This invention discloses a non-standard drill pipe loading and unloading jig. It utilizes a clearance notch to avoid the protruding ribs on the drill pipe section surface. The upper surface of the support plate vertically abuts against the drill pipe section, providing support. Compared to using friction generated by clamping to resist the weight of the drill pipe section, this method avoids damage and is well-suited for loading and unloading large drill pipe sections.
