Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention is a roller for relaying and holding an anchor chain stretched in the lateral direction of a hull from a gypsy wheel of a windlass arranged on both sides of a mooring deck of a bow in front of a hose pipe. Type chain compressor.

[0002]

2. Description of the Related Art Conventionally, the invention of this type has been such that an anchor chain which is lifted and lowered by a windlass is slid on a mooring deck of a bow portion of a roller which is held by a frame side of a main body of a chain compressor which is arranged immediately before a hose pipe. Move,
A roller type chain compressor is known in which an anchor is suspended at a lower end of the roller chain compressor, which is electrically connected to the inside of the hose pipe.

[0003]

In the roller type chain compressor described in the prior art, when the installation place of the windlass on the mooring deck of the bow is limited, the anchor chain is stretched on both lateral sides of the ship. Since the hose pipe is installed in the vertical direction and electrically connected to the hose pipe, the angle formed by the anchor chain at the portion sliding on the roller of the chain compressor becomes about 110 degrees. In view of the relative relationship of (1), the radius of curvature of the ring in the sliding portion is small, and the load applied to the ring in contact with the groove of the roller is increased, causing the ring to be curved and deformed.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a roller type chain compressor that reduces the load on the ring of the anchor chain. It is what

[0005]

In order to achieve the above object, the present invention provides an anchor chain extending laterally of a hull from a gypsy wheel of a windlass disposed on both sides of a bow mooring deck. In a roller type chain compressor that relays and holds immediately before the hose pipe arranged vertically downward, inside each frame side of the chain compressor that holds both ends of the roller shaft, and in front of the arc lower part of the upper part of the roller. An arc-shaped chain guide is projected at the adjacent position so that it is almost the same as the inner surface of the hose pipe, and the anchor chain slides on each arc of the roller and the chain guide to make a gentle bend. is there.

[0006]

The arc-shaped chain guide provided at a position adjacent to the front of the lower part of the arc above the roller forms a radius of curvature larger than the radius of curvature of the roller by the arc of the roller and the arc of the chain guide. It is possible to slide with a gentle curvature.

[0007]

EXAMPLES Examples will be described with reference to the drawings.
As shown in FIGS. 1 to 3, an anchor chain 5 is stretched in the lateral direction of the hull from the gypsy wheels of the windlass 9 arranged on both sides of the bow mooring deck 1 and arranged vertically downward. Just before the hose pipe 7, the chain compressor 2
It is relayed and held at, is conducted to the inside of the hose pipe 7, and the anchor is suspended at the lower end.

In the chain compressor 2, the main body side frame 8 holds both ends of the roller shaft 3, and the arc is formed inside each of the main body side frames 2 and at a position adjacent to the front lower part of the arc above the roller 4. A chain guide 6 of a shape is provided so as to be substantially the same as the inner surface of the hose pipe, and the anchor chain 5 is slid on each arc portion of the roller 4 and the chain guide 6.

[0009]

Since the present invention is constructed as described above, it has the following effects. The anchor chain can be slid with a large curvature formed by the arc of the roller and the chain guide, the load on the ring of the anchor chain that abuts the groove of the roller is reduced, and the ring is not curved and deformed.
