Description

Functional rope assembly {FUNCTIONAL ROPE ASSEMBLY}

The present invention relates to a functional rope assembly for connecting to an anchor or the like so that a floating structure does not drift at sea or on water.

In general, structures on the sea or water are connected to anchors and ropes at the bottom of the water to prevent drifting.

At this time, the rope is always provided with a sufficient length considering the difference between the tides at sea or the water level according to the amount of rainfall. Since there is a possibility of occurrence of problems such as kinking between the ropes, it has been proposed to restrict the flow by attaching weights at regular intervals along the length of the rope.

However, since the management of the rope becomes difficult as well as there is a risk of corrosion, recently, a rope made of a rubber material has been proposed. However, the rubber rope has the advantage of connecting the water structure and the anchor in a taut state due to its elasticity in the longitudinal direction. there was

In consideration of this problem, recently, in Patent Registration No. 10-1180721 (September 10, 2012) and Patent Registration No. 10-1504023 (March 18, 2015), as shown in FIG. 1, the external support material (1) of the rope ) and a method of reinforcing the strength by inserting a fiber reinforcement (3) between the internal support material (2) has been proposed.

However, there is a risk that seawater or the like flows between the outer support material 1 and the inner support material 2 to corrode the fiber reinforcement material 3 . Moreover, in a structure in which the fiber reinforcement 3 is simply inserted, when a tensile force is applied to the rope, it is a very difficult problem in reality to have a binding structure in which the three components receive tensile force at the same time and share the load. couldn't

On the other hand, in relation to the binding structure of the rope, in Patent Registration No. 10-2255851 (May 25, 2021. 5.), as shown in FIG. 2, the fixed connection parts 22 and the body part 21 at both ends of the rope 10 are used. Although the connecting rope binding portion 20 has been proposed, when a strong tensile force is applied, there is a problem in that the rope 10 is pulled out from the fixed connection portion 22, so an improvement is required.

Accordingly, an object of the present invention is to provide a functional rope assembly that can be stretched according to tensile force, but includes a functional elastic mooring rope that does not cause corrosion of reinforcing fibers, and can prevent the rope from falling out by having a strong binding structure. there is

In order to achieve the above object, in the present invention, in a functional elastic mooring rope, a compressed rubber to be extruded, a braided fiber surrounding the outer circumferential surface of the compressed rubber, and a compressed rubber wrapped with the braided fiber are passed through an extruder to produce the braided fiber. a rubber rope made of elastic rubber which is attached to the outer circumferential surface of the compressed rubber with a predetermined thickness and integrated therein; a metal reinforcing pin penetrating both ends of the rubber rope in the axial direction; It is a metal pipe fitted to the outer peripheral surface of both ends in the axial direction of the rubber rope, and by compression molding with a hydraulic press, the rubber rope is compressed and pressed in the radial direction toward the reinforcing pin at the center and at the same time includes a compression socket integrally coupled with them. It provides a functional elastic mooring rope, characterized in that.

Here, the functional elastic mooring rope further includes a stainless woven tube surrounding the outer circumferential surface of the rubber rope, and the compression socket includes the metal pipe being inserted into the outer circumferential surface of the woven tube while the woven pipe wraps the rubber rope. By compression molding with a hydraulic press, it may be configured to be integrally coupled with the rubber rope.

In addition, the compression socket may be compression-molded by the press so that the major axis and the minor axis are alternately formed along the axial direction.

On the other hand, the functional elastic mooring rope may further include a fastening flange welded to the axial end of the compression socket.

Alternatively, instead of the flange, the functional elastic mooring rope may further include a fastening bolt having a head portion welded to the axial end of the compression socket and a shank portion protruding from the head portion in the axial direction.

And, in order to achieve the above object, the present invention relates to a functional rope assembly including the functional elastic mooring rope, wherein the flanges are fastened to two or more fastening portions axially symmetrically disposed on one side of the plate surface, so that the two or more functional elastics are fastened. Connected to the mooring rope, it provides a functional rope assembly, characterized in that it further comprises an integrated plate provided with an eye bolt or hook on the other side plate surface.

Here, in the fastening part, the flange is laminated on the plate surface of the integrated plate, and the functional rope assembly is laminated on the plate surface of the integrated plate in the fastening part, the inner peripheral surface supporting the outer peripheral surface of the flange in surface contact and the a holder flange having a plurality of bolt accommodating grooves that are axially symmetric along the inner circumferential surface and are recessed in the radial direction; It may further include a cover flange bolted to the integrated plate through the plurality of bolt accommodating grooves in a state in which the flange is supported by surface contact in the axial direction, but stacked on the holder flange.

In addition, in order to achieve the above object, in the functional rope assembly including the functional elastic mooring rope, the shank part is inserted and fastened into two or more fastening holes formed axially symmetrically on one side of the plate surface to achieve the above object. It provides a functional rope assembly, which is connected to the functional elastic mooring rope, and further comprises an integrated plate provided with an eye bolt or a hook on the other side of the plate.

As described above, according to the functional rope assembly according to the present invention, in the middle of the secondary extrusion molding process of the rubber rope, the braided fibers are wrapped in the inner compressed rubber and passed through the extruder to attach the outer elastic rubber to integrally molding. Since the braided fibers can have a structure in which they are integrated in the state of being embedded in the elastic rubber, it is possible to completely block the inflow of seawater between the elastic rubbers of the compressed rubber through this, thereby preventing corrosion of the braided fibers. have.

In addition, a compression socket obtained by inserting a metal pipe on the outer circumferential surface in a state in which a metal reinforcing pin is penetrated into the axial end of the rubber rope and compression molding it with a hydraulic press is configured as a binding medium of the rubber rope. Even when a strong tensile force is applied to the rope, it is possible to prevent a phenomenon from falling out of the compression socket.
