이를 도면에 의거하여 상세하게 설명하면 다음과 같다.This will be described in detail with reference to the drawings as follows.

굴뚝(14)이나 송전용 철탑과 같은 고소 구조물에 설치된 승강용 계단(15)에 수직 추락방지용 레일(rail)(1)을 설치하되(도3 참조), 레일(1)의 양쪽 측면부에는 바(bar)(1a)를 형성하며 상기 바(1a)에는 레일(1)을 승강용 계단(12)에 체결하는 체결간(2)과 레일(1)의 연결 설치 시에 사용하는 연결편(3)이 연결 볼트(4)에 의해체결되며, 상기 레일(1)에 장착되어 추락을 방지하는 트로리(trolley) 몸체(5)의 하단부에는 4개의 바퀴(6)가 좌우측에 각각 장착되고 트로리 몸체(5) 중앙에 형성된 트임부(5a)에는 "L"자 형상으로 된 고정구(9)가 스프링(7)과 샤프트(8)에 의해 힌지(hinge) 방식으로 설치되고, 고정구(9)의 상부에는 통상의 추락방지용 벨트(10)가 수지로 된 포대에 절첩형으로 내장되어 형성한 업소버(absorber)의 선단측 체결부(10a)가 체결되고, 상기 업소버의 타측단에는 작업자가 착용한 안전띠나 안전용 자켓에 연결된 구명용 로프와 체결하는 체결구가 형성되어진 것이다.A vertical fall prevention rail 1 is installed on the lifting stairs 15 installed in a high-rise structure such as a chimney 14 or a transmission pylon (see FIG. 3). Bar (1a) is formed in the bar (1a) is a fastening section (2) for fastening the rail (1) to the lifting stairs 12 and the connecting piece (3) used in the connection installation of the rail (1) Fastened by connecting bolts (4), four wheels (6) are mounted on the left and right sides of the trolley body (5) mounted on the rail (1) to prevent falling, and the trolley body (5). A fastener 9 having an “L” shape is provided in the center portion of the trimmed portion 5a in a hinged manner by the spring 7 and the shaft 8. The fastening side fastening portion 10a of the absorber formed by folding the fall preventing belt 10 in a resin bag is fastened, and the work is performed on the other end of the absorber. It would have been formed fastening members for fastening and for nine people connected to a seat belt or safety jacket worn rope.

상기와 같이 구성된 본 발명의 실시예는 다음과 같다.Embodiments of the present invention configured as described above are as follows.

굴뚝(11)이나 송전철탑과 같은 고소 구조물에 설치된 승강용 계단(12)에 레일(1)을 수직으로 장착하고 상기 계단(12)에 개재된 상기 트로리 몸체(5)를 앞으로 제치면, 이의 하단부에 힌지 설치된 고정구(9)가 레일(1)의 바닥면에서 해지되어 트로리 몸체(5)가 용이하게 앞으로 진행하게 되나, 작업자가 추락하는 경우와 같이 추락자의 체중에 의해 트로리 몸체(5)가 뒤로 제쳐질 때에는 상기 "L"형고정구(9)가 레일(1)의 바닥면에 밀착되어 걸림됨에 따라 상기 트로리 몸체(5)는 레일(1)에서 밀려나지 않게 되므로 추락을 방지할 뿐만 아니라 상기 업소버의 절첩된 벨트가 수지 포대에서 펼쳐지면서 추락 시의 충격을 완충시켜 안전사고를 방지하게 되는 것이다.When the rail 1 is vertically mounted on the elevating staircase 12 installed in a high-rise structure such as a chimney 11 or a transmission tower, and the front of the trolly body 5 interposed on the staircase 12 is forward, the lower end thereof The fastener 9 installed in the hinge is released from the bottom surface of the rail 1, so that the trolley body 5 easily moves forward, but the trolley body 5 is moved backward by the weight of the faller, such as when a worker falls. When the “L” type fixture 9 is abutted, the trolley body 5 is not pushed away from the rail 1 as it is held in close contact with the bottom surface of the rail 1, thereby preventing the fall as well as the absorber. Folded belt of the unfolds from the resin bag to cushion the impact of the fall to prevent safety accidents.

상기한 바와 같이 본 발명은 고소 작업자의 추락 사고를 방지하는 수직 추락방지 시스템에 있어서, 굴뚝이나 송전철탑 등의 승강용 계단의 일측에 트로리(trolley)몸체(5)가 장착된 레일(1)을 설치하여 고소 작업자가 추락 시 추락자의 체중이 수직 방향으로 작용하면서 상기 트로리 몸체(5)에 설치된 고정구(9)가 레일(1)에 걸림되어 작업자의 추락방지 및 충격을 흡수할 수 있는 것으로, 이는 구조가 간단하고 설치가 간편하여 매우 실용적일 뿐만 아니라 산업 재해의 방지에 크게 기여할 수 있는 것이다.As described above, the present invention is a vertical fall prevention system for preventing a fall accident of a height worker, a rail (1) equipped with a trolley body (5) on one side of the lifting stairs, such as chimneys and transmission towers When the height of the fall falls down the worker's weight acts in the vertical direction, the fastener 9 installed on the trolley body 5 is caught on the rail 1 to prevent the fall of the worker and absorb the impact, which is Its simple structure and easy installation make it very practical and can greatly contribute to the prevention of industrial accidents.
