[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a guide roller for a main rope, and more specifically, a main rope for connecting a culture basket containing a cultured product such as pearl oyster via a hanging rope is pulled up from the sea to a boat by a lifting device. The present invention relates to a guide roller in which a main rope is suspended along with a pulling device and guided to the sea so as to be returned to the sea continuously after a pulling operation.

[0002]

[Prior art]

 For the cultivation of pearl oysters, the pearl oysters are housed in a cultivating cage C that is connected to each other through suspension measures R ′ while keeping the main ropes R (see FIG. 6) at approximately equal intervals. It is performed by connecting a float F to R and submerging it to a substantially constant depth in the sea. To clean the pearl oyster, as shown schematically in FIG. 5, the main measure R is applied to the pulling device 1 installed on the front side of the boat S on the port side (right side in the figure) and the guide roller 50 provided on the port side rear. While straddling and driving the pulling device 1, the main rope R is sent to the guide roller 50 side, high-pressure water is jetted from the boat S to the aquaculture cage C, and the pulled-up main rope R passes through the guide roller 50. Continuously returned to sea. When the pulling device 1 pulls up the main rope R, the boat S relatively moves forward.

In the conventional guide roller 50, as shown in FIG. 7 and FIG. 8 viewed from the A ′ side, the drum 11 and the disks 12 and 13 whose diameters are expanded on both sides are integrated. It is rotatably supported by a horizontal shaft 14, and the disk 12 is arranged so as to face the sea side B (see FIG. 8).

A main rope receiving portion 11 ′ that receives and passes the main rope R on the drum 11 is defined between the blade plate 12 a on the side of the disk 12 and the blade plate 13 a on the side of the disk 13. . When the main ropes R sent from the pulling device 1 pass through the main rope receiving portion 11 ′ while coming in contact with the vane plates 12a and 13a, respectively, the guide rollers 50 rotate without a drive source such as a motor. . The vane plates 12a and 13a are provided at predetermined angles so as to alternate in the circumferential direction of the drum 11, and the main rope receiving portion 11 is provided so that the main rope R can be reliably received by the main rope receiving portion 11 '. 'Slope to lower height. The vane plate 12a is set higher than the vane plate 13a, and its height extends to the peripheral edge of the disc 12. The slanted side portion of the blade plate 12a is also for smoothly passing the suspension line R '. If the blade plate 12a is not provided with an inclination and is a blade plate which stands upright with respect to the horizontal axis 14, the suspension line R'is provided. Does not pass smoothly. Further, the height of the vane plate 13a is lowered so that the float F can easily pass over the drum 11, and the center of gravity of the float F is moved to the boat S side so that the float F does not pass over the vane plate 12. There is.

Further, in order to pass the hanging rope R ′ and the aquaculture cage C to the guide roller 50, not on the drum 11 but on the sea side B of the disc 12, the hanging rope R ′ is scratched and the main rope R is pulled. The dorsal streak 15 that separates the float F, the round streak 16 and 17 that assists the float F climbing on the drum 11, and the streak 18 that directs the float F that has finished passing through the drum 11 toward the sea side B are circles. Bars are arranged on the sea side B of the plate 12. Further, a recess 12 'is provided in a portion of the peripheral edge of the disk 12 that coincides with the vane 12a, and the hanging rope R'is scratched by the recess 12' and passes through the guide roller 50. ,

[0006]

[Problems to be solved by the device]

 However, in the conventional guide roller 50, the main rope R does not drop off in a gentle wave state such as when there is no wind, but after the main rope R passes the guide roller 50, the main rope R bends toward the sea side B. However, there was a defect that the main rope R was pulled to the sea side B when the wind was strong, and climbed up on the vane plate 12a and fell off to the sea side B of the disk 12. In this case, the main rope R that has fallen out of work must be returned to the drum 11, and if the wind is too strong, the work itself is currently disabled.

The present invention has been made in view of the above problems, and an object thereof is to provide a guide roller for a main rope that can reliably prevent the main rope from falling off.

[0008]

[Means for Solving the Problems]

 The guide roller according to the present invention is, as a means for achieving the above object, the main rope pulled up from the sea to the boat by the pulling device and returned to the sea again after the pulling work. A vertical bar member is attached to a conventional guide roller which has a diameter reduced in between and which is received by a drum which is rotatable integrally with the disc and passed therethrough.

Further, the vertical rod-shaped member is erected close to a side portion on the downstream side of the circular plate in the direction in which the main measure passes. The position of the standing rod-shaped member may be any position as long as it can achieve the purpose of preventing the main measure from falling off, but its limitation is difficult, and at least the main measure has passed the drum and the sea side from the boat side. It is on the downstream side, which changes its direction to, and if the standing bar-shaped member is too far from the disc, it prevents the compact design of the guide roller, so we decided to place it close to the side of the disc.

Further, the standing rod-shaped member has substantially the same height as the disc, which is effective for preventing the main measure from falling off if the height is higher than the height of the disc, but can be connected to the main rope. This is because it is not possible to smoothly ride over the standing bar-shaped member, and if the height is too lower than the height of the disk, it is impossible to prevent the main measure from falling off.

The vertical rod-like member has a horizontal cross section of a circular shape or a shape close to a circular shape, and it is desirable that the diameter thereof is large to some extent. Further, although the upright bar-shaped member is erected vertically, the upright bar-shaped member may be erected vertically rather than vertically. The upright bar-shaped member also includes a bent bar-shaped member.

Further, as a preferable material for the standing rod-shaped member, a reinforcing bar can be mentioned, but the material is not limited to this, and it can be made of a material having a predetermined strength.

In the present invention, the main rope connects the aquaculture cages via the suspension ropes, and the suspension ropes and the aquaculture cages are configured to pass from between the discs. A horizontal rod-shaped member that receives the suspension cord and rides over the vertical rod-shaped member so that the rope is not caught by the vertical rod-shaped member can be extended from the top of the vertical rod-shaped member to the disc side.

The horizontal rod-shaped member is an auxiliary member that extends from the top of the vertical rod-shaped member to receive the hanging rope and to pass over the vertical rod-shaped member.

Further, in the present invention, the upright bar-shaped member may be composed of a shaft member and a pipe member that rotatably surrounds the shaft member. The friction that acts between the main rope and the vertical rod that receives it is reduced by the rotation of the cylindrical member.

Further, if the horizontal bar-shaped member is provided with a projecting portion projecting from the top of the standing rod-shaped member to the downstream side, this projecting portion restricts the upward movement of the main rope along the vertical rod-shaped member. Further, even if the standing rod member is bent toward the disc side, a load can be applied to the upward movement of the main rope along the standing rod member.

[0017]

[Action]

 In the present invention, even if the main measure on the drum is pulled to the sea side by the wave wind and tries to get over the disk, the vertical bar-shaped member interferes and cannot get out of the disk, so the main measure is dropped. Can be prevented.

[0018]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a front view of a guide roller 10 according to the present invention installed on the rear of a boat side as seen from the sea side. The same parts as those of the conventional guide roller 50 described with reference to FIGS. 5 to 7 are designated by the same reference numerals and the description thereof will be omitted.

The guide roller 10 is close to the side portion of the disc 12 coming to the downstream side (left side in the figure) in the passage direction of the main measure R sent from the pulling device in front of the boat side, and the disc. At a position slightly inside of 12 (see FIG. 2), a shaft bar 20 ″ as a tube member and a rotating roller 20 as a tube member that surrounds the shaft bar 20 ″ and rotatable as a vertical bar member are provided substantially vertically. The rotary roller 20 has a height substantially the same as that of the disc 12, and receives the main rope R, which has passed through the drum 11 and turned from the boat side to the sea side B, on the peripheral surface (see FIG. 2). Since the rotating roller 20 rotates by the passage of the main rope R, friction generated between them can be reduced.

Further, a horizontal bar 21 as a horizontal bar member extends in a substantially horizontal direction from the top 21 ′ of the rotary roller 20 or the axial bar 20 ″ toward the disk 12 side, and the horizontal bar 21 is a dodge bar 15. Each of them is fixed by welding to the upper portion of the bar arrangement portion such as the round bars 16 and 17. The lower end of the shaft bar 21 ″ is welded below the bar arrangement portion.

In the guide roller 10 configured as described above, even if the main rope R is pulled to the sea side B by strong wave wind and tries to get over the disk 12 from above the blade plate 12a, the top portion 20 of the rotating roller 20 is It is not possible to get over it until ', and the main rope R will not fall off the guide roller 10.

Further, if only the rotating roller 20 is installed, the hanging rope R ′ passing through the guide roller 10 from the sea side B of the disk 12 through the recess 12 ′ is caught by the roller 20, so that the horizontal stirrup 21 is provided. As a result, it is possible to smoothly pass over the roller 20 by receiving the hanging rope R ′ passing there.

As another embodiment of the present invention, as shown in FIG. 3, a horizontal rib 21b has a protruding portion 21b 'slightly protruding downstream from the top of the rotating roller 20b (schematically shown). In this case, the projecting portion 21b ′ functions as a stopper that restricts the upward movement of the main rope R along the roller 20b, so that the fall prevention effect of the main measure R is further improved.

Further, as shown in FIG. 4, the vertical bar 20c as the vertical bar member may be bent toward the disk 12, and in this case also, the main measure R moves upward along the vertical bar 20c. A load is added to the.

Further, as shown in FIG. 5, it is possible to design so that the horizontal streak 21d continuously inclines from the dodge streak 15 'so that the top of the rotary roller 20d projects downstream.

[0027]

[Effect of device]

 As described above, in the guide roller according to the present invention, since the main measure cannot get over the disks due to the attachment of the standing rod-like member, it is possible to reliably prevent the main measure from falling out between the disks. Even if the wind is strong, the main rope can be pulled up without interruption or suspension.
