Offshore buoyancy tank combination type adjustable fitting

Abstract

The invention discloses a maritime buoyancy tank combined type adjustable fitting convenient for the buoyancy tank assembly operation in maritime storms. The invention consists of a woggle connector and a shearing force connector. The woggle connector consists of two woggle connector seats, a long monaural slide block and a short monaural slide block, a long monaural connecting shaft, a short monaural connecting shaft, a connecting board, a circlip for shaft, a brake pin and an eyebolt. The two ends of woggle connector seats are provided with push-pull cut openings for the brake pin. The long monaural slide block is connected with the long monaural connecting shaft. The short monaural slide block is connected with the short monaural connecting shaft. The connecting shafts are respectively fixed on the connecting board. The end surfaces of the connecting shafts are respectively provided with the circlip for shaft. The brake pin is arranged in the push-pull cut openings for the brake pin. The end part of the woggle connector seat is fixed with the eyebolt. The shearing force connector consists of a round tube for the connector A fixed on the connector A seat and a semi-circle sleeve for the connector B fixed on the connector B seat. The invention realizes the redistribution of an external load in the inner part of the joint, simplifies the stress mode of the connectors as much as possible, realizes 'labor division loading' and improves the overall loading capacity of the adjustable fitting.

Description

technical field [0001] The invention relates to the field of connection joint equipment of offshore buoyancy tanks, more specifically, relates to a hinged joint used for rotational connection between buoyant tanks. Background technique [0002] There are two types of connection joints for offshore buoyant tanks: rigid joints and hinged joints. Rigid joints are used to connect several buoyant tanks into rigid units, and hinged joints are used to connect rigid units into large floating structures. At present, the hinged joints used for the rotating connection between floating tanks in China include the hinged joints used in the "3000-ton offshore floating tank dock". The hinge includes single lug, double lug, pin and cross shaft. The single lug and double lug are fixed at the end of the buoyancy tank module through the pin. When connecting at sea, it is necessary to connect the single and double lugs with a cross pin In general, the operation strength, difficulty and danger a...

Problems solved by technology

The hinge includes single lug, double lug, pin and cross shaft. The single lug and double lug are fixed at the end of the buoyancy tank module through the pin. When connecting at sea, it is necessary to connect the single and double lugs with a cross pin In general, the operation strength, difficulty and danger are relatively large. In the wind and waves, due to the complicated force on the hinged surface, the single and double ears are easy to twist off, so the adaptability to the sea wind and wave environment is poor.
