Description

[Detailed description of the invention] The present invention relates to a rope anchoring device used for ship mooring work, etc., and is designed to safely and easily anchor and unmoor ropes from tugboats or quays to and from ships. This is the purpose.

When the ship is towed by a tugboat or when the ship is moored to a quay, etc., it is necessary to anchor the mooring line to the vessel from the tug board or quay.

Conventionally, bollards, bits, etc. were installed on the hull deck as means for mooring such cables, so when moying the cables, the Moyai cable was lowered from the ship to the tugboat.
The moyai cable is tied to the tip of the mooring cable, and when the moyai cable is wound up using a winch etc. and the tip of the mooring cable reaches the ship, the end of the mooring cable, which has been manually made into an eye by the crew, is tied directly to the bollard. The reality is that when the vessel is stopped and evacuated, the mooring lines that have been moored are removed manually by the ship's crew and handed over to the tugboat.

These operations involve moving while carrying mooring ropes that are considerably thick and heavy, which requires labor and poses a safety problem, making it impossible to rationalize the number of ship personnel. There was also a reason.

The present invention has been made in view of these problems and proposes a mooring cable locking device that saves labor and manpower in mooring work.

Its structure is such that a recess is installed on the outer panel of the hull at a position above the sea surface that takes into consideration the height of tugboats and quays, etc., and a hydraulic cylinder is installed at the bottom of the recess so that it faces upward and its tip does not protrude from the bottom. A retaining portion is provided at the top of the recess so that the tip of the ram engages with the engaging portion when the hydraulic cylinder is extended.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a schematic cross-sectional view of a ship equipped with the present invention, and FIGS. 2 and 3 show enlarged views of section A circled in FIG. 1.

The mooring device 1 is provided with a recess 5 on the outer plate 3 of the ship's side 2 at a position above the sea surface 4 in consideration of the height of the tugboat and the quay, and the bottom 6 of the recess 5 is strong enough to be moored with the mooring line 7. With the hydraulic cylinder 8 facing upward, the tip is at the bottom 6.
The upper part 9 of the recess 5 is provided with a retaining part 10 at a position corresponding to the hydraulic cylinder 8, so that the hydraulic cylinder 8 is not protruded. The height position is such that the tip of the ram 11 can engage with the retaining part 10 when the under 8 is extended.

The tip of this ram 11 is sloped so that the mooring cable 7 can be easily removed.

The hydraulic cylinder 8 is provided with respective hydraulic pipes 12, and its base end is supported by a bracket 13.

Further, a torque hinge 15 for opening and closing the door 14 is provided on the outside of the upper part 9 of the recess 5.

When the door 14 is closed, it becomes flush with the outer panel 3 and watertightness is maintained.

The hydraulic cylinder 8 and the torque hinge 15 are operated by remote control.

Note that in a ship such as a car carrier with little change in water intake, the locking device 1 is always located above the full load water level, so the door 14 and the torque hinge 16 may not be provided.

For ships with large changes in water intake, locking devices 1 are installed separately for fully loaded and lightly loaded ships.If installed on a lightly loaded ship, the locking device 1 will be 4 below sea level when fully loaded, so it will be necessary to install a watertight locking device as in this proposal. It is necessary to provide a door 14 and a torque hinge 15.

Next, to explain the operation procedure, when the tugboat comes alongside the ship, the door 14 is opened by operating the torque hinge 15 by remote control from the ship side.

At this time, the hydraulic cylinder 8 is normally in the stored state, so
The hydraulic cylinder 8 is operated by remote control from the ship side, and the height position of the tip of the ram 11 is extended to the extent that the mooring line 7 can be locked therein.

Then, from the tugboat side, the eye-processed tip of the mooring line 7 is engaged with the ram 11 in the recess 5 using a davit (not shown) or the like provided on the tugboat.

Next, the hydraulic cylinder 8 is activated by remote control from the ship side, and the ram 11 is extended until the tip of the ram 11 engages with the engaging portion 10 provided in the upper part 9 of the recess 5.

When leaving, hydraulic cylinder 8 is activated by remote control from the ship side.
When the mooring line 7 is placed in the stored state, the mooring line 7 is automatically removed.

Next, the torque hinge 15 is actuated from the ship side, the door 14 is closed, and the mooring work is completed.

In the above-described embodiment, the mooring cable is directly locked to the ram of the hydraulic cylinder, but a structure may also be adopted in which a cylindrical body is integrally attached to the tip of the ram and the cable is locked to this cylindrical body. .

In this case, there is a disadvantage that the section equipped with the locking device becomes larger, but since the diameter of the ram can be reduced and a cylinder with a larger diameter can be used, the hydraulic cylinder can be made smaller and configured to withstand large loads. There is an advantage that it can be done.

As described above, the present invention can reduce the number of ship crew members because it is only necessary to remotely operate the torque hinge and hydraulic cylinder when the mooring line is engaged and detached.

In addition, on the tugboat side, the mooring line can be easily rammed by using a davit or the like on the tugboat, and there is no need to remove it, making the operation easy.

Furthermore, even if the ship shakes during mooring, there is no fear that the mooring line will separate from the ram, making it safer.

Therefore, it has a great effect on shortening mooring work time and saving labor costs.
