Description

Technical Field

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

[0002] Inclined ladders are widely used facilities in the field of ships and are the main passages between decks on ships. Traditional inclined ladders are mainly made of metal, with steel and aluminum ladders being the most commonly used. Steel inclined ladders are heavy and prone to rust and corrosion. Hot-dip galvanizing can improve the anti-corrosion performance, but it is difficult to improve the surface finish and aesthetics. Aluminum inclined ladders are light, strong and rigid, so domestic and foreign ships currently tend to use aluminum inclined ladders. However, aluminum alloys are prone to damage due to their low hardness, especially in outdoor environments, which require timely on-site repair.

[0003] In order to meet the lightweight requirements of modern ships, the inclined ladder must not only reduce the weight as much as possible, but also meet the requirements of hardness, strength and corrosion resistance. It is necessary to optimize the design of the ship inclined ladder. Utility Model Content

[0004] The utility model aims to provide a marine inclined ladder to solve the problem that the weight, hardness, strength and anti-corrosion performance of the existing inclined ladder cannot be guaranteed at the same time.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A marine inclined ladder comprises a ladder frame, with feet arranged at both ends of the ladder frame, the feet at both ends being fixedly connected to an upper deck and a lower deck respectively, a plurality of pedals increasing in height step by step are arranged on the ladder frame, the ladder frame and the pedals are both made of composite plates, the composite plates comprise carbon fiber layers on both side surfaces, PET filler is arranged between the two carbon fiber layers, and handrails are arranged on the ladder frame and on both sides of the pedals.

[0007] Optionally, both side surfaces and the bottom surface of the ladder frame are provided with dustproof plates, and the dustproof plates are also made of composite plates.

[0008] Optionally, the surface of the pedal is formed with convex ribs for anti-slip.

[0009] Optionally, the handrail is made of a composite rod material, the surface of the composite rod material is a carbon fiber layer, and the interior of the composite rod material is a PET filler.

[0010] Optionally, a reinforcing pad is provided on the lower surface of the upper deck at the installation position corresponding to the pier foot, the reinforcing pad abuts against the pier foot, a first bolt is passed through the upper deck, and the first bolt passes through the pier foot and is fastened with a first nut.

[0011] Optionally, a fixed pad is provided on the upper surface of the lower deck at the installation position corresponding to the pier foot, the fixed pad abuts against the pier foot, a second nut is embedded in the fixed pad, and a second bolt that cooperates with the second nut is passed through the pier foot.

[0012] In summary, compared with the existing technology, the marine inclined ladder is built with a composite plate made of carbon fiber and high-strength PET material. Compared with conventional steel inclined ladders and aluminum inclined ladders, the overall weight reduction is obvious, and it has sufficient hardness, strength, wear resistance and corrosion resistance.

[0021] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 As shown, the preferred embodiment provides a marine inclined ladder, including a ladder frame 1, two ends of the ladder frame 1 are provided with footrests 2, the footrests 2 at both ends are respectively fixedly connected to the upper deck 3 and the lower deck 4, and the ladder frame 1 is provided with a plurality of pedals 5 with gradually increasing heights. The ladder frame 1 and the pedals 5 are both made of a composite sheet material, and the composite sheet material includes a carbon fiber layer 6 located on both side surfaces, and a PET filler 7 is arranged between the two carbon fiber layers 6. For details, see Figure 2 Handrails 8 are provided on the ladder frame 1 and on both sides of the pedal 5.

[0023] Therefore, the marine inclined ladder is built with composite panels made of carbon fiber and high-strength PET material. Compared with conventional steel inclined ladders and aluminum inclined ladders, the overall weight reduction is obvious, which can reduce the weight by about 60%. It has sufficient hardness, strength, wear resistance and corrosion resistance, simple structure, reduced welded parts, ensuring the connection stability and reliability of the inclined ladder, and has a longer service life.

[0024] As an optional solution, both sides and the bottom of the ladder frame 1 are provided with dustproof plates 9, which are also made of composite plates. In addition to the dustproof function, the dustproof plates 9 here can also enhance the overall structure of the inclined ladder and facilitate the reliable fixing of the pedals 5 and the handrails 8.

[0025] As an optional solution, the surface of the pedal 5 is formed with convex ribs 10 for anti-slip. Specifically, the convex ribs 10 are integrally formed on the surface of the pedal 5 when it is manufactured. In view of the wear-resistant and impact-resistant properties of the carbon fiber material, the pedal 5 can have sufficient anti-slip and wear-resistant capabilities.

[0026] As an optional solution, the handrail 8 is made of a composite rod material, the surface of the composite rod material is a carbon fiber layer 6, and the interior of the composite rod material is a PET filler 7, see Figure 3 The handrail 8 is made of the same material as the ladder frame 1 and the pedal 5, so the integrity is better and the strength is guaranteed. In addition, the carbon fiber material improves the comfort of the person holding the handrail 8.

[0027] As an optional solution, the specific connection structure between the ladder frame 1 and the upper deck 3 is shown in Figure 4A reinforcing pad 11 is provided on the lower surface of the upper deck 3 at the installation position corresponding to the code foot 2. The reinforcing pad 11 is in contact with the code foot 2. A first bolt 12 is passed through the upper deck 3.

[0028] As an optional solution, the specific connection structure between the ladder frame 1 and the lower deck 4 is shown in Figure 5 A fixed pad 14 is provided on the upper surface of the lower deck 4 corresponding to the installation position of the pier 2. The fixed pad 14 abuts against the pier 2, and a second nut 15 is embedded in the fixed pad 14. A second bolt 16 that cooperates with the second nut 15 is passed through the pier 2, thereby facilitating assembly operations and ensuring reliable connection.
