Description

Technical Field

[0001] This utility model belongs to the field of aircraft maintenance technology and relates to a spraying device for aircraft surface coating. Background Technology

[0002] Aircraft maintenance refers to a series of activities involving the inspection, repair, adjustment, and replacement of parts and components of an aircraft to maintain its safe, reliable, and efficient operation. This includes regular maintenance checks, fault diagnosis and repair, parts replacement, and performance upgrades. Aircraft maintenance work strictly follows the manufacturer's maintenance manual and the regulations of aviation regulatory agencies to ensure that the aircraft meets all safety and operational standards. After prolonged use or an accident, structural components of an aircraft may develop cracks or damage. Following structural repairs, the repaired areas need to be repainted to ensure consistency in appearance and protective performance with the rest of the aircraft.

[0003] For example, patent CN217594911U discloses a spraying device for aircraft surface coating, including a movable base, a paint tank, a support plate, a spray gun, a replenishment mechanism, and a pushing mechanism. The replenishment mechanism includes a paint pump and a paint replenishment pipeline, and the pushing mechanism includes an ultrasonic level gauge, a main control unit, and an electric push rod. When repainting the paint chipped surface of an aircraft, the operator can move the paint tank and the spray gun to the position to be repainted, and the spray gun will perform the repainting. If the paint in the spray gun runs out, the paint pump can replenish the paint in the paint tank to the spray gun to facilitate continuous spraying. When the amount of paint in the paint tank is low, the electric push rod can push the paint tank to tilt, so that the paint gathers on one side of the paint pump, so that the paint pump can extract the remaining paint and avoid wasting paint.

[0004] However, the device does not have a component for cleaning the spray gun piping assembly. After the device is finished using it, the spray gun and its piping assembly need to be disassembled for cleaning, which makes the maintenance of the equipment by the staff quite cumbersome.
