Abstract

The invention provides a special positioning and clamping device for an automatic submerged pipe flange connecting machine. The device comprises a master jaw 1, a hinged hydraulic cylinder 2, a jaw 5, a hydraulic cylinder mounting lug 6 and a jaw mounting lug 8, wherein the hydraulic mounting lug 6 is fixed on the master jaw 1; the hinged hydraulic cylinder 2 is connected with the master jaw 1 through the hydraulic mounting lug 6 and is connected with the jaw 5 through a pin shaft 3; the jaw 5 is connected with the master jaw 1 through a rotating shaft 4; and the jaw mount lug 8 has two pieces which are welded at two sides of the master jaw respectively. The invention provides a positioning and clamping device for a deepwater automatic flange connecting machine which can adapt to deep-sea environment and meet the operational requirements of the deepwater automatic flange connecting machine on positioning and clamping.

Description

(1) Technical field [0001] The invention relates to a positioning and clamping device on an automatic working tool, in particular to a mechanical device applied to automatic bolt connection of deep-sea oil pipeline flanges. (2) Background technology [0002] There are many ways to connect the flanges of deep-sea submarine pipelines, among which the bolt connection is the method with the lowest cost and the highest connection reliability. Deep sea operations cannot utilize divers, but various automated machines can be used. The simple process of flange bolt connection of deep-sea pipelines is that the H-frame is controlled by the ROV (Remotely Operated Vehicle) to support the pipelines that need to be connected on the seabed, and then the axial and radial positions of the pipelines are realized by the alignment tool. After that, the ROV manipulates the automatic flange connection tool to complete the bolt connection of the pipe flange. In order to ensure the normal progress...
