Description

Technical Field

[0001] The present invention relates to the technical field of pipeline production, and particularly to a layout structure of a prefabricated pipeline production line. Background Art

[0002] For a long time, pipeline prefabrication work has mainly been carried out on-site. All processing work on the pipeline, such as scribing, cutting, beveling, assembly, welding, non-destructive testing, anti-corrosion pressure testing, etc., is completed at the installation site. This method not only makes the construction period longer, the quality difficult to unify, and labor-intensive, but also generates more construction waste and greater noise pollution at the site, causing great interference to the normal life of surrounding residents.

[0003] With the rapid development of China's economic construction, the scale of engineering construction projects is becoming increasingly large-scale, skid-mounted, and integrated, and the workload of pipeline construction is increasing. In order to improve production efficiency, reduce construction costs, and reduce material losses, pipeline prefabrication production lines are very important.

[0004] The layout of the pipeline prefabrication production line is an important part of pipeline prefabrication production. If the layout is unreasonable, it will not only waste production space, but also affect the production efficiency of the enterprise, and it will be difficult to modify the layout of the production line in the later stage.

[0005] Since pipelines of different materials or different thicknesses need to be thermally cut or cold cut according to their own situations, but often only one cutting method can be completed in one production line, and each production workshop is independent of each other, the layout of the production line is not reasonable enough, resulting in a certain degree of waste of resources.

[0031] In one embodiment, the pressure test area 2, the cold cutting treatment area, and the first welding area 7 are separated by a wall. The flaw detection area 4 is located in the area corresponding to the end of the first track 1, so that the pressure test area 2, the cold cutting treatment area, and the first welding area 7 each form an independent area, avoiding mutual influence among the areas during the processing. The first track 1 is not in communication with the flaw detection area 4. The flaw detection area 4 is a closed space to avoid the radiation generated from affecting the human body.

[0032] In one embodiment, the first welding area 3 is divided into two half-areas by the first track 1. One of the half-areas includes a plurality of first welding work stations, and the other half-area is set as a first post-welding buffer and inspection area, separating the first welding work stations from the first post-welding buffer and inspection area to avoid affecting the pipes and the staff in the buffer and inspection area during welding. The plurality of welding work stations include pressing arm type welding work stations and cantilever type welding work stations, and can perform manual, semi-automatic, and full-automatic welding operations, and adopt a suitable welding method according to the actual situation to meet the diversity of production.

[0033] In one embodiment, the second welding area 7 is divided into two half areas by the second track 5. One half area includes a plurality of second welding stations, and the other half area is set as the second post-welding buffer and inspection area. The second welding area is also equipped with a transfer logistics for sending the welded pipes to the flaw detection area. The first welding station is separated from the first post-welding buffer and inspection area to avoid affecting the pipes and workers in the buffer and inspection area during welding. The plurality of welding stations include a press arm type welding station and a cantilever type welding station, which can perform manual, semi-automatic and full-automatic welding operations. Appropriate welding methods are adopted according to the actual situation to meet the diversity of production.

Since the second welding area 7 and the flaw detection area 4 are located in the upper half-span area and the lower half-span area respectively, and both the welding area 7 and the flaw detection area 4 are located at the end of the production line, the welded pipes can be more conveniently transported into the flaw detection area 4 by a transfer trolley, improving the efficiency of the logistics in the production line.

[0034] In one embodiment, the first track 1 is parallel to the second track 5. A first traveling crane 17 perpendicular to the direction of the first track 1 is arranged in the upper half-span area. A second traveling crane 18 perpendicular to the direction of the second track 5 is arranged in the lower half-span area. A plurality of ground tracks and lifting traveling cranes are arranged vertically and horizontally in the prefabricated pipe production line, facilitating the transfer of pipes between various workstations and improving the processing efficiency of the production line.

[0035] In one embodiment, both the assembly platform 6 and the assembly area 9 complete the final assembly operation of the pipes.

[0036] In one embodiment, the assembly platform 6 is divided into two areas by the second track 5. The area close to the upper half-span area can be divided into a post-welding treatment area, which includes a weld heat treatment area and a rust removal and anti-corrosion area. The weld heat treatment area is an area for heat-treating the pipes to eliminate welding residual stress.

The welded pipes are sequentially subjected to heat treatment and rust removal and anti-corrosion. The post-welding treatment area is connected to the pressure test area 2, with a reasonable layout, saving transfer time and improving processing efficiency.

[0037] In one embodiment, safety channels are arranged in both the upper half-span area and the lower half-span area, ensuring that operators can quickly evacuate in case of an emergency.
