Offshore buoyancy tank combination type adjustable fitting

Abstract

The invention discloses a combined articulated joint of a floating tank on the sea. The present invention is composed of a flexible connector and a shear force connector. The flexible connector consists of two flexible connector seats, a long single-ear slider, a short single-ear slider, a long single-ear connecting shaft, and a short single-ear The connecting shaft, the connecting plate, and the shaft are composed of elastic retaining rings, gate pins and eyebolts; the two ends of the flexible connector seat are provided with openings for inserting and withdrawing gate pins, the long single-ear slider is connected with the long single-ear connecting shaft, and the short The one-ear slider is connected to the short one-lug connecting shaft; the connecting shafts are respectively fixed on the connecting plates, the end faces of the connecting shafts are respectively provided with elastic retaining rings for the shaft, and the gate pins are provided in the openings of the gate pin insertion holes, and the flexible connector An eye screw is fixed at the end of the seat; the shear connector includes a round tube of connector A fixed on the seat A of the connector and a semi-circular sleeve of the connector B fixed on the seat B of the connector. The invention realizes the redistribution of the external load inside the joint, and simplifies the force bearing form of the connector.

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.
