The rotary brush 35 supported by the nut member 32 is rotationally driven by an air motor 36 with a speed controller. The rotary brush 35 is a compression spring 21.
b makes elastic contact with the object to be cleaned. When the movable rod 14 reaches the upper limit position, the pair of front and rear rotary brushes 35, 35 comes into contact with the irradiation prism L4 in the front and rear of the guide lamp L at a substantially right angle.

The air motor 36 is connected to the generator-equipped compressor Cp on the work vehicle T. In addition, the support frame 21
A nozzle 37 for jetting air and a nozzle 38 for jetting washing water are attached side by side in a. Each of the nozzles 37, 38 has a horizontal plate 1 when the movable rod 14 is at the lower limit position.
The washing machine body 1 is arranged so as to face the notch portion 16a of 6 and thus face the irradiation prism L4 in a state where the washing machine body 1 is mounted on the guide lamp L. The nozzles 37 and 38 also communicate with the compressor Cp with a generator and the water tank Tw so as to blow air or water onto the irradiation prism L4.

As shown in FIGS. 1 and 2, on the platform of the work vehicle T, a compressor Cp with a generator and a water tank T are installed.
w, an auxiliary tank Ta, a control panel Ct, and a storage cover Cv are provided. The storage cover Cv is for storing the washing machine body 1 when the work vehicle T is moved to the work site, and includes a clamp C1 that fixes the frame body 2. In addition, the control power for work etc. is the compressor Cp with a generator.
It depends on the power generated. Further, the Be of the balancer is operated by the operation box Bx in the work vehicle T.

In this cleaning device, the storage cover Cv
The washing machine main body 1 is housed therein, fixed by the clamp C1, moved to the runway which is the work site by the work vehicle T, and the work vehicle T is stopped at the work site. Turn on the operation switch of the device,
The balancer Be is operated to take out the washing machine main body 1 from the storage cover Cv. On the driver's seat, the operator puts his or her hand out of the window and holds the handle to perform a fine adjustment operation for positioning the main body 1 of the washing machine, and the positioning member 15 is arranged on the guide light L. Engaging protrusion 17
When the horizontal plate 16 comes into contact with the upper surface of the guide light L by being fitted into the cap nut N of the guide light L, the balancer Be is locked and the cleaning operation is automatically started.

In the positioned state, the movable rod 14 is at the lower limit position with respect to the support member 11 due to its own weight and the compression spring 19, and the nozzles 37 and 38 are the irradiation prism L4 of the guide light L.
Suitable for In the cleaning work, first, air is blown by the nozzle 37 to blow off dust and dust on the surface of the irradiation prism L4. Next, the nozzle 38 irradiates water with the prism L4.
Spray on the surface. Next, when the rotary actuator 5 and below are lowered by the air cylinder 4, the compression spring 1
While compressing 9, the support member 11 descends relatively to the movable rod 14, and along with this, the sliding rod 13 descends along with the horizontal rod 12 along the arm member 20, so that the arm member 2
The distance between 0 and 20 is narrowed, and the rotary brush 35 contacts the irradiation prism L4. In this state, the rotary brush 35
Is rotationally driven by the air motor 36 to polish the irradiation prism L4. This rotary brush 35 is vertically pressed by the rotary actuator 5 substantially at the center of the irradiation prism L4, and reciprocates in the angular range of 18 ° forward and backward and rotates while reversing. The rotary actuator 5 is swing-controlled while detecting the turning position by the proximity switch 9. Next, the rotary actuator 5 and below are raised by the air cylinder 4, and the rotary brush 2
After separating 4 from the irradiation prism L4, water is blown off with a nozzle 38 to remove dirt, and water is blown off with air at a nozzle 37. When the above cleaning operation is completed, the lock of the balancer Be is released, so the balancer Be is operated to raise the cleaning machine body 1 and move the work vehicle T to the adjacent guide light L. Then, similarly to the above, the guide lights L are successively washed by the work vehicle T.

In the case where a guide light L having a different size or shape depending on the installation location due to a curve or the like is provided in the connecting path of the airplane, the rotary brush 35 is correspondingly provided.
The mounting position of is changed by the mounting member 22. Mounting member 22
Selects the adjustment hole 23a of the connecting piece 23 as appropriate so that the mounting position of the rotary brush 35 can be adjusted.
Can be adjusted in the extension direction. Further, by changing the position of the stop bolt 28 within the elongated hole 27 of the frame plate 26, the relative angle of the rotary brush 35 together with the adjusting plate 29 can be adjusted. Further, when the screw shaft 31 is rotated, the nut member 32 is displaced on the shaft, and when the set bolt 28 is tightened, the locking pin 33 is pressed against the concave portion 34 and fixed, so that the rotary brush 3
The position of 5 in the direction of the screw shaft 31 can be adjusted.

When the last work of cleaning the guide light L is completed,
The balancer Be is operated to store the washing machine main body 1 in the storage cover Cv and fix it with the clamp C1, and the switch on the control panel Ct is turned off to finish the work. In this embodiment, the cleaning device is applied to the guide light buried in the traveling route of the aircraft, but the approach light indicating the route of the aircraft on the ground, the stop light indicating the stop position, or the terminal indicating the end position of the route. It can be widely applied to similar lights embedded in airport facilities such as lights.

[0020]

As described above, according to the present invention, since the brush mounting position can be changed, even if the size of the guide light or the position of the irradiation prism is changed according to the traveling course of the aircraft, the position can be changed. It is possible to deal with the problem, it is possible to surely remove the dirt, and the working efficiency is improved.
