Kind Code:

A1

Abstract:

An automatic auxiliary workover rig, comprising a silo body (2) arranged on a skid-mounted baseplate (1.1), a guide-roller type elevator (7), a random-folding type traveling block rigid guide device (3), a truck-mounted folding type manipulator (4), a slip (8), a flatcar up-down adjustment device, a detection and conveying device (5) and a transfer device (6). The automatic auxiliary workover rig cooperates with an existing workover rig to complete ascending and descending of a tubing sucker rod during minor overhaul. The slip (8) is located above a wellhead blowout preventer and used for clamping and loosening a wellhead tubing. The silo body (2) is used for storing and outputting the tubing. The truck-mounted folding type tubing manipulator (4) garbs the tubing and then ascend and descend the tubing, meanwhile the manipulator is provided with a height adjusting device to realize flexible joint in tube thread fastening and unfastening. The elevator (7) lifts the tubing along the random-folding type traveling block rigid guide device (3), accuracy of the tubing track is improved, and the tubing is mounted and dismounted by using tube tongs. By means of the automatic auxiliary workover rig, automatic numerical control on existing oil extraction equipment is realized, pollution is low, efficiency is high, labor intensity of workers is lowered, and safety is improved.
