Hanging type small boat retracting and releasing device and method

Abstract

The invention relates to a hanging type small boat retracting and releasing device and method. The device comprises a suspension walking mechanism, a capturing mechanism, a steel cable winding and unwinding mechanism and recycling guide mechanisms, the suspension walking mechanism comprises a suspension arm, a crane and a walking drive, the suspension arm is fixed to the side of a mother ship, andthe walking drive drives the crane to walk along the suspension arm; the capturing mechanism comprises a bracket, a capturing rod and a capturing head, the bracket is a U-shaped frame body, the capturing rod is fixed to the inner side of the head of the bracket, and the capturing head is fixed to the outer side of the bow of a small boat and corresponds to the capturing rod; the steel cable winding and unwinding mechanism comprises a winding and unwinding winch, winding and unwinding pulley blocks and winding and unwinding steel cables, the winding and unwinding pulley blocks are multiple fixed pulleys and are installed on the crane corresponding to the lifting points of the bracket respectively, and the tail ends of a number of winding and unwinding steel cables bypass a number of fixedpulleys respectively; and the recycling guide mechanisms are radio receiving and releasing equipment, are respectively arranged at the height point of the small boat and the tail end of the suspensionarm and are used for signal interaction. Automatic releasing and retracting of the small boat are achieved, and the small boat is prevented from rotating and swinging.

Description

technical field [0001] The invention belongs to the technical field of automatic release and recovery of manned / unmanned small boats on board, and in particular relates to a lifting type small boat retracting device and method. Background technique [0002] At present, the hoisting type small boat retracting device configured on domestic active ships is mainly used for retracting and retracting manned small boats. When it is used for retracting and unmanned boats, the cooperation of the crew is required, that is, during the release and recovery process, the unmanned boats are on board. Both require a crew to cooperate with the attitude adjustment and release / hook operation of the unmanned boat during the release and recovery process. During the release process, the crew will return to the ship after completing the unhook / hook operation; for recovery needs, the personnel before the unmanned boat recovery must board the unmanned boat in advance, whether it is the release proce...

AI Technical Summary

Problems solved by technology

The hoisting type dinghy retractable devices of active ships mostly use hooks to realize the recovery / release of manned dinghy. When used for retracting unmanned boats, the original hook form cannot meet the needs of autonomous docking recovery / release, and new ones are needed. (2) How to prevent the rotation and swing of the unmanned boat during the recovery / release process

The existing hoisting type dinghy retractable devices mostly use wire ropes to hoist the dinghy. Due to the heavy weight of the unmanned boat itself, when the wire rope is used to hoist the dinghy, a single pendulum system is actually formed. Affected by the attitude change of the mother ship, the unmanned boat During the recovery / release process, it is inevitable that the effect of turning around itself or swinging will occur, which will bring safety risks to the equipment of the unmanned boat; (3) guide the unmanned boat in the recovery state to dock with the retractable device, so that the retractable The device has the ability to guide and recover unmanned boats
