Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protector for a chain net of a pneumatic fender, and more particularly, to a part of the chain net which covers an outer peripheral surface of a pneumatic fender body. It relates to a protector for a chain net.

[0002]

2. Description of the Related Art Conventionally, pneumatic fenders moored on a quay or the like are provided with a plurality of pneumatic fenders so that the outer peripheral surface of the main body of the pneumatic fenders is not damaged by friction with the quay or contact with the hull. The tire is covered by a chain net connected via a chain. However, the body of the pneumatic fender is not damaged, and the durability can be enhanced.On the other hand, the chain net comes into contact with the quay and hull, so if the tires that make up the chain net are damaged and the chain is exposed, There is a problem that the outer peripheral surface of the pneumatic fender body is damaged or the surface of the hull is damaged through the chain.

[0003]

[Problems to be solved by the invention]
If the tire is damaged and the chain is exposed, it would be costly to replace the entire chain net, so only the damaged tire was replaced. As a method of replacing the tire, for example, a floating pneumatic fender body is first unloaded and air is removed from the fender body. Then, the chain net is partially disassembled, or the chain is gas-cut, and the damaged tire is removed. Then, a new old tire having a chain insertion hole formed in the tread portion is mounted via the chain. After that, the disassembled portion of the chain is connected via a shackle or the like, and high-pressure air is again injected into the pneumatic fender body, and then returned to sea or water.

[0004] However, as described above, there is a problem that tire replacement requires a lot of trouble and time, and that work at sea cannot be performed, and the cost becomes high. This idea was devised focusing on such conventional problems.
When the tire is damaged and the chain is exposed, the exposed chain can be easily repaired by covering the exposed chain with an elastic sheet member. It is an object of the present invention to provide a protector for a chain net of a pneumatic fender that can be performed.

[0005]

In order to achieve the above object, the present invention provides two chains covering the upper and lower surfaces of the chain at the intersection of the chain and the chain exposed on the surface of the pneumatic fender body. The gist is to provide a protector comprising an elastic sheet member and a fastening member for fastening around the two elastic sheet members sandwiching the chain.

[0006] Further, by providing a protective levee covering the periphery of the fastening member at a position where the fastening member of the elastic sheet member is attached,
The pneumatic fender body can be prevented from being damaged by the fastening member, and the elastic sheet member is made of a rubber sheet in which a reinforcing layer is embedded, so that the strength is strong, and in particular, a part of the conveyor belt is used. Thus, it can be manufactured at low cost.

[0007]

The present invention is configured as described above, and the upper and lower surfaces of the chain and the upper and lower surfaces of the crossing portion of the chain exposed on the surface of the pneumatic fender body are sandwiched between two elastic sheet members. By arranging in this manner and fastening the periphery with a fastening member, the exposed portion of the chain can be easily repaired, work can be easily performed on sea and water, and work can be performed at lower cost.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view of a pneumatic fender body 1 embodying the present invention, and 2 is a pneumatic fender body 1.
The chain net 2 covers a plurality of old tires 3 at predetermined intervals.
Are connected via

Reference numeral 5 denotes a chain 4 which is exposed on the surface of the pneumatic fender body 1 and a protector attached to the intersection X of the chain 4. This protector 5 is shown in FIG.
As shown in FIG. 3, two elastic sheet members 6a and 6b covering the upper and lower surfaces of the chain 4 and the intersection X, for example,
A rubber sheet of a conveyor belt containing a reinforcing layer, and two elastic sheet members 6 sandwiching the chain 4 and the intersection X
a, 6b and fastening members 7 such as bolts and nuts for fastening around the periphery.

As shown in FIGS. 4 and 5, upper and lower end portions 7a and 7b of the fastening member 7 are attached to the elastic sheet members 6a and 6b at positions where the fastening members 7 are fastened around the elastic sheet members 6a and 6b. 6b is provided with a protection dike 8 covering the periphery of the fastening member 7 so as not to be exposed from the surface of the protection dike 8b.
Is made of the same material as the elastic sheet members 6a and 6b, as shown in FIG. 5, and attached to the attachment position of the fastening member 7 of the elastic sheet members 6a and 6b via an adhesive or the like. As shown in FIG. 6, a protective embankment 8a having a concave cross section having an insertion hole 9 in the center may be formed in advance, and may be fixed together with the protective embankment 8a when the fastening member 7 is tightened and fixed.

As described above, in the case of the present invention, when the old tire 3 constituting the chain net 2 is damaged and the chain 4 is exposed, the damaged old tire 3 is removed, and the old tire 3 is removed. Two elastic sheet members 6a, 2b are provided on the upper and lower surfaces of the exposed portion of the chain 4 and the intersection X of the chain 4.
6b, as shown in FIG.
Then, the surroundings of the fastening member 7 are protected via protection dikes 8 and 8a.
As a result, the intersection X of the chain a and the chain 4 is not directly exposed on the outer peripheral surface of the pneumatic fender body 1, so that the surface of the pneumatic fender body 1 is not damaged, and The exposed portion of the chain a can be easily repaired, work can be easily performed on the sea and on the water, and the work can be performed at lower cost.

Further, in the embodiment of the present invention, the elastic sheet members 6a and 6b are not specially manufactured, but can be manufactured at low cost by using, for example, waste materials of the conveyor belt, and can be temporarily maintained. However, it can sufficiently replace old tires.

[0013]

According to the present invention, two elastic sheet members covering the upper and lower surfaces of the chain are provided at the intersection of the chain and the chain exposed on the surface of the pneumatic fender body as described above, Since a protector comprising a fastening member for fastening the periphery of two elastic sheet members sandwiching the chain is provided, when the tire is damaged and the chain is exposed, the exposed chain portion is covered with the elastic sheet member and fastened. It can be easily repaired by tightening and fixing with members, and the cumbersome setup work like replacing old tires is no longer necessary, and the pneumatic fender body at the site, that is, at sea or on the water, was floated. The installation work can be done easily and in a short time in the state, the installation work cost can be greatly reduced, and the elastic sheet member is not specially manufactured. Also can be a powerful and inexpensive to manufacture in strength by fabricated utilizing wastes, etc., there is an effect that can be instead of sufficiently old tires be a temporary maintenance.

[0014] Further, since the protective levee that covers the periphery of the fastening member is provided at the position where the fastening member of the elastic sheet member is attached, the fastening member is not directly exposed to the outer peripheral surface of the pneumatic fender body. There is an effect that the surface of the main body of the fender is not damaged, and the fastening operation can be easily performed.
