GRIPPING DEVICE FOR THE SILTED UNDERWATER OBJECTS AND THE METHOD OF ITS USE, WHILE PERFORMING THE LIFTING Russian patent published in 2017 - IPC B63C7/20 B63C7/06 B63C7/04 

FIELD: transportation.

SUBSTANCE: proposed gripping device for the silted underwater objects lifting and the method of its use. The gripping device contains the horizontal and vertical sections, on the lower parts of which the movable support brackets are provided, with the possibility to form the support prism for the object to be lifted, when these brackets are brought up under it. The vertical sections are made in the form of the tubular rods, which are located in the plan along the circle and have the hinged connection with the corresponding support brackets, each of which has the protuberance, that prevents the bracket from turning in the outer direction. The gripping device is lowered on the underwater object by penetration of vertical rods with unidirectional supporting brackets in silt. To keep the movement, close to rectilinear, use the ballast tanks installed on the periphery of the horizontal section. After penetration of the gripping device to the required depth with the help of the hydraulic power cylinder, choose the internal cargo slings before the support brackets reach the bottom of the lifted object.

EFFECT: improved performance of the gripping device for lifting the silted underwater objects, increase of the underwater technical operations efficiency.
