Effects of the invention

The effects of the endless winch of the present invention will be described.

First, the endless winch according to claim 1 is moved along the groove of the winding drum by rotating the driving shaft of the winch body and rotating the winding drum attached to the driving shaft. Move the rope.

When the moving rope is positioned appropriately by contacting the lower half of the rope with the groove of the winding drum and pressing the upper half by the pressing moving body, the rotational movement of the winding drum is transmitted without waste and can move smoothly.

Due to the tension of the moving rope, the moving rope is twisted and the lower half of the twisted part is separated from the groove, so that it is easy to separate from the groove. Since all or some of the rollers are provided with a preventing body, the moving rope can be moved by the preventing body without detaching from the groove.

For this reason, it is possible to move the moving rope continuously without requiring frequent maintenance work as in the prior art.

For this reason, it is possible to prevent detachment independently of the pressing action of the moving rope by the pressing moving body, and the occurrence of trouble during operation of the endless winch is reduced.

Next, in the moving method of the moving rope using the endless winch according to claim 2, the moving rope is wound around the groove of the winding drum and moved while being pressed.

At this time, due to the tension of the moving rope, the moving rope is twisted, and the lower half of the twisted portion is separated from the groove and easily separated from the groove. And since the prevention body is provided in the winding drum, the movement rope can be smoothly moved by the prevention body without being detached from the groove.

As described above, the moving method of the moving rope using the endless winch of the present invention can move smoothly without detaching from the groove regardless of the tension of the moving rope.

Moreover, the structure of the prevention body is simple and does not require frequent maintenance work.

The attachment position of the prevention body can be freely installed, and the removal of the moving rope can be surely prevented by using the prevention body according to the purpose.

Next, the endless winch of the present invention will be described with reference to the drawings.

FIG. 1 is a partially sectional plan view schematically illustrating a first embodiment of an endless winch according to the present invention, and FIG. 2 is a partially sectional side view schematically illustrating a preventer of the endless winch of FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9 and FIG.

An endless winch 1 according to the present invention includes a rectangular winch body 2, a drive shaft 3 rotatably supported on the winch body 2 and driven to rotate by a drive source (not shown), and the drive shaft 3 A circular winding drum 4 attached to the winding drum, a groove 5 having a substantially V-shaped cross section formed along the outer peripheral edge of the winding drum 4, and a moving rope 10 wound around the groove 5 It is comprised from the press moving body 7 stretched | stretched by the elastic body 6 provided along the taking-out side from the side and connected to the both ends.

The pressing moving body 7 is formed by connecting a plurality of rollers 8 rotatably supported on a rotating shaft 8A via a connecting plate 8B, and on both sides 8C side of each roller 8, the grooves 5 are formed. A preventer 9 that is formed in a disk shape and extends outward on the drive shaft 3 side is rotatably supported on the rotary shaft 8A.

Thereby, since the said prevention body 9 rotates separately with the roller 8, the pressing of the movement rope 10 to the groove | channel 5 side by the roller 8 and the removal prevention from the groove | channel 5 of the movement rope 10 of the prevention body 9 are prevented. Each can be done independently.

That is, separation from the groove 5 portion where the lower half of the moving rope 10 is located is pressed by the roller 8 by pressing the upper half of the moving rope 10 and the shift of the moving rope 10 in the left-right direction is prevented 9. Can be prevented.

The configuration of the endless winch 1 according to the present invention is configured as described above. Next, the case where the moving rope 10 is moved using the endless winch 1 will be described.

First, a moving rope 10 connected to a net or the like (net or sheet) is wound along a groove 5 of a winding drum 4 attached to the drive shaft 3 of the winch body 2, and the drive shaft 3 is rotationally driven by a drive source. Then, the winding drum 4 is rotated.

Further, the pressing moving body 7 is in a state where both ends thereof are stretched by the elastic body 6 while being pulled in the rotating direction of the winding drum 4.

At this time, the moving rope 10 in which the groove 5 is located has the lower half installed in the groove 5, the upper half protrudes from the groove 5, and the protruding upper half is moved to the groove 5 side by the roller 8 forming the pressing moving body 7. It becomes a pressed state, and can move reliably along the rotation of the winding drum 4 without waste.

However, since the moving rope 10 is connected to a net or the like, the moving rope 10 is connected to the moving rope 10 due to the difference in tension between the take-in side and the take-out side of the move rope 10 with respect to the winding drum 4. Slack, deflection, and twist are likely to occur. For example, the twisted portion of the moving rope 10 is not properly installed in the groove 5 (the lower half of the moving rope 10 is separated from the groove 5). The roller 8 portion is sequentially lifted above the groove 5. As a result, the roller 8 cannot be stably pressed toward the groove 5 only by the pressing of the roller 8, and is easily separated from the groove 5. Since the prevention body 9 rotatably supported on the rotary shaft 8 is provided, the movement rope 10 is maintained so as to be wrapped, and the part floating from the groove 5 is also separated from the left and right by the prevention body 9. It is possible to prevent the removal.

Moreover, since the prevention body 9 is rotatably supported by the rotation shaft 8A of the roller 8, it prevents the moving rope 10 located in the groove 5 from coming off in the left-right direction without interlocking with the pressing of the roller 8. Therefore, it is possible to reliably prevent the moving rope 10 from being detached.

Moreover, even if the installation position of the endless winch 1 is an inclined position, the moving rope 10 can move without being detached from the groove 5, and there is an advantage that the installation position is not limited.

Further, even if the moving rope 10 is worn and the cross-sectional shape is deformed, the moving rope 10 is detached from the groove 5 by pressing the roller 8 toward the groove 5 and preventing the prevention body 9 from separating in the left-right direction in the same manner as described above. You can move smoothly without having to.

In the above embodiment, the prevention body 8 is rotatably supported on the rotation shaft 8A of the roller 8 so that the prevention body 8 can rotate independently of the roller 8. However, the prevention body 9 of the present invention is formed in this manner. For example, the roller 8 can be formed integrally with the roller 8 by extending the side surface 8C of the roller 8 to the drive shaft 3 side. In this case, in order to rotate integrally with the roller 8, the pressing to the moving rope 10 and the prevention of detachment can be performed synchronously.

In the above embodiment, the prevention body 9 is attached to both side surfaces of the roller 8. However, in the present invention, the attachment of the prevention body 9 is not limited to this. For example, the groove 5 is opposite to the winch body 2. It is also possible to attach the prevention body 9 only to the above. In this case, formation of the prevention body 9 is easy.

Further, in the above embodiment, the prevention body 9 is provided on all the rollers 8 that form the pressing and moving body 7. However, in the present invention, it is not essential to provide the prevention body 9 on all the rollers 8; It is possible to provide the prevention body 9 only on the roller 8, and it is also possible to provide the prevention body 9 at a desired interval. It can be set freely according to the tension level of the moving rope 10.

Further, in the above embodiment, the prevention body 9 is formed on the side surface of the roller 8, but in the present invention, the formation of the prevention body 9 is not limited to this, and the rotation body 9 is freely rotatable on the drive shaft 3 of the winding drum 4. It is also possible to attach and form a disk-shaped plate body. In this case, the replacement work of the prevention body 9 is easier than in the case where the prevention body 9 is formed on the roller 8.

Further, in the above embodiment, the prevention body 9 is formed on the side surface of the roller 8. However, in the present invention, the formation of the prevention body 9 is not limited to this, and the rotation body 9 is rotatable on the drive shaft 3 of the winding drum 4. In addition, it can be formed by being rotatably attached to the rotating shaft 8A of the roller 8. In particular, by connecting the rollers 8 facing each other with the drive shaft 3 in a straight line with the prevention body 9, it is possible to prevent the movement rope 10 from being detached while assisting the movement of the pressing movement body 7. Of the rollers 8 forming the movable body 7, the roller 8 on both ends and the drive shaft 3 are connected by a substantially V-shaped preventing body 9, so that the moving rope 10 is taken into the groove 5 of the winding drum 4. And the movement of the take-out portion of the moving rope 10 from the groove 5 can be moved smoothly.

In the above embodiment, the number of the grooves 5 of the winding drum 4 is one. However, even in the case of the winding drum 4 in which two or more grooves 5 are formed, the preventive body 9 is used for movement. The detachment of the rope 10 can be prevented.

Furthermore, in the above embodiment, one winding drum 4 is installed, but two or the like are attached to the winch body 2 and each roller 8 that forms the press moving body 7 provided on each winding drum 4 is prevented by each. It is also possible to attach 9.
