Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a mooring chain attachment structure for a floating body.

[Conventional technology]

For example, as shown in the 10th front view, as a mooring chain attachment structure for a floating wave levee, conventionally, as shown in the 10th front view, mooring chains are installed at appropriate intervals on the lower part of both side plates 02 of a flat upright cubic floating body 01, respectively, protruding outward. Ta? Soyasokuru 0 for each eye plate 03 of 3I number
It is known to connect the upper ends of the mooring chains 05 via 4.

Here, 06 is the bottom plate of the floating body 01.

However, such a structure has the following drawbacks.

1) Since the attachment position of the mooring tJf05 to the Nyanokuru 04 is limited to the upper end of the mooring chain 05, it is impossible to adjust the length of the mooring chain 05, so there is no flexibility in the attachment work, and the installation cost increases. Furthermore, if the length of the mooring chain 05 is too long, the excess length must be cut and removed, which is therefore uneconomical.

(2) Since the eye plate 03 is protruded from the side of the floating body 01 + the lower part of the floating body 02, the connection with the mooring chain 05 via the shackle 04 must be performed at sea, and therefore the installation work is not easy. Furthermore, it is difficult to bring a work boat alongside the floating body 01, and therefore, the installation work is difficult.

(3) The connecting parts of the eye plate 03 and the shank 04 do not have a smooth shape, so there is a lot of rubbing due to uneven contact, and therefore, there is significant wear, and the mooring chain caused by waves due to the large friction. 05 cannot be undone.

[Problem to be solved by the invention]

The present invention was proposed in view of these circumstances, and
The length of the mooring chain can be adjusted, and installation work is easy.
Additionally, the attachments and mooring chains are subject to wear and tear, thus reducing flexibility.
The purpose of the present invention is to provide a mooring chain attachment structure for a floating body with excellent workability and maintainability.

[Means to solve the problem]

To this end, the present invention provides a cylindrical housing attached to the lower corner of the floating body with an appropriate length and an upward slope toward the inside;
It is formed by combining a housing partial spherical concave surface formed on the inner surface of the lower end of the housing and a pair of front and rear S7 bars, and has a partial spherical concave surface in contact with the chain ring on the upper surface, and the housing partial spherical concave surface on the lower surface. The present invention is characterized by comprising a stopper having a partially spherical convex surface in contact with the mooring chain and having a chain ring clamping hole in the center thereof, and means for coupling the stopper pieces to the mooring chain in a manner that allows the stopper pieces to be removably inserted into each other.

[Effect]

With the above-mentioned configuration, the length of the mooring chain can be adjusted, the installation work is easy, and the attachment tool and the mooring chain are less likely to wear out.
Therefore, it is possible to obtain a mooring chain attachment structure for a floating body that has excellent flexibility, workability, and maintainability.

〔Example〕

An embodiment in which the present invention is applied to a floating wave levee will be explained with reference to the drawings. The same reference numerals as in FIG. 10 indicate the same members as in the same figure, respectively. In the partially enlarged view, l is a cylindrical housing that is attached to the joint between the side plate 02 and the bottom plate 06 of the floating body O1 and extends inward for a suitable length with an upward slope, and the thickness of the housing gradually increases downward. , the lower end is a stopper receiver 3 having a partially spherical concave surface 2.

Next, in the third front view, the side view in FIG. 4, and the horizontal cross-sectional view in FIGS. A stopper with a partially spherical surface, which has a partially spherical concave surface 6 with a relatively small diameter r in contact with a pair of left and right stopper pieces 7.
It is composed of a combination of a plurality of horizontal bolt holes 8 drilled on both sides of the stopper piece 7, a mooring chain holding groove 9 formed at the bottom of the stopper piece 7, a bolt 10 and a bolt 11, etc. There is.

In such a structure, in order to attach the mooring chain 05 to the floating body 01, as shown in FIG.
The upper end of the mooring chain 05 is pulled into the floating body 01 and positioned, and then the stopper pieces 7 are brought into contact and sandwiched between the front and rear of the positioning part of the mooring chain 05, as shown in the seventh factor view. , tighten through multiple bolts 10, etc., and attach the stopper 4, and then attach it to the housing 1.
Set inside.

In such a situation, the action of the waves causes the
As shown in the partial cross-sectional view of the figure, even if the mooring tji05 is forcibly bent or twisted, the stopper 4 slides on the partially spherical concave surface 2 formed on the stopper receiver 3 of the housing 1, and the universal joint is secured. Therefore, the ninth
As shown in the partial cross-sectional view of the figure, the mooring chain 05 will not be forced to bend or twist.

According to such a structure, the following effects can be achieved.

(1) A cylindrical housing is provided at the bottom of the outer shell of the floating body with an appropriate length and an upward slope toward the inside.The upper end of the mooring chain is pulled into the floating body from the water through the housing, and the installation work is carried out inside the floating body. At the same time, it becomes possible to
It becomes easier to come alongside the work force, and work efficiency is therefore improved.

(2) Since the stopper receiver having a spherical concave surface is provided on the lower end of the inner surface of the housing, the stopper receiver comes into contact with the stopper like a universal joint, thus reducing wear and tear. At the same time, the mooring chain is free from unreasonable bends and twists, which improves the integrity of the structure.

(3) A stopper that is formed by combining a pair of front and rear stopper pieces and has a partially spherical concave surface in contact with the chain ring on the upper surface, a partially spherical convex surface in contact with the housing part spherical concave surface on the lower surface, and a hole for holding the chain ring in the center part. The provision of this reduces wear and tear on the mooring chain, nozzle and stopper, thus increasing the integrity of the structure.

(4) Since bolts, nuts, etc. are provided for connecting the stopper pieces to the mooring chain in a manner that allows them to be fitted and removed from each other, the length of the mooring chain can be adjusted, thereby improving flexibility in use.

〔Effect of the invention〕

In short, according to the present invention, there is provided a cylindrical housing attached to a lower corner of a floating body with an appropriate length and an upward slope toward the inside, a partially spherical concave surface of the housing formed on the inner surface of the lower end of the housing, and a pair of front and rear cylindrical housings. A stopper formed by combining stopper pieces, having a partially spherical concave surface in contact with the chain ring on the upper surface, a partially spherical convex surface in contact with the housing partially spherical concave surface on the lower surface, and having a hole for holding the chain ring in the center part. , and a means for connecting each of the stopper pieces to the mooring chain in a removable manner allows the length of the mooring chain to be adjusted, the installation work is easy, and the attachment and the mooring chain are free from wear and tear. Therefore, the present invention is extremely useful industrially because it provides a mooring chain attachment structure for a floating body that has excellent flexibility, workability, and maintainability.
