[0037] The working process of the de-icing guardrail cleaning vehicle of the present invention is as follows:

[0038] Step 1: The cleaning truck arrives at the designated cleaning location and starts the motor.

[0039] Step Two: The motor transmits power to the reducer via a coupling, the reducer transmits power to the steering box, and the steering box transmits power to the screw jack via a coupling. The screw jack drives the screw to rotate forward, and the screw and screw nut work together to move the top plate of the screw upward so that the roller brush device can cross the guardrail. After crossing the guardrail, the motor is stopped. At this time, the second hydraulic pump is started to drive the crossbeam boom device to extend. When the guardrail is in the middle position with the cleaning device, the second hydraulic pump stops working. Then the motor is started again to make the screw reverse. The crossbeam boom device connected to the top plate of the screw drives the roller brush device and the de-icing and drying device on the connecting plate to move downward. When the optimal cleaning position is reached, the motor stops.

[0040] Step 3: Start the first high-pressure steam generator. The first high-pressure steam generator sprays high-temperature saturated steam through the steam nozzle to de-ice the surface of the guardrail.

[0041] Step 4: Start the first hydraulic pump, so that the first and second roller brushes start rotating at a speed of 200 r / min. At the same time, start the high-pressure water pump, and the water spray pipe sprays the cleaning liquid onto both sides of the guardrail.

[0042] Step 5: Start the second high-pressure steam generator. The second high-pressure steam generator sprays high-temperature, dry air through steam nozzles to dry the surface of the guardrail, preventing any remaining water stains from refreezing and affecting the cleaning effect. While the cleaning and de-icing / drying devices are operating, the cleaning truck can move forward slowly to improve cleaning efficiency.

[0043] Step Six: Start the electric motor. The lead screw drives the lead screw top plate upward to its highest position. Start the second hydraulic pump to drive the crossbeam boom to extend and retract until the cleaning device and de-icing drying device are fully embedded in the vehicle body. Turn off the second hydraulic pump. The electric motor reverses direction, and the lead screw top plate moves downward to the initial cleaning position. Turn off the electric motor. The cleaning of the guardrail is complete. If the cleaning fluid or fuel is insufficient, the engine and electric motor can be turned off to stop the cleaning operation.

[0044] The present invention discloses a de-icing guardrail cleaning vehicle, which uses a lifting device, a crossbeam boom device, a cleaning device, and a de-icing and drying device to work together to de-ic, clean, and dry the guardrail, preventing the water stains from refreezing and improving the cleaning efficiency of the guardrail. After the work is completed, the cleaning device and the de-icing and drying device can be embedded in the vehicle body to save space.
