Description
Technical field
The present invention relates to offshore wind farm technical field of construction, in particular to a kind of offshore wind farm large-diameter pile overturns tooling
And method for turning.
Background technique
China marine wind electric field entered large-scale developing stage from 2018, year puts scale into operation and reaches
Ten thousand kilowatts of 300-400.Marine wind power plant large-diameter pile is a kind of main base form, accounting 40-50%.Single pile length 70-
100 meters, 6-9 meters of diameter, 800-1800 tons of weight.
But large-scale floating crane required for single pile pile sinking or the usual lifting owner suspension hook of jack-up unit and secondary suspension hook are in
Front-rear direction, i.e. crane arm support length direction arrangement lead to these equipments single pile when carrying out single pile and turning over operation
Length direction must be kept always with crane arm support length direction, i.e. front-rear direction.Because single pile length is larger, center of gravity usually exists
Length direction middle position moves up 3-5 meters of positions, causes using traditional turning tool and turn technology crane barge or crane
Amplitude needed for cantilever crane turns over stake is both greater than 50 meters or more substantially, greatly reduces the elevating capacity of crane.Such as one 2000
The crane barge of ton turns over technical solution using front and back single pile, lifting amplitude is at 50 meters in the case where tail hangs 2000 tons of maximum capacity
Be only capable of 1000 tons or so of weight of lifting when left and right, greatly reduce the lifting performance of crane, if desired complete 1000 tons with
The turn operation of upper single pile needs to be reconfigured one 500 tons or more of crane barge and the left and right directions that could complete single pile is cooperated to turn over
Operation, considerably increases cost at one 500 tons or so crane barge lease expenses ten thousand/moon of about 150-200.In addition, offshore construction operation

Having broken the case where major and minor suspension hook of conventional ocean lifting ship cantilever crane is front-rear direction can not left and right directions, i.e. single pile length side
To the technical barrier for turning over single pile vertical with crane arm support direction, the ocean arranged before and after the major and minor hook of elevator boom rack is realized
The left and right directions that lifting ship can carry out single pile turns over, and reduces the amplitude of crane arm, greatly improves and rises in the case of the construction operation
The crane capacity of heavy-duty machine reduces the investment of one large-scale auxiliary floating-crane equipment, substantially reduces cost, improves safety.
