Description
Устройство работает следующим образом.The device works as follows.
Опорные колонны 6, 7 и 9 выдвигаютс с помощью подъемников 4, 5 и 8 в море параллельно продольной оси платформы. После перехода центра т жести опорных колонн за оси качани подъемников нижние концы колонн , поддерживаемые водоизмещающими баллонами, начинают затапливатьс , и колонна стремитс приобрести вертикальное положение . При этом выдвижение плунжеров гидроцилиндров 12 задает начальный угол наклона опорных колонн к вертикали. Затем действием цилиндров 10 опорные колонны 6 и 7, ведомые турел ми 2 и 3 с подъемниками 4 и 5 разворачиваютс до ограничительных выступов 11 корпуса и располагаютс по отношению друг к другу под углом 120° или под углом 60° между ос ми качани подъемников. После этого опорные колонны опускаютс до дна мор , плунжеры гидроцилиндров 12 вт гиваютс , а корпус платформы с помощью подъемников 4, 5 и 8 поднимаетс над уровнем мор на заданную высоту.The supporting columns 6, 7 and 9 are extended with the help of lifts 4, 5 and 8 into the sea parallel to the longitudinal axis of the platform. After the transfer of the center of gravity of the support columns beyond the swing axis of the lifts, the lower ends of the columns, supported by the displacement balloons, begin to flood, and the column tends to acquire a vertical position. In this case, the extension of the plungers of the hydraulic cylinders 12 sets the initial angle of inclination of the supporting columns to the vertical. Then, by the action of cylinders 10, support columns 6 and 7, driven by turrets 2 and 3 with elevators 4 and 5, unfold to the limiting projections of the hull 11 and are positioned relative to each other at an angle of 120 ° or at an angle of 60 ° between the axis of the elevators. After that, the supporting columns are lowered to the bottom of the sea, the plungers of the hydraulic cylinders 12 are retracted, and the platform body is lifted to the specified height by means of lifts 4, 5 and 8.
Перевод платформы из рабочего в транспортное положение производитс в обратномThe transfer of the platform from the worker to the transport position is performed in the opposite direction.
пор дке. При этом опорные колонны укладываютс в горизонтальном положении на платформу параллельно друг другу, что позвол ет увеличить остойчивость платформы в транспортном положении и уменьщить ветровое сопротивление нри буксировке.order In this case, the support columns are laid in a horizontal position on the platform parallel to each other, which makes it possible to increase the stability of the platform in the transport position and reduce the wind resistance when being towed.
