Problems solved by technology

[0002] Pipeline deformation is a common problem in the process of large-scale equipment inspection and testing, especially in coastal areas, where foundation subsidence often occurs. When the pipeline is deformed, it will have a great impact on the safety of the pipeline, which will cause stress concentration and easily reduce the strength. Defects will occur, and in serious cases, it will cause leakage at the weak position of the welded joint, causing serious safety accidents
And when the pipeline deforms, stress analysis needs to be carried out according to the requirements of the regulations. At this time, the deformation of the pipeline needs to be measured. At present, there is no suitable and convenient pipeline measurement device

Abstract

The invention relates to the technical field of pipeline measurement, and discloses a deformation measuring device and method which can quickly detect whether a pipeline deforms or not. The deformation measuring device comprises a strip-shaped belt body, a connecting piece and laser assemblies; the connecting piece is fixedly connected with one end of the strip-shaped belt body; the connecting piece is detachably connected with the other end of the strip-shaped belt body; and the laser assemblies are detachably connected with the strip-shaped belt body and are evenly distributed in the extending direction of the strip-shaped belt body. According to the deformation measuring device and method of the invention, the strip-shaped belt body and the connecting piece are utilized, so that annularstructures with different sizes can be formed and can be wound on the outer wall of a to-be-detected pipeline; the plurality of laser assemblies are sequentially fixed on the strip-shaped belt body;the strip-shaped belt body can be adjusted, so that an annular surface formed by the plurality of laser assemblies and a cross section where the measurement position of the to-be-measured pipeline islocated can be kept on the same plane, and therefore, the accuracy of the measurement result of the deformation of the pipeline can be improved, meanwhile, the device is convenient to carry and assemble by an operator, and portability and detection efficiency are improved.
