Method for lifting and carrying overweight hull section by utilizing combination tool of hinge and heeling-preventing support

Abstract

The invention provides a method for lifting and carrying an overweight hull section by utilizing a combination tool of a hinge and a heeling-preventing support, comprising the following steps of: (1) preparing before lifting and carrying a hull section; (2) lifting and rotating the hull section; and (3) arranging a support frame and a jack, measuring and correcting. The invention has the beneficial effects that an overweight hull carried by a slipway is divided under the condition that the capacity of hoisting equipment is limited, a measure that a special combination tool of the hinge and the heeling-preventing support is coordinated with a crane is adopted, and an expected effect can be achieved. The combination tool overall has simple structure, less parts are used, the combination tool is easy to manufacture, assemble and connect, the cost is low, the combination tool is easy to operate, and the operation is easy to grasp. An experience is accumulated for field mounting of the overweight hull section carried by the shipway, technical support is obtained, the problem that a large-scale overweight hull section is difficult to lift is solved, lifting is completed in one step, and both the success rate and the safety in the lifting process are strongly guaranteed.

Description

technical field [0001] The invention relates to a hoisting method in shipbuilding production in a shipyard, in particular to a segmented hoisting method for carrying an overweight hull by using a combined tool of a hinge and an anti-heeling bracket. Background technique [0002] At present, the shipbuilding industry at home and abroad is developing rapidly, and the relative competitiveness among enterprises is also very large. High quality and short construction period are the magic weapons of enterprises. Therefore, the size and weight of the hull sections are increasing and increasing, and the purpose is to reduce the hull sections. Quantity, shorten the loading cycle of the berth, and deliver the ship on time or in advance, so that the competitiveness of the company can be further improved, and more new shipbuilding orders can be accepted. [0003] However, for some old factories or small and medium-sized shipyards, due to the limitation of the site and the capacity of li...
