Pipeline geometric size measuring machine

Abstract

The invention discloses a pipeline geometric size measuring machine and belongs to the technical field of measuring equipment. The pipeline geometric size measuring machine comprises a pipeline clamping device, a measuring device and a control box, and the pipeline clamping device, the measuring device and the control box are arranged on an operating platform. The pipeline clamping device is used for supporting a pipeline to be measured through a spindle box mechanism and a tail bracket mechanism. The measuring device is provided with two guide rails on the operating platform, the two guide rails are parallel to the axis of the pipeline clamping device, a measuring framework is driven by a measuring framework driving mechanism to move on the guide rails, and a vernier caliper clamp, an LVDT displacement meter clamp, a hatching pen clamp and a thickness gauge clamp are arranged on the measuring framework. When the pipeline geometric size measuring machine works, the position of the pipeline to be measured and the position of the measuring framework are adjusted electrically or manually, the geometric size of each portion of the pipeline to be measured is measured, or, marking-out is carried out. The pipeline geometric size measuring machine can complete the four operations of marking-out calibration of the pipeline, diameter measurement on any section, thickness measurement on any portion and ellipticity measurement on pipeline sections comprehensively. The pipeline geometric size measuring machine is high in working reliability and convenient to operate, and can improve locating accuracy, enhance measuring effects and improve work efficiency.

Description

technical field [0001] The invention relates to a measuring machine for pipeline geometric dimensions, which belongs to the technical field of measuring equipment. Background technique [0002] In order to determine the ultimate bearing capacity of the pipeline, it is necessary to know the actual geometric dimensions of different positions of the pipeline, such as arbitrary cross-sectional diameter and ellipticity, wall thickness at any position, etc. At present, these measurements are done independently with corresponding instruments, and there is no unified measurement platform, which is not only inefficient, but also unable to accurately locate and lack a benchmark for the analysis of measurement results, which restricts buried pipelines in permafrost areas or deep-water submarine pipelines. Failure mode and damage mechanism research under complex loads. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention p...
