On-site manufacturing and mounting method and manufacturing and mounting equipment for ultra-large cylinder

Abstract

The invention provides an on-site manufacturing and mounting method and manufacturing and mounting equipment for an ultra-large cylinder, and the method comprises the steps: manufacturing a ground support: the ground support comprises a mounting part and a manufacturing part, and the mounting part is provided with a guide rail; the turnover frame is in an L shape formed by a manufacturing supporting frame and a mounting supporting frame, an arc-shaped tool is arranged on the front face of the mounting supporting frame, and an arc-shaped supporting plate is arranged at the inflection point of the back face of the turnover frame; manufacturing a cylinder body: manufacturing a support frame to be horizontal, matching a support plate with a guide rail, and manufacturing the cylinder body on the support frame; the manufacturing supporting frame is pushed to rotate towards the mounting part, and the supporting plate rolls along the guide rail until the supporting legs of the mounting supporting frame are supported by the mounting part; and mounting the cylinder. According to the invention, the investment of on-site construction equipment, especially hoisting equipment, is greatly saved, and the cost is greatly reduced; the bearing of each lifting point of the component is greatly reduced, the number of internal supporting frames is greatly reduced, the deformation of the cylinder body is controllable, and the safety and the stability are greatly enhanced compared with a conventional turning process.

Description

technical field [0001] The invention relates to the technical field of ultra-large container construction, in particular to an on-site fabrication and installation method and fabrication and installation equipment for an ultra-large cylinder. Background technique [0002] A certain type of large-scale steel non-standard cylinder has an external dimension of up to φ34m, and the maximum process section weighs about 600t. Due to problems in the transportation of super-large and overweight horizontal container steel structure components, it is necessary to complete the manufacturing and installation at the construction site. The conventional manufacturing process of this kind of steel structure parts, especially pressure vessel parts, is vertical manufacturing and horizontal installation, that is, the axial direction is vertical during manufacture, and the axial direction is horizontal during installation. The vertical 90-degree displacement, the conventional operation plan is d...

Problems solved by technology

These overturning methods add a lot of additional stress to the components during the overturning process, which is not good for the structural safety of the components.

In addition, since the ratio of the thickness of the cylinder to its external diameter is very small, the cylinder is easily deformed if the force is uneven during the hoisting process, affecting product quality and increasing risks
