Abstract
A movement-synchronized wellbore inspection system and a movement-synchronization control method thereof are disclosed. The wellbore inspection system comprises a rope-climbing robot, a wire rope, a ground wire rope moving device, a ground wire rope moving track, an underground wire rope moving device, an underground wire rope moving track, an inertial sensor and a control device. An upper end of the wire rope is connected to the ground wire rope moving device, and an lower end of the wire rope passes through the rope-climbing robot and is then connected to the underground wire rope moving device. The control device controls the underground and ground wire rope moving devices to move in synchronization, and then the inertial sensor carried on the rope-climbing robot detects posture data of the wire rope and transmits the data to the control device.
