Description

  The present invention relates to a mooring rope joint for connecting mooring ropes used for mooring in the sea or the like.

  For example, a mooring rope is used to moor a floating body such as a buoy on the sea to a sink such as an anchor submerged in the sea floor.

  As such a mooring rope, there exists what connected the mooring rope extended from the floating body side and the mooring rope extended from the sedimentation object side like patent document 1. FIG. For the connection between the mooring ropes, a metal shackle such as stainless steel is used as a joint.

  However, the mooring rope is generally made of a resin such as polypropylene or polyamide having a small specific gravity and being easy to float on water from the viewpoint of reducing the buoyancy of the floating body.

  For this reason, the metal shackle, which is a joint, has a specific gravity several times that of the mooring rope, and there is a problem that a joint part that is greatly submerged in the vertical direction is formed between the mooring ropes connected. .

  On the other hand, it is conceivable that the shackle is simply made of resin, but there is a problem of insufficient strength.

JP 2014-117980 A

  The problem to be solved is that the joint for the mooring rope connecting the mooring ropes forms a joint part that sinks greatly during the mooring if sufficient strength is secured.

  The present invention is a mooring rope joint for connecting a pair of mooring ropes in order to suppress the formation of a joint part that is greatly depressed during mooring while ensuring sufficient strength. A main body portion formed of a material having a specific gravity equivalent to that of the mooring rope, and the end portions of the pair of mooring ropes are held in a chain-like manner along the main body portion. The main feature is that the first guide path and the second guide path are provided.

  The mooring rope joint according to the present invention maintains a state in which a ring-shaped end portion of a pair of mooring ropes is connected to a main body portion having a specific gravity equivalent to that of the mooring rope, so that sufficient strength is ensured. However, it is possible to suppress the formation of a joint part that has greatly sunk during mooring.

  The mooring rope joint 1 according to the present embodiment includes a main body 5 and first and second guide paths 7 and 9.

  The main body 5 is formed of a material having a specific gravity equivalent to that of the pair of mooring ropes 3a and 3b. The main body portion 5 of the present embodiment is made of a material having a specific gravity of 1 or less. As such a material, for example, a resin such as ultrahigh molecular weight polyethylene can be used.

  The specific gravity of the main body 5 is preferably the same as the specific gravity of the mooring ropes 3a and 3b, but may be the same as that set within a certain allowable width with respect to the specific gravity of the mooring ropes 3a and 3b. The allowable width of the specific gravity is preferably about 5% of the specific gravity of the mooring ropes 3a and 3b.

  In the present embodiment, it is preferable that the specific gravity is equal to one of the specific gravities, or the specific gravity between the specific gravities, because the mooring ropes 3a and 3b of different materials are connected. However, it may be made larger than the mooring rope 3b (polyamide specific gravity 1.14) having a relatively large specific gravity or smaller than the mooring rope 3a (polypropylene specific gravity 0.91) having a relatively small specific gravity. Is possible.

  The main body 5 has a spherical shape as a whole. The main body 5 of the present embodiment is formed in an oval shape. However, it is not a perfect oval shape but has a flat end. However, the main body 5 may be a simple sphere, or may be a cube or other three-dimensional shape. A circular recess 11 is formed on the outer periphery of the main body 5 along the long spherical short axis Y.

  The first and second guide paths 7 and 9 are connected to the main body 5 along the annular ends 3aa and 3ba of the pair of mooring ropes 3a and 3b, and the ends 3aa and 3ba are connected in a chain. It is for holding in a state. These first and second guide paths 7 and 9 are provided with hole portions 7a and 9a and groove portions 7b and 9b.

  The holes 7a and 9a of the first and second guide paths 7 and 9 are located on both sides in the direction along the long axis X with respect to the oval center O, respectively. These holes 7a, 9a are provided through the main body 5 through the major axis X in the direction along the minor axis Y. However, the holes 7a and 9a do not extend in the same direction, but intersect each other in front view or rear view.

  A direction along the minor axis Y passing through the major axis X is referred to as a “radial direction”, and a direction along the major axis X is referred to as a “longitudinal direction”. The end portions 3aa and 3ba of the mooring ropes 3a and 3b are inserted into the hole portions 7a and 9a, respectively.

  The distances D1 and D2 in the longitudinal direction between the center O1 of the holes 7a and 9a and the center O of the main body are the same. However, the distances D1 and D2 may be different, but are preferably the same in consideration of balance.

  The groove portions 7b and 9b are provided along the outer periphery of the main body portion 5 from both ends of the hole portions 7a and 9a. In the groove portions 7b and 9b, end portions 3aa and 3ba of mooring ropes 3a and 3b inserted through the hole portions 7a and 9a respectively hang.

  The groove portion 7b of the first guide path 7 extends from the hole portion 7a of the first guide path 7 to the end portion of the main body portion 5 that is relatively far from the hole portion 7a, beyond the center O of the main body portion 5. It is provided along the direction. The end portions of the groove portions 7 b on both sides of the hole portion 7 a are opposed to each other in the radial direction via the discontinuous portion 13 at the end portion of the main body portion 5.

  Similarly, the groove 9b of the second guide path 9 extends from the hole 9a of the second guide path 9 over the center O of the main body 5 to the end of the main body 5 that is relatively far from the hole 9a. It is provided along the longitudinal direction. The end portions of the groove portions 9 b on both sides of the hole portion 9 a are opposed to each other in the radial direction via the discontinuous portion 15 at the end portion of the main body portion 5.

  The depths of the grooves 7b and 9b are greater than the wire diameter d of the ends 3aa and 3ba of the mooring ropes 3a and 3b, and the ends 3aa and 3ba of the mooring ropes 3a and 3b are the outer circumferences of the main body 5. It is designed not to protrude from. The inner surfaces of the groove portions 7b and 9b are arcuate surfaces according to the end portions 3aa and 3ba of the mooring ropes 3a and 3b.

[Operation of mooring rope joints]
When the mooring rope joint 1 of the present embodiment is used, the anchor rope 3a extending from the floating body side such as a buoy and the end of the mooring rope 3b extending from the sinking object side in advance before sinking a sinking object such as an anchor to the seabed or the like. The portions 3aa and 3ba are connected by the mooring rope joint 1.

  When the sinking object is set on the seabed or the like, the floating body can be moored to the sinking object via the mooring rope 3b, the mooring rope joint 1, and the mooring rope 3a.

  At this time, the mooring rope joint 1 has a spherical main body 5 formed of a material having a specific gravity equivalent to that of the pair of mooring ropes 3a and 3b, and annular end portions 3aa and 3ba of the pair of mooring ropes 3a and 3b. Since the first guide path 7 and the second guide path 9 that maintain the chain-connected state are provided, the joint portion that is greatly sunk between the mooring ropes 3a and 3b is not formed.

  In addition, since the mooring rope joint 1 is interposed between the annular ends 3aa and 3ba of the mooring ropes 3a and 3b in the direction in which the main body 5 of the sphere is compressed, sufficient strength can be secured.

  Further, the mooring rope joint 1 has a main body portion 5 having an oblong shape, so that the underwater resistance can be suppressed in combination with the specific gravity being 1 or less.

[Effect of Example 1]
As described above, the mooring rope joint 1 according to the present embodiment includes the main body 5 formed of a material having a specific gravity equivalent to that of the pair of mooring ropes 3 a and 3 b, and the pair of moorings with respect to the main body 5. A first guide path 7 and a second guide path 9 are provided along the annular ends 3aa, 3ba of the ropes 3a, 3b and holding the ends 3aa, 3ba connected in a chain.

  Therefore, in this embodiment, the main body portion 5 having a specific gravity equivalent to that of the mooring ropes 3a and 3b is held in a chained state along the annular ends 3aa and 3ba of the pair of mooring ropes 3a and 3b. Therefore, it is possible to suppress the formation of the joint portion that has greatly sunk during anchoring while ensuring sufficient strength.

  In this embodiment, since the specific gravity of the main body 5 is 1 or less and floats on water, it is possible to reliably suppress the formation of joint portions between the mooring ropes 3a and 3b having the same specific gravity.

  And since the main-body part 5 is oblong, it can suppress underwater resistance. Moreover, coupled with the long sphere shape and the specific gravity being 1 or less, the underwater resistance can be more reliably suppressed.

  The first guide path 7 and the second guide path 9 include holes 7a and 9a that penetrate the main body 5 and grooves 7b that are provided along the outer periphery of the main body 5 from both ends of the holes 7a and 9a. , 9b.

  For this reason, in the present embodiment, the pair of mooring ropes 3a and 3b are surely placed along the annular ends 3aa and 3ba with respect to the main body 5 and the ends 3aa and 3ba are connected in a chain. Can be held.

  Further, the mooring rope joint 1 can prevent the end portions 3aa and 3ba of the mooring ropes 3a and 3b from coming off by the holes 7a and 9a, thereby realizing a reliable connection of the end portions 3aa and 3ba of the mooring ropes 3a and 3b. .

  Further, the holes 7 a and 9 a of the first guide path 7 and the second guide path 9 are located on both sides in the direction along the long spherical long axis X with respect to the center of the main body 5, and the first guide path 7. And the groove parts 7b and 9b of the 2nd guide path 9 are extended along the long axis X from the both ends of the hole parts 7a and 9a over the center O of the main-body part 5, respectively.

  Accordingly, in the mooring rope joint 1 of the present embodiment, the spherical body 5 is interposed in the direction of compression between the annular ends 3aa and 3ba of the mooring ropes 3a and 3b, but the length of the intervening portion is ensured. The strength can be ensured more reliably.

  Moreover, since the groove parts 7b and 9b of the 1st guide path 7 and the 2nd guide path 9 have the depth more than the wire diameter d of the mooring ropes 3a and 3b, the protrusion of the mooring ropes 3a and 3b is suppressed, and underwater resistance is reduced. It can suppress more reliably.

[Others]
In the mooring rope joint 1, the first and second guide paths 7, 9 may be configured by the groove portions 7 b, 9 b with the holes 7 a, 9 a being omitted from the first embodiment.

  In this case, the groove portion 7 b of the first guide path 7 is provided in a circular shape on the outer peripheral surface of the main body portion 5, and the groove portion 9 b of the second guide path 9 intersects with the groove portion 7 b of the first guide path 7. 5 may be provided on the outer peripheral surface in a circular shape.

  Thus, even if it is the structure which provided the groove parts 7b and 9b in the periphery shape, there can exist an effect similar to Example 1. FIG. Note that if the end portions 3aa, 3ba of the mooring ropes 3a, 3b are tightly ring-shaped along the groove portions 7b, 9b, they can be prevented from coming off.
