Description
Technical Field
The invention relates to the field of ships, in particular to a fracture-preventing ship anchor structure for a ship and a using method thereof.
Background
The anchor of the ship is one of the important parts of the ship, and comprises an anchor chain and an anchor fluke body, wherein the anchor fluke body is fixed on the ship through the anchor chain, when the ship is ready to berth, the anchor chain and the anchor fluke body are thrown out by an anchor machine, under the action of gravity, an anchor fluke of the anchor fluke body is inserted into the water bottom, and the generated holding power is consolidated with the water bottom, so that the ship is firmly moored at a preset position.
However, since there are various water bottom conditions and reefs and rocks of various sizes, if the water area to be anchored is not probed in advance during anchoring, or the anchoring area itself is in a water area with many reefs, the fluke of the fluke body is easily stuck in the rock gap during use, so that the fluke cannot be smoothly retracted during anchoring, and the phenomena of overexertion and even breakage occur, thereby causing huge property loss and even causing marine accidents.
The Chinese patent No. CN201720021851.3 discloses an anti-fracture anchor, which reduces stress at an ear plate fulcrum by changing the position of the ear plate fulcrum, thereby preventing anchor flukes from fracturing and prolonging the service life of the anchor. However, the mode only improves the anti-fracture strength of the ship anchor to a certain extent, and cannot solve the fracture condition caused by overlarge tension of the anchor chain when the fluke is stuck in a rock gap.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide a fracture-preventing ship anchor structure for a ship and a use method thereof, which solve the problems of fracture and the like caused by incapability of smoothly anchoring when a ship anchor is used and clamped into a rock gap and the like.
The technical scheme is as follows: the invention provides a fracture-preventing ship anchor structure for a ship, which comprises an anchor fluke main body, an anchor rod, a first joint, a first auxiliary anchor chain structure, a main anchor chain structure, a second auxiliary anchor chain structure and a second joint, wherein one end of the anchor rod is fixed on the anchor fluke main body through a rotating shaft and is close to the anchor fluke; the first joint comprises a first chain buckle, a first connecting shaft and a first split pin, and the first connecting shaft is arranged on the first chain buckle and fixed through the first split pin; the first connecting shaft is provided with a fixing hole, the fixing hole side plate is provided with an opening, and the width of the opening is smaller than the diameter of the fixing hole.
In the structure, the application method of the anti-fracture ship anchor structure for the ship comprises the following specific application steps:
s1, when a ship is berthed, a worker operates an anchor machine to throw down a ship anchor to the water bottom, an anchor fluke on an anchor fluke main body is inserted into the water bottom along with forward movement of the ship, so that the ship is fixed, at the moment, a main anchor chain structure and a first auxiliary anchor chain structure are straightened, and a second auxiliary anchor chain structure is in a loose state;
s2, when a ship starts to sail, rolling up a main anchor chain structure, moving the ship backwards, when an anchor fluke of an anchor fluke main body is clamped in a reef gap or cannot be directly pulled up due to other reasons, continuously stressing the end part of a first auxiliary anchor chain structure until the first auxiliary anchor chain structure falls off from an opening of a fixing hole in a first connecting shaft of a first connector, straightening the main anchor chain structure and a second auxiliary anchor chain structure, and moving the second auxiliary anchor chain structure towards a second connector through the stress of the anchor fluke main body connected with the second connector so as to be pulled out from the water bottom;
and S3, rolling the pulled-out fluke main body onto the ship along with the main anchor chain structure, and reinstalling the end part of the first auxiliary anchor chain structure onto the first joint so as to be convenient for use in next mooring.
This ship anchor adopts two supplementary hawse settings, compare in original ship anchor, not only easy operation is convenient, go into in the rock gap or other reasons lead to unable anchor in the ship anchor card moreover, through the automatic chain that takes off of first supplementary hawse structure, make the fluke main part can be under the pulling force of the supplementary hawse structure of second, from the afterbody anchor, thereby make the fluke can easily pull out from environment such as gap, this greatly reduced the cracked condition of hawse structure take place, thereby greatly reduced the loss.
Preferably, the length of the second auxiliary chain structure and the length of the first auxiliary chain structure are in a relation as follows:
l1: a length of the first auxiliary hawse link structure;
l2: a length of the second auxiliary hawse structure;
l3: total length of the first joint and the anchor rod in a straightened state;
a: the angle between the anchor rod and the fluke of the fluke body is a =40 to 45 degrees.
If the second auxiliary anchor chain structure is too short, when the anchor fluke main body is fixed to the water bottom, the main anchor chain structure cannot be straightened with the first auxiliary anchor chain structure and can only be straightened with the second auxiliary anchor chain structure, so that the anchor fluke cannot go deep into the river bottom, and anchor walking is caused; if the second auxiliary anchor chain structure is too long, the second auxiliary anchor chain structure is easy to wind with the fluke in the anchoring process, and therefore the anchoring work is influenced.
Further, a mounting hole is formed in the first fixing seat of the first buckle, and a limiting groove is formed in the side wall of the mounting hole; the second fixing seat of the first chain buckle is provided with a conical mounting hole, and the aperture of the conical mounting hole is gradually reduced from the position close to the mounting hole to the outer side. As a preferable scheme of the invention, the mounting hole on the first fixing seat of the first fastener and the conical mounting hole on the second fixing seat are used for fixing the first connecting shaft.
