As Figure 1-Figure 2, a kind of ocean platform truss-like heavy haul and rapid jacking system that this utility model first embodiment is provided, including in many piles lower limb 1(figure, a pile lower limb is only shown), equipped with lowering or hoisting gear on described spud leg 1, it is characterised in that:
Described spud leg 1 is the polygonal truss spud leg being respectively fixed with a vertical chord member 11 in each corner, and all offers the multiple pin-and-holes 12 being spaced laying the most successively on the every chord member 11 of spud leg 1;
Described lowering or hoisting gear includes the annular guide holder 2 being nested with on spud leg 1 in clearance fit mode, and the most each power unit;
Each power unit includes multiple power slide block 3 that can slide up and down, and for the multiple lift cylinders 4 driving each power slide block 3 in this unit to slide up and down, each power slide block 3 in same unit is laid around spud leg symmetry, and the most affixed with the piston rod of each lift cylinder 4 in this unit;
Be equipped with on each power slide block 3 coming in and going out the latch 6 of the pin-and-hole 12 on spud leg, and for driving latch 6 to come in and go out the plugging pin oil cylinder 5 of the pin-and-hole 12 on spud leg.
In this utility model first embodiment, slide opening is offered on described power slide block 3, described latch 6 is arranged in slide opening with sliding matching mode, latch 6 is parallel to each other and affixed with the piston rod of plugging pin oil cylinder 5, and the direction that the retracted orientation of the piston rod of plugging pin oil cylinder 5 inserts the pin-and-hole 12 on spud leg with latch 6 is consistent, the piston rod of latch and plugging pin oil cylinder be arranged in parallel and avoids plugging pin oil cylinder with latch layout on the same axis, can reduce level to size.
In this utility model first embodiment, the chord member 11 in described each corner of spud leg 1 is square chord member, and on chord member 11, offer vertical direction recess, it is formed with guiding projection on described power slide block 3, and the guiding projection on each power slide block is respectively clamped into the direction recess on each chord member with sliding matching mode, make each power slide block can direction recess along each chord member vertically slidable, and each power slide block is the most mutually locked in level with each chord member.
The working method of this utility model first embodiment is as follows:
For ease of describing, below by upper for each lift cylinder in upper power unit lift cylinder, by the most lower for each lift cylinder in lower power unit lift cylinder, each power slide block in upper power unit is referred to as top shoe, each power slide block in lower power unit is referred to as sliding block;
During use, by affixed with ocean platform for the guide holder of the lowering or hoisting gear on each spud leg, in an initial condition, the pin-and-hole that latch on each power slide block is all inserted on spud leg, on each, the piston rod of lift cylinder is all in the state of stretching out, the piston rod of each lower lift cylinder is all in retracted mode, and the latch on the most each power slide block is all in loaded-up condition;
When needing to order about ocean platform rising, the action step of the lowering or hoisting gear on each spud leg is as follows:
1) plugging pin oil cylinder on each top shoe drives the latch on each top shoe to extract from the pin-and-hole of spud leg so that each top shoe unlocks with spud leg;
2) piston rod of each lower lift cylinder synchronizes to stretch out stroke, now each sliding block is fixed with spud leg by latch, thus by each lower lift cylinder by ocean platform upwards jacking, the most each upper lift cylinder synchronizes to make retraction stroke, order about each top shoe upward sliding to after one group of pin-and-hole of top, plugging pin oil cylinder on each top shoe drives the latch on each top shoe to insert this group pin-and-hole so that each top shoe locks (during this, each lower lift cylinder is at lasting jacking ocean platform) with spud leg;
3) plugging pin oil cylinder on each sliding block drives the latch on each sliding block to extract from the pin-and-hole of spud leg so that each sliding block unlocks with spud leg;
4) piston rod of each upper lift cylinder synchronizes to stretch out stroke, now each top shoe is fixed with spud leg by latch, thus by each upper lift cylinder by ocean platform upwards jacking, the most each lower lift cylinder synchronizes to make retraction stroke, order about each sliding block upward sliding to after one group of pin-and-hole of top, plugging pin oil cylinder on each sliding block drives the latch on each sliding block to insert this group pin-and-hole so that each sliding block locks (during this, each upper lift cylinder is at lasting jacking ocean platform) with spud leg;
5) reciprocal execution step 1 is to step 4 so that lower lift cylinder group and upper lift cylinder group jacking ocean platform alternately, and can order about ocean platform lasting rise to required height.
Be similar to, utilize lower lift cylinder group and the upper lift cylinder group jacking ocean platform that orders about alternately to decline, can order about ocean platform lasting drop to required height.
This utility model the second embodiment is with the difference of first embodiment: in the second embodiment, each corner chord member of spud leg is T-shaped chord member, it is formed with vertical direction recess on described power slide block, and the T-shaped chord member in each corner of spud leg is respectively clamped into the direction recess on each power slide block with sliding matching mode, make each power slide block can be vertically slidable along each chord member, and each power slide block is the most mutually locked in level with each chord member, slide opening is offered on power slide block in second embodiment, described latch is arranged in slide opening with sliding matching mode, latch is the most affixed with the piston rod of plugging pin oil cylinder.
The working method of this utility model the second embodiment is similar with first embodiment.
