Description
Technical field
The utility model relates to a kind of climbing ladder apparatus more particularly to a kind of offshore wind farm O&M reversible ladder to fill
It sets.
Background technique
In recent years in domestic or even global range, offshore wind farm industry is flourished.Wind energy turbine set installed capacity is got over
Come bigger, blower quantity is more and more, and the depth of water is also gradually deepened, this brings more risk to the O&M of marine wind electric field and chooses
War.Since maritime environment is complicated and changeable, O&M ship displacement is big by wave effect, when close to offshore platform (include sea turn
Machine platform and offshore boosting station platform) when, O&M ship shakes acutely, and personnel's landing platform ladder is extremely difficult and has great
Risk.For marine live O&M, most dangerous link is returned no more than personnel from O&M ship landing platform and from platform
Therefore O&M ship reduces the risk of the link, guarantee that operation on the sea personnel safety becomes urgent problem to be solved.
Offshore wind farm project mostly uses greatly fixed vertical ladder to design at present, since ladder is fixed on platform, and O&M
Ship and platform relative motion are larger, be easy to cause personnel to step on platform difficulty, in the presence of very big security risk when at sea stormy waves is big；
B.s.l. is in for a long time additionally, due to ladder lower part, ladder seriously corroded and is covered with marine growth, is unfavorable for operation maintenance personnel
Climbing.Domestic and international some solutions proposed for this problem are all made of the scheme to the transformation of O&M ship, as belt track is mobile
Modes, these modification schemes such as inclined ladder, flexible aisle with pedestal need to add fluid pressure drive device, and not only manufacture is complicated, makes
Valence is higher.
Utility model content
In order to solve shortcoming present in above-mentioned technology, the utility model provides a kind of offshore wind farm O&M with can
Convertible climbing ladder apparatus.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of offshore wind farm O&M is with can
Convertible climbing ladder apparatus, including O&M ship, offshore platform tubular pole further include overturning ladder, lifting cucurbit；On offshore platform tubular pole
It is provided with blower ladder platform, the one end for overturning ladder is connected by pin shaft with blower ladder platform, and the other end passes through idler wheel
It is erected on the deck of O&M ship；Since idler wheel can roll above deck, when O&M ship is with wave motion, ladder energy shape is overturn
At stable movement mechanism, to guarantee the safety of ascending stair personnel；
The overturning one end of ladder with idler wheel is connected with cucurbit chain, and the other end of cucurbit chain is coiled from lifting cucurbit
Extend still further below afterwards；Overturning ladder is connected by cucurbit chain with lifting cucurbit；Lifting cucurbit has automatic dead-locking function；

When, starting lifting cucurbit, overturning ladder is dug under the drive of cucurbit chain upwards, and passes through the out of service of lifting cucurbit
To carry out locked and fixed.
Overturning ladder is placed into when in use on O&M ship, is drawn high when not in use by cucurbit suspension centre fixed to offshore platform
On tubular pole.
The fixed strut of ladder, ladder are fixedly installed on offshore platform tubular pole among cucurbit suspension centre and blower ladder platform
Fixed strut is used to play fixed supporting role to overturning ladder after overturning ladder is packed up.
Blower ladder platform is set to the splash zone on sea or more, makes to overturn ladder when packing up positioned at sea splash zone
Top avoids the slap by wave and the erosion of seawater, marine growth.
The intersection on offshore platform tubular pole and sea level is provided with by ship fender, and O&M ship passes through flat by ship fender and sea
Platform tubular pole is in contact.
When the utility model effective solution offshore wind farm operation maintenance personnel from marine O&M ship logs in offshore platform, O&M
Ship shakes, heaves bring risk problem, overcomes the deficiency of current offshore platform ladder technology, it is ensured that marine O&M people
Member logs in the safety of offshore platform；The device is easy to operate simultaneously, cheap, safer reliable, has very wide
Application prospect.
