Description
Technical Field
[0001] This utility model relates to the field of highway guardrail cleaning technology, and in particular to a guardrail cleaning device for highway maintenance. Background Technology
[0002] With the rapid development of urban construction and road and bridge construction in my country, guardrails, as an important traffic infrastructure, not only play a role in maintaining good traffic order, improving traffic safety and effectively reducing the incidence of traffic accidents, but also in beautifying the city.
[0003] Traditional guardrail cleaning equipment can only clean the guardrails. After cleaning, the water stains on the surface may be blown away by the wind and dust will be re-adsorbed on the surface. In addition, when encountering guardrails of different shapes, the water output of the nozzle must be adjusted after adjusting the height of the cleaning roller, which makes the process cumbersome.
[0004] In view of this, this paper studies and improves the existing problems to provide a guardrail cleaning device for highway maintenance. The device has a reasonable structural design, high stability, and can be used in various aspects. The aim is to solve the problems and improve the practical value through this technology. Utility Model Content
[0005] This utility model uses a first cleaning roller at the front end to clean the guardrail. After cleaning, water stains will remain on the surface of the guardrail. If the wind blows dust onto the surface of the guardrail, it may adhere to the surface. Therefore, after the first cleaning roller finishes cleaning, the second cleaning roller at the back end will wipe the cleaned area dry, thereby removing the water stains on the surface and preventing dust from adhering to the surface, thus realizing a guardrail cleaning device for highway maintenance.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a guardrail cleaning device for highway maintenance, comprising a fixed plate, a connecting block for improving overall stability fixedly connected to one side of the fixed plate, a height-adjustable connecting frame provided at the upper end of the fixed plate, a motor A for driving the connecting frame at the upper end, a threaded rod connected to the output end of the motor A, a motor B for rotation fixedly connected to both sides of the motor A, a rotating shaft for transmission connected to the lower end of the motor B, a first cleaning roller for cleaning fixedly connected to the lower end of the rotating shaft, a second cleaning roller for wiping provided on one side of the first cleaning roller, a connecting rod A for connection fixedly connected to the upper surface of the connecting block, water inlet pipes for transmission provided on both sides of the connecting rod A, a nozzle fixedly connected to the output end of the water inlet pipe, a gear for control provided on one side of the nozzle, a connecting shaft fixedly connected to the shaft center of one end of the gear, a valve for controlling the water volume fixedly connected to the end of the connecting shaft away from the gear, a connecting rod B provided on one side of the gear, and a toothed hole for meshing with the gear provided at the lower end of the connecting rod B.
[0007] Preferably, the fixing plate is provided in two sets, and the two sets of fixing plates are connected by connecting blocks. The connecting blocks are provided in three sets, and each set is connected to the fixing plate at both ends. The connecting frame is fixed to the upper end of the fixing plate by connecting to the threaded rod, and the number of connecting frames is two sets.
[0008] Preferably, the motor A is connected to the threaded rod, and there are two sets of motor A. Both sets of motor A are fixedly connected to the center of the upper end of the connecting frame. The threaded rod passes through the center of the fixed plate and is threadedly connected to the fixed plate. There are two sets of connecting frames, and motor B is provided at both ends, for a total of four sets.
[0009] Preferably, the first cleaning roller is rotated by the rotating shaft of the motor B, and the first cleaning roller is located at the front end of the equipment. The second cleaning roller is located at the rear end of the equipment, and is connected to the motor B through the rotating shaft and is also driven to rotate by the motor B.
[0010] Preferably, the connecting rod A is connected to the middle set of three sets of connecting blocks, and its other end is connected to the transport vehicle. The water inlet pipe is provided with two sets on both sides of the connecting rod A, with the end near the nozzle extending through the connecting block to the lower end. The nozzle is set at an in-box angle, and both sets are close to the center.
[0011] Preferably, the gear is fixedly connected to one side of the water inlet pipe via a connecting shaft, and the water inlet pipe extends through the outer wall of the water inlet pipe to the inside. The valve rotates inside the water inlet pipe by the rotation of the gear, and the outer diameter of the valve is slightly smaller than the inner diameter of the water inlet pipe.
[0012] Preferably, the connecting rod B is connected to the inner side of the connecting frame, and the connecting rod B has several sets of toothed holes near its lower end, with the upper end of the toothed holes being empty slots.
[0013] This invention has the following advantages: The initial positions of the first and second cleaning rollers are flush with the lower surface of the fixed plate. If the guardrail has a different shape and needs to be lowered, the initial opening of the valve inside the water inlet pipe is small, resulting in a smaller water flow. The initial water flow is only equal to that of the first and second cleaning rollers at their initial positions. When the positions change, if the first and second cleaning rollers move downwards, the initial water flow may be too small to reach the guardrail surface. Therefore, when motor A drives the threaded rod to lower the connecting frame, the connecting rod B is connected to the connecting frame, so it will drive the connecting rod B to lower synchronously. When the connecting rod B lowers, it will drive the gear to rotate through the toothed hole at the lower end. When the gear rotates, it will drive the internal valve to gradually open through the connecting shaft, thereby increasing the water flow and making the sprayed water flow equal to the descent distance, thus making the water source contact the guardrail more extensively and improving the cleaning effect.

[0023] Reference Figure 1-5 This utility model provides an embodiment of a guardrail cleaning device for highway maintenance, comprising a fixed plate 1, a connecting block 2 for improving overall stability fixedly connected to one side of the fixed plate 1, a height-adjustable connecting frame 3 provided at the upper end of the fixed plate 1, a driving motor A4 provided at the upper end of the connecting frame 3, a threaded rod 5 connected to the output end of the motor A4, a rotating motor B6 fixedly connected to both sides of the motor A4, a transmission shaft 7 connected to the lower end of the motor B6, a first cleaning roller 8 fixedly connected to the lower end of the rotating shaft 7, and a cleaning roller 8 provided on one side of the first cleaning roller 8. The second cleaning roller 9 is used for wiping. A connecting rod A10 is fixedly connected to the upper surface of the connecting block 2. Water inlet pipes 11 for transmission are provided on both sides of the connecting rod A10. A nozzle 12 is fixedly connected to the output end of the water inlet pipe 11. A gear 13 for control is provided on one side of the nozzle 12. A connecting shaft 14 is fixedly connected to the shaft center of one end of the gear 13. A valve 15 for controlling the water volume is fixedly connected to the end of the connecting shaft 14 away from the gear 13. A connecting rod B16 is provided on one side of the gear 13. A toothed hole 17 that meshes with the gear 13 is opened at the lower end of the connecting rod B16.
[0024] In an optional embodiment: two sets of fixing plates 1 are provided, and the two sets of fixing plates 1 are connected by connecting blocks 2. Three sets of connecting blocks 2 are provided, and both ends of each set are connected to the fixing plates 1. The connecting frame 3 is fixed to the upper end of the fixing plate 1 by connecting to the threaded rod 5. There are two sets of connecting frames 3. The two sets of fixing plates 1 are connected by connecting blocks 2, which improves the strength of the overall structure, thereby improving the overall stability of the equipment and extending the overall service life of the equipment to a certain extent.
[0025] In an optional embodiment: Motor A4 is connected to threaded rod 5. Two sets of motor A4 are provided, and both sets of motor A4 are fixedly connected to the upper center of the connecting frame 3. Threaded rod 5 passes through the center of fixed plate 1 and is threadedly connected to fixed plate 1. The connecting frame 3 is provided with two sets of motors B6 at both ends, totaling four sets. Motor A4 controls the lifting and lowering by rotating threaded rod 5. Since the connecting frame 3 is fixedly connected to the upper end of threaded rod 5, the lifting and lowering of threaded rod 5 synchronously drives the lifting and lowering of connecting frame 3. Since motor B6 is fixedly connected to both ends of connecting frame 3 and connected to the first cleaning roller 8 through rotating shaft 7, the lifting and lowering of connecting frame 3 drives motor B6 to lift and lower synchronously, thereby controlling the lifting and lowering of the first cleaning roller 8 and the second cleaning roller 9, thus adapting to guardrails of different heights and shapes, making them more convenient to use.
[0026] In an optional embodiment: the first cleaning roller 8 is rotated by the rotating shaft 7 driven by the motor B6. The first cleaning roller 8 is located at the front end of the equipment, and the second cleaning roller 9 is located at the rear end of the equipment. It is connected to the motor B6 through the rotating shaft 7 and is also driven to rotate by the motor B6. The first cleaning roller 8 at the front end cleans the guardrail. After cleaning, water stains will remain on the surface of the guardrail. If the wind blows dust onto the surface of the guardrail, it may adhere to the surface, resulting in a low cleaning effect. Therefore, after the first cleaning roller 8 finishes cleaning, the second cleaning roller 9 at the rear end will wipe the cleaned area dry, thereby removing the water stains remaining on the surface and preventing dust from adhering to the surface.
[0027] In an optional embodiment: the connecting rod A10 is connected to the middle set of three sets of connecting blocks 2, and its other end is connected to the transport vehicle. The water inlet pipe 11 is provided with two sets on both sides of the connecting rod A10. The end of the pipe close to the nozzle 12 extends through the connecting block 2 to the lower end. The nozzle 12 is set at an in-box angle. Both sets are close to the center, so that the spraying point is more in line with the surface of the guardrail and the cleaning effect is improved.
[0028] In an optional embodiment: Gear 13 is fixedly connected to one side of water inlet pipe 11 via connecting shaft 14. Water inlet pipe 11 extends through the outer wall of water inlet pipe 11 to the inside. Valve 15 rotates inside water inlet pipe 11 via gear 13. The outer diameter of valve 15 is slightly smaller than the inner diameter of water inlet pipe 11. The initial positions of the first cleaning roller 8 and the second cleaning roller 9 are flush with the lower surface of the fixed plate 1. If the guardrail shape is different and needs to be lowered, the water flow rate will decrease because the initial position of valve 15 inside water inlet pipe 11 is slightly open. The initial water flow rate is only equal to that of the first cleaning roller 8 and the second cleaning roller 9 at the initial position. When the position changes... When changes occur, if the first cleaning roller 8 and the second cleaning roller 9 move downwards, the initial water flow may be too small to spray onto the guardrail surface. Therefore, when the motor A4 drives the threaded rod 5 to lower the connecting frame 3, the connecting rod B16 will descend synchronously because it is connected to the connecting frame 3. When the connecting rod B16 descends, it will drive the gear 13 to rotate through the toothed hole 17 at the lower end. When the gear 13 rotates, it will drive the internal valve 15 to gradually open through the connecting shaft 14, thereby increasing the water flow and making the sprayed water flow equal to the descent distance. This allows the water source to contact the guardrail more extensively, thus improving the cleaning effect.
[0029] In an optional embodiment: the connecting rod B16 is connected to the inner side of the connecting frame 3. The connecting rod B16 has several sets of toothed holes 17 near its lower end. The upper end of the toothed holes 17 is an empty groove. Since the valve 15 is movable inside the water inlet pipe 11, if the toothed holes 17 drive the gear 13 to rotate continuously as the connecting rod B16 descends, it may cause the internal valve 15 to close, resulting in a smaller water flow. Therefore, the number of toothed holes 17 is matched with the size of the rotation of the gear 13. When passing through the last set of toothed holes 17, the valve 15 will be opened to the maximum extent. After the gear 13 passes through the last set of toothed holes 17, the connecting rod B16 will not drive the gear 13 to rotate further due to the empty groove, so the valve 15 remains open with a large water flow.
[0030] Working principle and process: The operator connects the connecting rod A10 to the mobile device, and then, according to the shape of the guardrail, the motor A4 drives the threaded rod 5 to rotate, controlling the connecting frame 3 to descend, thereby adjusting the position of the first cleaning roller 8 and the second cleaning roller 9. When the connecting frame 3 descends, it will simultaneously drive the connecting rod B16 to descend. As the connecting rod B16 descends, it will drive the gear 13 to rotate through the toothed hole 17, thereby gradually opening the valve 15 inside the water inlet pipe 11. During cleaning, the first cleaning roller 8 at the front end sprays water from the nozzle 12 to clean the guardrail. After cleaning, the second cleaning roller 9 at the rear end will wipe the cleaned area to remove surface water stains.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
