Leakage-stopping mechanical hand of pipeline

Abstract

The invention relates to a leakage-stopping mechanical hand of a pipeline, which belongs to the technical field of pipeline maintenance mechanical equipment and is used for realizing the unmanned, fast, safe and high-quality leakage-stopping work during the leakage-stopping process of the pipeline. The technical scheme is as follows: the leakage-stopping mechanical hand consists of a top plate, aclamping hand and a leakage-stopping clamp, wherein the upper end of the top plate is connected below a lifting arm of a leakage-stopping engineering vehicle, the clamping hand and the leakage-stopping clamp are mounted below the top plate, the clamping hand consists of two opposite semi-annular clamps, the two opposite parts respectively comprise a connecting rod to be connected with two ends ofa clamping hydraulic cylinder, the leakage-stopping clamp consists of two opposite semi-circular pipes, and the two opposite parts of the clamping hand respectively comprise a connecting pin to be connected with the two semi-circular pipes of the leakage-stopping clamp. The leakage-stopping mechanical hand can realize opening, closing, enclasping, locking and other functions of the clamping hand through a hydraulic device, and realize the transverse movement of the leakage-stopping clamp to an oil leaking point of an oil pipe for stopping leakage. The leakage-stopping mechanical hand can realize the mechanical leakage-stopping operation under the different leakage states with high pressure and low pressure, ensure the safety, reduce the labor intensity and improve the working efficiency.

Description

technical field [0001] The invention relates to a manipulator for plugging a leaking pipeline and belongs to the technical field of pipeline maintenance machinery and equipment. Background technique [0002] In the transportation of oil and natural gas, pipeline transportation is the most important transportation method. However, due to natural and man-made reasons, oil and gas pipeline leakage accidents often occur. What is disturbing is that people's handling of oil and gas pipeline leaks is usually not much different from ordinary pipeline network maintenance, and often leads to major accidents due to the lack of professional leak plugging technology. [0003] In some areas, crude oil and refined oil pipelines have large drops and many ups and downs. When a leakage accident occurs and the pipeline is shut down, there is a problem that it is difficult to repair the pipeline section in the high static pressure area. At present, there are many kinds of emergency repair mea...
