To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
The embodiment of the invention provides a kind of antidumping jack-up units.Fig. 1 is provided in an embodiment of the present invention a kind of anti-
Topple the structural schematic diagram of jack-up unit.Referring to Fig. 1, the antidumping jack-up unit include hull 10, multiple spud legs 20 with
And with the one-to-one inclined lift device 30 of each spud leg 20.Hull 10 is equipped with a pair of with each inclined lift device 30 1
The setting direction of the strip through-hole 11 answered, each strip through-hole 11 is consistent with the vertical direction of hull 10, each strip through-hole 11
Length direction it is consistent with the length direction of hull 10.The corresponding inclined lift of strip through-hole 11 is equipped in each strip through-hole 11
Device 30.
Wherein, the vertical direction of hull 10 refers to the direction from the top of hull 10 towards the lower part of hull 10, Huo Zhecong
Direction of the lower part of hull 10 towards the top of hull 10.The length direction of hull 10 refers to from the head of hull 10 towards hull
The direction of 10 tail portion, or from the tail portion of hull 10 towards the direction on the head of hull 10.
Fig. 2 is the structural schematic diagram of inclined lift device provided in an embodiment of the present invention.Referring to fig. 2, inclined lift device
30 include lifting structure 31 and bindiny mechanism 32, and bindiny mechanism 32 belongs to hull 10 and with bindiny mechanism 32 same respectively
The elevating mechanism 31 of inclined lift device 30 connects.
As shown in Figure 1, the elevating mechanism 31 close to the head of hull 10 makees the direction of ascending motion and the head from hull 10
Portion is acute angle towards the angle α between the direction of the tail portion of hull 10, and the work of elevating mechanism 31 close to the tail portion of hull 10 rises
The direction of movement and be acute angle from the tail portion of hull 10 towards the angle between the direction β on the head of hull 10.Elevating mechanism 31
