Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a raw eye splice direction control method.

After tying a messenger rope to the eye splice of the tug rope and winding this messenger rope with a messenger winch to pull up the tag rope, when applying the locking device to the eye splice, the ice Price is facing any direction.

Therefore, for example, if the eye splice is oriented vertically, the locking action by the locking layer cannot be performed, and the orientation must be changed manually. However, in this case, since the eye splice is under tension, it is not easy to manually change the orientation, which may also lead to personal injury. The present invention provides a simple eye splice direction control method capable of solving the problem of consignment, and one embodiment thereof will be described below with reference to the drawings.

1 indicates the main ship and 2 indicates the tugboat.

3 is a tug rope, and the ship 1 is attached to the ice splice 3A.
A gear rope 5 from a side gear winch 4 is tied.

A mooring hardware 6 and a locking device 7 are provided on the ship 1 side, and an eye splice direction control device 8 is provided between these 6 and 7. That is, the eye splice direction control device 8 includes a first bar 9 located on the mooring hardware 6 side and a second bar 10 located on the locking device 7 side. Said first bar
9 is composed of a vertical punch part 9A and a 45-degree inclined village part 98, and the second bar 10 is composed of a vertical punch part 10A and a horizontal punch part 10.
It consists of B. The locking device 7 includes a pair of left and right side plates 11 and a pair of both side plates 1 on the messenger winch 4 side.
1, an L-shaped arm 13 swingably mounted via a shaft 12 between the two, a pulley 15 mounted in the upper recess 14 of the L-shaped arm 13, and a pulley 15 formed at the lower bent portion of the L-shaped arm 13. A receiving part 16 whose upper and front surfaces are open, and a base end that can be detached from the receiving part 16 and which is attached to the machine shaft 12.
Locking hook lifting lever 1 swingably attached to
7, a roller 18 attached to the two-pronged end of the locking hook pull-up lever 17, and a locking hook attached via a horizontal pin 19 between both side plates 11 to allow the two-pronged portion to be removed. A hook 20, a trigger 22 that is attached to the two proximal portions via a horizontal pin 21 and that is removable to the rear end of the locking hook 20, and a spring 23 that biases the trigger 22 into engagement. It consists of a stopper 24 that restricts the amount of swing in the direction, a stopper 25 that restricts the lowering limit of detachment of the locking hook 20, and a stopper 26 that restricts the upper limit of the L-shaped arm 13. The recess 14 and the pulley 15
This forms a guide portion that allows the passage of the messenger rope 5 but prevents the passage of the eye splice 3A. The oblique punch portion 9B of the first bar 9 is inclined at 45 degrees with respect to the rotation axis along a plane parallel to a vertical plane including the rotation axis 0 of the locking hook 20, and The horizontal punch portion 10B of the second bar 10 is parallel to the rotation axis 0 of the locking hook 20. The eye splice 3A of the tug rope 3 tied to the messenger rope 5 is pulled up by winding the messenger rope 5 with the messenger winch 4, and is moved from the mooring hardware 6 to the eye splice direction control device 8.

The direction of the eye splice 3A passing through the mooring hardware 6 differs depending on the direction, such as vertical, horizontal, or diagonal. Note that the direction of the eye splice 3A refers to the orientation of the surface formed by the annular eye splice 3A. However, when passing through the first bar 9, as shown in FIG. 2, it is forcibly guided by a 45-degree oblique angle portion 98, so that the direction is controlled in the 45-degree direction. Next, the eye splice 3A oriented at 45 degrees is forcibly guided by the horizontal punch portion 10B of the second bar 10 and its direction is controlled horizontally. While the tug rope 3 is being pulled up, the L-shaped arm 13 swings forward significantly, and the trigger 22 is released from the locking hook 20, causing the locking device 7 to lock as shown in FIG. Although the stop hook lifting lever 17 is separated upward from the receiving portion 16, the lever 17 is moved as a whole, and accordingly, the stop hook 20' is moved downward until it abuts against the stopper 25. In this position, the messenger rope 5 to be wound up passes through the recess 14 and is guided by the pulley 15'. As the tug rope 3 is pulled up, the eye splice 3A, which cannot pass through the recess 14, engages with the upper end of the L-shaped arm 13, thereby causing the L-shaped arm 13 to wrap around the machine shaft 12 as a pulling force. In the initial stage, only the L-shaped arm 13 is raised upward, but in the middle of the process, the L-shaped arm 13 is raised against the base end of the locking hook lifting lever 17.
The receiving portion 16 of
becomes integral. Therefore, after that, the locking hook lifting lever 17 will also move upward around the machine shaft 12. The upper locking hook lifting lever 17 moves the locking hook 20 upwardly around the horizontal pin 19 via the roller 18, so that the locking hook 2 is lifted up as shown in FIG.
0 into the ice splice 3A. At this time, the trigger 22 automatically engages with the rear end of the locking hook 20, and the locking hook 20, trigger 22, and locking hook lifting lever 17 are integrated. The tug rope 3 is pulled up until the L-shaped arm 13 hits the stopper 26, and then the messenger winch 4 is reversely operated to let out the messenger rope 5. This causes the L-shaped arm 13 to move forward, but the locking hook 20', which is integrated with the locking hook lifting lever 17, remains in place, thus allowing the eye splice 3A to be loosened.
will be locked to the locking hook 20. In order to remove the sub-clamp hook 20 from the eye splice 3A, the trigger 22 may be moved backward against the force of the spring 23. As described above, according to the present invention, when pulling up the tag rope, the direction of the eye splice can be forcibly and automatically controlled using the pulling force, and when facing the locking device, the direction of the eye splice can always be controlled automatically. The horizontal direction can be controlled and the locking device can reliably lock the locking device. This also eliminates the need for manual orientation changes, which can greatly reduce accidents resulting in injury or death.
