Description

54) ПРЕДОХРАНИТЕЛЬНОЕ УСТРОЙСТВО ВОРОТ ШЛЮЗА 8 Предохранительное устройство работает следующим образом. При подъеме преграды 1 в верхнее положение дл пропуска судна она ослабл етс гидравлическими амортиз торами 3. Включаютс лебедки 8 на подъем. Рычаги 6 поворачиваютс вокруг осей 7 вверх. Блоки И соприкасаютс с преградой и поднимают ее. В свою очередь преграда приходит в соприкосиовение с блоками 12. По достижении крайнего верхнего положе ни рычагов 6 лебедки 8 отключаютс Гидравлические амортизаторы 3 прекращают ослабление преграды. Дл установки преграды в рабочее положение включаютс лебедки 8 и ослабл ютс канаты 9. Рычаги 6 своим весом и преграды поворачиваютс около осей 7,.опускают блоки 11 с наход щейс на них преградой в нижне положение. По достижении рычагами 6 нижнего конечного положени лебедки 8 от ключают с . В процессе опускани рычагов 6 гидравлические амортизаторы 3 нат ги вают преграду 1, по достижении преградой 1 конечного рабочего положени блоки 11 и 12 выход т из соприкосновени с ней.54) SAFETY DEVICE DOORS OF THE GATEWAY 8 The safety device operates as follows. When lifting obstacle 1 to the upper position for passing a ship, it is weakened by hydraulic shock absorbers 3. Winch 8 is activated. The levers 6 rotate around the axles 7 upwards. Blocks And touch the barrier and lift it. In turn, the obstacle comes in contact with the blocks 12. When the extreme upper position of the levers 6 is reached, the winch 8 is turned off. Hydraulic shock absorbers 3 stop the weakening of the obstacle. In order to place the obstacle, the winches 8 are turned on and the ropes 9 are loosened. The levers 6, by their weight and the obstacles, turn about the axes 7, lower the blocks 11 with the obstacle on them to the lower position. When the levers 6 reach the lower end position of the winch 8 from the key c. In the process of lowering the levers 6, the hydraulic shock absorbers 3 pull the obstacle 1, when the barrier 1 reaches the final operating position, the blocks 11 and 12 come out of contact with it.

Claims

10 74 When the ship is piled on a flexible barrier 1, the rods 2, thrown out of the cylinders of the hydraulic shock absorbers 3, cause the oil to overflow through the safety valves installed in the shock absorbers 3 from the rod into the piston cavities, creating resistance to the movement of the vessel. Claim 1. The safety device of the gate of the gateway, including a flexible drive barrier mounted on its foundations and hydraulic shock absorbers, different from the fact that, in order to increase operational reliability, racks are mounted on the bases of the gateway, on which the arms connected with obstacle through the cable system.

2. The device according to claim 1, characterized in that the hinges of the levers are located above the level of the working position of the flexible barrier at half the height of its rise. Sources of information taken into account in the examination: 1. The patent of Germany No. 1805216, cl. 84tl / 10, 1966.
