Description

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

[Prior art]

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

However, all the wires in the rod net are first guided by a guide sheave installed on the top of the bearing body, and then collected in a centralized separation guide member called a sorovan, with the sheave etc. installed on the deck as a guide. Each wire was then wound from this central separation guide member onto a winch drum provided on the ship's hull. (For example, Publication of Utility Model Publication No. 52-30317) [Problem to be solved by the invention] As mentioned above, having a large number of wires crawling on the working deck obstructs the actions of sailors and sometimes causes problems. However, there was a problem in that these wires caused sailors to become erect.

In order to solve these problems,
A fishing net winding device as disclosed in Publication No. 33881 has been proposed, but this device has a floating roller for a wire guide at the end of the net roller, and a fishing net winding device that is pivotally supported on a support seat directly below this. It has been proposed that a frame be installed to prevent wires from creeping onto the working deck of the ship. However, with this type of equipment, if the wire comes off the floating roller, there is a risk of significant damage to the rubber net lifting rollers, and especially when the net is being lifted, the rod receiving net may get caught on the net reel, In addition, there remains the issue that not only is there a risk of the net becoming entangled and causing the net to break, but it is extremely dangerous for workers to have the net spool exposed on the deck. has been done.

The purpose of the present invention was made in view of the above-mentioned circumstances. Specifically, the purpose of the present invention is to provide a simple yet rational means, specifically, to provide a structure in which each hollow bearing body is driven by a drive source such as a hydraulic motor. By incorporating each winch drum and winding the wire guided through the guide sheave provided on the upper part of the bearing body, the above-mentioned problems of the conventional technology are solved, and workability and safety are improved. The purpose is to provide a net-lifting device that can be used in a sufficient manner.

[Means to solve the problem]

The structure of the present invention, which solves the problems of the prior art, is that a large number of bearing bodies are arranged on the deck at predetermined intervals, a wire guide sheave is built into the upper part of each bearing body, and each bearing In a net lifting device in which a long net lifting roller is mounted between the bodies, each of the above-mentioned bearing bodies has a hollow structure, and inside each of these bearing bodies, a roller is rotatably driven by a drive source such as a hydraulic motor. The present invention is characterized in that a winch drum is built into each of the guide sheaves at a lower position.

〔Example〕

The embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a front view of the net lifting device with a part omitted, and FIG. 2 shows a cross section taken along line A--A in FIG. 1. 1 is a hollow bearing body disposed at a predetermined interval on the deck of a ship (not shown);
A net lifting roller 3 rotatably driven by a drive source such as a hydraulic motor 2 is mounted on an upper portion of each bearing body 1 . And on the upper part of each bearing body 1,
A wire guide sheave 5 loosely fitted to the shaft 4 rotated by the hydraulic motor 2 is built-in.
Furthermore, a notch 6 is formed in the upper part of each bearing body 1 to guide the wire to the guide sheave 5.

Reference numeral 7 denotes a winch drum that is built-in and pivotally supported in the inner lower part of each of the bearing bodies 1, and each of the winch drums 7
are each fixed to a shaft 9 that is rotationally driven by a drive source such as a separate hydraulic motor.

Furthermore, by making the guide sheave 5 freely slidable in the axial direction of the shaft 4, the wires wound around the winch drum 7 can be distributed and guided. This allows the wire to be guided without frictional resistance. In the figure, reference numeral 10 denotes a seat for supporting the bearing body 1, and the bearing body 1 is pivotally supported by a shaft 11 on the seat 10 so that it can be tilted by a predetermined angle toward the sea side and the ship side. The inclination angle is maintained by the holes provided in the bearing body 1 and the seat 10.
2 are made to coincide with each other, and a dowel pin 13 is inserted therethrough in common.

When winding the wire, one hydraulic motor 8 is driven, and when lifting the net, it is sufficient to stop this hydraulic motor 8 and drive the other hydraulic motor 2, and mechanisms such as a switching clutch are omitted. , a device with good workability is provided.

[Effect of idea]

As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) Since the wire is guided by a guide sheave built into the upper part of the bearing body, it goes without saying that the wire will not come off the sheave and damage the net lifting roller, unlike in conventional technology. (b) The wire is properly wound around the winch drum built into the lower part of the hollow bearing body, and the wire is completely guided inside the bearing body without being exposed on the hull side, unlike in the prior art. Since the winch drum is closed, there is no risk or hindrance to the crew's work, and there is no net entanglement in the winch drum.

Claims (1)

[Claim for Utility Model Registration] A large number of bearing bodies are arranged on the deck at predetermined intervals, and a wire guide sheave is built into the upper part of each bearing body, and a long wire is installed between each bearing body. In a net lifting device having a net lifting roller mounted on an axis, each of the bearing bodies has a hollow structure, and a winch drum rotatably driven by a drive source such as a hydraulic motor is placed inside each bearing body to guide the winch drum. A net lifting device characterized in that each of the net lifting devices is built in a position below a sheave.
