Problems solved by technology

[0002] Large-scale towers in the cold box are generally docked with blocks and cranes. This docking method is very expensive and takes a lot of time for docking. At the same time, the quality of tower docking cannot be guaranteed, which often leads to tower failures. The variables are unqualified, or the column itself is tilted. In order to reduce the cost of column docking and reduce the time consumed by docking, it is necessary to design a new method of docking alignment and matching top tools for this method. of

Abstract

The invention relates to a large tower butt joint aligning method and matched ejecting tools. Firstly, an upper end tower is stacked on a lower end tower. The upper end tower is hoisted through a crane. The position of a pipe opening of the upper end tower and the position of a pipe opening of the lower end tower are observed, it is ensured that 0-degree lines between the two towers can coincide, and the distance between butt joint openings of the upper end tower and the lower end tower ranges from 10 mm to 12 mm. Then, the butt joint unfitness between the upper end tower and the lower end tower is observed and needs to be smaller than 15% of the wall thickness. The butt joint unfitness between the upper end tower and the lower end tower is controlled through a jack and the first ejecting tool. The perpendicularity between the upper end tower and the lower end tower is controlled through the jack and the second ejecting tool. The large tower butt joint aligning method and the matched ejecting tools have the beneficial effects that the structure is simple, using is convenient, the manufacturing cost is low, the butt joint time of the towers can be greatly saved during using, and therefore the butt joint cost of the towers is reduced.

Description

technical field [0001] The invention relates to the technical field of butt jointing of large towers, in particular to a method for butt jointing and alignment of large towers and matching top tools. Background technique [0002] Large-scale towers in the cold box are generally docked with blocks and cranes. This docking method is very expensive and takes a lot of time for docking. At the same time, the quality of tower docking cannot be guaranteed, which often leads to tower failures. The variables are unqualified, or the column itself is tilted. In order to reduce the cost of column docking and reduce the time consumed by docking, it is necessary to design a new method of docking alignment and matching top tools for this method. of. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for docking and aligning large-scale towers and a matching top tool, which has the advantages of simple structure, convenie...
