The high-pressure water manifold 217 is an integral unit of two vertically upstanding manifolds 217a and 217b, and can be moved up and down by a lifting mechanism 226A. The high-pressure water spray nozzles 222 provided in the manifolds 217a and 217b are staggered in the vertical direction along the wall surface at regular intervals. After adjusting the height of these high-pressure water injection nozzles 222 with an elevating mechanism 226A as necessary, the vehicle 201 can be moved and moved along the wall surface to clean the wall surface over a wide range. ing.

  The detergent manifold 209 is a single vertically erected manifold and can be moved up and down by a lifting mechanism 226B. Further, the detergent spray nozzles 214 provided in the detergent manifold 209 are arranged at equal intervals in the vertical direction along the wall surface, and the height of the detergent spray nozzles 214 is adjusted by the lifting mechanism 226B as necessary. By running the vehicle 201 and moving it along the wall surface, the detergent can be sprayed onto the wall surface prior to the high-pressure water, and the wall surface can be cleaned over a wide range.

The lifting mechanisms 226A and 226B include a telescopic cylinder type equipped with another hydraulic cylinder mechanism in the hydraulic cylinder mechanism and capable of extending in multiple stages, and a pantograph type by combining a pantograph and a hydraulic cylinder. A type lifting mechanism may be employed.
Although not shown, the vehicle 201 is additionally equipped with a low-pressure water injection mechanism that suppresses absorption of mist generated by spraying high-pressure water onto the wall surface by injecting low-pressure water so as to cover the periphery of the mist. It is also good. In this case, since the fog can be prevented from spreading outside the cleaning work place by covering with low-pressure water, the influence of the cleaning work on other places can be reduced as much as possible.
Further, as shown in FIG. 6, a wiping sponge 250 (wiping mechanism) for wiping the wall surface W after cleaning by jetting high-pressure water HW may be additionally mounted on the vehicle 201. In this case, the wiping sponge 250 makes it possible to remove the wetting of the wall surface W and remaining dirt reliably and in a short time.

The implementation of the cleaning work by the wall cleaning vehicle of the present embodiment having the above-described configuration will be described below.
First, the vehicle 101 is brought close to the vicinity of the wall surface to be cleaned, and in this state, the detergent manifold 209 and the high-pressure water manifold 217 are raised to a predetermined height by the lifting mechanisms 226A and 226B by the operator's operation, and shown in FIG. As described above, the high-pressure water spray nozzles 222 and the detergent spray nozzles 214 are opposed to the wall surface W. In this state, the detergent supply pump 208 and the high-pressure water supply pump 216 are activated by the operator's operation. Then, the detergent CL is jetted from each detergent jet nozzle 214 and applied evenly to the wall surface W. Subsequently, the high pressure water HW sprayed from each high pressure water spray nozzle 222 is washed away along with the detergent CL while the vehicle 201 is traveling. In such a cleaning operation, after the height of cleaning of the wall surface W is adjusted by the lifting operation by the lifting mechanisms 226A and 226B, the vehicle 201 is moved little by little. In this way, cleaning is performed over a wide range of the wall surface W.

  The wall cleaning vehicle of the present embodiment having the above-described configuration includes a high-pressure water injection nozzle 222 that injects high-pressure water HW sent from the water supply tank 215 via the high-pressure water supply pump 216 to the wall surface W, The structure provided with the cleaning apparatus 203 which has the raising / lowering mechanism 226A which raises / lowers this high pressure water injection nozzle 222 was employ | adopted. According to this configuration, since the wall surface W can be cleaned in a non-contact manner, it is possible to suppress damage to the wall surface W to be cleaned as much as possible. In addition, since the dirt on the wall surface W is removed by the water pressure of the high-pressure water HW, it is not necessary to brush the wall surface W as in the prior art, and it is possible to clean without requiring a great deal of labor by the operator.

  Further, the wall cleaning vehicle of the present embodiment has a plurality of high-pressure water injection nozzles 222 arranged in the vertical direction along the wall surface W, and the high-pressure water injection nozzles 222 are moved along the wall surface W by traveling of the vehicle 201. The structure which cleans the wall surface W was adopted. According to this configuration, the vertical cleaning range of the wall surface W is covered by the high-pressure water injection nozzles 222 arranged in the vertical direction and the vertical stroke thereof, and the horizontal cleaning range of the wall surface W is Since it is covered by traveling, it is possible to cover a very wide cleaning range of the wall surface W.

Moreover, the wall-cleaning vehicle of this Embodiment employ | adopts the structure provided with the detergent injection mechanism 204 which injects the detergent CL with respect to the wall surface W before injecting the high pressure water HW in the cleaning apparatus 203. FIG. According to this configuration, the wall surface W can be more effectively cleaned by spraying the detergent CL onto the wall surface W.
Moreover, the wall cleaning vehicle of this Embodiment employ | adopted the structure provided with the said heater which heats up the high pressure water HW in the cleaning apparatus 203 until it reaches the high pressure water injection nozzle 222. According to this configuration, since the high-pressure water HW sprayed on the wall surface W becomes warm water, the wall surface W can be more effectively cleaned as compared with the case of cold water.

  Further, in the wall cleaning vehicle of the present embodiment, each of the high-pressure water injection nozzles 222 is provided with the rotor that swirls the jet of the high-pressure water HW that is injected onto the wall surface W and diffuses the range covered by the high-pressure water. Adopted the configuration. According to this configuration, since the high-pressure water HW is diffused by the rotation of the rotor and can be sprayed over a wide range of the wall surface W, a wide range of cleaning can be performed with a small amount of the high-pressure water HW. It has become.

  In addition, although the wall cleaning vehicle of 1st reference embodiment, 2nd reference embodiment, and one embodiment of the above description is suitable for the cleaning work of the translucent sound insulation wall of a highway, for example, it is not restricted to this, Of course, the present invention may be applied to cleaning work in other places such as wall surface cleaning.
