Description

A ballast tank structure that facilitates inspection and maintenance

Technical field

The utility model belongs to the field of ship technology, and specifically relates to a ballast tank structure that is convenient for maintenance.

Background technique

According to SOLAS requirements, bulk carriers and oil tankers must meet PMA requirements and set up permanent structural maintenance channels. The connection between the hopper tank sloping plate and the outer plate of a single-hull bulk carrier needs to be inspected. The conventional design is to outfit and make an inspection platform, which adds a lot of materials and is a waste of space. On the other hand, when using a portable ladder, you need to carry the ladder with you in the ballast tank during inspection, which is very inconvenient and the inspection takes a long time. Using this kind of inclined ladder to climb up for inspection also involves safety risks.

Utility model content

In view of the technical problems mentioned above, the present utility model provides a ballast tank structure that facilitates personnel to inspect and repair the ballast tank, improves the safety and convenience of personnel during inspection, and can also reduce the construction workload and space. Boat quality.

In order to achieve the purpose of this utility model, the technical solutions adopted are as follows:

A ballast tank structure that is convenient for maintenance, including a cabin structure composed of an outer plate, a sloping plate, and an inner bottom plate. The outer plate is provided with ribs that are perpendicular to and evenly distributed therewith. The outer plate is provided with ribs on the inside of the side. An inspection platform is arranged horizontally along the length of the hull. The inspection platform penetrates the floor plate, and a through hole is provided on the floor plate above the inspection platform. There are two ends of the inspection platform connected to the outside of the bottom. board ladder.

Further, the inspection platform is an expanded longitudinal frame.

Further, the maintenance platform is located within 2.5-3m of the connection between the outer plate and the inclined plate.

Further, the width of the maintenance platform is 60~70cm.

Furthermore, handrails are provided on the edge of the inspection platform.

Compared with the existing technology, the beneficial effects of this utility model are:

By setting an inspection platform on the side of the outer plate, and setting a through hole on the floor plate for pedestrians to pass through, and setting ladders at both ends of the inspection platform, it is convenient for personnel to inspect the connection between the outer plate and the inclined plate of the ballast tank. Carry out maintenance, improve the safety of maintenance personnel, and can also reduce the construction workload of outfitting, reduce the weight of the empty ship, and increase the cargo capacity.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. For example, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

Referring to Figures 1-2, the utility model provides a ballast tank structure that is convenient for maintenance, including a cabin structure composed of an outer plate 1, a sloping plate 2, and an inner bottom plate 3. The outer plate 1 includes a side With the bottom, the inclined plate 2 has an inclined end and is welded and fixed to the side of the outer plate 1, and the other end is welded and fixed to the inner bottom plate 3. The outer plate 1 is provided with ribs 4 perpendicular to it and evenly distributed. There is an inspection platform 5 arranged horizontally along the length of the hull on the inside. The inspection platform 5 is a plate-like structure. The inspection platform 5 is vertically welded to the side outer plate. The inspection platform 5 penetrates the floor plate 4 provided on the outer plate, and its Extending from one end of the hull to the other end; the rib 4 located above the access platform 5 is provided with a through hole 40 for personnel to pass through. The shape of the through hole 40 can be set to an oval, and its size can be designed according to specific conditions; Ladders 6 connected to the bottom outer panel are provided at both ends of the inspection platform 5. The ladders 6 can be used by workers to get up and down the inspection platform 5 when performing inspection operations.

In order to further save the construction workload during hull outfitting, a longitudinal frame on the side of the outer plate 1 can be extended to be used as the maintenance platform 5. At the same time, in order to meet the working space needs of the staff on the maintenance platform 5, the The width of the inspection platform 5 is set to 60~70cm, and the position of the inspection platform 5 needs to be within 2.5~3m of the connection between the outer plate and the inclined plate, so that the staff can clearly observe the inspection place when performing inspections. .

In order to ensure the personal safety of workers during maintenance, handrails 7 are also provided on the edge of the maintenance platform 5 .

In this embodiment, by arranging the inspection platform 5 through the floor plate on the side outer plate 1, the floor plate 4 can be used to provide support for the inspection platform 5, thereby reducing construction tasks. In addition, through holes are provided on the floor plates for pedestrians to pass through, and ladders are provided at both ends of the inspection platform, which can facilitate personnel to inspect the connection between the outer plate and the inclined plate of the ballast tank, improving the safety of inspection personnel. , and it can also reduce the outfitting construction workload, reduce the weight of the empty ship, and increase the cargo capacity.

The embodiments of the present utility model are described in detail above with reference to the accompanying drawings, but the utility model is not limited to the described embodiments.
