Description

Technical Field

[0001] The utility model relates to the technical field of aircraft ground maintenance, in particular to a rain and snow shielding device for aircraft cabin doors during outfield maintenance. Background Art

[0002] Generally, the daily maintenance work of aircraft has two scenarios: maintenance on the apron and maintenance in the hangar. When it comes to engine and external tests, maintenance work needs to be arranged on the apron. When performing maintenance on the apron, a maintenance ladder is usually used to climb up. Common maintenance ladders are of a general frame structure and all have safety handrails. When closing the aircraft cabin door during rain or snow weather during apron maintenance, sometimes the maintenance ladder will interfere with the cabin door, resulting in the inability to close the cabin door. If the cabin door is not closed, rainwater will directly flow into the aircraft through the cabin door, causing aircraft line failures or equipment failures. If someone holds an umbrella to shield the rain for the aircraft cabin door, it will not only waste manpower and material resources, but also the umbrella cannot fit the fuselage completely, resulting in water leakage. If a customized maintenance ladder is made, the special maintenance ladder is only applicable to a certain aircraft model, with poor applicability, a long production cycle, high production costs, and low utilization rate.
