Modular single-probe pipeline wall thickness detection robot

A modularized single-probe pipeline wall thickness detection robot comprises a driving device and a flexible measuring device, the driving device can move in the axial direction of a pipeline, and the flexible measuring device is connected with the driving device through a connecting bridge and is driven by the driving device to detect the wall thickness of the pipeline in the axial direction of the pipeline. The flexible measuring device is composed of an obstacle-crossing moving support which is movably connected with the connecting bridge and can elastically move up and down, and an ultrasonic wall thickness detecting probe connected to the lower portion of the obstacle-crossing moving support. The pipeline wall thickness detection device can be used for wall thickness detection of a single pipeline, can also be used for detection of a plurality of pipelines arranged side by side through simple splicing when a modular structure is adopted, and is high in efficiency and flexible to use.
