Then, when the dirt on the jump rear 27 is lifted by the cleaning agent, clean water is jetted from the spray nozzle 13 to wash away the cleaning agent, and the waste liquid of the cleaning agent and clean water is collected in the waste liquid receiver seat 21 and used for cleaning. sent to tank 9,
Furthermore, since the cleaning section is covered by the enclosure sheet 91, the cleaning agent and clean water will not be scattered around. In addition, even when jetting clean water to wash away the cleaning agent, it is preferable to rotate the spray nozzle 13 around the jump rear 27 as described above, and if necessary, the oscillating mechanism 51
The rack 45 may be operated by the drive unit 29.
The distance between the spray nozzle 13 and the jump rear 27 may be changed by sliding in the direction of arrow B.

The above cleaning work is displayed on the monitor television 87 by the surveillance camera 85, so the operator 89 can operate the drive unit 29 and the swinging mechanism 51 while looking at the monitor screen.

Then, after a predetermined period of time has elapsed, the spouting of fresh water is stopped and the cleaning status of the jump rear 27 is checked on the monitor screen, and if dirt is noticeable in some areas, the cleaning work can be continued focusing on that area. When it is determined that the cleaning with the cleaning agent and fresh water is satisfactory, the swing motor 35 of the drive unit 29 moves the hot air jet nozzle 33 to the jump rear 27.
The jump rear 27 may be dried by blowing warm air onto the jump rear 27 while rotating it around the jump rear 27 and, if necessary, operating the swinging mechanism 51.

When the operator 89 determines that the drying work is sufficient based on the monitor screen, the operator 89 stops blowing out the hot air, lowers the lifting device 17, and moves the traveling platform 1 to the next work location. The same cleaning operation may be performed again. After the cleaning work for all jump rears is completed, as shown in Fig. 2, the lifting device 17 is stored, the enclosure seat 91 is removed from the waste liquid receiver seat 21, and the flexible hose for the cleaning agent and the warm air hose are removed. The flexible hoses may be removed from the spray nozzle 13 etc. and stored in the hose holder.

As described above, according to this embodiment, when cleaning the Jump Rear 27, there is no need to perform large-scale temporary construction work, construct scaffolding, or suspend the Jump Rear 27, as in the past, and the process from installing the device to completing the cleaning process is eliminated. Since cleaning up can be completed in a short time, the work time can be significantly shortened compared to conventional methods, and there is no disruption to the business hours of the installation location. In addition, the work is safe because there is no need to work at heights. However, since there is no need to lower the Jump rear 27, the risk of damage to the lighting equipment is avoided, and since there is no need to manually wipe each crystal glass component, labor costs, which have a high cost ratio, can be reduced. This resulted in a significant reduction.

In the above embodiment, a pantograph mechanism was used as the elevating device 17, but a cylinder mechanism or the like may be used instead of such a mechanism.
