The attachment part (root stop) is shown.

The take-up reel 8 for the towline 13 is installed in the reel storage portion 25 on the lower deck 2 in the non-exposed compartment 24 of the ship as described above, and usually comprises the rope 16, socket 15 and stopper 14. (Details will be described later), the towline 13 and the like are wound around the reel 8. The stopper 14 may be taken out of the reel 8 and only the rope 16 may be wound around the reel 8.

The stopper 14 is formed in a disk body having a diameter larger than that of the rope pipe 7, that is, even if the towline 13 deviates to one side in the rope pipe 7, the stopper 14 is a stopper.
A size such that 14 can be engaged with the opening edge of the rope pipe 7 without fail, for example, about 2 times the diameter of the opening edge of the rope pipe 7.
Insertion hole formed in the center with a double diameter
When the towline 13 is slidably inserted into the 14a and the towline 13 is pulled upward in the rope pipe 7, it is pushed by the socket 15 into the round steel 21 at the lower opening edge of the rope pipe 7 and its inner surface (upper surface).

Connect with b. That is, the tip side pickup rope 10a
And the base end side pickup rope 10b are directly connected, and then the marker buoy 9 is taken out from the storage box 3 and dropped on the sea surface. As a result, the pick-up ropes 10a and 10b are sequentially fed out from the fairleader 4 to the outside of the ship by the gravity of the marker buoy 9. The marker buoy 9 on the surface of the sea is pulled up by a lifeboat or the like and is carried to the ship (towed ship) in which the accident occurred.

Through this series of operations, the towline 13 of the ship is unwound from the reel 8. Then, the towline 13 reaches the towed ship and is fixed on the towed ship. Next, when the ship advances to tow the towed ship, the tow line 13 is pulled and the tow line is pulled.
The stopper 14 is pressed against the round steel 21 at the lower opening edge of the rope pipe 7 by the socket 15 provided at the base end of 13. In this way, the towing load can be held by the rope pipe 7 and the stopper 14 (states of FIGS. 3 and 4). In this way, since the towing load is held by the rope pipe 7, the towing load is not applied to the reel 8, and therefore the reel 8 can be made light in structure.

As described above, the load during towing is a stopper.
Take 14 Therefore, the stopper 14 is the rope pipe 7
It is desirable to evenly abut the lower end opening edge. Therefore, for example, as shown in FIG. 7, a truncated cone surface 14a is formed in the inner peripheral portion of the stopper 14, and the stopper 14 is pulled by the towline 13 to open the lower end edge 7b of the rope pipe 7.
There is also a method of automatically aligning the circular truncated cone surface 14a to bring it into contact with the lower end opening edge 7b (that is, the round steel 21) evenly. The recovery work after the towing is completed by winding the rope 16 which is interposed between the eye plate 12c of the socket 15 and the reel 8 on the reel 8. The final end of the rope 16 is fixed to the reel 8.

As the rope 16 is wound on the reel 8, the tow line 13 and the pickup rope 10b are also sequentially reeled on the reel 8.
Has been wound up. And finally the pickup rope
Remove the shackle 11b of 10b from the shackle 11a of the pickup rope 10a, connect it to the eye plate 12b on the inner surface side of the weatherproof cover 6, further wind the reel 8, and use the weatherproof cover 6 to fix the upper end opening of the rope pipe 7b. Close. When the butterfly-shaped tightening metal fitting 20A is engaged with the metal fitting 20B and tightened, the rubber packing on the inner surface of the weatherproof cover 6 is performed.
19 is pressed against the upper end opening of the rope pipe 7, and the rope pipe 7 is watertightly closed.

When the reel 8 is braked in this state, the inside of the rope pipe 7 can be kept watertight by the weatherproof cover 6. Then pickup rope 10
The shackle 11a of a is joined to the outer eye plate 12a of the weatherproof cover 6. Then, put the marker buoy 9 in the storage box 3.
To be stored. In the second embodiment shown in FIG. 8, the rope pipe 7 is attached so as to be inclined in the rope winding direction.
7 to 7, and with this configuration, the installation position of the reel 8 is limited to an arbitrary position (in the first embodiment, the installation position of the reel 8 is almost immediately below the rope pipe 7). However, in the case of the second embodiment, the installation position of the reel 8 can be selected by selecting the inclination angle of the rope pipe 7).

Further, in the second embodiment, the rope thruster 23 can be used instead of the guide roller, which is advantageous in terms of maintenance. In the third embodiment shown in FIG. 9, the upper end opening of the rope pipe 7 is located in the vicinity of the fair leader 4, and the middle of the rope pipe 7 (almost the center in the length direction) is bent upward. It is shaped like a letter and is attached with an inclination in the rope winding direction.

In the third embodiment, when winding a rope or the like, the bending point A guides the rope and reduces the load on the reel. In addition, guide rails and ropes are not required. Even if the rope pipe is formed in an upward arc shape as a whole, the same effect can be obtained. In the above-described embodiment, the eye plates 12a and 12b are attached to the outer and inner surfaces of the weathertight cover 6, respectively.

Normally, both eye plates 12a, 12b
Since the respective ends of the pickup ropes 10a and 10b are engaged with each other via the shackles 11a and 11b, the respective ends of the pickup ropes 10a and 10b are opened when the weathertight cover 6 is opened to use the towline. The parts are located close to each other on both sides of the weathertight cover 6, and there is an advantage that the work of connecting the pickup ropes 10a and 10b can be easily performed.

However, even if the eye plates 12a and 12b are not attached to the outer surface and the inner surface of the weathertight cover 6, respectively, metal fittings (for example, the base end and the tip end of the pickup ropes 10a and 10b, respectively) can be locked. L-shaped metal fittings) are attached to the outer and inner parts near the upper end of the rope pipe 7, respectively, and the base end and tip end of the pickup ropes 10a and 10b are locked to the metal fittings, respectively. The advantages of In this case, only one of the shackles 11a and 11b is required, which is advantageous in terms of cost.
