Description

고가 사다리차An elevated ladder
본 발명은 고가 사다리차에 관한 것으로서, 보다 상세하게는 아웃트리거의 중량을 가중시키므로 사다리를 길게 펼쳐 작업을 행할 때 차량의 유동이나 전도 등의 위험성을 감소시키고 안정된 지지력을 유지하는 것이 가능하도록 구성한 고가 사다리차에 관한 것이다.The present invention relates to an elevated ladder vehicle, and more particularly, to increase the weight of the outrigger, the ladder ladder is configured to reduce the risk of the flow or fall of the vehicle and to maintain a stable supporting force when the ladder is extended to work long It is about.
산업사회가 발달하고 도시의 인구집중화현상이 발생하면서 고층건물의 신축이 점차 증가하는 추세이며, 근래 들어 낮게는 대략 30~40층 정도에서부터 높게는 대략 60~100층 정도에 이르는 고층건물이 신축되거나 신축이 예정되어 있다.As the industrial society develops and the city's population concentration occurs, the construction of high-rise buildings is gradually increasing. Recently, high-rise buildings ranging from about 30 to 40 floors to about 60 to 100 floors have been newly built. New construction is planned.
상기 고층건물은 용적률을 높임으로 인한 공지면적의 증가나 수용인원의 증가 등의 측면에서 저층건물에 비해 유리한 점이 매우 많은 편이지만, 고층에서 화재 발생시 화재진압이나 인명구조 등이 쉽지 않으며 이삿짐 등의 화물 운반 등을 행하기 어려운 등의 단점이 있다.The high-rise buildings have many advantages over low-rise buildings in terms of increasing the known area due to increasing the volume ratio or increasing the number of people, but it is not easy to extinguish fire or rescue people when a fire occurs in high-rises. There are disadvantages, such as being difficult to carry.
종래 고층건물의 화재 진압이나 인명구조, 화물 운반 등의 고소작업을 위해서는 고가 사다리차를 주로 이용하게 되며, 이 고가 사다리차는 운전자가 탑승하여 운전을 행하는 탑승석이 구비되는 차량과, 상기 차량의 탑승석 후방쪽에 설치되는 베이스프레임과, 상기 베이스프레임의 상부에 설치되고 평상시 짧게 단축된 상태에서 현장에서 길게 늘어나는 신축사다리와, 상기 베이스프레임의 앞쪽 및 뒤쪽에 한 쌍씩 각각 설치되고 차량의 좌측과 우측으로 다단으로 길이가 신축되는 두 쌍의 아웃트리거로 구성된다.Conventional high-rise ladders are usually used for high-altitude operations such as fire suppression, lifesaving, and cargo transportation, and the elevated ladder cars are provided with vehicles in which a driver's seat is provided and a driver's seat is used for driving. Base frame is installed on the side, and installed on top of the base frame and stretched long stretch in the field in the shortened state usually short, and a pair in each of the front and rear of the base frame, respectively installed in multiple stages to the left and right of the vehicle It consists of two pairs of outriggers that stretch in length.
상기와 같이 구성되는 종래 고가 사다리차는 고층건물의 화재진압이나 인명구조, 화물운반 등 고소작업을 위해 신축사다리를 길게 연장하면 연장할수록 무게 중심이 점점 위쪽에 분포하게 되므로 지지력이 약해지기 쉽다.Conventional elevated ladder cars configured as described above are prone to weakened bearing capacity as the center of gravity is gradually distributed upwards as the extension ladder is extended for a firefighting of high-rise buildings or lifesaving operations such as cargo transportation.
특히 고층건물이나 초고층건물의 증가로 인해 이러한 고층 및 초고층건물에서 고가 사다리차를 이용하는 사례가 증가함에 따라 신축사다리의 늘어나는 길이도 점차 증가하는 추세이다.In particular, due to the increase in high-rise buildings and high-rise buildings, the use of high-ladders in these high-rise and high-rise buildings is increasing, the increasing length of the ladder is gradually increasing.
그런데 상기와 같이 신축사다리의 늘어나는 길이가 점차 증가함에 따라 고소작업을 위해 신축사다리의 길이를 길게 연장하는 경우 지지력이 점점 약해지게 되며 바람 등의 외부영향이 작용하는 경우 등에 있어서는 지지력이나 안정감이 현저히 저하되는 것에 의하여 차량이 넘어지거나 전도되는 등의 사고가 발생할 우려가 크므로 안정감을 보다 향상시킬 수 있는 기술에 대한 연구개발이 필요한 실정이다.However, as the extension length of the extension ladder increases as described above, the extension of the extension ladder length for the height work becomes weaker, and in the case of an external influence such as wind, the support force or stability is significantly lowered. Due to the high risk of accidents such as falling of the vehicle or falling over, there is a need for research and development on a technology that can further improve stability.
본 발명은 상기와 같은 점에 조감하여 이루어지는 것으로서, 아웃트리거에 중량가중부재를 설치하여 높은 하중을 부여하므로 소방작업 등을 위해 신축사다리를 길게 연장하여 작업하는 경우 유동이나 전도 등의 우려를 감소시키고 고층건물에서 초고층건물에 이르기까지 안정된 상태로 작업가능한 고가 사다리차를 제공하는 데, 그 목적이 있다.The present invention is made in view of the above point, and by installing a weight-weighted member on the outriggers to give a high load, when working with long stretched ladders for firefighting work, such as reducing the risk of flow or conduction It is an object of the present invention to provide an elevated ladder truck that can work in a stable state from a high-rise building to a high-rise building.
