Description

Carrying structure and folding and unfolding method of work boat

Technical Field

The invention relates to a carrying structure and a folding and unfolding method of a work boat.

Background

In inland rivers, hubbes and sheltered navigation areas, official law enforcement ships, engineering ships or transport ships and the like are used, and work boats are usually carried on the official law enforcement ships, engineering ships or transport ships and the like. At present, the modes of carrying a working boat on a mother ship mainly include a flapping towing method, a crane folding and unfolding method and a stern slideway carrying and folding and unfolding method. Firstly, the shooting and towing method is the simplest method, is commonly used in a Yangtze river basin, is used for simply binding and fastening a working boat on the side of a mother ship, is towed by the mother ship to sail, and can release the working boat by directly loosening the bound cable when the working boat needs to be used; secondly, a crane retraction method is that a hoisting machine is installed on the side surface of a ship, a working boat is arranged on a mother ship through a boat frame, the working boat is hoisted out of the water surface or retracted to the mother ship through the hoisting machine, however, when the working boat is hoisted through the hoisting machine, a series of manual operations such as starting the hoisting machine, mooring rope fastening the working boat, assisting in traction command and the like are needed in the process of retraction or retraction, the consumed time is more, and in the process of retraction, personnel on the working boat get on or off the ship along with the hoisted working boat, certain potential safety hazards exist, and emergency tasks are not easy to execute; finally, the stern slide carrying and storing method is fast in boat storing and storing, but the slide equipment is expensive, the design and the structural process of the slide are complex, the construction cost is high, the stern slide carrying and storing method is generally used under high sea conditions, and in the operation process, operations such as centering, capturing and limiting of the boat also need special training, and the boat storing and storing method has high requirements on the operation of a driver. In addition, the work boat all has independent propulsion system, and above several kinds of modes of carrying the work boat, in mother's ship navigation in-process, the host computer of work boat is idle, can not help mother's ship to impel with higher speed.

Disclosure of Invention
