The problems of difficulty in unloading and stress at the corner of the cargo hold in the prior art are effectively solved, and cargo overstock and stress concentration are avoided.

Description

Cargo compartment corner structure

Technical Field

The utility model relates to a shipbuilding field, concretely relates to cargo hold corner structure.

Background

The large-scale bulk cargo, ore sand ship have a plurality of main deck cargo holds big opening, in order to satisfy boats and ships intensity requirement, main deck big opening department needs the hatch coaming structure to strengthen it. Any trompil needs the fillet transition on the boats and ships, and the goods can be piled up in the region that hatch encloses structure and opening fillet enclose like this, so treat that the goods shipment all needs the special messenger to go the clearance after finishing, influence the unloading efficiency. In the prior art, cargo unloading plates are used to prevent the accumulation of cargo, but the strength and stress of the corners are affected by the installation of the cargo unloading plates at the corners of the cargo compartment.

Disclosure of Invention

The problem of cargo hold corner unloading difficulty and stress among the prior art is solved, the utility model aims to provide an avoid goods overstock, avoid stress concentration's cargo hold corner structure.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

the utility model provides a cargo hold corner structure, encloses including deck and hatch, and the hatch encloses the perpendicular to deck, the welding has the board of unloading between the interior right angle face that the hatch encloses and the deck, the board of unloading is the triangle-shaped steel sheet, the board plane of unloading is 45 degrees contained angles with the deck plane, two sides of the board of unloading and the inner wall welded connection that the hatch encloses, the bottom segment and deck and the hatch of unloading base and two sides enclose and leave the clearance between, form the free end, pack silica gel in the clearance.

Further, the deck on the inner side of the hatch coaming is an arc-shaped opening corner.

Furthermore, a weather inhibitor is placed in an enclosed space formed by the unloading plate, the deck and the inner wall of the hatch coaming.

And furthermore, a liner is attached to the back of the unloading plate, and the unloading plate, the liner and the hatch coaming are in single-side groove welding connection.

After taking above technical scheme, the beneficial effects of the utility model are that: utilize the structure of the discharge board of 45 degrees, can make the automatic landing of goods, can avoid piling up. The positions of the unloading plates, which are close to the corners of the deck, are welded in a silica gel filling mode, so that the influence of welding stress on the corners is effectively avoided; the back of the unloading plate is adhered with a liner and welded, so that water corrosion is prevented, and the service life of the unloading plate is prolonged by adopting a weather inhibitor.

Drawings

FIG. 2 is a schematic view of the welding of the present invention;

fig. 3 is a cross-sectional view of the present invention.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in the figure, the corner structure of the cargo compartment comprises a deck 1, a hatch coaming 2 and a cargo unloading plate 3, wherein the hatch coaming 2 is vertically welded on the deck 1, and a circular arc-shaped opening 4 of the deck between inner right-angle surfaces of the hatch coaming 2 forms a corner. The unloading plate 3 is welded between the inner right angle of the deck 1 and the hatch coaming 2, the unloading plate 3 is a triangular steel plate, the plane of the unloading plate 3 and the plane of the deck 1 form an included angle of 45 degrees, and a weather inhibitor 5 is placed in an enclosed space formed by the unloading plate 3, the deck 1 and the inner wall of the hatch coaming 2. Angle steel gaskets 6 are attached to the back surfaces of two side edges of the unloading plate 3, the top angle of the unloading plate 3 is welded downwards along two bevel edges of the unloading plate 3, the gaskets 6, the unloading plate 3 and the hatch coaming 2 are welded simultaneously in a single-side groove welding mode, the welding is stopped until the position 100mm away from the deck is welded, the connecting seams are filled and sealed by silica gel 7, a 15mm gap is reserved between the bottom edge of the unloading plate 3 and the deck, and the gap is filled with silica gel 7 for sealing. Namely, the bottom end of the unloading plate forms a free end, so that the stress is conveniently released, and the welding stress is prevented from influencing corners.

The construction method of the corner structure comprises the following steps:

1. before welding, the unloading plate 3 is polished smooth, and particularly the free edge of the contact area of the lower opening and the deck 1 needs to be polished.

2. And finishing painting the closed area before welding.

3. And (3) placing 300g of weather inhibitor 5 in the closed area before welding.

4. The unloading plate 3 and the hatch coaming 2 are welded by adopting a single-side groove, and the back side is pasted with a liner for welding. The place 100mm away from the deck is filled with silica gel.

5. The offloading board 3 is filled with silicone gel at the corners of the deck 1.

6. And (5) polishing the welded weld joints and painting.

Claims
