Running through between upper disk spring group and lower disk spring group has pull bar.
The utility model has advantages below compared with prior art：The utility model ring beam is rational in infrastructure, is easy to manufacture
Processing, component is convenient to install and maintain, and is applicable to the spud leg of the various types such as shell-and-plate, truss-like, greatlys save solid stake
Chamber inner space, the advantages that reducing dead load.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Label in figure：1- wedge brackets, 2- English truss formulas spud leg, 3- fixed sliders, 4- movable sliders, 5- hoist cylinders, 6- are fixed
Disk spring group, 10- pull bars under sliding block bolt, 7- movable sliders latch, the upper disk spring groups of 8-, 9-.
Embodiment：
, below will be to the utility model to make the purpose, technical scheme and advantage of the utility model embodiment clearer

Running through between groups of springs 9 has pull bar 10.The disk spring group and pull rod device, connection and reasonable arrangement, can effectively act as damping and
Cushioning effect, protection structure and lowering or hoisting gear；
The operation principle of lifting platform action of the present utility model：
Fixed slider latch insertion spud leg pin hole is kept first, and subsequent movable slider latch extracts spud leg pin hole, lifting oil
Cylinder shrinks a pitch, detects up to after hole position, and movable slider latch insertion spud leg pin hole is kept, and fixed slider latch extracts spud leg
Pin hole, hoist cylinder are extended one pitch of platform lifting；Then fixed slider latch again insertable into spud leg pin hole and is kept,
Movable slider latch extracts spud leg pin hole, and hoist cylinder shrinks a pitch, such perseveration, reaches lifting platform again
Effect.
The operation principle of the present utility model for declining platform action：
Fixed slider latch insertion spud leg pin hole is kept first, and subsequent movable slider latch extracts spud leg pin hole, lifting oil
Cylinder stretches out a pitch, detects up to after hole position, and movable slider latch insertion spud leg pin hole is kept, and fixed slider latch extracts spud leg
Pin hole, hoist cylinder shrinkage band moving platform decline a pitch；Then fixed slider latch again insertable into spud leg pin hole and is protected
Hold, movable slider latch extracts spud leg pin hole, and hoist cylinder stretches out a pitch, such perseveration, it is flat to reach decline again
The effect of platform.
Lowering or hoisting gear directly affects the peace of platform as the most critical part in marine jack-up unit, the quality of its performance
Entirely.Hydraulic pressure pin-type lifting device is entered in this utility model single step, and its ring beam is rational in infrastructure, be easy to manufacture process, disc spring, pull bar,
The components such as latch, hoist cylinder are convenient to install and maintain, and are applicable to the spud leg of the various types such as shell-and-plate, truss-like, significantly
Fixed pile chamber inner space is saved, the advantages that reducing dead load.
Finally it should be noted that：Although the utility model and its advantage are described in detail above it should be appreciated that
Various change can be carried out in the case of without departing from the spirit and scope of the present utility model being defined by the claims appended hereto
