Zusammenfassung: | The utility model relates to the technical field of oil production engineering, in particular to a hydraulic clamp rotating operation control device. The hydraulic clamp rotating operation control device comprises a safety door, a stay wire and a hydraulic reversing valve. The safety door is arranged at the end of the hydraulic tong head, the right end of the safety door is rotatably connected with the safety door fixing seat, the safety door is connected with the stay wire through the stay wire connecting frame, the stay wire is limited by the first stay wire limiting frame and the second stay wire limiting frame, and one end of the stay wire is connected with the hydraulic reversing valve. According to the hydraulic clamp rotating operation control device, the working state of the hydraulic clamp is controlled through the closing state of the safety door, the closing state of the safety door is transmitted to the hydraulic reversing valve through the stay wire, and the hydraulic reversing valve controls the |
