Description

[Detailed description of the invention] (Technical field) The technical content described in this specification regarding the support device for floating type fenders is mainly applied to mooring of vessels on the floating side (for example, a fishing boat to a fishing boat). In many cases, it is suspended from the deck of a mother ship above the sea surface to provide a buffer during a sea accident, and is suitable for use as protection against sea water, but it can also be used, of course, at places such as seaside quays. ,
This invention relates to the improvement of the suspension support mechanism for so-called floating type fenders, and is generally positioned in the field of technology related to fenders or ship protection.

Problems Generally, floating type fencing materials are made by injecting air into a cord-reinforced rubber gas bag molded into a bale-like external shape, and more preferably by injecting closed-cell polyethylene foam similar to the above-mentioned gas bag. The main body of the fencing material covered with a rubber outer skin is surrounded by a holding net having a mesh formed along its outer periphery, and the holding net has a plurality of attachment chains between the end of the main body of the fencing material and the mounting fittings in contact with the main body of the fencing material. Usually, by attaching a hanging cable to this mounting bracket,
It is used to hang from and lift from a ship.

The mounting hardware conventionally includes a board, a parent rib in its diametrical direction, and sometimes a plurality of auxiliary ribs in the radial direction that serve to reinforce these ribs. A hole for attaching the cable is drilled. Therefore, since the shafts used to connect the board and the mounting chain are oriented flat along the radial direction of the main body of the shielding material, they come into narrow local contact with the outer surface of the end of the main body, and excessive external force is applied. As a result, the shackle does not work freely, making it difficult to attach and detach the attachment chain.Furthermore, when the attachment chain loosens and the attachment fittings shift due to the deformation of the shielding material due to the contact load, the shackle does not work freely. There were various problems such as scratching and damaging the outer surface of the main material.

Purpose of the invention In order to solve the above-mentioned problems, the purpose of this invention is to provide a support device for a floating type fender in which the connection structure of the mounting chain to the mounting bracket is devised.

(Structure of the device) The above purpose is advantageously achieved by a system that has the following points as its main points.

A support device for a floating type fencing mainly for ships, in which a main body of fencing having a bale-like external appearance is suspended by a holding net that surrounds the outer periphery of the fencing with a mesh, and a plurality of mounting chains and mounting fittings. The free ends of the plurality of mounting chains connected to the main body of the bracing material are connected to the main ribs on the diameter and the sub-ribs on the radius provided on the base plate of the mounting bracket which are in contact with the end of the main body of the shielding material. A support device for a floating type fencing material, which is made up of a diametrically connected main rib with a swivel joint for hanging.

As mentioned above, the mounting holes, which are opened not in the board but at a distance from the board in each of the diametrical main rib and the radial sub-rib, allow the shackle passed through the mounting hole to come into contact with the outer surface of the end of the main body of the shielding material. This eliminates the damage caused by contact and the inconvenience of attachment and detachment, and the suspension swivel connected to the main rib on the diameter can rotate freely with respect to the suspension rope with the retaining net mainly made of fencing material. Therefore, disadvantages due to twisting of the suspension support device are advantageously reduced.

(Explanation of the illustrated example) Fig. 1 shows the external appearance of the mounting bracket 1 to which the improvement based on this invention has been applied, in which 2 is the substrate, 3 is the diametrical main rib, 4 is the radial sub-rib, and 5 and 6 are the mounting brackets, respectively. It is a hole.

Although one radial sub-rib 4 is shown sandwiching the diametrical main rib 3, two or more radial sub-ribs 4 may be provided.

The mounting holes 5 and 6 of each rib 3 and 4 are connected to a shackle to be mounted to these (when an end ring 7, which is hypothetically shown in the illustrated example, is used to connect the end shackle of a mounting chain, which will be explained later). However, since the ring 7 may be directly connected and the ring 7 may be omitted, at least half the width of the connecting tool (end ring or shackle) adjacent to the shackle (including the end ring 7) is connected to the board. The openings are arranged in such a manner that they are spaced apart from each other.

Another mounting hole 8 at the end of the diametrical main rib 3
is opened, and connected to a chain 11 as a suspension cable via a shackle 9 via a shackle 12, which is freely rotatable, and a swivel joint 10.

As shown in FIGS. 2 and 3, this mounting bracket 1 consists of a main body of fencing material 13 prepared so as to have a bale-like appearance, and a mesh on its outer periphery, for example, a generatrix line and a peripheral line as shown in the figure. A retaining net 17 designed to surround an array of chains 14, 15 intersecting along the chain with a lattice of annular rubber 16 (for example a car tire) placed at their intersection points.
The above-mentioned suspension support is achieved by connecting the free ends of the plurality of attachment chains 18 connected to the end ring 7 shown in FIG. 1 with a shackle, for example. Note that 19 in the figure is a protective rubber tube.

The main body 13 of the barrier material has a core made of a laminated structure of closed-cell foam, which can be made of polyethylene, and is usually covered with a rubber outer skin of 10 to 20 mm, and this rubber outer skin is preferably made of nylon 66. By embedding and reinforcing organic fiber cords with multiple plies in a static angle arrangement, the length can be 800 to 6,500 mm with an external diameter of 300 to 3,300 mm, and the length can be longer if necessary. , can be created arbitrarily.

(Effect of the invention) According to this invention, in order to connect the free end of the attachment chain provided on the holding net of the main body of the fencing material to the mounting bracket that corresponds to the latch of the hanging support of the floating type fencing material, the end of the main body We have specially prepared mounting holes drilled in the diametrical main rib and the radial sub-rib at an appropriate distance from the substrate in contact with the part, so that the shackle as a connecting member will not rub strongly against the outer periphery of the end of the main material. This eliminates damage and handling disadvantages caused by this, and since a swivel joint for suspension is connected to the main rib on the diameter, reliable suspension support is advantageous without causing kinks in the suspension cable. will be fulfilled.
