Ferromagnetic pressure vessel inner wall inspection system

The utility model provides a ferromagnetic pressure vessel inner wall inspection system. The ferromagnetic pressure vessel inner wall inspection system comprises a crawl device, a thickness measuringdevice, a remote controller, a camera device, a magnetic adsorption device and an encoder trolley. The crawler comprises a vehicle body, a controller, wheels and a power device. The camera device is installed on the vehicle body, can rotate by 360 degrees for camera shooting and is used for shooting video signals of the inner wall of the container. The encoder trolley is installed in the middle ofthe tail of the crawler and comprises a rotating wheel with an encoder. The wheels are Mecanum wheels and are symmetrically distributed on the two sides of the vehicle body, and omni-directional movement of the crawler is achieved. The thickness measuring device comprises a thickness measuring instrument and a probe, and the probe is installed on the encoder trolley to achieve synchronization ofposition encoding and thick
