Carrying structure and folding and unfolding method of work boat

Abstract

The invention discloses a carrying structure and a folding and unfolding method of a work boat. The work boat is tied and fixed to the stern of the mother boat through cooperation of the catching buckles and the catching sleeve rods, and due to the fact that the work boat and the mother boat are effectively and mechanically connected in a limiting mode through the catching buckles and the catchingsleeve rods and can be reliably fixed to the designated position, the work boat has high safety and controllability and has the advantages of being safe, simple and convenient to use in the folding and unfolding process. The structure is simple, and the cost is low. Besides, the working boat is arranged at the stern of the mother ship, so that when the mother ship needs to be accelerated, the work boat can be started to assist in accelerating the mother ship.

Description

technical field [0001] The invention relates to a carrying structure and a retracting method of a working boat. Background technique [0002] Use public law enforcement ships, engineering ships or transport ships in inland rivers, lakes and sheltered navigation areas, and usually carry working boats on them. At present, the methods of carrying the working boat on the mother ship mainly include the dragging method, the crane retracting method, and the stern slide carrying and retracting method. First of all, the dragging method is the simplest method, which is often used in the Pearl River Basin. The working boat is simply tied and fastened to the side of the mother ship, and the mother ship drags it to sail. When the working boat needs to be used, the binding is directly released. However, the working boat is fastened to both sides of the mother ship, and the fluid impact force received by the working boat during the voyage is relatively large, causing the working boat to b...

AI Technical Summary

Problems solved by technology

First of all, the dragging method is the simplest method, which is often used in the Pearl River Basin. The working boat is simply tied and fastened to the side of the mother ship, and the mother ship drags it to sail. When the working boat needs to be used, the binding is directly released. However, the working boat is fastened to both sides of the mother ship, and the fluid impact force received by the working boat during the voyage is relatively large, causing the working boat to be unstable. With the increase of ships, the working boats on both sides of the mother ship are likely to affect the navigation of other ships, and there is a greater risk of scratching; secondly, the crane retracting method is to install lifting machinery on the side of the ship, and arrange the working boats through the boat frame. On the mother ship, after the working boat is hoisted by the hoisting machine, the working boat is hoisted to the water surface or retracted to the mother ship. A series of manual operations such as machinery, cable-secured workboats, and auxiliary traction command consume a lot of time, and during the hoisting process, there is a certain degree of safety for the personnel on the workboat to board or launch the hoisted workboat. Hidden dangers are not conducive to the implementation of emergency tasks; finally, the stern slideway is equipped with a retractable working boat that is relatively fast, but the slideway equipment is relatively expensive, the design and structure of the slideway itself are relatively complicated, and the construction cost is relatively high. The stern slide carrying and retracting method will only be used in high sea conditions, and in the operation process, the centering, capturing, and limiting operations of the working boat also require special training, which has high requirements for the driver's operation

In addition, the working boat has an independent propulsion system. The above methods of carrying the working boat will not help the mother ship to propel and accelerate when the main engine of the working boat is idle during the sailing process of the mother ship.
