Embodiment Construction
[0035] Figure 1 to Figure 7 As shown, a construction device for small-diameter pipeline maintenance integrated construction, including: a fixed frame 1, the main frame of the fixed frame 1 is roughly C-shaped, and there are a pair of V-shaped blocks on the left and right, and the V-shaped blocks are divided into V-shaped blocks. The upper block 103 of the shape block and the lower block 104 of the V-shaped block are screwed between the upper block 103 of the V-shaped block and the main body of the fixed frame 1, and the top of the upper block 103 of the V-shaped block is a rotary handle 102, which can be adjusted by turning the rotary handle 102. The vertical position of the upper block 103 is to clamp the original pipeline 9; the lower block 104 of the V-shaped block is fixedly connected with the main body of the fixed frame 1; the left and right parts of the fixed frame 1 are connected by two cylindrical beams 105; the fixed frame 1. The upper part is a standpipe 101, the u...

The invention belongs to the field of pipeline maintenance engineering, and in particular relates to a construction device and construction method for integrated construction of small-diameter pipeline maintenance, which is mainly used for on-site maintenance of small-diameter pipelines, and can realize pipeline alignment and groove cutting , Integrated construction of automatic welding. The device includes: fixed frame, vertical support frame, growth joint, lifting joint, slips, split beveling machine and open automatic welding machine. The invention uses V-shaped blocks to fix the pipeline, uses chains to fix and replace pipe sections, and multi-segment splicing to form an integral beam. The design can adapt to different pipe diameters and pipe span widths, and solves the problem that existing products cannot be used for on-site maintenance and construction parts of small-diameter pipes. Independence, construction accuracy and low efficiency. By virtue of the advantages of existing products, the invention realizes its function integration, novel and compact structure, improves engineering efficiency, and has practical value.
Description
technical field [0001] The invention belongs to the field of pipeline maintenance engineering, and in particular relates to a construction device and construction method for small-diameter pipeline maintenance integrated construction, which are used for bevel cutting, centering assembly and welding of small-diameter pipelines. Background technique [0002] Due to the influence of environment, load and other factors, pipelines are prone to damage, and damaged pipe sections need to be replaced and repaired. Welding technology is currently the most mature repair method. However, the manual welding process is difficult to guarantee, so the welding is gradually automated. In order to cut and weld the bevel at any position of the pipeline, the split beveling machine and the open automatic welding machine came into being. Existing maintenance tools are mostly used in large-diameter pipelines, and nearly 80% of the pipelines in the oil field are small-diameter pipelines with a diame...
