Embodiment Construction

[0034] Figure 1 to Figure 6 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 pipeline; 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 upper part of the fixed frame 1 It is a standpipe 101, the upper h...

Abstract

The invention belongs to the field of pipeline maintenance engineering, and particularly relates to a construction device and method for integrated construction of small-diameter pipeline maintenance.The construction device and method are mainly applied to site maintenance of small-diameter pipelines, and integrated construction of pipeline centering and pairing, groove cutting and automatic welding can be achieved. The device comprises a fixing frame, a vertical supporting frame, an extension section, a lifting section, a slip, a split beveling machine and an open type automatic welding machine. According to the construction device and method, the design that a pipeline is clamped and fixed through a V-shaped block, a replacement pipe section is fixed through a chain, and a plurality ofsections are spliced into an integral beam is adopted, so that the construction device and method can adapt to different pipe diameters and pipe span widths, and the problems that an existing productcannot be suitable for site maintenance of small-diameter pipelines, construction components are independent, and the construction precision and efficiency are low are solved. By means of the advantages of the existing product, function integration of the existing product is achieved, the structure is novel and compact, the engineering efficiency is improved, and the practical value of the construction device is achieved.

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...
