Pipeline clamping device for vertical welding table

Abstract

The invention provides a pipeline clamping device for a vertical welding table. A column is perpendicular to a base, and one outside wall of the column is provided with a linear guide rail and a locking rack; a top cover of the top of the column is internally provided with a first motor, and the bottom of the column is provided with a sliding limit device used for preventing a cantilever from derailing; the outside wall, adjacent to the side of the linear guide rail, of the column is provided with an escalator, and the outside wall, opposite to the side of the linear guide rail, of the columnis provided with an electric control system; the cantilever is controlled by the first motor through a chain to do linear guide motion, and the locking rack is matched with a cantilever locking device, and used for preventing the cantilever from sliding down; one end of the cantilever is connected to the linear guide rail through a sliding component, while the other end of the cantilever is provided with a clamping component; clamping heads are controlled by a second motor of the clamping component through a lead screw to slide on clamping guide rails for clamping a pipeline; the base is fixedto ground by anchor bolts; the pipeline can be clamped in the pipeline welding process effectively and safely, and the welding deformation is avoided; and the pipeline clamping device has the effectsof high stability and reliability, and is flexible.

Description

technical field [0001] The invention relates to a pipeline clamping device of a vertical welding platform. Background technique [0002] The J-shaped pipe-laying method is currently proven to be the most suitable method for laying submarine pipelines in deep water and ultra-deep water. Because the pipeline enters the water at a nearly vertical angle, the overall shape of the pipeline is J-shaped, so it is named. Since the 1990s, the J-lay method has developed rapidly and has become widely used, and sometimes the only method available when deep sea areas are involved. The appearance of the J-type pipe-laying ship has broken the limitation of water depth on the laying of submarine pipelines, making it possible to explore and develop oil and gas in deep water above 3000m. The J-type pipe laying method is essentially one of the tension pipe laying methods. For different water depths and pipe diameters, during the laying process, the stress state of the pipeline can be improved ...
