Description

Technical Field

[0001] This invention relates to the field of berthing buffer technology, specifically a buffer device for berthing of FPSO high-pile berths. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations. Ships have different technical performance, equipment, and structural types according to different usage requirements. Ships are a man-made means of transportation that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small boats are called boats or dinghies. They are collectively referred to as ships or dinghies. At the docks where ships are moored, there are usually some buffer devices installed to buffer the impact of ships against the shore. These devices can prevent the hull from violently impacting the dock and protect the hull and the shore from damage due to the impact.

[0003] Currently, most of the buffer devices on the shore of some docks are made of discarded tires and are placed at equal intervals. This creates blind spots in the buffer area within a certain distance, which fails to meet the needs of all-round buffering. In addition, some of the current buffer devices push the ship outward, leaving a large gap between the ship and the embankment, which poses a certain risk when the crew goes ashore. Summary of the Invention

[0028] 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.

[0029] Please see Figure 1-7 As shown, a buffer device for FPSO high-pile berth berth includes a high-pile berth 1 for berthing. A fixed toothed plate 2 is fixed to one side of the surface of the high-pile berth 1. Several guide rails 3 are fixed to the surface of the high-pile berth 1. A housing 4 slides on the surface of the guide rails 3. A housing 5 is fixed to the surface of the housing 4. A moving mechanism 6 is provided in the inner cavity of the housing 5 for movement. Gears 7 that mesh with the fixed toothed plate 2 are provided on the surface of the moving mechanism 6. A limiting shell 8 is fixed in the inner cavity of the housing 4. Several buffer rods 9 slide in the inner cavity of the limiting shell 8. A back plate 10 is fixed to one end of the buffer rod 9. One side of the buffer rod 9 passes through the back plate 10. An outer buffer mechanism 11 is provided on the surface of the back plate 10. The surface of the buffer rod 9 is provided with... The inner buffer mechanism 12 has a connecting block 13 fixed to the other end of the buffer rod 9. The surface of the connecting block 13 is provided with a transmission mechanism 14 for transmission, and the surface of the transmission mechanism 14 is provided with a connecting plate 15. When in use, the outer buffer mechanism 11 and the inner buffer mechanism 12 can buffer the impact on the hull, thereby achieving the purpose of protecting the high-pile dock 1 and the hull. In addition, the staff can use the moving mechanism 6 to change the position of the outer shell 4 and the housing 5 as needed, thereby adapting to the buffering needs of different positions. Furthermore, when the hull is completely moored, the connecting plate 15 can be flipped under the action of the transmission mechanism 14 and contact the side of the ship, thereby facilitating the crew to disembark and improving practicality.

[0030] The moving mechanism 6 includes a motor 61, which is fixed to the inner cavity of the housing 5. The output shaft of the motor 61 is fixed with a drive shaft 62. Several belt drive components 63 are fixed to the surface of the drive shaft 62. A driven shaft 64 is fixed to the other side of the belt drive component 63. A gear 7 is fixed to the surface of the driven shaft 64. In this embodiment, through the arrangement of the motor 61, drive shaft 62, belt drive component 63 and driven shaft 64, the operator can use the motor 61 to make the drive shaft 62 rotate under the action of the motor 61, thereby driving the belt drive component 63 to work. Under the drive of the belt drive component 63, the driven shafts 64 on both sides start to drive the gear 7 to rotate, thereby making the gear 7 mesh with the fixed tooth plate 2, so that the outer shell 4 and the housing 5 start to move.

[0031] Motor 61 is a servo motor and has a built-in brake device. In this embodiment, this setting makes the rotation of motor 61 more precise, and under the action of the brake device, the gear 7 can be stably stopped at the specified position.

[0032] The external buffer mechanism 11 includes a hinge 111. One end of the hinge 111 is fixed to one end of a buffer rod 9 on one side. The other end of the hinge 111 is rotatably equipped with a buffer plate 112. A smooth roller 113 is rotatably equipped on the surface of the buffer plate 112. A first spring 114 is fixed on both sides of the surface of the buffer plate 112. The other end of the first spring 114 is fixed to the surface of the back plate 10. In this embodiment, through the arrangement of the hinge 111, the buffer plate 112, the smooth roller 113 and the first spring 114, when the buffer plate 112 is impacted, the buffer plate 112 can be deflected under the action of the hinge 111. Then, with the assistance of the first spring 114, the impact at certain angles can be resolved. Furthermore, the smooth roller 113 can guide the hull.

[0033] There are several smooth rollers 113, which are arranged at equal intervals on the surface of the buffer plate 112. In this embodiment, this arrangement increases the overall contact area between the smooth rollers 113 and the hull, thereby further improving the buffering effect of the outer buffer mechanism 11.

[0034] The inner buffer mechanism 12 includes a slide rod 121 and a fixing plate 122 fixed to the surface of the buffer rod 9. One end of the slide rod 121 is fixed to the surface of the limiting shell 8, and a second spring 123 is sleeved on the surface of the slide rod 121. One end of the second spring 123 is fixed to the surface of the limiting shell 8, and the other end of the second spring 123 is fixed to the surface of the fixing plate 122. In this embodiment, by setting up the slide rod 121, the fixing plate 122, and the second spring 123, when the buffer rod 9 slides, the fixing plate 122 fixed to the surface of the buffer rod 9 can buffer the sliding of the buffer rod 9 under the action of the second spring 123, thereby further improving the buffering capacity of the device.

[0035] The transmission mechanism 14 includes a threaded block 141, which is fixed to one side of the surface of the connecting block 13. A threaded rod 142 meshes with the inner cavity of the threaded block 141. A driving transmission gear 143 is fixed to the other end of the threaded rod 142. A driven transmission gear 144 meshes with the surface of the driving transmission gear 143. A first transmission rod 145 is fixed to the inner cavity of the driven transmission gear 144. A second transmission rod 146 is driven onto the surface of the first transmission rod 145 via a bevel gear set. A connecting plate 15 is fixed to the surface of the second transmission rod 146. In this embodiment, the threaded block 141, threaded rod 142, driving transmission gear 143, and driven transmission gear 144 mesh together. 44. The arrangement of the first transmission rod 145 and the second transmission rod 146 allows the threaded block 141 and the threaded rod 142 to mesh when the connecting block 13 moves the threaded block 141. This causes the threaded rod 142 to rotate, and the active transmission tooth 143 fixed to the threaded rod 142 can drive the driven transmission tooth 144 to rotate. This causes the first transmission rod 145 and the second transmission rod 146 to rotate, and the connecting plate 15 fixed to the surface of the second transmission rod 146 can flip over. When the buffer rod 9 is fully compressed, the connecting plate 15 can flip over half a turn to achieve the purpose of connecting with the hull.

[0036] The active transmission gear 143 and the driven transmission gear 144 have different specifications. In this embodiment, this arrangement makes the flipping angle of the connecting plate 15 and the travel distance of the buffer rod 9 match each other, thereby improving the practicality of the device.

[0037] A protective shell 16 is fixed to one side of the outer shell 4. The first transmission rod 145 rotates in the inner cavity of the protective shell 16. In this embodiment, the protective shell 16 provides support for the operation of the transmission mechanism 14, improves the stability of the transmission mechanism 14 when it rotates, and provides protection for the operation of the active transmission gear 143 and the driven transmission gear 144.

[0038] The connecting block 13 fits into the inner cavity of the limiting shell 8 to slide. In this embodiment, this arrangement improves the stability of the connecting block 13 when it moves, thereby improving the stability of the buffer rod 9 when it is working.

[0039] Working principle: When a ship is observed approaching the high-pile pier 1, the operator can use the moving mechanism 6. Under the action of the motor 61, the driving shaft 62, the belt drive component 63, and the driven shaft 64, the gear 7 and the fixed tooth plate 2 are engaged, thereby causing the outer shell 4 and the guide rail 3 to move, so that the position of the device is suitable for the position of the ship.

[0040] When the hull approaches, it can come into contact with the outer buffer mechanism 11. Then, under the action of the hinge 111, buffer plate 112, smooth roller 113 and first spring 114, the compression of the hull is initially buffered, and some of the forces with different movement angles from the buffer rod 9 can be relieved. Furthermore, under the action of the inner buffer mechanism 12, the buffering capacity of the device is further improved.

[0041] Furthermore, if the ship wishes to moor alongside this device, the crew can fully compress the outer buffer mechanism 11, causing the outer buffer mechanism 11 to move the buffer rod 9. This, in turn, causes the connecting block 13 to drive the transmission mechanism 14. Under the action of the threaded block 141, threaded rod 142, driving transmission gear 143, driven transmission gear 144, first transmission rod 145, and second transmission rod 146, the connecting plate 15 rotates. When the buffer rod 9 is fully compressed, the connecting plate 15 rotates half a turn, allowing the connecting plate 15 to rest on the ship's hull, thus facilitating the crew's movement.
