the rotary shaft 23 to perform the normal or reverse rotation in normal times, and in the case of the above-described case, the accident that the door panel falls, as shown in FIG. As described above, the stopper 130 on the rotating plate 120 that rotates together with the rotary connecting shaft 110 takes an operation that is opened to the outside by the centrifugal force generated around the fixed shaft 121.

상기 스톱퍼(130)는 평상시 고정핀(122)에 일측이 지지되어 있는 상태에서 회전판(120)에 원심력이 가해지는 상태에서 양단이 연결 설치된 인장스프링(40)은 원심력보다 그 인장력이 낮아 상호 인장됨과 동시에, 연속되는 원심력작용으로서 스톱퍼(130)의 일단은 고정블럭(150)상의 걸이턱(151)에 걸려 순간적인 회전을 방지시킨다.The stopper 130 is a tension spring 40 is installed at both ends in the state where the one side is supported on the fixed pin 122 in the state where the centrifugal force is applied to the rotating plate 120, the tensile force is lower than the centrifugal force is mutually tensioned and At the same time, one end of the stopper 130 as a continuous centrifugal force is caught by the hook 151 on the fixed block 150 to prevent instantaneous rotation.

즉, 회전판(120)상의 각각 스톱퍼(130)로 인해 회전판(120)이 정지되는 상태는 덮개(160)의 통공(161)과 지지커버(170)를 관통하고 있는 회전연결축(110)이 회전축(23)과 연결되어 있는 이유에서 회전축(23)과 함께 정지되는 동작을 취하게 된다.That is, in the state in which the rotating plate 120 is stopped by the stopper 130 on the rotating plate 120, the rotary connecting shaft 110 penetrating through the through hole 161 and the support cover 170 of the cover 160 is the rotating shaft. The reason why it is connected with 23 is to stop the movement together with the rotary shaft 23.

결국, 이때부터는 구동체인(C1)과 관계없이 제1스프라켓휠(S1), 제2스프라켓휠(S2)의 회전을 강압적으로 정지시켜줌으로써, 낙하되는 도어패널(13)이 연속되는추락을 방지하여 대형 안전사고에 대처할 수 있게 된다.As a result, at this time, by stopping the rotation of the first sprocket wheel (S1), the second sprocket wheel (S2) irrespective of the drive chain (C1), thereby preventing the falling door panel 13 to fall continuously. Can cope with large safety accidents.
