Description

[Detailed description of the invention] The present invention relates to improvements in anchors.

The main feature of the 5TEVIN anchor is that the hinge in the hinge receiver, which is formed almost at the geometric center of the fluke surface area by the connecting plate on the inner edge of the double-handed fluke, swings in the groove between the two-handed fluke. The two-handed flug is attached to the side of the anchor shank so as to move, and the head plate that limits the swing angle of the shank is connected to the connecting plate, and the pointed tip is inserted from a considerable depth on the inner edge of the two-handed flug. The two-handed flute is extended and converged to form a double-handed flute, and a rear stabilizing frame is installed on the outer edge of the double-handed flute.

Traditional anchors, two-handed flugs, end with a flat tip at the front. On hard ground, the anchors described so far have a shank that continues to slide along the ground and does not sink in any further.

The present invention overcomes the aforementioned drawbacks of conventional types of anchors and
Further, each of the two-handed flugs has a pair of outwardly curved finger-shaped points, and a flange plate with a rising point is disposed thereon to form a front stabilizing frame.

This novel property aims to obtain an anchor that improves the cutting-driving action in hard ground due to the fact that it increases the stability of the anchor during driving-in.

Another aspect is that the hinge receiver and the rear stabilizing frame are widened rearward when viewed from the plan view, that is, their openings are larger at the rear, so that there is no possibility that the dirt that gets stuck in the frame will interfere with the operation of the stabilizing frame. Don't let it happen.

Furthermore, it is equipped with a pre-cutter suitable for cutting the shank.

Additionally, this new anchor is characterized by an opening for the anchor shackle at the rear end of the Flug, and by casting the anchor shackle and hinge pin integrally with the shank.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, the anchor 1 has a pair of fluke arms 2, 2, which are joined together at the rear hinge receiver 3.

The shank 4 is a pin 5 which is pivoted in the hinge receiver 3.
The pivot is attached to Frug 2. Hinge receiver 3
There are a pair of Fluke angle restriction frames 6 on the upper and lower sides of the shank 4 in front of the shank 4, which extend backwards, and the rearwardly widened opening between these two prevents the formation of clods when entering the ground. Do it like this. Further, since the rear stabilizing frames 7, 7 are arranged and spread rearward, it is possible to prevent clods from being formed and interfering with the operation of the stabilizing frames.

In particular, the front stabilizing frame is illustrated in FIG.

Each of the flugs 2 has a pair of outwardly curved points 8.8 for entering hard ground.

When entering, the vertical flugs 9,9 of the inner and also outer tips 8,8 serve to stabilize, these pointing inwardly from the outwardly flared tip. There is an opening 11 on the rear side of the hinge receiver 3 that connects the two flugs 2, and the anchor 2
Providing an anchor shank that can be used for connecting connections. The anchor shackle 12 and hinge pin 5 are cast integrally with the shank 4.

As particularly shown in FIG. 2, the anchor 1 is provided with a pre-cutter 13 so that the shank 4 can be easily recessed. In this figure, the anchor is on the bottom of the water. If the diagram is turned upside down, the shank 4 represented by the dotted line shows the anchor lying on the deck 14, and the dotted line 15 shows the dimensions equivalent to a 15-ton anchor. Represents the height of the person indicated by . When the anchor 1 lies on the deck 14, it is in a state where it does not sink in so as not to damage the deck.

Generally speaking, the main factors in anchor retention are penetration, strength, and stability. Recession is obtained by means of sharp Flug points and, as far as possible, by means of streamlined anchors.

Penetration is obtained by arranging the limiting frame 6 so that the Fflug angle is maximized. As shown in FIG. 1, the Fluke angle limiting frame is made up of a plurality of plates extending rearward, forming an opening extending rearward when viewed in a cross section parallel to the anchor bottom.

The anchor is designed in such a way that no obstructions can enter the hinge receiver 3 that firmly connects the two flugs 2 in the ground into which it is sunk.

The shank 4 can be inserted through the hinge receiver from the rear and the hinge pin 5 can be held by two small locks.

Conventional anchors used in this manner on the seabed have the disadvantage that the combination of two anchors makes the anchor unstable. Generally, pennant wire is tied to the flug. In the anchor of the invention, the shackle 12 is attached to the pivot type shank 4. This way the pulling force will be aligned with the main chain or wire and the anchor will be stable. Furthermore, this has a separate shackle for use after bathing.
1' There is no need to do so, which results in savings in manufacturing. The pivot pin 4 is also cast integrally into the soil of the shank 4.

In order to prevent the formation of soil clods, that is, the obstruction of passing earth and sand, the depth of the flug within the angle of the limit frame 7 should be reduced. c (5
Ru. 0) For anchors, this will always result in early destruction of the anchor due to clods.

This pivot type anchor prevents this.

As mentioned above, in reality, generally on hard ground, the shank of a pivot type anchor keeps sliding along the ground, and it seems that it does not sink in any further.The part of the flug on hard ground On the one hand, the shank will still be somewhat drawn on the ground, and on the other hand, the displaced sediment will become as large as possible.

It prevents the tip of the square 16 fruiter from fitting in, and the round and (
or) the sharp point also limits the width of the flug's posterior side and thus the C surface area. By providing two sets of fluke points 8, good one-step cutting and penetration on hard ground will be achieved.

Note that this provides stability during insertion. The point of the flug pointing outwards is suddenly pointed towards the flug along the ground.
This helps in cutting in when the anchor is pulled.

For bite and stability, a vertical plate is placed on the front tip of the flug, which directs the front side 10 outwards. The purpose is that when the anchor slides sideways, the front vertical plate sinks into the ground, thereby pulling itself normally towards the ground again.

On the other hand, these vertical plates have the property that when the recessed anchor is at an angle, the tip of the most deeply recessed flug is automatically pulled out by the vertical plate 9 with a greater royal force, and the anchor becomes stable. It is something.

Stabilizing stocks, prisms or plates are often used in anchors. The disadvantage of using a stock on hard ground is that it prevents it from penetrating. Ifle
l) A frame structure like an anchor has the disadvantage that it spreads parallel to the fluke and has poor stability. In this case, the frame is simply recessed into the original shape.

The combination of the wings of the in) anchor and the frame of the El (1 (el) anchor) is such that the spreading plate compresses the sediment within the frame, creating a wall of sediment along the entire width of the frame structure when it bites in. There are drawbacks.

Stabilizing prisms have the disadvantage that when they sink into hard ground, they create excessive resistance and cause the anchor to break sooner than necessary.

For good penetration, the two fluke plates are bent outwards at the rear of the sides and on the outside are provided with a vertical flare plate 16, which advantageously stabilizes the anchor.

A strong stabilizing effect is achieved by the bent spreader plate 17.

In this case, it should be placed above and below the two flugs, spanning approximately one-third of the width of the flukes, and therefore a flipper (Fli
It is not full width like a pper anchor, nor is it parallel like a reel anchor.

This stability frame has a simple structure, and the top part 18 is set in the correct position (((), and the sides are in the correct stable state. Moreover, this anchor can easily pass through without dirt accumulating due to the spread shape of this stability frame. , continue the correct sinking motion.

The fluke angle limiting frame 6 with claws 6' for digging into hard ground and the stabilizing frame are designed so that the anchor points upward with the fluke point, so that when handling the anchor, the deck of the ship does not have a sharp point 6' or 10. Therefore, the anchor is constructed so that it cannot be damaged by
・The anchor will automatically set to 3 points 20 when pulled into the wire.
Stop at . When pulling the anchor forward to re-enter the water, a removable wire or rod 21 can be clamped between the fluke and the shank for an hour as shown.

At the bottom of the sea, the Flug automatically tilts its tip downwards due to the high pressure on the restriction frame. On soft seabeds, the upper and lower surfaces of the stabilizing frame will adjust the sinking angle.

As already mentioned above, on hard ground the shank tends to slide on its bottom. Pre-cutter 13 as shown
When using a shank, a groove is first cut in the hard ground, making it convenient for the shank to sink into.

Figures 9 through 11 show rack guides 22 for properly racking the anchor. It is quite true that the corners of the shank pose an obstacle when pulling the anchor into the rack. This is because when the anchor is pulled into the rack, the corners of the shank cause the anchor to be tilted and the bolster or rack to be wedged between the two flugs. A pyramidal boss on the forward side of the shank, shown in cross-section in FIG. 11, allows the anchor to be turned in the correct direction and positioned correctly under the rack.
