Cantilever type U-shaped steel pipe automatic material moving frame

The invention discloses a cantilever type U-shaped steel pipe automatic material moving frame, and belongs to the technical field of automatic material carrying. The automatic material moving frame comprises a series roller seat assembly, a moving frame, a gear rack, a three-in-one gear motor and a lifting air cylinder, the series roller seat assembly is fixed, a vehicle frame is driven by a gear rack pair to move in a longitudinal rectangular through groove formed by rollers of the roller seat assembly, the three-in-one gear motor and the lifting air cylinder are controlled, and therefore, a U-shaped steel pipe can be automatically moved from a water testing station to an arc detection sawing station. A vehicle frame joist cantilever extends out to transfer the U-shaped steel pipe to the arc detection sawing station, an auxiliary track does not need to be laid and disassembled when the specification of the U-shaped steel pipe is changed, transverse fixed-length movement of an arc detection table is not affec
