Abstract

(57) [Summary] [Purpose] This is a steel rope anti-friction metal that is fixedly installed in the cargo hold of a cargo ship. Steel rope anti-friction hardware characterized by avoiding danger. [Structure] Inside the cargo hold surrounded by the cargo hold edge material 1, the lower surface of the upper deck extension portion 2 extending to the corner portion of the cargo hold edge material 1 and the cargo hold girder 5 are contacted. A plurality of flat bar support members 4 made of flat steel plates which are fixedly contacted with each other, and a steel semi-welding member which is welded to the tip end portion of the support members 4 along the arc shape of the edge portion of the upper deck extending portion 2. A steel rope anti-friction metal fitting composed of a round bar 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is to fix the extended upper deck of the steel rope of the cargo handling device fixed to the edge portion of the upper deck extending in an arc shape at the corner portion of the edge member of the cargo mouth of the cargo hold of the cargo ship. The present invention relates to a hardware for preventing damage caused by friction with an edge portion.

[0002]

[Prior art]

 Conventionally, as this kind of steel rope anti-rubbing metal, as shown in FIG. 3 to FIG. 4, steel made of steel along the edge of the upper deck 21 extending to the corner 22 of the cargo rim of the cargo hold is provided. It is known that the half-round bar 23 is fixed.

[0003]

[Problems to be solved by the device]

 In the conventional technology described above, the cargo hold mouth is deformed due to repeated cargo voyage during full sailing and empty ship sailing, and shock due to waves, etc. Concentrated on the corners of the material 22, cracks occur in the welded parts of the upper deck 21 and the steel semi-circular bar 23, and steel wires for cargo handling are sandwiched in the cracks, and frictional action with the cracks occurs. Therefore, there is a problem that the steel rope is damaged or cut.

The present invention has been made in view of the above problems of the prior art, and its object is to make an edge portion of the upper deck extension portion in the cargo hold mouth and a steel semi-circle. An object of the present invention is to provide a steel rope rubbing preventive metal that does not cause cracks between the rods and does not damage the steel rope such as cutting or uneven wear.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the steel rope anti-rubbing metal fitting in the present invention is an upper deck extension that extends inside the cargo hold mouth surrounded by the cargo hold mouth edge material and extends to the corner portion of the cargo hold mouth edge material. A plurality of flat-plate steel half-round bar supporting members that are welded to the lower surface of the section and the cargo hold girder, and a steel half-round bar that is welded to the tip of the half-round bar supporting member. Half-round bar The arc-shaped steel half-round bar is welded to the tip of the supporting material, the upper deck edge, and the cargo hold girder.

[0006]

[Action]

 Since the steel semi-round bar is not directly fixed to the edge portion of the upper deck extension portion, the deformation of the semi-round bar portion slows down the crack propagation on the upper deck extension portion.

[0007]

【Example】

 Examples will be described with reference to the drawings. In FIGS. 1 and 2, the steel rope anti-rubbing metal is inside the cargo hold surrounded by the cargo hold edge material 1 and abuts on the lower surface of the upper deck extension portion 2 and the cargo hold girder 5 to be fixed. , The other end is welded with a plurality of half-round bar support members 4 made of flat steel plates having notches with a gentle downward slope toward the inside.

By making contact with the tips of the plurality of semi-circular bar support members 4 and bending them along the arc of the edge of the upper deck extension 2 in advance, both ends are tapered smoothly. The semi-circular rod 3 made of steel and processed into a shape is welded.

[0009]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

Since the semi-round bar made of steel does not directly contact the upper deck extending portion, it is difficult for a crack to propagate from the side of the half round bar to the upper deck extending portion, which may be caused by cutting or uneven wear. It is possible to prevent damage to the steel rope.
