AI Technical Summary
Technical Problem
The splicing process of existing LNG receiving terminal pipelines is cumbersome and time-consuming. Traditional flange connections require tightening bolts one by one, which is laborious and can easily lead to fatigue.
Method used
The design employs an external gear ring and a rotating gear meshing connection. By driving any set of rotating gears, multiple sets of rotating rods can be rotated synchronously, achieving a tight connection between the first and second rings, simplifying the operation process and improving efficiency.
Benefits of technology
It enables rapid pipe splicing, eliminating the need for tightening each pipe individually, improving operational efficiency and labor-saving, and ensuring the simplicity and safety of the splicing process.

Abstract
This utility model belongs to the field of pipeline technology and discloses a rapidly assembled LNG receiving station pipeline, including two sets of pipelines. Each set of pipelines has a first ring and a second ring. A rotatable external gear ring is located on one side of the first ring, with a rotating gear meshing with its outer side. A rotating rod is rotatably mounted on the first ring, and the rear end of the rotating rod is threaded. Compared with the prior art, this utility model has the following advantages: By evenly arranging multiple sets of rotating gears circumferentially on one side of the first ring, each set is coaxially fixed with the threaded rotating rod. The rotating rod is adapted to the nut of the second ring, and all rotating gears mesh with the external gear ring. During operation, driving any set of rotating gears will cause all rotating gears to rotate synchronously through the external gear ring, thereby allowing multiple sets of rotating rods to be simultaneously screwed into the nut, ensuring a tight connection between the first and second rings to complete the pipeline splicing. This eliminates the need for individual tightening, making it highly efficient and labor-saving.
