Description

Technical Field

[0001] The utility model relates to the technical field of ships and marine engineering, in particular to a buffer structure of a ship fairlead sheath. Background Art

[0002] When the ship is moored at the port, the polymer cable is connected to the mooring machine and the cable bollard of the dock through the cable guide holes on the bulwarks on both sides of the bow and stern to fix the ship to prevent the ship from moving due to waves. The tension of the cable is generally between 30t and 125t. In order to prevent the polymer cable from breaking and endangering the operators, causing casualties and safety accidents, the most common method on the market is to wrap the cable with polymer woven cloth (cable sheath).

[0003] The cable sheath needs to be installed in the cable guide hole when in use. During the pulling process of the cable, the cable will squeeze the cable sheath. Since the existing cable sheath lacks a buffer structure, when the cable continues to squeeze the cable sheath, it will cause damage to the cable and the cable guide hole, affecting the service life.

[0028] Embodiment 2:

[0029] like Figure 1-8As shown, the buffer structure of the ship fairlead sheath according to the embodiment of the utility model includes a sheath 1 and a sheath 2, wherein the sheath 1 is connected to the sheath 2 by bolts 3, and the outer walls of the sheath 1 and the sheath 2 are both provided with a plurality of evenly distributed arc-shaped buffer frames 4, and the concave surface of the arc-shaped buffer frame 4 is provided with a mounting groove 1 5, and the mounting groove 1 5 is provided with a buffer airbag 6, and the concave surface of the arc-shaped buffer frame 4 is provided with a reset component matching the buffer airbag 6. The sheath 1 and the sheath 2 2 are both made of polymer resin rubber material. A plurality of evenly distributed positioning blocks 7 are provided on one side of the sheath 1, and a positioning groove 8 matching the positioning block 7 is provided on one side of the sheath 2. The reset assembly includes a symmetrically arranged installation groove 2 9 provided on the concave surface of the arc-shaped buffer frame 4, a reset airbag 10 is provided in the installation groove 2 9, the reset airbag 10 is connected to the buffer airbag 6 through a connecting pipe 11, a plurality of uniformly distributed elastic bands 12 are provided in the reset airbag 10, and both ends of the elastic bands 12 are connected to the inner wall of the reset airbag 10. A through groove matching the connecting pipe 11 is provided in the arc-shaped buffer frame 4.

[0030] In actual application, the sheath 1 and the sheath 2 are respectively inserted into the docking from both sides of the cable guide hole, and then the bolts 3 are tightened to fix the sheath 1 and the sheath 2 together. When the cable squeezes the inner walls of the sheath 1 and the sheath 2, the sheath 1 and the sheath 2 begin to squeeze the inner wall of the cable guide hole through the buffer airbag 6. At this time, the buffer airbag 6 is squeezed to introduce the internal gas into the reset airbag 10 through the connecting pipe 11. The buffer airbag 6 is compressed to achieve a buffering effect, and the inner wall of the reset airbag 10 begins to expand. At this time, the elastic band 12 is in a stretched state. When the cable squeezes the sheath When the squeezing force of the inner wall of the sheath 1 and the sheath 2 becomes smaller, the elastic band 12 starts to reset and drives the reset airbag 10 to contract. The reset airbag 10 contracts and reintroduces the internal gas into the buffer airbag 6 through the connecting tube 11, so as to facilitate its next use. By arranging an arc-shaped buffer frame and a buffer airbag, when the cable squeezes the sheath, the sheath squeezes the cable guide hole through the buffer airbag, which has a buffering effect and prevents the cable and the cable guide hole from being squeezed and damaged. At the same time, a reset component is provided to inflate the inside of the buffer airbag when the squeezing force of the cable becomes smaller, so that the airbag re-expands, thereby further improving the practicality of the sheath.

[0031] In summary, with the aid of the above-mentioned technical scheme of the utility model, by arranging an arc-shaped buffer frame and a buffer airbag, when the cable squeezes the sheath, the sheath squeezes the cable guide hole through the buffer airbag, thereby achieving a buffering effect and preventing the cable and the cable guide hole from being squeezed and damaged. At the same time, a reset component is provided, which will inflate the inside of the buffer airbag when the squeezing force of the cable becomes smaller, causing the airbag to re-expand, further improving the practicality of the sheath.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
