Abstract

PURPOSE:To lighten the whole structure and simplify a hook removing operation by providing the center of a hook revolving shaft on the extension of the center line of a tug line, providing a hook on the opposite side to the draw-out side of a tug line, and providing a revolving shaft operating ratchet device. CONSTITUTION:A top plate 3 and a rope guide 6 are provided on a housing 2 on a hull fixing base 1, and a revolving shaft 7 is provided on the center part of the housing 2 while a hook 11 is provided on the upper revolving plate 10 of the revolving shaft 7. The hook 11 is fixedly installed on a line joining the center line of a tug line 18 to the center line of the revolving plate 10, and on the opposite side to the pull-out side of the tug line 18 from the center of the revolving plate 10. The revolving shaft 7 is rotated in one direction through a handle 15 by means of a ratchet mechanism 14. A stopper pin 16 and a lever 17 for operating the stopper pin are provided on the bottom face of the revolving plate 10. The hook 11 is not subjected to the turning force due to the tensile force of the tug line, enabling the whole structure to be lightened and simplifying a hook removing operation by means of the operation of a handle.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tug line hook device for ships and marine structures.

[Conventional technology]

Conventionally, in horizontally rotating tag line hook devices,
If the hook is fixed to the rotation axis eccentrically from the line connecting the rotation axis center and the tag line center line, and the tag line is removed, the hook will automatically rotate due to the tension of the tag line when the rotation stopper bin is removed. The tag line was removed.

[Problem that the invention seeks to solve]

In such conventional tag line hook devices, when the frictional force between the pivot shaft and its bearing increases due to aging, or when the tension of the tag line is insufficient, the hook becomes difficult to pivot. Taglines may not be automatically removed. In such a case, it is necessary to turn the hook by one person, but it is necessary to use considerable force in order to release the hook rotation lock and rotate the hook with some tension on the tag line. This is both a demanding and dangerous task. Furthermore, the swing stopper is subject to the swing breakage of the swing shaft due to the tension of the tag line, and there is a problem in that it needs to have a fairly heavy structure.

[Means for solving all the points between τ]

For this reason, the present invention provides a tag line hook device that includes:
A ratchet device having the center of the pivot axis of the hook and the center of the hook on the same extension line as the center line of the tag line, and provided to forcibly rotate the pivot axis, and the ratchet device f
With a swivel handle to operate? It is characterized by the fact that it is equipped with

[Effect]

With the above configuration, the swivel handle makes hooking easier?
You can turn around and release the tag line.

〔Example〕

A tag line hook device as an embodiment of the present invention will be explained with reference to the following nine drawings. Fig. 1 is a plan view thereof;
FIG. 2 is a sectional view taken along the line ■-■ in FIG. 1.

In Figure 1.2, 18 is a tag line, 1 is a stand usually fixed to the hull, 2 is a hollow housing fixed to the top of the stand 1, and 3 is a top plate installed around the top of the housing 2. 1, 1 is a lip that is fixed to the housing 2 and the three top plates 1; 5 is a roughly shaped guide plate whose one end is fixed to the top plate 3 and has a rope guide 6 at the other end; 7 is a hollow part of the housing 2; 8 and 9 are bearings provided between the housing 2 and the rotating shaft 7, 10 is a rotating plate fixed to the upper part of the rotating shaft 7, and 11 is fixed to the upper part of the rotating plate. hook, 12 is pivot axis 7? housing 2

14 is a ratchet device such as a ratchet box spanner that is provided at the lower end of the pivot shaft 7 and rotates the pivot shaft 7 only in one direction; 15 is a pivot handle for the ratchet box spanner 14;

16 is a stopper pin for fixing the rotating plate 10'f, 1
7 is a stopper lever for fitting and removing the stopper pin 16 from the rotating plate 10. Note that the hook 11 is fixed to the upper part of the rotating plate 10 on a line connecting the center line of the tag line 18 and the center line of the rotating plate 10 and on the opposite side of the center of the rotating plate 10 to the drawer of the tag line 18. . Also, 19

The rotating plate 10 and the French hook 11 gradually rotate in the same direction, and the tag line 1 hooked on the hook 11
8 leaves.

〔Effect of the invention〕

As detailed above, in the tag line hook device of the present invention, the centers of the tag line, pivot axis, and hook are on a straight line, so the shape can be almost symmetrical, making it easy to design the amount. It is. In addition, since the hook is not subject to the turning force caused by the tension of the tag line, the stopper pin and stopper lever can be made into lightweight structures. The line will definitely come off. Furthermore, since the ratchet device uses a commonly known and commercially available ratchet box spanner, it can be easily replaced in the event of a failure.
