Pipe modular prefabrication production line and pipe module prefabrication method

Abstract

The invention discloses a pipe modular prefabrication production line and a pipe module prefabrication method. The pipe modular prefabrication production line comprises straight pipe fixed-length cutting equipment, automatic groove processing equipment, pipe component assembling equipment, automatic welding equipment and transferring equipment, wherein the straight pipe fixed-length cutting equipment is used for cutting an original straight pipe according to the preset strength, so that a fixed-length straight pipe can be formed; the automatic groove processing equipment is used for processingthe fixed-length straight pipe, so that a groove can be formed in the end part of the fixed-length straight pipe; the pipe component assembling equipment is used for positioning pipe components to the end part, provided with the groove, of the straight pipe as well as performing the assembling and connecting operation; the automatic welding equipment is used for welding a junction position formedafter the straight pipe and the pipe components are assembled and connected, so that the pipe module assembling operation can be completed; and the transferring equipment is used for transferring thestraight pipe and the pipe components. The automation degree of the pipe modular prefabrication production line provided by the invention is high; the pipe module prefabrication efficiency can be improved; in the specific application process, the pipe modular prefabrication production line can adapt to the prefabrication of an oversized ultra-large-caliber pipe module; and the traditional oversized ultra-large-caliber pipe module construction status can be changed.

Description

technical field [0001] The invention relates to the field of pipeline assembly, in particular to a pipeline modular prefabrication production line and a method for prefabricating pipeline modules using the production line. Background technique [0002] Pipeline construction is indispensable in engineering buildings such as petrochemical energy offshore platforms. With the development trend of large-scale and intelligent engineering buildings, various engineering buildings have put forward higher requirements for pipeline construction, usually with high efficiency, low manufacturing cost, and process Safety is an important consideration standard for pipeline construction. In the process of pipeline construction, mechanical automation is the key to improving these standards. At present, in the construction of pipelines at home and abroad, the construction machinery of ordinary-caliber pipelines has a high degree of automation; but for super-large-sized pipelines (especially pi...

AI Technical Summary

Problems solved by technology

At present, in the construction of pipelines at home and abroad, the construction machinery of ordinary-caliber pipelines has a high degree of automation; but for super-large-sized pipelines (especially pipelines with a diameter exceeding 32 inches), due to factors such as weight, space size and construction safety, The mechanical equipment used for the construction of ordinary-caliber pipelines cannot be applied to the construction of super-large-diameter pipelines. Therefore, the construction of super-large-diameter pipelines is still in a state of manual work. According to statistics, in every project construction, super-sized The diameter of the pipe accounts for more than 30%

However, manual work has the following problems: the connection of each link is not tight, and the construction efficiency is low; when the welding groove between the straight pipe and the flange, tee, elbow and other pipe fittings is manually processed, it is difficult to ensure the groove angle and bluntness during the welding process. Uniformity of edges; low alignment accuracy between straight pipes and flanges, tees, elbows and other pipe fittings; when welding between straight pipes and flanges, tees, elbows and other pipe fittings, the welding material consumption is too much and the welding quality cannot be guaranteed
