Description

Technical Field

[0001] This invention relates to the field of hose recycling technology, specifically a floating hose recycling system and device. Background Technology

[0002] The floating hose system of an FPSO (Floating Production Storage and Offloading) unit is a core component of its external transport system, responsible for the safe and efficient transfer of crude oil stored in the FPSO to shuttle tankers. This system comprises a complete crude oil transport system consisting of a hose winch, hoses and their connectors, a hose laying device, an emergency release system, a power and control system, and auxiliary equipment. Currently, there are two main technical approaches to hose laying devices in the industry: fixed and split-type. Fixed hose laying devices are rigidly connected to the winch body via supports and often use mechanical transmission methods such as sprockets and chains to achieve synchronous operation with the storage drum. Split-type devices, on the other hand, have the hose laying mechanism independently located on the ship's side, separate from the winch body located in other areas of the deck, relying on sensors and control systems to synchronize their movements. While these two structures each have their own characteristics, they still face a series of technical challenges in actual marine operating environments.

[0003] In realizing this invention, current hose winches are mostly single-tube structures with limited storage pipe length. Double-layer winding easily aggravates surface wear, reduces hose life, and increases maintenance costs. Furthermore, their lack of modularity makes them difficult to adapt to the efficient loading and unloading of different hoses. In addition, a single winch can typically only dock with one shuttle tanker, limiting the number that can be deployed when deck space is limited, thus affecting crude oil export efficiency. During hose deployment and retrieval, the motor operation, ship sway, and wind and waves can easily cause excessive tension. Existing pipe-laying devices often lack effective protection mechanisms or have slow responses, resulting in insufficient flexibility and precision in hose position control. Simultaneously, the system lacks driving force assistance, relying entirely on the main winch for hose deployment and retrieval. During long-distance operations, high frictional resistance can easily lead to motor overload, tension loss, or slippage. In emergency release, traditional guides still constitute mechanical constraints, hindering the rapid radial ejection of the hose, affecting the release speed and trajectory, and potentially scratching the hose.

[0004] Based on this, a floating hose retrieval system and apparatus are provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention features a double-layer cylinder structure design. After the inner cylinder finishes winding the hose, the flip plate is closed to allow for the outer layer winding. Furthermore, a guiding mechanism ensures that the hose is evenly wound on both the inner and outer cylinders. This structure significantly reduces the contact area between the hoses, effectively alleviating surface wear, extending the hose's service life, and reducing maintenance costs. At the same time, the double-layer winding method significantly reduces the overall volume of the recovery device, making its arrangement on the deck more flexible and improving deck space utilization.

[0018] 2. This invention enables dual-transmission operation with a single machine by adding a detachable oil delivery interface. The power and control unit first controls the first motor to drive the outer cylinder to rotate, lowering all the outer hoses; then, the outer tilting plate is opened, followed by the release of the inner cylinder hoses, allowing crude oil to be simultaneously delivered to two shuttle tankers via the same winch. This design improves operational efficiency and the equipment's multi-tasking adaptability.

[0019] 3. This invention features a guiding mechanism that makes it lightweight and easy to assemble and disassemble. The traction rope and the winding reel have flexible contact, resulting in significantly less wear than gear meshing. Furthermore, it can absorb impact through elastic deformation in the event of an accidental collision, providing passive compliance and protecting critical drive components. The rotating rod and guide can swing down synchronously, quickly creating clearance for the hose and improving response speed.

[0020] 4. By using the liftable first and second guide wheels, the auxiliary drive and rapid constraint release functions are integrated into one, simplifying the system structure. In normal mode, it can provide auxiliary drive, reduce the load on the first motor, and improve the accuracy of synchronous control and tension management. In emergency mode, it can quickly release the constraint on the hose, achieve high-speed and unobstructed throwing, and greatly enhance the safety of operation. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, such as Figures 1-9 As shown, a floating hose recovery device includes an inner drum 11 and a mounting shaft 12. Several first support rods 13 are arrayed at both ends of the inner drum 11. The other ends of each first support rod 13 are fixedly connected to the mounting shaft 12. An extension shaft 14 is fixedly mounted at one end of the mounting shaft 12. Support seats are rotatably mounted at one end of both the extension shaft 14 and the mounting shaft 12. Two support seats are respectively fixed to the upper ends of a first support frame 15 and a second support frame 16. An outer drum 22 is fitted to the outside of the inner drum 11. Connecting components connecting to the inner drum 11 are provided at both ends of the outer drum 22. A clutch mechanism for switching the working state of the outer drum 22 is provided at the upper end of the first support frame 15. A guide mechanism for guiding the hose is provided between the first support frame 15 and the second support frame 16. The clutch mechanism facilitates switching the working state of the outer drum 22, allowing for double-layer winding and unwinding of the hose. The guide mechanism guides and assists in conveying the hose, while also absorbing impact.

[0033] One end of the extension shaft 14 is fixedly connected to the output end of the reducer 17. The reducer 17 is installed on the upper end of the first support frame 15. The input end of the reducer 17 is fixedly connected to the output end of the first motor 18. The first motor 18 is installed at the bottom end of the first support frame 15 and is electrically connected to the control component. The control component is installed on one side of the first support frame 15. The end of the mounting shaft 12 is provided with a mounting hole. The inner drum 11 is provided with a mounting hole. When it is necessary to wind up the hose, the control component controls the first motor 18 to start. The output end of the first motor 18 drives the reducer 17 to rotate. The reducer 17 drives the mounting shaft 12 to rotate through the extension shaft 14. The mounting shaft 12 drives the inner drum 11 to rotate, and one end of the hose passes through the mounting hole and the inside of the mounting shaft 12. Then the inner drum 11 can wind up the hose.

[0034] The connecting assembly includes a first fixing ring 19, a bearing 20, and a second fixing ring 21. The inner drum 11 has first fixing rings 19 fitted at both ends. Each first fixing ring 19 is fixedly connected to the inner drum 11 via several second support rods. Bearings 20 are installed on the outer side of each first fixing ring 19, and second fixing rings 21 are installed on the outer rings of each bearing 20. Limit rings are installed on one side of each of the first fixing rings 19 and the second fixing ring 21. Two second fixing rings 21 are respectively installed at both ends of the outer drum 22. The outer drum 22 has an installation notch, within which a flip plate 23 is hinged. A transition plate 24 is provided within the installation notch, and the transition plate 24 is inclined. Guide grooves are provided at both ends of the flip plate 23, allowing sliding within the guide grooves. A sliding column is provided, which is fixedly mounted on one end of the drive rod 25. The other end of the drive rod 25 is provided with a transmission shaft. One of the transmission shafts is fixedly connected to the drive hole of the first hollow shaft servo motor 26. The first hollow shaft servo motor 26 is mounted on one side of the second fixing ring 21. The other transmission shaft is connected to the input end of the first rotary encoder. A detachable oil inlet 55 is installed on one of the second fixing rings 21. In use, when the inner drum 11 is winding the hose, the control unit controls the first hollow shaft servo motor 26 to start. The first hollow shaft servo motor 26 drives the drive rod 25 to rotate. The drive rod 25 drives the flip plate 23 to unfold through the sliding column. At the same time, the first rotary encoder can monitor the deflection angle of the flip plate 23, so that the hose is wound on the inner drum 11.

[0035] The clutch mechanism includes a stop gear 39 and plug rods 40. A stop gear 39 is installed on one side of a second fixing ring 21. A plurality of plug rods 40 are fitted inside the stop gear 39. A fixing tube 41 is slidably provided on the outer side of each plug rod 40. The fixing tube 41 is installed on one side of the first support rod 13. A first mounting groove is provided in the middle of the plug rod 40. A first limiting plate is slidably provided in the first mounting groove. The first limiting plate is fixedly provided inside the fixing tube 41. One end of the first mounting groove... A first return spring 42 is provided between the first limiting plate and one side. Each end of the insertion rod 40 is hinged to a connecting rod 43, and the other end of each connecting rod 43 is hinged to a hinge seat. The hinge seats are all fixedly mounted on a rotating ring 44. The rotating ring 44 is rotatably disposed within the outer annular groove of a sliding ring 45. The sliding ring 45 is slidably disposed outside a drive tube 46. The drive tube 46 is sleeved on an extension shaft 14. A plurality of limiting blocks are arrayed on the inner side of the sliding ring 45, and the outer side of the drive tube 46 corresponds to the position of the limiting blocks. Each part is provided with a limiting groove. One end of the drive tube 46 is fixedly provided with a first fixing plate, which is fixedly connected to the output end of the electric cylinder 47. The electric cylinder 47 is installed on the upper end of the first support frame 15. In use, when the inner winding drum 11 has finished winding the hose and the outer drum 22 needs to wind the hose, the flip plate 23 is closed. Then, the control component controls the electric cylinder 47 to start. The output end of the electric cylinder 47 drives the drive tube 46 to slide. When the limiting block is in close contact with one end of the limiting groove, the drive tube 46 slides. Ring 45 drives several hinge seats to move. The hinge seats drive the plug rod 40 to slide inside the fixed tube 41 through the connecting rod 43. After one end of the plug rod 40 is inserted between the teeth of the inner side of the stop gear 39, the output end of the electric cylinder 47 stops extending, so that the inner roll 11 is fixedly connected to the outer roll 22. Then, while the first motor 18 drives the inner roll 11 to rotate, the outer roll 22 rotates accordingly, so that the outer roll 22 winds up the hose. The inner side of the first support frame 15 is provided with a fixing component for fixing the outer roll 22.

[0036] The fixing assembly includes a fixing base 54, which is fixedly disposed on one side of the second fixing ring 21. A rod 53 is inserted into one end of the fixing base 54 and fixedly disposed on one end of a sliding rod 51. The sliding rod 51 is slidably disposed inside the mounting tube. A second mounting groove is provided in the middle of the sliding rod 51, and a second limiting plate is slidably disposed within the second mounting groove. The second limiting plate is fixedly disposed inside the mounting tube. A tension spring 52 is provided between one side of the second limiting plate and one end of the second mounting groove. A guide groove rod 50 is fixedly disposed on one end of the sliding rod 51, and a mounting slide groove is provided on one side of the guide groove rod 50. A fixing post is slidably disposed within the mounting slide groove. The fixed column is fixedly installed at one end of the rotating plate 49, which is rotatably installed inside the first support frame 15. The other end of the rotating plate 49 is closely attached to the drive plate 48, which is fixedly installed at one end of the first fixed plate. In use, when the inner drum 11 is winding, the output end of the electric cylinder 47 drives the drive plate 48 to move to the initial position. At this time, the drive plate 48 pushes the rotating plate 49 to rotate. The rotating plate 49, through the fixed column and the guide groove rod 50, pushes the sliding rod 51 to slide inside the installation tube, so that the sliding rod 51 drives the insertion rod 53 to slide. One end of the insertion rod 53 is inserted into the end of the fixed seat 54, thereby fixing the outer drum 22.

[0037] The guiding mechanism includes a first guide wheel 27 and a second guide wheel 28, both of which are rotatably mounted inside the mounting frame. A piezoresistive pressure sensor 33 is mounted on one end of the mounting frame, which is slidably mounted on the guide frame. A guide 32 is fixedly mounted on the bottom end of the mounting frame, and the guide 32 is mounted on a lead screw 30, which is rotatably mounted inside the guide frame. One end of the lead screw 30 is fixedly connected to the output end of a third motor 31, which is mounted on one end of the guide frame. One end of the first guide wheel 27 is fixedly connected to the output end of a second motor 29, which is mounted on one side of the mounting frame. Rotating rods 34 are mounted on both ends of the guide frame, and hinged rods 35 are hinged to the other ends of the rotating rods 34. Connecting seats are hinged to the other ends of the hinged rods 35, and the two connecting seats are respectively fixed on one side of the first support frame 15 and the second support frame 16.

[0038] Several traction ropes 36 are connected to the end of the rotating rod 34. The other end of each traction rope 36 is connected to a take-up reel 37. The take-up reel 37 has a guide spiral groove on its inner side. One end of the take-up reel 37's rotating shaft is fixedly connected to the drive hole of a second hollow shaft servo motor 38, which is mounted on a connecting seat. One end of the take-up reel 37's rotating shaft is fixedly connected to the drive hole of a third hollow shaft servo motor. The other end of the take-up reel 37's rotating shaft is connected to the input end of a second rotary encoder. In use, when winding or unwinding the hose, the second motor 29 is started, driving the first guide wheel 27 to rotate. The first guide wheel 27... The hose provides auxiliary delivery, while the third motor 31 is activated. The third motor 31 drives the lead screw 30 to rotate. The lead screw 30, in conjunction with the guide 32, moves the first guide wheel 27 and the second guide wheel 28, thereby guiding and winding the hose. Simultaneously, the piezoresistive pressure sensor 33 monitors the hose pressure in real time. If the pressure exceeds a threshold, the piezoresistive pressure sensor 33 sends a signal to the control unit. The control unit immediately calculates the avoidance trajectory and, through inverse kinematics calculation, coordinates the second hollow shaft servo motor 38 driving the end joint, causing the rotating rod 34 and the hinge rod 35 to actively swing down at a certain angle, providing avoidance space for the hose. After the pressure returns to normal, the system automatically resets or prompts for manual intervention. This mechanism utilizes the elastic deformation of the traction rope 36 to absorb impact and avoid rigid damage.

[0039] The above embodiment discloses a floating hose recovery device, wherein, during inner winding, the electric cylinder 47 is in a retracted state, the insertion rod 53 is in an inserted state with the fixing seat 54, thereby fixing the outer cylinder 22. The first hollow shaft servo motor 26 drives the flip plate 23 to open. Subsequently, the control unit controls the first motor 18, the second motor 29 and the third motor 31 to start. The second motor 29 drives the first guide wheel 27 to rotate, and the first guide wheel 27 assists in conveying the hose. At the same time, the third motor 31 is started, and the third motor 31 drives the lead screw 30 to rotate. The lead screw 30 cooperates with the guide 32 to drive the first guide wheel 27 and the second guide wheel 28 to move, thereby guiding and winding the hose, and the inner winding cylinder 11 winds it up. After completion, the first hollow shaft servo motor 26 drives the flip plate 23 to close. Then, the control unit controls the electric cylinder 47 to start. The output end of the electric cylinder 47 drives the drive tube 46 to slide. When the limit block is in close contact with one end of the limit groove, the drive tube 46 drives several hinge seats to move through the sliding ring 45. The hinge seats drive the insertion rod 40 to slide inside the fixed tube 41 through the connecting rod 43. After one end of the insertion rod 40 is inserted between the teeth on the inner side of the stop gear 39, the output end of the electric cylinder 47 stops extending, so that the inner roll 11 and the outer roll 22 are fixedly connected. At the same time, the insertion rod 53 separates from the fixed seat 54. Then, while the first motor 18 drives the inner roll 11 to rotate, the outer roll 22 rotates accordingly, so that the outer roll 22 winds up the hose.

[0040] Simultaneously, the piezoresistive pressure sensor 33 monitors the hose pressure in real time. If the pressure exceeds the threshold, the piezoresistive pressure sensor 33 sends a signal to the control unit. The control unit immediately calculates the avoidance trajectory and, through inverse kinematics calculation, coordinates the second hollow shaft servo motor 38 driving the end joint to actively swing the rotating rod 34 and the hinge rod 35 down by a certain angle, providing avoidance space for the hose. After the pressure returns to normal, the system automatically resets or prompts for manual intervention. This mechanism utilizes the elastic deformation of the traction rope 36 to absorb impact and avoid rigid damage.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
