It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] The following is combined with Figure 1-9The present invention describes a specific embodiment of a guardrail cleaning device, comprising a load-bearing beam 11, an mounting plate 13 connected to the load-bearing beam 11 via a first folding arm 17 and a second folding arm 20, a fixing plate 21 fixedly connected to the mounting plate 13, a main roller brush 23 rotatably mounted on the fixing plate 21, and a secondary roller brush 22 rotatably mounted on the fixing plate 21; the device employs a mode in which two roller brushes work simultaneously to avoid omissions in cleaning by a single roller brush.

[0027] One end of the second folding arm 20 is connected to the first folding arm 17, and the other end of the second folding arm 20 is fixedly provided with a movable seat 28. A swing seat 30 is fixedly provided on one side of the mounting plate 13. The movable seat 28 and the swing seat 30 are hinged together. An adjusting cylinder 29 is provided between the movable seat 28 and the swing seat 30. An adjusting seat 43 is fixedly connected to the mounting plate 13 on one side of the swing seat 30. The cylinder of the adjusting cylinder 29 is hinged to the movable seat 28, and the piston rod of the adjusting cylinder 29 is hinged to the adjusting seat 43. The adjusting cylinder 29 controls the main roller brush 23 and the auxiliary roller brush 22 to actively change their tilt angle relative to the guardrail. It actively compensates for the posture of the main roller brush 23 and the auxiliary roller brush 22. Corresponding to the special working mode of this equipment, the purpose is to facilitate the cleaning of the curved part of the guardrail when the road turns, and to ensure that the two roller brushes can have a suitable contact area with the guardrail at the same time, so as to avoid cleaning omissions caused by untimely turning or damage to the roller brushes by squeezing.

[0028] In another embodiment of this utility model, a slide rail 33 is fixedly provided on one side of the fixed plate 21, and a slider 39 is slidably provided on the slide rail 33. The auxiliary roller brush 22 is detachably mounted on the slider 39. The fixed plate 21 and the slider 39 are connected by a tension spring 31, which passively keeps the auxiliary roller brush 22 close to the guardrail. Passive compensation is to reduce the difficulty of operation. Corresponding to the advanced working mode of this equipment, it allows the operator to deviate slightly from the set working trajectory without causing serious consequences to the cleaning work, thereby improving the cleaning quality and efficiency.

[0029] Advantageously, a connecting buckle 27 is fixedly provided on the load-bearing beam 11, and the connecting buckle 27 is connected to the engineering vehicle. A counterweight plate 16, fixedly connected to the load-bearing beam 11, is provided on one side of the connecting buckle 27 and is also connected to the engineering vehicle. A mounting base 12 is fixedly provided at the end of the load-bearing beam 11 away from the counterweight plate 16. A fixing base 26, fixedly connected to the load-bearing beam 11, is provided on one side of the mounting base 12. One end of the folding arm 17 is hinged to the fixing base 26. A swing cylinder 14 is provided between the load-bearing beam 11 and the folding arm 17. The cylinder of the swing cylinder 14 is hinged to the mounting base 12, and the piston rod of the swing cylinder 14 is hinged to the folding arm 17. Considering the working radius after the equipment is unfolded, the equipment is installed at one end of the load-bearing beam 11. The counterweight plate 16 ensures that the forces on both ends of the load-bearing beam are kept as balanced as possible, avoiding wear and deformation of the tow hook of the engineering vehicle during long-term operation.

[0030] Advantageously, a connecting seat 18 is fixedly provided at the end of the folding arm 17 away from the fixed seat 26, and the end of the folding arm 20 away from the movable seat 28 is hinged to the connecting seat 18. A hydraulic motor 19 is detachably installed on one side of the connecting seat 18, and the hydraulic motor 19 is used to drive the folding arm 20 to rotate relative to the connecting seat 18. The hydraulic motor 19 can drive the folding arm 20 to fold at a large angle. After folding, the end effector does not obstruct the driver's view of the construction vehicle, ensuring that the end effector roller brush can be quickly positioned without interfering with the operator's normal driving of the construction vehicle.

[0031] Advantageously, a hydraulic motor 215 is detachably mounted on one side of the fixed plate 21. A drive pulley 46 is fixedly mounted on the output shaft of the hydraulic motor 21. The drive pulley 46 drives the main roller drive pulley 47 via a synchronous belt 49. The main roller drive pulley 47 is fixedly mounted on the main roller mounting shaft 36, which is rotatably connected to the fixed plate 21. The main roller mounting shaft 36 passes through the fixed plate 21, and one end of the main roller mounting shaft 36 is connected to the main roller brush 23 via a main roller connecting shaft 52. The hydraulic motor 215 drives the main roller brush 23 to rotate and clean the guardrail. The driving method uses a combination of synchronous belt and pulley, but is not limited to a single synchronous belt drive. This equipment does not require high transmission precision; it only needs to ensure that the roller brush rotation achieves the cleaning effect on the guardrail. Therefore, most transmission structures used to transmit torque can be used as long as the structure is reasonable.

[0032] Advantageously, a main roller drive pulley 51 is fixedly mounted on one side of the main roller connecting shaft 52 on the main roller mounting shaft 36. The main roller drive pulley 51 drives the auxiliary roller drive pulley 48 via a second synchronous belt 50. The auxiliary roller drive pulley 48 is fixedly mounted on the auxiliary roller mounting shaft 34, which is rotatably connected to the fixed plate 21. The auxiliary roller mounting shaft 34 passes through the fixed plate 21. An auxiliary roller drive pulley 45 is fixedly mounted at the end of the auxiliary roller mounting shaft 34 away from the second hydraulic motor 15. The auxiliary roller drive pulley 45 drives the driven pulley 40 via a third synchronous belt 58. The driven pulley 40 is fixedly mounted on the auxiliary roller connecting shaft 41. One end of the auxiliary roller connecting shaft 41 is rotatably connected to the slider 39, and the end of the auxiliary roller connecting shaft 41 away from the slider 39 is fixedly connected to the auxiliary roller brush 22. The auxiliary roller brush 22 obtains power from the main roller brush 23 via the synchronous belt, and the transmission method is not limited to synchronous belt transmission.

[0033] Advantageously, a fixing block 59 is fixedly provided at the end of the fixing plate 21 away from the hydraulic motor 15. A guide rail 53 fixedly connected to the fixing plate 21 is provided on one side of the fixing block 59. A limiting block 54 is slidably provided on the guide rail 53. A gas spring 57 is provided between the limiting block 54 and the fixing block 59. The two ends of the gas spring 57 are fixedly connected to the fixing block 59 and the limiting block 54, respectively. A moving shaft 55 is rotatably provided at the end of the limiting block 54 away from the hydraulic motor 15. A tension pulley 56 is fixedly provided at the end of the moving shaft 55 away from the limiting block 54. The tension pulley 56, the auxiliary roller drive pulley 45, and the driven pulley 40 are all driven by the synchronous belt 58. The main roller brush 23 adopts a fixed working position, while the auxiliary roller brush 22 adopts a floating working position. The tensioning structure related to the gas spring 57 ensures that the auxiliary roller brush 22 can maintain the transmission relationship during the floating process.

[0034] Advantageously, a fixing strip 44 is fixedly provided on the side of the fixing plate 21 away from the auxiliary roller brush 22. The slide rail 33 and the fixing strip 44 are connected by bolts. Multiple mounting posts 35 are provided around the periphery of the fixing plate 21 for mounting the outer casing. The main roller connecting shaft 52 and the auxiliary roller connecting shaft 41 pass through the outer casing and are respectively connected to the outer casing via sealed bearings. The outer casing is not shown in the diagram; its shape is sufficient to accommodate the installation of internal parts. The casing has a sealing effect and is waterproof. Furthermore, the oil circuit, pipeline, and electrical circuit structure of this equipment are not shown in the diagram. The folding arm has an internal hollow structure to meet installation requirements; proper installation is sufficient.

[0035] Advantageously, a rotating sleeve 32 is provided on one side of the fixing strip 44. The rotating sleeve 32 is rotatably connected to the fixing plate 21. Both ends of the tension spring 31 are fixedly connected to the hydraulic motor 15 and one end of the rotating sleeve 32, respectively. A telescopic rod 37 is slidably provided at the end of the rotating sleeve 32 away from the tension spring 31. A connecting rod 38 is fixedly provided at one end of the telescopic rod 37. The end of the connecting rod 38 away from the telescopic rod 37 is fixedly connected to the slider 39. The elastic force of the tension spring 31 is much greater than that of the gas spring 57, so there is no need to worry about the tension of the gas spring 57 causing reverse interference to the position of the auxiliary roller brush 22.

[0036] Advantageously, a pipe clamp 42 is fixedly provided at the end of the mounting plate 13 away from the fixing plate 21. A water distribution pipe 25 is detachably installed on the pipe clamp 42. A nozzle 24 is fixedly provided on the side of the water distribution pipe 25 near the main roller brush 23. The part of the water distribution pipe 25 that connects to the engineering vehicle is not shown in the figure. This equipment does not limit the material and shape of the water pipe, as long as it meets the water supply requirements.

[0037] Advantageously, it also includes a hydraulic system comprising a hydraulic tank, a filter, a hydraulic pump, and a distribution valve, the hydraulic system being used to drive the hydraulic motor 19, the hydraulic motor 15, the swing cylinder 14, and the regulating cylinder 29.

[0038] Working principle of this utility model:

[0039] In the initial state, the connecting buckle 27 is connected to the hook at the front of the engineering vehicle. After adjusting the load-bearing beam 11 to be level, the counterweight plate 16 and the engineering vehicle are fixed with bolts to make the equipment have a stable working environment. The water distribution pipe 25 is connected to the water tank and water pump, and the hydraulic system is connected. The plane through which the axes of the auxiliary roller brush 22 and the main roller brush 23 pass is defined as the working plane.

[0040] The engineering vehicle starts and slowly moves along the right side of the road. The hydraulic system activates, controlling the swing cylinder 14 and hydraulic motor 19 to work, switching the equipment to auxiliary mode. Figure 9 The diagram shows the working conditions, with the right rectangle representing the highway guardrail and the left rectangle representing the engineering vehicle.

[0041] In the basic working mode, the rotating sleeve 32 is fixed to the fixed plate 21 with bolts, making the working plane parallel to the mounting plate 13. The hydraulic system controls the hydraulic motor 15 to work. The output shaft of the hydraulic motor 15 drives the drive pulley 46 to rotate. The drive pulley 46 drives the main roller drive pulley 47 to rotate through the synchronous belt 49. The main roller mounting shaft 36, the main roller drive pulley 51, the main roller connecting shaft 52, and the main roller brush 23 rotate together with the main roller drive pulley 47. The main roller drive pulley 51 drives the auxiliary roller drive pulley 48 to rotate through the synchronous belt 50. The auxiliary roller mounting shaft 34 and the auxiliary roller drive pulley 45 rotate together with the auxiliary roller drive pulley 48. The auxiliary roller drive pulley 45 drives the tension pulley 56 and the driven pulley 40 to rotate through the 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, causing the nozzle 24 to spray water. The main roller brush 23 and the auxiliary roller brush 22 rotate, cleaning the guardrail they come into contact with.

[0042] In the advanced working mode, the fixing bolts between the rotating sleeve 32 and the fixed plate 21 are removed, restoring the rotating sleeve 32 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, as it is not necessary to keep the engineering vehicle's forward direction completely parallel to the road guardrail, allowing the operator to make small adjustments to the engineering vehicle's forward direction. When the engineering vehicle moves slightly away from the road guardrail, the tension spring 31 pulls one end of the rotating sleeve 32, causing the rotating sleeve 32 to rotate relative to the fixed plate 21. The tilt angle of the tension spring 31 changes adaptively, and the telescopic rod 37 changes its angle along with the rotating sleeve 32, adaptively adjusting its extension relative to the rotating sleeve 32. The telescopic rod 37 drives the connecting rod 38 and the slider 39. As the main roller brush 23 moves, the slider 39 slides along the slide rail 33, and 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, so that the limit block 54 is kept away from the fixed block 59. The limit block 54 drives the moving shaft 55 and the tension pulley 56 to move together, so that the synchronous belt 38 is always kept taut. When the bristles of the main roller brush 23 are not in contact with 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 difficulty of operation, and improving the cleaning quality.

[0043] In a special working mode, when encountering a road curve, the hydraulic system controls the adjustment cylinder 29 to work according to the curvature of the road. The adjustment cylinder 29 controls the angle of the mounting plate 13 relative to the moving seat 28, changing the working position 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, so that the main roller brush 23 is 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 degree between the main roller brush 23 and the auxiliary roller brush 22 and the road guardrail is basically consistent. The principle is the same for left turns, but the operation is reversed. This ensures that when turning, both the auxiliary roller brush 22 and the main roller brush 23 have a certain contact with the road guardrail, and that excessive contact will not cause the auxiliary roller brush 22 and the main roller brush 23 to be squeezed and damaged.

[0044] It should be noted that the special working mode can be used in either the normal working mode or the advanced working mode. When the advanced working mode is used as the basis, when the auxiliary roller brush 22 and the main roller brush 23 are far away from the road guardrail, the tension spring 31 becomes the normal working state. The plane determined by the axis 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.

[0045] In addition, this equipment is not limited to cleaning guardrails on both sides of the road. By mirroring the equipment or installing it at the rear of engineering vehicles, it can also clean the median guardrails on the road.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of this utility model, they should all fall within the protection scope of this utility model.
