Abstract
One is bearing pin pull erecting stage under water, be provided with: a platform base, be fixed on several platform base supporting legs below platform base, be fixed on the several platform struts above platform base, be fixed on upper mounting plate above several platform strut, wherein, the center of upper mounting plate is provided with the through hole I for pull cucurbit chain, and the center of platform base is provided with a through hole II passed through for the pull end of bearing pin; The top of upper mounting plate is provided with a pull cucurbit, and the cucurbit chain of this pull cucurbit is through the through hole of upper mounting plate and the through hole of platform base.The present invention can not only make diver control bearing pin through dynamics, speed and bearing pin position in pin shaft hole process, and, substantially increase the speed that diver installs bearing pin, efficiently solve the problem of diver's operational difficulty under water.
Description
Technical field
The present invention relates to erecting stage, particularly relate to one bearing pin pull erecting stage under water.Belong to Offshore Engineering field.
Background technology
Off-shore oil field Floating Production oil storage system (FPSO) is a kind of crude oil, the storage of natural fuels, production and processing, outer defeated of being mainly used in, and for oil field provide water, electricity and life support large-scale production oil storage tanker, generally existing: 5 ~ 300,000 tons, is the core facility that offshore oil and gas is produced.
Mooring system primarily of single point mooring's head, shake gram (YOKE) and mooring leg composition, mooring leg and shake gram (YOKE) as cacheable connecting device, by off-shore oil field Floating Production oil storage system (FPSO) permanent mooring on single-point, make off-shore oil field Floating Production oil storage system (FPSO) can with the wind, wave, flow and rotate around single-point.Seabed oil, gas, water pipe and cable are all connected on the flexible pipe between mooring head and oil field Floating Production oil storage system (FPSO) by single-point, for transferring oil, gas, water, electricity, to ensure the normal production in oil field.
In the installation of oil-gas field single buoy mooring system, being integrated by pinned connection normally by anchor chain and floating drum.Its advantage is, under tide and the effect of surging, floating drum can fluctuate, and pinned connection makes mooring anchor chain and floating drum connection location place can relatively rotate state, effectively offsets fatigue damage.But because bearing pin deadweight reaches up to a hundred kilograms, and the working space at floating drum place is limited, diver is under water by very difficult, consuming time longer for the operation during pin shaft hole of bearing pin through anchor chain and floating drum.
Summary of the invention
Main purpose of the present invention is the above-mentioned shortcoming overcoming prior art existence, and one bearing pin pull erecting stage is under water provided, it can not only make diver control bearing pin through dynamics, speed and bearing pin position in pin shaft hole process, and, substantially increase the speed that diver installs bearing pin, reduce construction period, efficiently solve the problem of diver's operational difficulty under water.
The object of the invention is to be realized by following technical scheme:
One is bearing pin pull erecting stage under water, it is characterized in that: be provided with: a platform base, be fixed on several platform base supporting legs below platform base, be fixed on the several platform struts above platform base, be fixed on upper mounting plate above several platform strut, wherein, the center of upper mounting plate is provided with the through hole I for pull cucurbit chain, and the center of platform base is provided with a through hole II passed through for the pull end of bearing pin; The top of upper mounting plate is provided with a pull cucurbit, and the cucurbit chain of this pull cucurbit is through the through hole of upper mounting plate and the through hole of platform base.
Described upper mounting plate and platform base are discoid, and upper mounting plate is identical with the diameter of platform base.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, it can not only make diver control bearing pin through dynamics, speed and bearing pin position in pin shaft hole process, and, substantially increase the speed that diver installs bearing pin, efficiently solve the problem of diver's operational difficulty under water.
