Description

Technical Field

[0001] The invention relates to the technical field of road maintenance equipment, and in particular to a novel road guardrail cleaning device. Background Art

[0002] The road guardrail cleaning device is a device specially used to clean the surface of road guardrails. With the busy traffic, especially in some cities' highways, urban roads, bridges and other areas, road guardrails will accumulate a lot of dirt, dust, oil stains, and some other pollutants. In order to ensure the neat appearance of the guardrails, extend their service life and ensure the safety of the road, it is particularly important to clean the guardrails regularly. In some large cities or busy traffic sections, special road sweepers are used to automatically clean guardrails and other road facilities.

[0003] When a road sweeper cleans the guardrail, it usually only uses a brush to spray water on the guardrail. However, a large amount of water droplets will remain on the surface of the guardrail after cleaning. If the metal guardrail (such as iron, aluminum alloy, etc.) is not wiped dry after cleaning, the water will remain on the surface for a long time, which may cause surface oxidation or rust, especially at the joints or welding points of the metal guardrail. Moisture may accelerate the occurrence of corrosion and shorten the service life of the guardrail. The residual moisture on the surface of the guardrail will adhere to dust again. At the same time, in areas with lower temperatures, ice will also appear. Guardrails that are not wiped dry after cleaning may make the ground or surrounding areas slippery, increasing the risk of slipping. Therefore, a new type of road guardrail cleaning device is usually needed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure more clear, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure.

[0039] See also Figure 1-Figure 3 , Figure 6 as well as Figure 7The embodiment of the present invention provides a novel road guardrail cleaning device, including a telescopic arm 5, which is a prior art, and is installed on an operating vehicle for guardrail cleaning, and can adjust the placement of the device according to the position of the guardrail.

The belt transmission mechanism 11 includes pulleys fixedly arranged on the ball screw 16, the ball screw 17, the sliding shaft 19 and the mounting shaft 31, and a conveyor belt is rotatably installed between every two pulleys.

[0040] It also includes a cleaning component 2, which is installed on the mounting bracket 1 and is used to flush both sides of the guardrail. This is the prior art. The cleaning component 2 removes dirt, dust, oil stains, bird droppings, etc. on the surface of the guardrail through the physical friction of the bristles. A brush is provided in the cleaning component 2. The brush is usually made of wear-resistant materials (such as nylon, steel wire or other synthetic fibers) and can efficiently clean various common dirt. It also includes a shielding plate 3, which is fixedly installed on the mounting bracket 1 to prevent impurities cleaned by the cleaning component 2 from splashing to the other side, ensuring the effect of subsequent drying of the guardrail. At the same time, the shielding plate 3 is set in an inverted U shape to ensure that the guardrail can pass through it smoothly.

[0041] The utility model also comprises two connecting rods 14, both ends of which are respectively fixedly mounted with arc-shaped slides 9, and the two upper arc-shaped slides 9 are fixedly arranged on the mounting bracket 1, and a rotating lifting structure is commonly installed between every two arc-shaped slides 9, and the two sets of rotating lifting structures are symmetrically arranged, and cleaning rings 6 are installed on the two sets of rotating lifting structures, and the rotating lifting structure drives the cleaning rings 6 to rotate and lift to wipe the residual water after brushing on both sides of the guardrail, and the rotating lifting structure comprises rotating rings 32 which are respectively threadedly mounted on the ball screw 16 and the ball screw 2 17, wherein the outer rotating sleeve of one rotating ring 32 is provided with a sliding rod 1 20, and the outer rotating sleeve of the other rotating ring 32 is provided with a sliding rod 21, and the upper ends of the mounting shaft 31 and the sliding shaft 19 are fixedly mounted with a limiting rod 18, and the two sliding rods 10 are both slidably mounted outside the corresponding limiting rod 18, and the cleaning ring 6 is rotatably mounted between the sliding rod 1 20 and the sliding rod 2 21.

[0042] Turn on the motor 4 to drive the rotating shaft 7 to rotate, the rotation of the rotating shaft 7 drives the two gears 1 8 to rotate, the two gears 1 8 rotate through the two gears 2 12 to drive the two gears 3 15 to rotate, the two gears 3 15 rotate and respectively drive the ball screw 1 16 and the installation shaft 31 to rotate, the installation shaft 31 rotates and drives the sliding rod 20 to rotate, the ball screw 16 rotates and drives the sliding rod 20 to slide, so that the sliding rod 20 rotates up and down, the ball screw 16 rotates and drives the sliding shaft 19 and the ball screw 2 17 to rotate at the same time through the two conveyor belts, the sliding rod 21 rotates at the same time with the sliding rod 1 20, the sliding rod 1 20 and the sliding rod 2 21 drive the cleaning ring 6 to rotate and lift to wipe the residual water droplets on the guardrail, and the rotary lifting mechanism can reduce the residual water droplets on the guardrail through multiple wiping or rolling actions. Through this dynamic erasing, water droplets will not stay on the surface, thus preventing watermarks or mineral deposits from evaporating, which is very important for maintaining the beauty of the guardrail and preventing surface corrosion. Water droplets remaining on the guardrail, especially under light conditions, will form reflections, affect the line of sight, and reduce visibility, especially when driving at night or in rainy days. Through the clearing action of the rotary lifting, the surface of the guardrail can be kept clean and clear, thereby improving the clarity of sight and enhancing safety. If the guardrail is in cold climate conditions, water droplets are easy to accumulate and freeze, forming a frost layer, affecting sight or safety. The rotary lifting system can help water droplets be wiped or shaken off in time, reducing the chance of water droplets accumulating on the guardrail, thereby effectively avoiding the occurrence of frost or frost.

[0043] See also Figure 4-Figure 5A telescopic structure for wiping moisture on the upper and lower sides of the guardrail is installed on the rotating lifting structure. The telescopic structure includes a plurality of sliding holes opened at the upper and lower ends of the sliding rod 21. A spring 2 is fixedly installed in each sliding hole. A trigger block 23 is fixedly installed at one end of each spring 2, and the trigger block 23 is slidably set in the sliding hole. A mounting plate 26 is fixedly installed on each trigger block 23, and a cleaning block 22 is fixedly installed on each mounting plate 26.

[0044] A plurality of card slots are provided on the inner side of the cleaning ring 6, and each trigger block 23 is used in conjunction with a corresponding card slot. When the cleaning ring 6 rotates to be in contact with the guardrail, the trigger block 23 close to the side of the guardrail will be squeezed. The trigger block 23 is squeezed through the mounting plate 26 to drive the corresponding cleaning block 22 to shrink toward the center of the sliding rod 21 to prevent the guardrail from affecting the movement of the cleaning block 22. The trigger block 23 and the corresponding cleaning block 22 are staggered in the vertical direction, so that the trigger block 23 can first contact the guardrail to drive the cleaning block 22 to move, and prevent the guardrail from getting stuck with the cleaning block 22 before contacting the trigger block 23. When the cleaning ring 6 moves to exceed the highest point and the lowest point of the guardrail, the cleaning block 22 is extended at this time, and the length of the extended cleaning block 22 exceeds the thickness of the cleaning ring 6, so that the cleaning block 22 can fully wipe the upper and lower sides of the guardrail during the descent and rise process, ensuring that the moisture on the surface of the guardrail is fully wiped off.

[0045] See also Figure 5 , Figure 8-Figure 11 , the two arc-shaped slides 9 above are provided with arc-shaped holes, and the two arc-shaped holes are slidably installed with connecting rods 27, and the two connecting rods 27 are fixedly connected to the corresponding ring sleeves, and one end of the two connecting rods 27 is fixedly installed with vertical rods 28, and two extrusion plates 33 are fixedly arranged on the two vertical rods 28, and the multiple extrusion plates 33 are fixedly connected with guide pipes, and the lower ends of the multiple guide pipes are connected with the collection box 29. The two extrusion plates 33 are arranged up and down, respectively at the highest point and the lowest point, to ensure the rotation of the cleaning block 22. When the cleaning block 22 rotates to be attached to the extrusion plates 33, the water on the cleaning block 22 is squeezed onto it. The extrusion plates 33 are arranged in an arc shape, so that the squeezed water can smoothly enter the guide pipe through its surface to prevent water from overflowing, and at the same time, the water flow rate can be accelerated (the arc-shaped arrangement of the extrusion plates 33 is similar to a funnel shape), and the collected water enters the collection box 29 through the guide pipe for collection.

[0046] It also includes two connecting frames 24, which are respectively installed on the corresponding rotating lifting structures. The two connecting frames 24 are both equipped with a drying structure for squeezing the cleaning ring 6. The drying structure includes two squeezing rods 30 rotatably installed on the connecting frames 24. The two squeezing rods 30 are both provided with guide grooves. The guide grooves are spirally arranged. The spiral guide grooves can make the water flow orderly along the spiral path, which can not only effectively guide the water flow, but also control the speed and direction of the water flow to a certain extent. By accurately controlling the flow of water and avoiding the water flow being too fast or too slow, it can be ensured that the water is discharged efficiently and evenly; two guide plates 25 are fixedly installed on the connecting frame 24, and the collecting box 29 is fixedly arranged at the lower end of the two guide plates 25. The setting of the guide plate 25 can prevent the water from being thrown out by the two squeezing rods 30, and at the same time collect the thrown out water in the collecting box 29 under its guidance.

[0047] A collecting box 29 is installed on both sets of drying structures, and a trigger structure for cleaning the cleaning ring 6 is installed in both collecting boxes 29. The trigger structure includes two limit frames 38 rotatably installed in the collecting box 29, and second gears 41 are slidably installed in the two limit frames 38. A circular plate 42 is slidably provided on the upper ends of the two limit frames 38. A pull rope 39 is fixedly provided between the two second gears 41 and the corresponding circular plates 42. A guide rod is fixedly installed on the two circular plates 42, and a sealing plug 36 is fixedly installed on the lower ends of the two guide rods. A water outlet pipe 37 is fixedly connected to the collecting box 29, and the sealing plug 36 is sealed and engaged in the water outlet pipe 37. A vertical round rod is fixedly provided in the water outlet pipe 37, and a guide groove is opened on the sealing plug 36, and the vertical round rod slides in the guide groove. The two drainage plates 25 A cleaning assembly is installed together therebetween, and the cleaning assembly includes semi-arc teeth fixedly arranged at the lower ends of the two extrusion rods 30, spring shafts are rotatably installed on the two guide plates 25, first gears 40 are fixedly installed at the lower ends of the two spring shafts, and a wedge block is fixedly installed on the first gear 40. When the water level in the collecting box 29 reaches the same horizontal plane as the semi-arc teeth and the first gear 40, the second gear 41 is meshed with the semi-arc teeth and the first gear 40, damping bearings are rotatably installed on the two spring shafts, and scrapers 1 34 are fixedly installed on the two damping bearings, and scrapers 2 35 are fixedly installed on one of the guide plates 25. Scrapers 2 35 are used to scrape impurities on the outside of the cleaning ring 6, and the impurities scraped by scrapers 2 35 can slide along its surface into the collecting box 29.

[0048] When the water collected in the collecting box 29 rises, the second gear 41 slides upward on the limiting frame 38 under the buoyancy of the water. When the water level reaches the same horizontal plane as the semi-arc teeth and the first gear 40, the second gear 41 is meshed with the semi-arc teeth and the first gear 40. When the squeezing rod 30 rotates, the semi-arc teeth drive the second gear 41 and the limiting frame 38 to rotate. The rotation of the second gear 41 drives the first gear 40 to rotate. In the initial state, the scraper 1 34 is separated from the squeezing rod 30, and the scraper 2 35 is in contact with the outer side of the cleaning ring 6. When the first gear 40 rotates, the scraper 1 34 is driven to rotate through the spring shaft. The scraper 34 moves until the scraper 34 rotates to fit with the extrusion rod 30. Under the action of the damping bearing, the scraper 34 is always in contact with the extrusion rod 30, so that impurities on the outer side of the extrusion rod 30 that has been used for a period of time can be scraped off. When the semi-arc teeth are separated from the second gear 41, the scraper 34 rebounds under the action of the spring shaft. At this time, the scraper 34 vibrates, and impurities thereon can fall into the collection box 29. A filter screen is provided on the bottom side of the water outlet pipe 37 to prevent impurities from being discharged. At the same time, the water outlet pipe 37 is connected to the water pipe connected to the cleaning component 2, so that the water used for wiping can be reused to reduce resource waste. When the first gear 40 rotates, it will drive the circular plate 42 to slide upward in the limit frame 38 through the wedge block. At this time, the circular plate 42 drives the sealing plug 36 to rise upward through the guide rod, so that the water outlet pipe 37 is opened. At this time, the water in the collection box 29 is discharged for reuse. When the water level drops, the second gear 41 will drop again. At this time, the squeeze plate 33 is driven by the pull rope 39 to slide downward in the limit frame 38 again to return to the initial position. After the squeeze plate 33 moves to the initial position, the sealing plug 36 is driven by the guide rod to seal the water outlet pipe 37 again, so as to ensure the subsequent use of the collection box 29 and realize automatic operation. At the same time, the setting of the vertical round rod can prevent the sealing plug 36 from detaching or tilting, so as to ensure the sealing of the water outlet pipe 37.
