FIELD: construction.SUBSTANCE: safety device of sluice gates is designed for protection of sluice gates against impact of vessels. The safety device comprises a flexible barrier with shock absorbers, two beams that rotate in the horizontal plane and a truss with drives. Two rotary beams are hingedly fixed on opposite sides of the sluice. The rotary truss is installed on one of the rotary beams. The flexible barrier comprises two ropes. Some ends of ropes are connected to shock absorbers. On free ends of ropes there are elements of a coupling unit. Each rope is equipped with stops. Stops, interacting with ends of rotary beams, provide during assembly the necessary tension of ropes. During installation of a barrier device, rotary beams and truss turn by drives perpendicularly to the sluice in one line. Free ends of two ropes are coupled with a coupling unit. The rotary truss turns with a drive relative to the rotary beam to the side opposite to the impact of the vessel, leaving the rope freely sagging only between rotary beams. Reduced capacity of drives and mass of metal structures is achieved by installation of beams and truss, which are rotary in the horizontal plane.EFFECT: reduced force of rope tension is achieved by reduction of length of a rope freely sagging between rotary beams.6 dwg |
