Description

Technical Field

[0001] The invention belongs to the field of hull protection devices, and in particular relates to a ship dock buoy fixing device and a use method thereof. Background Art

[0002] Generally speaking, shipbuilding is divided into two conventional stages: the dock stage and the wharf stage. As one of the most important infrastructures of a shipyard, the wharf plays an important role in the shipbuilding process. Usually, when a ship is docked at a wharf, it is not in direct contact with the wharf, because the position of the ship will change with the rise and fall of the tide. If the ship is in direct contact with the wharf, the outer plate of the ship will be damaged. Therefore, the shipyard usually sets up a buoy at the wharf to separate the wharf from the ship. The buoy is a rubber product with a soft material. The buoy is used for buffering, so that the outer plate of the ship is not affected during the ebb and flow of the tide.

[0003] During the construction of shipyard docks, considering the need to set up buoys, channel steel and other embedded parts are usually embedded in the dock platform to facilitate welding with the fixed float eye plate. However, this method has a relatively fixed position of the float, and the embedded parts of the dock platform are corroded over time and cannot meet the requirements for float fixation, which will cause risks in float fixation. At the same time, dock platforms in various places differ in material and form due to climate, geography and other considerations. Fixing with embedded parts requires prior planning and calculation, and cannot be adjusted after setting. In the actual use of ships when they need to berth, the position of the ship needs to be adjusted to accommodate the position of the embedded parts on the dock platform, and the water area of ​​the dock cannot be reasonably utilized.

[0004] In addition, during the mooring process, ships often need to be fixed to the bollards on the dock with cables. However, the location of the bollards on the dock and the size of the ship itself require the path and angle of the cables to ensure that the actual force on the cables does not exceed the maximum stress bearing capacity of the cables. Due to the influence of factors such as wind and waves in the mooring environment, the cables will swing and cause friction with the dock platform, which may lead to breakage, resulting in safety hazards such as unstable mooring of the ship, damage to mechanical equipment, and casualties.

[0005] Therefore, it is urgent to design and innovate a ship dock buoy fixing device and a method of using the same to solve the above problems. Summary of the invention

[0060] Example

[0061] like Figures 1 to 5 As shown, a floating ball fixing device for a ship dock and a method for using the same, the floating ball fixing device 5 includes a fixing slot 51 and a cable protection assembly 52; the fixing slot 51 includes a front side plate, an upper side plate and a rear side plate, and is in an inverted U shape, for being inserted into a dock platform 22, a fixing ear plate 511 is vertically provided on the front end surface of the front side plate, and a safety ear plate 512 is vertically provided on the upper end surface of the upper side plate; the cable protection assembly 52 is installed on the rear end surface of the rear side plate, for avoiding wear caused by friction between the cable bollard 31 and the end surface of the dock platform 22, thereby providing a smooth transition of the cable bollard 31 and the cable 32, the cable protection assembly 52 includes a protection card plate 522 and a protection round tube 521, and the protection round tube 521 is arranged at the rear end of the protection card plate 522.

[0062] The method of use comprises the following steps:

[0063] S1. When installing the buoy fixing device 5 for the first time at any dock 21, first determine the size and quantity of the buoys 1 and the prepared installation positions of each buoy 1 at the dock 21 according to the hull size of the ship to be berthed and the safety distance requirements between berths, so as to ensure that the buoys 1 can float stably at any tide level and ensure that there are enough buoys 1 to provide buffer when the ship is docked.

[0064] S2. Determine the number of the buoy fixing devices 5 to be provided on one side of a single buoy 1 according to the size of the buoy 1 and the wind, wave and current environment, and fix at least one buoy fixing device 5 at both ends of the single buoy 1, thereby providing sufficient force to stabilize the buoy 1, ensuring that the buoy 1 can effectively bear the weight of the hull and the dynamic load of the liquid surface at the dock 21, while adapting to different environmental conditions.

[0065] The wind, wave and current environment includes but is not limited to typhoons, tidal flow velocity, and ocean current direction, all of which will affect the stability of the buoy 1. Specifically, during the typhoon season, wind and waves will exert a huge impact force on the buoy 1. Changes in tidal flow velocity will affect the vertical force of the buoy 1. The direction of the ocean current will affect the horizontal force of the buoy 1. Therefore, by adding devices on both sides of the buoy 1, the stability and safety of the buoy 1 under extreme climatic conditions can be improved. When the size of the buoy 1 is larger, the lateral spacing between the buoy 1 and the dock platform 22 is larger. At this time, the large buoy 1 is subjected to greater horizontal forces in the wind and waves, and more fixed points are required to provide additional support. By adding devices, the stability of the buoy 1 when fixed can be increased. Furthermore, the anchor chain connected to the buoy 1 by the added device can be installed on the dock platform 22 in a cross-setting manner. The cross-setting anchor chains can distribute the force more evenly, reducing the risk of a single anchor chain breaking due to excessive force, thereby improving the stability of the buoy 1.

[0066] S3, sequentially installing each float fixing device 5 on the float 1.

[0067] S3-1. Fix one end of the first anchor chain 41 and the second anchor chain (the second anchor chain is not shown in the figure) to the fixed ear plate 511 and the safety ear plate 512 of the same float fixing device 5 respectively through a shackle, and fix the other ends of the first anchor chain 41 and the second anchor chain to the hanging ear on the same side of the single float 1 through a shackle, that is, one end of the first anchor chain 41 is fixed to the fixed ear plate 511 of the float fixing device 5, the other end of the first anchor chain 41 is fixed to one side of the float 1, one end of the second anchor chain is fixed to the safety ear plate 512 of the float fixing device 5, and the other end of the second anchor chain is fixed to the other side of the float 1, and repeat the operation until the connection between the two sides of the single float 1 and each float fixing device 5 is completed.

[0068] The length of the first anchor chain 41 is determined according to the high and low water level range of the wharf 21, ensuring that the force on the first anchor chain 41 is less than the strength of the anchor chain itself when the buoy 1 is at the lowest water level at low tide, preventing the first anchor chain 41 from being pulled and broken, ensuring that it will not be too loose when the tide reaches the highest water level, and ensuring that the first anchor chain 41 can limit the buoy 1 from turning over the wharf platform 22 under the expected wave height. The length of the second anchor chain is greater than the distance from the far end of the shackle on the insurance ear plate 512 to the central axis of the buoy 1. It is advisable to keep the second anchor chain in a relaxed state during installation, so as to ensure that there is no force between the second anchor chain and the fixed point of the buoy 1 when the first anchor chain 41 is straightened. When the first anchor chain 41 is broken at the fixed ear plate 511, the second anchor chain is forced to pull the buoy 1, thereby preventing the buoy 1 from being separated from the buoy fixing device 5, and adding a safety measure between the buoy 1 and the wharf platform 22.

[0069] S3-2, repeat step S3-1 to complete the fixed connection of each float fixing device 5 on the float 1 in sequence.

[0070] S4. According to the prepared setting position of the buoy 1 at the dock 21 determined in step S1, the buoy 1 is simultaneously hoisted and moved to the dock 21 through the buoy fixing devices 5 combined at both ends of the buoy 1, and the buoy fixing device 5 combined with the buoy 1 is fixed on the dock platform 22, and the fixed connection between the buoy fixing device 5 and the dock platform 22 is completed in sequence.

[0071] S4-1. According to the prepared installation position of the buoy 1 at the dock 21 and the axial length of the buoy 1 determined in step S1, the fixed position of each buoy fixing device 5 on the dock platform 22 is determined, and a positioning mark line is drawn at the fixed position. The preferred fixed position is on the vertical plane where the end face shackle hanging point of the buoy 1 is located, so that the first anchor chain 41 in a taut state after hanging coincides with a plane perpendicular to the ground.

[0072] S4-2, when lowering, first drop the buoy 1 on the water surface outside the dock platform 22, then adjust the device position so that the buoy fixing device 5 falls on the positioning mark line. At this time, if the first anchor chain 41 and / or the second anchor chain are too long to contact the water surface, the height of the buoy 1 is adjusted by adjusting the fixed position of the buoy fixing device 5 on the dock platform 22, thereby changing the height of the lowest point on the first anchor chain 41 and the second anchor chain. Specifically, by translating the buoy fixing device 5 to both sides to adjust the height of the buoy 1, the lowest point on the first anchor chain 41 and the second anchor chain is higher than the water surface, so as to avoid the first anchor chain 41 and / or the second anchor chain from being corroded due to long-term immersion in seawater.

[0073] S4-3, fixing the floating ball fixing device 5 on the dock platform 22 through the fixing slot 51.

[0074] (1) In this embodiment, the cable protection assembly 52 is welded and fixed to the rear side plate. The distance between the inner side surfaces of the front side plate and the rear side plate on the fixing slot 51 is slightly larger than the thickness of the dock platform 22. When fixing, the fixing slot 51 is completely lowered until it is embedded in the upper end of the dock platform 22. The device relies on its own weight and the gravity of the buoy 1 to achieve a stable fixation with the dock platform 22, which simplifies the structure of the device to the greatest extent and is suitable for the case where the upper end surface of the dock platform 22 has a regular shape. By increasing the length of the front side plate and the rear side plate, that is, deepening the depth of the fixing slot 51, the stability between the device and the dock platform 22 can be further improved.

[0075] (2) In another embodiment, the rear side plate is provided with a fastening bolt hole 5131, and the fastening bolt hole 5131 is symmetrically provided along the center line of the rear side plate. When fixing, after the fixing slot 51 is inserted into the upper end of the dock platform 22, the fastener is inserted into the fastening bolt hole 5131 and tightened, thereby locking and fixing the device to the dock platform 22, which can adapt to the upper end surface thickness of various dock platforms 22. That is, step S4-3 specifically includes: inserting and tightening the fastener into the fastening bolt hole 5131, thereby locking and fixing the device to the dock platform 22.

[0076] (3) In other embodiments, based on (1) or (2), the float fixing device 5 further includes an elastic member 53, and the elastic member 53 is arranged between the fixing slot 51 and the dock platform 22. The elastic member 53 is molded by the local dock platform 22, and the inner side surface of the elastic member 53 has a shape matching the dock platform 22, and the outer side surface of the elastic member 53 has a shape matching the inner side surface of the fixing slot 51. When the elastic member 53 is inserted into the upper end of the dock platform 22, the left and right end faces of the elastic member 53 are naturally perpendicular to the dock platform 22. Therefore, the elastic member 53 can replace the marking operation of the positioning mark line, so that there is a more obvious positioning adjustment reference during lifting and coordination, and the position can be adjusted by translation according to actual conditions after installation, which is more flexible than the marked positioning mark line. At the same time, the elastic member 53 also increases the stability and adaptability between the fixed card slot 51 and the upper end of the dock platform 22, making the device more widely applicable. In addition, it also avoids the damage to the dock platform 22 caused by direct friction between the device and the dock platform 22.

[0077] Specifically, step S4-1 and step S4-2 are replaced as follows:

[0078] S4-1, according to the prepared installation position of the buoy 1 at the dock 21 and the axial length of the buoy 1 determined in step S1, the fixed position of each buoy fixing device 5 on the dock platform 22 is determined, and the elastic member 53 is sleeved at the fixed position.

[0079] S4-2, when lowering, first drop the buoy 1 onto the water surface outside the dock platform 22 , then adjust the position of the buoy fixing device 5 so that the buoy fixing device 5 is clamped on the elastic member 53 .

[0080] S4-3, fixing the floating ball fixing device 5 on the dock platform 22 through the fixing slot 51.

[0081] S5, repeating steps S3 to S4 until the fixed connection of the float fixing device 5 on each float 1 is completed, and each float fixing device 5 combined with the float 1 is installed in place on the dock platform 22.

[0082] S6. When a cable 32 is arranged between the ship to be berthed and the mooring pile 31 of the dock 21, and there is interference between the cable 32 and the dock platform 22, the cable protection assembly 52 is fixedly installed on the floating ball fixing device 5 located in the interference path of the cable 32 according to the interference position between the cable 32 and the dock platform 22, so that the cable 32 contacts the outer wall of the protective circular tube 521 in the cable protection assembly 52, and a smooth transition is provided for the cable 32 through the smooth surface of the protective circular tube 521, so that the cable 32 can be prevented from being worn and damaged by continuous friction with the end face of the dock platform 22 during the swinging process of the cable 32 under the influence of wind and waves, and the safety risk of the cable 32 breaking and making the ship unstable is reduced. At the same time, by adjusting the distance between the protective circular tube 521 and the rear side plate, the contact point between the cable 32 and the protective circular tube 521 can be changed, thereby changing the setting angle of the cable 32. Through calculation, the load on the cable 32 can be effectively reduced, and the stability of the ship berthing can be increased.

[0083] (a) In this embodiment, the cable protection assembly 52 includes a protection round tube 521 and a protection card plate 522. The cable protection assembly 52 is fixed to the rear side plate of the fixed card slot 51 by welding, and the protection round tube 521 and the protection card plate 522 are also fixed by welding. Therefore, the distance between the protection round tube 521 and the rear side plate is achieved by selecting the length of the protection card plate 522 before welding. In addition, in order to ensure a stable connection between the protection round tube 521 and the protection card plate 522, a trimming groove 5211 is opened on the front end side wall of the protection round tube 521 according to the thickness of the protection card plate 522. The trimming groove 5211 has a notch that matches the thickness of the protection card plate 522. The preferred specific steps include:

[0084] S6-1. First, the protection card plate 522 is vertically welded to the rear side plate of the fixed card slot 51, so that the long side of the protection card plate 522 is set to be perpendicular to the interference path direction of the cable 32, so as to avoid additional pressure generated when the oblique force is applied.

[0085] S6-2. Then, the protection round tube 521 is inserted into the long side of the protection clamping plate 522 through the trimming groove 5211, so that the long side end surface of the protection clamping plate 522 is against the inner wall of the protection round tube 521 to provide a stronger supporting force.

[0086] S6-3. The position of the protective circular tube 521 is adjusted by sliding the protective circular tube 521 along the long side direction of the protective card plate 522 until the protective circular tube 521 is connected to the cable 32. The protective circular tube 521 is welded and fixed to the protective card plate 522 so that the force of the cable 32 is transmitted to the protective card plate 522 and the device through the connection point, and then the force is dispersed by using the dock platform 22 connected to the device.

[0087] (b) In another embodiment, the fixed slot 51 also includes an adjustment base 5132, the adjustment base 5132 is fixed to the rear side plate, a plurality of adjustment holes 5133 are formed on the adjustment base 5132, the cable protection assembly 52 includes a protection tube 521, a protection card plate 522 and an adjustment bolt 5221, the protection tube 521 and the protection card plate 522 are fixed as a whole, an adjustment bolt 5221 is fixed on the rear end surface of the protection card plate 522, the adjustment bolt 5221 has an external thread matching the internal thread of the adjustment hole 5133, and the cable protection assembly 52 is threadedly connected to the adjustment hole 5133 on the adjustment base 5132 through the adjustment bolt 5221. When the height of the dock platform 22 and the height of the cable 32 on the mooring bollard 31 are different, and the traction angle of the cable 32 needs to be changed, the vertical height position of the protective round tube 521 can be adjusted to assist in completing the adjustment of the setting angle of the mooring bollard 31 and the cable 32, while avoiding the limitation of the position of the mooring bollard 31 on the dock 21 and the berthing position. The specific steps include:

[0088] S6-1. According to the interference path between the cable 32 and the dock platform 22, select a suitable adjustment hole 5133 to ensure that the height of the cable protection assembly 52 is located on the interference path so that the cable 32 can pass through the outer wall of the protective tube 521 to avoid direct friction between the cable 32 and the dock platform 22.

[0089] S6-2. Align the adjusting bolt 5221 with the adjusting hole 5133. By adjusting the depth of the adjusting bolt 5221 in the adjusting hole 5133, the distance between the protective tube 521 and the rear side plate can be adjusted, thereby changing the angle of the cable 32, dispersing the force of the cable 32 itself, and reducing the force at the fixed points at both ends of the cable 32, thereby improving the berthing stability of the ship.

[0090] S6-3. Further, the adjusting bolt 5221 in the adjusting hole 5133 is rotated to adjust the orientation angle of the cable protection assembly 52 so that the protection tube 521 is tangent to the cable 32 , thereby reducing the stress on the cable protection assembly 52 .
