[0041] Beneficially, it further includes a hydraulic system. The hydraulic system includes a hydraulic oil tank, a filter, a hydraulic pump and a distribution valve. The hydraulic system is used to drive the hydraulic motor I 19, the hydraulic motor II 15, the swing cylinder 14 and the adjusting cylinder 29 to work.

[0042] The working principle of the present invention:

[0043] In the initial state, the connecting buckle 27 is connected to the tow hook at the front end of the engineering vehicle. After adjusting the bearing beam 11 to be horizontal, the counterweight plate 16 and the engineering vehicle are fixed by bolts, so that the whole device has a stable working environment. The water distribution pipe 25 is connected to the water tank and the water pump, and the hydraulic system is connected. The plane passing through the axes of the roller shafts of the auxiliary roller brush 22 and the main roller brush 23 is defined as the working plane.

[0044] The engineering vehicle starts and slowly travels along the right side of the road. The hydraulic system starts, and the swing cylinder 14 and the hydraulic motor I 19 are controlled to work, so that the device is switched to the attached Figure 9 working state shown in the figure. The right rectangle in the figure is the highway guardrail, and the left rectangle is the engineering vehicle.

[0045] In the basic working mode, the rotating sleeve 32 and the fixed plate 21 are fixed by bolts, making the working plane parallel to the mounting plate 13. The hydraulic system controls the operation of the second hydraulic motor 15. The output shaft of the second hydraulic motor 15 drives the driving pulley 46 to rotate. The driving pulley 46 drives the main roller driving pulley 47 to rotate through the first synchronous belt 49. The main roller mounting shaft 36, the main roller driving pulley 51, the main roller connecting shaft 52, and the main roller brush 23 rotate together with the main roller driving pulley 47. The main roller driving pulley 51 drives the auxiliary roller driving pulley 48 to rotate through the second synchronous belt 50. The auxiliary roller mounting shaft 34 and the auxiliary roller driving pulley 45 rotate together with the auxiliary roller driving pulley 48. The auxiliary roller driving pulley 45 drives the tension pulley 56 and the driven pulley 40 to rotate through the third synchronous belt 58. The auxiliary roller connecting shaft 41 and the auxiliary roller brush 22 rotate together with the driven pulley 40. The water pump starts to make the nozzle 24 spray water. The rotation of the main roller brush 23 and the auxiliary roller brush 22 cleans the guardrail in contact with them.

[0046] In the advanced working mode, the fixing bolts of the rotating sleeve 32 and the fixed plate 21 are removed, and the rotating sleeve 32 returns to a state where it can rotate freely relative to the fixed plate 21. In this mode, the operation difficulty of the engineering vehicle is reduced. It is not necessary to keep the forward direction of the engineering vehicle completely parallel to the road guardrail, and the operator is allowed to slightly adjust the forward direction of the engineering vehicle. When the engineering vehicle moves slightly away from the road guardrail, the tension spring 31 pulls one end of the rotating sleeve 32, and the rotating sleeve 32 rotates relative to the fixed plate 21. The inclination angle of the tension spring 31 changes adaptively. The telescopic rod 37 rotates together with the rotating sleeve 32 and adaptively adjusts the elongation relative to the rotating sleeve 32. The telescopic rod 37 drives the connecting rod 38 and the slider 39 to move. The slider 39 slides along the slide rail 33. The driven pulley 40, the auxiliary roller connecting shaft 41, and the auxiliary roller brush 22 move together with the slider 39. During this process, the gas spring 57 works. The elastic force of the gas spring 57 is less than that of the tension spring 31. The gas spring 57 controls the limit block 54 to slide along the guide rail 53, keeping the limit block 54 away from the fixed block 59. The limit block 54 drives the moving shaft 55 and the tension pulley 56 to move together, keeping the third synchronous belt 58 always in a tensioned state. When the bristles of the main roller brush 23 do not contact the road guardrail, the auxiliary roller brush 22 can still maintain a certain contact with the road guardrail at all times, passively compensating for the angle of the working plane relative to the mounting plate 13, ensuring that the cleaning is not missed or interrupted, reducing the operation difficulty, and improving the cleaning quality.

[0047] Special working mode: When encountering a road turning area, according to the bending amplitude of the road, the hydraulic system is used to control the operation of the adjusting cylinder 29. The adjusting cylinder 29 controls the angle change of the mounting plate 13 relative to the moving seat 28, changing the working positions of the auxiliary roller brush 22 and the main roller brush 23 in the basic mode. When the road is about to turn right, the mounting plate 13 is controlled to swing, making the main roller brush 23 closer to the road guardrail relative to the auxiliary roller brush 22. After entering the curve, the angle of the working plane relative to the mounting plate 13 is actively compensated, and the contact degrees of the main roller brush 23 and the auxiliary roller brush 22 with the road guardrail are basically kept consistent; the principle for a left turn is the same, but the operation is opposite; it is ensured that during turning, both the auxiliary roller brush 22 and the main roller brush 23 have a certain contact with the road guardrail, and will not be damaged by excessive contact and extrusion.

[0048] It should be noted that the special working mode can be used in any one of the normal working mode or the advanced working mode. When based on the advanced working mode, when the auxiliary roller brush 22 and the main roller brush 23 are away from the road guardrail, the tension spring 31 becomes the normal working state. The plane determined by the axes of the auxiliary roller brush 22 and the main roller brush 23 at this time is the initial working plane, and the plane after the active compensation operation is the actual working plane.

[0049] In addition, this device is not limited to cleaning the guardrails on both sides of the road. By mirror - setting this device or installing the device at the rear of an engineering vehicle, it is possible to clean the median guardrail in the middle of the road.

[0050] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms in the present invention can be understood according to specific situations.

[0051] The above content is only an example and explanation of the structure of the present invention. Those skilled in the art of this technology can make various modifications, supplements, or use similar methods to replace the specific embodiments described, as long as they do not deviate from the structure of the invention or exceed the scope defined by the claims of the present invention, they should all fall within the protection scope of the present invention.
