[0033] Specifically, by starting the hydraulic rod 7, the ladder frame 4 is driven by the hydraulic rod 7, and the coordinated rotation of the rotating column 3 and the rotating member 8 enables the ladder frame 4 to lift or rotate downward with the rotating column 3 as the axis, thereby facilitating the adjustment of the angle of the ladder frame 4, and thus achieving the effect of initially adjusting the angle of the gangway. By starting the servo motor 9, the rotating column 10 is driven to rotate, so that the two connecting plates 11 complete the corresponding rotation. The gangway can be assisted in adjustment by changing the angle of the connecting plate 11 according to different usage situations, avoiding the situation where the angle of the gangway cannot be well adjusted, thereby significantly increasing the flexibility of the gangway and improving the practicality of the gangway.

[0034] Referring to Figure 1 , Figure 2 and Figure 5 , the installation mechanism 2 includes two fixing members 201.

[0035] Specifically, by aligning and engaging the fixing member 201 with the installation groove 204, the initial fixation of the connection shell 1 at the front side position of the fixing seat 203 can be achieved. By rotating the rocker plate 206, the threaded column 205 generates a threaded displacement, and then is threadedly connected to the threaded groove 202 inside the fixing member 201, so that the fixing member 201 and the threaded column 205 are fixed together, thus completing the fixed installation process of the connection shell 1, improving the convenience during the installation of the gangway, improving the overall installation efficiency, and effectively reducing the labor cost of the operator due to the simplification of the installation process.

[0039] Specifically, the use of the gangway ladder is facilitated through the handrail 15, stepping on the air when using the gangway ladder is prevented through the filter plate 18, and at the same time the generation of accumulated water is prevented, and the servo motor 9 is facilitated to be protected through the protective shell 17.

[0040] Working principle: When starting to use, by starting the hydraulic rod 7, the ladder frame 4 is driven, and then the rotation of the rotating column 3 and the rotating member 8 causes the ladder frame 4 to lift or rotate downward with the rotating column 3 as the axis, so as to facilitate the adjustment of the angle of the ladder frame 4, achieving the effect of initially adjusting the angle of the gangway ladder. Furthermore, by starting the servo motor 9 to drive the rotating column 10 to rotate, the two connecting plates 11 are rotated, so that the gangway ladder can complete the auxiliary adjustment of the ladder frame 4 through the angle change of the connecting plates 11 according to different situations, thus avoiding the situation where the angle of the gangway ladder cannot be adjusted well, increasing the flexibility of the gangway ladder, and improving the practicability of the gangway ladder;
