Iron roughneck lifting mechanism applied to oil field exploitation

The utility model discloses an iron roughneck lifting mechanism applied to oil field exploitation. The iron roughneck lifting mechanism comprises a base, a lifting arm and a horizontal conveying mechanism. The lifting arm is fixed to the base and comprises a lifting section and a drive section. A drive device is arranged in the drive section, and the lifting section is connected with a lifting connection piece in a sliding mode. After the drive device is started, a screw rod is driven to rotate, and the rotating screw rod is combined with a stud in a chelated mode to drive the lifting connection piece to move up and down. The lifting function is achieved by adopting the chelated mode, the design is ingenious, the structure is simple, operation is convenient, manufacturing cost is low, and the lifting effect is good. Meanwhile, an infrared distance measuring sensor is introduced to assist in lifting; on one hand, workers can visually master the specific lifting height and conveniently regulate the lifting height; on the other hand, quantified lifting is achieved, and the lifting precision is improved. The iron roughneck lifting mechanism has the advantages of being high in practicability and wide in application rang.
