Method for installing tank body in ship body

Abstract

The invention discloses a method for installing a tank body in a ship body. The method comprises the following steps of: establishing a first reference plane and a second reference plane, calculatinga relative difference value delta Hi '= delta H1i-delta H<imin>, and setting the thickness S of a cushion block for supporting each second supporting point to be equal to delta Hi' + s1; establishinga third reference plane and a fourth reference plane, calculating a relative difference delta H'i'= delta H' < 1i >-delta H '< imin >, and setting the thickness S' of a temporary supporting seat for supporting each fourth supporting point to be delta H '' + s' < 1 >; mounting each temporary supporting seat with a corresponding thickness, hoisting the tank body and lowering the tank body to the temporary supporting seat, enabling the second supporting point on the tank body to correspond to the first supporting point on the ship body and enabling the fourth supporting point to correspond to the third supporting point when the tank body is lowered, measuring the required cushion block thicknesses between the first supporting point and the corresponding second supporting point, and installing cushion blocks with the corresponding thicknesses; and removing the temporary supporting seat, and lowering the tank body to a ship body. The installation method is accurate in positioning, errors caused during installation can be reduced in the mode that the temporary supporting base is arranged first and then the actual cushion block thickness is measured, and the installation precision ishigh.

Description

technical field [0001] The invention is used in the technical field of tank body hoisting, and in particular relates to a method for installing a tank body in a ship hull. Background technique [0002] The sealed container used to store liquid or gas is the storage tank. The storage tank project is an indispensable and important infrastructure in industries such as petroleum, chemical industry, grain and oil, food, fire protection, transportation, metallurgy, and national defense. At present, more and more Most industries and enterprises have applied storage tanks. For example, asphalt tanks are widely used in the field of engineering and construction. The asphalt tanks are located in the asphalt concrete mixing system and used for heating and blending with heat transfer oil, which is the key to reducing investment costs and improving the economic benefits of equipment. Usually need to transport hoisting. [0003] At present, the hoisting and installation process of large ...

AI Technical Summary

Problems solved by technology

[0003] At present, the hoisting and installation process of large asphalt tanks in the domestic shipbuilding industry is limited by the hoisting capacity and the level of measurement technology. Phenomena such as low precision and inaccurate positioning
