Description

[Detailed Description of the Invention] The present invention relates to a new proposal for a guide roller device for an anchor.

The present invention is a guide roller device for anchors that facilitates the operation of lifting anchors from boats and fishing boats. The reason is that it can be stopped at any position.

An example of implementing the present invention will be described below based on the drawings.

1 is a front view, FIG. 2 is a rear view, FIG. 3 is a partially cutaway plan view, FIG. 4 is a side sectional view, and FIG. 5 is an explanatory view of the operation.

Reference numerals 1 and 1' are a pair of left and right gate-shaped supports, which are symmetrically set up, and a rotation shaft 3,
3' is pivotally supported, and guide rollers 4, 4' are installed in the upper part.
The claw cams 5, 5' are eccentrically and rotatably mounted on the lower part. The guide rollers 4, 4' are formed with a taper P that widens downward, and when the anchor rope is inserted through the upper opening m during the hoisting operation described below, the guide rollers 4, 4' It is designed to be guided by the rotation of '. On the other hand, the claw cams 5 and 5' are elliptical (see Figure 3).
A serrated blade e is formed on the opposing inner surface on the side where the anchor rope is pulled, and a protrusion f is formed on the side opposite to the serrated blade e. The protrusion f is connected to each support column 1, 1' during the operation described later.
The claw cam 5 engages with the protruding flange g formed on the base.
This is to limit the rotation of 5' beyond a certain angle.

On the other hand, 6 is a horizontal roller provided on the anti-serrated blade side of the claw cams 5, 5' on approximately the same plane as the claw cams 5, 5', and 7 is a set screw hole drilled in the base 2. .

Next, the use of the device of the present invention will be explained. The horizontal roller 6 is attached to a port or the bow or side of a fishing boat so as to protrude toward the sea.
Therefore, when actually using an anchor, the anchor is dropped into the sea along with the wrapped rope.Then, in order to pull up the anchor, part of the rope 8 is attached to the portal supports 1, 1'. It is guided between the guide rollers 4, 4' from the upper opening m and taken up through the guide rollers 4, 4', and the frictional resistance is reduced by the freely rotating horizontal roller 6 and the guide rollers 4, 4'. This allows for smooth collection by reducing the amount of waste. If the rope 8 is to be temporarily rested while being picked up, the rope 8 is directed toward the claw cams 5, 5' and pulled down a little so that it is approximately in the same plane as the horizontal roller 6 in the illustrated example. As a result, the rope 8 is caught between the claw cams 5 and 5', and at the same time as the rope 8 is loosened, the claw cams 5 and 5' rotate so that the distance between them narrows, and the rope 8 is cut with the serrated blade e. Since it locks in the bitten state, it can be stopped reliably without slipping. On the other hand, if you want to pull it up again, by pulling the rope 8 toward you in that state, the claw cams 5 and 5' that were holding the rope 8 will rotate outward in the opposite direction. The locked state will be released, and the rope 8 can be taken up as it is, but it will be done very smoothly by lifting the rope 8 slightly upward and bringing it into contact with the guide rollers 4, 4'. It will be possible to pick it up.

The device of the present invention can be stopped at any point during the hoisting operation, compared to conventional manual operations or devices that simply pull the hoist up via guide rollers. To make it possible to carry out anchor lifting work at a deep position easily and without pain.

Claims (1)

[Scope of utility model registration request] Each rotating shaft is pivotally supported between a pair of left and right gate-shaped columns and a bottom stand, and a guide roller is attached to the upper part and a claw cam is attached to the lower part so that they can rotate freely in an eccentric state.
It is characterized by having serrated blades partially engraved on the opposite surface which is the side from which the anchor rope is taken, and a horizontal roller is provided on the side from which the anchor rope is paid out on approximately the same plane as the claw cam.
