Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a channel platform for a ship's outer plating. Background Technology

[0002] In ship design, liquid compartments and sewage outlets are typically located on the port and starboard sides of the hull bottom. These are areas frequently accessed by the crew. The outer plating of the hull bottom is often a complex curved surface. On gently sloping plating structures, anti-slip strips can be installed to facilitate crew passage. However, some ship types have narrower hull lines and steeper outer plating sections. Even with anti-slip strips, normal passage is not possible, often requiring the use of angle steel to construct passageways during outfitting. Since the installation of these angle steel passageways occurs later than the installation of anti-slip strips, direct welding on the outer plating structure is generally not permitted. This results in complex angle steel platforms that consume a significant amount of material, increasing the overall weight of the ship's outfitting and negatively impacting the ship's economic efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a passage platform for the outer plating of a ship, which reduces the structural impact on the outer plating, effectively saves on outfitting fabrication and installation costs and reduces the overall weight of the ship outfitting, and has a flexible and highly adaptable overall structure.

[0004] To achieve the above objectives, the present invention provides a passage platform for a ship's outer plating, including ribs disposed on the outer plating and a plurality of step devices disposed between two adjacent ribs; the step device includes a pedal, a first support leg, a second support leg, and a mounting rod, the first support leg and the second support leg being respectively connected to the left and right ends of the mounting rod, the pedal being fixed to the top surface of the mounting rod, the front end of the pedal having an arc-shaped protrusion, and the first support leg and the second support leg being respectively welded to the two ribs.

[0005] In a preferred embodiment of the present invention, the rib is a spherical flat steel rib, and the length of the pedal is less than the length of the mounting rod.

[0006] As a preferred embodiment of the present invention, the mounting rod is a rectangular hollow steel section, the first support leg and the second support leg are both angle steel, the first support leg and the second support leg are both welded to the mounting rod, one end face of the first support leg is welded to one of the ribs, and one end face of the second support leg is welded to another of the ribs.

[0007] As a preferred embodiment of the present invention, a reinforcing elbow plate is welded to the bottom surface of the pedal, the reinforcing elbow plate extends along the width direction of the pedal, and the rear end of the reinforcing elbow plate is welded to the mounting rod.

[0008] As a preferred embodiment of the present invention, each step device is provided with at least two reinforcing elbow plates.

[0009] As a preferred embodiment of the present invention, the pedal is provided with a 5mm thick anti-slip pattern.

[0010] As a preferred embodiment of the present invention, the arc-shaped protrusion is formed by bending the front end of the pedal.

[0011] Compared with the prior art, the channel platform of the ship's outer plating according to an embodiment of the present invention has the following advantages:

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] like Figures 1 to 2As shown, a preferred embodiment of the present invention provides a passage platform for a ship's outer plating, comprising ribs 1 disposed on the outer plating 3 and a plurality of step devices 2 disposed between two adjacent ribs 1; each step device 2 includes a pedal 21, a first support leg 22, a second support leg 23, and a mounting rod 24. The first support leg 22 and the second support leg 23 are respectively connected to the left and right ends of the mounting rod 24. The pedal 21 is fixed to the top surface of the mounting rod 24. The front end of the pedal 21 is provided with an arc-shaped protrusion 211, which effectively prevents slippage when stepping on the edge and improves safety. The first support leg 22 and the second support leg 23 are respectively welded to the two ribs 1.

[0020] This invention utilizes the rib plate 1 on the outer plating 3 of the hull as the supporting structure for setting the step device 2, eliminating the need for direct welding of the outer plating 3, reducing the structural impact on the outer plating 3, and the overall structure of the step device 2 is simple and stable, effectively saving outfitting manufacturing and installation costs and reducing the overall weight of the ship outfitting, and the number and spacing of the step devices 2 can be adjusted according to actual needs, with high flexibility and strong applicability.

[0021] For example, the rib plate 1 is a ball flat steel rib plate 1, which ensures high overall structural strength of the channel platform. The length of the pedal 21 is less than the length of the mounting rod 24, which effectively avoids interference between the pedal 21 and the ball head 11 or other protruding structures of the ball flat steel rib plate 1.

[0022] For example, the mounting rod 24 is a rectangular hollow steel section, and the first support leg 22 and the second support leg 23 are both angle steel, which effectively enhances the structural strength of the step device 2. The first support leg 22 and the second support leg 23 are both welded to the mounting rod 24. One end face of the first support leg 22 is welded to one of the rib plates 1, and one end face of the second support leg 23 is welded to another of the rib plates 1, thereby improving the connection strength between the two rib plates 1 and the first support leg 22 and the second support leg 23.

[0023] For example, a triangular reinforcing elbow plate 25 is welded to the bottom surface of the pedal 21. The reinforcing elbow plate 25 extends along the width direction of the pedal 21, and the rear end of the reinforcing elbow plate 25 is welded to the mounting rod 24. Specifically, each step device 2 is provided with at least two reinforcing elbow plates 25 to improve the support effect of the pedal 21 and prevent the pedal 21 from deforming when stepped on.

[0024] Furthermore, the pedal 21 is provided with a 5mm thick anti-slip pattern to increase the anti-slip effect.

[0025] For example, the arc-shaped protrusion 211 is formed by bending the front end of the pedal 21. The upward protrusion and downward bending structure of the front end of the pedal 21 can improve the structural strength of the arc-shaped protrusion 211.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
