During production, multiple indicators need to be tested to ensure pipeline safety and performance.

[0003] At present, when testing different index parameters of existing municipal pipelines, different detection devices are often needed to detect municipal pipelines. For example, when testing the inner and outer surfaces of the pipeline, whether there is crack damage on the pipeline surface, pipeline robots with different structures are generally required to detect the inner and outer surfaces of the pipeline. The required detection cost is high, and the existing detection device has a relatively single function and can only detect a certain indicator.

The outer wall of the outer arc plate 41 is fixedly connected with a connecting plate 43. An outer walking wheel 45 is arranged on the side of the connecting plate 43 away from the connecting plate 43. A locking ring 44 is movably connected between the outer walking wheel 45 and the connecting plate 43. The outer walking wheel 45 can be rotated and adjusted, and then the outer walking wheel 45 is fixed by the locking ring 44, so that the outer walking wheel 45 can only walk along the outer wall of the pipeline. It should be noted that the outer traveling wheel 45 is a general universal wheel structure, which is a prior art. A second driving motor 46 is arranged on the outer side of the outer traveling wheel 45 to drive the outer traveling wheel 45 to rotate.
