Embodiment Construction
[0051] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0052] An embodiment of the invention provides a welding device. like figure 1 As shown, the welding device includes: a fixed barrel 1 shaped as a round tube; the lower end 102 of the fixed barrel 1 is connected with a straightening barrel 2 shaped like a round tube;
[0053] Wherein, the fixed bucket 1 has a plurality of first holes 3;
[0054] The upper end 201 of the righting bucket 2 has a second hole 4;
[0055] The lower end 202 of the righting bucket 2 has a plurality of third holes 5;
[0056] A plurality of fixing nuts 6 are welded on the outside of the fixing barrel 1 corresponding to the position of the first hole 3;
[0057] A plurality of centralizing nuts 7 are welded on the outside of the centralizing barrel 2 corres...

The invention discloses a welding device and belongs to the field of petroleum. The welding device comprises a circular tubular fixing barrel, wherein a circular tubular straightening barrel is weldedto the lower end of the fixing barrel; a plurality of first holes are formed in the fixing barrel; a second hole is formed in the upper end of the straightening barrel; a plurality of third holes areformed in the lower end of the straightening barrel; a plurality of fixing nuts are welded to the outer side of the fixing barrel and correspond to the positions of the first holes; a plurality of straightening nuts are welded to the outer side of the straightening barrel and correspond to the positions of the third holes; fixing screw rods being in screwed connection with the fixing nuts are arranged in the first holes; and straightening screw rods being in screwed connection with the straightening nuts are arranged in the third holes. According to the welding device disclosed by the invention, the fixing screw rods positioned on the fixing barrel are tightened, and then the straightening screw rods positioned on the straightening barrel below the fixing barrel are adjusted, thereby ensuring that to-be-welded oblique pipelines at upper and lower positions can correspond to each other, and the firmer and more convenient welding operation can be achieved.
Description
technical field [0001] The invention relates to the petroleum field, in particular to a welding device. Background technique [0002] With the rapid development of social economy, the demand for oil is gradually increasing. In oil field production, most of the pipelines located on the ground or underground are affected by geological factors, installation quality, pipeline tension, etc., and there is a phenomenon of breaking. In order to solve the problem of pipeline breakage, certain measures need to be taken. [0003] At present, the method adopted is to rectify the broken pipeline first, and then directly weld the broken pipeline. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] When the broken pipeline is corrected, the pipeline will be deflected, which makes the pipeline unable to be welded directly. Even if it is barely welded, the pipeline will be incorrectly posi...
