The present invention relates to a purse shaped mesh link used for fishing nets, chains and rollerhead purse shaped links.

In the past, the grommets were used to be movably connected to be supported toward the length of the rigid support cable at the margin of the fishing net, and the grommets were continuously provided adjacent to the other grommets so that each grommets connected to one part of the fishing net. The entire fishing net is supported by all the hoops, and the floats attached to the edges of the fishing net support the fishing net floating on the surface of the sea, but the fishing net is continuously released from the stern or submerged in the sea from the stern of the ship. When the site is rolled up, the grommet supports the fishing net.

However, under such working conditions, the grommets are severely worn or crushed due to the extremely heavy load conditions and load distribution from the fishing net to the support cable, and for this reason, the grommets have an upper portion. Rigid cross member is provided on the opposite side is coupled to the opposite side, while the rope is rounded at the lower end is provided with a rigid cross member coupled to the lower end at the upper end of the claw It is formed so as to be opened through the arranged lower end or purse-shaped cable, which cable is mounted on the rim frame itself, or in some cases on a rigid crossbar.

Since the purse-shaped cable is tied or laid on the semi-circular rigid lower end of the fender frame, when the fender is used, there is no space for the fender to be badly worn and crushed and cracked due to continuous fatigue. In addition to damage or damage, the wallet-like cable is also damaged, such as the gasket.

In addition, since there is no moving space in the grommet part, the opposing part is applied by an operator to the outer peripheral surface of the rigid bar together with the lower end part or the end bent in a curve to enable the sliding of the cable, but the grease or oil applied This soon dissipates and flows from metal to metal.

Therefore, in order to compensate for this, friction preventing means are used to reduce wear and damage between the metal parts of the support part, but such a brace should be provided with a lubricating means, and the worn or damaged part immediately In order to get acquainted, the structure must be disassembled.

In order to solve this problem to some extent, JANG ET AL is registered in US Patent No. 5,119,735, which has a roller to reduce the wear of the grommets when the fishing net is rolled up or loosened. In addition to being provided, the rollers are used to insert and remove cables, which may be removed by shrinkable sleeves, thereby improving the conventional problems but several problems still exist.

In other words, to remove the link from the cable, the detent must be pressed, the slide slides backwards, and once the slide is out of position, after the cable has been removed, the link must be manually closed. The work process requires extra time to induce warm water temperatures and the cost of immediately placing the fish into the fish storage tank, as well as high labor intensity because the detent must be pressed by hand. Will be required.

In addition, if the link is suddenly opened in the flow of fishing nets, the open purse-shaped mesh link acts like a fishing needle and severely tears the fishing net, so that the fishing boat cannot be used before repairing it. If a large hole is drilled in the fish, the fish will escape through it, reducing production and taking time to repair the entire fishing net set due to damaged fishing nets.

Another problem is that when the purse-shaped mesh link is removed from the purse-shaped cable tension of the fishing net, the operation is very dangerous because the link must be removed before removing the link from the cable by hand. Temporarily releasing the mechanism to remove dents from the fishing net may cause the operator to be injured while the link is removed from the cable.

Then, after the link is released from the cable, the worker hangs the hook on the hook in the davit, which is a column for hanging the link. If the link is not properly placed on the hook, the fishing net is pulled toward the boat, so the link is removed from the hook. It can even come off or hit the worker.

Also, when the link spans the davit, it is released from the tensioned fishing net to the purse shaped mesh link to alleviate the tension of the mechanism from the fishing net.

If the link is improperly hung on the davit, the movement of the tightly supported mechanism causes the link to come off the hook as well as to injure the operator who manipulates the davit.

Therefore, the present invention is invented to solve such a problem, at least 20 ° to remove the purse-shaped emanation link from the purse-shaped cable in a one-step process and hitting the purse-shaped mesh link with a hammer or wood hammer. For example, about 30 ° will open automatically and move away from the purse cable.

The present invention for achieving the above object is provided with a roller head to rotate about 35 ° open and the roller head, even if the roller head is pulled out to the edge, the roller head is automatically released by the spring force of the spring after the cable It is structured to be closed.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a purse shaped mesh link bar, the purse shaped mesh link 10 is composed of two main parts, the body 20 and the roller head 30, the body 20 is large Has a U-shaped cross section is formed and the latch device 22 is fixed to the upper portion of the body 20 is connected to the body 20 by the latch pivot 24, as shown in FIG. As such, a spring 26 is provided that is normally compressed to hold the latch device 22 in place.

In addition, the main part of the roller head 30, which is connected to the body 2 via the head pivot 32, is a roller 34, which is a roller head by the roller shaft 36. 30, the roller shaft 36 is placed in place by the dowel 38.

2 shows the removal of the purse shaped mesh link 10 from the cable 8, the back of the latch device 22 with the spring 26 attached to it which strikes the operator. This is because the 22 is pivoted around the latch pivot 24, and the pressure of the cable 8 applied to the roller head 30 is rotated clockwise around the head pivot 32. In this case, the latch device 22 slides toward the concave groove 40 as shown, while the roller head 30 is rotated so that the cable 8 slides out by the roller 34. As you go out, the purse shaped link 10 is free.

The amount of rotation of the roller head 30 relative to the head pivot 32, which is required of the cable 8 for the roller 34 to slide, is the cable 8, the roller head 30, and the roller 34. Preferably, the inclination ratio of the rotation of the roller head 30 with respect to the head pivot 32 should be greater than about 0.4 since it depends on the coefficient of friction between.

As described above, the first step of the purse forming receptacle link 10 which is separated from the cable 8 after the first step of hitting the clasp rear end 28 of the clasp device 22 is required time and worker stability. In terms of efficiency.

The outer diameter of the roller 34 according to the present invention is about 3 inches (INCHES), the outer diameter of the roller shaft 36 is about 5/8 inches (INCHES), which is about 4.8 for the roller 34 and the roller shaft 36 In this large ratio, the amount of torque applied to the roller 34 is increased and the roller 34 is prevented from being constrained. ) It causes more wear on the roller and the roller bearing is broken quickly.

In addition, such a large ratio can overcome the frictional force caused by corrosion that occurs quickly in an environment such as the sea, and when the roller 34 having an outer diameter smaller than the outer diameter of the roller shaft 36 is used, It is possible to prevent the confinement of the roller 34, which causes the sliding of the wear 34 while creating a groove in the 34).

To work in environments such as seas where corrosion quickly occurs without additional lubricant supply, the roller bearing ratio should at least exceed about 3: 5: 1.

Figure 3 shows another embodiment bar, the body 20, the roller 20, which is connected to the body via a shaft (not shown) is used to extend the life of the edge of the body 20 The service life of the purse shaped mesh link 10 is greatly increased and the cable 8 can be used for a long time.

In addition, the body 20 is provided with an upper concave edge groove 21 and a lower concave edge groove 23, the upper concave edge groove 21 to protect the latch device 22 to be springed in place. The lower recessed groove 23 prevents the latch device 22 from being opened by an accident.

Between the lower concave edge groove 23 is properly designed to apply a force to the latch device 22 to loosen the roller head 30 is hammered, spring 26 is latched in the locked position 22 The roller head 30 is rotated so that the purse shaped receptacle 10 is locked in the clockwise position when the cable 8 is released from the purse shaped receptacle 10 when the cable 8 is released. do.

Then, the compressed spring 26 is to re-constrain the roller head 30 so that the latch device 22 prevents the roller head 30 from being opened due to an accident, which is required by the worker's manual work. It will eliminate your work.

Figure 4 shows another embodiment in which the outer diameter of the roller 34 is concave, this concave shape is a point of the fishing net 70 inserted into the purse-shaped mesh link 10 and the roller 34 The radius of the cable 8 is almost equal to the distance between the points of the cable 8 in contact with the surface of the cable (8). This shape is such that the cable (8) has a roller ( Since it is pulled intersecting with 34, it is not moved axially along the roller 34, thereby increasing the area that is not worn.

Cylindrical rollers 34 tend to move the cable 8 toward any portion of the roller 34 end that causes the cable 8 to wear off the end of the roller 34 and the body 20, but V The shaped roller 34 moves the cable 8 toward the center of the roller 34 so that only a portion of the roller 34 is worn out rather than worn out as a whole.
