[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] In order to solve the technical problems in the prior art of using vertical ladders to reach maintenance platforms located at high places from sea level, the steep angle of the vertical ladders consumes a lot of physical strength of the operation and maintenance personnel, and there is a high risk of slipping and falling during the climbing process, the utility model provides a ladder mechanism suitable for maintenance platforms, which adopts a design that combines a vertical ladder with an inclined ladder, which can reduce the climbing difficulty of the operation and maintenance personnel.

[0028] See also Figures 1-8 , Figures 1-8This is a ladder mechanism suitable for a maintenance platform in one embodiment of the present invention. The maintenance platform is cylindrical as a whole. The ladder mechanism includes a vertical ladder 1, a conversion platform 2, a relay platform 3 and a support platform 4. The conversion platform 2 is fixedly connected to the side wall of the bottom end of the maintenance platform, and the support platform 4 is fixedly connected to the side wall of the top end of the maintenance platform. The relay platform 3 is fixedly connected to the side wall of the maintenance platform and is located between the conversion platform 2 and the support platform 4. The vertical ladder 1 is fixedly connected to the side wall of the maintenance platform and the upper end is connected to the conversion platform 2. The vertical ladder 1 extends vertically upward along the axis of the maintenance platform. An inclined ladder 5 is connected between the relay platform 3 and the conversion platform 2 and the support platform 4, and the inclined ladder 5 extends obliquely upward around the side wall of the maintenance platform.

[0029] It should be noted that due to the large fluctuations in tide levels at sea, the height of the ship's side will also change accordingly. Inclined ladders can be used to select the appropriate boarding position and angle according to different water levels and berthing heights, facilitating boarding from different directions and positions, thereby improving boarding flexibility and adaptability. Furthermore, the inclined ladder's inclination prevents liquids such as seawater and rainwater from accumulating on the ladder's surface, reducing the corrosive effects of moisture. The good ventilation also accelerates the drying of the ladder's surface, further reducing the risk of corrosion.

[0030] On the basis of the above solution, in order to improve the safety performance of the ladder mechanism, specifically, railings 6 are provided on the edges of the conversion platform 2 , the relay platform 3 , the support platform 4 and the two inclined ladders 5 .

[0031] It should be noted that the railing 6 is not limited to a specific structure. As long as it can protect the edges of the conversion platform 2, the relay platform 3, the support platform 4 and the two inclined ladders 5, no other limitations are made here.

[0032] In this specific embodiment, the railing 6 is a plurality of vertical bars 61 fixed at intervals on the edges of the conversion platform 2, the relay platform 3, the support platform 4 and the two inclined ladders 5, and a plurality of horizontal bars 62 connected between the plurality of vertical bars. The plurality of vertical bars and the plurality of horizontal bars form a mesh structure.

[0033] On the basis of the above solution, skirting boards 7 are further provided on the edges of the transfer platform 2 , the relay platform 3 , the support platform 4 and the two inclined ladders 5 and on the inner side of the railing 6 .

[0034] In this specific embodiment, the transfer platform 2, relay platform 3, and support platform 4 are all fixedly connected to the maintenance platform via a plurality of embedded parts 8. Specifically, the embedded parts 8 include an end embedded steel plate 81, an embedded steel plate 82, and embedded rods 83. One end of the plurality of embedded rods 83 is fixedly connected to the embedded steel plate 82, and the other ends of the plurality of embedded rods 83 are respectively fixedly connected to the end embedded steel plate 81. The end embedded steel plate 81 and the plurality of embedded rods 83 are fixedly installed in the maintenance platform, and the embedded steel plate 82 is located outside the maintenance platform.

[0035] It should be noted that the conversion platform 2 , the relay platform 3 and the support platform 4 all include a frame formed by welding I-beams, and a grid plate fixed on the frame, and one side of the frame is fixedly connected to the embedded steel plate 82 .

[0036] On the basis of the above solution, in order to improve the supporting strength of the relay platform 3 and the support platform 4, specifically, diagonal bracing rods 9 are further provided between the lower surfaces of the relay platform 3 and the support platform 4 and the maintenance platform.

[0037] Based on the above solution, to prevent collisions between ships and the vertical ladder 1, specifically, mooring assemblies 10 are provided on opposite sides of the vertical ladder 1, and the mooring assemblies 10 are fixedly connected to the foundation piles of the maintenance platform.

Handrails are provided on opposite sides of the vertical ladder 1. The handrails are located between the two mooring assemblies 10.

[0038] It should be noted that the anti-collision steel plate 101 has a strong structural strength, and the rubber fender 102 can absorb the kinetic energy of the ship collision, thereby preventing the vertical ladder 1 from being damaged by the ship collision.

[0039] In this embodiment, the inclined ladder 5 includes two side panels 51 and a plurality of step panels 52. The two side panels 51 extend upward along the outer side of the maintenance platform, and the plurality of step panels 52 are spaced apart between the two side panels 51.
