Description

Technical Field

[0001] The utility model relates to the technical field of aircraft cleaning equipment, in particular to a laser cleaning device for cleaning the surface of an aircraft. Background Art

[0002] Aircraft need to be stripped of paint for maintenance every five years or so between flights to ensure the reliability of the aircraft. However, the paint stripping method currently used not only pollutes the environment and damages the health of workers, but is also expensive. In order to overcome the disadvantages of this method, a laser cleaning device is used to clean the aircraft surface. The cleaning requirements can be met while consuming only electrical energy, which is not only environmentally friendly but also saves money.

[0003] For example, the Chinese patent (patent publication number): CN215236467U proposes a laser cleaning device for cleaning the surface of an aircraft, including a base, a steering wheel fixedly installed on the left side of the lower surface of the base, the steering wheel is movably connected to one side of the rotating base of the steering platform through a connecting rod, the top of the rotating shaft of the steering platform is movably sleeved with the lower surface of the top of the inner cavity of the base, and a baffle is fixedly installed on the rotating shaft of the steering platform. The utility model uses the coordination arrangement between the steering wheel, the steering platform, the push rod, the traveling wheel and the traveling motor to enable the device to move the traveling wheel through the traveling motor, thereby enabling the device to move forward quickly, and at the same time, the steering platform is driven to rotate through the push rod, thereby enabling the steering wheel to move, so that the device can be adjusted in direction. Since the device moves mechanically, no human push is required, thereby saving the physical strength of the staff and realizing the function of quickly reaching the designated position.

[0004] However, when the above patent is used to clean the higher parts of the aircraft surface, since the laser cleaning head cannot be lifted vertically, there may be problems of insufficient height or inability to make corresponding adjustments after lifting. In addition, the laser cleaning head cannot be rotated, so when cleaning in the horizontal direction, the single cleaning area is small.
