Description

Limiting structure of cabin in longitudinal direction

Technical Field

The utility model relates to the field of ship structures, in particular to a limiting structure of a cabin in the longitudinal direction.

Background

The cargo hatches of the container ship are provided with several hatches along the width of the ship, which are prevented from moving longitudinally by means of stops mounted on the hatches at the bulkheads, one for each hatch. Normally, to ensure that the covers are flush front to back when placed on the stops, the stops of each cargo compartment cover are located on a hatch coaming at the same location, and it is possible to place them either at the rear end of the compartment or at the front end of the compartment.

For ships with larger widths of the watertight bulkhead and the supporting bulkhead, the stoppers can be uniformly arranged at the front end or the rear end of each cabin in a sequential arrangement. However, for some ships with smaller support bulkhead widths, the sequential placement as described above may result in excessive deformation of the support bulkheads, difficulty in meeting the fit requirements between equipment such as hatches, columns, etc., requiring significant reinforcement, which may add significant structural weight. While a uniform movement of the stops on the supporting bulkhead to the position of the watertight bulkhead, i.e. the watertight bulkhead with the deck lid stops of two adjacent compartments arranged, may be suitable for small container ships, but for larger container ships this may result in too large a displacement on the watertight bulkhead, which may also add a lot of structural weight to meet the displacement requirements, or increase the width of the bulkhead.

SUMMERY OF THE UTILITY MODEL

In view of the above, it is necessary to provide a limiting structure in the longitudinal direction of a ship cabin, which can satisfy the displacement requirement between a cabin cover and other equipment.

A limit structure of a cabin longitudinal direction comprises watertight bulkheads, supporting bulkheads, a hatch cover, limit devices and hatch coamings, wherein the supporting bulkheads are located between two adjacent watertight bulkheads, two ends of the hatch cover are located at the top ends of the watertight bulkheads and the top ends of the supporting bulkheads respectively, one end of the hatch cover is installed on one bulkhead through one first limit device, and the other end of the hatch cover is installed on the other bulkhead through two second limit devices which are opposite to each other by taking the first limit device as a center line.

Furthermore, a cabin inner cavity is formed between the watertight bulkhead and the supporting bulkhead, and the cabin inner cavity is divided into two edge areas and a middle area.

Further, the hatch cover may be divided into a plurality of independent bodies.

Further, the first position limiter is mounted on the watertight bulkhead or the supporting bulkhead in the middle area, and the two second position limiters are mounted on the watertight bulkhead or the supporting bulkhead in the edge area, respectively.

Furthermore, a hatch coaming is installed on the side wall of the inner cavity of the cabin body, and the top end of the hatch coaming is close to the hatch cover.

Furthermore, one end of the limiting stopper is fixed on the hatch coaming, and the other end of the limiting stopper is inserted in the hatch cover.

According to the limit structure of the longitudinal direction of the cabin, the limit devices are respectively arranged on the two opposite cabin walls according to the matching displacement requirements of the cabin cover on the equipment such as the box legs, the upright post box legs and the cabin cover sealing base plate, so that the load of part of the cabin cover limit devices is only borne on each cabin wall, the relative deformation between the cabin walls is more consistent, and the structural utilization is more sufficient.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, 2 and 3, wherein fig. 1 is an arrangement of a conventional hold limiting structure in a longitudinal direction of a cabin. In one embodiment, a limiting structure of a longitudinal direction of a cabin includes watertight bulkhead 100, supporting bulkhead 200, hatch cover 300, limiter 400 and hatch coaming 500, supporting bulkhead 200 is located between two adjacent watertight bulkheads 100, two ends of hatch cover 300 are respectively located at a top end of watertight bulkhead 100 and a top end of supporting bulkhead 200, one end of hatch cover 300 is mounted on one bulkhead through one first limiter, and the other end of hatch cover 300 is mounted on the other bulkhead through two second limiters opposite to each other with the first limiter as a center line. The stopper 400 proposed in this embodiment is a longitudinal stopper, except for the specific description.

According to the limit structure of the longitudinal direction of the cabin, the limit devices 400 are respectively arranged on two opposite cabin walls according to the matching displacement requirements of equipment such as the cabin cover upper box legs, the upright post box legs and the cabin cover sealing base plate, so that the load of the limit devices 400 of the part of the hatch covers 300 is borne on each cabin wall, the relative deformation between the cabin walls is more consistent, the structural utilization is more sufficient, and the relative deformation is smaller.

In this embodiment, watertight bulkhead 100 and support bulkhead 200 define a chamber therebetween that is divided into two edge regions and a middle region. The hatch cover 300 may be divided into three independent bodies according to three regions, or divided into a plurality of independent bodies separately.

In this embodiment, a first stop is mounted on watertight bulkhead 100 or supporting bulkhead 200 in the middle region, and two second stops are mounted on watertight bulkhead 100 or supporting bulkhead 200 in the edge regions, respectively.

In this embodiment, a hatch coaming 500 is installed on the inner cavity side wall of the cabin, and the top end of the hatch coaming 500 is close to the hatch cover 300. Used for sealing the inner cavity of the cabin body and preventing water from entering.

In this embodiment, one end of the stopper 400 is fixed to the hatch coaming 500, and the other end of the stopper 400 is inserted into the hatch cover 300. The stopper 400 is provided in a columnar structure.

Because the stop 400 of part hatch cover is not on same hatch coaming 500, in order to guarantee that after hatch cover 300 inserts stop 400, the front and back terminal surface is the same level, adopt bayonet vertical stop 400, during horizontal hatch coaming 500 is inserted to this kind of stop 400 partly, need not extra location, can solve the problem that the hatch cover in same hatch aligns.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
