Description

{Fish traps and nets combined use pulling up machine}

The present invention relates to a net hoist, and more particularly, to a net hoist combined with a trap and drift net, which prevents slipping of a rubber roller for pulling a main line of a net inserted into the outer surface of a main roller device, and increases friction between a sub-driving roller device having a plurality of protrusions and a driven roller, thereby ensuring stable pulling of a heavy-load net and preventing maritime accidents in advance.

In general, a seine net is a mechanical device that is fixed to the deck of a ship, connects a net or trap such as a gillnet to a rope, lowers it to the sea floor, and after a certain period of time, catches the fish caught in the gillnet and lifts them up.

These nets can cause safety accidents, such as when the worker's body gets caught between the drive roller and the driven roller due to slipping of the driving roller that pulls the rope. According to the Tongyeong Coast Guard, there was an accident where a couple died after getting entangled in a net trap off the coast of Mijo Port in the South Sea.

A netting machine according to the prior art is a device that comprises a transmission connected to a driving motor mounted on one side of a housing, a driving gear connected to and driven by an output shaft of the transmission, and first, second, and third winding driving rollers each equipped with an elastic band that is rotated by the driving gear, and some of the rollers rotate in the same or opposite directions to raise a net.

These conventional hoists use first, second, and third winding rollers equipped with elastic bands, so the elastic bands wear out with use, causing a slipping phenomenon, making it impossible to hoist a high-load net. As a result, workers may be dragged into the hoist while holding the net, causing safety accidents due to fingers or body parts getting caught in the rollers, or the main line of the net may come off.

To solve this problem, KR [1] Utility Model Publication (Y1) No. 20-0310101 and [2] No. 20-0321132 have been proposed, but the technology of [1] above has a problem in that when a fishing line is extended by relying on the frictional force of the rubber roller (38) and the air tube (43) of the driving roller device (30) and the driven roller device (40), the fishing line, which is subject to a high load and soaked in water, exceeds the frictional force of the rubber roller (38) and the air tube (43), causing a slipping phenomenon. In addition, the technology of the above [2] is a technology that complements the problem of the above [1], and an auxiliary driven roller device (50) is added in which an air tube (53) that comes into contact with the rubber roller (38) of the driving roller device (30) is assembled, and a tension spring (56) is assembled between a bolt (55) that is fixed by a nut (57) through an extension (54a) integral with the auxiliary member (54) and a bolt (12a) of the fixing member (10). However, there is still a problem in that the rubber roller (38) inserted into the outer surface of the driving roller device (30) is worn out due to use, and the rubber roller inserted into the driving roller device becomes loose, causing a slipping phenomenon, which makes it impossible to pull the main line of the net, or maritime safety accidents still occur.

Accordingly, the purpose of the present invention is to provide a hoist for use with both fish traps and drift nets, which is designed to solve the problems of the prior art, by preventing the slipping phenomenon of a rubber roller for pulling a main line of a net inserted into the outer surface of a main drive roller device, and a sub-drive roller device formed of solid rubber and a driven roller having a plurality of protrusions, thereby preventing the slipping phenomenon of the hoist when pulling a heavy load net such as a fish trap or drift net, thereby ensuring stable towing and preventing maritime safety accidents in advance.
