The utility model relates to a straightness detection mechanism for self-service drill pipes, comprising a frame plate. A plurality of contact induction devices, supporting devices and material discharging devices are symmetrically arranged on the upper surface of the frame plate. The front side of the frame plate is fixedly connected with material guide plates, material moving devices and a storage and access rack. The contact induction devices are distributed on the frame plate in an evenly-spaced way. The supporting devices and the material discharging devices are respectively and symmetrically arranged at the two ends of the upper surface of the frame plate in the length direction, and the material discharging devices are disposed between the two supporting devices. The self-service drill pipe straightness detection mechanism is relatively simple in structure, detects the straightness of a drill pipe in a multi-point detection mode, and has the characteristics of high accuracy and reliable detection. A hydraulic rod automatic adjusting structure is arranged, a drill pipe can be accessed without manual operation, and a single drill pipe can be automatically accessed.
