Description

Technical Field

[0001] The utility model relates to the technical field of pipeline robots, and more specifically to an anti-rollover device for pipeline robots. Background Art

[0002] A pipeline robot is an integrated system of machinery, electricity and instrumentation that can automatically walk along the inside or outside of a small pipeline, carry one or more sensors and operating machinery, and perform a series of pipeline operations. As for wheeled robots, this type of robot is widely used in pipeline inspection work, and many commercial robots are of this type.

[0003] However, when using a wheeled robot to move along a pipeline and perform maintenance tasks, there are no auxiliary guides on both sides. That is, when its moving route deviates, the robot itself deflects or even tilts relative to the pipeline, affecting its normal use. Therefore, we propose a pipeline robot anti-rollover device to solve the above problems. Utility Model Content
