A flexible connector and floating platform connection structure

Abstract

The invention discloses a flexible connector comprising a clamping base and a base, wherein the clamping base is of a revolving body structure; the clamping base comprises a body with a top hat cross-section and a clamping part fixedly connected to the top of the body; a clamping groove is arranged on the clamping part; the base is a revolving body with a top hat cross-section; the top of the baseis inserted into the lower cavity of the body of the clamping base; a rubber spring pad is arranged between the upper surface of the base and the lower surface of the body of the clamping base; the body of the clamping base, the rubber spring pad and the base are fixedly connected; and the external diameter of the side edge of the base is greater than the external diameter of the side edge of thebody of the clamping base. The flexible connector disclosed by the invention is simple and compact in structure and is capable of effectively reducing the load so that the high-strength rubber material can transfer the load during deformation such as tension-compression, bending and the like, so as to ensure the safe operation of a super-large floating body. In addition, the connector is of a modular structure for easy replacement and maintenance. The floating platform connection structure matched with the flexible connector can realize quick connection and detachment and six degree of freedom elastic restraint.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a flexible connector and a floating platform connection structure. Background technique [0002] The ultra-large floating structure is a major high-end marine engineering equipment based on the maintenance of national marine rights and interests and the development of deep-sea resources. It can be used as an open-sea rapid transportation hub, a large-scale deep-sea development and operation platform, an ocean-going material storage relay station, and a comprehensive military platform for rapid response to maneuvering at sea. Due to the huge size of the ultra-large floating structure, it is destined to adopt a modular assembly structure in terms of construction, transportation and daily maintenance. Therefore, the connector has become a key component of the modular structure. In the past, people used rigid or semi-rigid connectors such as welding and hinges, which of...

Problems solved by technology

Therefore, the connector has become a key component of the modular structure. In the past, people used rigid or semi-rigid connectors such as welding and hinged joints, which often led to stress concentration and the structure was unbearable.

[0003] Chinese invention patents "Connectors and connection methods between modules of super-large marine floating structures (application number: 201210496392.6)", "connectors and connection methods applied to modules of super-large marine floating structures (application number: 201410199638.2) ", "A marine floating body with power and adjustable negative pressure vacuum suction cup connector (application number: 201610161973.2)", etc., proposed several flexible connector devices for the modular connection of super large offshore floating structures, and realized The function of quick installation and disassembly, but most of them involve complex actuators such as hydraulic cylinders, electromagnetic chucks, vacuum chucks, etc. For the harsh offshore environment where ultra-large floating structures are located, their safety and reliability are difficult. ensure

[0004] To sum up, the connection between the super-large floating structures and the structure of the connection in the prior art mainly have insufficient connection strength, and it is difficult to achieve rapid assembly and release.
