Description

Technical Field

[0001] This utility model belongs to the technical field of drilling platform bases, and in particular relates to a shockproof fixing base for drilling platforms. Background Technology

[0002] The fixed base of a drilling platform refers to the structural foundation used to support and stabilize the entire drilling platform. It is usually located on the seabed or land, bearing the weight of the platform and ensuring its stability during drilling. The purpose of the fixed base design is to resist wind, waves, tidal changes and other external forces in the marine environment. The fixed base can adopt different design methods, such as monopile, jacket foundation or multi-pile foundation, the specific choice depends on the water depth, seabed geological conditions and drilling requirements.

[0003] Existing fixed bases for drilling platforms still present some problems during use. For example, when the platform is set up on the sea or land, the forces of waves and the vibrations of drilling equipment may affect the platform. These external forces are transmitted to the connection between the platform base and the foundation through the platform base. When the connection between the platform base and the foundation is affected by these vibrations, it may cause the foundation to settle or sink unevenly, threatening the overall balance and stability of the platform. This may lead to the platform tilting, further affecting its operational safety and production efficiency. Existing fixed bases lack effective shock absorption structures and cannot effectively mitigate the vibrations from waves and drilling equipment, resulting in insufficient stability and safety of the platform.

[0004] To address these issues, we provide a shock-resistant mounting base for drilling platforms. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0009] The present invention is further configured such that fixing blocks are fixedly connected to all four sides of the bottom of the anti-seismic seat, and a sliding rod is fixedly connected to one side of each fixing block.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model effectively reduces the vertical vibration force from the platform body on the connecting plate by using a first damper installed at the bottom of the seismic seat.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5This utility model is a shock-resistant fixing base for a drilling platform, including a platform body 1, with shock-resistant seats 2 arranged around the bottom of the platform body 1, and a connecting plate 3 arranged on the top of the shock-resistant seats 2; a shock-absorbing component is arranged in the inner cavity of the shock-absorbing seat 2, the shock-absorbing component includes a first damper 4, the first damper 4 is fixedly connected to the inner cavity of the shock-resistant seat 2, and a support block 5 is fixedly connected to the free end of the first damper 4; the top of the support block 5 is movably connected to the bottom of the connecting plate 3 through a universal joint, and connecting rods 6 are movably connected around the perimeter of the support block 5; a connecting component is arranged on the surface of the connecting plate 3, the connecting component includes a hemisphere 7, the hemisphere 7 is fixedly connected to the top of the connecting plate 3, and bolts 8 are threadedly connected around the perimeter of the inner cavity of the connecting plate 3; locking washers 9 are slidably connected to the surface of the bolts 8.

[0027] Specifically: The platform body 1 has four anti-vibration seats 2 at the bottom to provide fixed support for the platform body 1. The connecting plate 3 consists of two parts: the top is used to connect the base and the platform body 1, and the bottom is used to connect the vertical shock absorption structure to ensure quick connection and shock absorption of the platform body 1 during use. The support block 5 is used to connect the vertical shock absorption structure and the connecting plate 3. The hemisphere 7 engages with the spherical groove at the bottom of the platform body 1 to effectively reduce vibration transmission and improve seismic performance. The locking washer 9 can provide a stronger locking effect by its own deformation.

[0028] Example 2

[0029] Please see Figures 1-5 Based on Embodiment 1, the shock absorption assembly further includes a second damper 10, which is movably connected to the periphery of the inner cavity of the seismic seat 2. A damping baffle 11 is movably connected to the free end of the second damper 10. The inner cavity of the damping baffle 11 is in contact with the surface of the connecting plate 3. Fixing blocks 12 are fixedly connected to the periphery of the bottom of the seismic seat 2. A sliding rod 13 is fixedly connected to one side of the fixing block 12. A spring 14 is sleeved on the surface of the sliding rod 13. A slider 15 is fixedly connected to one end of the spring 14. The top of the slider 15 is movably connected to one end of the connecting rod 6. The inner cavity of the slider 15 is slidably connected to the surface of the sliding rod 13. Semicircular grooves 16 are opened around the bottom of the platform. The surface of the hemisphere 7 contacts the inner cavity of the semicircular groove 16. A rubber pad 17 is fixedly connected to the top of the connecting plate 3. The rubber pad 17 is used to buffer the vibration force between the connecting plate 3 and the platform. Threaded holes are opened around the bottom of the platform. One end of the bolt 8 is threadedly connected to the inner cavity of the threaded hole.

[0030] Specifically: Multiple second dampers 10 are movably connected around the inner cavity of the seismic seat 2 via universal joints to ensure that the vibration force can be reduced when the connecting block is subjected to various lateral vibrations. The free end of the second damper 10 is movably connected to the shock-absorbing baffle 11 via a universal joint. The spring 14 on the surface of the slide rod 13 is connected to the slider 15, which can disperse the force on the second damper 10. The main shock absorption effect is still achieved by the second damper 10. The slider 15 and the connecting rod 6 mainly ensure that the second damper 10 is more stable. The rubber pad 17 has good vibration absorption performance and can effectively buffer external vibrations or impacts.

[0031] The working principle of this utility model is as follows: When the anti-vibration fixing base of the drilling platform is required, firstly, the four semi-circular grooves 16 at the bottom of the platform body 1 are engaged with the hemispheres 7 at the top of the four anti-vibration seats 2. Then, the connecting plate 3 is connected to the platform body 1 by bolts 8, so that the locking washer 9 can fit tightly with one side of the bottom of the connecting plate 3, ensuring the stability of the bolt 8, and the rubber pad 17 can fit with the bottom of the platform body 1, effectively buffering external vibration or impact.

[0032] When the anti-vibration fixed base is in use, and the platform body 1 is subjected to the action of waves and the vibration of drilling equipment, the support block 5, which is movably connected to the bottom of the connecting plate 3, is subjected to vertical vibration. The vibration is transmitted to the second damper 10. The second damper 10 can absorb the vibration of the platform body 1 through its own damping performance. When the second damper 10 is subjected to force, the free end contracts, which drives the connecting rod 6 to rotate and squeezes the slider 15, causing the slider 15 to move. Through the elasticity of the spring 14, the second damper 10 can be reset to provide stability and improve the damping performance of the second damper 10. When the platform body 1 is subjected to lateral vibration, the vibration can be buffered through the second damper 10 and the shock-absorbing baffle 11, thereby improving the stability of the platform.
