Description

Chain stopper {Chain stopper}

The present invention relates to a chain stopper for use in laying a ship and more particularly to a chain stopper configured to suitably operate when a chain unloaded from a ship is lifted up and lifted by a crane, A stopper plate integrally formed with the operation lever in such a structure as to operate to allow the chain flow only in one direction of the chain and to stop the flow of the chain in the opposite direction; A roller formed with a shaft and hinged to the base, and a groove formed along a circumferential center of the roller.

Generally, a chain stopper is used to ship the ship. One end of the chain that comes out of the chain stopper is joined to the ship, and the other end is fixed to the concrete in the land.

1, a chain stopper 30 of the prior art has a stopper plate 35 rotatably coupled to a hinge shaft 32 on a fixed base 31 to hold the chain firmly when the chain is pulled toward the ship. The role prevents the ship from being moved by winds or waves.

Japanese Patent Application Laid-Open No. 10-1338959 discloses a chain stopper in which a stopper plate catches a flow of a chain in one direction, and a chain stopper in which a roller is installed in a block 10-1122304 is known, It is a structure that pulls the chain.

Such a conventional chain stopper is a chain stopper having a structure suitable for lifting and unloading a chain at an oblique angle, and a low-height forklift is used for stacking a loosened chain in one place when a chain is released from a ship.

The way of using forklifts like this is that there is a lot of inconveniences such as forklifts to get the space to put up the forklifts while lifting things piled up on the dockyard, and it takes a lot of time to lift and lift the chain.

Therefore, there has been a demand for an improved technique capable of solving the problems of conventional chain tackle using such a forklift while pulling the chain tied up with the ship faster and more conveniently.

It is an object of the present invention to provide a chain stopper suitable for lifting and mounting a chain to which a ship has been bundled by using a crane.

In order to achieve this object, the present invention relates to a hinge device comprising a base 310 fixed to the floor, a hinge coupled to the base 310 to allow the chain 350 to flow in one direction only, A hinge shaft 322 is formed at a position higher than the height of the hinge shaft 321 of the stopper plate 325 and the stopper plate 325 is formed integrally with the operation lever 326, A roller 330 hinged to the roller 310, and a groove 333 formed along the center of the circumference of the roller 330. [

The present invention also relates to a hinge assembly comprising a base 310 secured to the bottom and hinged to the base 310 to enable the chain 350 to flow only in one direction and to stop the chain flow in the opposite direction A hinge shaft 322 is formed at a position higher than the height of the hinge shaft 321 of the stopper plate 325 so that the hinge shaft 322 is hinge-coupled to the base 310. The stopper plate 325 is formed integrally with the operation lever 326, And a plurality of protrusions 332 formed along the circumference of the roller 330. The chain stopper 330 includes a plurality of protrusions 332 formed along the circumference of the roller 330,

The present invention also relates to a conventional chase topper 30 composed of a stopper plate 35 and an operation lever 36 hinged to a base 31 and a base 31 and a conventional chase topper 30 having a roller 330 hinged by a hinge shaft 322 The hinge shaft 322 of the roller 330 is connected to the stopper plate 35 and the hinge shaft 32 of the operation lever 36 And is formed at a high position.

The chain stopper installed on the concrete floor of the marina is fixed to the bottom of the base 310 and the chain is fixed to the ship through the chain stopper. When the stopper plate 325 is held by the operation lever 326, the chain flow is stopped in the direction of the ship from that time.

When the ship leaves the marina, the chain is pulled up and the chain is pulled up and put in one place. In this embodiment, the chain is lifted up from the upper part by using a crane. To lift the chain by the crane, The position of the roller 330 is formed at a position higher than the stopper plate 325.

It is recommended that there is no cover or other attachment on the edge of the roller so that there is no catch when the crane is pulled from above.

In the present invention, a groove 333 is formed along the center of the circumference of the roller 330 so that the chain can flow smoothly together with the rotation of the roller while preventing the chain from entering into the groove 333.

In addition, the present invention also contemplates that the roller 330 forms a plurality of protrusions 332 along the circumference, instead of forming the grooves 333 in the circumferential portion, such that the protrusions are inserted into the holes of the chain as the rollers rotate, .

In addition, the present invention can utilize a chain stopper installed in the existing chain stopper, hinge-coupled to the base and utilizing a stopper plate integrally formed with the operation lever, The stopper can be replaced by a chain stopper for a crane without removing the stopper.

At this time, the roller is joined / formed such that the height of the roller is higher than that of the stopper plate. If a conventional chain stopper is utilized, it is not costly to remove, and a new chain stopper attached to the roller portion alone can be reduced in cost without having to form a stopper play portion.

The chain stopper of the present invention has a structure suitable for lifting the chain up by forming the rollers higher than that of the chain. When the chain connected to the ship is unrolled, the chain stopper pulls the chain by the crane and lifts it, .

Also, since the present invention uses a crane to lift the chain from a higher position at a higher position and to place it in one place, there is an effect that the conventional forklift can be conveniently positioned without inconvenience of removing objects for entering a forklift .

In addition, since the present invention can utilize the existing chain stoppers, it is possible to reduce the removal cost.
