Description

Technical Field

[0001] The utility model relates to the technical field of ship buffer devices, in particular to a tire-type fender for a piling ship. Background Art

[0002] Current piling vessels typically use rubber fenders made of steel fenders and rubber tires secured by lashings to cushion the impact of collisions with docks or tugboats. However, as a buffer against complex impact loads and friction, fenders are susceptible to breakage, aging, and detachment. Once these damages occur, they must be immediately replaced and reinstalled. For piling vessels operating long distances and under tight deadlines, this is a frequent occurrence that is highly desirable to avoid.

[0003] For example, the patent "Anti-collision rubber fender" (CN206125361U) designs a new fender structure with two semicircular rubber layers and a hollow crescent-shaped buffer gap to improve the fender's energy absorption. However, this structure, which has excellent anti-collision performance, is not only difficult to manufacture and install, but also has insufficient wear resistance and adaptability. Once subjected to strong lateral friction, the outer rubber structure is easily deformed, worn, and even torn.

[0004] The patent "A Tire Fender Assembly and Vessel" (CN206954468U) uses multiple small chains to secure the tire fender. In principle, this method extends the fender's service life by uniformly applying force to the four small chains in all directions through a central fixed ring. However, this method requires four perforations in the tire. When the fender is subjected to friction and extrusion stress, the perforations act as prefabricated cracks, making crack propagation more likely and damaging the tire fender. Furthermore, if small chains are wrapped and tied externally to protect the tire, they are prone to friction and damage to the surface of the contacting object (ship, dock buffer device).

[0005] In summary, the existing technical conditions for the optimization of rubber fenders need to be further improved. Utility Model Content

[0006] In view of the above-mentioned technical problems existing in existing ship fenders, the purpose of the utility model is to provide a tire-type fender for piling ships, which controls the initial defects of the fender surface by reducing the perforation area. The embedded connecting parts are completely in contact with the inner wall of the tire fender, and are fixed to the outer plate of the hull with two small marine chains, so that the rubber tire can be evenly stressed. The two-point fixation method that retains the freedom of the fender is more conducive to the tire releasing the load through movement and elastic deformation, thereby extending the service life of the tire fender.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a tire-type fender for a piling ship, including a tire fender, an embedded connecting piece, two hull eye plates, two embedded eye plates, and two small marine chains. The embedded connecting piece is C-shaped and is fittedly arranged on the inner wall of the tire fender. The two embedded eye plates are symmetrically connected at both ends of the embedded connecting piece. The tire fender is provided with two openings corresponding to the embedded eye plates, and a pipe sleeve is provided at the opening. The two embedded eye plates are located inside the tire fender and extend outward along the pipe sleeve. The two hull eye plates are respectively fixed on the outer side plates of the hull, and the two ends of the two small marine chains are respectively connected to the hull eye plate and the embedded eye plate through a shackle.

[0008] Furthermore, after the two marine small chains are fixed, the angle between them is 70°.

[0009] Furthermore, the embedded eye plate is vertically connected to the embedded connector, the tire fender sidewall is completely close to the hull, and the force of the marine small chain is parallel to the embedded eye plate.

[0010] Furthermore, the embedded eye plate includes a C-shaped connector and a connector, the two free ends of the C-shaped connector are connected to the embedded connector, and the C-shaped connector is passed through the pipe sleeve, the connector is connected to the top of the C-shaped connector and extends outward along the pipe sleeve, and the connector is a plate-like structure with a connecting hole provided thereon for connecting with a small ship chain.

[0011] Furthermore, the pipe sleeve includes a liner and two liner plates. The liner is a cylindrical structure and is inserted into the opening of the tire fender. The two liner plates are annular structures and are respectively connected to the two ends of the liner. The liner is interference fit with the opening on the tire fender.

[0012] Furthermore, a water flow hole is provided at the lowest horizontal point of the tire fender sidewall.

[0013] Compared with the prior art, the tire-type fender for piling boats provided by the present invention has the following beneficial effects:

[0014] (1) The damaged perforation area on the tire fender surface is controlled to a minimum, thus reducing the possibility of crack propagation in the rubber material from the source as much as possible;

[0015] (2) The embedded connector is completely fitted with the inner wall of the tire fender and is fixed to the outer plate of the hull with two small marine chains. This allows the rubber tire to be evenly stressed. In the event of collision, extrusion and friction between ships or between ships and dock anti-collision devices, and the use of a two-point fixation method that allows the fender to retain freedom, it is more conducive to the tire releasing the load through movement and elastic deformation, thereby extending the service life of the tire fender.

[0016] (3) The simple connection method of chain, shackle and eye plate makes it easy and quick to manufacture, install, dismantle and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0026] See also Figure 1 , Figure 2 , which is a schematic structural diagram of a tire-type fender for a piling vessel provided by the present invention.

[0027] The tire-type fender provided by the utility model acts on the side outer plate of the ship to locally thicken and reinforce it, so as to offset the plate thickness loss caused by the friction between the fender and the outer plate of the ship.

[0028] As shown in the figure, the tire-type fender for a piling vessel provided by the present invention includes five components: a tire fender 100 , a pre-embedded connector 200 , two hull eye plates 300 , two pre-embedded eye plates 400 , and two small marine chains 500 .

[0029] The embedded connector 200 is C-shaped and is fitted on the inner wall of the tire fender 100.

[0030] Two embedded eye plates 400 are symmetrically connected to both ends of the embedded connector 200. The tire fender 100 is provided with two openings corresponding to the embedded eye plates 400, and a pipe sleeve 600 is provided at the opening. The two embedded eye plates 400 are located inside the tire fender 100 and extend outward along the pipe sleeve 600.

[0031] The two hull eye plates 300 are respectively fixed on the outer hull plate, and the two ends of the two marine small chains 500 are respectively connected to the hull eye plates 300 and the embedded eye plates 400 through shackles 700, so that the tire fender 100 is suspended on the outer hull plate.

[0032] Compared with the prior art, the tire-type fender for piling vessels provided by the present invention controls the damage and perforation area of the tire fender 100 surface to a minimum, thereby reducing the possibility of crack propagation in the rubber material as much as possible from the source, and avoiding the wear and tear of the surface of the ship and dock anti-collision device due to the small chain tied to the outside of the tire fender 100.

[0033] The embedded connector 200 is fully aligned with the inner wall of the tire fender 100 and secured to the outer hull plate with two small marine chains 500. This ensures uniform stress distribution on the rubber tire. This allows the tire to release applied loads through movement and elastic deformation, rather than relying solely on the tire fender 100 itself to absorb energy, thus extending the service life of the tire fender 100. This prevents collisions, squeezing, and friction between ships or between ships and dock anti-collision devices. This two-point fixation method, which allows the fender to move freely, helps the tire release applied loads through movement and elastic deformation, rather than relying solely on the tire fender 100 itself to absorb energy.

[0034] Furthermore, after the two marine small chains 500 are fixed, the angle between them is preferably 70°. Such a structure can reduce the stress concentration on the embedded connector 200.

[0035] The embedded eye plate 400 is vertically connected to the embedded connector 200, so that the sidewall of the tire fender 100 is completely close to the hull, ensuring that when only gravity is applied, the force on the marine chain 500 is parallel to the embedded eye plate 400, so that the embedded eye plate 400 is only subjected to positive tensile stress.

[0036] Specifically, the tire fender 100 is a rubber tire, and the embedded connector 200 is a C-shaped steel pipe with a steel plate welded at the end. The steel pipe is pre-embedded in the tire fender 100 and its surface is in contact with the tire fender 100.

[0037] The selection of the embedded connector 200 corresponding to the size of the tire fender 100 should be determined based on the thickness of the tire fender 100. The diameter of the embedded connector 200 should not be less than 20% of the thickness of the tire fender 100. It should also not be too large, as this would make the inlay process difficult. The length of the embedded connector 200 should be an arc that is one-quarter of the circumference of the tire fender 100, and then determined based on the tire fender 100 diameter and then bent.

[0038] When selecting the small marine chain 500, the forces at the connection locations must be estimated. This solution prioritizes the B19 type small marine chain with a safe working load of 2.5t. Taking into account the diameter and thickness of the tire fender 100, the embedded eye plate 400, hull eye plate 300, and shackle 700, all with a safe working load of no less than 2.5t, are selected.

[0039] The hull eye plate 300 is provided on the outer hull plate for connecting the tire fender 100 . The hull eye plate 300 is a conventional steel plate and has an opening structure thereon. The opening is used for connecting with the small ship chain 500 .

[0040] like Figure 3 , Figure 4 The embedded eye plate 400 is connected to the embedded connector 200. The embedded eye plate 400 includes a C-shaped connector 410 and a connector 420. The two free ends of the C-shaped connector 410 are preferably welded to the embedded connector 200, and the C-shaped connector 410 is passed through the pipe sleeve 600. The connector 420 is connected to the top of the C-shaped connector 410 and extends outward along the pipe sleeve 600. The connector 420 is a plate-like structure with a connecting hole 421 provided thereon for connecting with the ship's small chain 500.

[0041] Further, if Figure 1 The pipe sleeve 600 includes a liner 610 and two liner plates 620. The liner 610 is a cylindrical structure and is inserted into the opening of the tire fender 100. The two liner plates 620 are annular structures and are respectively connected to the two ends of the liner 610. The outer diameters of the two liner plates 620 are larger than the diameter of the opening on the tire fender 100. The liner 610 and the opening on the tire fender are interference fit, which can prevent the liner 610 from falling off from the opening. The setting of the liner 610 can prevent the tire fender 100 from direct contact with the marine chain 500, reduce wear, and thus increase service life.

[0042] Both ends of the ship's small chain 500 are connected to shackles 700 , one end of the ship's small chain 500 is connected to the hull eye plate 300 through the shackle 700 , and the other end is connected to the embedded eye plate 400 through the shackle 700 .

[0043] The above-mentioned marine small chain 500 and shackle 700 are conventional existing technologies and will not be described in detail here.

[0044] Furthermore, a water flow hole 800 is provided at the lowest point of the sidewall of the tire fender 100 , and water accumulated in the tire fender 100 can be discharged through the water flow hole 800 .

[0045] The following examples illustrate the working process of the present invention in a specific application. It should be noted that the content described below is only a specific application example of the present solution and does not constitute a limitation to the present solution.

[0046] (1) First, determine the required diameter, thickness and installation height requirements of the tire fender 100 according to the molded depth and design draft of the pile driving vessel;

[0047] (2) Based on the above data, design the local thickening range of the hull side plate to prevent wear and tear, and determine the installation position of the hull connection eye plate 300. According to the angle requirements, determine the size of the embedded connector 200 and the welding position of its embedded eye plate 400. At the same time, determine the opening position and size of the tire fender 100 so that the opening and the embedded connector 200 at the root of the embedded eye plate 400 have a moderate interference fit;

[0048] (3) First, prefabricate two holes on the tire fender 100 and install the pipe sleeve 600;

[0049] (4) Welding the embedded eye plate 400 to the embedded connector 200, and embedding the entirety of the eye plate 400 into the tire fender 100, so that the embedded eye plate 400 passes through the opening;

[0050] (5) Use the shackle 700 to connect the two small ship chains 500 to the hull eye plate 300 and the embedded eye plate 400 respectively to complete the fixation.
