Description

Technical Field

[0001] This invention relates to the field of road rolling device technology, specifically a road rolling device with an auxiliary compaction structure. Background Technology

[0002] A road roller is a heavy-duty mechanical device used for compaction operations in road and foundation engineering. It compacts materials such as soil and asphalt through its own weight or vibration, improving the stability and durability of the engineering structure. For example, a road roller with announcement number CN118087337B, used for slope compaction, relates to the field of road engineering technology. It includes a frame, a panel fixedly connected to the upper surface of the frame, and an operator's cab fixedly connected to the upper surface of the panel; a distance adjustment device, which adjusts the distance between the frame and the compaction device to prevent instability during slope compaction, thus enabling the road roller to compact the road surface on slopes. This distance adjustment device is used to adjust the roller's shaft length and includes a track bar slidably connected to the inner cavity of the distance adjustment device; and an angle adjustment device, which adjusts the angle between the compaction device and the frame, allowing the compaction device to tilt at an angle to the frame, achieving tight contact with and flattening of the sloping road surface.

[0003] For example, a dust-control road roller for construction engineering, with announcement number CN213625082U, includes a vehicle body and a rolling mechanism installed on one side of the vehicle body. The rolling mechanism includes a frame and a roller rotatably installed inside the frame. A mounting shell is fixedly installed at the top of the frame, and an exhaust fan is fixedly installed on the inner wall of the mounting shell. Two telescopic pipes are provided at the bottom of the frame, and a first collection box and a second collection box are respectively provided at the bottom of the two telescopic pipes. A cleaning component is provided on one side of the first collection box, and the cleaning component is located outside the roller. A mounting plate is fixedly installed at the bottom of both the first and second collection boxes by bolts, and a cleaning brush is fixedly installed at the bottom of the mounting plate. By collecting dust while preventing it from being stirred up, dust will not remain on the road surface, preventing it from affecting the compaction effect and aesthetics of the road surface. Furthermore, it eliminates the need for manual cleaning, effectively reducing the labor intensity of personnel. However, the above-mentioned road roller still has the following disadvantages in actual use:

[0004] 1. Traditional road rollers lack operational flexibility, have blind spots in compaction, fail to compact corner areas, are limited in operation on complex terrain, and have poor stability and fit. This results in insufficient contact between the steel wheel and the surrounding dam material, leading to localized loose compaction. They also cannot achieve precise control of the compaction trajectory and parameters, which can easily cause quality fluctuations.

[0005] 2. Furthermore, during the use of the road roller, some mud and sand adhere to the steel wheel, making it inconvenient to clean the surface of the steel wheel, which in turn affects the stability of the road rolling.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing road roller devices. Summary of the Invention

[0007] The purpose of this invention is to provide a road roller device with an auxiliary compaction structure to solve the problems of insufficient operational flexibility, blind spots, inadequate compaction of corner areas, limited operation in complex terrain, poor stability and fit, resulting in insufficient contact between the steel wheel and the surrounding dam material, and localized loose compaction.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a road roller device with an auxiliary compaction structure, comprising a body, a fixed frame fixed to the front end of the body, and a steel wheel rotatably mounted on the inner side of the fixed frame, and the steel wheel being driven by a motor;

[0009] It also includes: a movable shaft, which is rotatably disposed inside the steel wheel, and an eccentric wheel is fixedly installed on the outer side of the movable shaft, and the rotation of the eccentric wheel generates centrifugal force to drive the steel wheel to vibrate;

[0010] An air supply mechanism is installed at both ends of the steel wheel. The air supply mechanism generates gas through the vibration of the steel wheel to clean the surface of the steel wheel.

[0011] An auxiliary compaction mechanism is installed on both sides of the fixed frame. The auxiliary compaction mechanism is used to assist in compaction of narrow areas such as the corners of the dam body and the junction of the bank slope.

[0012] Preferably, the gas delivery mechanism includes a fixed shaft fixed to both ends of the steel wheel, and a connecting plate is fixed to the end of the fixed shaft away from the steel wheel. The edge of the connecting plate slides in contact with one end of the movable rod. At the same time, the movable rod passes through the inside of the fixed box. When the steel wheel vibrates, it can drive the fixed shaft and the connecting plate to move synchronously and push the movable rod to slide on the fixed box.

[0013] Preferably, the fixed box is located inside both ends of the steel wheel, and the other end of the movable rod is connected to a piston block. The edge of the piston block slides against the inner wall of the fixed cavity. The fixed cavity is located inside the fixed box. When the movable rod moves, it drives the piston block to slide inside the fixed cavity, compressing the gas inside the fixed cavity and expelling it.

[0014] Preferably, the movable rod and the fixed box are elastically slidably connected, and the piston block and the movable rod are distributed at equal angles on the fixed box. The fixed cavity is interconnected with the fixed pipe through the gas supply pipe, and the gas supply pipe is fixed between the fixed box and the fixed pipe. Gas can be transmitted to the fixed pipe through the gas supply pipe.

[0015] Preferably, the fixing tube is fixed to the inner side of both ends of the steel wheel, and the fixing tube is connected to the hose through a notch. The notch is opened at an equal angle on the inner side of the steel wheel. At the same time, the hose is fixed between the annular plate and the connecting tube. The gas in the fixing tube is transmitted to the gap between the annular plate and the steel wheel through the notch.

[0016] Preferably, the annular plate is rotatably sleeved on both ends of the steel wheel, and the outer surface of the annular plate is flush with the outer surface of the steel wheel. The connecting pipe is fixed to the inner side of the fixing frame, and air nozzles are installed on the connecting pipe at equal intervals. Gas is transmitted to the connecting pipe through the hose and finally discharged from the air nozzles to blow onto the steel wheel to clean it.

[0017] Preferably, the rotating shaft of the steel wheel is connected to the drive shaft via a pulley mechanism, and the diameter of the pulley on the drive shaft is smaller than the diameter of the pulley on the rotating shaft of the steel wheel. Furthermore, there is a gap between the end of the drive shaft away from the pulley and the end of the connecting shaft, and the cross-sections of the ends of the drive shaft and the connecting shaft that are close to each other are both rectangular structures. When the sleeve is fitted on the outside of the connecting shaft and separated from the drive shaft, the rotation of the steel wheel will not drive the rotation of the connecting shaft.

[0018] Preferably, the auxiliary compaction mechanism includes a sleeve block sleeved on the outside of the connecting shaft, and the sleeve block is slidably connected to both the connecting shaft and the drive shaft. A movable disc is fixed to the other end of the connecting shaft, and a fixing rod is fixed to the edge of the movable disc. When the sleeve block moves to be sleeved on the outside of the connecting shaft and the drive shaft, the rotation of the steel wheel can drive the movable disc to rotate synchronously.

[0019] Preferably, a sleeve plate is slidably sleeved on the outer side of the fixed rod, and a connecting frame is vertically fixed on the side of the sleeve plate. A tamping plate is connected to the bottom of the connecting frame, and the lowest point of the tamping plate is flush with the lowest point of the steel wheel. When the movable disc rotates, the sleeve plate is driven to slide on the fixed rod by the guidance of the fixed rod.

[0020] Preferably, the connecting frame slides through the support plate, and the upper end of the support plate is fixed to the fixed frame. The top of the support plate is rotatably connected by a connecting shaft. When the sleeve plate is raised or lowered, the connecting frame drives the tamping plate to rise and fall synchronously, thereby compacting the corner positions.

[0021] Compared with existing technologies, the beneficial effects of this invention are as follows: This road roller device with an auxiliary compaction structure optimizes the machine's steering system for narrow areas such as dam corners and bank slope junctions, reducing the minimum turning radius. Simultaneously, the auxiliary compaction mechanism allows the equipment to operate within 20cm of the edge, eliminating the need for additional small rammers for compaction, thus shortening the construction process by 15%. The steel wheel pressure sensor identifies oversized stones (over 80cm) in real time, automatically adjusting the amplitude and compaction speed to prevent loose compaction caused by the steel wheel being supported, while also reducing collision damage to the equipment from oversized stones. The workload of manually picking oversized materials is reduced by 60%. Specific details are as follows:

[0022] 1. The connecting plate pushes the movable rod, which can slide on the fixed box. When the movable rod moves the piston block in the fixed cavity, it can compress the gas inside and transmit it to the fixed pipe through the gas supply pipe. Then, it is transmitted to the gap between the annular plate and the steel wheel through the notch. The gas enters the connecting pipe through the hose and is finally discharged from the nozzle and blown onto the surface of the steel wheel. Therefore, the surface of the steel wheel can be cleaned by the generated gas when the steel wheel is rolling.

[0023] Furthermore, the annular plate remains stationary during the rotation of the steel wheel, thus neither affecting the rotation of the steel wheel nor hindering the transmission of gas.

[0024] 2. When the movable plate drives the fixed rod to rotate to different positions, it can drive the sleeve plate to slide on the fixed rod. Therefore, the connecting frame can be raised and lowered by the guidance of the sleeve plate. When it is raised and lowered, the tamping plate is raised and lowered synchronously, thereby assisting in the compaction of the corner positions and avoiding blind spots in construction. When the tamping plate is not needed, the sleeve block can be pulled to separate from the drive shaft. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-9 The present invention provides the following technical solution:

[0037] Example 1: To address the problems existing in the prior art, this example provides a road roller device with an auxiliary compaction structure, comprising a body 1, a fixed frame 2 fixed to the front end of the body 1, and a steel wheel 3 rotatably mounted on the inner side of the fixed frame 2, the steel wheel 3 being driven by a motor; further comprising: a movable shaft 4 rotatably disposed inside the steel wheel 3, an eccentric wheel 5 fixedly mounted on the outer side of the movable shaft 4, the eccentric wheel 5 generating centrifugal force to drive the steel wheel 3 to vibrate; an air supply mechanism disposed at both ends of the steel wheel 3, the air supply mechanism generating gas through the vibration of the steel wheel 3 to clean the surface of the steel wheel 3; and an auxiliary compaction mechanism disposed on both sides of the fixed frame 2, the auxiliary compaction mechanism being used to assist in compaction of narrow areas such as dam corners and bank slope junctions.

[0038] Existing road rollers sometimes accumulate mud and sand on the steel drum 3 during use, making it inconvenient to clean the surface of the drum 3 and thus affecting the stability of the road rolling process. Figures 1-6As shown, the gas delivery mechanism includes a fixed shaft 6 fixed to both ends of the steel wheel 3, and a connecting plate 7 fixed to the end of the fixed shaft 6 away from the steel wheel 3. The edge of the connecting plate 7 slides against one end of the movable rod 8, and the movable rod 8 passes through the inner side of the fixed box 9. The fixed box 9 is located inside both ends of the steel wheel 3, and a piston block 10 is connected to the other end of the movable rod 8. The edge of the piston block 10 slides against the inner wall of the fixed cavity 11, and the fixed cavity 11 is opened inside the fixed box 9. The movable rod 8 and the fixed box 9 are elastically slidably connected, and the piston block 10 and the movable rod 8 are distributed at equal angles on the fixed box 9. The fixed cavity 11 is interconnected with the fixed pipe 12 and the fixed pipe 13, and the gas delivery pipe 12 is fixed between the fixed box 9 and the fixed pipe 13. The fixed pipe 13 is fixed to the inner side of both ends of the steel wheel 3, and the fixed pipe 13 is connected to the flexible hose 16 through a notch 14. The notch 14 is opened at equal angles inside the steel wheel 3, and the flexible hose 16 is connected to the fixed pipe 13 through a notch 14. Pipe 16 is fixed between the annular plate 15 and the connecting pipe 17; the annular plate 15 is rotatably sleeved on both ends of the steel wheel 3, and the outer surface of the annular plate 15 is flush with the outer surface of the steel wheel 3; the connecting pipe 17 is fixed to the inner side of the fixed frame 2, and air nozzles 18 are installed on the connecting pipe 17 at equal intervals; during the operation of the road roller, the motor drives the steel wheel 3 to rotate and compact the stone, while the motor inside the steel wheel 3 drives the movable shaft 4 and the eccentric wheel 5 to rotate synchronously, so that the steel wheel 3 vibrates and compacts the stone. When the steel wheel 3 vibrates, it drives the fixed shaft 6 and the connecting plate 7 to move synchronously and change position. The connecting plate 7 pushes the movable rod 8, which can slide on the fixed box 9. When the movable rod 8 drives the piston block 10 to move in the fixed cavity 11, it can squeeze the gas inside and transmit it to the fixed pipe 13 through the air supply pipe 12. When the connecting plate 7 does not push the movable rod 8, the elasticity of the spring can drive the movable rod 8 and the piston block 10 to return to their original position. Figure 6 As shown, the gas generated by the extrusion can be transmitted through the notch 14 to the gap between the annular plate 15 and the steel wheel 3. The annular plate 15 is stationary during the rotation of the steel wheel 3, so it will not affect the rotation of the steel wheel 3 or hinder the transmission of gas. Then the gas enters the connecting pipe 17 through the hose 16 and is finally discharged from the nozzle 18 and blown onto the surface of the steel wheel 3. Therefore, the surface of the steel wheel 3 can be cleaned by the generated gas when the steel wheel 3 is rolling, preventing impurities from adhering and affecting the rolling process.

[0039] Example 2: Existing road rollers lack operational flexibility, have blind spots, fail to compact corner areas, are limited in operation on complex terrain, and have poor stability and fit. This results in insufficient contact between the steel wheel 3 and the surrounding dam material, leading to localized loose compaction. Precise control of the compaction trajectory and parameters is impossible, easily causing quality fluctuations. Therefore, this example uses the following technical solution: Figure 2 and Figures 7-9As shown, the rotating shaft of the steel wheel 3 is connected to the drive shaft 27 via a pulley mechanism. The diameter of the pulley on the drive shaft 27 is smaller than the diameter of the pulley on the rotating shaft of the steel wheel 3. A gap is left between the end of the drive shaft 27 away from the pulley and the end of the connecting shaft 25. The cross-sections of the ends of the drive shaft 27 and the connecting shaft 25 that are close to each other are both rectangular. The auxiliary compaction mechanism includes a sleeve block 26 sleeved on the outside of the connecting shaft 25. The sleeve block 26 is slidably connected to both the connecting shaft 25 and the drive shaft 27. A movable disc 19 is fixed to the other end of the connecting shaft 25, and a fixing rod 20 is fixed to the edge of the movable disc 19. A sleeve plate 21 is slidably sleeved on the outside of the fixing rod 20. A connecting frame 22 is vertically fixed to the side of the sleeve plate 21, and a tamping plate 23 is connected to the bottom of the connecting frame 22. The lowest point of the tamping plate 23 is flush with the lowest point of the steel wheel 3. The connecting frame 22 slides through the support plate 24, and the upper end of the support plate 24 is fixed to the fixed frame 2. The top of the support plate 24 is rotatably connected to the connecting shaft 25. When it is inconvenient to press the corner, the sleeve block 26 is pulled to slide on the connecting shaft 25, so that the sleeve block 26 slides and connects with the drive shaft 27. In this way, during the rotation of the steel wheel 3, its shaft can drive the drive shaft 27 to rotate synchronously through the belt pulley mechanism. Then, the sleeve block 26 drives the movable disc 19 to rotate. When the movable disc 19 drives the fixed rod 20 to rotate to different positions, it can drive the sleeve plate 21 to slide on the fixed rod 20. Therefore, the connecting frame 22 can be driven to rise and fall through the guidance of the sleeve plate 21. When rising and falling, the tamping plate 23 is driven to rise and fall synchronously, thereby assisting in compacting the corner and avoiding blind spots in construction. When the tamping plate 23 is not needed, the sleeve block 26 can be pulled to separate from the drive shaft 27.

[0040] Although the present invention 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 invention should be included within the protection scope of the present invention.
