JPH074288U - Horizontal mooring anchor - Google Patents

Abstract

(57) [Summary] [Purpose] An anchor for horizontal mooring that has a main anchor part and an auxiliary anchor part can secure a lateral mooring state, and provides an anchor that exerts a great mooring force in mooring sand. thing. A mooring chain 4 engages with a main anchor portion 1 at or near the center thereof, while a mooring chain 25 is attached to an auxiliary anchor portion 2 and a distal end portion of an arm distant from the center through a swing link 25. The pulling force from the mooring chain 4 which accompanies the movement of the ship causes the swing link 2 to engage.
A large component force is exerted in the main anchor portion direction via 5 to act on the main anchor portion and the auxiliary anchor portion 2 at the same time, and due to the component force in the main anchor portion direction, a normal mooring of the anchor of the mooring chain is performed. Even at an angle or more, the mooring action in the substantially horizontal direction from the main anchor portion to the auxiliary anchor portion along the shank member is exhibited.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a horizontal mooring anchor which is excellent in mooring sand.

[0002]

[Prior art]

 As shown in Fig. 4, for mooring sandy ground, a T-shaped stock T is formed at the tip of the shank S standing upright from the hook claw F so that the anchor is laid horizontally on the seabed. When the mooring chain C is fixed to T and the stock T stops at the bottom of the sea (see Fig. 4 (a)), the hook claw F sticks into the bottom of the sea and the shank S falls horizontally (Fig. 4). (See (b)).

[0003]

[Problems to be solved by the device]

 However, when tension is applied to the mooring chain C, the stock T rises up and the mooring force is affected by the hooking of the hook claw F with the sea bottom. There is a problem that you can not do. In order to solve the above problems, the inventor has focused on increasing the mooring force by installing auxiliary anchors instead of the stock T. However, the other end of the shank member is similar to the conventional one. It was found that when the mooring chain is directly attached to the mooring chain C, when a tensile force is applied to the mooring chain C, the auxiliary anchor part rises up and the horizontal installation state cannot be secured. An object of the present invention is to provide a structure capable of ensuring a horizontal mooring state in a horizontal mooring anchor having a main anchor portion and an auxiliary anchor portion provided side by side via a shank member.

[0004]

[Means for Solving the Problems]

 In the present invention, the engagement relationship of the mooring chains with respect to the main anchor portion and the auxiliary anchor portion is important in order to place the main anchor portion and the auxiliary anchor portion juxtaposed on both ends of the shank member in the laterally placed state as much as possible. The main anchor portion 1 having a plurality of arms 11 radially extending from one end of the shank member 3 to the periphery thereof, and the main anchor portion 1 radially extending from the other end of the shank member 3 to the periphery thereof. An auxiliary anchor portion 2 having a plurality of arms 21 shorter than the arm 11 of the main anchor portion, and further a mooring chain 4 engages at or near its center in the main anchor portion 1 and then along the shank member 3. The auxiliary anchor portion 2 and the distal end portion of the arm 23 distant from the center of the auxiliary anchor portion 2 through the swing link 25 to engage with the main anchor portion 1 and the auxiliary anchor portion 2. And it is characterized in that it kicked Installing to pulling the anchor section 2 at the same time.

[0005]

[Action and effect of the device]

 According to the present invention, the mooring chain 4 is engaged with the main anchor portion 1 at or near the center thereof, while the swing link is attached to the auxiliary anchor portion 2 and the tip of the arm that is spaced outward from the center. 25, the pulling force from the mooring chain 4 accompanying the movement of the ship is largely divided in the direction of the main anchor portion via the swing link 25, and the main anchor portion and the auxiliary anchor portion 2 are simultaneously subjected to the pulling force. In addition to acting, the component force in the direction of the main anchor described above assists along the shank member from the main anchor even at 45 to 60 ° above the normal mooring angle (about 30 °) with respect to the anchor of the mooring chain. As a result of exerting a mooring effect in a substantially horizontal direction up to the anchor part, lateral mooring is secured and the mooring effect on sand is significantly increased. On the other hand, when the mooring chain 4 is pulled up in the vertical direction, the main anchor portion 1 is pulled up after the auxiliary anchor portion 2 is raised, so that there is no hindrance to the pulling work. Since the anchor composed of the main anchor portion and the auxiliary anchor portion is bulky during transportation and storage, it is possible to separate the main anchor portion 1 and the auxiliary anchor portion 2 provided side by side via the bar member 3. Is preferred.

【Example】

 FIG. 1 is an exploded perspective view of an anchor for horizontal mooring according to the present invention, in which a main anchor portion 1 and an auxiliary anchor portion 2 are provided side by side via a shank member 3.

In the drawing, the main anchor portion 1 has four arms 11 each having a length L1 and extending in four directions at an angle of 90 degrees at the tip of the shank member 3 and having the tip bent upward by about 45 degrees. Then, a pentagonal claw blade 12 is attached to the tip end portion of the shank member 3 while being inclined slightly inward from substantially vertical. On the other hand, the auxiliary anchor portion 2 has an arm 21 having a length L2 shorter than that of the arm of the main anchor portion, which extends in all directions at the rear end portion of the shank member 3 and also forms an angle of 90 degrees, and its tip portion Claw blades 22 are attached to the shank member 3 in the vertical direction except one.

The shank member 3 is separated in the vicinity of the main anchor portion 1, and the short side portion 31 and the long side portion 32 are fitted and assembled together, and can be fixed with a screw 33.

The mooring chain 4 has one end attached to the short side portion 31 of the shank member 3 in the main anchor portion 1 and extends along the long side portion 32 of the shank member 3 in the auxiliary anchor portion 2. The outer end of the stock 21 to which the claw blade 22 is not attached is engaged with the tip of a fitting member 23, which is retained by a pin 24, via a swing link 25, and is pulled upward.

Therefore, when the above anchor is thrown into the sea, when the main anchor part 1 stops at the sea bottom, it falls horizontally and becomes horizontal as shown in FIG. 2, and not only the claw blade 12 of the main anchor part 1 but also The claw blade 22 of the auxiliary anchor part 2 will also bite into the seabed. The pulling force from the mooring chain 4 accompanying the movement of the ship is largely divided in the direction of the main anchor portion via the swing link 25, and not only acts on the main anchor portion 1 and the auxiliary anchor portion 2 at the same time, but also the main anchor portion. Even if the mooring angle of the mooring chain 4 with respect to the anchor is 45 ° to 60 °, the mooring force in the direction of the arrow from the main anchor part 1 to the auxiliary anchor part 2 along the shank member 3 is exerted, and the component force in the direction of the sea bottom Even if it is sandy land, a great mooring effect is exhibited.

On the other hand, unfortunately, as shown in FIG. 3 (a), if the claw blade 12 of the main anchor portion 1 bites into the reef R and is moored, the mooring chain 4 moves in the direction of arrow A at the time of pulling up. Because of the pulling, the pin engagement of the fitting member 23 is released and the mooring chain 4 is disengaged from the auxiliary anchor portion 2 (see FIG. 3 (b)). The detached mooring chain 4 reaches the main anchor portion 1 side and is pulled in the direction of arrow B (see FIG. 3 (c)), so that the claw blade 22 biting into the reef R is pulled in the direction opposite to the biting direction. In some cases, it is pulled up (see FIG. 3 (d)).

Although the mooring chain 4 is used in the above-described embodiment, a mooring rope may be used, and it is easily deformed without departing from the scope of the present invention.
