Multi-channel small-diameter digital real-time imaging detection device

The invention discloses a multi-channel small-diameter digital real-time imaging detection device, which comprises: a driven jacking roller, a fixed frame, a jacking cylinder, a driving roller wheel group, a driven dynamic pressure wheel group and a pressing part cylinder, wherein the driven jacking roller is arranged on a conveying line and is arranged at equal intervals with the driving roller wheel group; the jacking cylinder is arranged on the fixed frame; the driving roller wheel group is arranged on the jacking cylinder; the pressing part cylinder is arranged on the fixed frame; the driven dynamic pressure wheel group is arranged on the pressing part cylinder. A plurality of small-diameter rod (pipe) pieces are supported and driven to rotate by means of the driving roller wheel group, and downward pressure is provided from the driven dynamic pressure wheel group to increase frictional force generated during rotation. The device fundamentally solves various defects of the traditional manual rotation of t
