Modularized small boat folding and unfolding device

Abstract

The invention provides a modularized small boat collecting and releasing device which is sequentially composed of a top collecting mechanism, a middle auxiliary positioning mechanism and a lower supporting base from top to bottom, a winch used for collecting and releasing the lower supporting base is installed on the top collecting mechanism, and the winch is provided with a plurality of steel wire ropes penetrating through the middle auxiliary positioning mechanism to be connected with the lower supporting base; the middle auxiliary positioning mechanism is provided with a floating body frame, a plurality of wave passing holes are formed in the side wall of the floating body frame, a plurality of buffering guide rollers are arranged along the inner wall of the floating body frame, and a plurality of longitudinal penetrating holes allowing steel wire ropes to penetrate through are formed in the floating body frame. At least two pairs of self-adaptive supporting bases are arranged on the lower supporting base, and a plurality of vertical positioning supporting columns are arranged on the side edge of the lower supporting base. The device has low requirements on ships, is suitable for various ships, is small in deck occupied area, does not need to be fixedly mounted, is flexible and convenient to store, is high in sea condition adaptability, and can stably and safely retract and release the boat under the condition of heavy storm waves.

Description

technical field [0001] The invention relates to supporting facilities for ships, in particular to a modular boat retractable device. Background technique [0002] The existing technology for retracting and deploying small boats mainly relies on special davits for the operation of retracting and deploying small boats at sea. Usually, special lifting davits are installed on the side of the boat, and the boats are released and recovered through the outboard of the davits. Releasing and recovering the small boat requires the crew to perform decoupling and hooking operations at sea, and the operation efficiency is low. It is even more difficult to operate in weather with strong winds and waves, and it is even impossible to carry out the operation of retracting and launching the boat at sea. [0003] In order to improve the retractable efficiency of the small boat, there is also a slideway-type smallboat retractable scheme, that is, a slideway is set at the stern, and the smallboa...

AI Technical Summary

Problems solved by technology

However, the cost of this solution is relatively high, and a large opening needs to be opened at the stern of the ship to make room for the installation and layout of the slideway. For some ships that cannot open at the stern, we can only think of other ways, and the...
