This cleaning device includes a gate-shaped girder member that is movable on a rail along the axis direction of an aircraft, a plurality of movable bodies that are movable horizontally or downwardly with respect to the girder member, and a movable body. It consists of a cleaning brush device attached to the tip side.

The cleaning operation in this cleaning device is performed by moving the girder member close to the aircraft along the rail and moving the girder member toward the aircraft by controlling a program that is preset in consideration of the model and cleaning conditions stored in a control device including a computer. and the brush device may be operated independently or in conjunction with each other.

However, in the case of equipment that cleans by traveling on rails as mentioned above, there is no particular problem as long as the relative positional relationship between the aircraft and the cleaning equipment is maintained accurately, but if the relative positional relationship between the two is If this is not maintained, the cleaning effect will be reduced and the control system will become complicated.

In other words, if the aircraft deviates from the predetermined position relative to the cleaning device, the cleaning effect will decrease because the aircraft surface has a complex curved shape, and the followability of the moving body and brush device will deteriorate. do.

In order to improve this cleaning effect, it is necessary to detect the relative position of the aircraft and the cleaning device using sensors, etc., and to modify the pre-stored cleaning pattern based on this detected value, which complicates the control system and operability. It has problems such as:

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic aircraft cleaning device that improves the cleaning effect by accurately maintaining the relative positional relationship between the aircraft and the cleaning device.

[Embodiments of the invention]

An embodiment of the apparatus of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing the overall configuration of an automatic cleaning device of the present invention, in which an aircraft 1 is moved by a tug (not shown) or the like and stopped at a cleaning work position. Next, a gate-shaped girder member 2 equipped with a cleaning device moves along the guide rails 3 and 3' to this cleaning work position. This girder member 2
Regarding the positioning relationship between the aircraft 1 and the aircraft 1, the aircraft 1 is positioned in advance by an automatic positioning device described later so that both are in a predetermined position. With the aircraft 1 and the girder member 2 positioned at predetermined positions in this manner, a large number of brush devices 4 movably supported by the girder member 2 via moving bodies are attached to the fuselage, main wings, etc. of the aircraft. Bring it closer and start cleaning. Then, when the cleaning work is completed, the girder member 2 is separated from the aircraft 1.

FIG. 2 is a diagram for explaining the automatic positioning means in the device of the present invention.
and motors 9 and 9' that drive the caterpillar type endless track belts 8 and 8' on which the main @6 and 6' are mounted.
, 9' is connected to the output shaft of the transmission 10.10' and the output shaft of the transmission 10.10' to convert the rotation speed of the endless track 4ik 8.
+8', driven wheels 11 and 12' that rotate according to the movement of the drive shafts 11 and 1bi, and the endless track bands 8 and 8';
A large number of detection mechanisms 1 for supporting the weight of the aircraft 1 placed on the track belt 8.8' and detecting the position of each axle 5, 6.6', such as server 1-0-ra 12, 12'; The main shafts 7, 7' of the aircraft 1 are placed thereon, and it is comprised of a truck 13 movable along rails 14 and the like. The endless track belt 8.8' and the trolley 13 are arranged perpendicular to the axis direction of the aircraft 1 so as to be able to be operated in forward and reverse directions, and are buried so that their upper surfaces coincide with the ground surface of the cleaning work area.

Figure 3 shows the support 1-roller 12゜12' of the detection mechanism.
In this cross-sectional view, the support rollers 12 and 12' include bearings 15 and 15' that rotatably support the support rollers 12 and 12' at both ends, and bearings 15 and 15' that rotatably support the support rollers 12 and 12'. The positions of the front wheel 5 and main shafts 6, 6' of 1 are as follows:
Load cell sensing via support roller 16.16
', etc.

Next, the operation of the automatic cleaning device of the present invention will be explained.

First, the aircraft 1 is moved by a tug and stops at a cleaning work site. In this state, as shown in FIG. 4, if the center position 17 of the aircraft 1 is deviated parallel to the predetermined center position 18 along the axis direction of the aircraft body that should be located in the cleaning device, the front wheels of the aircraft 1 5. The main wheels 6, 6' and 7, 7' are parked in a state shifted from the endless track belts 8, 8' of the automatic positioning means and the center position 18 of the bogie 13. At this time,
The most load is applied to the support rollers 12, 12' that detect the wheel position at the portions located directly below the front wheels 5 and the main wheels 6, 6'. Therefore, the respective motors 9, 9' are driven so that the load points of the support rollers 12, 12', on which the load is applied, are moved to symmetrical positions in the center of the endless track bands 8, 8'. Interlocking track belt 8
．． 8' moves in the same direction (in the direction of the arrow shown). Then, as shown in FIG. 5, when the center position 17 of the aircraft 1 coincides with the predetermined center position 18, the track belts 8, 8' and the trolley 13 stop, and the aircraft 1 is accurately positioned with respect to the cleaning device. .

By maintaining the relative positional relationship between the aircraft and the cleaning device with high accuracy in this manner, the ability of the cleaning device to follow the movable body and the brush device to the aircraft body improves, so that the cleaning effect can be improved.

Further, when the aircraft 1 is parked in a state where the center position 17 is inclined (inclination angle α) with respect to the predetermined center position 18 as shown in FIG. 6, the support rollers 1 that detect the wheel position
2 and 12' detect the positions of the front @5 and main wheels 6 and 6', and positioning is performed by moving the endless track; l+1'8.8' in the direction of the arrow shown.

FIG. 7 shows a block diagram for explaining the control system in the positioning means. After indexing the aircraft 1, when the start command device 19 issues a command signal to start positioning, the load detector supports 1- The load point position of the wheel is detected by the rollers 12, 12', and the position comparator 20 compares the displacement between the center position 17 of the aircraft 1 and a predetermined center position 18 of the cleaning device.

If the position comparator 20 detects the center position 17 and the center position 1,
8, a YES No. 43 is issued and the positioning is completed by the stop command device 21. Further, when the surface position is shifted, the position comparator 20 outputs the No.
This signal is further input to the position comparator 22. This position comparator 22 compares which direction the center position 17 of the aircraft 1 is located with respect to a predetermined center position 18, for example, to the left or right when viewed from the nose direction, and determines the center position as shown in FIG. 17 is shifted to the left of the center position 18, a YIES signal is issued, and when it is shifted to the right, a NO signal is issued. These signals cause the motor 9.9' to move towards the track belt 8.
, 8' are driven to move leftward or rightward.

In this way, the aircraft 1 is placed at a predetermined center position 18 of the cleaning work area.
Even if the index is shifted from the front wheel 5, the main shaft 6, 6'
By placing them on the endless track belts 8, 8', it is possible to automatically position them with high precision. At this time, the trolley 13 on which the main shaft 7.7' is mounted is configured to be able to easily move left and right along the rails 14 while supporting the load of the aircraft 1, and is adapted to the movements of the endless tracks q; pg, a'. By moving accordingly, positioning can be performed smoothly. Furthermore, since the front wheels 5 and the main shafts 6, 6' can be controlled by separate control systems, positioning can be performed in a short time.

As described above, with the apparatus of the present invention, it is possible to easily perform a cleaning operation on an aircraft positioned at a predetermined position in a cleaning work area.

FIG. 8 shows another embodiment of the automatic positioning means according to the present invention.

In FIG. 8, reference numeral 23 denotes a sensor for light, sound waves, etc. that detects the position of the aircraft 1 in a non-contact manner, and this sensor 23 drives the motors 9, 9' based on the detection signal to move the track belt 8 in the same manner as described above. , 8' are moved according to the positional deviation.

By configuring the detection means with sensors such as light and sound waves, the number of detection mechanisms can be reduced, and
This has the effect of facilitating adjustment operations.

In addition, as shown in the figure, the width of the track belt 8 on which the front axle 5 of the aircraft 1 with a small wheel load is placed is made larger than the width of the track belt 8' on which the main wheels 6.6' are placed. By forming such a configuration, it is possible to significantly expand the types of aircraft 1 to which the aircraft 1 can be applied.

Furthermore, the track belt 8°8' for correcting the position of the aircraft is replaced with a truck (not shown) similar to the truck 13, the relative position of the aircraft l and the cleaning device is detected by an optical sensor, etc., and the truck itself is It is also possible to drive in the left and right directions.

By using the trolley in this way, it is possible to downsize and simplify the entire device without embedding it in the floor of the washing machine.

〔Effect of the invention〕

According to the present invention, since the relative positional relationship between the aircraft and the cleaning device is maintained with high accuracy prior to the cleaning operation, the effectiveness of cleaning the aircraft can be significantly improved.
