Description

Apparatus for tilting mast < RTI ID = 0.0 >

The present invention relates to a mast, and more particularly, to a mast tilting apparatus capable of laying down and standing a mast.

Generally, the ship includes a mast where equipment such as a navigation light, an antenna and a radar is installed.

In recent years, the height of the mast has become higher as the height of the mast gradually increases with the tendency of the ship becoming larger. If the height of the mast increases, it will interfere with the passage of the ship through the bridge or canal due to the height of the mast when passing through the bridge or the canal, depending on the condition of the route during the voyage. Accordingly, there is a need for a mast tilting device for lowering the height of the mast by inclining the mast when the ship passes the bridge or canal having a height lower than the height of the mast.

Korean Patent Laid-Open Publication No. 10-2013-0031451 discloses an example of a conventional mast tilting apparatus.

Hereinafter, the conventional mast tilting apparatus disclosed in the above publication will be described with reference to the drawings.

FIG. 1 is a view showing a conventional mast tilting apparatus, and FIG. 2 is an enlarged view of FIG.

1 and 2, a conventional mast tilting apparatus 1 includes a base 13 provided on a radar mast 11 formed on a ship, a hinge block 14 provided on a base 13, The signal post 12 is integrally formed with the base 13 such that the signal post 12 is not rotated by more than a predetermined angle when the signal post 12 is pivoted about the hinge block 14, A lifting eye 16 formed at one side of the signal post 12 opposing the position of the stopper 15 and a lifting eye 15 and a wire rope 17 are bound together A chain block 18 in conjunction with the wire rope 17 to pull the signal posts 12 and a lug 19 formed in the radar mast 11 to support the chain block 18. [

In the conventional mast tilting apparatus 1, in order to lay down the signal post 12, the chain block 18 loosens the wire rope 17 so that the operator directly lays down the signal post 12, When the wire rope 17 is loosened, the signal post 12 is laid down by its own weight.

However, in the conventional mast tilting apparatus 1, when the signal post 12 is laid down, the operator must first lay down the signal post 12 directly, which may cause a safety accident of the operator.
