Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an anchor pulling jig in an anchor structure of a small boat such as a fishing boat.
[0002]
[Prior art]
In order to stop fishing at a required point and enjoy fishing, the fishing boat lowers the anchor from the boat S and digs it into the seabed to suppress the swaying of the boat and prevent the flow from the wind. That is, when this anchor structure is described with reference to FIG. 1 according to the present invention, the anchor L (see FIG. 3) that is attached to the row line a from the ship S is generally released into the sea and digs into the seabed G. Is. The anchor L is pulled up by traversing the cable a.
[0003]
As shown in FIGS. 1 to 3, the anchor L is provided with a pull rod 2 extending at the front side of the anchor body 1 at the base of the anchor main body 1 that bites into the seabed G, and A connecting structure is common.
[0004]
In this structure, when the anchor L is pulled up, the anchor main body 1 cannot be pulled out from the sea floor unless the pulling rod 2 is pulled with a considerable force, and the anchor main body 1 may be sandwiched between rocks at rocky places or the like and may not come out at all. In this case, there is no choice but to leave the anchor, which leads to marine pollution.
[0005]
For this reason, conventionally, even when the pulling force from the pulling rod 2 cannot be removed, the pulling jig A is interposed between the pulling rod 2 and the pulling cord a so that the anchor L can be pulled up. From A to the base of the anchor body 1, the pulling cord b is guided and locked, and when the pulling force of the pulling cord a exceeds a required value, the pulling jig A releases the connection with the pulling rod 2. Many techniques for transmitting the attractive force to the lifting cable b have been proposed. Examples thereof include those described in JP-A-63-31892, JP-A-62-284092, JP-A-8-40353, and the like.
[0006]
In each of these known technologies, the above required value is set slightly higher than the attractive force necessary for mooring the ship S, such as offshore, and when the anchor L is pulled up, the anchor rope is pulled with a force greater than that required value. When a is pulled, the pulling cord A separates the pulling cord a and the pulling rod 2, and the pulling cord a exerts an attractive force on the pulling cord b to pull the root of the anchor body 1. Since the pulling force at the base works in the direction of lifting the anchor body 1, the anchor body 1 can escape from the seabed and be pulled up.
[0007]
[Problems to be solved by the invention]
The setting of the predetermined value in each of the above known techniques is performed by a spring or a cutting pin, and the adjustment needs to be performed by replacing the spring or the pin itself. Moreover, since it is comprised with a simple thing like the ring which makes the traction jig | tool A, the effect | action is not stable, and the anchor line L and the pulling rod 2 are separated during mooring, and the anchor L is pulled out Has occurred.
[0008]
This invention makes it a 1st subject to stabilize a traction effect | action, and makes it the 2nd subject to enable it to adjust the said predetermined value easily.
[0009]
[Means for Solving the Problems]
In order to achieve the first object, according to the present invention, a piston and an operating rod projecting from the piston to the other end side are provided in a cylindrical body connected at one end to the pulling rod or the rope. A locking block that can be freely moved into and out of the cylindrical body is provided at the protruding end, and an engaging hole is formed in the locking block, into which an engaging element connected to the scoring cord or pulling hook is detachably fitted. The stop block always enters the cylinder by a spring that urges the piston, and the engagement hole is covered by the cylinder so that the engagement element cannot be detached. Te, piston when moved required length against the spring, Ru Nodea the engagers opened from the cylindrical body to the extent to which the engagement hole exits are engaging elements has adopted a configuration in which withdrawal.
[0010]
The pulling force of the rip cord that allows the piston to move the required length is set to the predetermined value, and when the pull force reaches the predetermined value, the engaging element is released, the pulling force of the rip cord extends to the pulling cord, and the anchor body smoothly Can escape from the seabed.
[0011]
In order to achieve the second object, according to the present invention, a spring seat through which the operating rod passes is provided in the cylinder so as to be movable in the cylinder axis direction, and the spring is interposed between the seat and the piston. Then, a pin protruding from the seat to the outer surface of the cylinder is provided, and a long hole in the cylinder axis direction in which the pin moves is formed in the cylinder, and a nut is screwed into the outer surface of the cylinder. the pins as can abut, Ru Nodea where the configuration capable of adjusting the contact position of the pin the position of the nut. If it does in this way, the said predetermined value can be adjusted by position adjustment of a nut, and it can respond to the state of a seabed.
[0012]
[Embodiment]
First, the anchor L will be described. As shown in FIG. 3, a bearing 3 is erected at the base of the triangular plate-shaped main body 1, and a bearing block (not shown) is rotatable on the bearing 3 via a shaft 4. The L-shaped swing piece 5 of the pulling rod 2 is fixed to this block. For this reason, the pulling rod 2 is easily housed by being tilted like a chain line, and when it is raised as shown by a solid line, the end of the oscillating piece 5 comes into contact with the bearing 3 (main body 1) and is further rotated. Be blocked. That is, the pull rod 2 is fixed in a state where it rises with respect to the anchor main body 1 at a required angle. In this state, the anchor main body 1 bites into the seabed G by being pulled by the line cord a.
[0013]
Next, the traction jig A will be described. As shown in FIGS. 1 to 5, a suspension ring 11 is provided at one end of the cylindrical body 10, and the rope a is fastened to the suspension ring 11. A piston 12 and a spring seat 13 are housed in the cylinder 10 so as to be movable in the cylinder axis direction, and an operating rod 14 passes through the spring seat 13 from the piston 12 toward the other end of the cylinder 10. It extends. A pin 15 is screwed into the receiving seat 13, and the pin 15 is slidably fitted into the long hole 16 of the cylindrical body 10. Further, a tension adjusting nut 17a and a fixing nut 17b are screwed into the outer surface of the cylindrical body 10, and the pin 15 comes into contact with the adjusting nut 17a, thereby preventing further movement of the receiving seat 13. The adjusting nut 17a is fixed by screwing the fixing nut 17b. Both nuts 17 a and 17 b are prevented from coming off by a retaining ring 23.
[0014]
A coil spring 18 is provided between the piston 12 and the receiving seat 13 and biases the piston 12 toward one end of the cylindrical body 10 at the position of the receiving seat 13 determined by the adjusting nut 17a. For this reason, at the adjustment position of the piston 12, the tension to the operating rod 14 acts on the spring 18 and contracts.
[0015]
An engagement block 19 is screwed to the distal end of the operating rod 14, and the block 19 can protrude and retract at the other end of the cylindrical body 10. A locking hole 20 is formed in the block 19, and an engagement element 22 of a locking ring 21 is fitted into the locking hole 20. As shown in FIG. 4, this fitting is usually such that most of the block 19 enters the cylinder 10 and the opening of the locking hole 20 opens to the extent that the engaging element 22 cannot be removed. If the block 19 protrudes from the cylindrical body 10 by the movement of the locking ring 21 and the locking hole 20 opens largely as shown in FIG. 5, the engaging element 22 is pulled out from the opening and released. At this time, the notch 20b through which the flange 22a of the engagement element 22 passes has a width that the engagement element 22 cannot pass through, and the engagement element 22 is pulled out by sliding the engagement element 22 along the inclined surface 20a of the locking hole 20. .
[0016]
This embodiment has the above-described configuration. Next, a method of using the same will be described. First, as shown in FIG. 5, the engagement is within the traction force of the windlass (winches) of the ship S or within the traction force of other means. The position of the seat 13 is determined by turning the adjusting nut 17a so that the coupling 22 is detached from the block 19.
[0017]
Thereafter, as shown in FIGS. 1 to 3, the cable a extending from the ship S is tied to the suspension ring 11 and the locking ring 21 is locked to the pulling bar 2 of the anchor L. Further, the lifting rope b is provided between the base of the anchor L and the suspension ring 11 of the traction jig A with a little margin. In this state, as shown in FIG. 1 and FIG. 2, the anchor L is released into the sea and digs into the sea floor G to perform the anchor action. In FIG. 1, the anchor L and the traction jig A are drawn considerably larger than the ship S.
[0018]
When pulling the anchor L with the winch or the like when pulling up the anchor L, the anchor L usually can overcome the biting force of the anchor L and the anchor L can be separated from the seabed G and collected.
[0019]
However, if the anchor main body 1 bites into the rock in a rocky place and the anchor main body 1 does not come out of the seabed G by the pulling force via the pulling rod 2, the pulling jig A starts from FIG. As shown in FIG. 5, the piston 12 moves against the spring 18 by the attractive force, the block 19 protrudes from the cylindrical body 10, and the engagement hole 20 is eventually opened. As shown in FIG. The puller 22 is separated from the block 19 and the pulling jig A and the pulling rod 2 are separated.
[0020]
Then, the pulling force of the whirling cord a moves to the pulling cord b, and as shown by the chain line in FIG. 2, the pulling force acts on the root of the anchor main body 1. L is collected.
[0021]
Contrary to the above-described embodiment, the same effect can be obtained by connecting the suspension ring 11 to the pulling hook 2 side and the locking ring 21 to the winding line a side.
[0022]
【The invention's effect】
The present invention is configured as described above, and when it is moored, it does not release the lock with the puller, and when the anchor is lifted, it can be reliably pulled from the root side. The anchor can be easily lifted even in a rocky place.
