Description

[Detailed Description of the Invention] The present invention relates to a net lifting device, and more particularly, to a net lifting device for a rod receiving net.

Net lifting work in the saury rod seine fishery requires a series of different tasks: first, winding the wire using a lifting line winch, and then lifting the net using a lifting net roller.

However, as shown in FIG. Using a sheave 6 installed on the deck as a guide, the wires were collected into a central separation guide member 7 called a soroban, and each wire was wound from this central separation guide member 7 onto a winch drum 8 installed on the hull 5. . Having such a large number of wires running over the working deck obstructs the actions of the sailors, and sometimes there is a risk that the sailors may be injured by these wires.

Conventionally, to solve these problems,
A wire guide groove is provided at the end of the net-lifting roller, and a winch drum for winding the wire is installed on the deck directly below this to prevent the wire from creeping onto the working deck of the ship. Proposed. However, with this type of equipment, if the wire becomes detached from the groove, there is a risk of significant damage to the rubber net-lifting rollers, and especially during net-lifting, the rod-receiving net may become caught on the winch drum, or the wire may become unrolled. There is a problem that not only is there a risk of the net breaking if the winch drum is exposed, but it is also extremely dangerous to have the winch drum exposed on the deck. has not been resolved at all.

The present invention was devised in view of the above circumstances, and uses a simple yet rational means. Specifically, each bearing body has a hollow structure, an opening is provided in the lower side of each bearing body, and the opening is The present invention aims to solve the problems of the prior art by arranging a plurality of guide rollers so as to surround the net, and to provide a net lifting device that can sufficiently improve workability and safety.

Next, details of the embodiment of the present invention will be explained with reference to FIGS. 2 to 4.

FIG. 2 is an explanatory diagram showing the wire guiding state, FIG. 3 is a front view of the net lifting device, and FIG. 4 is a side view of the bearing body. Reference numeral 11 denotes a hollow bearing body which is arranged at a predetermined interval on the deck of the hull 12 and has a tiltable bearing part 11a pivotally supported on the upper part, and in the upper part between the bearing bodies 11a, A hoisting net roller 14 rotatably driven by a drive source such as a hydraulic motor 13 is mounted on a shaft. A guide sheave 17 for a wire 16 loosely fitted to the shaft 15 rotated by the hydraulic motor 13 is built into the upper part of each bearing part 11a.
A notch 18 for guiding the wire 16 to the guide sheave 17 is formed in the upper part of 1a.

As shown in FIG. 4, a guide roller 19 parallel to the side direction of the hull 12 is mounted on the inner lower part of the bearing body 11, and furthermore, on both sides of the lower end of the bearing body 11, Openings 20 are formed in the surfaces facing the bow and stern sides of the hull 12, respectively, and the guide roller 19 is mounted on an axis so that the circumferential surface of the guide roller 19 faces the center of the opening 20. Four guide rollers 21a, 21b, 22a, 22 are provided to fit the upper and lower edges and the left and right edges of the opening 20.
b is pivotally supported by a bearing body 11. The ends of all the wires 16 are connected so as to be wound onto a winch drum 23 provided on the hull of the ship via a central separation guide member 25 called a soroban similar to the conventional one. In the figure, 24 is a knock pin for fixing the tilting of the bearing portion 11a.

In the above embodiment, the openings 20 are provided on both sides of the lower end of the bearing body 11, but the wire 16 guided through the other bearing body 11 is provided in this bearing body 11 so that the wire 16 guided through the other bearing body 11 can pass therethrough. 2nd and 3rd
As shown in the figure, the opening of the bearing body 11 located at the end may be provided on either side.

Since the present invention is constructed as described above, the wire is guided by the guide sheave built into the upper part of the bearing body, and unlike the prior art, the wire does not escape from the sheave and damage the net lifting roller. Of course, the wire is guided downward inside the hollow bearing body, and is also guided to the outside through an opening provided at the bottom of the bearing body, directly below the net lifting roller, and on the deck surface. It crawls along the road until it reaches the winch drum. Therefore, work on the deck is not obstructed by wires as in the prior art, and accidents that endanger the crew or damage the net can be avoided. Furthermore, multiple guide rollers are provided surrounding the opening, so no matter how the wire runs, the wire will come into contact with the bearing body and will not be damaged or cut, ensuring smooth operation. It has great practical effects, such as the ability to provide guidance.
