Marine guidance piling pile gripper

Technical field

The present invention relates to a kind of ocean wind power mounting platform(Ship)Piling construction equipment, especially a kind of marine guidance piling Pile gripper, belongs to marine guidance piling pile holding technical field.

Background technology

China's ocean wind-powered electricity generation is also in the starting stage, and many equipment, which are required to relevant manufacturers research and development, manufacture, could break through ocean The piling construction of the bottleneck of wind-powered electricity generation, wherein piling bar is exactly the difficult point that marine wind electric field needs to face, especially in working water Deep big, piling bar diameter is big, the steel pile foundation difficulty of construction under the unrestrained high condition of wind disease is bigger.Pile gripper is exactly to solve offshore wind farm Foundation steel pipe pile(Hereinafter referred to as piling bar)The professional equipment of piling construction difficult point, the equipment is used for the position during stake under blower fan piling bar Put adjustment, hold guiding tightly to keep the appropriate location of piling bar constant;, can be to the perpendicularity of piling bar when piling bar bottom pile sinking operating mode It is adjusted;It can be oriented to during piling operating mode, aid in righting and perpendicularity to adjust.Existing pile gripper technology realizes arm and opened Close, pile holding clamping perpendicularity adjustment function behind bottom with guiding, position adjustment and piling bar, some pile grippers are also achieved to move back automatically Return inboard function.But existing pile gripper mechanism has a disadvantage that:

1)The mode realized when position adjustment and perpendicularity are adjusted is that the swing of another direction is moved in a direction(Rotate)'s Polar coordinates positioning method;This polar coordinates positioning method is inconvenient in actual mechanical process, not directly perceived, and finding anchor point needs Examination is grasped repeatedly.

2)Pile holding clamping performer dynamically reducing mechanism can not load and keep piling bar posture, it is ensured that mechanism and platform Safety, specifically have the following aspects:

A. jack or other mechanical structures are used, the destructible structure under the effect of high-torque load;Protected using hydraulic jack Hold position constant different from using oil cylinder holding position invariance control mechanism, hydraulic jack is held in place rear rodless cavity(Load Chamber)Valve port is closed, rodless cavity during return(Load cavity)Valve port opens pressure release oil return box, is passive type, it is impossible to active oil return. After positioning, because load cavity valve port is closed, outer load excessive easily causes jack superpressure, fixed structure piece and easily overloaded, very heavy Top and fixture restricted lifetime.Buffer unit is equally not added with come pile holding using common mechanical structure, then structure destructible, designed Structure of need is strengthened increasing.

B. the hydraulic jack despite the use of having carries out pile holding diameter regulation, plays certain cushioning effect, but control Hydraulic pressure decompression and overload protection are not considered in system, does not consider that pile jacking action sequence should be controlled under the influence of wave period power.
