Technical Field
[0001] The invention belongs to the technical field of ocean engineering, and particularly relates to a sliding device for automatic alignment of a slip ring stack. Background Art
[0002] Single point mooring is one of the most commonly used mooring methods for floating production storage and offloading vessels (FPSOs) at present. Among different types of single point systems of FPSOs, the internal turret single point system is the most widely used. Among them, the detachable internal turret single point mooring system has strong anti-wind and wave resistance, simple maintenance, and the advantages of quick detachment and reconnection. The slip ring stack is installed on the top of the single point buoy and is connected to the riser through the emergency shutdown valve at its lower part. It is the core equipment of the FPSO single point mooring system and undertakes the transmission of media such as crude oil, natural gas, and production water, as well as signals such as electricity and optical fiber communication between the FPSO and the wellhead platform. During the detachment and reconnection of the single point mooring system, the slip ring stack needs to achieve its vertical lifting and horizontal movement through the sliding system.
[0003] In the prior art, the movement of the slip ring stack mainly relies on manual operation, that is, dragging the slip ring stack through a manual or electric hoist to achieve the movement of the slip ring stack, which not only consumes a large amount of manpower but also makes it difficult to guarantee the movement accuracy.
[0004] Therefore, it is urgent to design a sliding device for automatic alignment of the slip ring stack to solve the above-mentioned problems. Summary of the Invention

[0006] To achieve the above object, the specific technical solution of the sliding device for automatic alignment of the slip ring stack of the present invention is as follows: A sliding device for automatic alignment of a slip ring stack includes a main frame and an outer frame. The outer frame is arranged on the main frame. A lifting circular plate is abutted on the main frame. A jacking oil cylinder is arranged on the outer frame. The main frame is driven to move in the vertical direction through the jacking oil cylinder, so that the slip ring stack connected to the lifting circular plate moves up and down; a transverse hinge ear is arranged on the main frame, an outer frame hinge ear is arranged on the outer frame, and a transverse locking oil cylinder is connected between the outer frame hinge ear and the transverse hinge ear. The transverse locking oil cylinder drives the outer frame to move in the horizontal direction, so that the slip ring stack arranged on the main frame moves horizontally along with the outer frame.
[0007] Further, the main frame is arranged on a support beam, and a horizontal driving mechanism is connected to the main frame to enable the main frame to move along the length direction of the support beam.
[0008] Further, the horizontal drive mechanism is connected with a drive gear which meshes with the rack of the support beam. The drive gear rotates to horizontally move the main frame along the length direction of the support beam.
[0009] Further, the lateral hinge ear is fixedly arranged on the surface of the main frame, and an outer frame hinge ear corresponding to the lateral hinge ear is arranged on the outside of the outer frame.
[0010] Further, the inner frame is arranged inside the outer frame, and a fixing block is connected to the inner frame to fix the lifting round plate connected to the slip ring stack.
[0011] Further, the lifting round plate is screwed onto the slip ring stack.
[0012] Further, a jacking hinge ear is connected to the upper surface of the inner frame. The jacking hinge ear abuts against the jacking oil cylinder. The jacking oil cylinder drives the inner frame connected to the jacking hinge ear to move vertically, so that the slip ring stack connected to the lifting round plate moves in the vertical direction.
[0013] Further, a limiting block is connected to the outer frame. One end of the limiting block away from the outer frame is screwed onto the inner frame to limit the vertical movement of the inner frame.
[0014] Further, a drive arm connecting frame is vertically arranged on the main frame, and a drive arm of the slip ring stack is connected to the drive arm connecting frame.
[0015] Further, a plurality of drive arm connecting plates are arranged on the drive arm connecting frame, so that the drive arms of the slip ring stack are connected to the corresponding drive arm connecting plates.
[0016] The slip ring stack automatic alignment sliding device of the present invention has the following advantages: By driving the inner frame to rise through the jacking hinge ear, the limiting block can limit the moving amount. Meanwhile, the inner frame drives the lifting round plate and the overall slip ring stack connected thereto to complete the jacking action; the lateral locking oil cylinders are respectively connected to the lateral hinge ears on the main frame and the outer frame hinge ears on the outer frame. Driven by the lateral locking oil cylinders, the outer frame, the inner frame, the lifting round plate and the main structure of the slip ring stack are driven to achieve lateral movement and locking. The operation of this application is simple, the operation is reliable, and the precision is higher. It is used to realize the vertical lifting and horizontal movement of the slip ring stack, thereby ensuring the efficiency of the single point mooring system disconnection and reconnection operations.

[0021] Next, refer to the attached Figure 1 to the attached Figure 6 to describe the sliding device for automatic alignment of the slip ring stack of the present invention.
[0022] As Figure 1As shown in the figure, the sliding device for automatic alignment of the slip ring stack in the present invention includes a main frame 3 and an outer frame 6. The outer frame 6 is arranged on the main frame 3. A hoisting circular plate 2 is abutted on the main frame 3. A jacking oil cylinder 8 is arranged on the outer frame 6. The main frame 3 is driven by the jacking oil cylinder 8 to move in the vertical direction, so that the slip ring stack 18 connected to the hoisting circular plate 8 moves up and down. A horizontal hinge ear 9 is arranged on the main frame 3, and an outer frame hinge ear 15 is arranged on the outer frame 5. A horizontal locking oil cylinder 10 is connected between the outer frame hinge ear 15 and the horizontal hinge ear 9. The horizontal locking oil cylinder 10 drives the outer frame 6 to move in the horizontal direction, so that the slip ring stack 18 arranged on the main frame 3 moves horizontally along with the outer frame 6.
[0023] The inner frame 5 is driven to rise by the jacking hinge ear 7, and the limiting block 17 can limit the moving amount. At the same time, the inner frame 3 drives the hoisting circular plate 2 and the overall slip ring stack 18 connected thereto to complete the jacking action. The horizontal locking oil cylinder 10 is respectively connected to the horizontal hinge ear 9 on the main frame 3 and the outer frame hinge ear 15 on the outer frame 6. Driven by the horizontal locking oil cylinder 10, the outer frame 6, the inner frame 5, the hoisting circular plate 2 and the main structure of the slip ring stack 18 are driven to realize horizontal movement and locking. The operation of this application is simple, the operation is reliable, and the precision is higher. It is used to realize the vertical lifting and horizontal movement of the slip ring stack 18, so as to ensure the efficiency of the disconnection and reconnection operations of the single point mooring system.
[0024] Further, as Figures 1 to 5 shown in the figure, the main frame 3 is arranged on the support beam 13. A horizontal driving mechanism 11 is connected to the main frame 3 to enable the main frame 3 to move along the length direction of the support beam 13. The horizontal driving mechanism 11 is connected with a driving gear 12. The driving gear 12 meshes with the rack 14 of the support beam 13. When the driving gear 12 rotates, the main frame 3 moves horizontally along the length direction of the support beam 13. The horizontal hinge ear 9 is fixedly arranged on the surface of the main frame 3, and an outer frame hinge ear 15 corresponding to the horizontal hinge ear 9 is arranged on the outside of the outer frame 6.
[0025] In this embodiment, preferably, the main frame 3 is welded by steel plates. The horizontal driving mechanism 11 is installed at the front end of the main frame 3. A driving gear 12 is arranged on the horizontal driving mechanism 11. Driven by the horizontal driving mechanism 11, the driving gear 12 meshes with the rack 14 to realize the horizontal movement of the main frame 3 along the length direction of the support beam 13.
[0026] Among them, the support beam 13 is placed inside the hull and can support the entire sliding device of the slip ring stack 18. A rack 14 is arranged on the support beam 13. Driven by the horizontal driving mechanism 11, the driving gear 12 meshes with the rack 14 to realize the horizontal movement of the main frame 3.
[0027] A transverse hinge ear 9 is welded to the upper surface of the main frame 3. The transverse hinge ear 9 is connected to a transverse locking oil cylinder 10, and an outer frame hinge ear 15 is provided at a corresponding position on the outer side of the outer frame 6. The transverse locking oil cylinder 10 is respectively connected to the transverse hinge ear 9 on the main frame 3 and the outer frame hinge ear 15 on the outer frame 6. When the transverse locking oil cylinder 10 expands and contracts, the outer frame 6 can drive the main structure of the slip ring stack 18 to achieve transverse movement and locking.
[0028] Further, as Figure 2 and Figure 6 shown, the inner frame 5 is arranged inside the outer frame 6, and a fixing block 4 is connected to the inner frame 5 to fix the lifting circular plate 2 connected to the slip ring stack 18; the lifting circular plate 2 is screwed to the slip ring stack 18.
[0029] A lifting hinge ear 7 is connected to the upper surface of the inner frame 5. The lifting hinge ear 7 abuts against a lifting oil cylinder 8. The lifting oil cylinder 8 drives the inner frame 5 connected to the lifting hinge ear 7 to move vertically, so that the slip ring stack 18 connected to the lifting circular plate 2 moves in the vertical direction; a limiting block 17 is connected to the outer frame 6. One end of the limiting block 17 away from the outer frame 6 is screwed to the inner frame 5 to limit the vertical movement of the inner frame 5.
[0030] In this embodiment, the inner frame 5 is placed inside the outer frame 6, and a fixing block 4 is bolted to the inner plate of the inner frame 5. The fixing block 4 is used to fix the lifting circular plate 2 connected to the slip ring stack 18 by bolts. A lifting hinge ear 7 is provided on the upper surface of the inner frame 5. When the lifting oil cylinder 8 installed on the outer frame 6 is lifted, the lifting oil cylinder 8 supports the lifting hinge ear 7 and drives the inner frame 5 to move vertically, and further enables the lifting circular plate 2 to drive the slip ring stack 18 as a whole to move in the vertical direction.
[0031] Preferably, the limiting block 17 connected to the outer frame 6 limits the vertical movement position of the outer frame 6, and the limiting block 17 can move in the vertical direction; a lifting oil cylinder 8 is installed inside the outer frame 6, and the lifting oil cylinder 8 can lift the inner frame 5.
[0032] Further, as Figure 1 and Figure 6 shown, a driving arm connecting frame 1 is vertically arranged on the main frame 3. A driving arm 19 of the slip ring stack 18 is connected to the driving arm connecting frame 1; a plurality of driving arm connecting plates 16 are provided on the driving arm connecting frame 1, so that the driving arm 19 of the slip ring stack 18 is connected to the corresponding driving arm connecting plate 16.
[0033] In this embodiment, the driving arm connecting frame 1 is welded by steel plates. The driving arm connecting frame 1 is vertically arranged on one side of the main frame 3. A plurality of driving arm connecting plates 16 are uniformly arranged along the length direction of the driving arm connecting frame 1, and the driving arm connecting plates 16 are connected to the driving arm 16 of the slip ring stack 18.
[0034] The working principle of the sliding device for automatic alignment of the slip ring stack in this application is as follows: The support beam 13 is arranged in the single-point cabin at the bow of the FPSO, above the single-point buoy, and supports the entire slip ring stack 18 and the sliding device. When the slip ring stack 18 needs to be overhauled, it is driven by the jacking oil cylinder 8 installed inside the outer frame 6, which jacks up the jacking hinge ear 7 arranged on the upper surface of the inner frame 5, so that the slip ring stack is disengaged from the single-point buoy. Driven by the horizontal drive mechanism 11 installed at the front end of the main frame 3, the drive gear 12 meshes with the rack 14 to achieve horizontal movement, and the slip ring stack 18 can be moved to the designated position.
[0035] The sliding device based on the automatic alignment of the slip ring stack drives the inner frame 5 to rise through the jacking hinge ear 7, and the limit block 17 can limit the movement amount. At the same time, the inner frame 5 drives the hoisting circular plate 2 and the overall slip ring stack 18 connected thereto to complete the jacking action; the lateral locking oil cylinders 10 are respectively connected to the lateral hinge ear 9 on the main frame 3 and the outer frame hinge ear 15 on the outer frame 6. Driven by the lateral locking oil cylinders 10, the main structures of the outer frame 6, the inner frame 5, the hoisting circular plate 2 and the slip ring stack 18 are driven to achieve lateral movement and locking. This application is simple to operate, reliable in operation, and has higher precision. It is used to realize the vertical lifting and horizontal movement of the slip ring stack 18, thereby ensuring the efficiency of the disconnection and reconnection operations of the single-point mooring system.
