Problems solved by technology
[0002] Offshore platforms include ship splints, artificial floating islands, offshore operating platforms, etc. At present, they are mostly positioned by anchoring, but this method of positioning is inaccurate and unstable, and will swing and drift under the action of ocean currents, which is not conducive to operations on the platform; Other shallow sea piling platforms mostly use one-way and continuous piling operations. Not only are the equipment numerous and bulky, but the operating equipment is at a high position and the overall center of gravity is high, which is not conducive to the stability and safety of navigation. The resistance to movement is large, and the piles The positioning process is complicated, the operation is inconvenient, and the positioning verticality and stability are poor

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] like Figure 3 to Figure 10 As shown, the pile-pressing type offshore platform positioning device of this embodiment includes a platform 1, three sets of pile-pressing devices 2 arranged on the platform; The positioning piles 4 of the platform 1, the bottoms of the positioning piles 4 are all pointed bottoms, the lower end side of the mounting seat 3 is hinged with the platform 1 through two hinge shafts 5, the cylinders of the two luffing cylinders 6 are hinged with the platform 1, and the luffing cylinders are hinged. The piston rod 7 of 6 is connected with one side of the mounting seat 3, the two ends of the other side of the mounting seat 3 are provided with pin holes, and two pin seats 8 with pin holes and two locking oil cylinders are fixed on the platform 1 9. The piston rod of the locking oil cylinder 9 is fixedly connected with a movable pin ...

The invention discloses a pile pressing type offshore platform positioning device. The pile pressing type offshore platform positioning device comprises a platform and more than three sets of pile pressing devices; the pile pressing devices comprise mounting seats and locating piles; one sides of the lower ends of the mounting seats are hinged to the platform; variable amplitude oil cylinders arehinged to the platform and one sides of the mounting seats; pin holes are formed in the other sides of the mounting seats; movable bolts are arranged on the platform; a plurality of fixing pile clamping oil cylinders and pile pressing oil cylinders are fixedly arranged on the mounting seats; clamping blocks are fixedly connected to piston rods of the fixing pile clamping oil cylinders; clamping frames are arranged in the mounting seats; a plurality of mobile pile clamping oil cylinders are fixedly arranged in the pile clamping frames; mobile clamping blocks are fixedly connected to piston rodsof the mobile pile clamping oil cylinders; and the pile pressing oil cylinders are fixedly connected to the pile clamping frames. The pile pressing type offshore platform positioning device has the advantages of less equipment, small volume and low gravity center; the sailing stability and safety can be enhanced, the moving resistance is small, the positioning procedure is convenient to operate,and the positioning perpendicularity and stability are good.
Description
technical field [0001] The invention relates to a positioning device for an offshore platform, in particular to a pile-pressed offshore platform positioning device. Background technique [0002] Offshore platforms include ship splints, artificial floating islands, marine operation platforms, etc. At present, they are mostly positioned by anchoring, but this method is inaccurate and unstable, and will swing and drift under the action of ocean currents, which is not conducive to the operation on the platform; Other shallow sea piling platforms mostly use one-way and continuous piling operations, which not only have many equipment and large volumes, but also the operating equipment is in a high position and the overall center of gravity is high, which is not conducive to the stability and safety of navigation, the resistance to movement is large, and the piles The positioning process is complicated, the operation is inconvenient, and the positioning verticality and stability ar...
