Problems solved by technology
This solution has the following problems: 1) The pile holder is placed inside the closed welded structure, which cannot be conveniently installed, observed, and maintained. Once the welded structure is disassembled, the original structure must be destroyed and cannot be reused; 2) The pile holder The overall design idea creates the defect of taking up a lot of space, and the external dimension can reach more than twice the diameter of the pile legs, which is not conducive to the effective use of the deck area of the platform; 3) The stroke position of the rotating ring beam can only be fully extended or Fully retracted to ensure that once the cylinder or hydraulic system fails, causing the piston rod to not be fully extended or retracted, and the outside cannot know the abnormal situation, if the lifting cylinder is activated, unpredictable or even catastrophic accidents will occur

Embodiment Construction
[0016] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present invention. All similar structures and similar changes of the present invention should be included in the scope of protection of the present invention. The commas in all indicate the relationship between and.
[0017] Such as Figure 1-Figure 3 As shown, a ring pin type offshore platform lifting device provided by the embodiment of the present invention includes a leg 1 and at least one lifting cylinder 4. The leg 1 is sleeved with an upper and a lower one that can slide up and down along the leg. ring beams 3, one of which is affixed to the cylinder body of each lifting cylinder 4, and the other ring beam 3 is affixed to the piston rod of each lifting cylinder 4;
[0018] It is characterized in that: the outer wall of the pile leg 1 is fixed with a plurality of vertical rails 2, a...

The invention discloses a battle pin type ocean platform lifting device and relates to the technical field of ocean engineering equipment. The technical problems that an existing device is large in occupied space, inconvenient to maintain and low in safety are solved. The device comprises a pile leg, a lifting oil cylinder, an upper ring beam and a lower ring beam, wherein the upper ring beam and the lower ring beam are arranged on the pile leg in a sleeving manner. A cylinder body of the lifting oil cylinder is fixedly connected with one of the two ring beams, and a piston rod of the lifting oil cylinder is fixedly connected with the other one of the two ring beams. A plurality of vertical rail bars are fixed to the outer wall of the pile leg. Annular battle pins capable of rotating and battle pin oil cylinders used for driving the battle pins to rotate are installed on the ring beams. A plurality of pin blocks are fixed to the inner side walls of the battle pins. Each rail bar is provided with a plurality of pin grooves for the pin blocks on the battle pins to come in and go out. The pin grooves in the rail bars are formed at equal intervals from top to bottom. The battle pin type ocean platform lifting device is suitable for an ocean platform lifting system.
Description
technical field [0001] The invention relates to the technology of offshore equipment, in particular to the technology of a ring-pin type offshore platform lifting device. Background technique [0002] With the deepening development and utilization of marine resources by human beings, the application of jack-up ocean platforms is becoming more and more extensive. The natural environment on the sea is unpredictable, and the locking device of the pile legs is an indispensable force-bearing part under all working conditions of the platform, which is extremely important to the stability, safety and reliability of the platform. [0003] For the offshore platform that adopts the step-by-step lifting of shell legs, the locking device mainly has two methods: bolt and wedge. The bolt-type locking method has a complex stress structure and takes up a lot of space; and holes need to be opened on the legs, which will weaken the strength and rigidity of the legs. The wedge-type locking d...
