Take it in. In addition, in order to finally fix the ship, the mooring rope is moved from the storage section to the stretching section, and a larger amount (for example, about 5 to 10 turns) is taken up to apply tension to the mooring rope. In this way, a fixed output can be obtained on the first floor without applying tension to the mooring ropes that have been taken up in the storage section to prevent the mooring ropes on the upper layer of the storage section from falling into the mooring lines on the lower layer and prevent The generation of friction loss between mooring lines. At this time, a split flange (split flange, split flange) that divides the winding drum into the storage portion and the stretching portion is provided with a gap connecting the storage portion and the stretching portion in advance, and letting The mooring rope passes through the notch, so that the displacement operation from the storage section to the stretching section can be performed. However, in the case of using a steel rope as a mooring rope, because of its large weight and restoring force, tools such as rope hooks must be used, and 2 to 3 people are required to tighten the rope and perform displacement operations. For personnel and operation commanders, there must be 4 to 5 personnel, which has become a labor-intensive and time-consuming operation. In addition, there is also a danger that an operator may be caught in a rope or be ejected during work, or a foot may slip and fall. On the other hand, for example, Patent Document 1 proposes a ship coil with a flange on both sides and a rotation axis in the center. In the ship coil, a right notch circle is provided at the center. Plate and left notch disc, and the notch end of the right notch disc and the left notch disc are connected obliquely with a plate to form a stretch coil drum (stretching part) and a storage coil drum (storage part), And the guide groove is gradually reduced in diameter in an eccentric manner.

The mooring winch 11 is mainly mounted on a ship such as a crude oil tanker and is used in mooring operations. As shown in FIG. 1, a general mooring winch 11 is configured by arranging two rope drums 13 having outer flanges 12 on both sides in a left-right mirror image, and is driven by a central drive motor 14 The driving section 16 constituted by the speed reducer 15 rotates each of the reel drums 13 to take up and unwind the mooring rope 20. In addition, the side where the mooring rope 20 enters relative to the rope drum 13 is set to the front of the mooring winch 11, and the structure and operation of the two rope drums 13 are mirror images of the left and right. The details of the left-side reel drum 13 will be described.

The winding drum 13 is divided into a storage portion 22 and a stretching portion 23 of the mooring rope 20 by a partition flange 21 provided at a central portion in the width direction. Further, as shown in FIG. 2 (A), a notch 24 for displacing the mooring rope 20 from the storage portion 22 to the tension portion 23 is provided on the partition flange 21 at a 180-degree facing position.

As shown in FIG. 1 and FIG. 2 (A), since the guide portion 27 is wound (moved) with respect to the mooring rope 20, the upstream side fixing portion 25 faces the downstream side fixing portion from the outer side fixing portion 25. 26 (the partition flange side is convex) is curved in an arc shape, so that the mooring rope 20 can be smoothly moved along the guide portion 27 without causing the mooring rope 20 to be caught on the way. In addition, when viewing the rope drum 13 from the axial direction, as long as the radius of curvature of the guide portion 27 is about 0.9 to 1.3 times the radius of the outer flange 12, the mooring rope 20 moves along the guide portion 27 when It is difficult to correlate with the mooring rope 20 which has been wound up to the storage unit 22 previously, and the stability and certainty of the displacement operation can be improved, but it is not limited to this. As shown in FIG. 2 (B), in particular when the cable drum 13 is viewed from the axial direction, the guide portion 27 is curved into an arc shape having a curvature radius equal to or greater than the radius of the outer flange 12, that is, the When the guide portion 27 is formed in an arc shape passing through the outside of the outer flange 12, it is possible to reliably prevent the mooring line 20 from drying up. In addition, as the material of the mooring rope displacement tool 10 (the outer fixing portion 25, the partition-side fixing portion 26, and the guide portion 27), stainless steel that is lightweight and has excellent strength and rust resistance can be suitably used, but It is not limited to this. It is also possible to use, for example, a metal having an anti-embroidery treatment on its surface, or another alloy.

Next, the details of the outer fixing portion 25 will be described. As shown in FIGS. 3 (A) and (B), the outer fixing portion 25 has an abutment piece 30 and an opposite piece 31, wherein the abutment piece 30 is an outer flange abutting on the storage portion 22 side of the coil drum 13 On the inner side surface of 12, the facing piece 31 is opposed to the contact piece 30 with an interval therebetween. In addition, a clamping screw 32 is screwed onto the facing piece 31 freely. The outer peripheral portion of the outer flange 12 is inserted between the abutting piece 30 and the facing piece 31, and the clamping screw 32 is locked. The outer fixing portion 25 is fixed to the outer flange 12. At this time, as long as a positioning hole 33 is provided in the outer flange 12 in advance in accordance with the installation position of the outer fixing portion 25, and the ejection pin 35 is driven from the insertion hole 34 formed in the contact piece 30, the outer fixing can be prevented The position of the portion 25 is shifted to be firmly fixed. Further, a fitting pin 36 is provided on one end side of the guide portion 27 in parallel with the rotation center axis of the winding drum 13, and a fitting end is provided on the front end side of the contact piece 30 protruding outside the outer flange 12.合 孔 37. Accordingly, by inserting and removing the fitting pin 36 into the fitting hole 37 (pin fitting), the guide portion 27 can be easily attached to and detached from the outer fixing portion 25.

Since the mooring rope 13 is rotated in the state where the mooring rope displacement tool 10 is installed, the mooring rope 20 wound up in the storage portion 22 is as shown by arrow c in FIG. The right side of the guide portion 27 (partition flange 21 side) moves, and a force is applied in a direction in which the guide portion 27 is pressed from the mooring rope 20 toward the outer flange 12 side, so there is no In the case where the fitting pins 36 provided in parallel with the rotation center axis are detached from the fitting holes 37, the guide portion 27 can be reliably supported by the outer fixing portion 25. Furthermore, in this embodiment, although the fitting pin 36 is provided in the guide portion 27 and the fitting hole 37 is provided in the contact piece 30, a fitting hole may be provided in the guide portion, and A fitting pin is provided on the contact piece.

Next, the details of the partition-side fixing portion 26 will be described. As shown in FIG. 4, the partition-side fixing portion 26 includes a clamp portion 41 having a U-shaped cross section in which the pair of holding pieces 39 and 40 are opposed to each other with a gap therebetween. A clamping screw 42 is screwed forward and backward freely on one side of the clamping piece 40, and an operation handle 43 for rotating the clamping screw 42 is provided on the head of the clamping screw 42. Accordingly, by inserting the outer peripheral portion (corner portion of the notch 24) of the partition flange 21 between the pair of clamping pieces 39 and 40, and rotating the operation handle 43 to lock the clamping screw 42, the partition side can be separated. The fixing portion 26 is fixed to the partition flange 21. At this time, when the operation handle 43 is provided on the storage portion side 22 of the partition flange 21, the mooring line is not moved when the mooring rope 20 is moved along the guide portion 27 to be displaced to the stretching portion 22. When the cable 20 is hooked to the operation handle 43, it has excellent reliability in displacement operation.

Furthermore, the end portions of the clamp portion 41 and the guide portion 27 are connected and fixed by welding or the like, whereby the partition-side fixing portion 26 and the guide portion 27 can be integrated, and the guide portion 27 can be reliably formed. It is held in the partition-side fixing portion 26. Further, as shown in FIG. 4, an end portion on the side of the guide portion 27 of the clamp portion 41 is provided with a contact portion 44 that abuts on an end surface on the upper end side of the notch 24. As a result, as shown by the arrow c in FIG. 2 (B), when the mooring rope 20 moves along the guide portion 27, even if the mooring rope 20 is applied to the guide portion 27 to be directed toward the coil drum, The rotating force of 13 in the direction of rotation (arrow b in FIG. 2 (B)) in the opposite circumferential direction does not move the clamp portion 41, but can maintain the guide portion 27 at a predetermined position and securely secure the mooring line. 20 leads to the gap 24. When winding or unwinding the mooring rope 20, the clamping screw 42 is loosened to release the separation side fixing portion 26, and then the guide portion 27 and the separation side fixing portion 26 are fitted with the fitting pin 36 as The center rotates on the outside of the winding drum 13, and the fitting pin 36 is pulled out from the fitting hole 37 of the outside fixing part 25, so that only the outside fixing part 25 can be left, and the separation can be removed from the winding drum 13 The side fixing portion 26 and the guide portion 27. Even if the mooring line 20 is rolled up or unrolled in a state where the outer fixing portion 25 is mounted on the outer flange 12 as it is, it does not cause an obstacle, and the next installation work of the guide portion 27 can be simplified.

So far, the description has been given of the case where the mooring rope 20 is wound under the coiler 13. The mooring rope is wound on the upper side of the coiler 13 as a modification. Case of coiling above 20. In Figs. 5 (A) and (B), the mooring rope 13 is rotated in the direction of arrow b by rotating the reel drum 13 in the direction of arrow a in Fig. 5 (A), and The upper side of the bobbin 13 is wound up, and this is called upper winding. Although the modification shown in FIGS. 5 (A) and (B) is flipped up and down from FIG. 2 (A) and (B) (the position of the notch 24 of the separation flange 21 is offset by 90 degrees), and corresponds to the coil When the rotation direction of the barrel 13 is reversed, the installation direction of the mooring rope displacement tool 10 is changed, but the structure of the mooring rope displacement tool 10 is the same. The same applies to the point where the partition-side fixing portion 26 is mounted on the downstream side of any one of the notches 24 (the upstream side of the notch 24 with respect to the rotation of the rope drum 13) with respect to the moving direction of the mooring rope 20. According to this, if the reel drum 13 is rotated in the direction of arrow a in FIG. 5 (A) with the mooring rope displacement tool 10 installed, the mooring rope 20 wound in the storage portion 22 can be moved along The guide portion 27 is moved toward the partition flange 21 side (in the direction of the arrow c) and guided to the notch 24. In addition, the mooring rope 20 can be automatically displaced from the storage portion 22 to the stretching portion 23 through the notch 24, and can be wound around the stretching portion 23 to generate a predetermined tension. Furthermore, in this case, the mooring winch may be configured by arranging the two coil drums in a left-right mirror image.
