Abstract
The present invention relates to fixed guide tube frame type marine platform shock absorption installation. The invented shock absorption layer is set between fixed guide tube frame and platform, each shock-absorber unit of shock absorption layer includes damper, shock absorption pad, the damper is fixed between terminal cap and cross beam, shock isolation pad is fixed between two side terminal caps of damper and cross beam. The present invention can reduce harm of marine environmental power action against the platform.
Description
Technical field: the present invention is used for the earthquake isolating equipment of ocean platform, particularly the earthquake isolating equipment of A/C posture ocean platform.
Background technology; Ocean platform is the infrastructure of marine resources development, A/C posture ocean platform is the primary structure form of middle shallow sea ocean platform, it adopts stake to pass the conduit leg prefabricated jacket is fixed on the sea, jacket and stake are the load-supporting parts of platform, and miscellaneous equipment layer and workspace then are located on the platform.Under the effect of marine environment dynamic loadings such as wind, wave, stream, ice and earthquake, the vibrations of jacket offshore platform reaction is very violent.Traditional anti-shock methods is by raising structural element strength and stiffness, or utilizes the elastic-plastic deformation of structural element to consume vibration energy, thereby satisfies every requirement of ocean platform needs.But when shaking by the strength and stiffness opposing that improves structural element, comfort level often can not satisfy, and utilizes the elastic-plastic deformation of structural element, more is easy to generate the damage that can not repair.In recent years civil engineering structure energy-dissipating and shock-absorbing system of Ti Chuing and base isolation system can alleviate the vibrations reaction of structure more effectively.Because the own characteristic of structure and the spatial constraints that energy-consumption shock-absorption device can be set, the common energy-dissipating and shock-absorbing measure of offshore platform structure is difficult to obtain promising result; In addition, be limited to the characteristics of platform structure, can not carry out base isolation in the position of stake, and common shock insulation layer is set between jacket and upper brace, then will produce unacceptable over-large displacement at the shock insulation layer.
Summary of the invention: for solving the deficiency that prior art exists, the invention provides a kind of fixed conduit frame type sea plat form shock isolation installation, it includes A/C frame 1, platform 3, it also includes shock insulation layer 2, and shock insulation layer 2 is fixed between the crossbeam 3-1 of the end cap 1-1 of A/C frame 1 and platform 3 bottoms.Each shock insulation unit of shock insulation layer 2 includes damper 5, shock insulation pad 6; Damper 5 is fixed between end cap 1-1 and the crossbeam 3-1, is fixed with shock insulation pad 6 respectively between the both sides end cap 1-1 of damper 5 and the crossbeam 3-1.The present invention is provided with the shock insulation layer and makes it to produce to concentrate and is out of shape, be in the abundant depletion energy of damper wherein, because the quality of platform is much larger than the quality of jacket, make Local Damping can be converted into integrally-built damping, thereby alleviate integrally-built vibrations reaction, it reduces effect to platform structure vibrations displacement and acceleration can surpass 30%, under various marine environment dynamic actions, can satisfy the comfort level of ocean platform and can reduce its damage to ocean platform.
Description of drawings: Fig. 1 is an overall structure schematic diagram of the present invention, and Fig. 2 is the structural representation of 2 one shock insulation unit of shock insulation layer, and Fig. 3 is the plan view of the shock insulation layer 2 that is made of three shock insulation unit, and Fig. 4 is the plan view of the shock insulation layer 2 that is made of four shock insulation unit.
