Manufacturing method of launching barge rocker arm hinged support

Abstract

The invention relates to a manufacturing method of a launching barge rocker arm hinged support. A bed-jig for manufacturing the rocker arm hinged support is firstly manufactured, assembly and welding processes of a rocker arm hinged structure are performed on the bed-jig, the welding process is carried out after assembly is fully completed, by using the bed-jig, horizontal overhead position welding in the traditional welding process is changed into horizontal fillet welding, thus the operation difficulty is lowered, the accuracy and efficiency of welding are improved, synchronous symmetrical welding from the middle to both ends is performed, a single welding method in the prior art is changed, and thus structure deformation due to too high local temperatures in the welding process can be effectively avoided. According to the invention, the special bed-jig is designed, structure assembly and welding processes of the rocker arm hinged support are optimized, the manufactured rocker arm hinged support can meet the requirements for precision and structural strength, correction work in view of the structural deformation can also be effectively avoided, thus the production difficulty is reduced, the efficiency is greatly improved favorably, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ship devices, in particular to a method for manufacturing a rocker hinge support of a launching barge. Background technique [0002] With the development of offshore oil engineering, there are more and more newly developed oil fields, large jackets, block sliding launches and float-over projects are increasing, and the requirements for engineering equipment are also getting higher and higher. The launching barge is a kind of engineering equipment specially used for launching large equipment such as large jackets, and the rocker arm system is the key system of the launching barge. It is subject to a huge bearing capacity when the jacket and other equipment are launched, and has special requirements High, the materials used are high-strength thick steel plates, especially the supporting structure of the rocker arm—the hinge support, which basically bears the entire weight of the jacket and other equipment d...

AI Technical Summary

Problems solved by technology

[0003] In view of the strict requirements on the structure, precision, strength and manufacturing process of the rocker hinge support of the launching barge, it is difficult to manufacture the rocker hinge support of the launching barge in the prior art, and it is easy to appear during the structural assembly and welding process. Deformation occurs due to excessive local heating, and a large number of corrections are required to correct the structural deformation. The process is complicated, the efficiency is low, and the production cost is high.
