Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pneumatic fender for fixing a quay, and more specifically, a pneumatic type that can replace only a fender main body when the fender main body is damaged or an air leak occurs. It relates to fenders.
[0002]
[Prior art]
Conventionally, as shown in FIGS. 3 to 6, a pneumatic fender for fixing a quay is hollow by sequentially laminating an inner layer rubber 1, at least one reinforcing layer 2 (reinforcing cord layer), and an outer layer rubber 3. A fender main body 4 formed in a cylindrical shape, a quay fixing fixing plate 5 attached to both ends of the fender main body 4 and a receiving plate mounting plate 6 for receiving a receiving plate are added. It is configured integrally by sulfur molding.
[0003]
When the pneumatic fender is fixed to the quay G or the like, it is arranged so that an annular flange plate 7a covered with rubber is attached to one end of the fender main body 4 via a fixing plate 5. It is installed and fixed by a fastening member 8 such as a bolt, and is arranged so that the other end of the fender body 4 is sandwiched by an annular flange plate 7b covered with rubber via a receiving plate mounting plate 6. Then, it is fixed by a fastening member 8 such as a bolt. Reference numeral 9 denotes a stopper provided in the air chamber of the fender main body 4.
[0004]
[Problems to be solved by the invention]
However, the conventional fenders as described above cannot replace only the fender main body 4 when the fender main body 4 is damaged or air leakage occurs during use. There is a problem that the mounting fixing plate 5 including the fender main body 4 and the receiving plate mounting plate 6 must all be replaced, and there is a problem that it becomes very expensive. However, all of the fender main body 1 must be lifted to the land, transported to a factory, etc., and repaired. .
[0005]
The object of the present invention is that only the fender main body can be exchanged, and the mounting fixing plate and the receiving plate mounting plate can be diverted, so that they can be exchanged at low cost, and on-site restoration work can be easily performed. The object is to provide a pneumatic fender.
[0006]
[Means for Solving the Problems]
Pneumatic fender of the present invention for achieving the above Symbol object, an inner layer rubber, fender body formed by molding at least one layer of reinforcing layers, and sequentially laminating the outer layer rubber hollow cylinder,-proof In the pneumatic fender made up of mounting fixing plates and receiving plate mounting plates provided at both ends of the main body, the fender main body, mounting fixing plate and receiving plate mounting plate can be divided. The bead portion is formed by folding back a reinforcing layer at both ends of the fender body, and the bead portion is formed so as to wrap the bead portion from the inside at the inner peripheral edge of the mounting fixing plate and the receiving plate mounting plate. A L-shaped cross-section holding metal fitting, and a triangular cross-section holding metal fitting that presses the bead portion from the outside, the triangular cross-section inclined surface facing the L-shaped cross-section holding metal fitting, L-shaped holding bracket and triangular section By a pressing metal fitting, detachable bead portion of the fender body, and to hermetically hold constituting, the mounting fixing plate, fender is brought into contact with the outer surface of the triangular cross section of the retainer member The gist is to provide a rubber-like elastic stopper ring for preventing over compression of the main body .
[0007]
The present invention is configured as described above, and only the fender main body can be replaced, so that even when the fender main body is damaged or air leakage or the like occurs, Since the armor plate can be used again to reassemble the fender body, the replacement cost can be reduced and the on-site restoration work can be easily performed.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
In addition, the same component as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description.
1 is a cross-sectional view of a pneumatic fender embodying the present invention, FIG. 2 is an enlarged cross-sectional view of a main part of FIG. 1, and a fender main body 14 includes an inner rubber layer 1, at least one reinforcing layer 2 (Reinforcing cord layer) and outer layer rubber 3 are sequentially laminated to form a hollow cylinder, and the end portion of the fender main body 14 is folded to form a bead portion 10.
[0009]
On the other hand, on the inner peripheral edge of the fixing plate 5 for fixing the quay, a holding metal fitting 11a formed in an L-shaped cross section so as to wrap the bead portion 10 from the inside, and a triangular cross section for pressing the bead portion 10 from the outside. A presser fitting 11b is provided.
[0010]
Although not shown in the drawings, a presser fitting 11a formed in an L-shaped cross section so as to wrap a bead portion 10 similar to that provided on the mounting fixing plate 5 from the inner side at the inner peripheral edge portion of the receiving plate mounting plate 6; A pressing metal fitting 11b having a triangular cross section for pressing the portion 10 from the outside is provided.
[0011]
Then, the bead portions 10 provided at both ends of the fender body 14 are detachably and airtightly held by the pressing metal fittings 11a and 11b provided on the mounting fixing plate 5 and the receiving plate mounting plate 6. It is configured.
[0012]
Further, a stopper ring 12 made of a rubber-like elastic body is provided outside the presser fitting 11b so as to prevent the fender main body 14 from being compressed or compressed. Further, instead of providing the inner layer rubber, a tube-shaped air bag can be provided inside the fender main body 14 and the airtight chamber 15 can be provided separately.
[0013]
As described above, the fender main body 14, the mounting fixing plate 5 and the impact plate mounting plate 6 are configured to be separable, the bead portions 10 are formed at both ends of the fender main body 14, and the mounting fixing plate 5. In addition, only the fender main body 14 is exchanged by providing the receiving plate 10 with the holding metal fittings 11a and 11b that can attach and detach the bead portion 10 of the fender main body 14 in an airtight manner. Is possible.
[0014]
Therefore, even when the fender main body 14 is damaged or air leaks due to breakage or the like, the fender main body 14 is assembled again by diverting the conventional fixing plate 5 and the receiving plate mounting plate 6. As a result, the replacement cost of the fender main body 14 can be reduced, and the restoration work at the site can be easily performed.
Further, by providing the stopper ring 12 made of a rubber-like elastic body on the outer side of the presser fitting 11b, it is possible to prevent the fender main body 14 from being compressed or compressed.
[0015]
【The invention's effect】
The present invention is configured so that the fender main body, the mounting fixing plate, and the impact plate mounting plate can be divided as described above, and a bead portion is formed by folding back a reinforcing layer at both ends of the fender body. In the inner periphery of the mounting fixing plate and the receiving plate mounting plate , there is provided a L-shaped holding metal fitting formed so as to wrap the bead portion from the inside, and a triangular cross section for pressing the bead portion from the outside. A pressing metal fitting is provided with a slope having a triangular cross-section facing the L-shaped pressing metal fitting, and the bead portion of the fender body is formed by the L-shaped holding metal fitting and the triangular holding metal fitting. Is removable and airtight, so that only the main body of the fender can be replaced, and the mounting fixing plate and the receiving plate mounting plate can be diverted. Also easily Ukoto can be.
[0016]
Further, by providing the mounting fixing plate with a stopper ring made of a rubber-like elastic body in contact with the outer surface of the holding metal fitting having a triangular section, it is possible to prevent the fender main body from being compressed or compressed.
