description An automatic auxiliary workover rig includes a silo body arranged on a skid-mounted baseplate, a guide-roller type elevator, a random-folding type traveling block rigid guide device, a truck-mounted folding type manipulator, a slip, a flatcar up-down adjustment device, a detecting and conveying device, and a transfer device. The automatic auxiliary workover rig cooperates with an existing workover rig to complete ascending and descending of a sucker rod of an oil pipe during minor overhaul. The slip is located above a wellhead blowout preventer, and is configured to clamp and loosen the oil pipe of a wellhead. The silo body is configured to store and output the oil pipe. The truck-mounted folding type oil pipe manipulator garbs the oil pipe and then ascend and descend the oil pipe, meanwhile the manipulator is equipped with a height adjusting device to realize flexible joint in tube thread fastening and unfastening.
