Description

Technical Field

[0001] This utility model relates to the technical field of multi-functional aircraft refueling connector repair and cleaning device, and particularly to a multi-functional aircraft refueling connector repair and cleaning device. Background Technology

[0002] Aircraft refueling connectors must be removed, cleaned, inspected, and have their seals replaced within the specified time or upon discovery of any abnormalities. Traditional methods have the following drawbacks: they require two people to work together, one holding the connector and the other tightening it; residual oil in the hose can easily splash onto arms or onto the floor, posing high environmental and occupational health risks; after removal, the hose lacks fixed support, and residual fuel can spray out directly during secondary depressurization, resulting in fuel waste and the risk of slipping; and the lack of a dedicated work surface at the maintenance site leads to haphazard placement of parts, increasing the risk of quality issues such as "missed or incorrect refueling." Utility Model Content

[0014] Beneficial effects of this utility model

[0015] This utility model provides a multi-functional aircraft refueling connector maintenance and cleaning device:

[0016] 1. Integrated functions and convenient operation: The mobile device integrates the functional modules required for maintenance and cleaning, such as oil connection, joint docking, and oil pipe fixing, to achieve "one-stop" operation. This avoids the trouble of needing multiple scattered tools in traditional operations and significantly improves maintenance efficiency.

[0017] 2. Environmentally friendly and safe, preventing pollution: The fuel collection tank and its unique sloping bottom design effectively collect residual fuel that drips or is discharged during maintenance and cleaning, and centrally recovers it through the bottom outlet. This not only avoids fuel pollution of the apron environment but also eliminates safety hazards, meeting the high environmental and safety standards of modern aircraft maintenance.

[0018] 3. Automatic sealing to prevent evaporation and leakage: The docking assembly uses a spring-driven automatic closing valve. When the aircraft refueling connector disengages from the docking interface, the valve automatically closes under the action of the spring, effectively preventing the evaporation of residual fuel vapors in the fuel tank and preventing foreign objects from entering the docking channel, thus ensuring the cleanliness and sealing of the device.

[0019] 4. Wide adaptability and reliable fixation: The oil pipe fixing component adopts a hinged upper and lower semi-circular clamp structure, which can be easily opened and closed. It is suitable for oil pipes of different diameters and is fast and reliable to lock through buckles, ensuring that the oil pipe is firmly fixed during maintenance and will not swing at will.

[0020] 5. Flexible movement and rational layout: The design of the mobile trolley, wheels, and handles allows the entire device to be easily moved within the apron or maintenance workshop, offering high mobility. Furthermore, the added maintenance box provides dedicated storage space for tools and parts, keeping the work site organized and further improving work efficiency. Attached Figure Description
