FIELD: engineering equipment.
SUBSTANCE: invention relates to devices of overcoming water barriers, in particular to floating bridges and ferries. The device for automatic fixation of the middle pontoons of the river link of the pontoon park comprises a coupling arm, a pin with a hook notch. Inside one of the middle pontoons of the river link, a metal bracket is mounted on its internal elements, in the cavity of which, in its middle part, a coupling arm is installed by means of a hinge joint, made in the form of two metal plates parallel to each other, the ends of which are connected by a pin. The lower part of the metal bracket is connected by means of a spring to a roller mounted in the middle part of the coupling arm, coaxially towards it, inside the adjacent pontoon of the river link, a pin with a hook notch is mounted, pivotally connected by means of a rod and arm to the internal elements of the middle pontoon and located in the cavity of the restrictive box, containing in the lower part along the edges two rollers adapted for free rotation. To fix and move the coupling arm, on the internal elements of the middle pontoon, a coupling arm stop is mounted, made in the form of a shaft, on which the coupling arm and the disengagement lever, consisting of a support, a rod and a handle, rest.
EFFECT: reduction of labour and time costs when fixing the middle pontoons of the river link of the pontoon park in the open position.
