Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an operating device for a boat winch for a watercraft.

Conventional structure and its problems According to the proposed amendment to Chapter 1 of the International Convention for the Safety of Life at Sea (SOLAS amendment), ships must contain enclosed boats (lifeboats). In addition, in the event of a distress, the boat must be lowered and launched by operating the boat winch on the boat davit from inside the boat after all crew members have boarded the boat.

Conventionally, when lowering and launching an enclosed type watercraft, a person directly holds a winch brake operating cable that has been placed inside the watercraft in advance to apply tension.

However, when a watercraft lands on water, the winch brake operating cable must be released quickly and at an appropriate timing, and there has been a problem in that it is difficult to do this reliably and efficiently by human operation. Additionally, when the boat is released under load (for example, when the boat is released while suspended), a large tension is applied to the winch brake operating cable, which may cause injury to the person holding the operating cable. There was a problem. Therefore, it has been desired to develop an operating device that can safely and reliably operate a boat winch for a watercraft.

Purpose of the invention An object of the present invention is to provide an operating device for a boat winch for a watercraft that solves the above-mentioned conventional problems.

Structure of the Invention In order to achieve the above object, the operating device of the boat winch of the present invention has a cable through hole whose open end on the cable insertion side is formed in a funnel shape, and is provided at an appropriate position on the top plate of the boat. A cable penetrating fitting for guiding a winch brake operating cable let out from a boat davit for launching the watercraft into the watercraft, and a plurality of cable fittings for zigzagly intertwining the ends of the winch brake operating cables led into the boat through the cable penetrating fitting. This configuration allows the winch brake operation cable to be easily tensioned with a small amount of human power by the handle equipped with the rope fastening metal fittings. In addition, when the boats are removed all at once, the handle can be released naturally by using the force acting on the boats, thereby preventing accidents resulting in injury or death.

Embodiment and operation An embodiment of the present invention will be described below based on the drawings.

First, the general structure of a boat davit is shown in FIGS. 1 and 2. In the figure, 1 is a frame for a boat davit, 2 is a pair of left and right cradles whose base ends are pivotally supported on the frame 1, and 3 is an enclosed type boat whose bow ends are suspended from both cradles 2. A boat winch 4 serves to swing both cradles 2 and lower the boat 3 to the sea, and its operation is performed by an operating device 5 provided inside the boat 3. That is, the boat suspension ropes 8 corresponding to the left and right cradles 2 are wound around the two drums 6 and 7 of the boat winch 4, and one of the drums 7
A winch brake operating cable 10 for operating a rotary winch brake operating rod 9 is wound around the
This winch brake operating cable 10 is guided into the boat 3 via a pulley 11 provided at the tip of the operating rod 9 and a plurality of pulleys 12 provided at other appropriate locations. Therefore, when tension is applied to the winch brake operating line 10 by the operating device 5 in the boat 3, the operating rod 9 is rotated upward against the spring 13, and is switched from the OFF state to the ON state. Become. Reference numeral 14 indicates a boat boarding platform provided on the cradle 1, and 15 indicates a ladder used by the crew to climb onto the boat boarding platform 14.

Details of the operating device 5 are shown in FIGS. 3 to 6. In the figure, 16 is a bolt 17 attached to the top plate of the boat 3.
The cable penetration fitting 18 attached through the cable penetration hole is a funnel-shaped opening end on the cable insertion side. 19 is a ring-shaped gasket glued to the lower end surface of the cable penetration fitting 16; 20 is a plug screwed into the end of the cable penetration hole 18 on the cable exit side; suspended via a rope 22 from a mounting bracket 21 attached to the
Although FIG. 6 shows the plug 20 screwed into the cable through-hole 18, it goes without saying that it is normally removed.

Reference numeral 23 denotes a triangular ring-shaped handle that holds the winch brake operating cable 10 guided into the boat 3 through the cable penetration fitting 16, and has a plurality of cables on one side for twining the ends of the winch brake operating cable 10 in a zigzag pattern. A stopper 24 is fixedly provided.
Moreover, a cable through hole 25 for passing the winch brake operating cable 10 is formed in the upper part. Each of the cable fixing fittings 24 has a short cylindrical shape, and a groove 26 is formed on the outer circumferential surface of the cable fittings 24 so that the cable can be properly fixed. This handle 23 is also similar to the stopper 20,
It is suspended via a rope 28 from a mounting fitting 27 attached to the top plate of the boat using the bolt 17 of the cable penetration fitting 16.

As described above, the operating device 5 is mainly composed of the cable penetrating fitting 16 and the handle 23, but when connecting the winch brake operating cable 10 to the operating device 5, first the tip of the winch brake operating cable 10 is connected to the operating device 5. is passed through the cable through hole 18 of the cable penetration fitting 16, then through the cable penetration hole 25 of the handle 23, and then tied around the cable stopper fitting 24 in a zigzag manner. As a result, even if the winch brake operating cable 10 is pulled with a certain amount of force, the winch brake operating cable 10 will not come off from the handle 23 due to the frictional force of the cable stopper 24. On the other hand, if a strong tension is applied to the winch brake operating cable 10, the handle 23 will be pulled up and hit the lower end of the cable penetrating fitting 16, and then the winch brake operating cable 10 will overcome the frictional force of the cable stopper fitting 24 and move away from the boat. It will slip through outside.

Next, the overall operation will be explained.

First, in an emergency such as a shipwreck, the crew climbs the ladder 15 to the boarding platform 14 and boards the boat 3. next,
When a crew member pulls the handle 23 in the boat 3, the tension acting on the winch brake operating cable 10 causes the brake operating rod 9 to rotate upward against the spring 13, and the boat winch 4 is turned on. . Then, the boat suspension line 8 and the winch brake operating line 10 are let out from the boat winch 4 by the weight of the boat 3, and first, both cradles 2
will be swung outboard to a nearly horizontal position. Then, when both cradles 2 fall down, the boat 3 begins to descend directly below. As a result, the boat 3 reaches the sea, but it goes without saying that during this time, the occupants of the boat apply or disengage the brakes as appropriate using the handle 23.

Then, when the crew member reaches close to the sea, the crew member releases the handle 23, that is, the boat winch 4 is activated.
When the OFF state is set and the edges of the boat suspension cables 8 are cut all at once using a boat release device (not shown), the handle 23 hits the lower end of the cable penetration fitting 16 as the boat 3 descends, and the winch brake operating cable 10 is immediately released. It will slip out of the boat. At this time, since the handle 23 is suspended from the fitting 27 by the rope 28, it remains suspended in the vicinity without falling, as is clear from FIG. After the cable is released, a plug 2 is inserted into the cable penetration hole 18 of the cable penetration fitting 16 to prevent wind, rain, and outside air from entering the boat.
0 screwed together.

Effects of the invention As described above, according to the invention, it is possible to easily apply tension to the winch brake operation cable let out from the boat davit with a small amount of human power by using the handle equipped with the rope stopper, and also to apply tension to the winch brake operation cable that is let out from the boat davit. At the time of detachment, the handle can be naturally released using the force acting on the watercraft, thereby preventing accidents resulting in injury or death. Further, since the opening end on the cable insertion side of the cable penetration hole of the cable penetration fitting is formed in a funnel shape, it is possible to cope with the case where the angle at which the winch brake operation cable is taken into the boat is not constant.
