However, the traditional curing method of concrete anti-collision guardrails is to cover them with geotextiles and spray them manually. This method relies on manual labor, which not only consumes a lot of time and manpower, but also the curing quality is easily affected by the operator's awareness and work attitude. Workers will inevitably be negligent or tired during the operation, so the spraying will be untimely, uneven, or even missed during the curing process, resulting in uneven growth of the strength of the concrete anti-collision guardrail and fine cracks on the concrete surface.

[0056] SS001, Width adjustment: Start the adjustment motor 5 to drive the first bidirectional screw 6 to rotate, so that the moving blocks 7 on both sides move synchronously toward or in the opposite direction along the limit rod 9, and drive the moving plate 8 and the water outlet nozzle 3 to adjust to the position matching the width of the concrete anti-collision guardrail;

[0057] SS002, height and angle adjustment: start the telescopic motor 11, drive the second bidirectional screw 12 to rotate, move the adjustment block 13 and drive the lifting plate 15 and the water outlet nozzle 3 to rise and fall to the preset height through the sliding of the rotating plate 14 and the slider 16 in the slide groove 17; synchronously rotate the adjusting screw 22 to adjust the inclination angle of the water outlet nozzle 3;

[0058] SS003, spray maintenance: The water supply of the water storage tank 2 is started through the control device 25, and the water is transported to the water outlet nozzle 3 through the hose for spraying. At the same time, the walking wheel 29 drives the trolley to move along the guardrail. The sensor 30 and the camera 31 monitor the humidity of the maintenance surface in real time, and feedback is given to adjust the spray parameters or the travel speed of the trolley.

[0059] Working principle: When the self-propelled spray curing trolley for concrete anti-collision guardrail is working, the water stored in the water tank 2 is transported to the water outlet nozzle 3 through a hose to provide a water source for spray curing. The adjustment mechanism drives the first bidirectional screw 6 to rotate through the adjustment motor 5 in the driving assembly, so that the moving block 7 drives the moving plate 8 to move, thereby adjusting the distance between the water outlet nozzles 3 to adapt to concrete anti-collision guardrails of different widths. The limit rod 9 limits the movement of the moving block 7 to ensure the stability of the movement. The telescopic mechanism drives the water outlet nozzle 3 to adjust its height through the movement of the moving assembly to meet the maintenance needs of different heights.

[0060] The telescopic motor 11 in the telescopic mechanism drives the second bidirectional screw 12 to rotate, so that the adjustment block 13 drives the rotating plate 14 and the lifting plate 15 in the linkage assembly to move, thereby adjusting the height of the water outlet nozzle 3. The slider 16 in the linkage assembly slides in the slide groove 17 to ensure the smooth lifting and lowering of the lifting plate 15. The first telescopic rod 18 connects the support block 10 and the lifting plate 15 to further enhance the stability of the lifting. The sliding assembly inside the lifting plate 15 rolls in the groove 19 through the roller 20 to reduce friction and make the lifting smoother. The adjusting screw 22 in the tilting assembly is connected to the water outlet nozzle 3 through a bearing, and the tilt angle of the water outlet nozzle 3 can be adjusted to adapt to guardrails of different shapes.

[0061] The roller 20 in the sliding assembly rolls in the inner cavity of the groove 19 of the lifting plate 15, making the lifting plate 15 more stable and smooth during the lifting process, reducing the friction between the lifting plate 15 and the support block 10, and extending the service life of the equipment. The adjusting screw 22 in the tilting assembly rotates in the support frame 21, pushing or pulling the water outlet nozzle 3 connected thereto, so that it can be tilted and adjusted at a small angle around the hinge connected to the support frame 21 to adapt to concrete anti-collision guardrails of different shapes or inclinations. The second telescopic rod 24 is installed between the support frame 21 and the water outlet nozzle 3. When the water outlet nozzle 3 is tilted and adjusted, the second telescopic rod 24 is telescoped accordingly, further enhancing the stability of the water outlet nozzle 3 during the tilt adjustment process. During the spraying maintenance process, the water supply of the water tank 2 is started through the control device 25, and the water is transported to the water outlet nozzle 3 through the hose for spraying. At the same time, the walking wheel 29 drives the trolley to move along the guardrail, so that the nozzle can evenly spray the entire guardrail surface. During this process, the sensor 30 and the camera 31 monitor the humidity of the curing surface in real time and feed the data back to the control device 25. The control device 25 adjusts the spray parameters or the travel speed of the trolley according to the feedback information to ensure that the concrete anti-collision guardrail is fully and evenly cured.

The solar panel 28 is installed on the top of the protection frame 1 to convert solar energy into electrical energy, providing partial or full power support for the electrical equipment of the entire trolley, which is energy-saving and environmentally friendly. The running wheel 29 is installed at the bottom of the adjustment frame 4, so that the entire spray curing trolley can move smoothly on the concrete anti-collision guardrail, which is convenient for spray curing operations on guardrails at different positions.
