Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning, and in particular relates to an aircraft surface cleaning device. Background Art

[0002] During the aircraft manufacturing process, a large number of workers will go up on the aircraft surface, inevitably causing contamination. After the workers complete their current onboard work, the aircraft surface needs to be cleaned as a whole before being delivered to downstream units. The existing method for treating aircraft surface contaminants is to manually wipe the aircraft surface with a cleaning wipe soaked in solvents such as acetone or gasoline, which is very time-consuming. Usually, the cleaner holds acetone in one hand and a cleaning wipe in the other, squeezing acetone from a container onto the cleaning wipe so that the acetone soaks the cleaning wipe. The cleaner then kneels on the aircraft surface and wipes the aircraft surface inch by inch with the cleaning wipe until the stains on the aircraft surface are completely removed. This cleaning method is not only time-consuming and labor-intensive, but also has poor cleaning quality. Given that large areas of aircraft surfaces are regular curved or flat surfaces, a cleaning device is needed to improve the efficiency and quality of aircraft surface cleaning. Utility Model Content

[0028] Example 1

[0029] Reference Figure 1 、 Figure 2 , a curved surface cleaning device, comprising:

[0030] The casing 1 has an opening at its lower end;

[0031] The cleaning unit includes two rollers 16 arranged opposite to each other and a belt 17 arranged between the rollers 16. A cleaning cloth 18 is provided on the outer surface of the belt. The rollers 16 are connected to a fixed shaft 12 fixed to the housing 1 through a rotating arm assembly 13. The rotating arm assembly 13 is rotatably connected to the fixed shaft 12. A tensioning assembly is provided between the housing 1 and the rotating arm assembly 13. The tensioning assembly applies a force to the rotating arm assembly 13 so that the belt 17 can always remain in a tensioned state. The rollers 16 can extend from the opening of the housing to the outside of the housing 1 in a free state;

[0032] A driving unit, which is used to drive the roller 16 to rotate along its rotation axis 15;

[0033] The liquid supply unit is used to provide cleaning liquid to the cleaning unit.

[0034] A cleaning device consisting of a cleaning unit, a driving unit, a liquid supply unit and a casing 1 is adopted. The liquid supply unit provides cleaning liquid for the cleaning unit. The driving unit drives the roller 16 to rotate along its rotating shaft 15. The cleaning unit adopts a rotatable roller 16 to cooperate with a tensioning assembly. When cleaning a convex curved surface, it can adapt to the shape of the curved surface, so that the cleaning cloth can deform with the shape of the curved surface, thereby being well adapted to the cleaning of the curved body surface, improving the efficiency and quality of cleaning, and reducing labor costs.

[0035] The housing 1 is used to position all components of the cleaning device and is a carrier for integrating the components.

[0036] The fixed shaft 12 is used to support the rotating arm assembly 13 so that the rotating arm assembly 13 can rotate at a certain angle around the fixed shaft 12 .

[0037] The arm assembly 13, located between the limiting beam 20 and the limiting block 21, supports the rotating shaft 15 of the roller 16 and provides a travel range. The arm assembly 13 includes two arms, each comprising two arm posts and an arm beam. One end of each arm post is connected to the ends of the fixed shaft 12, and the other end of each arm post is connected to the ends of the roller 16. The two arm posts are fixedly connected by the arm beam.

[0038] In some embodiments, reference Figure 3 The tensioning assembly includes a limiting beam 20 provided on the housing 1 and a limiting spring 11 provided between the limiting beam 20 and the rotating arm assembly 13 .

[0039] The tensioning assembly further includes a limit block 21 , which is arranged on the side of the rotating arm assembly away from the limit beam, and is used to limit the movement of the rotating arm assembly 13 toward the side away from the limit beam under the elastic force of the limit spring 11 .

[0040] The limit spring 11 is used to rebound the rotating arm assembly 13, and provides a movable stroke to the rotating arm assembly 13 when the cleaning device passes through the curved surface, so that the cleaning cloth 18 can be attached to the surface to be cleaned.

[0041] The limiting beam 20 is used to support the limiting spring 11 and limit the range of motion of the rotating arm assembly 13 .

[0042] When the cleaning device cleans the raised curved surface, the curved surface presses the cleaning cloth 18 upward. At this time, the two rollers 16 shrink inward, and the rotating arm assembly 13 rotates around the fixed axis 12. At the same time, the cleaning cloth 18 changes with the shape of the curved surface and fits the surface to be cleaned.

[0043] The use of a tensioning component enables the cleaning cloth to adapt to the shape of the curved surface when cleaning a convex curved surface, so that the cleaning cloth can deform along with the shape of the curved surface, thereby being well adapted to the cleaning of the curved body surface and improving the cleaning quality.

[0044] In some embodiments, both ends of the roller 16 are provided with roller 16 bosses for limiting the belt 17 .

[0045] The roller 16 boss is used to prevent the belt 17 from derailing during rotation.

[0046] In some embodiments, the surface of the drum 16 is provided with ribs protruding from the drum surface.

[0047] The surface of the drum 16 is provided with evenly distributed anti-skid ribs along the axial direction. The ribs are used to increase the friction between the drum 16 and the belt 17 and better drive the belt 17 to rotate.

[0048] In some embodiments, the cleaning cloth 18 is connected to the belt 17 using a Velcro connection.

[0049] Among them, the belt 17 is divided into an inner and outer side. The inner side of the belt is made of leather and is in contact with the roller 16; the outer side of the belt is sewn with Velcro hooks; the belt 17 rotates as the roller 16 rolls. The belt 17 is the carrier of the cleaning cloth 18. After the cleaning cloth 18 is disassembled and replaced, it is glued to the outer side of the belt through Velcro.

[0050] The cleaning cloth 18 is divided into an inner and outer side. The inner side of the cleaning cloth has Velcro fine hairs, which can be bonded with the Velcro hooks to achieve the bonding of the cleaning cloth 18 to the belt 17; the outer side of the cleaning cloth is used to clean the surface to be cleaned and is the component of the cleaning device that is in direct contact with the aircraft surface.

[0051] The cleaning cloth 18 is connected to the belt 17 by a Velcro connection, so that the cleaning cloth 18 can be cleaned and replaced more quickly.

[0052] In some embodiments, the liquid supply unit includes a solvent box 5, a liquid supply pump 7 and a liquid supply conduit 8. The solvent box 5 is arranged outside the casing, and the liquid supply conduit 8 is connected to the liquid supply pump 7 and arranged inside the casing.

[0053] The solvent box 5 is blue and translucent, with a capacity of 600 ml, and is used to hold cleaning fluid, which includes alcohol, acetone, gasoline, etc.

[0054] The solvent box 5 is provided with a solvent box blocking cover 6 for blocking the solvent injection port of the solvent box to prevent the cleaning liquid from splashing or pouring out during use of the cleaning device.

[0055] The liquid supply pump 7 is used to extract the cleaning liquid in the solvent box 5 and transport the cleaning liquid to the liquid supply conduit 8.

[0056] The liquid supply conduit 8 is used to transport the cleaning liquid and deliver the cleaning liquid to the nozzle 9. The liquid supply conduit 8 includes three evenly distributed branch pipes, and the ends of the branch pipes are used to install the nozzle 9.

[0057] In some embodiments, a plurality of nozzles 9 are provided on the liquid supply conduit 8 , and the nozzles 9 are arranged toward the location of the drum 16 .

[0058] The nozzle 9 is used for spraying the cleaning liquid in a mist form, so that the cleaning liquid can evenly soak the cleaning cloth 18 .

[0059] A plurality of nozzles 9 are provided on the liquid supply conduit 8 so that the cleaning liquid is evenly sprayed on the cleaning cloth 18, thereby improving the cleaning quality.

[0060] In some embodiments, the liquid supply unit includes two liquid supply conduits 8 , which are respectively disposed at the locations of the two rollers.

[0061] In some embodiments, the driving unit includes a driving motor 19 and a gear assembly 14 . The driving motor 19 drives the rotating shaft 15 of the drum 16 to rotate via the gear assembly 14 .

[0062] Among them, the drive motor 19 is connected to the power supply 10, and is used to drive the gear assembly 14 to rotate, providing rotational power for the drum 16; the drive motor 19 is fixedly connected to the rotating arm 13, and the drive motor 19 can be fixedly connected to the rotating arm 13 through a metal support arm, or the drive motor 19 is set on the rotating arm assembly 13; when the position of the drum 16 changes, the drive motor 19 moves with the rotating arm 13.

[0063] Reference Figure 4 The power supply 10 is connected to the driving motor 19 and the liquid supply pump 7 respectively, and is used to provide energy to the driving motor 19 and the liquid supply pump 7.

[0064] The gear assembly 14 is used to receive the torque of the driving motor 19 to drive the rotating shaft 15 of the roller 16 to rotate, thereby driving the roller 16 to rotate.

[0065] The rotating shaft 15 is used to transmit the rotational torque provided by the driving gear assembly 14 to rotate the drum 16.

[0066] In some embodiments, a handle 2 is provided on the housing 1 .

[0067] The handle 2 is used for the operator to hold and move the cleaning device so that the cleaning device can clean the regular curved surface. The handle 2 is provided with a drive motor switch button 3 and a liquid supply pump switch button 4.
