| description | The present invention relates to an aerial work ladder fall prevention apparatus for a tank, which is able to connect a safety vest of a worker by a rope with a safety rail detachably engaged with an aerial work ladder through a stopper, and prevent the fall of the worker by letting the stopper hung on a sawtooth unit of the safety rail when the worker falls. To this end, according to the present invention, the aerial work ladder is installed on the front surface of a tank installed at a high place vertically or horizontally. The ladder has stair rods placed in multiple steps between a pair of supporters extended up to an upper side of the tank, and has a backrest unit formed in a semi-circular arc shape to support the back of the worker from a point 2.5 meters up from the ground surface up to the upper side of the tank. The safety rail is detachably placed near one of the supporters of the ladder. The safety rail is made in plate shape with a broader width than the thickness, and is placed near the one supporter. On a side surface in a widthwise direction, a rail groove penetrating both side surfaces is formed in a longitudinal direction. On a front surface, sawtooth units are formed in multiple steps to be opened upward. The stopper made by folding a rod into "ㄷ" shape includes: a hinge unit formed on one side to be inserted into the rail groove of the safety rail; and a hanging unit formed to be hung on the sawtooth units on the other side. The stopper is firmly engaged with the safety rail through a nut fastened with a screw on an end of the hinge unit. An end of the hanging unit is connected to the safety vest of the worker by a rope, so when the worker falls, the stopper is rotated around the hinge unit, and the hanging unit hangs on the sawtooth units.
본 발명은 고소작업용 사다리에 탈착식으로 결합되는 안전레일에 스토퍼를 통하여 작업자의 안전조끼를 로프로 연결함으로써, 작업자의 추락시 스토퍼가 안전레일의 톱니부에 걸려서 작업자의 추락이 방지되도록 한 탱크용 고소작업 사다리 추락방지장치에 관한 것이다. 이를 위하여 본 발명은 수직 또는 수평으로 높게 설치되는 탱크의 전면에 고소작업용 사다리가 설치되고, 상기 사다리는 탱크 위쪽까지 연장된 한쌍의 지지대 사이에 계단봉이 다단으로 구비되며, 지면에서 2.5미터 되는 지점부터 탱크의 위쪽까지 작업자의 등을 받쳐주는 등받이부가 반원호형으로 형성된 탱크용 고소작업 사다리 추락방지장치에 있어서, 상기 사다리의 한쪽 지지대에 근접되게 탈착식으로 안전레일이 구비되는데, 상기 안전레일은 두께 보다 폭이 넓은 판재형으로 구성되어서 상기 한쪽 지지대에 근접 설치되고, 폭 방향 측면에는 양쪽 측면을 관통하는 레일홈이 길이방향을 따라 형성되며, 전면에는 상향으로 개방된 톱니부가 다단으로 형성되고; 환봉을 "ㄷ"형으로 절곡한 스토퍼는 한쪽이 상기 안전레일의 레일홈에 끼워지는 힌지부로 구성되고, 반대쪽은 상기 톱니부에 걸리는 걸림부로 구성되며; 상기 힌지부 끝단의 나사에 체결되는 너트를 통하여 상기 스토퍼는 헐겁지 않게 안전레일에 결합되고, 상기 걸림부 끝단은 작업자의 안전조끼와 로프로 연결되어서 작업자의 추락시 상기 스토퍼가 힌지부를 중심으로 회동되면 상기 걸림부가 톱니부에 걸 |
