Description

Technical Field

[0001] The present invention relates to the field of municipal guardrail cleaning equipment, and particularly to a self-propelled guardrail cleaning machine. Background Art

[0002] In modern urban construction and transportation systems, road guardrails, as important facilities for ensuring traffic safety and regulating traffic order, their cleaning and maintenance directly affect the urban image and road use safety. Guardrails that are long-term exposed to the outdoor environment are vulnerable to dust, oil stains, water stains, and various pollutants. This not only reduces the aesthetic degree, but the accumulated dirt may also accelerate the aging of the guardrails, shorten the service life. If the stains block the reflective signs, it will pose a threat to night driving safety. Traditional guardrail cleaning methods mostly rely on manual operations. The cleaning personnel need to hold cleaning tools and complete the operation by wiping, brushing, etc. This method not only has a large labor intensity and low work efficiency, making it difficult to meet the cleaning needs of large-scale and long-distance guardrails, but also has safety hazards such as working at heights and vehicle traffic during the manual cleaning process. The cleaning quality is also difficult to guarantee due to differences in personnel operations. With the development of technology, some guardrail cleaning equipment has gradually emerged on the market, such as vehicle-mounted guardrail cleaning machines. Although such equipment has improved the cleaning efficiency to a certain extent, it has many limitations. On the one hand, it mostly uses spray cleaning methods, consuming a large amount of cleaning water, resulting in serious waste of water resources, and the cleaning water is easy to splash onto surrounding pedestrians, vehicles, and roads, causing secondary pollution and disputes. On the other hand, the equipment usually needs to be manually towed or mechanically towed to move, which is inconvenient to operate in complex road conditions or narrow sections, with poor flexibility. Moreover, the equipment structure is complex, and the coordination between components is not good. The cleaning effect is difficult to reach the ideal state, and it is unable to effectively remove stubborn stains on the guardrail surface, making it difficult to adapt to the diverse guardrail cleaning scenario requirements. Therefore, developing a high-efficiency, water-saving, safe, and self-propelled guardrail cleaning equipment has become an urgent problem in the industry. Summary of the Invention

Specific Embodiment

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment: Please refer to the attached Figure 1 - attached Figure 7 , the embodiment of the present invention provides a self-propelled guardrail cleaning machine, as Figure 1As shown in the figure, it includes a housing 1. The housing 1 serves as the basic framework of the entire device, providing installation support and protection for internal components. An opening slot 2 is provided in the middle of the housing 1. The opening slot 2 is used to accommodate the guardrail to be cleaned, and its size is designed according to common guardrail specifications to ensure that the guardrail can be smoothly placed and stably cleaned. Cleaning brushes 3 are movably installed on both sides of the inner wall of the opening slot 2 through guide rails. The guide rails can provide stable sliding guidance for the cleaning brushes 3. The cleaning brushes 3 are made of high-strength, wear-resistant and soft brush hair materials, which can effectively fit the surface of the guardrail and remove dust, dirt and stubborn stains during reciprocating motion. A reduction motor 4 is fixedly installed on one side of the top end of the housing 1. The reduction motor 4 serves as a power source and can provide stable and adjustable rotational speed to meet the requirements of different cleaning working conditions. The driving end of the reduction motor 4 is fixedly installed with a main shaft 5. The main shaft 5 transmits the power of the reduction motor 4 to each transmission component to drive the entire device to operate. First driven wheels 10 are movably installed on both the front and rear ends of the housing 1 near the reduction motor 4. The first driven wheels 10 are used to receive power transmission to realize the motion drive of the cleaning brushes 3. Flywheels 12 are fixedly installed on the outer ends of the first driven wheels 10. The flywheels 12 have a large moment of inertia, which can make the motion more stable and continuous, ensuring the stable reciprocating motion of the cleaning brushes 3. Straight slots 13 are provided in the middle of both the front and rear ends of the housing 1. The straight slots 13 provide a guiding and limiting space for the motion of the sliding blocks 14. Sliding blocks 14 are movably installed inside the straight slots 13, and the inner ends of the sliding blocks 14 are fixedly installed on the outer walls of the corresponding cleaning brushes 3. The sliding blocks 14 can drive the cleaning brushes 3 to perform linear reciprocating motion along the direction of the straight slots 13. Connecting rods 15 are movably installed on one side of the outer ends of the flywheels 12. The connecting rods 15 convert the circular motion of the flywheels 12 into the linear motion of the sliding blocks 14, and the movable connection methods at both ends ensure the flexible transmission of the motion. The ends of the connecting rods 15 are movably installed in the middle of the outer ends of the corresponding sliding blocks 14 to achieve precise power transmission. A number of cleaning slots 16 are provided on both sides of the inner walls of the front and rear sides of the opening slot 2 away from the cleaning brushes 3. The cleaning slots 16 are used to install cross brush plates 18 and related cleaning components to form a deep cleaning area. Short shafts 17 are movably installed inside the cleaning slots 16. The short shafts 17 provide a rotating support shaft for the cross brush plates 18. Cross brush plates 18 are fixedly installed on the inner ends of the short shafts 17. The cross brush plates 18 slap the cleaning water into fine water droplets by rotation to form a high-speed water-gas fluid, realizing the deep cleaning of the outer surface of the guardrail. A rotating column 27 is movably installed on the inner top of the opening slot 2 through a bearing seat. The bearing seat ensures that the rotating column 27 can rotate flexibly and stably. The rotating column 27 is a key component to realize the self-walking function of the device. A bidirectional spiral groove 28 is provided on the outer diameter of the rotating column 27. The bidirectional spiral groove 28 converts the rotational motion of the rotating column 27 into a linear reciprocating motion through a unique spiral structure. A movable block 29 is movably installed in the opening slot 2 near the lower position of the rotating column 27 through a guide rail. The guide rail provides stable linear motion guidance for the movable block 29.A round pin 30 is fixedly installed at the top of the movable block 29, and the top of the round pin 30 is movably arranged inside the bidirectional spiral groove 28. The sliding of the round pin 30 in the bidirectional spiral groove 28 can convert the rotational motion of the rotating column 27 into the linear motion of the movable block 29. The bottom end of the movable block 29 is movably installed with an L-shaped push rod 32 through a return spring 31. The return spring 31 provides a return elastic force for the L-shaped push rod 32. The L-shaped push rod 32 is used to push the whole device to move, realizing the self-walking function.

[0018] In this embodiment, a first transmission shaft 6 is movably installed on one side of the top of the housing 1 close to the reduction motor 4 through a bearing seat. The bearing seat ensures that the first transmission shaft 6 can rotate smoothly. The first transmission shaft 6 is used to transmit the power of the main shaft 5 to the first driven wheel 10. A first worm 7 is fixedly installed on the outer diameter of one side of the main shaft 5 below the first transmission shaft 6. The first worm 7 cooperates with the first worm gear 8 to realize speed reduction and change of the power transmission direction. A first worm gear 8 is fixedly installed on the outer diameter of the middle part of the first transmission shaft 6, and the inner side ends of the first worm gear 8 and the first worm 7 are meshed and connected. The meshing transmission between the two can transmit power stably and efficiently. First driving wheels 9 are fixedly installed at both the front and rear ends of the first transmission shaft 6. The first driving wheels 9 are used to drive the first driven wheels 10 to rotate. The outer diameters of the corresponding first driving wheels 9 and the first driven wheels 10 on the same side are connected by a first transmission belt 11. The first transmission belt 11 has a certain elasticity, which can buffer the impact during the transmission process and ensure the smoothness of the transmission.

[0019] Furthermore, guide wheels 42 are fixedly installed on the front and rear sides of one end of the upper part of the housing 1 close to the reduction motor 4 through spring rods 41. The spring rods 41 can make the guide wheels 42 closely adhere to the upper cross bar of the guardrail, providing guidance and support for the movement of the device, ensuring that the device moves smoothly along the guardrail. Universal wheels 43 are fixedly installed at the four corners of the bottom end of the housing 1. The universal wheels 43 enable the device to turn flexibly during the movement process, facilitating the movement of the device between guardrails at different positions.

[0020] Furthermore, second transmission shafts 20 are movably installed on the front and rear sides of one side of the top of the housing 1 far from the reduction motor 4 through bearing seats. The bearing seats ensure that the second transmission shafts 20 can rotate flexibly. The second transmission shafts 20 are used to transmit the power of the main shaft 5 to the cross brush plate 18. A first driving bevel gear 21 is fixedly installed on the outer diameter of one side of the main shaft 5 close to the second transmission shaft 20. The first driving bevel gear 21 cooperates with the first driven bevel gear 22 to realize the change of the power transmission direction. First driven bevel gears 22 are fixedly installed at the inner side ends of the second transmission shafts 20, and the inner side ends of the first driven bevel gears 22 are meshed with the outer diameter of the first driving bevel gear 21. The meshing transmission between the two can transmit power efficiently and stably.

[0021] Further, second driving cones 23 are fixedly installed on the outer ends of the second drive shafts 20. The second driving cones 23 are used to drive the rotation of the second driven cones 25 to achieve further power transmission. On both sides of the front and rear ends of the housing 1 close to the second drive shafts 20, movable shafts 24 are movably installed. The movable shafts 24 are used to support the second driven cones 25 and transmit power. Second driven cones 25 are fixedly installed on the tops of the movable shafts 24, and the second driven cones 25 are meshed and connected to the inner ends of the corresponding movable shafts 24. The meshing transmission between the two ensures that power can be accurately transmitted to the movable shafts 24. The outer ends of the short shafts 17 all extend to the outside of the housing 1 and are fixedly installed with second worm wheels 19. The second worm wheels 19 cooperate with the second worms 26 to achieve speed reduction and power transmission. A number of second worms 26 are evenly fixedly installed on the outer diameters of the movable shafts 24, and the second worms 26 are meshed and connected to the inner ends of the corresponding second worm wheels 19. Through multi-stage transmission, it is ensured that the cross brush plate 18 can obtain appropriate rotational speed and torque.

[0022] Further, a second driving wheel 33 is fixedly installed at the end of the main shaft 5. The second driving wheel 33 is used to drive the rotation of the second driven wheel 34 to transmit power to the rotating column 27. A second driven wheel 34 is fixedly installed at the end of the rotating column 27, and the second driven wheel 34 is connected to the outer diameter of the second driving wheel 33 through a second transmission belt 35. The second transmission belt 35 ensures the smoothness and reliability of power transmission. Further, a water tank 36 is fixedly installed in the middle of the top of the housing 1. The water tank 36 is used to store cleaning water, and its capacity is designed according to the cleaning operation duration and requirements. A water pump 37 is fixedly installed on the top of the water tank 36. As a water supply power source, the water pump 37 can pump out the water in the water tank 36 and transport it to the cleaning part. A water delivery pipe 38 is fixedly installed at the driving end of the water pump 37. The water delivery pipe 38 is used to transport cleaning water, and its material has good corrosion resistance and compressive resistance. The end of the water delivery pipe 38 is fixedly installed in the middle of a flow dividing pipe 39. The flow dividing pipe 39 is used to evenly distribute the cleaning water to each branch pipe 40. A number of branch pipes 40 are fixedly installed on both sides of the flow dividing pipe 39, and the ends of the branch pipes 40 all extend into the corresponding cleaning tanks 16. The branch pipes 40 can accurately transport the cleaning water near the cross brush plate 18 to ensure that the cleaning water can be effectively utilized.

[0023] Working principle: First, move the device to the side of the guardrail to be cleaned. Using the universal wheels 43 at the four corners of the bottom end of the housing 1, the position of the device can be flexibly adjusted. Place the guardrail in the opening groove 2 of the housing 1 so that the guardrail is within the working range of the cleaning brush 3 and the cross brush plate 18. Then start the reduction motor 4. The reduction motor 4 drives the main shaft 5 to rotate. The main shaft 5 drives the first worm 7 to rotate. The first worm 7 drives the first worm wheel 8 and the first transmission shaft 6 to rotate through meshing transmission with the first worm wheel 8. The first transmission shaft 6 drives the first driving wheels 9 on both sides to rotate. The first driving wheels 9 drive the two first driven wheels 10 and the flywheel 12 to rotate through the transmission of the first transmission belt 11. The rotating flywheel 12 drives one end of the connecting rod 15 to perform circular motion on its surface. The other end of the connecting rod 15 reciprocally pushes and pulls the sliding block 14 through the limiting action of the straight groove 13, thereby driving the cleaning brush 3 to reciprocate left and right. The bristles of the cleaning brush 3 are closely attached to the surface of the guardrail to clean the surface of the guardrail, effectively removing dust, dirt, and stubborn stains on the surface. At the same time, when the main shaft 5 rotates, it also drives the first driving bevel gear 21 to rotate. The first driving bevel gear 21 drives the first driven bevel gears 22 on both sides and the second transmission shaft 20 to rotate through meshing transmission with the first driven bevel gear 22. The second transmission shaft 20 drives the second driving bevel gear 23 at the outer end to rotate. The second driving bevel gear 23 drives the second driven bevel gear 25 and the movable shaft 24 to rotate through meshing transmission with the second driven bevel gear 25. The rotating movable shaft 24 drives all the second worms 26 to rotate. The second worms 26 drive all the second worm wheels 19 and the short shafts 17 to rotate through meshing transmission with the second worm wheels 19, thereby driving all the cross brush plates 18 in the cleaning tanks 16 to rotate. At this time, turn on the water pump 37. The water pump 37 pumps the cleaning water in the water tank 36, sends it into the shunt pipe 39 through the water delivery pipe 38, and then sends it into each cleaning tank 16 through the branch pipe 40. The rotating cross brush plate 18 pats the cleaning water into fine water droplets. These fine water droplets form a high-speed water-vapor fluid after mixing with air. The high-speed water-vapor fluid performs deep cleaning on the outer surface of the guardrail with a large impact force and coverage area. Compared with the traditional spray cleaning method of brushing first and then washing, this method not only improves the cleaning effect but also can more precisely control the use of cleaning water, reduce waste, and save more water resources. At the same time, due to the controllable movement trajectory of the high-speed water-vapor fluid, the cleaning water will not splash onto passers-by or passing vehicles, ensuring the cleanliness and safety of the surrounding environment, pedestrians, and vehicles. The spring rod 41 can make the guide wheel 42 adhere to the upper cross bar of the guardrail, providing guidance and stable support for the movement of the device and preventing the device from shifting during movement. When the main shaft 5 rotates, it also drives the second driving wheel 33 at the end to rotate. The second driving wheel 33 drives the second driven wheel 34 and the rotating column 27 to rotate through the transmission of the second transmission belt 35. When the rotating column 27 rotates, it drives the bidirectional spiral groove 28 on its outer surface to rotate, causing the round head pin 30 to slide inside it, while the movable block 29 is limited by the guide rail.It can only perform linear motion in the horizontal direction. Since the bidirectional spiral groove 28 is composed of two spiral grooves with opposite spiral directions but connected end to end, when the round head pin 30 moves to the tail of one of the spiral grooves, it will immediately enter the head of the other spiral groove and change the direction of motion. With the continuous rotation of the rotating column 27, it drives the round head pin 30 and the movable block 29 to perform reciprocating linear motion in the horizontal direction, and drives the L-shaped push rod 32 to move together. When the L-shaped push rod 32 moves to one end, its bottom will be blocked by the top cover of the guardrail, and the guardrail itself cannot move. As the L-shaped push rod 32 continues to move, it drives the whole device to move forward under the action of the reaction force. When the movable block 29 resets, the L-shaped push rod 32 will rotate when it touches the top cover of the guardrail until it completely crosses the top cover and then resets using the return spring 31. This cycle repeats to achieve the self-propelling function of the device, eliminating the process of manual or mechanical traction, reducing labor costs and equipment investment, making the cleaning operation more flexible and efficient, and adaptable to the cleaning requirements of guardrails with different lengths and shapes. At the same time, the layout of each component of the whole device is reasonable. The reduction motor 4 drives multiple cleaning and walking components through a series of transmission structures, with a compact structure. By simply starting the reduction motor 4, the water pump 37 and other operations, the automatic cleaning and walking of the guardrail can be achieved. The operation process is simple and easy to understand, reducing the working difficulty and labor intensity of the operator and improving work efficiency.
