Description

Technical Field

[0001] The utility model relates to the field of petroleum machinery, in particular to a straightening manipulator for oil pipe operations. Background Art

[0002] In the process of oil drilling and production, oil pipelines are important transportation pipelines, and their status directly affects the efficiency and safety of oil production. As oil production continues, oil pipelines will experience problems such as wear, corrosion, and deformation, and need to be regularly repaired and replaced. During the maintenance process, the oil pipelines need to be straightened to ensure the smooth progress of the maintenance work.

[0003] In the existing righting manipulator, the clamping jaws can be opened and closed by the push of the hydraulic cylinder. When the oil pipe needs to be righted, the hydraulic cylinder drives the clamping jaws to close and clamp the oil pipe. When adjusting the angle of the manipulator, the manipulator is installed on a rotatable platform, and the platform is driven to rotate by an electric motor or hydraulic motor, thereby driving the manipulator and the oil pipe to adjust the angle.

[0004] The existing device can only adapt to oil pipes within a specific diameter range. Different manipulators need to be replaced or complex adjustments need to be made for oil pipes of different specifications. The versatility is poor, and the clamping force control is not precise enough, resulting in damage to the oil pipe surface or unsatisfactory straightening effect, affecting the operation accuracy. The angle adjustment accuracy is not high, and it is difficult to achieve precise angle control, which may cause the oil pipe to fail to accurately reach the required position, affecting the operation quality. The range of adjustment angle is limited, and it cannot meet the needs of multi-angle adjustment of oil pipes in some complex operation environments. In response to the above problems, a straightening manipulator for oil pipe operations is proposed. Utility Model Content
