Description

Technical Field

[0001] This invention relates to the field of suspended conveyor systems, and in particular to an adaptive loading and unloading buffer device for offshore platforms in response to wind and waves. Background Technology

[0002] Offshore engineering platforms, also known as marine engineering platforms, are important facilities used for offshore engineering operations. They are structures built at sea for various marine-related engineering projects, providing a stable working environment for offshore operations. Cargo transportation on offshore engineering platforms is a key link in the marine engineering industry chain, and commonly used cargo loading and unloading equipment includes cranes, overhead conveyor systems, and belt conveyors.

[0003] For example, Chinese patent application CN216833794U discloses a transportation device for offshore platform construction. During operation, the device increases the storage area of ​​the transportation device to facilitate the transport of more goods, thereby enabling flexible loading and unloading of goods. This not only reduces the difficulty of loading and unloading goods to a certain extent, but also effectively improves the efficiency of loading and unloading goods. When existing offshore engineering platforms use suspended conveyor equipment to load and unload bulk cargo, the platforms are affected by sea waves, causing the cargo to sway and sag. Under the influence of wind and waves, the center of gravity of the cargo shifts, increasing the risk of the cargo overturning. At the same time, the sag of the cargo increases the risk of the suspension ropes breaking due to excessive tension. This will adversely affect the safety and stability of cargo transportation on the offshore engineering platform. Summary of the Invention

The energy-absorbing component includes a cavity embedded inside the fixing frame, the cavity extending to the lower side of the fixing frame, a movable seat slidably connected inside the cavity, and a buffer sleeve fixedly connected to the upper outer surface of the movable seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a buffer component, when the impact force of wind and waves is transmitted to the traction rod through the guide seat, the ball will come into contact with one of the induction plates under the action of inertia. The electromagnet will be subjected to the magnetic repulsion force of the magnetic ring, which helps to buffer and absorb the impact force of wind and waves on the support seat. This can reduce the movement range between the support frame and the traction rod to a certain extent, which helps to improve the stability of the track conveying track and thus effectively improve the accuracy of cargo conveying. 2. This solution incorporates energy-absorbing components. When goods sway due to inertia, the movable seat, in conjunction with the fixed frame, compresses the buffer sleeve. During its movement, the sliding sleeve drives the contact plate to move synchronously, causing the outer surface of the contact plate to contact the inner wall of the cavity. The friction between the contact plate and the inner wall of the cavity, combined with the elasticity of the spring, buffers and absorbs the impact force on the fixed frame, thereby reducing the impact force on the tie rod to a certain extent. This further improves the stability of the track and the transport of goods, reducing the risk of goods accidentally falling due to wind and waves. 3. This solution uses a compensation component. The buffer rod extends outward from the inside of the slot under the push of the pull rod. The extended buffer rod contacts the support frame, which further increases the sliding friction between the support frame and the support sleeve. The friction can effectively absorb the impact of wind and waves, thereby effectively improving the buffering effect on the support frame 13 and helping to maintain the stability of the overall track structure.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 10 The present invention provides a technical solution: An adaptive loading and unloading buffer device for offshore platforms includes a support base 11, a support frame 13, and a guide rail 16. A surrounding plate 12 is fixedly connected to the upper outer surface of the support base 11. The upper outer surface of the support base 11 slides in contact with the lower end of the support frame 13. A buffer assembly is provided on the outer side of the support frame 13. The buffer assembly includes a traction rod 28 slidably connected to the support frame 13. A magnetic ring 27 is fixedly connected to the outer surface of the traction rod 28. Electromagnets 47 are symmetrically fixedly connected to the left and right sides of the outer surface of the support frame 13. A movable cavity 48 is embedded in the inner side of the traction rod 28. A ball bearing 50 is movably connected to the inner surface of the movable cavity 48. A sensing plate 49 is fixedly connected to the inner surface of the movable cavity 48. The inner surface of the movable cavity 48 is symmetrically conical.

[0021] The inner surface of the enclosure 12 is fixedly connected to a guide seat 14, and the outer surface of the traction rod 28 is in sliding contact with the guide seat 14. The number of magnetic rings 27, induction plates 49 and electromagnets 47 are all in two sets and are symmetrically distributed. The electromagnets 47 are in the shape of a ring and are sleeved on the outside of the traction rod 28. The electromagnets 47 and induction plates 49 are electrically connected to the buffer device control system respectively. The enclosure 12 has a U-shaped structure.

[0022] By adopting the above technical solution, offshore platforms often use suspended conveyor devices to achieve continuous cargo transportation. Several sets of fixed seats are sequentially fixed to the surface of the offshore platform according to the arrangement direction of the guide rails 16. Support seats 11 are used to support the guide rails 16 via support frames 13. Offshore platforms are subject to fluctuations due to wind and waves. To reduce the impact of wind and waves on the stability of cargo transportation and unloading, buffer components are installed. Support seats 11 are used to fix and support the bulkhead 12. Guide seats 14 on the surface of the bulkhead 12 are used to slide and support the towing rod 28. The towing rod 28 passes through both ends of the support frame 13, guiding the support frame 13. When the support seats 11 on the offshore platform are impacted by wind and waves in the left and right directions, the cargo will sway under inertia. The impact force of the wind and waves will be transmitted to the towing rod 28 through the guide seats 14. At this time, the support frame 13, under inertia, will... Relative sliding will occur between the traction rods 28. At this time, the ball bearing 50 will come into contact with one of the induction plates 49 under the action of inertia. The induction plate 49 sends an electrical signal to control the magnetic direction of the electromagnet 47, so that the electromagnet 47 on the side in contact with the ball bearing 50 and the magnetic ring 27 on the outside of the traction rod 28 are magnetically opposite. At this time, the electromagnet 47 will be subjected to the magnetic repulsion force of the magnetic ring 27, which helps to buffer and absorb the impact force of wind and waves on the support base 11. This can reduce the movement amplitude between the support frame 13 and the traction rod 28 to a certain extent, which helps to improve the erection stability of the rail conveyor and thus effectively improve the accuracy of cargo transportation. When the wind and waves on the offshore platform gradually decrease, since the inner surface of the movable cavity 48 is symmetrically conical, the ball bearing 50 will stay in the middle of the movable cavity 48 under the action of gravity, thus keeping the position of the ball bearing 50 stable.

[0023] Specifically, such as Figure 2 , Figure 5 and Figure 8 As shown, a conveying assembly is provided on the outer side of the guide rail 16. The conveying assembly includes rollers 22 that are rotatably connected to the inner surface of the guide rail 16. A mounting shaft 29 is rotatably connected to the inner surface of the rollers 22. A conveying frame 21 is rotatably connected to the outer surface of the mounting shaft 29. The guide rail 16 has an I-shaped cross-section. A connecting rod 30 for suspending goods is fixedly connected to the lower end of the conveying frame 21. There are two sets of rollers 22 that are symmetrically distributed.

[0024] The support frame 13 is provided with a fixing component for traction support of the guide rail 16 on its outer side. The fixing component includes a reinforcing plate 17 fixedly connected to the outer surface of the front end of the support frame 13. The support frame 13 has an L-shaped structure. The lower end of the support frame 13 is fixedly connected to a fixing frame 18.

[0025] A tie rod 19 is fixedly connected to the lower end of the fixed frame 18, and a connecting plate 20 is fixedly connected to the lower end of the tie rod 19. The lower outer surface of the connecting plate 20 is fixedly connected to the upper end of the guide rail 16. The number of the fixed components is several groups, which are equidistantly distributed along the outer side of the guide rail 16. The several groups of support seats 11 are respectively connected to the ground and the outer surface of the offshore platform by anchor bolts.

[0026] By adopting the above technical solution, when the offshore platform transports cargo, the support base 11 is first fixed to the surface of the offshore platform with anchor bolts, so that the support base 11 and the offshore platform form a stable connection. The support base 11 is used to slide support the support frame 13. The reinforcing plate 17 can effectively improve the structural strength and support performance of the support frame 13. The support frame 13 elastically supports the tie rod 19 through the fixing frame 18. The tie rod 19 is fixedly connected to the guide rail 16 through the connecting plate 20. By setting up several sets of support frames 13 to suspend and support the guide rail 16, the position of the guide rail 16 is kept relatively stable. The guide rail 16, as the core component of the suspended conveying system, is used to support and guide the roller 22. The guide rail 16 has an I-shaped structure. The structure includes rollers 22 located inside the guide rail 16, which can move along the mounting direction of the guide rail 16. The rollers 22 are rotatably supported by the mounting shaft 29 and the conveyor frame 21. The power module of the suspended conveyor system drives the rollers 22 to move inside the guide rail 16. In the prior art, the power module of the suspended conveyor system often uses chain drive or other methods to provide power, so its specific structure and working principle will not be described in detail here. The connecting rod 30 on the lower side of the conveyor frame 21 is used to suspend the goods. The movement of the conveyor frame 21 and the rollers 22 can drive the goods to move along the mounting direction of the guide rail 16. By setting up several sets of conveyor frames 21, continuous transportation of goods can be achieved, thereby improving the efficiency of goods transportation to a certain extent.

[0027] Specifically, such as Figure 5 and Figure 8 As shown, an energy-absorbing component is provided inside the fixed frame 18. The energy-absorbing component includes a cavity 31 embedded inside the fixed frame 18. The cavity 31 extends to the lower side of the fixed frame 18. A movable seat 33 is slidably connected inside the cavity 31. A buffer sleeve 32 is fixedly connected to the upper outer surface of the movable seat 33. The upper outer surface of the buffer sleeve 32 is fixedly connected to the upper surface of the inner surface of the cavity 31.

[0028] A spring 26 is fixedly connected to the lower side of the inner surface of the buffer sleeve 32. An injection hole 25 is embedded in the outer surface of the upper end of the fixing bracket 18. The injection hole 25 is connected to the inside of the buffer sleeve 32. The buffer sleeve 32 is filled with hydraulic oil. The outer surface of the lower end of the movable seat 33 is fixedly connected to the upper end of the pull rod 19. The buffer sleeve 32 is made of wear-resistant elastic material.

[0029] The outer surface of the pull rod 19 has a through cavity 35. A sliding sleeve 37 is slidably connected to the inner side of the through cavity 35. A contact plate 36 is fixedly connected to the outer surface of the sliding sleeve 37. The contact plate 36 is made of wear-resistant material. There are two sets of sliding sleeves 37 and contact plates 36, which are symmetrically distributed. A spring 38 is fixedly connected between the two sets of sliding sleeves 37. A through hole 34 is embedded in the inner side of the pull rod 19. One end of the through hole 34 is connected to the inside of the buffer sleeve 32, and the other end extends into the inside of the through cavity 35.

[0030] By adopting the above technical solution, under normal working conditions, the movable seat 33 will be located at the lowest side inside the cavity 31 under the elastic force of the spring 26. The lower side of the cavity 31 can limit the movable seat 33. The fixed frame 18 can be fixedly supported by the movable seat 33. When the support frame 13 and the support seat 11 are subjected to the impact force of vertical wind and waves, the goods will sway under the action of inertia. The movable seat 33 and the fixed frame 18 will slide relative to each other. When the movable seat 33 moves towards the buffer sleeve 32 inside the cavity 31, the movable seat 33 and the fixed frame 18 will squeeze the buffer sleeve 32. At this time, the hydraulic oil inside the buffer sleeve 32 will flow through the through hole 34 to the continuous Inside the cavity 35, the hydraulic oil pressure inside the cavity 35 continuously increases. Under the action of hydraulic pressure, the sliding sleeve 37 slides along the inner wall of the cavity 35 to both sides. During the movement, the sliding sleeve 37 drives the contact plate 36 to move synchronously and stretches the second spring 38, so that the outer surface of the contact plate 36 contacts the inner wall of the cavity 31. Through the friction between the contact plate 36 and the inner wall of the cavity 31, combined with the elastic force of the first spring 26, the impact force on the fixed frame 18 can be buffered and absorbed, thereby reducing the impact force on the pull rod 19 to a certain extent, and further improving the stability of the track and cargo transportation, so as to reduce the risk of cargo falling accidentally due to wind and waves.

[0031] Specifically, such as Figure 6 and Figure 9 As shown, a compensation component is provided on the inner side of the enclosure 12. The compensation component includes a guide groove 15 embedded in the inner surface of the enclosure 12. A slide rod 23 is slidably connected to the inner side of the guide groove 15. A limit plate 45 is slidably connected to the outer surface of the slide rod 23. A support sleeve 24 is fixedly connected to the outer surface of the limit plate 45. The support sleeve 24 passes through both ends of the support frame 13 and is fixedly connected to the support frame 13.

[0032] The outer surface of the slide rod 23 is embedded with a limiting groove 44. The outer surface of the slide rod 23 is linearly slidably connected to an ear plate 39 through the limiting groove 44. The outer surface of the ear plate 39 is fixedly connected to a first pin 40. The outer surface of the first pin 40 is rotatably connected to a movable rod 41. The side of the movable rod 41 away from the first pin 40 is fixedly connected to a second pin 42. The outer surface of the second pin 42 is rotatably connected to a buffer rod 43. The number of buffer rods 43 is several groups and they are distributed in a ring array. The outer surface of the support sleeve 24 is embedded with a slot 46. The position of the slot 46 corresponds to the buffer rod 43.

[0033] By adopting the above technical solution, in order to further improve the support stability of the support base 11 on the support frame 13, a compensation component is set up. The surrounding plate 12 slides to support the slide rod 23 through the guide groove 15, so that the slide rod 23 can slide linearly inside the guide groove 15. The slide rod 23 slides to support the support sleeve 24 through the limiting plate 45. When the support base 11 is affected by wind and waves, causing relative movement between the support sleeve 24 and the slide rod 23, relative sliding will occur between the limiting plate 45 and the slide rod 23. The limiting groove 44 on the surface of the slide rod 23 not only allows the ear plate 39 to slide linearly along the surface of the slide rod 23, but also limits the ear plate 39, so that the ear plates 39 slide at the position corresponding to the limiting groove 44. When one side of the limiting plate 45 contacts the outer surface of the ear plate 39, it will limit one set of ear plates 39. The first set of ear plates 39 is pushed forward, while the other set of ear plates 39 remains stationary under the limiting action of the limiting groove 44. At this time, the distance between the two sets of ear plates 39 will gradually decrease. The ear plates 39 support the movable rod 41 through the first pin 40, and the movable rod 41 supports the buffer rod 43 through the second pin 42. As the distance between the two sets of ear plates 39 gradually decreases, the angle between the movable rod 41 and the slide rod 23 will gradually increase. At this time, the buffer rod 43 is pushed outward from the inside of the groove 46 under the push of the movable rod 41. The contact between the extended buffer rod 43 and the support frame 13 can further increase the sliding friction between the support frame 13 and the support sleeve 24. The friction can effectively absorb the impact of wind and waves, thereby effectively improving the buffering effect on the support frame 13 and helping to maintain the stability of the overall track structure.

[0034] Working principle: When the offshore platform loading and unloading buffer device is in operation, the support base 11 is first fixed to the surface of the offshore platform with anchor bolts, so that the support base 11 and the offshore platform form a stable connection. The support base 11 is used to slide support the support frame 13. Several sets of support frames 13 are set to suspend and support the guide rail 16. The rollers 22 are set inside the guide rail 16 and can move along the erection direction of the guide rail 16. The connecting rod 30 on the lower side of the conveyor frame 21 is used to suspend the cargo. The movement of the conveyor frame 21 and the rollers 22 can drive the cargo along the erection direction of the guide rail 16. The platform can move continuously by setting up several sets of conveyor frames 21. When the support base 11 on the offshore platform is impacted by wind and waves from the left and right, the support frame 13 will slide relative to the traction rod 28 under the action of inertia. At this time, the ball bearing 50 will come into contact with one of the sets of induction plates 49 under the action of inertia. The induction plate 49 sends an electrical signal to control the magnetic direction of the electromagnet 47, so that the electromagnet 47 on the side in contact with the ball bearing 50 is magnetically opposite to the magnetic ring 27 on the outside of the traction rod 28. At this time, the electromagnet 47 will be repelled by the magnetic ring 27. The force helps to buffer and absorb the impact of wind and waves on the support base 11. When the movable seat 33 moves towards the buffer sleeve 32 inside the cavity 31, the movable seat 33, together with the fixed frame 18, will squeeze the buffer sleeve 32. The hydraulic oil inside the buffer sleeve 32 will flow into the connecting cavity 35 through the through hole 34. The sliding sleeve 37 will slide to both sides along the inner wall of the connecting cavity 35 under the action of hydraulic pressure. During the movement, the sliding sleeve 37 will drive the contact plate 36 to move synchronously. Through the friction between the contact plate 36 and the inner wall of the cavity 31, the fixed frame 18 can be compressed. The impact force received by the 8 is buffered and absorbed. When one side limit plate 45 contacts the outer surface of the ear plate 39, it will push one of the ear plates 39. The movable rod 41 supports the buffer rod 43 through the pin 42. The buffer rod 43 gradually extends outward from the inside of the slot 46 under the push of the movable rod 41. The extended buffer rod 43 contacts the support frame 13, which can further increase the sliding friction between the support frame 13 and the support sleeve 24. The friction can effectively absorb the impact force of wind and waves, thereby effectively improving the buffering effect on the support frame 13.
