[0001] The utility model relates to the technical field of marine pile foundations, and particularly relates to a pile-pulling self-elevating marine platform pile shoe. Background Technique

[0002] As a kind of marine engineering machinery, a marine platform is used for operations such as offshore oil exploitation and structure hoisting, and mainly consists of a platform main body, pile legs, pile shoes, and lifting mechanisms. In the working state, the platform main body is supported above the sea level by the pile legs and pile shoes, and the pile legs and pile shoes penetrate deep into the seabed to bear the pressure of the entire marine platform.

[0003] For example, a marine platform pile shoe structure with the publication number of CN220503889U includes a pile shoe body, and the pile shoe body is connected to the pile legs on the marine platform. The interior of the pile shoe body has an accommodation space, and a plurality of auxiliary platforms are slidably arranged in the accommodation space, and a telescopic part is arranged in the space. The telescopic part is used to simultaneously push the plurality of auxiliary platforms out of the accommodation space or simultaneously retract the plurality of auxiliary platforms into the accommodation space. A plurality of strengthening parts for supporting the auxiliary platforms are also arranged between the pile shoe body and the pile legs. Through the cooperation of relevant structures, the utility model realizes that by setting one telescopic part, a plurality of auxiliary platforms can be simultaneously pushed out or retracted into the accommodation space, avoiding the use of a plurality of telescopic parts to drive a plurality of auxiliary platforms, reducing the use cost, and at the same time reducing the installation and subsequent maintenance and replacement time, and improving the work efficiency.

[0004] The above technical solution has some problems in practical applications. Since the marine pile foundation is greatly affected by the ocean during use, it is particularly crucial to ensure the stability of the pile shoe after insertion, especially the anti-offset ability after being affected by ocean currents. However, the above technical solution fails to improve the anti-offset ability of the pile shoe.

[0005] Therefore, it is very necessary to invent a pile-pulling self-elevating marine platform pile shoe to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a Figures 1-4 shown pile pulling and self-elevating offshore platform pile shoe, including a pile shoe body 1. A pile leg 2 is fixedly arranged at the top end of the pile shoe body 1. A plurality of grooves 3 are circumferentially formed on the outer side wall of the pile shoe body 1. A movable arm 4 is movably arranged inside the groove 3 through a pin shaft. One end of the movable arm 4 is movably arranged with a support plate 5 through a pin shaft.

[0023] Specifically, a transmission arm 6 is movably arranged in the middle of the movable arm 4 through a pin shaft. A fixing frame 7 is fixedly arranged in the middle of the upper surface of the pile shoe body 1. A transmission seat 8 is arranged inside the fixing frame 7. The tops of multiple transmission arms 6 are movably connected to the outer side wall of the transmission seat 8 through pin shafts. The top of the fixing frame 7 is fixedly provided with a first hydraulic rod 9, and the bottom end of the first hydraulic rod 9 is fixedly connected to the top end of the transmission seat 8. The first hydraulic rod 9 drives the transmission seat 8 to move. The transmission seat 8 drives the movable arm 4 to move through the transmission arm 6, so that the movable arm 4 rotates around the pin shaft. The movable arm 4 drives the support plate 5 to move, so that the support plate 5 fits with the seabed. At this time, the support plate 5 can play an auxiliary supporting role for the pile shoe body 1;

[0024] More specifically, an insertion end 10 is fixedly arranged in the middle of the lower surface of the pile shoe body 1, and the insertion end 10 is arranged in a conical structure. The insertion end 10 is arranged in a hollow structure, and a plurality of fixing pipes 11 are arranged around the outer side wall of the insertion end 10. A positioning rod 12 is inserted into the fixing pipe 11, and one end of the positioning rod 12 is arranged inside the insertion end 10. The positioning rod 12 slides in the fixing pipe 11, so that one end of the positioning rod 12 is inserted into the seabed soil layer to play an auxiliary supporting role;

[0025] And, a sliding rod 13 is fixedly arranged at the top end of the positioning rod 12. An activity seat 14 is arranged inside the insertion end 10. A plurality of sliding rails 15 are arranged around the outer side wall of the activity seat 14, and the sliding rails 15 correspond to the sliding rod 13. A second hydraulic rod 16 is fixedly arranged at the bottom end of the activity seat 14, and the second hydraulic rod 16 is fixedly arranged at the bottom end of the inner side wall of the insertion end 10. The second hydraulic rod 16 can drive the sliding rail 15 to move through the activity seat 14, and the sliding rail 15 can squeeze the sliding rod 13 to realize the adjustment of the position of the positioning rod 12;

[0026] Moreover, a conical part 17 is arranged at the bottom end of the positioning rod 12. The arrangement of the conical part 17 ensures that the positioning rod 12 can be inserted into the seabed soil layer. Anti-slip grooves 18 with a serrated structure are arranged on the outer side wall of the support plate 5. The arrangement of the anti-slip grooves 18 enables the support plate 5 to be inserted into the surface layer of the seabed soil layer during the outward movement process to ensure its support effect.

[0027] The working principle of the utility model:

[0028] When the device is in use, the pile shoe body 1 and the pile leg 2 can be released downward on the offshore platform, so that the insertion end 10 at the bottom of the pile shoe body 1 is inserted into the seabed. After the insertion end 10 is inserted into the seabed, the first hydraulic rod 9 drives the transmission seat 8 to move, and the transmission seat 8 drives the movable arm 4 to move through the transmission arm 6, so that the movable arm 4 rotates around the pin shaft. The movable arm 4 drives the support plate 5 to move, so that the support plate 5 fits with the seabed. At this time, the support plate 5 can play an auxiliary supporting role for the pile shoe body 1. At the same time, after the insertion end 10 is inserted into the seabed soil layer, the second hydraulic rod 16 drives the movable seat 14 to move, and the movable seat 14 squeezes the sliding rod 13 through the slide rail 15, so that the sliding rod 13 drives the positioning rod 12 to move. The positioning rod 12 slides in the fixed pipe 11, so that the conical part 17 at one end of the positioning rod 12 is inserted into the seabed soil layer to play an auxiliary supporting role.
