Description

[Detailed description of the invention] The present invention relates to an impact plate for fenders, and more specifically, to an impact plate for fenders in which an impact pad is fixedly mounted on the main body of the impact plate using bolts and nuts. .

Conventional fender impact plates have impact pads fixedly placed on the impact plate main body using nuts and bolts. This is a structure in which the impact receiving pad is fixed by drilling a hole in the impact receiving pad, passing a bolt through it from the impact receiving pad side, and screwing it into a nut on the fender side of the impact receiving plate main body (see Figures 1 and 2). .

The nuts on the fender side of the impact plate main body are welded to the main body (see Figure 2), but as a ship repeatedly comes alongside such an impact plate, the bolts (see Figure 2) 5) loosens and floats up, and even if the nut and bolt on the impact plate body side become unthreaded, the bolt is still supported by the insertion hole of the impact plate body and the impact pad, and the bolt head If the ship continues to protrude above the pad and comes alongside in that state, damaging the ship's side, the impact load of coming alongside may damage the pad or cause damage to the main body of the impact plate. There were problems such as damage to nuts on the fender side of the ship, and the entire impact plate had to be replaced.

In addition, with such impact plates, workability is difficult because nuts are fixed to the fender side of the body of the impact plate, and furthermore, the impact plate installed at the tip of the fender is heavy. One of the problems was that it caused the front of the fender to sag.

The impact plate for the fender according to the present invention eliminates this problem, and its gist is that the fender made of a rubber elastic body is provided protruding from the fender side, and is attached to the side of the fender. In a fender impact plate where the fender side of the impact plate main body is reinforced with a reinforcing material and the impact pad is fixedly placed on the side alongside the fender, the impact pad is attached to the main body of the fender. For fixed mounting, the main body and bolts are integrated on the side of the impact receiving plate main body, and the bolts of the integrated impact plate main body are inserted into the insertion holes provided in the impact receiving pad. Insert the
The impact plate of the fender has a structure in which the impact pad is fixedly placed on the impact plate main body by screwing nuts onto the bolts.

Hereinafter, the impact plate of the fender according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a fender 3 that is fixed to a shock absorbing pad 1 and a shock absorbing plate main body 2 with nuts and bolts, and is attached to a quay wall 4.
FIG. 2 is a partially cutaway side view showing the state in which the device is installed.

In the fender shown in FIG. 1, the impact pad 1 is conventionally attached to the impact plate body 2 by the method shown in FIG. 2.

That is, FIG. 2 shows the impact receiving pad 1 in the conventional impact receiving plate.
2 is a partial cross-sectional view showing a fixed state of the impact receiving plate main body 2, in which a bolt 5 is inserted from the side side into the insertion hole provided in the impact receiving pad 1 and the impact receiving plate main body, and the bolt and the impact receiving pad are inserted. The impact receiving pad 1 is fixed to the impact receiving plate main body part 2 by the bolt head on the side of the recess 6 provided in the impact receiving plate main body part 1 and the nut welded and fixed to the impact receiving plate main body part 2.

When ships are repeatedly brought alongside such fenders, the above-mentioned problems arise.

That is, the bolt 5 screwed into the fixing nut 8 on the fender side of the impact plate main body 2 becomes loose, the bolt 5 rises, and the head of the bolt 7 protrudes from the surface of the impact receiving pad.

Therefore, as mentioned above, if a ship comes alongside the impact plate of such conventional fenders, the ship's side may be damaged, the impact pad or bolts may be damaged, and the impact plate may need to be replaced. was there.

Moreover, when the bolt 5 comes off, it becomes possible to hold the impact pad 1 on the impact receiving plate main body 2.

FIG. 3 is a partial sectional view showing the fixed state of the impact pad and the impact plate body 2 in the impact plate of the fender according to the present invention and the structure of the impact plate main body. 1 and the impact plate main body part 2, the impact plate main body part 2 and the bolt part 5'
are made integrally, or are integrated by, for example, stud welding a bolt part 5' on the impact plate main body part 2,
The impact pad 1 is fixed to the impact plate main body 2 by the bolt portion 5' and the nut 7 located within the recess 6 of the impact pad 1.

Further, the outer circumferential surface of the bolt 5' which is in contact with the inner surface of the impact pad insertion hole is provided with a impact pad falling-off prevention 11 such as threads or knurls.

Since the impact plate of the fender according to the present invention has the above-described structure, even if the nut 7 loosens and falls off, the bolt 5' is integrated with the protection plate main body 2, so the bolt 5' It will not float up and damage the ship's side, and since the bolt 5' supports the impact receiving pad 1, it will prevent the impact receiving pad from falling off, and it will be able to adequately deal with coming alongside. The outer circumferential surface of the bolt 5' that is in contact with the inner surface of the pad insertion hole is provided with a shock absorbing pad drop prevention device 11, and since the shock absorbing pad is made of synthetic resin, rubber elastic material, etc., it is a protective pad. Interacting with the fall prevention 11, the impact receiving pad maintains a fixed state - it does not fall off easily and does not cause damage to the side of the ship.

FIGS. 4 and 5 are cutaway side views showing other embodiments of the bolt portion integrated with the main body of the fender in the impact plate of the fender according to the present invention, for example, the impact plate When stud welding the main body part and the bolt part, if there are burrs on the joint part, the fit with the impact pad will not be good, so if this happens, cut the end of the bolt part 5'' as shown in Figure 4. If the bolt is used in a location where there is a strong impact when joining the ship, the end of the bolt portion 5'' should be widened to increase the welding area as shown in FIG.

As detailed above, the impact plate of the fender according to the present invention is new and excellent, but in addition to the above-mentioned effects, the impact plate that directly receives the ship's side load is generally about 25φ. 70 to 200 bolts are used, and the weight is also large, but the one of the present invention has a nut fixed to the fender side of the main body of the impact plate and a bolt long enough to be screwed into the nut. It is unnecessary, and its weight ranges from 200 kg to 800 kg, and it has remarkable features such as being lightweight, eliminating the front sagging caused by the impact plate, and maintaining the performance of the fender.
