Description

Technical Field

[0001] This invention relates to the technical field of marine engineering equipment, and specifically to a highly stable jacket structure with lateral stabilizing cables. Background Technology

[0002] In conventional design and application, jacket structures mainly rely on their own rigid truss frame and supporting pile foundations to bear vertical loads, while resisting various lateral forces such as wind loads, wave flow loads, ship impact loads, and construction horizontal loads during service. Their resistance to lateral displacement, overturning, and vibration stability directly determines the service safety and service life of the entire engineering structure.

[0003] To address the shortcomings of traditional rigid jacket structures in lateral resistance, the industry has gradually developed optimized solutions by adding lateral stabilizing cables. These flexible steel cables, through tension restraint, enhance the lateral and overturning resistance of the jacket structure. However, existing jacket structure technologies with stabilizing cables still suffer from several unavoidable technical defects. Firstly, the tensioning anchor points of existing stabilizing cables are mostly fixed designs, rigidly fixed to the jacket structure through welding or other methods. This prevents axial adjustment of the anchor points. If actual geological conditions, service conditions, or changes in operational requirements occur, the tensioning points cannot be flexibly adjusted, resulting in extremely poor adaptability and even failure to meet design constraints. Furthermore, the fixed-point design is also unsuitable for jacket structures of different specifications and elevations, severely lacking versatility. Secondly, the existing tension adjustment and end anchoring schemes for stabilizing cables are not reliable enough. Most existing schemes use on-site jack tensioning combined with wedge anchoring, which not only makes on-site construction operations complicated and tensioning accuracy control difficult, but also poses high safety risks for high-altitude and offshore operations. Furthermore, under long-term alternating loads, the steel cables are prone to loosening and slippage, posing serious safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a highly stable guide frame structure with lateral stabilizing cables to overcome the aforementioned defects in the prior art.

[0005] A high-stability guide frame structure with lateral stabilizing cables includes a guide frame, a groove, and a slider. A rod docking seat is provided at the bottom end of the guide frame. An inner guide tube is connected through the outer side of the guide frame. An adjustment mechanism is provided on the outer side of the inner guide tube. A steel cable is wound around the outer side of a cable reel. The adjustment mechanism is fitted onto the outer side of the inner guide tube via an outer sleeve and vertically guided by the groove. Fasteners radially penetrate the outer sleeve and are threaded into corresponding fastening holes to adjust and fix the position of the outer sleeve relative to the inner guide tube. A limiting mechanism is provided inside the receiving base. The limiting mechanism is circumferentially fixed to the outer side of the slewing support shaft via a key connection to the cable reel and is used for winding and receiving the steel cable. A lubricating rubber sleeve is provided on the side support arm for the steel cable to pass through, providing lubrication and guidance for the reciprocating motion of the steel cable.

[0006] Preferably, the sliding groove, outer sleeve, fastener, fastening hole, isolation cover, and storage base constitute an adjustment mechanism. The sliding groove is distributed in a ring on the outside of the inner guide tube. The outer sleeve is provided on the outside of the inner guide tube. Fastening holes are provided at equal intervals on the outside of the outer sleeve. One side of the fastener is connected to one set of fastening holes. The storage base is welded and fixed to the other side of the outer sleeve. The isolation cover is provided directly above the storage base.

[0007] Preferably, the outer wall of the inner guide tube is provided with annular grooves, and the inner guide tube is connected to the outer tube by a guide block installed in the groove.

[0008] Preferably, the outer tube is secured by a fastener that radially penetrates its wall and is threadedly locked to a fastening hole on the outer wall of the inner guide tube.

[0009] Preferably, the slider, cable slot, clamping end cap, lubricating sleeve, side support arm, rotary support shaft, and steel cable reel constitute a limiting mechanism. One end of the steel cable is connected to the slider, the top of the slider is provided with a cable slot, the clamping end cap is provided directly above the slider, the clamping end cap is connected to the slider by bolts, the lubricating sleeve is located inside the storage base, the rotary support shaft is located inside the storage base, the outer side of the rotary support shaft is keyed to the steel cable reel, the steel cable reel is located inside the storage base, and the side support arm is located inside the storage base.

[0010] Preferably, the slider is connected to one end of the steel cable through a cable groove at its top.

[0011] Preferably, the side support arm forms a through-type guiding engagement with the steel cable through a lubricating sleeve fixedly installed on one side.

[0012] Compared with the prior art, the present invention has the following advantages: 1. This device, through its dual-dimensional adjustable design, enables flexible control of tensioning points and constraint stiffness, allowing for adaptation without modifying the main structure of the guide frame. On one hand, relying on the sliding cooperation between the outer casing and the inner guide tube, the tensioning and anchoring height of the lateral stabilizing cable is adjusted, and rigid locking is achieved with multiple sets of equally spaced fastening holes and fasteners, perfectly adapting to the installation requirements of different design elevations and different anchoring points. On the other hand, through the rotation and unwinding of the cable reel, the extension length and pre-tension of the cable can be flexibly adjusted, adapting to the constraint requirements of different geological conditions and load conditions during the installation stage.

[0013] 2. The cable end is rigidly anchored to the slider through the cable body groove, the clamping end cap, and the slider, completely eliminating the risk of cable loosening or slippage under tension. The side support arm and lubrication sleeve provide full-stroke guidance, limiting, lubrication, and resistance reduction for the cable, avoiding problems such as wire breakage and wear caused by swinging, uneven wear, and metal-to-metal friction during cable winding and unwinding, thus significantly extending the service life of the cable. At the same time, the storage base and the top isolation cover form a closed protective space, which can effectively isolate external seawater, silt, and impurities from erosion and jamming of the internal rotating parts and winding structure.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 5As shown, a high-stability guide frame structure with lateral stabilizing cable includes a guide frame 1, a groove 4, and a slider 11. A rod docking seat 2 is provided at the bottom end of the guide frame 1. An inner guide tube 3 is connected through the outer side of the guide frame 1. An adjustment mechanism is provided on the outer side of the inner guide tube 3. A steel cable 10 is wound around the outer side of a steel cable reel 17. The adjustment mechanism is fitted onto the outer side of the inner guide tube 3 via an outer sleeve 5 and is vertically guided and adjusted via the groove 4. Fasteners 6 radially penetrate the outer sleeve 5 and are threadedly locked to corresponding fastening holes 7 to adjust and fix the position of the outer sleeve 5 relative to the inner guide tube 3. A limiting mechanism is provided inside the receiving base 9. The limiting mechanism is circumferentially fixed to the outer side of the rotary support shaft 16 via a key connection through the steel cable reel 17, and is used to wind and receive the steel cable 10. A lubricating sleeve 14 is installed on the side support arm 15, allowing the steel cable 10 to pass through and providing lubrication and guidance for the reciprocating motion of the steel cable 10.

[0018] In this embodiment, the sliding groove 4, outer sleeve 5, fastener 6, fastening hole 7, isolation cover 8, and storage base 9 constitute an adjustment mechanism. The sliding groove 4 is distributed in a ring on the outside of the inner guide tube 3. The outer sleeve 5 is provided on the outside of the inner guide tube 3. Fastening holes 7 are provided at equal intervals on the outside of the outer sleeve 5. One side of the fastener 6 is connected to one set of fastening holes 7. The storage base 9 is welded and fixed to the other side of the outer sleeve 5. The isolation cover 8 is provided directly above the storage base 9. The outer wall of the inner guide tube 3 is evenly distributed with sliding grooves 4 in a ring. The inner guide tube 3 is slidably connected to the outer sleeve 5 through the guide block installed in the sliding groove 4. The outer sleeve 5 is threadedly locked and fixed to the fastening hole 7 opened on the outer wall of the inner guide tube 3 by the fastener 6 that is radially penetrating its tube wall.

[0019] Wherein: the steel cable 10 passes through the inner hole of the lubricating sleeve 14 along the axial direction, forming a through-type guiding fit with the lubricating sleeve 14. On the one hand, the inner hole of the lubricating sleeve 14 forms a radial limit on the steel cable 10, avoiding large swings and uneven wear during the winding and unwinding of the steel cable 10 and the stress process, and ensuring the stability of the force path of the steel cable. On the other hand, the self-lubricating properties of the lubricating sleeve 14 greatly reduce the frictional resistance of the steel cable 10 during reciprocating motion, avoid wear and wire breakage caused by direct contact between the steel cable and metal parts, and extend the service life of the steel cable.

[0020] In this embodiment, the slider 11, cable groove 12, clamping end cap 13, lubricating sleeve 14, side support arm 15, rotary support shaft 16, and steel cable reel 17 constitute a limiting mechanism. One end of the steel cable 10 is connected to the slider 11. The top of the slider 11 is provided with the cable groove 12. The clamping end cap 13 is provided directly above the slider 11. The clamping end cap 13 is connected to the slider 11 by bolts. The lubricating sleeve 14 is disposed inside the receiving base 9. The storage base 9 is equipped with a rotary support shaft 16 inside. A steel cable reel 17 is keyed to the outside of the rotary support shaft 16. The steel cable reel 17 is located inside the storage base 9. A side support arm 15 is also located inside the storage base 9. The slider 11 is connected to one end of the steel cable 10 through a cable slot 12 at its top. The side support arm 15 is connected to the steel cable 10 through a lubricating sleeve 14 fixedly installed on one side.

[0021] Specifically: When the guide frame 1 is subjected to lateral forces such as wind load, wave load, and horizontal construction load during service, and tends to undergo lateral displacement and overturning deformation, the pre-tensioned steel cable 10 directly constrains the lateral deformation of the guide frame through axial tension, and transfers the lateral load to the anchor foundation through the steel cable, thus offsetting the lateral displacement moment of the guide frame; during this process, the rigid locking structure of the adjustment mechanism ensures that the tension anchor point does not shift or loosen, ensuring the effective transfer of the tension load, and the anchoring structure of the limiting mechanism ensures that the end of the steel cable does not loosen.

[0022] In practical applications, this highly stable guide frame structure with lateral stabilizing cables includes the following tasks: The inner guide tube 3 is fixedly inserted through the outer side of the guide tube frame 1, serving as the reference bearing for the entire adjustment action. Its outer wall has grooves 4 distributed in a ring shape, providing vertical guidance constraints for the adjustment action. The outer tube 5 is sleeved on the outer side of the inner guide tube 3. Through the guide block installed in the groove 4, it forms an axial sliding fit with the inner guide tube 3, and can move vertically up and down along the axial direction of the inner guide tube 3, simultaneously driving the storage base 9 welded and fixed on the outer tube 5, as well as the entire set of limiting mechanisms inside the storage base 9 to move synchronously. After the outer tube 5 is adjusted to the preset target position, the fastener 6, which is radially inserted through the wall of the outer tube 5, is aligned with the fastening holes 7, which are equally spaced and located at the corresponding positions on the outer wall of the inner guide tube 3. The fastener 6 is tightened by screwing to lock and fix the tube. The threaded engagement between the fastener 6 and the fastening hole 7 can completely eliminate the gap between the outer tube 5 and the inner guide tube 3, and rigidly lock the two together. The main body of the steel cable 10 is wound around the outside of the steel cable reel 17, and one end of it is connected to the slider 11. The end of the steel cable 10 is anchored without slippage through the slider 11, the cable body groove 12 and the pressing end cap 13. The top of the slider 11 has a cable body groove 12. The end of the steel cable 10 is inserted into the cable body groove 12 to form a limiting engagement connection. The pressing end cap 13 is placed on top of the cable body groove 12. The pressing end cap 13 is locked and fixed to the slider 11 by bolts, thereby completely pressing and limiting the end of the steel cable 10 within the groove cavity of the cable body groove 12. The main body of the steel cable 10 is wound and stored on the outside of the steel cable reel 17. The slewing support shaft 16 is installed inside the storage base 9. The steel cable reel 17 is circumferentially locked and fixed on the outside of the slewing support shaft 16 by a key connection. The slewing support shaft 16 provides stable slewing support for the steel cable reel 17. By driving the steel cable reel 17 to rotate forward and backward around the slewing support shaft 16, the winding and unwinding of the steel cable 10 can be realized, thereby adjusting the extension length of the steel cable 10 and applying a preset tension force to the steel cable 10. The storage base 9 is also equipped with a side support arm 15. The lubricating sleeve 14 is fixedly installed on one side of the side support arm 15. The steel cable 10 passes through the inner hole of the lubricating sleeve 14 along the axis and forms a through-type guide fit with the lubricating sleeve 14. Through the self-lubricating properties of the lubricating sleeve 14, the frictional resistance of the steel cable 10 during reciprocating motion is greatly reduced.

[0023] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
