Problems solved by technology
[0005] There is also a U.S. Patent Application No. 4708376. Compared with the technical solution in the U.S. Patent Application No. 4730853 patent document, a sealing plate is added to the bottom of the connector to prevent foreign matter from entering the connector; The shape of the pipe has changed, and the local structure has changed when the outer diameter of the pipe is different, but the adapter fits with the cylindrical surface of the claw body, and there is stress concentration

The invention provides a hydraulic claw pipe connector, which comprises a shell which is formed by a bottom plate, a lower shell, an upper shell and a connecting annular plate, wherein, a pipe connecting body is arranged on the connecting annular plate; a cylindrical hole is arranged on the pipe connecting body; a claw shaft on a claw is positioned inside the cylindrical hole on the pipe connector; the tail of the claw is arranged outside the pipe connecting body through a spring and provided with a claw tail conical surface and the other end of the claw is provided with a connecting surface which is matched with the prior pipe connecting surface at the sea bottom; a hydraulic cylinder is arranged on the bottom plate; a drive ring is arranged on a double acting piston of the hydraulic cylinder; and a drive ring open taper hole which is matched with the claw tail conical surface is arranged on the drive ring. The hydraulic claw pipe connector is accurate in positioning, flexible in rotating and reliable in sealing, can realize automatic detachable vertical connection, horizontal connection and bridge connection between deep water subsea pipelines and between pipelines and well heads, and have wide application prospect in development of deep-sea oil-gas field.
Description
(1) Technical field [0001] The invention relates to a pipeline connection device, in particular to a remote control seabed pipeline connector. (2) Background technology [0002] Jaw style pipe couplings are commonly used to provide remote actuated connections between pipes or other fittings. The report that can be found in some published materials and is relatively related to the application of the present invention is the technical solution disclosed in the patent document of US Patent Application No. 4153278. [0003] The power source of the technical solution in the patent document of U.S. Patent Application No. 4153278 is provided by a hydraulic cylinder, and the piston of the hydraulic cylinder drives the drive ring to move up and down, so that the jaws rotate to realize opening and closing. When closing, one type is the inner upper part of the jaws. The lower part is a part of the spherical hole that matches the spherical surface of the matching pipe end flange to rea...
