detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1-2,

The layout of the main electrical components of the utility model is shown in Figure 1. It includes a command input unit, a processing unit and a detection unit, and the command input unit and the detection unit are connected to the processing unit through a wiring harness;

The command input unit includes an operation box 1 in the cab;

Described processing unit comprises PLC, and PLC is installed in the central control box 3;

The detection unit includes an inner roller brush extension detection switch 4, a high-pressure water pump suction detection switch 7, a waterway ball valve opening detection switch 8, a clean water tank water level detection switch 9, a roller brush gap detection switch 13 and an outer roller brush swing detection switch 14,

PLC, voice alarm and other electrical components are installed in the central control box 3, which is placed behind the seat in the cab to facilitate wiring and inspection; the operation box 1 in the cab is equipped with necessary operation buttons and emergency stop switches And working status indicator light, etc., to indicate the working status of the whole system, which is convenient for on-site operation and can ensure safety. When you turn on the key switch for auxiliary engine start on the panel of the operation box, the power indicator light is on, and the auxiliary engine charging indicator light is on, indicating that the equipment is powered on, and each detection switch enters the detection state, and feeds back the signal to the PLC. The PLC compares the current feedback signal with the design signal. Determine which working status is met, and issue a voice reminder. After the auxiliary engine is started, the power indicator light is on and the auxiliary engine charging indicator light is off. At this time, the auxiliary engine has been idling and can be cleaned.

The cleaning operation of the system is divided into roller brush control and cleaning control. The roller brush control can be realized by operating the cross switch on the operation box. Operating two cross switches can realize eight actions: the roller brush rises, the roller brush descends, the roller brush The brush extends, the roller brush returns, the outer roller brush rotates, the outer roller brush returns, the outer roller brush extends, and the outer roller brush returns. By controlling the position of the roller brush, the vehicle is equipped with the conditions for cleaning operations.

After the guardrail cleaning vehicle drives to the working road section, bring the car close to the working surface, open the guide plate 10, turn on the warning light 15, and operate the two cross switches on the control box of the cab, so that the guardrail is in the middle position between the outer roller brush and the inner roller brush. The cleaning operation conditions are available, and the cleaning device is monitored in real time through the color display screen 11 and the camera 12 installed in the cab. Manually operate the rolling brush and the rolling brush stretches out, and after the proximity switch 4 that the rolling brush stretches out detects in place, the rolling brush stops stretching out, and at this moment, the swinging action of the outer rolling brush just allows execution. Operate the cross switch to swing the outer roller brush, the outer roller brush swings to the horizontal position, the proximity switch 14 of the outer roller brush swings detects the in-position signal, and at this time allows the outer roller brush to extend and return; operate the outer roller brush to extend, the outer roller brush Continue to stretch out in the horizontal position until the guardrail is placed in the middle of the inner and outer roller brushes, operate the cross switch to return the outer roller brush, and the outer roller brush returns to the original position. Now the gap between the inner and outer roller brushes is detected by the roller brush gap detection switch 13. After the roller brush is adjusted in place, the cleaning operation can be carried out. It is necessary to select the working mode in the operation box 1 of the cab: high pressure cleaning mode, low pressure cleaning mode, high and low pressure cleaning mode. When selecting the operation mode, first check whether there is water in the clean water tank through the water level detection switch 9 of the clean water tank, and open the detection switch 8 through the waterway ball valve to see whether the waterway ball valve is opened in place. If these two conditions are satisfied at the same time, it can be judged as an operational state. Secondly, in the high-pressure mode and the high-low pressure mode, it is necessary to detect whether the high-pressure water pump clutch is engaged through the high-pressure water pump pull-in detection switch 7; in the "high-pressure" mode, the high-pressure water pump works, and the four roller brushes rotate. Spray water to make the roller brush work with water. According to the thickness of the guardrail, operate the four-position rocker control switch of the "outer roller brush mechanism" to adjust the overlapping amount of inner and outer roller brush bristles. After the preparation is in place, according to the cleanliness of the guardrail, choose an appropriate speed and drive to start cleaning the guardrail. In "low pressure" mode, the high-pressure water pump is turned off, the four roller brushes rotate, and the two low-pressure water pumps work. At this time, the low-pressure nozzles spray water to the roller brushes, so that the roller brushes work with water. According to the thickness of the guardrail, operate the four-position rocker control switch of the "outer roller brush mechanism" to adjust the overlapping amount of inner and outer roller brush bristles. After the preparation is in place, according to the cleanliness of the guardrail, choose an appropriate speed and drive to start cleaning the guardrail. "High and low pressure" mode, the high-pressure water pump works, two low-pressure water pumps work, and the four roller brushes rotate. At this time, the high-pressure nozzle sprays water on the roller brushes, and the low-pressure nozzle sprays water on the roller brushes, so that the roller brushes work with water. According to the thickness of the guardrail, operate the four-position rocker control switch of the "outer roller brush mechanism" to adjust the overlapping amount of inner and outer roller brush bristles. After the preparation is in place, according to the cleanliness of the guardrail, choose the appropriate speed to drive to start cleaning the guardrail

The above is only the preferred implementation of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. Retouching should also be regarded as the protection of the utility model.
