Abstract

The invention discloses an offshore platform automation workover machine upper tube manipulator. The manipulator comprises a main arm, a manipulator device and a hydraulic control system. The top of the main arm is provided with a top seat, the top seat is provided with a rotary oil cylinder, and the rear side of the main arm is provided with a sliding rail and a lifting cylinder; there are two manipulator devices, one of the manipulator devices is hinged to the top seat of the main arm by a hinge shaft to form a rotating manipulator, and the rotating manipulator can be rotated by 180 degreesaround the top seat by the rotary oil cylinder; another manipulator device is mounted on a sliding rail of the back of the main arm by a connecting arm to form a vertical manipulator, and the verticalmanipulator can move up and down along the sliding rail under the control of the lifting oil cylinder; the hydraulic control device controls the rotary oil cylinder, the lifting oil cylinder and themanipulator device to achieve the rotation and lifting and clamping actions. The manipulator achieves the lifting of an oil pipe by alternating switching-on and switching-off and upward and downward moving of the manipulator, thereby improving work efficiency and reducing labor intensity, and the safety is good.

Description

technical field [0001] The invention relates to a pipe-loading manipulator, in particular to a pipe-loading manipulator for a workover rig used on an offshore platform, and belongs to the technical field of petroleum workover. Background technique [0002] Workover operation is an important part of oilfield production and a key process to ensure stable oilfield production. Offshore workover operations have the characteristics of small site, complex and changeable weather, and high efficiency requirements. At present, most offshore workover operations are manual-based operations, including: moving slips, feeding and returning power tongs, lifting oil pipes to the drilling floor, opening and closing elevators, and piping on the second floor platform Wait. People stand on the second-floor platform, and the sea is very windy and rough, so there is great danger and low efficiency. Due to the particularity of offshore oil wells, the manipulators of the original onshore oilfield...
