Description

[Detailed Description of the Invention] The present invention relates to a vane plate that is attached to the claw of an anchor to improve the holding power of the anchor.

Conventionally, pens or buoys for cultivating pearl oysters and yellowtail have been moored with harbor anchors.

However, commercially available harbor anchors have too small claws to hold onto the seabed where sand or mud has accumulated, resulting in insufficient holding power and the anchor cannot be moored in a fixed position.

Therefore, in order to increase the claw area and obtain sufficient holding power, an attempt was made to weld a separately manufactured wing plate to the anchor claw, but in this case, the fixed wing plate increased the weight and bulk of the anchor. requires significantly more effort.

Furthermore, when transporting the required number of anchors to the drop site by boat, the blades protruding from the claws may injure the crew, making it dangerous to walk on the ship, and the blades may damage the ship's hull. there were.

Furthermore, even if some external force is applied to the slats and the slats are bent and damaged, it is very time consuming to separate the slats from the welded parts, and it is extremely difficult to replace the slats. It turned out there was a problem.

The present invention focuses on the claw shape of commercially available anchors and provides an anchor blade that can solve the above-mentioned problems at once by making special improvements to the blade plate.

The present invention will be specifically described below based on embodiments shown in the drawings.

FIG. 1 shows a state in which the vane plate 2 of the present invention is attached to a commercially available two-claw anchor 1.

The claw 11 of the anchor 1 has a shape that gradually becomes wider on the tip side, and the thickness of the claw becomes thinner on the tip side.

The blade plate 2 is shaped by cutting an iron plate into a triangular shape, and is fixed to the claw 11 by overlapping with two fastening metal fittings 3, 3a.

The shape of the blade plate 2 and the number of fastening metal fittings 3 are not limited to those described above. For example, as shown in FIG. Of course, it is also possible to use two or more.

Two lines parallel to the base end side of the blade plate 2,
Two shaft holes on L5. 5a, 5b,
Establish 5C.

The shaft holes 5 to 5C are arranged along both side edges 12 and 13 of the claw 11 of the anchor 1 to be overlapped with the blade plate 2, and the pitch P between the shaft holes 5 and 5a on the tip side of the claw 11 is shaft hole 5b,
It is longer than the pitch P1 between 5C.

As shown in FIG. 4, the fastening fittings 3, 3a are formed into a U-shape by bending both ends of both threaded bolts 30 in the same direction at substantially right angles, and having threaded shafts 33, 33 on both sides of a presser rod 31.

Or, as shown in Figure 5, attach poles to both ends of the straight presser rod 31) 3
2. Insert 32 to form a U-shape.

The tightening fittings 3, 3a are attached to screw shafts 33, 33 and 33 at both ends.
The distance between the shafts a and 33a is the pitch PvP1 of each of the two sets of shaft holes 5, 5a and 5b, 5C opened in the blade plate 2.
matches.

Therefore, the shaft holes 5, 5a, 5b of the blade plates 2, 2.

Hold the blade plate 2 with the claw 11 so that the toe of the anchor 1 is located between 5C.
superimpose it on the front or back side of

Tightening metal fitting 3 is inserted from above the claw 11 where the blade plates 2 overlap.
, 3a, insert the threaded shafts at both ends of the metal fittings into the shaft holes of the vane plate 2, and screw the nuts 6 onto the protruding ends of each screw shaft to easily fix the vane plate 2 to the claws 11.

In the case of the fastening fitting 3 using ordinary bolts 32 as shown in FIG. 5, each shaft hole 5 to 5C of the blade plate may be threaded and the bolt 32 may be directly screwed into the fastening fitting 3.

The advantage of being able to attach the vane board 2 with screws as described above is that the vane board 2 and the anchor 1 can be loaded onto a ship in a separated state and transported to the dropping position, and the vane board 2 can be attached to the anchor 1 on the ship. It is possible to use it.

That is, the anchor 1 does not have the slats 2 attached until it is brought to the dropping position, and an anchor with less weight and bulk is easy to handle and load onto a ship. The slats will not damage the hull or get in the way when working on board.

Also, knowing that the width of the anchor claw 11 gradually increases toward the tip and the thickness becomes thinner, the threaded shafts 33, 33a at both ends of the fastening fitting 3.3a are attached to the side edges of the claw 11. Since the pitches P and P1 of the shaft holes 5, 5a, 5b, and 5C of the blade plate 2 are determined so that the shaft holes 5, 5a, 5b, and 5C of the blade plate 2 are in contact with each other, when a force is applied to the blade plate 2 in the extraction direction shown by the arrow 7 in FIG. , 3a screw shaft 33
．． 33.33a, 33a and the side edge of the claw 11 are engaged, and the blade plate 2 will not come off from the claw 11.

Also, in the direction of arrow 71 in FIG.
Even if a pushing force is applied to the proximal end of the claw 11, since the claw 11 gradually becomes thicker toward the proximal end, there is no risk of the blade plate 2 slipping toward the proximal end of the claw 11. The plate 2 is securely locked to the tip of the claw 11.

Even if the vane plate 2 is damaged, it can be easily replaced by removing the fastening fittings 3, 3a, and has many excellent practical effects.
