Description
Technical Field
The utility model provides a boats and ships fender convenient to installation is fixed, impact strength is high belongs to boats and ships articles for use technical field.
Background
At present, a fender device adopted on a ship is an arch-shaped rubber device, and the structure of the fender device is that a buffer cavity is arranged in the arch-shaped rubber device, a bolt is arranged at the bottom of the arch-shaped rubber device, and then the whole arch-shaped fender device is fixed by welding the bolt on the edge of a ship body. But because the volume of cushion chamber is less among the arch rubber device, consequently when boats and ships berth, arch rubber device can not play fine cushioning effect, can not alleviate the huge impact force when boats and ships are leaned on the shore in the at utmost, cause the striking injury to the hull easily, and when welding on the hull through the bolt, do not set up the space between bolt and the hull, the connection face unevenness between bolt and the hull has been caused, the fastening is relatively poor, consequently arch rubber device is when receiving the striking, whole device can the atress inhomogeneous, direct influence the life and the result of use of product. Chinese patent CN 204489141U provides a connection structure of high strength fender, and the volume of cushion chamber in this patent accounts for 1/3 ~ 1/2 of fender body total volume, and the bottom of bolt hole is provided with the chamfer, and this utility model compares the beneficial effect that has in prior art to be: the utility model discloses a buffering is respond well, and the impact resistance is strong, and durable has protected the ship board effectively. However, the product still has the following defects in the actual use process: because the product is provided with the buffer cavity with a larger space, the buffer cavity can bring larger elastic buffer and reduce the weight of the product, but when the product is used for ship body with a larger tonnage, the buffer cavity is easy to be completely flattened, and a better shock resistance effect cannot be achieved.
Disclosure of Invention
The utility model provides a not enough among the prior art, provide a boats and ships fender based on expanded material fills, this fender is owing to be filled with polymer expanded material in its inner space intussuseption, consequently can tolerate the impact of bigger intensity to this fender simple installation.
Realize the utility model discloses the technical scheme that above-mentioned purpose adopted does:

when the section of the polyurethane elastomer is a rectangular non-closed annular structure, the position of the notch is positioned in the middle of the bottom surface, two steel core plates are arranged inside the bottom surface of the polyurethane elastomer, and the two steel core plates are respectively positioned on the left side and the right side of the notch; the polyurethane elastomer is uniformly distributed with vertically through mounting holes along the length direction, the mounting holes are provided with a left group and a right group, the steel core plate on the left side is provided with through holes which are in one-to-one correspondence with the mounting holes on the left group, and the steel core plate on the right side is provided with through holes which are in one-to-one correspondence with the mounting holes on the right group; the novel ship is characterized in that a bolt is arranged in the mounting hole, the bottom end of the bolt is fixed on the ship body through welding, the bolt penetrates through the bottom surface of the polyurethane elastomer and the through hole in the steel core plate, a nut is mounted at the top of the bolt and screwed, and the polyurethane elastomer is fixed on the ship body through the bolt and the nut.
And a right-angle groove for avoiding a crater between the bolt and the ship body is arranged at the opening of the mounting hole on the bottom surface of the polyurethane elastomer.
The bent parts at the left side and the right side of the top surface of the polyurethane elastomer are in arc transition.
Compared with the prior art, the utility model provides a boats and ships fender based on expanded material fills has following advantage: 1. the application provides a boats and ships fender adopts bilayer structure, and the skin is polyurethane elastomer shell, and inside packing polymer expanded material, both combine together, have both reduced the holistic weight of fender, can tolerate great impact force again. 2. Polyurethane elastomer in this application has two kinds of structures, and on first kind of structure passed through adhesive fixation in hull, the installation was fixed very portably, is applicable to the less boats and ships of displacement and uses. In the second structure, two steel core plates are arranged inside the bottom surface of the polyurethane elastomer, and meanwhile, bolts penetrate through the bottom surface of the polyurethane elastomer and through holes in the steel core plates to fix the fender, so that the connection between the fender and a ship body is very firm, and the fender is suitable for ships with large water discharge.
