Manufacturing and assembling method for large closed cold accumulation tank

Abstract

The invention discloses a manufacturing and assembling method for a large closed cold accumulation tank. The manufacturing and assembling method comprises the following steps that S1, a steel plate ofa tank body of the cold accumulation tank is subjected to scribing and blanking based on the BIM technology; S2, welding grooves in the four edges of the steel plate are machined and detected; S3, the steel plate is rolled and welded into a cold accumulation tank shell ring prefabricated part; S4, all shell rings are hoisted, aligned and then fixed in a spot welding mode, and the adjacent shell rings are symmetrically welded into a cylinder body; and S5, a left end socket and a right end socket of the cold accumulation tank are welded to the cylinder body, cold accumulation tank accessories are welded, and manufacturing and assembling of the cold accumulation tank are completed. According to the manufacturing and assembling method, the scheme that the cold accumulation tank is manufactured through on-site welding and assembling is adopted, transportation of large equipment is converted into transportation of small components, the difficulty that the site space is limited during installation is effectively overcome soon, and the risk possibly generated in the transportation process and the influence possibly generated on the surrounding environment and the society in the transportation process are reduced.

Description

technical field [0001] The invention is applied to the manufacture of cold storage tanks, in particular to a method for manufacturing and assembling large-scale closed cold storage tanks. Background technique [0002] During the installation process of large-scale industrial equipment, especially involving large-scale group buildings, the central heating and cooling consumption is particularly large, and the equipment used is also large-scale equipment. The purchase and transportation costs of equipment are high, and the site space for installation is limited. limited, the installation volume is relatively large. The general traditional method is to use factory prefabrication and transport it to the project for installation. The transportation of equipment has high requirements on the technical strength of the carrier and vehicles. The transportation of objects on the road is likely to cause uneasiness to surrounding vehicles, and unreasonable organization will affect traff...

[0002] During the installation process of large-scale industrial equipment, especially involving large-scale group buildings, the central heating and cooling consumption is particularly large, and the equipment used is also large-scale equipment. The purchase and transportation costs of equipment are high, and the site space for installation is limited. limited, the installation work is relatively large

The general traditional method is to use factory prefabrication and transport it to the project for installation. The transportation of equipment has high requirements on the technical strength of the carrier and vehicles. The transportation of objects on the road is likely to cause uneasiness to surrounding vehicles, and unreasonable organization will affect traffic safety, and the social and economic benefits are poor
