Description
Technical Field
The utility model relates to a submarine flange positioning instrument, in particular to a digital display type submarine flange positioning instrument for anti-abrasion protection of a vacuum ladle beam column and a ladle clamp.
Background
At present, engineering technicians in China basically master the design and construction technology of submarine oil and gas pipelines within hundred meters of water depth, and the special technology and capability with China offshore features are formed.
Submarine pipelines are mostly connected by direct manipulation by divers or by using underwater sealed cabins as working spaces. Since the diver cannot directly construct on the deep sea floor, the diver works only with the assistance of the underwater robot ROV (Remotely Operated Vehicle). The connection method of submarine pipelines in deep water areas is mainly a mechanical connection method and can be roughly divided into 3 types: jaw-type connections, clamp-type connections, and flange-type connections. The flange type connection is a common mechanical connection mode, and is the most common tie-back mode of the current ocean submarine pipeline.
The flange connection of submarine pipelines is accompanied by a plurality of connection projects of submarine pipeline flange expansion bends, and in the projects which are already built and are ready to be built, almost every project has the connection of submarine pipeline flange expansion bends. The connection of the expansion bend of the marine pipe flange means a connection between the riser end flange and the flat pipe end flange of the marine pipe by the expansion bend. The expansion bend is a bent sea pipe segment connecting the platform riser with the subsea pipeline. After the submarine pipeline is paved near the ocean platform by the pipe-laying ship, the submarine pipeline needs to be connected with the ocean platform riser by means of expansion bends. The oil of the ocean platform is transported out through the vertical pipe, the expansion bend and the sea pipe.
Past experience has shown that the most critical procedure for connecting marine pipe flanges for expansion bending is the measurement of the relative spatial position and azimuth angle between the marine pipe flanges, namely: and measuring various relative spatial positions and orientations of the distance, the angle, the height difference and the like between the bottom flange of the vertical pipe and the flat pipe flange of the sea pipe. In order to accurately pre-manufacture the expansion bend to be installed, then smoothly perform the installation work, shorten the construction period, reduce the offshore construction cost and reduce the waste, so that various parameters of flanges at two ends of the expansion bend must be accurately measured underwater. Only accurately measuring the parameters and then laying out the sample on the deck of the construction ship according to the parameters, so that the expansion bend can be accurately prefabricated, the expansion bend can be smoothly installed, and the installed flange pressure test qualification rate is guaranteed to be high.
At present, a common mechanical flange positioning instrument needs a plurality of divers to cooperatively use when measuring relative position parameters, the device is fixed on a flange of a pipeline to be measured, the device is connected through a steel wire rope, the relative angle of the two flanges is displayed through a mechanical dial after the steel wire rope is tightened, the length of the steel wire rope to be measured is required to be measured on the shore after underwater marking, and after repeated measurement, expansion bends are customized according to measured data. The device is relatively complex to operate. Because the submarine environment is severe, the visual field of divers is limited, the mechanical angle scale is difficult to read directly, and each time the measured parameters are required to be matched with a ship team of a project, the cost is high, and the construction period is long.
Therefore, there is a particular need for a digital display type subsea flange locator that solves the above-mentioned existing problems.
