The invention discloses a pipeline robot comprehensive test device, which comprises a pipeline assembly, a sensor assembly and a medium supply assembly. The pipeline assembly comprises a circumferential weld test pipeline, and the circumferential weld test pipeline is provided with at least one bulge surrounding along the circumferential direction; the sensor assembly is used for detecting vibration of the circumferential weld test pipeline and detecting the moving speed of a pipe cleaner; the pipeline assembly is of a closed structure and allows the pipe cleaner to move circularly; and the medium supply assembly is used for providing power for movement of the pipe cleaner. According to the pipeline robot comprehensive test device, the pipeline assembly is arranged and comprises the circumferential weld test pipeline, the influence of the circumferential weld test pipeline on movement of the pipeline cleaner is analyzed through cyclic movement of the pipeline cleaner in the pipeline assembly, accurate experimental data are obtained through the sensor assembly, and therefore, the influence of the pipeline with the circumferential weld on the pipe cleaner in actual use can be effectively guided.
Description
technical field [0001] The invention relates to the field of pipeline detection, in particular to a pipeline robot comprehensive testing device. Background technique [0002] The pipeline pig PIG is a kind of testing equipment that travels with the medium in the running oil and gas pipeline. The pipeline pig is used for non-destructive testing mainly for thickness measurement (the thickness of the pipeline will be lost after corrosion) and crack inspection. The principle of Ultrasonic Intelligent Pig (Ultrasonic Intellignet Pig) is: when the ultrasonic pulse sent from the probe meets the surface of the pipe wall, an echo is generated, and when it encounters the bottom of the pipe wall, another echo is generated, and the first and second The wall thickness value can be obtained by dividing the interval time of the two echoes by the known sound velocity. Based on the analysis of the echoed signal, this method can also detect cracks in the pipe. [0003] However, the current ...
