Making method of hawsepipe for single point mooring buoy main body

Abstract

The invention discloses a making method of a hawsepipe for a single point mooring buoy main body. The hawsepipe comprises an upper cylinder and a lower saddle-shaped structure, wherein the saddle-shaped structure comprises a semi-straight pipe as well as a triangular plate with an arc and a bent pipe, wherein the semi-straight pipe is positioned on a half side; the triangular plate with the arc and the bent pipe are positioned on the other half side and spliced with the side end surface of the semi-straight pipe; the lower part of the saddle-shaped structure is horizontally embedded with an embedding bottom plate and an embedding plate in parallel; and the lower part of the saddle-shaped structure is additionally provided with reinforcing ribs and an enclosure plate. Transitional circular arc plates are also arranged on two sides of the upper part of the saddle-shaped structure. Through designing a machining process, the making method of the hawsepipe for the single point mooring buoy main body, disclosed by the invention, has the advantages that errors are reduced and the machining precision is enhanced because a hawsepipe structure is formed; and the invention integrally provides the simple and convenient method with high machining quality and low machining cost.

Description

technical field [0001] The invention relates to a manufacturing method of an anchor chain, more specifically, relates to a manufacturing method of an anchor chain cylinder in a single-point mooring buoy in marine engineering. Background technique [0002] Such as figure 1 As shown, the single-point mooring buoy is a closed cylinder structure with a diameter of about 12 meters and a height of about 5 meters (shown by the number 61 in the figure), which floats on the sea surface as a whole during the working state, and moors and fixes the ocean tanker. It itself is held on the seabed by 6 large anchor chains to keep its position. [0003] Existing technologies mostly rely on casting and forging methods to make them. Due to the large volume and weight of the anchor chain cylinder, it has caused complex production problems, especially if it is slightly improper and does not meet the processing accuracy requirements, the product accuracy cannot be guaranteed, resulting in waste....

[0003] Existing technologies mostly rely on casting and forging methods to make them. Due to the large volume and weight of the anchor chain cylinder, it has caused complex production problems, especially if it is slightly improper and does not meet the processing accuracy requirements, the product accuracy cannot be guaranteed, resulting in waste. , so the material loss is also larger
