Embodiment 1

[0022] like figure 1 As shown, the invention discloses a method for manufacturing pile legs of a rice-shaped support pipe. The three-dimensional forming of the pile leg includes the bulk stage of the diagonal brace pipe and the production stage of the side piece. The tube 1 and the horizontal support tube 2 are made into a rice-shaped support tube assembly, and the components are welded during the production stage of the side piece 3, and finally three-dimensionally formed. The rice-shaped support tube assembly consists of a vertical horizontal support rod 2 and two It consists of two diagonal braces 1 on the side.

[0023] like figure 2 As shown, the specific steps of the manufacturing method of the above-mentioned rice-shaped support tube assembly are as follows:

[0024] S1. Welding bracket preparation: The welding bracket is composed of several criss-cross rods A4, and the bracket is provided with a number of support seats 5 for limiting and supporting the diagonal supp...

Embodiment 2

[0029] In this embodiment, on the basis of Embodiment 1, in step S2, the outer end of each diagonal strut is fixed to the adjacent horizontal strut by a holding rod, and the holding rod is composed of a rod body B6 and two ends of the rod body B6. Hoop 7 forms.

[0030] In this embodiment, the diagonal support pipe 1 and the horizontal support pipe 2 are fixed and locked by holding the rod, so as to avoid the deviation of the diagonal support pipe 1 and the horizontal support pipe 2 during welding, facilitate the welding operation, and improve the welding quality and welding efficiency. Holding rods 6 are arranged at both ends of the horizontal support pipe, and are fixed by holding rods and diagonal bracing rods.

Abstract

The invention relates to a method for manufacturing pile legs of rice-shaped support pipes. The three-dimensional forming of the pile legs includes a stage of bulk assembly of diagonal brace pipes and a stage of making side pieces. The support tube is made into a rice-shaped support tube assembly, and the components are welded during the side piece production stage, and finally three-dimensionally formed. The rice-shaped support tube assembly consists of a vertical horizontal support rod and two diagonal braces on both sides. Composed of rods; the specific steps of the manufacturing method of the rice-shaped support tube assembly are as follows: firstly, the welding support is prepared, and the support is provided with a number of support seats for supporting the diagonal support pipe and the horizontal support pipe, and the positions of the support seats are respectively Correspond to the two ends of the diagonal support tube and the horizontal support tube; then fix the horizontal support tube and the diagonal support tube on the bracket and weld them. The advantages of the present invention are: the manufacturing method of the pile legs of the present invention converts a large amount of high-altitude diagonally braced pipe bulk operations to the ground, effectively reduces the difficulty of installing the pile legs, shortens the construction period, greatly reduces the construction cost, and shortens the length of the pile legs. Segmented three-dimensional molding cycle.

Description

technical field [0001] The invention relates to the technical fields of marine engineering and shipbuilding, in particular to a method for manufacturing pile legs of a rice-shaped support pipe. Background technique [0002] During the development of offshore oil and gas resources, the jack-up drilling platform is mainly used to drill oil and gas wells, and can also be used to drill production wells and workover operations, and can also be used as a drilling platform in early production. The realization of these main functions mainly depends on For the application of its special components such as pile legs, lifting systems, locking devices and cantilever beams. [0003] The jack-up drilling platform is loaded with drilling machinery, power, equipment, living equipment and a number of liftable pile legs. When drilling, the pile shoes at the bottom of the pile legs touch the bottom, and the platform is lifted off the sea surface to a certain height along the pile legs; The pl...
