Description
Technical field
The present invention relates to ocean platform jack up lowering or hoisting gear, more particularly to a kind of truss-like hydraulic bolt lowering or hoisting gear.
Background technology
Self-elevating ocean platform pile leg structure mainly has two kinds of case type and truss-like, and case type application is wider.Phase
For truss framed leg, the structure of case type is simple, is easy to manufacture to process, but big by the Area comparison of such environmental effects, and
And it can only be worked in shallow sea.Truss-like can be in more than 60m deep ocean work, therefore truss-like often uses deep ocean work installation ship
Or on offshore drilling platformses and be pinion and-rack.General truss formula spud leg is pinion and-rack structure, work
It is unstable to make performance, potential safety hazard be present.
The content of the invention
The invention aims to overcome the shortcomings of the above, there is provided a kind of simple in construction, safe and reliable, easy to use
Truss-like hydraulic bolt lowering or hoisting gear.
The purpose of the present invention is achieved through the following technical solutions：A kind of truss-like hydraulic bolt lowering or hoisting gear, including it is solid
Pile frame, wedge bracket are provided with English truss formula spud leg, three main chord tubes, every main string are evenly distributed with English truss formula spud leg
The both sides of pipe are provided with directive slide track, and top shoe and sliding block are cased with directive slide track, and top shoe is provided with upper pin hole, sliding block
Lower bearing pin hole is provided with, the bottom of top shoe is inserted with latch, and the bottom of sliding block is inserted with lower latch, and the top of top shoe is provided with
Upper strata oil cylinder, is provided with upper connection otic placode between upper strata oil cylinder and wedge bracket, the top of sliding block is provided with lower floor's oil cylinder, lower floor's oil cylinder
Lower connection otic placode is provided between wedge bracket.
Further improvement of the present invention is：The top of top shoe is provided with two upper strata oil cylinders, two upper strata oil cylinder difference
It is placed in the both sides of wedge bracket.
Further improvement of the present invention is：The top of sliding block is provided with Liang Ge lower floors oil cylinder, Liang Ge lower floors oil cylinder difference
It is placed in wedge bracket both sides.
The present invention has advantages below compared with prior art：The present invention effectively reduces spud leg deadweight, avoids current pair
Pile body impacts, and service behaviour is steady, under work and the various states of inoperative, has a variety of safety precautions, when one
When root latch fails, redistributing for power can be carried out using hydraulic system, ensure that platform is made in descending operation and offshore drilling
Industry safety.The present invention compensate for due to the longitudinal and transverse problem of inclining of hull caused by sea bed injustice under platform pitching pile holding state, available
Support is adjusted in upper and lower sliding block oil cylinder pressurize.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention；
Label in figure：1- wedge brackets, 2- English truss formulas spud leg, 3- directive slide tracks, 4- top shoes, 5- sliding blocks, on 6-
Latch, 10- upper stratas oil cylinder, the upper connection otic placodes of 11-, 12- lower floors oil cylinder, 13- under pin shaft hole, 7- lower bearing pins hole, the upper latches of 8-, 9-
Lower connection otic placode.
Embodiment：
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended to limit the scope of the present invention..
As Fig. 1 shows a kind of a kind of embodiment of truss-like hydraulic bolt lowering or hoisting gear of the present invention, including wedge bracket
1, wedge bracket 1 is provided with English truss formula spud leg 2, and three main chord tubes, every main string are evenly distributed with English truss formula spud leg 2
The both sides of pipe are provided with directive slide track 3, and top shoe 4 and sliding block 5 are cased with directive slide track 3, and top shoe 4 is provided with upper pin hole 6,
Sliding block 5 is provided with lower bearing pin hole 7, and the bottom of top shoe 4 is inserted with latch 8, and the bottom of sliding block 5 is inserted with lower latch 9, upper cunning
The top of block 4 is provided with upper strata oil cylinder 10, and upper strata oil cylinder 10 and lower floor's oil cylinder 12 can be provided with two, two upper strata oil cylinders 10 and two
Individual lower floor's oil cylinder 12 is respectively placed in the both sides of wedge bracket 1；Upper connection otic placode 11 is provided between upper strata oil cylinder 10 and wedge bracket 1, under
The top of sliding block 5 is provided with lower floor's oil cylinder 12, and lower connection otic placode 13 is provided between lower floor's oil cylinder 12 and wedge bracket 1.
Embodiment one
Top shoe is hinged by six oil cylinders with hull wedge bracket, and sliding block is hinged by six oil cylinders with wedge bracket, upper,
Six sets of bolt devices are respectively provided with sliding block.When peaceful, upper cylinder is in shortest route state, and latch inserts spud leg hole,
Lower latch extracts spud leg hole, and lift cylinder is retracted to shortest route, and inserts latch, and upper latch is extracted, sliding block lifting oil
Cylinder extends, and platform is by raising, until after a pitch, upper latch insertion, lower latch is extracted, and oil cylinder is retracted to shortest route, such as
Above-mentioned action reaches the purpose of peaceful repeatedly for this；When dropping platform, in lower latch insertion spud leg hole, upper latch extracts spud leg hole,
Oil cylinder drives sliding block to be retracted to a spud leg pitch, and platform does down maneuver, upper latch insertion spud leg hole, and lower latch extracts stake
Leg holes, oil cylinder are extended to a spud leg pitch, lower latch insertion spud leg hole, upper latch extraction spud leg hole, above-mentioned action repeatedly,
Complete the purpose that platform declines；Piling can be completed by upper and lower oil cylinder synchronization of jacking up, contraction when the pre- ballast of storm, pile pulling and pulled out
Stake.
Embodiment two
Top shoe is hinged by six oil cylinders with hull wedge bracket, and sliding block is hinged by six oil cylinders with wedge bracket, upper,
Six sets of bolt devices are respectively provided with sliding block.When preparing to put peaceful of stake, upper and lower oil cylinder be in stretching state, latch holding
Insert in spud leg hole, during action, upper latch is extracted, and oil cylinder zero load bounces back to shortest route, is stretched out with oil cylinder at present, is passed through latch
Load is transmitted and transfers spud leg, until stretching out most long status, now upper latch insertion, lower latch are extracted, and upper cylinder drives spud leg
A pitch is covered as extending action, covers a pitch as retract action with oil cylinder zero load at present, so above-mentioned action repeatedly
Reach the peaceful purpose continuously lifted；When dropping platform, action is opposite.
The present invention effectively reduce spud leg deadweight, avoid current from impacting pile body, service behaviour is steady, work and
Under the various states of inoperative, there are a variety of safety precautions, when a latch fails, power can be carried out using hydraulic system
Redistribute, ensure platform descending operation and Offshore Operation safety.The present invention compensate for platform pitching pile holding state
Under due to the longitudinal and transverse problem of inclining of hull caused by sea bed injustice, support is adjusted using upper and lower sliding block oil cylinder pressurize.
