Technical Field

[0001] This utility model relates to the technical field of drilling platform support bases, specifically a drilling platform support base. Background Technology

[0002] In the fields of marine resource development and marine engineering construction, drilling platforms are key equipment for seabed oil and gas exploration, extraction, and marine scientific research operations. As the core support structure of the drilling platform, the support base plays a crucial role in safely transferring the platform's own weight, the drilling equipment load, and dynamic loads generated during operations (such as drill bit impact force, wave impact force, and wind force) to the seabed foundation. Its stability and reliability are directly related to the safety and efficiency of the entire drilling operation and the service life of the platform.

[0003] When using a support base, for the installation location of large equipment, the support base is supported only by its own strength. However, during the manufacturing of the support base, it is usually welded and assembled according to the estimated load. But in actual operation, overload situations may be encountered, such as the impact load when the drill gets stuck, which can easily affect the stability of the support base.

[0004] Therefore, a drilling platform support base is proposed to solve the problems mentioned above. Utility Model Content

The support mechanism includes a support seat 3, a base plate 4, mounting holes 5, series holes 6, a fixing groove 7, a first support block 8, a first inclined surface 9, a second support block 10, and a second inclined surface 11. The support seat 3 is located at the bottom of the steel structure support base body 1, and the base plate 4 is fixedly connected to the side of the support seat 3. The mounting holes 5 are opened at the top of the base plate 4, the series holes 6 are opened at the top of the base plate 4, the fixing groove 7 is opened inside the base plate 4, the first support block 8 is located inside the fixing groove 7, the first inclined surface 9 is opened at the bottom of the first support block 8, the second support block 10 is located at the bottom of the first support block 8, and the second inclined surface 11 is located at the top of the second support block 10.

[0020] At the bottom of the location where a large piece of equipment is installed on the steel structure support base body 1, a support seat 3 is added. The second support block 10 is pushed to slide by the hydraulic cylinder 18. With the guidance of the first inclined surface 9 and the second inclined surface 11, the first support block 8 is lifted upward. The top of the first support block 8 contacts the bottom of the steel structure support base body 1, providing auxiliary support for the steel structure support base body 1. The first support block 8 and the second support block 10 can be made of pine wood, which has a buffering and energy absorption effect and can better protect the steel structure support base body 1. The matching setting of the limiting block 12 and the limiting groove 13 can prevent the second support block 10 from shifting when pushed.

[0021] Please see Figure 1 - Figure 4 The outer walls of the first support block 8 and the second support block 10 are in contact with the interior of the fixing groove 7. The bottom of the second support block 10 is fixedly connected to the limiting block 12, and the interior of the support base 3 is provided with a limiting groove 13.

[0022] Please see Figure 1 - Figure 3 The limiting block 12 is slidably connected inside the limiting groove 13. The inner wall of the limiting groove 13 is in contact with the outer wall of the limiting block 12. The limiting block 12 has a T-shaped structure.

[0023] Please see Figure 3 - Figure 4 The transmission mechanism includes a side bracket 17, a hydraulic cylinder 18, an abutment component 19, a protrusion 20, and a connecting groove 21. The side bracket 17 is located on one side of the support base 3. The hydraulic cylinder 18 is fixedly connected to the outside of the side bracket 17. The abutment component 19 is fixedly connected to the output end of the hydraulic cylinder 18. The protrusion 20 is fixedly connected to the outside of the support base 3. The connecting groove 21 is opened on the top of the protrusion 20. The hydraulic cylinder 18 is equipped with a hydraulic lock.

[0024] The hydraulic cylinder 18 is mounted on one side of the support base 3 via the side bracket 17. The protrusion 20 is fixed to the side bracket 17 by bolts. The hydraulic cylinder 18 pushes the metal plate 14 against the contact component 19, thereby driving the second support block 10 to slide stably. The setting of the insert plate 15 slidingly inserted into the slot 16 can prevent the metal plate 14 from shifting, thus achieving a more stable support effect for the first support block 8 and the second support block 10.

[0025] Please see Figure 3 - Figure 4The inner wall of the connecting groove 21 is in contact with the outer wall of the end of the side bracket 17. A support column is fixedly connected to the bottom of the side bracket 17. A metal plate 14 is fixedly connected to one side of the second support block 10. An insert plate 15 is fixedly connected to the bottom of the metal plate 14. A slot 16 is provided inside the support base 3. The inner wall of the slot 16 is in contact with the outer wall of the insert plate 15. The insert plate 15 is slidably inserted into the inside of the slot 16.

[0026] To avoid pressure concentration, the contact assembly 19 includes a first contact plate 22, a crossbar 23, a second contact plate 24, and a support frame 25. The first contact plate 22 is fixedly connected to the output end of the hydraulic cylinder 18, the crossbar 23 is fixedly connected to the outside of the first contact plate 22, the second contact plate 24 is fixedly connected to one end of the crossbar 23, and the support frame 25 is fixedly connected to the outside of the first contact plate 22.

[0027] By setting the first contact plate 22 and the second contact plate 24, stress concentration can be avoided when pushing, so that the second support block 10 is subjected to force more evenly, and the second support block 10 is not damaged due to excessive local pressure. The triangular structure of the support frame 25 can play a supporting role, improve the overall strength of the contact component 19, prevent the crossbar 23 from breaking, and play a more stable supporting role.

[0028] Please see Figure 1 - Figure 4 One end of the support frame 25 is fixedly connected to the second contact plate 24, and the support frame 25 has a triangular structure.

[0029] The working principle of the above embodiments is as follows: At the bottom of the location where a large piece of equipment is installed on the steel structure support base body 1, a support seat 3 is added. The second support block 10 is pushed to slide by the hydraulic cylinder 18. With the guidance of the first inclined surface 9 and the second inclined surface 11, the first support block 8 is lifted upward. The top of the first support block 8 contacts the bottom of the steel structure support base body 1 to provide auxiliary support for the steel structure support base body 1. The first support block 8 and the second support block 10 can be made of pine wood, which has a buffering and energy absorption effect and can better protect the steel structure support base body 1. The matching setting of the limiting block 12 and the limiting groove 13 can prevent the second support block 10 from shifting when pushed. The hydraulic cylinder 18 is mounted on one side of the support base 3 via the side bracket 17. The protrusion 20 is fixed to the side bracket 17 by bolts. The hydraulic cylinder 18 pushes the metal plate 14 against the contact component 19, thereby driving the second support block 10 to slide stably. The setting of the insert plate 15 slidingly inserted into the slot 16 can prevent the metal plate 14 from shifting, thus achieving a more stable support effect for the first support block 8 and the second support block 10. By setting the first contact plate 22 and the second contact plate 24, stress concentration can be avoided when pushing, so that the second support block 10 is subjected to force more evenly, and the second support block 10 is not damaged due to excessive local pressure. The triangular structure of the support frame 25 can play a supporting role, improve the overall strength of the contact component 19, prevent the crossbar 23 from breaking, and play a more stable supporting role.
