The end portion of the pile shoe is of a ball-arc-shaped structure, and a plurality of protruding portions are arranged on the outer surface of a ball arc. The utility model further provides the offshore work platform. According to the pile leg and the offshore work platform, the meshing effect of the pile shoe and the seabed is improved, the capacity that the offshore work platform resists horizontal load is improved and safety and reliability of offshore construction operation of ship bodies are improved.
Description
Technical field
The utility model relates to heavy industry field, ocean, particularly a kind of spud leg and offshore work platform.
Background technology
Offshore work platform is a kind of marine mobile working platform for the water project construction.Location and support when spud leg is at sea constructed for offshore work platform keep the offshore work platform operation stable.Offshore work platform props up immediately at more smooth sea bed, does not generally need to do how many particular processing for spud leg.But, when the steeper gradient appears in the basement rock of sea bed, if use general spud leg location, the spud leg slippage of offshore work platform will appear, sometimes even the major accident that whole platform topples can take place.
At present, the spud leg of offshore work platform and the general vertical setting of boats and ships main body.The shoe of spud leg lower end is generally the plane and arranges, and is bigger with the contact area of sea bed, practical on softer relatively sea bed, but shoe can't be inserted sea bed when sea bed is hard, and platform or workboat will be difficult to fixedly positioning.If spud leg is not established shoe, when during lifting, then can there be the risk of toppling in platform or workboat on rough sea bed; And owing to environmental load or self operation produce bigger horizontal torque, the vertical setting of spud leg can't be satisfied its requirement.
The utility model content
In view of this, the utility model proposes a kind of spud leg and offshore work platform, keep stable problem at sea during construction operation to solve offshore work platform.
On the one hand, the utility model provides a kind of spud leg, and spud leg is used for keeping the offshore work platform operation stable, comprise pile body and shoe, shoe is fixedly connected on the lower end of pile body, and the end of shoe is the spherical arc shape structure, and the external surface of ball arc is provided with a plurality of lug bosses.
Further, lug boss is zigzag structure.
Further, pile body is provided with a plurality of pin holes.
A kind of offshore work platform also is provided on the other hand, has comprised spud leg and boats and ships main body that at least one is above-mentioned, spud leg is obliquely installed on the boats and ships main body.
Further, spud leg comprises four, and four spud legs are arranged in the boats and ships main body left and right sides, is positioned at two spud legs in boats and ships main body left side to boats and ships main body left side, and two spud legs that are positioned at boats and ships main body right side tilt to boats and ships main body right side.
Further, comprise that also adjusting device is installed on the boats and ships main body for driving the adjusting device that spud leg oscilaltion and/or angle of inclination are regulated.
Further, adjusting device is hydraulic jack or hydraulic motor.
A kind of spud leg and offshore work platform beneficial effect that the utility model provides are:
One, the spherical arc shape structure is adopted in shoe, and the external surface of spherical arc shape designs the zigzag convex-concave surface, improves the interlock effect of shoe and sea bed, improves the ability of the opposing horizontal load of offshore work platform; Keep the offshore construction job safety of boats and ships main body stable.
They are two years old, the left side spud leg tilts to boats and ships main body left surface, the right side spud leg tilts to boats and ships main body right side, adopt four spud legs that tilt to arrange, and angle of inclination and oscilaltion highly can be regulated by adjusting device, increase the ability of the anti-horizontal torsion load of offshore work platform and environmental load.
Description of drawings
The accompanying drawing that constitutes a part of the present utility model is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is offshore work platform front view of the present utility model;
Fig. 2 is the lateral view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is that the A of Fig. 1 is to zoomed-in view.
The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figures 1 to 4, a kind of offshore work platform comprises four spud legs 20 and boats and ships main body 1, adjusting device 3, four spud legs 20 are arranged in boats and ships main body 1 left and right sides, be positioned at two spud legs 20 in boats and ships main body 1 left side to boats and ships main body 1 left side, two spud legs 20 that are positioned at boats and ships main body 1 right side tilt to boats and ships main body 1 right side.Adjusting device 3 is used for driving four spud legs 20 along 1 oscilaltion of boats and ships main body and/or regulates four spud leg 20 angles of inclination.Adjusting device 3 is hydraulic jack or hydraulic motor, and hydraulic jack and hydraulic motor drive four spud legs 20 along 1 oscilaltion of boats and ships main body and/or regulate four spud leg 20 angles of inclination by mechanism.
As Fig. 2 and shown in Figure 4, spud leg 20 comprises pile body 200 and shoe 201, and shoe 201 is fixedly connected on the lower end of pile body 200, and the cross section of pile body 200 is circular configuration, maybe can adopt square or prismatic structure; The end of shoe 201 is hemispherical dome structure, also can adopt spherical arc shape structures such as 1/3 sphere, 2/3 sphere, and the external surface of ball arc is provided with a plurality of lug bosses 2010.Lug boss 2010 is zigzag structure, also can adopt the lug boss 2010 of other type.Pile body 200 is provided with a plurality of pin holes 2000.When pile body 200 is elevated to a certain height, scurry to pin hole 2000 by latch, pile body 200 is positioned at boats and ships main body 1 a certain height and position.
