Pipeline curvature detection device

The utility model discloses a pipeline curvature detection device, and belongs to optical detection equipment. Comprising a transmission mechanism and a scanning mechanism. The transmission mechanism comprises a plurality of rotating rollers which are linearly arranged at a preset distance, and the rotating rollers are at least in contact with two contact points on the peripheral surface of the to-be-detected pipeline and are suitable for driving the to-be-detected pipeline to move in the axial direction; the scanning mechanism comprises a portal frame arranged on the upper portion of the conveying mechanism and at least two laser scanning assemblies arranged on the upper portion of the portal frame and located on the two sides of the to-be-detected pipeline respectively. And the scanning surfaces of the two laser scanning assemblies at least cover the upper part of the peripheral surface of the to-be-detected pipeline. According to the utility model, the laser detection assembly is adopted as a measuring ele
