An operation panel of a high-pressure washing apparatus equipped with a tool, which is an operation panel body mounted in the vicinity of a large hose reel and a small hose reel, and has a large hose or small hose that ejects washing water pumped by a water pump. An operation panel body equipped with a large / small hose changeover switch for switching to a hose and a rotation speed adjustment handle for a large hose reel, and a removable panel attached to the operation panel body. A con apparatus, is intended to include winding a large hose from the large hose reels, and stopping and feeding can switch and a remote control device including a speed increasing and reducing the switch of the engine.

  According to the operation panel of the high-pressure washing apparatus of the present invention, the hose for ejecting the washing water pumped by the water pump by the large / small hose changeover switch in the operation panel body can be switched in advance to the large hose or the small hose. After that, the operator can operate the hose reel drive switch of the remote control device at a position away from the operation panel main body to wind, stop or feed the large hose reel. In addition, since the operation panel main body is provided with a large hose reel rotation speed adjustment handle, the operator adjusts the rotation speed of the large hose reel in advance using the operation panel main body, and the hose reel drive switch of the remote control device. The large hose reel can be wound, stopped or extended at a rotational speed adjusted in advance, but the remote control device acceleration / deceleration switch is operated at a position away from the operation panel body to By increasing or decreasing the rotational speed, the rotational speed of the large hose reel can be adjusted within a certain range. In addition, since the remote control device is equipped with an engine speed increasing / decelerating switch, when the operator drives the water pump to eject the washing water from the large hose or small hose, the remote control device is remote from the operation panel body. By operating the acceleration / deceleration switch of the device to increase / decrease the engine speed, the injection amount from the injection device at the tip of the hose can be adjusted.

  According to the present invention, the hose to be used for the cleaning work is selected in advance by the large / small hose changeover switch of the operation panel body, and the operator operates the hose reel drive switch of the remote control device at a position away from the operation panel body. Thus, the large hose reel can be wound, stopped or fed out, and the high pressure washing device can be operated even at a position away from the operation panel body. The rotational speed of the large hose reel can be adjusted within a certain range by increasing / decreasing the rotational speed. In addition, the operator adjusts the rotation speed of the large hose reel in advance with the operation panel body, operates the hose reel drive switch of the remote control device at a position away from the operation panel body, and operates the large hose with the rotation speed adjusted in advance. The reel can be taken up, stopped or fed out. In addition, when the operator drives the water pump to eject cleaning water from the large hose or small hose, the operator operates the acceleration / deceleration switch on the remote control device at a position away from the operation panel body to increase or decrease the engine speed. By doing so, it becomes possible to adjust the injection amount from the injection device at the tip of the hose.

An operator can operate the large and small hose reel drive switch 33 of the remote control device 4b at a position away from the operation panel main body 4a to wind, stop or feed out the large hose reel 2 or the small hose reel 3. The high-pressure washing apparatus 1 can be operated even at a position away from the main body 4a.

  In the high-pressure washing apparatus 1, the operator adjusts the rotation speed of the large hose reel 2 or the small hose reel 3 in advance with the large / small hose reel rotation speed adjustment handle 21 of the operation panel main body 4a, and from the operation panel main body 4a. It is possible to operate the large and small hose reel drive switch 33 of the remote control device 4b at a distant position, and to feed out or wind up the large hose reel 2 or the small hose reel 3 at a rotation speed adjusted in advance. The rotational speed of the large hose reel 2 can be adjusted within a certain range by operating the engine rotation speed control switch 32 and increasing or decreasing the engine speed.

  In the embodiment of the present invention, the large hose reel 2 or the small hose reel 3 can be fed out or wound up, but only the large hose reel 2 may be fed out or wound up.

  Moreover, in this high-pressure washing apparatus 1, when the operator drives the water pump 13 to eject the washing water from the large hose 2a or the small hose 3a, the engine rotation of the remote control device 4b is away from the operation panel body 4a. The speed control switch 32 can be operated to increase or decrease the engine speed. When the engine speed control switch 32 is switched to the speed increasing side, the T relay is actuated first, the T relay contact is closed a little later, the R13 relay is energized, the a contact R13 is closed, and the motor M is rotated forward. The engine speed increases. When the engine upper limit rotational speed is detected, the a contact switch 52 is activated, the R12 relay is energized, the b contact R12 is opened, the motor M is stopped, the engine is held at the upper limit rotational speed, and the remote control device. The engine high-speed lamp 36 of 4b lights up and the engine speed cannot be increased any further. Next, when the engine rotation speed control switch 32 is switched to the deceleration side, the motor M rotates in the reverse direction and the engine decelerates. When the idling speed is detected, the b contact switch 51 is activated, the a contact R11 of the R11 relay is opened, the motor M is stopped, and the engine maintains idling rotation.

  In addition, although the high-pressure washing apparatus 1 in the embodiment of the present invention is mounted on the chassis 10 of the high-pressure washing vehicle, the high-pressure washing apparatus is loaded on the cargo handling vehicle, and the high-pressure washing apparatus is loaded and unloaded to the sewage treatment plant or the like together with the frame. It can also be used as a stationary facility.
