The invention provides an axial traction type repair operation device for connecting a submarine pipeline, which is applied to rapid repair of the submarine pipeline. The repair operation device adopts a left-right symmetric structure and is used for carrying out axial traction type repair operation process of connecting the submarine pipeline according to rapid clamping of a split type clamping device, an axial traction effect of a spline guide rail type traction body, an axial guide effect of a spline groove type guide moving body, and propulsion power provided by a hydraulic axial pusher and a hydraulic periphery pusher; and the clamping device adopts a split type cylinder body, underwater rapid clamping between the traction body and the submarine pipeline is completed through the clamping device, a submarine pipeline connector adopts a thick-wall barrel body and is used for fixedly connecting two pipe sections of the submarine pipeline, the traction body achieves the traction effect in the axial slippage process of the submarine pipeline connector and the guide moving body according to a spline guide rail, centering of the two pipe sections of the submarine pipeline is completed according to a traction main rod and a traction auxiliary rod, and the guide moving body is used for realizing the guide effect in the axial propulsion process of the hydraulic axial pusher according to movement pairs on a spline slide way and the spline guide rail.
Description
Technical field [0001] The invention relates to a device for repairing a submarine pipeline by an underwater production system in the field of marine engineering, in particular to an axial traction type repairing operation device adopting the technology of underwater connecting submarine pipeline. Background technique [0002] Submarine pipelines in the field of marine engineering are responsible for important production tasks for the transportation of underwater oil and gas well produced fluids, as well as qualified crude oil and associated gas. Due to their subsea operating conditions and the particularity of the surrounding seawater environment, there are media corrosion, ship anchoring, Risks such as geological disasters and third-party damage in marine development, once leakage occurs, not only cause marine environmental pollution, waste of oil and gas resources and production interruption, but also adversely affect the normal production and life of downstream and end users. ...
