Description

Technical Field

[0001] The utility model relates to the technical field of ship design, in particular to a ship ladder and a ship. Background Art

[0002] As a multi-story building, ships are usually equipped with stairways surrounded by steel enclosures. There are multi-layer ladders and multi-layer transfer platforms inside the stairways. When designing the steel enclosures, it is ideal not to set stiffeners inside the stairways to retain the maximum passage space. However, for the sake of the strength and stability of the stairway structure, stiffeners must be set inside the stairways in some cases. At the same time, according to the requirements of the specifications, the ends of the stiffeners of the watertight or wind and raintight bulkheads are generally not allowed to be cut obliquely. Since the stiffeners are long, they need to be reinforced. However, the traditional method is generally to fix the stiffeners to the inner wall of the enclosure at the position corresponding to each deck through supporting structures such as brackets. When people walk on the transfer platform between two adjacent decks, the brackets and other supporting structures are prone to cause people to bump heads, which also reduces the net space in the stairway, affecting the comfort and safety of people passing.

[0036] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0038] The following first describes in detail the ship ladder according to an embodiment of the first aspect of the utility model with reference to the accompanying drawings.

[0039] Figure 1 This is a schematic diagram of the structure of a ship ladder according to an embodiment of the utility model. Figure 2 This is a schematic top view of a ship according to an embodiment of the utility model. Figure 3 The present invention is a partial structural schematic diagram of a ship ladder according to an embodiment of the present invention.

[0040] Specifically, Figures 1 to 3 As shown, the ship stairway according to the embodiment of the utility model may include: a stairway room, a plurality of first platforms 3, a plurality of second platforms 4, a plurality of ladders 5 and a plurality of stiffeners 6.

[0041] The stairway is surrounded by a wall and passes through each deck 100 of the ship in the vertical direction. The wall includes a first wall 1 and a second wall 2 that are arranged opposite to each other. A plurality of first platforms 3 are located in the stairway and are arranged on the first wall 1 in sequence in the vertical direction. The first platforms 3 correspond to the decks 100 one by one, and each first platform 3 is flush with its corresponding deck 100. A plurality of second platforms 4 are located in the stairway and are arranged on the second wall 2 in sequence in the vertical direction. There is a second platform 4 corresponding to the middle between two adjacent first platforms 3. Each second platform 4 is connected to its corresponding two adjacent first platforms 3 by an inclined ladder 5. A plurality of stiffeners 6 are located in the stairway and are arranged on the second wall 2 in sequence in the vertical direction. Each stiffener 6 passes through each second platform 4 and is connected to each second platform 4.

[0042] Specifically, a plurality of stiffeners 6 are directly arranged on the second enclosure 2 in sequence along the vertical direction, and each stiffener 6 passes through each second platform 4 and is connected to each second platform 4, and each second platform 4 is directly used as a supporting point for each stiffener 6, thereby eliminating traditional supporting structures such as toggle plates. On the one hand, when personnel walk on the second platform 4, there will be no head collision, thereby improving the safety of personnel passage; on the other hand, the net space inside the stairway is increased, thereby improving the comfort of personnel passage. In addition, the stability of the stiffener 6 is also improved, and the use of the stiffener 6 can be reduced, thereby reducing costs. For example, in a traditional ship stairway, due to the influence of supporting structures such as toggle plates, the net space at a position corresponding to each deck 100 in the stairway is usually 3250 mm; while in the ship stairway of the present application, such as Figure 2 As shown, the clear space d at the position corresponding to each deck 100 in the stairway can reach at least 3450 mm.

[0043] Therefore, the ship stairway provided by the utility model can avoid the situation where people collide with each other by directly using each second platform 4 as the supporting point of each stiffening material 6, increase the net space inside the stairway, take into account safety regulations and actual use needs, improve the comfort and safety of people's passage, reduce the use of stiffening materials 6, and reduce costs.

[0044] In some embodiments of the present invention, reference Figure 2, multiple stiffeners 6 are arranged in parallel at equal intervals. Thus, multiple stiffeners 6 arranged in parallel at equal intervals are used to be set on the second enclosure 2, and a stable support is formed through the synergistic effect between the multiple stiffeners 6, which can directly enhance the rigidity of the second enclosure 2, thereby effectively dispersing the load applied to the second enclosure 2 (including the weight of the deck 100, the load of the movement of personnel and cargo, and the sway and torsion load caused by the impact of waves during navigation, etc.), reducing local stress concentration, avoiding the formation of structural weak points, and effectively improving the stability and durability of the ship's ladder.

[0045] In some embodiments of the present invention, reference Figure 3 Each stiffener 6 is welded to each second platform 4, and each second platform 4 is provided with a through hole 41 for each stiffener 6 to pass through. That is to say, on the one hand, welding can withstand large tensile, compressive and shear forces, and is suitable for the ship ladder structure of the present application to withstand various dynamic loads encountered during the navigation of the ship. On the other hand, by presetting the through hole 41 on the second platform 4, an accurate positioning point is provided for the installation of the stiffener 6, which reduces the installation error, improves the construction efficiency, avoids the material waste and labor cost that may be caused by on-site drilling, and simplifies the installation procedure.

[0046] In some embodiments of the present invention, an inner panel (not shown) is disposed outside each stiffener 6 , and each inner panel is located in the stairwell and passes through each through hole 41 corresponding to the stiffener 6 along the vertical direction.

[0047] Specifically, the operator can pre-process openings matching the size of the corresponding stiffener 6 on the inner panel according to the position and size of the stiffener 6, then align the stiffener 6 through these opening structures, and finally fix the inner panel to the stiffener 6 with bolts, buckles or other fixings. In this way, the stiffener 6 and each through hole 41 can be effectively covered to ensure the beauty of the interior of the ship's stairway, and at the same time, the connection between the inner panel and the stiffener 6 can be sealed, thereby preventing the stiffener 6 from being eroded by environmental factors such as seawater to a certain extent, and improving the durability of the structure.

[0048] In some embodiments of the present invention, reference Figure 1 The upper surface of each first platform 3 and the upper surface of each second platform 4 are both horizontal surfaces. This makes it easier for operators to stand and walk stably and safely, especially when the stairway is slippery or emergency evacuation is required. In addition, the horizontal surface is simple in design, easy to construct, and easy to manufacture and install.

[0049] In some embodiments of the present invention, reference Figure 1, the thickness of each first platform 3 along the vertical direction gradually decreases from the end connected to the first surrounding wall 1 to the end away from the first surrounding wall 1. The thickness of each second platform 4 along the vertical direction gradually decreases from the end connected to the second surrounding wall 2 to the end away from the second surrounding wall 2. That is to say, during installation, the thicker end of the first platform 3 is close to the first surrounding wall 1, and is connected to the first surrounding wall 1 by welding or other fixing methods to provide stable support. The thickness of the first platform 3 along the vertical direction gradually decreases from the end connected to the first surrounding wall 1 to the end away from the first surrounding wall 1, and the deadweight of the first platform 3 is reduced, which not only saves materials, but also achieves optimal force distribution and ensures structural strength. Similarly, during installation, the thicker end of the second platform 4 is close to the second surrounding wall 2, and is connected to the second surrounding wall 2 by welding or other fixing methods to provide stable support. The thickness of the second platform 4 along the vertical direction gradually decreases from the end connected to the second surrounding wall 2 to the end away from the second surrounding wall 2, and the weight of the second platform 4 is reduced, which not only saves materials, but also achieves optimal force distribution and ensures structural strength. The first platform 3 and the second platform 4 can be of the same structure or different structures, which is not limited in this application.

[0050] In some embodiments of the present invention, reference Figure 3 , each first platform 3 and each second platform 4 are frame structures, and each first platform 3 and each second platform 4 are respectively provided with support members 7. That is to say, in the design of ship ladders, the frame structure can effectively distribute the load to multiple transverse support members or longitudinal support members (such as beams and columns), rather than concentrating on a few points or lines. As a result, the overall stability and carrying capacity of the platform can be effectively improved. In addition, each first platform 3 and each second platform 4 are respectively provided with support members 7, which further ensures the stability and carrying capacity of the platform.

[0051] In some embodiments of the present invention, reference Figures 2 to 3 The enclosure wall further includes two side enclosure walls 8 arranged opposite to each other, one end of the two side enclosure walls 8 is respectively connected to the first enclosure wall 1, and the other end of the two side enclosure walls 8 is respectively connected to the second enclosure wall 2. The two side enclosure walls 8, the first enclosure wall 1 and the second enclosure wall 2 form a stairway room, and the two sides of each first platform 3 and the two sides of each second platform 4 are respectively connected to the two side enclosure walls 8. In other words, the two side enclosure walls 8, the first enclosure wall 1 and the second enclosure wall 2 form a closed stairway room with a rectangular cross section, so that it can withstand loads from all directions. Therefore, the structure is simple, stable and reliable.

[0052] In some other embodiments of the present invention, reference Figures 2 to 3A plurality of equally spaced stiffeners 6 can be provided on the outer wall of the first enclosure 1 and the outer walls of the two side enclosures 8. Thus, the structural strength of the ship's ladder can be further enhanced, and the stability and safety of the ladder can be improved.

[0053] In some embodiments of the utility model, each first platform 3, each second platform 4 and each ladder 5 are respectively provided with anti-skid parts (not shown), and the first surrounding wall 1 is provided with doors (not shown) corresponding to each first platform 3. That is to say, anti-skid parts can be provided on each first platform 3, each second platform 4 and each ladder 5, and the anti-skid parts can be rubber pads, etc., so as to further improve the safety of walking inside the ship's ladder in a slippery environment on rainy days, or in an environment with water, oil and the like. At the same time, doors corresponding to each first platform 3 can be provided on the first surrounding wall 1, so as to facilitate personnel to enter and exit the corresponding floors, thereby improving the portability and practicality of the ship's ladder.

[0054] According to the second embodiment of the utility model, the ship Figures 1 to 3 , including the ship stairway of any embodiment of the first aspect. The ship provided by the utility model adopts the ship stairway, and by directly using each second platform 4 as the support point of each stiffener 6, it can avoid the situation where people bump into each other, increase the net space inside the stairway, take into account safety regulations and actual use needs, improve the comfort and safety of people passing, reduce the use of stiffeners 6, and reduce costs.

[0055] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
