Description

Technical Field

[0001] The invention relates to the technical field of ship construction, in particular to a channel platform of a ship outer plate. Background Art

[0002] In ship design, liquid compartments and sewage outboard ports are usually arranged on the left and right sides of the bottom of the hull. These places are places that crew members need to visit frequently, and the outer plate line of the bottom of the hull is usually a complex curved surface. Anti-skid strips can be installed on the outer plate structure with a gentle slope to facilitate the passage of crew members; but some ship types have narrow lines and the outer plate position is very steep. After installing anti-skid strips on the outer plate, it cannot meet the normal passage needs. Usually, it is necessary to use angle steel to build a channel platform. Since the installation stage of the channel platform built by angle steel is later than the installation stage of anti-skid strips, direct welding on the outer plate structure is not allowed in principle. This makes the platform built by angle steel very complicated and consumes a lot of material, which in turn increases the overall weight of the ship's outfitting, which is not conducive to the economy of ship design.

[0020] The present invention utilizes the ribs 1 on the hull outer plate 3 as the supporting structure for setting the step device 2. There is no need to directly perform welding operations on the hull outer plate 3, thereby reducing the structural impact on the hull outer plate 3. Moreover, the overall structure of the step device 2 is simple and stable, which effectively saves the cost of outfitting production and installation and reduces the overall weight of the ship outfitting. The number and spacing of the step device 2 can be adjusted according to actual needs, and it has high flexibility and strong applicability.

[0021] Exemplarily, the rib plate 1 is a bulb-flat steel rib plate 1, which ensures that the overall structural strength of the channel platform is high. 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 bulb-flat steel rib plate 1.

[0022] Exemplarily, the mounting rod 24 is a rectangular hollow steel section, and the first supporting leg 22 and the second supporting leg 23 are both angle steels, which effectively enhance the structural strength of the stepping device 2. The first supporting leg 22 and the second supporting leg 23 are both welded to the mounting rod 24, and one end face of the first supporting leg 22 is welded to one of the rib plates 1, and one end face of the second supporting leg 23 is welded to one of the rib plates 1, thereby improving the connection strength between the two rib plates 1 and the first supporting leg 22 and the second supporting leg 23.

[0023] Exemplarily, a triangular reinforcing elbow plate 25 is welded to the bottom surface of the pedal 21, and the reinforcing elbow plate 25 is extended along the width direction of the pedal 21. The rear end of the reinforcing elbow plate 25 is welded to the mounting rod 24; specifically, each stepping device 2 is provided with at least two reinforcing elbow plates 25 to improve the supporting effect of the pedal 21 and prevent the pedal 21 from being deformed by being stepped on.

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

[0025] Exemplarily, the arc-shaped protrusion 211 is formed by bending the front end of the pedal 21 , and the front end of the pedal 21 is an upwardly protruding and downwardly bent structure, which can improve the structural strength of the arc-shaped protrusion 211 .

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
