Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering construction, specifically to a modular adaptive anti-collision device for berthing piers. Background Technology

[0002] At locks / ship lifts, navigation walls, and wharves, berths serve as crucial hydraulic structures for berthing, mooring, and buffering against ship impacts. Their safety and reliability directly affect navigation efficiency, ship safety, and the safety of the main structure (such as gates and lock walls).

[0003] When ships pass through locks, the flow conditions change significantly due to the flushing and discharge of water. For navigational safety, other ships should usually anchor and wait while the preceding ship passes through. To improve lock throughput, berthing piers are installed between the anchorage and the lock for ships to temporarily berth before entering the lock. Berthing piers are either single-sided or double-sided; single-sided piers allow ships to berth on only one side, while double-sided piers allow ships to berth on both sides. Typically, each lock corresponds to one berthing pier.

[0004] Most mooring bollards are embedded in the bottom of the vessel using pre-embedded parts, extending all the way to the water surface, and then a mooring bollard is installed on top to facilitate vessel operation.

[0005] Anti-collision components are installed on the outer wall of the berth, which can effectively prevent damage to the outer wall of the berth when the ship is docked, and also prevent the paint on the outer wall of the ship from being scratched off, thus playing a role in buffering and preventing collisions.

[0006] However, existing anti-collision components for berths have significant drawbacks: most consist of a single anti-collision plate made of corrosion-resistant rubber, with a simple structure; some small ports even use discarded tires directly strapped to the berths for cushioning. Because the buffer components and anti-collision plates are an integral structure, the entire assembly must be replaced after long-term use; even if some components are still usable, they cannot be retained individually, resulting in serious cost waste. Furthermore, the disassembly and installation of this integral structure is cumbersome, requiring 3-5 auxiliary tools and typically 2-3 people to operate, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a modular design, easy disassembly and assembly, and excellent cushioning effect for berths to solve the problems existing in the current technology. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a modular adaptive anti-collision device for berthing piers.

[0008] This invention is achieved through the following technical solution:

[0010] The anti-collision assembly includes an anti-collision plate, guide rods, and a first spring. Two guide blocks are fixed at the top of the mounting bracket. The guide rods slide through the guide blocks. The anti-collision plate is fixed between the two guide rods. Several grooves are provided on the side wall of the anti-collision plate. The first spring is fixed in the groove. A slider is slidably connected in the groove. A rotatable ball is embedded in the side wall of the slider.

[0011] The buffer connection assembly includes a buffer plate, a spring cylinder, and a hinge rod. The buffer plate is slidably sleeved on the vertical rod of the mounting frame. A corrosion-resistant buffer rubber pad fixed on one side of the buffer plate is in contact with the berthing pier. A spring cylinder is inserted into the first arc-shaped positioning block of the buffer plate. A T-shaped slide rod extends into the second arc-shaped positioning block of the anti-collision plate. The spring cylinder and the T-shaped slide rod are connected by a second spring, a connecting rod, a collar, and a cross-hinged hinge rod. The spring cylinder is provided with a second spring and a limiting ring.

[0012] Preferably, the buffer plate is made of hard alloy material, the buffer rubber pad is completely attached to the outer wall of the pier, and the buffer rubber pad is made of seawater corrosion resistant material.

[0013] Preferably, a sealing block is embedded at the top of the spring cylinder, and a through hole is provided on one side of the bottom end. The diameter of the through hole is smaller than the inner ring diameter of the limiting ring, and the limiting ring is fixed in the middle section inside the spring cylinder.

[0014] Preferably, the hinge rods are movably connected at their cross joints via hinge pins, and both ends of the hinge rods are rotatably fitted to the connecting rods via collars, with the collars and connecting rods having a clearance fit.

[0015] Preferably, the balls are evenly distributed on the outer wall of the anti-collision plate, and the slider corresponding to each ball slides against the inner wall of the groove, and the slider is fixedly connected to the first spring.

[0016] Preferably, the top two sides of the concrete pouring slab are arc-shaped, the limiting protrusion of the mounting plate is tightly fitted with the side wall of the concrete pouring slab, and the bolts pass through the concrete pouring slab and the mounting plate in sequence to achieve fixation.

[0017] Preferably, one end of the T-shaped slide rod extends into the second arc-shaped positioning block and fits against the inner wall of the positioning block, while the other end is fixedly connected to the second spring, and the end of the second spring away from the T-shaped slide rod is fixed to the limiting ring.

[0018] Preferably, the sealing block and the top of the spring cylinder are detachably sealed together, and the sealing block is provided with a through hole, the diameter of which is larger than the diameter of the through hole at the bottom of the spring cylinder.

[0019] Preferably, the outer wall of the ball is covered with a rubber layer.

[0020] The method for installing and dismantling the modular adaptive berthing block anti-collision device is characterized by including the following operations:

[0021] Overall installation: Slide the mounting bracket over the pier, and use the arc-shaped structure at the top of the concrete slab to guide the mounting plate between the two concrete slabs. After pre-positioning by the limiting protrusion, fix it with bolts; hold the hinge rod tightly to compress the second spring using leverage, insert the spring cylinder into the first arc-shaped positioning block, so that the T-shaped sliding rod extends into the second arc-shaped positioning block, and release the hinge rod to complete the assembly.

[0022] Complete disassembly: Unscrew the fixing bolts and use hoisting machinery to lift the mounting frame away from above the pier;

[0023] Component replacement: Grip the hinge rod to compress the second spring, remove the component to be replaced, open the sealing block to drain the seawater, and replace the spring cylinder or the second spring. Reinstall the spring cylinder and T-shaped slide rod according to the assembly steps in operation (a).

[0024] Compared with existing technologies, the beneficial effects of this invention are: the device, by setting up anti-collision plates and several secondary spring cylinders, increases the multi-level buffering and anti-collision effect, while making the disassembly of anti-collision plates and each spring cylinder very convenient and simple, and can recover costs to a certain extent; at the same time, it is equipped with structures such as hinge rods, which can make the spring cylinders easy to disassemble and install by levering the lever effect without other auxiliary tools, and the whole installation can be completed by using the mounting plate and two concrete pouring plates, which is more time-saving and labor-saving to operate.

[0025] Compared with the prior art, the present invention has the following significant advantages:

[0026] 1. Excellent multi-level buffering and anti-collision effect: Through the elastic buffering of the first spring, the secondary elastic buffering of the second spring, and the seawater damping buffering, a three-level buffering structure is formed, which can significantly reduce the impact force of the ship and effectively protect the main structure of the berthing pier and the safety of the ship. At the same time, the design of the ball bearings and rubber layer prevents the ship's paint from being scratched.

[0027] 2. Modular design for easy assembly and disassembly: Core components such as anti-collision plates and spring cylinders adopt a modular design. Through the cooperation of arc-shaped positioning blocks and hinge rods, individual assembly and disassembly can be achieved without additional auxiliary tools, saving time and effort and avoiding the cost waste caused by replacing the whole unit.

[0028] 3. Stable connection and strong adaptability: The mounting frame is fixed to the concrete slab through the limiting fit of the mounting plate and the bolt, so the connection is stable and reliable; the buffer plate is made of hard alloy material and corrosion-resistant buffer rubber pad, which is suitable for the harsh seawater environment of water conservancy hubs, and the modular structure can flexibly adjust the component specifications according to the size of the berthing pier and the tonnage of the ship to adapt to different application scenarios.

[0029] 4. Long service life: The seawater damping effect prevents the second spring from being compressed instantly. Combined with the use of corrosion-resistant materials, it effectively extends the service life of each component of the device and reduces maintenance frequency and cost.

[0030] The present invention has a reasonable structural design that takes into account buffer performance, ease of assembly and disassembly, and durability, effectively solving many defects of existing anti-collision components for berthing piers. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0035] like Figure 1 , Figure 2 As shown, a modular adaptive berthing block anti-collision device includes a berthing block 1, on which a mounting frame 2 is fitted. The mounting frame 2 consists of two U-shaped plates and multiple vertical rods. The two U-shaped plates are fitted onto the berthing block 1 and slidably connected thereto. The multiple vertical rods are fixedly connected to the two U-shaped plates by bolts, which facilitates the overall installation and disassembly. Disassembly can be completed by directly lifting it off from above using hoisting machinery. During installation, it can be directly fitted onto the berthing block 1 from above, making the operation simple.

[0036] The top of the pier 1 is equipped with a mooring bollard 3 and two concrete slabs 4. The top of the mounting frame 2 is fixedly equipped with an mounting plate 5. The mounting plate 5 has limiting protrusions on both sides. The mounting plate 5 is inserted between the two concrete slabs 4 and the mounting plate 5 is fixedly connected to the two concrete slabs 4 by bolts. The top sides of the two concrete slabs 4 are arc-shaped to facilitate the insertion of the mounting plate 5. The limiting protrusions can fit against the sides of the concrete slabs 4, thereby playing a limiting and locking role. The connection is ensured to be stable by bolts.

[0037] Two guide blocks 6 are fixedly installed at the top of the mounting bracket 2. Each guide block 6 has a slidingly connected guide rod 7 inserted into it. A crash plate 8 is fixedly connected between the two guide rods 7. Several grooves 9 are provided on the side wall of the crash plate 8. A first spring 10 is fixedly installed in the groove 9. A slider 11 is slidably connected in the groove 9. A rotatable ball bearing 12 is embedded in the side wall of the slider 11. The outer wall of the ball bearing 12 is covered with a rubber layer. During operation, the ship first contacts the crash plate 8. The rotating ball bearing 12 can effectively reduce contact with the paint surface of the ship's outer wall, avoiding scratches and paint damage. The first spring 10 can effectively buffer the impact, preventing excessive force from damaging the outer wall of the ship or the ball bearing 12, thus successfully completing the buffering work.

[0038] A buffer plate 13 is installed on the mounting frame 2. The buffer plate 13 is fitted onto multiple vertical bars and slidably connected to them. The buffer plate 13 is set on one side of the pier 1. The buffer plate 13 is made of hard alloy material. A buffer rubber pad is fixedly installed on one side of it. The buffer rubber pad is made of corrosion-resistant material and is fitted to the pier 1 to further improve the buffering effect and at the same time make the force distributed by multiple vertical bars.

[0039] Multiple first arc-shaped positioning blocks 14 are fixedly installed on the side wall of the buffer plate 13. A spring cylinder 15 is inserted into each first arc-shaped positioning block 14. A T-shaped slide rod 20 is slidably connected inside the spring cylinder 15. Multiple second arc-shaped positioning blocks 21 are fixedly installed on one side wall of the anti-collision plate 8. One end of each T-shaped slide rod 20 extends into the corresponding second arc-shaped positioning block 21. A second spring 18 is provided inside the spring cylinder 15. When the anti-collision plate 8 is subjected to force, it will compress the second spring 18, which will play a secondary buffering role and improve the buffering effect.

[0040] A limiting ring 17 is fixedly installed inside the spring cylinder 15. A sealing block 16 is fixedly embedded at the top of the spring cylinder 15, and the sealing block 16 is detachably sealed to the top of the spring cylinder 15. The sealing block 16 has a through hole, the diameter of which is larger than the diameter of the through hole at the bottom of the spring cylinder 15. The second spring 18 is disposed between the limiting ring 17 and the T-shaped slide rod 20. A through hole 19 is fixedly provided on one side of the bottom end of the spring cylinder 15, the diameter of which is smaller than the inner ring diameter of the limiting ring 17. After the ship contacts the device, the pressure is transmitted to the spring cylinder 15, causing the second spring 18 to compress. Due to the sealing of the sealing block 16, the seawater filled inside the spring cylinder 15 is squeezed downwards, and the small diameter of the through hole 19 causes the seawater to drain slowly, forming a seawater damping buffer effect, which can prevent the second spring 18 from compressing instantly and indirectly extend its service life. When disassembling, the sealing block 16 can be opened to quickly drain the internal seawater, avoiding slow compression that may affect operation.

[0041] The bottom end of the spring cylinder 15 and the bottom end of the corresponding T-shaped slide rod 20 are both fixedly connected to a connecting rod 22. Each connecting rod 22 is fitted with a collar 23, and each collar 23 is movably connected to a hinge rod 24. The corresponding two hinge rods 24 are arranged crosswise, and the crosswise connection is hinged by a hinge pin. When installing and removing the spring cylinder 15, the operator grasps the corresponding two hinge rods 24 and squeezes them tightly. Using the leverage effect, the second spring 18 is compressed, which allows the spring cylinder 15 to disengage from the first arc-shaped positioning block 14 and the T-shaped slide rod 20 to disengage from the second arc-shaped positioning block 21. After removal, a new second spring 18 or spring cylinder 15 is replaced, and the above steps are repeated to reinstall it for use.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
