Description
Technical field
The utility model is related to platform more particularly to a kind of mobile piling assistance platforms.Belong to Offshore Engineering neck
Domain.
Background technology
At present, accurate pile sinking is the difficult point and key point of piling work, especially at sea wind-powered electricity generation large diameter single pile foundation
In piling work, the requirement of pile sinking verticality is very high, generally within 2/1000ths.Therefore, the installation of offshore wind farm single-pile foundation,
It is generally necessary to special jack up wind turbine installation vessel or assistance platform of driving piles temporarily.But build a special jack up
Wind turbine installation vessel expense is too high, and drive piles temporarily assistance platform manufacture and mounting cost relative moderate, still, interim piling auxiliary
Platform due to that before each construction, need to accomplish fluently several auxiliary piles, then, then install temporary operating platform in advance, therefore, during operation
Between it is longer, it is less efficient；And due to treating pile sinking operation after the completion of, auxiliary pile and temporary operating platform must remove recycling, need
Special special boat especially dials stake, and difficulty of construction is larger, and risk is higher.It is existing in order to ensure the verticality of pile sinking operation
During interim assistance platform installation, leveling is needed, and leveling difficulty is big, the leveling activity duration is longer.And existing assistance platform is in itself
Leveling precision is not high, can not ensure high-precision large diameter single sunk pile operation.
Utility model content
The main purpose of the utility model is that overcoming disadvantages mentioned above of the existing technology, and a kind of movable type is provided and is beaten
Stake assistance platform under conditions of grouser is not played, using the suction sinker of suction anchor and jacking recycling function, not only avoids
It is cumbersome to play grouser and dial pile driving construction operation, it solves the problems, such as to be rapidly assembled and disassembled；Moreover, make full use of suction anchorage
The high-precision levelling function of plinth solves Large-diameter Steel sunk pile precision problem.
The purpose of this utility model is realized by following technical scheme：
A kind of mobile piling assistance platform, it is characterised in that：Including：Jacket, the suction mounted on jacket lower part
Anchor foundation is mounted on the piling assistance platform on jacket top using casing flange inserting and bolt connecting mode, is fixed on and beats
Pile gripper on stake assistance platform；Wherein, several tubulose lifting lugs are provided on jacket.
A several assistance platform suspension centres are provided on the piling assistance platform.
The pile gripper includes：For hold piling bar top tightly upper pile gripper arm, for hold piling bar lower part tightly lower armful
Stake device arm, leading truck and hydraulic device on piling assistance platform.
The beneficial effects of the utility model：The utility model due to the adoption of the above technical scheme, utilizes the suction of suction anchor
Sinker and jacking recycling function, not only avoid it is cumbersome play grouser and dial pile driving construction operation, solve Fast Installation and tear open
Problem is unloaded, reduces construction cost and construction risk；Moreover, make full use of high-precision levelling function and the pile holding of suction anchor foundation
Device accurate limiting straightening function solves Large-diameter Steel sunk pile precision problem, greatly improves construction efficiency；Meanwhile repeatable make
With.
