Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically a protection device for the dock entrance gate slot of a ship. Background Technology

[0002] Ship docking and berthing are common ship maintenance projects. With the increasing complexity and diversity of ship maintenance and modification projects, shipyards are seeing a rise in ship modification and repair orders. Large ships such as drilling platforms, luxury cruise ships, and FPSOs face the risk of collision when docking for maintenance. Before entering the dock, ships are transported to the vicinity of the dock by tugboats. After the bow enters the dock, the ship is towed to the dock by a tugboat and then guided to the dock entrance using cables. During this process, extra-wide and extra-large ships are prone to colliding with the dock entrance gate. For ships, collisions may cause minor local deformation, which can be resolved by replacement. However, once the dock entrance gate is damaged, the watertightness of the dock gate after closure cannot be guaranteed, and repairs are difficult. If the dock gate cannot be closed, other ships will not be able to enter the dock for maintenance, which is very costly for shipyards. Utility Model Content

[0003] This utility model provides a protection device for the dock entrance gate slot of a ship, in order to solve the technical defects of the prior art.

[0004] To solve the above-mentioned technical problems, the present invention provides a ship docking gate protection device, comprising a rigid box with a right-angled triangular cross-section. The box includes longitudinal wall plates, transverse wall plates, and inclined wall plates. An elastic structure is fixed to the outer side of the transverse wall plates. The device also includes a mounting plate fixed to one end of the box, with lifting lugs and rigging matched with the lifting lugs. The box fits the dimensions of the gate slot. The box and the elastic structure are strong enough to withstand the extrusion force from the docking vessel. The deformation of the elastic structure after being extruded by the docking vessel is less than the rated deformation.

[0005] Specifically, the elastic structure is a rubber pad with a protrusion on one side of the door groove.

[0006] Specifically, there are two rubber pads, which are fixed to the outer side of the transverse wall panel in the horizontal and vertical directions.

[0007] Specifically, the rubber pad is secured by bolts and nuts.

[0008] Specifically, the rubber pad is fixed by bonding.

[0009] Specifically, rubber sheets are attached to the longitudinal wall of the dock.

[0010] Specifically, the interior of the box is reinforced with a flat steel liner.

[0011] Specifically, the flat steel liner is welded to the inclined wall panel of the box body using a plug welding method.

[0012] Specifically, the rigging is equipped with shackles.

[0013] Specifically, the rigging consists of two steel wire ropes, which are suspended in two states: one tight and one loose.

[0014] Because this device is installed between the dock gate and the docking vessel, the buffering force of the elastic structure offsets the squeezing force from the docking vessel, effectively preventing damage to the dock gate when ultra-wide or ultra-large vessels enter the dock. It not only solves the difficulties in protecting the dock gate but also saves time and workload in dock gate protection. This device is very easy to assemble and disassemble; it can be quickly installed when needed and quickly removed after use, resulting in high reusability and strong practicality.

[0032] like Figures 1 to 12 As shown, the present invention provides a ship docking entrance gate protection device 101, comprising a rigid box with a right-angled triangular cross-section. The box includes longitudinal wall plates 2, transverse wall plates 3, and inclined wall plates 4. An elastic structure is fixed to the outer side of the transverse wall plates 3. It also includes a mounting plate 1 fixed to one end of the box, with lifting lugs 5 and rigging 104 matched to the lifting lugs 5. The box fits snugly with the gate slot 102. The box and elastic structure are strong enough to withstand the compressive force from the docking vessel. The deformation of the elastic structure after being compressed by the docking vessel is less than the rated deformation. Before the ship enters the dock, according to… Figures 1-5After the dock entrance gate protection device 101 is manufactured, it is hoisted to the dock entrance gate 102 using a dock crane before the ship enters the dock. During hoisting, it is necessary to ensure that the horizontal rubber pad 6 and vertical rubber pad 11 of the dock entrance gate protection device 101 are in contact with the dock entrance gate 102, and that the rubber plate 8 on the dock entrance gate protection device 101 is in contact with the longitudinal wall of the dock. The lap plate 1 is then attached to the dock wall and wharf. The area of ​​the lap plate should avoid interfering objects at the dock entrance, depending on the different conditions of each dock. After inspection and approval, the lifting lug 5 on the dock entrance gate protection device 101 is attached to the dock wall and wharf using rigging 104 and shackles. The mooring bollard 103 is connected and fixed nearby; during dismantling, the lifting lug 5 is hooked onto the dock crane hook, and the connecting wire rope 104 between the mooring bollard 103 near the dock head and the lifting lug 5 on the dock entrance gate protection device 101 is released to dismantle it; the dimensions of the dock entrance gate protection device 101 and the dock entrance gate 102 are matched to ensure the fit of the dock entrance gate protection device after installation; the box body and elastic structure must have sufficient strength to withstand the squeezing force from the entering vessel; the elastic structure, after being squeezed, has a deformation amount less than the rated deformation amount to ensure the normal operation of the device 101; Figure 9 As shown, after installation, the lowest point of the dock entrance gate protection device 101 must be lower than the point of maximum width variation of the vessel at the lowest tide, and its height must be greater than the height of the vessel's outer bottom plate when entering the dock at low tide. This ensures full coverage protection for all types of vessels entering the dock and guarantees the usability of all types of vessels. This application provides a dock entrance gate protection device that not only provides excellent protection for the dock entrance of large and medium-sized vessels, but also is simple to manufacture, easy to install, and has high reuse value.

[0033] Specifically, the elastic structure is a rubber pad with a protrusion on one side of the door groove. The rubber pad has good elasticity and is durable. The protrusion can further increase the cushioning effect.

[0034] Specifically, there are two rubber pads, which are fixed to the outer side of the transverse wall panel in a horizontal and vertical manner. The two rubber pads are arranged in a vertical and horizontal manner to ensure that the protrusions are staggered, which can enhance stability.

[0035] Specifically, the rubber pad is fixed by bolts and nuts 7. The fixing bolts are made of high-strength stainless steel, which ensures a lifespan for repeated use while ensuring that the stress is met.

[0036] Specifically, the rubber pad is fixed by bonding, and the bonding force is even, which can enhance stability.

[0037] Specifically, a rubber sheet 8 is attached to the longitudinal wall of the dock entrance to protect the longitudinal wall of the dock entrance.

[0038] Specifically, the inside of the box is reinforced with a reinforcing plate 9 by means of a flat steel liner 10, which further enhances the strength of the box.

[0039] Specifically, the flat steel liner is welded to the inclined wall panel of the box body using a plug welding method to ensure welding strength.

[0040] Specifically, the rigging is equipped with shackles, which can improve work efficiency and reduce the dangers of manual operation.

[0041] Specifically, the rigging 104 consists of two steel wire ropes, which are suspended in two states, one tight and one loose. To prevent the taut steel wire rope from breaking due to excessive stress and deformation of the dock gate protection device, the suspension uses two steel wire ropes, one tight and one loose, to increase secondary protection.

[0042] The above description is merely an exemplary embodiment of this application and is not intended to limit the scope of protection of this application. The scope of protection of this application is determined by the appended claims.
