Description

[0001] ROPE PROTECTOR FOR SHIP [0002]

The present invention relates to a rope protector installed between a propeller and a rope guard.

The ship is provided with a rope guard between the stern propeller and the stern boss to prevent the rope from winding on the shaft seal of the propeller, and the rope guard is fixed to the stern boss.

The rope guards are spaced apart from the propellers in order to prevent the rotating propellers from being damaged by contact with the fixed rope guards. The spacing between the rope guard and the propeller can typically be about 10 mm.

However, since there is a possibility that ropes and other foreign matter may penetrate into the space generated between the rope guard and the propeller, a secondary safety device is provided by attaching a rope cutter or a protector. The rope cutter is a device for circumferentially attaching to the outer diameter of the rope guard, and a rope cutter of the propeller is installed along the outer circumferential surface of the propeller. However, even if a rope cutter is installed, there is still a space between the propeller and the rope cutter. In addition, the conventional protector is mounted on the end surface of the propeller with bolts or the like, but it is difficult to construct and the propeller and the rope can not be efficiently blocked.

1 and 2, a propeller 2 is installed at the stern of a ship via a propeller shaft 4. [ The propeller shaft 4 rotates in connection with the engine and transmits the power of the engine to the propeller 2. The stern is provided with a rope guard 10 fixed to a stern boss 3. The rope guard 10 is spaced apart from the boss 2a of the propeller 2 by a gap have.

2, the rope protector 30 according to the first embodiment is a device for preventing the intrusion of foreign matter between the propeller 2 and the rope guard 10, A protection ring 31 inserted into the fixing groove 312 and protruding toward the rope guard 10 and having a fixing groove 312 and a fixture 32 inserted in the fixing groove 312 and supporting the protection ring 31 ).

The mounting groove 21 is formed on the outer surface of the propeller 2 and is formed on the boss 2a and extends along the outer circumferential direction of the propeller 2. The protection ring 31 is formed in a circular ring shape, and may be integrally formed, or may have a structure in which a plurality of pieces are connected. The protection ring 31 may be made of a material having elasticity, such as a fluorine-contained rubber, a general rubber, or a flexible synthetic resin.

The protection ring 31 is inserted into the mounting groove and includes two protrusions 313 protruding toward the rope guard and a fixing groove 312 formed between the protrusions 313. The protrusions 313 are spaced apart from each other with the fixing grooves 312 interposed therebetween so that the tips of the protrusions 313 may be in contact with the rope guard 10 or spaced apart from the rope guard 10 by an interval of less than 1 mm .

On the side surface of the projection 313, an inclined surface 314 inclined with respect to the side surface of the protection ring 31 is formed. A plurality of friction grooves 315 are formed on the side surface of the protection ring 31 which abuts the side surface of the seating groove 21 to increase the frictional force with the seating groove 21. Accordingly, the protection ring 31 can be stably fixed to the seat groove 21.

The fixing groove 312 may be located at the center of the width of the protection ring 31 in the x-axis direction and is formed to extend in the outer circumferential direction of the protection ring 31. The fixing member 32 is formed in a ring shape extending in the outer circumferential direction of the protection ring 31 and is inserted into the fixing groove 312 to support the protection ring 31 so as not to be detached from the mounting groove 21. The fastener 32 may be made of metal and may be made of metal wire or spring having a circular cross section. Thus, the rope protector 30 according to the present embodiment can be fixed to the propeller 2 and rotate together with the propeller 2.

When the fastener 32 is inserted into the fixing groove 312 as in the first embodiment, the protection ring 31 can be stably positioned without being detached from the fixing groove 21. [ It is also possible to reliably prevent foreign matter from entering between the propeller 2 and the rope guard 10 when the protection ring 31 made of fluorine rubber abuts the rope guard 10 or is spaced apart at a small distance.
