Problems solved by technology

The bolt connection method is a widely used and very mature flange system connection method for marine pipeline maintenance in shallow water areas. Usually, divers operate to complete the sea pipe flange assembly, bolt installation and stretching, but for water depths exceeding 300 meters The maintenance of deep-water marine pipelines needs to be carried out by underwater robots. Therefore, how to realize flange assembly, bolt installation and stretching work without divers and only rely on underwater robots has become a restrictive bolt connection method in deep-water marine pipelines. A challenge for maintenance applications

Embodiment Construction

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like figure 1 As shown, the sea pipe flange pair connection installation device according to an embodiment of the present invention includes a frame main body 10, a support rod assembly 20, and bolts for opening and closing clamping on sea pipes and inserting bolts into sea pipe flanges. Fixture 30, used for opening and closing clamping on the docked sea pipe flange to center the sea pipe flange 40, used for opening and closing clamping on the sea pipe and screwing in the nut Bolts are nut clamps 50 that fasten the flanges of the butt sea pipes.

[0029] The frame main body 10 is formed with channels running through its opposite ends, the support rod assembly 20, the bolt clamp 30, the flange clamp 40 and the nu...

Abstract

The invention discloses a subsea pipeline flange assembling, connecting and installing device which includes a frame main body, a support rod assembly, a bolt clamp clamped on a subsea pipeline in anopening-and-closing manner and inserting bolts into subsea pipeline flanges, a flange clamp clamped on the docking subsea pipeline flanges in an opening-and-closing manner to center the subsea pipeline flanges and a nut clamp clamped on the subsea pipeline in an opening-and-closing manner and screwing nuts into the bolts to fasten the docking subsea pipeline flanges. The support rod assembly is arranged in the frame main body in an extending manner in the axial direction of the subsea pipeline and can move back and forth in the vertical direction relative to the frame main body, the bolt clamp, the flange clamp and the nut clamp are sequentially arranged on the support rod assembly, and the bolt clamp and the nut clamp can move back and forth in the axial direction of the subsea pipeline along the support rod assembly. The subsea pipeline flange assembling, connecting and installing device is suitable for control over underwater robots, is used for performing underwater subsea pipelineflange pairing and bolt installing, achieves the aim of deep-sea subsea pipeline maintenance, and is safe and efficient.

Description

technical field [0001] The invention relates to the technical field of sea pipe maintenance, in particular to a sea pipe flange pair connection installation device. Background technique [0002] There are two main ways to connect the flange system of deepwater sea pipe maintenance: bolt connection and claw connection. The claw connection method has high requirements for the coaxiality of the prefabrication of the sea pipe, and it is a difficult point for the quality control of the prefabrication of the sea pipe. The bolt connection method is a widely used and very mature flange system connection method for marine pipeline maintenance in shallow water areas. Usually, divers operate to complete the sea pipe flange assembly, bolt installation and stretching, but for water depths exceeding 300 meters The maintenance of deep-water marine pipelines needs to be carried out by underwater robots. Therefore, how to realize flange assembly, bolt installation and stretching work withou...
