본 고안은 아파트나 고층건물의 옥상에 설치되어 화물등을 승ㆍ하강시키는 곤도라 안전확인장치의 구조에 관한 것으로, 특히 곤도라의 고리대와 건물옥상의 앙카에 연결되는 링크체인사이에 안전확인장치가 갖추어진 곤도라 안전확인장치의 구조에 관한 것이다.The present invention relates to a structure of a gondola safety check device which is installed on a roof of an apartment or a high-rise building to lift and lower cargo, and in particular, a safety check device is provided between the gondola ring and the link chain connected to the anchor on the building roof. It is about the structure of the Jin Gondola safety check device.
일반적으로 고층건물의 옥상에 설치된 곤도라는 케이지(Cage)에 화물을 적잭하여 승ㆍ하강시키도록 되어져있는바, 상기 케이지에 화물을 적재할 경우 발생되는 회전토오크에 의해 곤도라가 전복될 위험성을 내포하고 있다.In general, the gondola installed on the roof of a high-rise building is designed to lift and descend cargo by loading the cargo into a cage, which implies the risk of the gondola overturning due to the rotational torque generated when loading the cargo into the cage. have.
따라서 종래에도 상기와 같은 곤도라의 전복위험성을 제거하는 수단으로 건물옥상지면에 고정구조물인 앙카를 설치하고, 곤도라의 후방양측단에 고리대를 형성하여 고리대사이에 링크 체인이 연결되어야만 장비가 작동되어지는 안전확인장치(실용신안동록출원 제87-8150호)나, 제3도(A),(B)에 도시된 바와같이 곤도라(21)후면에 힌지축(22a)을 중심으로 회동성을 갖는 고리대(22)가 스프링(22b)으로 탄설되고 그 선단에 접지단(30a)이 형성되어 있어서 앙카(3)와 링크체인(24)연결시, 상기 링크체인(24)이 자체하중이나 이에 부하되는 장력에 의해 고리대(22)가 회동되면서 접지단(30a)이 스위치(29)의 접지단(29a)과 접촉되어야만 장비가 작동되는 곤도라 안전확인장치의 구조과 사용되어온 것이 주지의 사실이다.Therefore, in the past, as a means of eliminating the risk of overturning the gondola, an anchor, which is a fixed structure, is installed on the ground of the building roof, and a link chain is formed at both rear ends of the gondola so that the link chain is connected between the hooks. Ring stand having pivotability around the hinge shaft 22a on the rear of the gondola 21 as shown in the safety confirmation device (Utility Sindong-dong Application No. 87-8150) or 3 (A) and (B). (22) is piled up with the spring (22b) and the ground end (30a) is formed at the tip thereof when the anchor (3) and the link chain 24 is connected, the link chain 24 is a self-load or a tension to be loaded thereon It is well known that the gondola safety check device has been used to operate the equipment only when the ground end (30a) is in contact with the ground end (29a) of the switch 29 as the ring 22 is rotated by.
그러나 종래 안전확인장치의 구조는 링크체인의 자중만으로도 고리대가 회동되면서 접지단들이 상호접촉되어져 곤도라가 작동되는 사례가 많아 링크체인상의 정확한 장력조절이 어렵고, 또한 이로 인하여 링크체인이 느슨하게 연결된 상황에서 화물을 적재하게 되면 곤도라가 전면지지대을 중심으로 회전토오크가 발생되어 후면지지대가 들리면서 건물옥상지면에 매설된 앙카에 충격을 주어 방수층을 손상시키게 되고, 화물이 제거되는 순간에는 곤도라의 자중이 건물옥상으로 내려않는 충격으로 건물옥상지반이 함몰되거나 크랙(Crack)을 초래하게 되는 등의 위험성이 있어왔다.However, in the structure of the conventional safety check device, since the hooks are rotated only by the weight of the link chain, the ground end is contacted with each other, so the gondola is often operated, so that it is difficult to precisely adjust the tension on the link chain. When the gondola is loaded with a rotating torque around the front support, the rear support is lifted, impacting the anchor buried in the roof of the building, damaging the waterproof layer. There has been a risk that the impact of falling down will cause the roof of the building to collapse or cause cracks.
이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로서, 곤도라가 설치된 건물옥상지반 및 방수층에 아무런 충격도 주지않으면서 정확하게 링크체인이 연결되어진 상태에서만 장비가 작동되어지고, 이를 지상의 작업자가 간편하게 인지하도록 되어져서 안전성이 크게 향상되어진 곤도라 안전확인장치의 구조를 제공하는데 그 목적이 있다.The present invention has been devised to solve the above problems, the equipment is operated only when the link chain is correctly connected without giving any impact to the building roof and the waterproofing layer on which the gondola is installed, and the worker on the ground Its purpose is to provide a structure of a gondola safety check device that can be easily recognized and greatly improved in safety.
상기와 같은 목적을 달성하기 위해 본 고안은 곤도라의 고리대와 링크체인사이에 스프링에 의태 탄설된 고리단들을 연결하여, 쟈키를 상하이동시킴으로서 링크체인상에 일정이상의 장력이 작용되어 스프링이 압착되고 내설된 공지의 리미트스위치가 접속되면서 장비를 작동해도 좋다는 안전확인표시가, 경보나 램프의 점등의 표시수단으로 지상의 작업자에게 인지되어 안전하게 장비의 작동이 가능하도록 되어진다.In order to achieve the above object, the present invention connects the end of the spring loaded by the linkage between the gondola and the link chain. The safety check mark indicating that the equipment may be operated while the known limit switch is connected is recognized by an operator on the ground as an indication means of alarm or lighting of the lamp, so that the equipment can be operated safely.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 곤도라의 부분개략측면도로서, 본 고안은 곤도라(1)후면의 고리대(2)와 건물옥상지면에 매설된 앙카(3)에 한쪽단이 연결고정되는 링크체인(4)사이에 안전확인장치(A)가 설치되어진 것으로서, 제2도에 도시된 바와같이 상기 안전확인장치(A)는 중공(中空)의 원통형 케이스(6)의 개구된 상ㆍ하부에 상ㆍ하부덮개판(7a,7b)이 체결용 수단에 의해 고정설치되어지되, 상부덮개판(7a)의 전ㆍ후면에는 고리구멍(8c)을 갖춘 상부연결 고리단(8a)과 공지의 리미트스위치(9a)가 내설된 스위치부(9)가 일체로 고정설치되어진다.1 is a partial schematic side view of the gondola according to the present invention, the present invention is a link chain (4), one end of which is fixed to the hook (2) on the rear of the gondola (1) and the anchor (3) buried in the building roof surface The safety confirmation device A is provided between the upper and lower covers of the upper and lower openings of the hollow cylindrical case 6, as shown in FIG. The plates 7a and 7b are fixedly installed by means of fastening, but the upper and rear ends of the upper cover plate 7a are provided with an upper connection ring end 8a having a ring hole 8c and a known limit switch 9a. The switch portion 9, which is built in, is fixedly installed.
또한 하부덮개판(7b)의 중앙에는 상부연결 고리단(8a)과는 90°회전된 위치에 놓여진 하부연결 고리단(8b)하단이 삽입되어지되, 이 하부연결 고리단(8b)의 하단에 단이지게 샤프트(10)끝단에는 스프링지지턱(10a)이 형성되고, 이 스프링지지턱(10a)에는 스프링(11)이 안착되어지는 한편, 상ㆍ하부고리단(8a,8b)은 모두 직사각형 단면형상으로 되어져 상부연결 고리단(8a)은 고리대(2)와 연결이 용이하게 되며 하부연결 고리단(8b)은 회동되면서 링크체인(4)이 꼬이는 것은 방지하도록 되어진다.In addition, the lower end of the lower cover plate (7b) is inserted into the lower end of the lower connecting ring end (8b) is placed in a position rotated 90 ° with the upper connecting ring end (8a), the lower end of the lower connecting ring end (8b) At the end of the shaft 10, a spring support jaw 10a is formed, and the spring support jaw 10a has a spring 11 seated thereon, while the upper and lower ring ends 8a, 8b have a rectangular cross section. The upper end of the hook (8a) is easy to connect with the hook 2, the lower end of the hook (8b) is rotated to prevent the link chain (4) is twisted.
따라서 상기와 같은 구조로 된 본 고안은 곤도라(1)의 고리대(2)에 상부연결 고리단(8a)이 연결되고 하부연결 고리단(8b)에는 앙카(3)와 연결된 링크체인(4)의 한쪽단이 연결된 후 쟈키(5)로 상기 곤도라(1)의 높이를 조정하게 되는데, 이때 일정한 장력이상이 링크체인(4)에 부하되면 양쪽연결 고리단들(8a,8b)이 화살표방향인 상호 상ㆍ하향으로 이동되면서 스프링(11)을 압착하게 되어 스위치부(9)가 스프링지지턱(10a)에서 분리되면 공지의 리미트스위치(9a)가 작동되어 지상의 작업자가 휴대하고 있는 장비작동구동용 리모톤상에 램프가 점등되거나 경보음을 울리게 되어 링크체인(4)의 올바른 연결상태를 쉽게 인지할 수 있도록 되어진다.Therefore, the present invention having the structure as described above of the link chain (4) of the upper connecting ring end (8a) is connected to the ring base (2) of the gondola (1) and the anchor link (3) connected to the lower connecting ring end (8b) After one end is connected, the height of the gondola 1 is adjusted by the jockey 5. At this time, when a certain tension or more is loaded on the link chain 4, both connecting ring ends 8a and 8b are mutually in the direction of the arrow. When the spring 11 is squeezed while being moved up and down, and the switch unit 9 is separated from the spring support jaw 10a, a known limit switch 9a is operated to operate the equipment operated by the ground worker. The lamp on the remote control lights or sounds an alarm so that the correct connection status of the link chain 4 can be easily recognized.
그러므로 상기와 같은 본 고안은 고리대와 앙카를 연결하는 링크체인이 팽팽하게 연결되어 일정한 장력을 갖기전에는 장비가 가동될 수 없도록 됨으로써, 곤도라의 유동성을 줄여 화물적재에 따른 곤도라의 회전토오크로 인해 건물옥상지반 및 방수층에 손상을 주지 않으면서 장비작동상의 안전성이 향상되어지는 잇점을 갖게된다.Therefore, the present invention as described above, the link chain connecting the ring and the anchor is tightly connected so that the equipment cannot be operated until it has a constant tension, reducing the fluidity of the gondola due to the rotation torque of the gondola due to cargo loading This has the advantage that the safety of equipment operation is improved without damaging the ground and the waterproof layer.
