Description
Technical field
The present invention relates to a kind of elevating mechanism and its elevating method, especially a kind of self-lifting offshore wind power job platform liter
Descending mechanism and its elevating method.
Background technique
With the exploitation of offshore wind farms and the addressing position of optimization ocean wind power plant, marine wind energy development trend is above
The mega project and deep water sea area that hundred Fans are characterized, assembling can encounter more difficulties, performance to installation ship and
Portability requirements are higher.Wind-powered electricity generation installation exercise needs in ocean are often moved to another position, jacking system from a position
Work is frequent.Lifting speed has larger impact, the promotion speed of wind turbine installation vessel jacking system to activity duration and working efficiency
Demand for development has characteristic faster, more reliable.
From the point of view of the current domestic jack-up unit installed for wind-powered electricity generation, since the bearing mode of wind-powered electricity generation mounting platform is determined
Fixed, hydraulic bolt formula driving method is in the majority, and since hydraulic bolt formula is intermittent climbing device, most obvious disadvantage is
Lifting speed is slow.
Summary of the invention
Fast, reliable self-lifting offshore wind power operation that technical problem to be solved by the invention is to provide a kind of promotion speed
Platform lifting mechanism and its elevating method.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of self-lifting offshore wind power job platform elevating mechanism, it is characterised in that: include wedge bracket, slide block guide rail, cunning
Block, pull rod, lifting cylinder, bolt and plugging pin oil cylinder, wedge bracket lower end are fixed on hull, and wedge bracket is set on the outside of spud leg simultaneously
And the Slideslip outside spud leg, slide block guide rail can be arranged along vertical direction in wedge bracket side, two pull rods are vertically arranged in
Both ends on the upside of slide block guide rail, pull rod lower end are hinged on the upside of slide block guide rail, and pull rod upper end is hinged on the upside of slide block guide rail, and sliding block is sliding
Dynamic to be arranged on slide block guide rail and slide along the vertical direction, two lifting cylinders are vertically arranged on the upside of sliding block, lifting
On the upside of the hinged slide block guide rail of cylinder upper end, lifting cylinder lower end is hinged on sliding block, and plugging pin oil cylinder is horizontally disposed and is fixed on
On sliding block, bolt is arranged radially along spud leg and bolt end connect with plugging pin oil cylinder and radially moved by plugging pin oil cylinder drives edge spud leg
Dynamic, spaced set has several and matched circular hole of bolt along the vertical direction on spud leg.
Further, the wedge bracket lower end is provided with flexible cushion block, and slide block guide rail lower end passes through flexible cushion block setting and exists
On the upside of hull.
Further, the wedge bracket is cuboid framework.
Further, four sides of the wedge bracket are respectively arranged with one group of slide block guide rail, sliding block, pull rod, lifting oil
Cylinder, bolt and plugging pin oil cylinder.
A kind of elevating method, it is characterised in that comprise the steps of:
Step 1: four sliding blocks are in different height in initial position, are divided into 4 layers, and the 1st layer is 1# sliding block, and second
Layer is 2# sliding block, and third layer is 3# sliding block, and the 4th layer is 4# sliding block, in the bolt insertion spud leg pin hole on sliding block；
Step 2: when platform in place after spud leg need transfer to contact seabed piling after again by platform lift away from sea carry out wind
Electric installation, spud leg is spud leg bottom surface far from hull downward actuation with respect to the action process of hull in the process, in stake
System load is not identical when leg decentralization and platform rise, and is adjusted by the hydraulic system pressure of platform and adapts to load change；
Step 3: pile pulling is carried out after construction end rear platform needs to transfer to offshore floating and receives stake operation, herein mistake
Spud leg is that spud leg bottom surface is acted close to hull upwards with respect to the action process of hull in journey, the system when platform is transferred and receives stake
Load is all different, and is adjusted by the hydraulic system pressure of platform and is adapted to load change.
Further, the detailed process of step 2 are as follows:
