JPH08150986A - Emergency towing device of large oil tanker - Google Patents

Abstract

PURPOSE: To provide a device to facilitate towing work in case of emergency by a fire wire (a towline) and a fire wire reel used in the case of towing a tanker by a tugboat. CONSTITUTION: A small diameter wire 1, a chain 3 and a large diameter wire 4 are joined together in this order, and a stopper 6 is fixed to a deck 5 of a ship. A bolt 7 of the stopper 6 is dropped in a recess 9 of a bolt receiver 8, and this bolt 7 is brought into contact with the chain 3, and the chain 3 is fixed to its position.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire wire used when a tanker is towed by a tugboat.
And a fire wire reel that facilitates towing work in an emergency.

[0002]

2. Description of the Related Art Since a conventional fire wire is not required to have a large tugboat capability, its thickness is not so thick and it is not particularly difficult to mount and remove it on a fire wire reel. However, if the law requires 200 tons of tugboat capacity, the wire itself will become thicker, and it will not be easy to attach the fire wire to the fire wire reel or remove it. A device that can be easily attached and detached is required, but a device that easily satisfies such a demand has not yet been developed.

[0003]

SUMMARY OF THE INVENTION The present invention provides a fire wire system which satisfies such requirements and has a tug capability of up to 200 tons, yet is easy to attach to a fire wire reel and does not need to be removed. It is intended to be provided.

[0005]

According to the present invention, one end of a small diameter wire rope can be locked to a fire wire reel, and one end of an intermediate connecting member stronger than the small diameter wire rope is attached to the small diameter wire rope. A fire wire characterized in that it is connected to the other end of the connecting member, and a wire rope having a large diameter is connected to the connecting member, and the stopper of the intermediate connecting member provided on the hull can be locked to the connecting member. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view showing an example of the present invention, in which a thin wire 1 is formed with a thimble 2 at one end thereof so that it can be engaged with a fire wire ring (not shown) and the other end is intermediate. It is connected to the chain 3 which is a connecting member. The other end of the chain 3 is connected to a wire 4 having a large diameter, and a stopper 6 is attached to a deck 5 of a ship which is tow a tanker (not shown) by the wire 4 having a large diameter. The chain 7 of the stopper 6 is fixed, and the chain 7 is dropped into the recess 9 of the frame receiver 8, and the chain 7 is brought into contact with the chain 3 to fix the position of the chain.

FIG. 2 is a perspective view showing the state of engagement between the stopper 6 and the chain. The stopper 6 is provided with a hook receiver 8 on both left and right sides, and a hook 7 which moves up and down by a hinge 10 is provided in a recess 9 of the hook receiver. When it falls, Kannuki 7 comes into contact with the chain 3 to stop the chain. The stopper 6 is not limited to the above-mentioned stopper type but may be of any type such as a compression type or a bonnet type.

[0008]

EFFECTS OF THE INVENTION The fire wire of the present invention can be easily locked to the fire wire reel because the end portion of the fire wire is a thin wire although the fire wire is towed using a large diameter wire. Moreover, since a chain is interposed between the large-diameter wire and the small-diameter wire, and the chain is fixed to the deck by the stopper, the large force of the tugboat is not transmitted to the small-diameter wire, so the wire may be broken. Absent. When the wire is wound up, the chain can be wound up smoothly by engaging the chain with the stopper.
