Abstract

The invention provides an annular alignment device and a rapid alignment method for coaxial butt joint of steel pipes, and belongs to the technical field of steel pipe butt joint. The annular alignment device comprises an annular fixing piece and a plurality of adjusting mechanisms, wherein the annular fixing piece is used for being arranged on a steel pipe needing to be aligned in a sleeving mode; and the plurality of adjusting mechanisms are evenly arranged in the circumferential direction of the annular fixing piece, and the adjusting mechanisms can move in the radial direction of the annular fixing piece so as to clamp the steel pipes needing to be aligned. According to the annular alignment device and the rapid alignment method for coaxial butt joint of the steel pipes, it can be guaranteed that alignment and adjustment of annular opening welding seams can be rapidly and conveniently completed in a narrow operation space or on a relatively small operation structure, the welding quality is fully guaranteed, meanwhile, the mechanical cost and the labor cost are saved, and meanwhile, the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of butt jointing of steel pipes, and in particular relates to an annular alignment device for aligning butt joints of weld seams of steel pipes and a quick alignment method for coaxial butt joints of steel pipes. Background technique [0002] In the current infrastructure and other fields, the application of steel pipe structures is very common and diverse. During the construction process, the overall splicing and butt joint of steel pipes are often limited by the narrow space or insufficient auxiliary resources, resulting in two sections of steel pipes that need to be spliced ​​and welded. The completion of the welded butt joint. [0003] Therefore, in this process, it is necessary to comprehensively consider the use of cranes, chain hoists or other large-scale auxiliary measures to complete the butt joints of the steel pipe welds according to whether the steel pipes are butt jointed in the pipe trench or i...
