Welding tool for welding rack plate of pile of drilling platform and semicircular pipes

Abstract

The invention relates to a welding tool for welding a rack plate of a pile of a drilling platform and semicircular pipes. The welding tool comprises a platform and hoops used for fixing a rack plate and semicircular pipes, the platform is welded by a plurality of transverse H-shaped steel bars and a plurality of lengthwise H-shaped steel bars which are staggered, the lower end face of each transverse H-shaped steel bars are provided with a plurality of support legs uniformly arranged along a long axis direction, and the upper end face of each lengthwise H-shaped steel bars are provided with a plurality of rack plate fixing seats, uniformly arranged along a long axis direction, used for supporting the rack plate. Each rack plate fixing seat comprises a locking plate and a reinforcing bracket, the locking plate is rectangular and vertically fixed to the upper end face of each lengthwise H-shaped steel bar, and the upper end face of the locking plate is provided with a groove used for containing inserted lower end of the rack plate. A pair of hoops are disposed, each hoop is semicircular, and the hoops cooperate with each other and tightly hold the outer side surfaces of semicircular pipes at two sides. The welding tool provides a welding platform having a stable structure, the manufacturing efficiency and welding precision of a main chord, and the production cycle of the main chord can be shortened.

Description

technical field [0001] The invention relates to the technical fields of marine engineering and shipbuilding, in particular to a welding tool for rack plates and semicircular pipes in pile legs of drilling platforms. Background technique [0002] During the development of offshore oil and gas resources, the 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 and production platform in early production. The realization of these main functions mainly depends on its special features. Application of components such as legs, lifting systems, locking devices and outriggers. [0003] Such as figure 1 and figure 2 As shown, the legs of the self-elevating platform are hollow trusses, and the horizontal section of each floor is an equilateral triangle, including three vertical main chords 1, horizontal braces 2, and diagonal braces 3 arranged at three vertices. As w...

Problems solved by technology

[0004] When making the above-mentioned main chord 1, it is necessary to weld the semicircular tube 6 on both sides of the rack plate 5. At present, there is no welding tool for the welding of the rack plate and the semicircular tube, which affects the production cycle of the main chord.
