Rotator towfish retracting/releasing device

Abstract

The invention provides a rotator towfish retracting / releasing device. The rotator towfish retracting / releasing device comprises a mounting base on which a plurality of upright columns are arranged; the rotator towfish retracting / releasing device is characterized in that guide rails are arranged on the top ends of the plurality of upright columns, a trolley is mounted on the guide rails and is capable of moving along the guide rails, a traveling hanging bracket is mounted on the trolley, and an anti-vibration pulley block and a circular-arc-shaped guide plate are arranged on the traveling hanging bracket; a storage rack is arranged on the mounting base; oscillating arm mechanisms are arranged on the two sides of the storage rack to form a slider-crank mechanism; during working, the oscillating arms are capable of oscillating out of the mounting base or within the mounting base along with the traveling hanging bracket in a linkage manner; the rotator towfish retracting / releasing device is further provided with a retracting / releasing winch; a towrope on the retracting / releasing winch bypasses the anti-vibration pulley block of the traveling hanging bracket and is connected with the rotator towfish. By adopting the structure and mechanisms, the traveling hanging bracket, the oscillating arm mechanisms, a stern line, the towrope, the storage rack and the retracting / releasing winch act together, the rotator towfish retracting / releasing device can complete the actions such as towfish retracting (releasing), towing, emerging out of water, centralizing, reversing and storing, and capable of smoothly realizing the towfish retracting / releasing, towing and storing functions.

Description

technical field [0001] The invention relates to the application field of a marine towing system, in particular to a revolving body towing fish retracting device. Background technique [0002] Usually, the A-frame, L-frame or knuckle-arm crane equipped on the support mother ship is used to implement the revolving body tow fish. This method has higher requirements on the support mother ship, especially the larger size and heavier weight. For towing fish, the mother ship is required to have special lifting equipment and sufficient lifting capacity. This kind of requirement can only be realized on special ships with large displacement or special design. In addition, the above-mentioned retractable equipment is generally required to be used under good sea conditions, which not only increases the use cost of towing equipment, but also greatly reduces Suitability of towing equipment. Contents of the invention [0003] The technical problem to be solved by the present invention ...
