Abstract

Disclosed is an anchoring arrangement, an installation method therefor, and a ship. The anchoring arrangement comprises a hawse pipe (1), wherein the hawse pipe (1) obliquely extends to a side of a ship body from a deck face of the ship body, and the hawse pipe (1) is obliquely arranged downward from the bow to the stern of the ship body. The axes of the hawse pipe (1) and a windlass (3) are arranged towards the stern of the ship, and the hawse pipe (1) is obliquely arranged downward, thereby reducing an internal space of the bow occupied by the hawse pipe (1) and preventing that, during the traveling of the ship, seawater lashes the hawse pipe (1) and rushes onto the deck face through the hawse pipe (1).

Description

Mooring device, installation method and ship

Technical field

The invention relates to the technical field of ships, in particular to a mooring device, a mounting method and a ship.

Background technique

When the ship is parked, it is necessary to throw the anchor into the bottom of the water so that the ship can stop. At present, the installation position of the anchor chain of the ship is set to be inclined downward by about 45° from the deck surface of the ship toward the crotch of the ship and then extended to the outside of the ship. However, due to the narrowing of the line shape of the ship's crotch, the internal space of the ship's raft is relatively small. If the chain of the ship is extended to the bow, the inner space of the ship's raft will be occupied, resulting in a narrower space of the stern, which is not conducive to the ship. The arrangement of various equipments, while the anchor chain is arranged in the direction of the bow, the anchor chain and the anchor are vulnerable to the impact of the waves, which may cause the seawater to rush onto the deck of the ship through the anchor chain, and the anchor will still be in the stowed state. The contact of seawater causes the seawater to corrode the anchor and seriously endangers the anchoring safety of the ship.

Summary of the invention

It is an object of the present invention to provide a mooring apparatus that reduces the space occupied by the bow and reduces the flushing of seawater from the anchor chain to the deck.

Another object of the present invention is to provide a method of installing a mooring device, in which the mooring device can reduce the space occupation of the bow and reduce the seawater from the anchor chain to the deck.

Detailed ways

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , in the figure, the direction A is the bow direction and the B direction is the bow direction. In the embodiment, a mooring device according to the present invention includes an anchor chain barrel 1 , and the anchor chain barrel 1 The deck surface of the hull extends obliquely to the side of the hull, and the anchor chain barrel 1 is disposed obliquely downward from the crotch portion of the hull toward the crotch portion.

By passing the anchor chain barrel 1 through the deck of the hull to the side of the hull, and the anchor chain barrel 1 is disposed obliquely downward from the crotch portion of the hull toward the crotch portion, the anchor chain barrel 1 can be prevented from setting a position where the bow space is small. Reduce the occupation of the interior space of the ship's raft, and the structure distribution is more reasonable. At the same time, the orientation of the anchor chain barrel 1 is directed from the crotch portion of the hull toward the crotch portion, so as to prevent the seawater from directly hitting the deck surface of the hull along the anchor chain barrel 1 during the running of the hull. Reduce the seawater erosion of anchors and anchor chains after being stowed, enhance the service life of anchors and anchor chains, and prevent the safety problems caused by corrosion of anchor chains.

Preferably, the angle α between the projection of the anchor chain barrel 1 on the deck and the 舯 axis 2 of the hull is 120° to 150°.

The angle α between the projection of the anchor chain barrel 1 on the deck and the 舯 axis 2 of the hull is 120° to 150°, which ensures that the chain barrel 1 faces the bow of the ship, and ensures that the seawater cannot be removed from the chain barrel 1 The anchor chain 1 that is rushed to the deck and oriented toward the bow can reduce the space occupation of the bow, avoiding the installation of various components and devices in the bow, making the space of the bow relatively crowded and facilitating the construction of the ship.

Further, the angle between the projection of the anchor chain on the deck and the axis of the hull of the hull is preferably 135°.

Preferably, the angle between the anchor chain barrel 1 and the deck surface is 15° to 45°.

The angle between the anchor chain barrel 1 and the deck surface allows the water on the deck to flow into the sea along the anchor chain barrel 1 to avoid corrosion of the anchor chain caused by water accumulation, and at the same time facilitate the retraction of the anchor chain.

In a specific embodiment of the present invention, the angle between the projection of the anchor chain barrel 1 on the deck and the 舯 axis 2 of the hull is 135°, and the angle between the anchor chain barrel 1 and the deck surface is 30°.

Preferably, it further comprises a windlass 3 disposed on the deck surface of the hull, the axis of the windlass 3 being in the same plane as the axis of the anchor chain barrel 1.

The anchoring machine 3 and the axis of the anchor chain barrel 1 are on the same plane, which can prevent the anchor chain from being bent during use, enhance the service life of the anchor chain, and can be applied to the anchoring machine 3 when the chain is retracted. The power is transmitted to the anchor chain to reduce the load on the anchor machine 3 and protect the anchor machine 3.

Preferably, a chain stopper 4 is disposed between the anchoring machine 3 and the anchor chain barrel 1 , and a side of the anchoring machine 3 remote from the anchor chain barrel 1 is correspondingly provided with an anchor chain compartment for storing the anchor chain 5.

The setting of the chain stopper 4 can assist in fixing the anchor chain, preventing the chain from slipping out, and the grip force generated by the anchor and the anchor chain. It is directly transmitted to the hull, and at the same time, it can bear the gravity and inertia force of the anchor during navigation to reduce the load of the windlass 3 and protect the windlass 3.

Preferably, the anchor chain barrel 1 extends outside the side of the side such that an end of the anchor chain barrel 1 adjacent to the side of the side has a sufficient distance from the side of the side and is adjacent to the chain barrel 1 One end of the side of the side is provided with an anchor lip for reinforcing the structural strength of the anchor chain barrel 1.

By extending the chain barrel 1 to the outboard side, there is sufficient distance between the anchor and the hull plate when anchoring or anchoring to prevent the anchor from colliding with the hull plate.

The invention also provides a method for installing a mooring device, comprising the following steps:

S10, determining the arrangement position of the windlass 3 on the deck surface of the ship according to the outer plate line type of the ship's crotch, requiring an angle between the axis of the windlass and the axis of the ship to be between 120 ° and 150 °;

S40, welding and fixing the anchor chain barrel 1.

Specifically, S10 further includes scribing on the deck surface of the ship to determine the arrangement position and orientation of the anchor machine 3.

S30 further includes determining the opening position of the chain chain hole of the anchor chain barrel 1 on the deck surface of the ship according to the setting of the anchoring machine 3, and making a cutting mark to cut the opening of the deck of the ship; The opening position of the side chain hole is determined according to the installation angle of the anchor chain barrel 1, and the opening of the side outer plate is marked.
