Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be understood that the orientation of the instructions such as term "upper", "lower", "left", "right"
Or position relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model and simplification is retouched
It states, does not indicate or imply the indicated device or element must have a particular orientation, with specific azimuth configuration and operation,
Therefore it should not be understood as limiting the present invention.
Referring to Fig. 1 to Fig. 4, the jack up hoistable platform described in this preferred embodiment includes main hull 1, several cranes
2 and several spud legs 3, in the present embodiment, the quantity of spud leg 3 is preferably one, and the spud leg 3 is along perpendicular to the main hull 1
The direction on surface penetrates through the main hull 1, and the spud leg 3 is equipped with several lifting gears 4, and the quantity of lifting gear 4 is preferred
It it is one, the crane 2 is connected by lifting gear 4 with the spud leg 3.
Based on the above structure, 3 structure of spud leg is that perforation main hull 1 is arranged, and crane 2 is by being arranged on spud leg 3
Lifting gear 4 power is provided, carry out upper and lower movement, disclosure satisfy that in crane 2 itself lifting work various hangs height；
1 structure of main hull and 2 structure separate design of crane, crane 2 is completely attached on spud leg 3, so risen in crane 2
When drop movement, main hull 1 still keeps swimming in the action on the water surface, i.e., when crane 2 carries out elevating movement, on spud leg 3
Lifting gear 4 needs to provide the support to crane 2, so as to greatly improve the efficiency of the lifting of crane 2, also reduces
Itself configuration to lifting gear 4, the especially requirement of lift capability.Spud leg 3 due to running through main hull 1 only needs to provide
To the support of crane 2 requirement, thus relative to existing jack-up unit need to have at least 3~4 quantity spud leg 3 and
Speech, the jack up hoistable platform at least can only be arranged a spud leg 3, greatly reduce the quantity of the configuration of spud leg 3, reduce lifting dress
Set 4 configurations, reduce by 4 a plurality of spud leg 3 of lifting gear in conjunction with debugging difficulty, so as to greatly reduce platform construction cost and
Operation cost, this has larger attraction in actual production and application so that the jack up hoistable platform has wide
Market prospects.
Wherein, crane 2 includes gantry body 21 and support plinth 22, and gantry body 21 is connected to support plinth 22
On, lifting gear 4 is set on the outer wall of spud leg 3, and support plinth 22 is connected with lifting gear 4, and lifting gear 4 can pass through
Driving support plinth 22 moves up and down and crane 2 is driven to move so that the lifting effect of crane 2 is relatively reliable；Spud leg 3 is
Through the support plinth 22 and the gantry body 21, i.e. support plinth 22 and gantry body 21 is set on spud leg 3,
Be conducive to improve support plinth 22 under the driving of lifting gear 4 along the smoothness of 3 up and down motion process of spud leg；Each lifting
Device 4 is spacedly distributed along the circumferential direction of the spud leg 3, can be that the support plinth 22 of crane 2 provides power evenly, protect
Demonstrate,prove the stationarity that crane 2 moves up and down.The power source of lifting gear 4 and the power source of crane 2 are lifted flat by jack up
Platform provides, so being equipped with flexible collapsible on the support plinth 22 of main deck or crane 2 of the needs around location hole 11
Fluid pressure line, crawler type electric wire store up cable bracket, make crane 2 support plinth 22 lift when still keep and hull power and control
The connection of system processed, and crane 2 is electrically connected with the control unit of the main hull 1 respectively with the power source of lifting gear 4, just
It is reliably provided in guarantee power.
In addition, the jack up hoistable platform further includes shoe 5, shoe 5 is fixedly connected on the bottom of spud leg 3, crane 2 with
The separate design of main hull 1 makes spud leg 3 only be solely subjected to the weight of crane 2, suffered when shoe 5 carries out pitching pile at this time
The weight of pressure and pressure compared to the full ship born required for existing jack up hoistable platform for it is smaller, be conducive to this
The pitching pile of jack up hoistable platform and pile pulling operation, improve the pitching pile of hoistable platform and the efficiency of pile pulling.If main hull 1 is equipped with
The dry location hole 11 for running through the main hull from top to bottom, spud leg 3 are set in location hole 11, and can be in location hole 11
Support plinth 22 and shoe 5 arrange that the width value of the support plinth 22 and the width value of the shoe 5 are respectively less than the positioning
The internal diameter in hole 11, the location hole 11 can run through for spud leg 3, facilitate the connection between spud leg 3 and main hull 1, and 5 pile pulling of shoe
After can collect to location hole 11, support plinth 22 can also be collected to being adjusted to the height of crane 2 in location hole 11
Minimum state ensures the stationarity of entire jack up hoistable platform when moving.The hole inner height of location hole 11 is more than bearing bottom
The sum of the height of seat 22 and shoe 5, i.e. support plinth 22 and shoe 5 can be during jack up hoistable platform move all
It is retracted in the location hole 11 on main hull 1, the effective resistance for reducing hoistable platform in moving process ensures hoistable platform
Safety in moving process.It needing to illustrate herein, in the present embodiment, the shape of location hole 11 can be circle,
Can also be the other structures such as rectangle or triangle, as long as can ensure that the perforation of shoe 5 is set in location hole 11.
It should be noted that in the present embodiment, crane 2 is using flange rotating disc type full-rotary crane, favorably
In being arranged to hang around stake, and wide coverage is lifted by crane, is more suitable for marine hoisting operation；The quantity of 1 upper Positioning holes 11 of main hull
It is one to use, i.e. 2 device of crane outfit is a set of, to meet the common requirements of marine hoisting operation, but at other
In embodiment, the selection of the type of crane 2 and the quantity of location hole 11 is not limited by the present embodiment, when can be according to reality
Needs, select the quantity of the type and location hole 11 of suitable crane 2.
