Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anchor hoisting device for a ship.

Conventionally, on large ships, pulling up the anchor is done using power, but on small ships, when pulling up the anchor once it has been lowered, it is done manually by pulling up the anchor rope. There is. This required a great deal of effort and time.

In this invention, an anchor lifting device for a ship can quickly and easily pull up an anchor by using the propulsion force generated by the ship's running and the buoyancy of the float body without requiring a power device for pulling up the anchor. We aim to provide the following.

Embodiments of the present invention will be described in detail below based on the drawings.

A is an anchor lifting device, B is a ship, C is an anchor, and D is an anchor rope.

1 is a board consisting of a flat and elongated plate, the tip of which is provided with a serrated rope locking part 2;
A connecting portion 4 for connecting the float body 3 is provided at the base end. In addition, a shackle 6 is pivotally supported at a position close to the rope locking part 2 of the base plate 1 via a removable pin 5, and when the rope locking part 2 is overlapped with the shackle 6, Rope inserter 6
A space smaller than the space through which the anchor rope D is inserted is formed. Moreover, the board 1 is cut out on both sides near the rope locking body 2 on one end thereof,
The shackle 6 is pivotally supported in this notch, and when the board 1 is placed in an upright position, the shackle 6 does not rotate and overlaps the rope locking part 2, and the shackle 6 is fixed in this state. .

Note that 6-1 indicates the eyeballs at the upper left and right ends of the shell 6.

The embodiment of the present invention is constructed as described above, and its operation is as follows.

That is, when pulling up the anchor C, the anchor rope D is inserted into the shackle 6 of the anchor hoisting device A by the necessary means, and the anchor hoisting device A, together with the float body 3 connected to the connecting part 4, is placed on the sea. Throw it to.

The anchor lifting device A thrown on the sea is held at one place on the sea by the float body 3, and in this state, one end of the anchor rope D is fixed to the ship B and the ship B travels.

The anchor rope D is pulled in the direction of the ship's movement by the propulsion force of the ship B, sliding on the shackle 6 connected to the base plate 1, and the base plate 1 is pulled in the sea by the buoyancy of the float body 3 connected to the connecting part 4. Since it is stationary at a certain location, the anchor rope D will pull up the anchor C via the board 1 which is in the same position, and furthermore, the direction in which the anchor rope D is pulled by the ship depends on the shackle of the board 1. 6, the rope locking portion 2 is in the direction in which it does not lock the anchor rope D, so the anchor rope D
slides in the shackle 6 without any hindrance and pulls up the anchor C close to the substrate 1.

To explain this state in more detail, when the anchor rope D is pulled by the propulsion force of the ship B, the rope is pulled in the horizontal direction, so the board 1 becomes almost horizontal, and the ship's side rail of the anchor rope D There will be no hindrance to movement. Furthermore, since the substrate 1 is formed of a flat and elongated plate, the anchor rope D
When pulling the anchor rope D, the upright board 1 rotates from the pivot part of the shaft 6 due to water resistance and becomes horizontal, and the anchor rope D is pulled by the rope locking part 2.
The lock is released easily and smoothly.

Moreover, since the substrate 1 in the horizontal state reduces water resistance, the work of pulling up the anchor rope D to the ship can be carried out smoothly and quickly without requiring any effort.

As described above, if the ship stops pulling the anchor rope D at the same time as the anchor C is pulled upward, the weight of the anchor C will cause the board 1, which is in a nearly horizontal state, to stand up vertically, and the rope will not be attached. Since the stop part 2 is maintained in an upright state by the buoyancy of the float body 3, the anchor rope D is held down between the shaft 6 and the rope stop part 2, and the anchor rope D is held in a locked state.
The substrate 1 is fixed to the floating body 3.
Anchor C is prevented from sinking because it is supported by the buoyancy of C.

In this state, if the anchor rope D is pulled from above the vessel B and the floating anchor C is pulled up onto the vessel B, the work of pulling the anchor is completed.

According to this invention, the anchor is pulled up by the anchor rope by the propulsive force of the ship, and when the anchor rises to a certain depth, the sliding of the anchor rope is stopped, and the base plate integrated with the float body is pulled up. The anchor is integrally fixed to the rope, preventing the anchor from sinking, and has the effect of allowing the anchor to be pulled up easily and in a short time using the ship's propulsion force. Furthermore, the base plate is rotated from the pivot point of the shaft by the propulsion force of the ship and placed in a horizontal position, making it easy to release the anchor rope and reducing water resistance with the base plate in the horizontal position. It can be made small and has the effect of making it possible to pull up the anchor smoothly and quickly.

In addition, since the anchor raising device is composed of a substrate made of a flat and elongated plate and a shaft, it is easy to manufacture, and by using commercially available products, it can be manufactured at low cost. has.
