Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] see Figure 1 to Figure 2 , a hydraulic pin-type platform lifting system, including a pile fixing frame, a balance assembly, a ring beam structure and a lifting cylinder, wherein the ring beam structure is an important force-bearing and force-transmitting component of the lifting system. The ring beam structure includes a fixed ring beam and a moving ring beam, and the moving ring beam and the fixed ring beam are arranged correspondingly; the fixed ring beam and the moving ring beam both include a guide plate 15 and a connecting plate welded as one in sequence 16. The support plate 17 and the ring beam assembly, the ring beam assembly is formed by connecting a plurality of main beams 1 and connecting beams 2 at intervals. The connecting beam 2 includes an inner plate 3 and an outer plate 4 arranged in parallel and spaced apart...

Abstract

Disclosed is a ring beam structure member manufacturing method in a hydraulic bolt type platform lifting system. The method includes: machining and assembling a first welding-fitting part (32), a second welding-fitting part (33) and a third welding-fitting part into a ring beam component; welding and fitting the ring beam component to the ring beam structure member. Assembly precision is guaranteed by adopting a ring beam part fixture (21) and a ring beam check fixture (35), welding deformation during the ring beam structure member manufacturing process is controlled by adopting a bolt seat anti-deformation fixture (20), an oil cylinder pin seat anti-deformation fixture (21), a double-layer intersecting-type fixture (13) and a horse plate (14), concentricity and planeness of a bolt seat (8) and an oil cylinder pin seat (9) are guaranteed, and requirements on opening size in a ring beam is met.

Description

technical field [0001] The invention relates to a ring beam structure, and more specifically relates to a method for manufacturing a ring beam structure in a hydraulic bolt-type platform lifting system, belonging to the technical field of self-elevating offshore platform lifting systems. Background technique [0002] Jack-up drilling platform (oil and gas compression platform) is currently the most widely used drilling platform at home and abroad. It has legs that can be raised and lowered freely. Hull, and keep the bottom of the hull a certain distance away from the sea surface; when the jack-up drilling platform is towed, the legs are retracted, and the hull is in a floating state. [0003] The lifting system matched with the jack-up drilling platform can drive the hull to move up and down along the legs. At present, the lifting system matched with the jack-up drilling platform is usually a hydraulic pin-type platform lifting system. The existing hydraulic pin-type platfo...
