Pipeline guiding mechanism of pipeline detection machine

The utility model relates to the technical field of pipeline detection machines, in particular to a pipeline guiding mechanism of a pipeline detection machine, which comprises a base, a U-shaped block is fixedly connected to the left end of the base, a supporting plate is fixedly connected to the right end of the base, and a cleaning assembly used for cleaning the surface of a pipeline is arranged in the middle of the base. The pipeline cleaning device comprises a U-shaped block, a containing groove is formed in the lower end of the U-shaped block, a clamping assembly used for clamping a pipeline is arranged at the upper end of the U-shaped block, the lower end of the clamping assembly is connected with a clamping block, and a containing groove is formed in the lower end of the clamping block. Dust and impurities on the surface of a detected pipeline can be cleaned up before detection, the detection effect is prevented from being affected, the pipeline can be clamped and fixed through the clamping assembly, d
