Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an aircraft engine cleaning device.

(Prior Art) Conventionally, aircraft cleaning has generally been carried out manually by workers, and for this reason, cleaning large aircraft such as jumbo jets is a very laborious process that requires about 20 workers to spend 3 to 4 hours. This is a task that requires a lot of effort and time.

Therefore, in order to mechanize the cleaning work so that it can be completed in a short time of about one hour by a small number of workers, an engine washer as disclosed in Japanese Patent Application Laid-open No. 116298/1983 has been developed.

(Problems to be Solved by the Invention) However, the conventional cleaning method described above uses a spray nozzle type, and does not provide a mechanical cleaning method with higher cleaning effects.

Considering the reason why mechanical cleaning methods for engine cleaning are difficult, the diameter of brushes used in cleaning equipment is generally 100 mm.
Qmua has a lot, so the minimum ground clearance is 500-70
It is extremely difficult to clean the area around the engine of a large aircraft such as 011jI, and in the end, operators have no choice but to manually clean the area, which has the drawback of poor machine cleaning efficiency.

This invention was devised in view of the above-mentioned conventional problems.
The purpose is to provide an aircraft engine cleaning device that can mechanize and streamline the cleaning work of aircraft engines, shorten the working time, and improve the machine cleaning rate.

(Means for Solving the Problem) The engine cleaning device of the present invention is provided by laying a ground rail extending in the longitudinal direction of the wing engine on the floor corresponding to the position directly below the wing engine of an aircraft carried in; A traveling truck is arranged, and an auxiliary truck is mounted on the traveling truck, which is horizontally movable at right angles to the traveling direction,
Further, an auxiliary trolley that is movable in the vertical direction is provided on the auxiliary trolley, and the auxiliary trolley that is movable in the vertical direction is provided with a link unit that is swung by a driving means and a flat brush that is attached to the tip of the link unit. It is characterized by being

(Example) The present invention will be explained below based on embodiments shown in the drawings.

In this specification, for convenience, the horizontal plane direction parallel to the axis of the aircraft is defined as the X direction, and the horizontal plane direction perpendicular to the X direction and the vertical plane direction perpendicular to the X direction are defined as the Y direction and the Z direction, respectively. The running carts that move in the direction and the Z direction are respectively referred to as an X cart and a Y cart.

On the floor in a position corresponding to the lower part of the main wing of the imported aircraft,
A rail 1 is arranged at almost the same angle as the main wing attachment angle of the aircraft when viewed from the plane, and a rail 2 continuous in the X direction is arranged on the floor 2 corresponding to the position directly below the engine.

The number of traveling carts 3, which run on rails 1 with XYX wheels 4 during standby and run on rails 2-H with X wheels 5 during cleaning, are arranged in the same number as the wing engines of the aircraft to be cleaned. A horizontal rail 6 is arranged inside the traveling carriage 3, and four Y carriages 8, 9 supported by the horizontal rail 6 via a plurality of guide rollers 7 are mounted.

Of these, the two Y bogies 8°8 arranged diagonally are for cleaning the lower part of the wing engine, and are provided with two vertical rails 10 extending upward. A Z-carriage 11 that moves up and down is mounted, and the Z-carriage 11
A lifting lift 12 is attached to the top. A brush drive motor 13 and a link unit 14 that is swung by the motor 13 and extends toward the inside of the traveling carriage 3 are provided on the lift 12.
There are four flat brushes 15, 16, 17.
18 is installed.

In addition, the remaining two 9゜9 of the four Y bogies are for cleaning the upper part of the wing engine, and each Y bogie 9'' has a mount 9.
a is provided, and an elevating lift 19 is provided on the pedestal 9a.
is installed. Similar to the Y-truck 8, a brush drive motor 20 and a link unit 21 are provided on the lifting lift 19, and three flat brushes 22, 23, and 24 are attached to the tip of the link unit 21. .

Below, the surroundings of the aforementioned link unit 14.21 are shown in Figure 4.
This will be explained based on FIG.

FIG. 4 shows the link unit 14 supporting the flat brushes 15, 16, 17, 18 for cleaning the lower part of the wing engine from the central part, and shows the shaft 2 of the brush actuating motor 13.
One end of a crank 28 is pivotally connected to an eccentric shaft 26 fixed to the bracket 32.
The bell crank 30 is pivotally supported at the lower end of the bell crank 30. The upper end of an arm 33 is pivotally attached to the other end of the bell crank 300, and the tips of two cranks 35 and 36 pivotally supported by a bracket 39 are pivotally attached to this arm 33. The other ends of the cranks 35 and 36 are connected to a small frame 53 that is pivotally supported by the large frame 44.
The upper end of 4 is the piston rod 4 of the hydraulic cylinder 42.
6. Supported at the tip. A bracket 47 and spring cases 48 and 49 are attached to the large frame 44, and the upper ends of the spring cases 48 and 49 have flat brushes of 16° and 17°.
is connected to.

Figure 5 shows flat brushes 22, 23 and 24 that clean the upper part of the wing engine and the pylon (the part that supports the engine, also called engine strut).
This figure shows a link unit 21 that supports the link unit 21, and has almost the same configuration as the link unit 14 described above. That is, an eccentric shaft 57 fixed to the shaft 56 of the brush-operated motor 20 and the lower end of a bell crank 60 are connected via a crank 59, and the upper end of the bell crank 60 is pivotally connected to an arm 64. 64 has a small 7L/-mu 7
Two arms 66 and 67 are pivotally connected to each other. The tip of the small frame 72 is connected to the central portion of the dog frame 77, and the lower end of the dog frame 77 is supported by the tip of the piston rod 79 of the hydraulic cylinder 75. The large frame 77 has a bracket 80 and a spring case 81.
82 is fixed, the tip of each spring case 81.82 is connected to a flat brush 23.24, respectively, and the bracket 80 pivotally supports the flat brushes 23 (22), 24.

Therefore, according to the link unit 14, the rotational motion of the eccentric shaft 26 is changed into a reciprocating motion by the crank 28, and the bell crank 30. Arm 33. Flat brushes 15, 16 through cranks 35, 36.

17.18 can be swung.

Further, according to the link unit, the rotational movement of the eccentric shaft 57 is changed into a reciprocating movement by the crank 59, and the arm 64
．． Flat brushes 22, 23 via levers 66, 67
．． 24 can be swung.

Moreover, according to the flat brush 24, a portion of the corner between the main wing and the pylon, and between the pylon and the engine can be reliably cleaned.

The connection between the flat brush and the pusher is achieved by attaching a coil spring 91 to a shaft 90 as shown in FIGS. 6 to 8, fixing one end of the coil spring 91 to one bracket 88, and fixing the other end to the other bracket 89. Fixed to. Bracket 88
．． 89 supports flat brushes 86 and 87, and as shown in Fig. 7, the flat brushes 86 and 87 are normally positioned at an angle of approximately 90° so that they face each other, and as shown in Fig. 8. As shown, when cleaning, the flat brushes are pressed against the engine, opening the angle between them.

(Effects of the Invention) The present invention has the above-described configuration. According to the present invention, it is possible to easily and reliably perform mechanical cleaning of a wing engine, which was previously impossible. Labor saving and safety improvement can be achieved.
