Description

Technical Field

[0001] The invention relates to the technical field of road construction, and more particularly to a uniform compacting device of a road roller. Background Art

[0002] During road construction and maintenance, uniform compaction of the road surface is a key step to ensure road quality and service life. However, traditional rollers usually compact the road surface with a single compaction roller, but due to the non-uniformity of road materials and the limitations of construction conditions, some areas are often not compacted enough, resulting in loose asphalt on the road surface, which may cause collapse and damage in the later stage.

[0003] Traditional rollers usually use rollers to repeatedly roll the road surface to compact the road surface. During the paving process, the asphalt laid in some areas is relatively weak, or the gravel laid on some roadbeds is relatively loose. As a result, when the roller rolls the road surface with rollers, some areas are not compacted and may still be loose, thus affecting the overall compaction effect and the uniformity of the road surface. After the road surface is paved, it is rolled by large vehicles in the later stage, causing depressions in the fluffy asphalt areas or the uncompacted roadbed areas. Summary of the invention

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. In the present invention, an asphalt release agent such as silicone oil is injected into a storage box. When the smear cotton absorbs the silicone oil and reaches a saturated state, the release agent is applied to the first roller at one end surface of the smear cotton located outside the storage box. When the roller pushes the mounting plate forward, the first roller and the second roller roll on the road surface, thereby compacting the road surface. Since the release agent is applied to the first roller, the asphalt laid on the road surface is prevented from adhering to the first roller. When the first roller passes through the asphalt road surface, the release agent will remain on the asphalt road surface, and the asphalt is also prevented from adhering to the compaction roller and the second roller.

[0033] 2. In the present invention, through the elastic force of the first spring and the second spring, the first spring and the second spring push the arc pressure plate downward and press the compaction roller downward, so that multiple compaction rollers compact the road surface compacted by the first roller again, thereby compacting the fluffy parts of the asphalt on the road surface after the first roller is compacted by the compaction roller.

[0034] 3. In the present invention, the concave part that appears after compaction by the compaction roller of the flatness detector is detected, and the detection information is transmitted to the servo motor and the positioner on the sliding block. The servo motor drives the screw to rotate and drives the sliding block to move horizontally, driving the discharge pipe and the positioner to move horizontally. The positioner locates the concave part and transmits the information to the servo motor and the automatic control valve in the discharge pipe. The servo motor stops rotating, and the automatic control valve in the discharge pipe opens, so that the asphalt in the asphalt storage box slides down through the discharge pipe to the concave part of the road surface, thereby facilitating the filling of the concave part of the road surface. The rotating roller rolls the filled part flat, and when the second roller passes the filled part again, it rolls the filled part again, thereby compacting the road surface flat, avoiding the asphalt laid in the road surface area being relatively fluffy and causing later collapse, and to a certain extent improving the uniformity of road surface compaction, thereby reducing the occurrence of concave parts in the road surface during use in the later stage.

[0035] 4. In the present invention, by injecting asphalt and gravel into the outer cylinder, not only the gravity of the first roller can be increased, so that the first roller can roll the road surface flat when rolling on the road surface, but also because the asphalt and gravel roll in the outer cylinder during the rolling process of the first roller, so that the asphalt and gravel are fused with each other, and the asphalt and gravel are mixed. At the same time, because the temperature is high after the asphalt is laid, when the roller rolls the road surface through the first roller, the first roller will also carry a lot of heat, so that the first roller transfers the heat to the asphalt in the outer cylinder, thereby achieving the effect of keeping the asphalt warm.

[0050] Embodiment 1 further describes a uniform compaction device for a road roller provided by the present invention.

[0051] A uniform compacting device for a road roller comprises a mounting plate 1, to which a vertically arranged fixed plate 2 is fixedly connected, and on both side walls of the fixed plate 2 are arranged a first connecting frame 3 and a second connecting frame 4, a first rolling roller 5 is rotatably connected in the first connecting frame 3, and a second rolling roller 6 is rotatably connected in the second connecting frame 4, the first connecting frame 3 is fixedly connected to the side wall of the fixed plate 2, and the second connecting frame 4 is rotatably connected to the side wall of the fixed plate 2, and further comprises a compacting roller 7, the compacting roller 7 is arranged on the first connecting frame 3, and a rotating shaft is fixedly connected to the outer side wall of the second connecting frame 4, and the end of the rotating shaft is rotatably connected to the fixed plate 2, when the second connecting frame 4 rotates, the second rolling roller 6 is driven to rotate, so that the second rolling roller 6 rolls the road surface in an inclined manner, so that the road surface is inclined towards the side ditch, and when the road surface is paved, it is convenient for rainwater to flow into the side ditch through the inclined surface of the road surface on rainy days.

[0052] The flatness detector 8 is arranged at the bottom of the first connecting frame 3, and the flatness detector 8 is located on one side of the compaction roller 7. The flatness detector 8 is used to detect the flatness of the road surface. The flatness detector 8 is used to detect the flatness of the road surface and determine whether there are any concave parts in the road surface. The flatness detector 8 can use an existing 3D laser scanner.

[0053] Asphalt storage box 9, the asphalt storage box 9 is fixedly connected to the lower surface of the mounting plate 1, and a driving mechanism is arranged on the inner wall of the first connecting frame 3. A discharge pipe 10 is fixedly connected to the bottom of the asphalt storage box 9, and the discharge pipe 10 cooperates with the driving mechanism, and the driving mechanism is connected with the flatness detector 8 through a signal. An automatic control valve is arranged in the discharge pipe 10, and the automatic control valve cooperates with the driving mechanism. When the flatness detector 8 detects a concave part of the road surface, the flatness detector 8 transmits the information to the driving mechanism, and the driving mechanism drives the discharge pipe 10 to move. When the discharge pipe 10 moves to the concave part, the driving mechanism transmits the information to the automatic control valve. At this time, the automatic control valve opens, and the asphalt in the asphalt storage box 9 slides down to the concave part through the discharge pipe 10, and fills the concave part, thereby reducing the concave condition of the road surface.

[0054] A connecting plate 11 is provided on the lower surface of the second connecting frame 4, one end of the connecting plate 11 is fixedly connected to the side wall of the fixed plate 2, and both ends of the connecting plate 11 are fixedly connected to the electric telescopic rod 12, the upper end of the electric telescopic rod 12 is movably connected to the second connecting frame 4, and the upper end surface of the electric telescopic rod 12 is rotatably connected to a slider, and the slider is slidably connected to the second connecting frame 4. When one of the electric telescopic rods 12 pushes one end of the second connecting frame 4 upward through the slider, the second connecting frame 4 drives the rotating shaft and the second rolling roller 6 to rotate, so that the second rolling roller 6 is in an inclined state, which is convenient for the second rolling roller 6 to roll the road surface in an inclined state and roll the road surface in an inclined state.

[0055] A rotating roller 13 is rotatably connected to the connecting plate 11, and the lower end surface of the rotating roller 13 is flush with the lower end surface of the first roller 5. When the electric telescopic rod 12 pushes one end of the second connecting frame 4 upward, the rotating roller 13 can not only support the connecting plate 11, but also compact the filled asphalt downward when the discharge pipe 10 fills the concave part of the road surface.

[0056] The lower surface of the mounting plate 1 is fixedly connected to a storage box 14, which is used to load an isolation agent. A smear cotton 15 is fixedly connected inside the storage box 14. One end of the smear cotton 15 passes through the side wall of the storage box 14 and contacts the upper end surface of the first roller 5. The isolation agent is an asphalt isolation agent such as silicone oil. The smear cotton 15 smears the silicone oil on the first roller 5 to prevent the laid asphalt from adhering to the first roller 5.

[0057] A first limiting rod 16 is fixedly connected to the inner side wall of the first connecting frame 3 , and a compacting roller 7 is sleeved on the first limiting rod 16 . There are at least two compacting rollers 7 .

[0058] An arc-shaped pressure plate 17 is provided on the upper surface of the compacting roller 7, the inner arc wall of the arc-shaped pressure plate 17 contacts the outer ring wall of the compacting roller 7, the upper surface of the arc-shaped pressure plate 17 is fixedly connected to a first spring 40, and the upper end cover of the first spring 40 is fixedly connected to the lower surface of the mounting plate 1.

[0059] The upper surface of the arc-shaped pressure plate 17 is fixedly connected with a second limiting rod 18, the upper end of the second limiting rod 18 passes through the lower surface of the mounting plate 1 and is fixedly connected to a limiting block 19, the lower surface of the limiting block 19 is fixedly connected with a second spring 20, the lower end of the second spring 20 is fixedly connected to the upper surface of the mounting plate 1, a through hole is opened on the compacting roller 7, the diameter of the through hole is greater than the diameter of the first limiting rod 16, and the natural state of the first spring 40 is a fully extended state, the natural state of the second spring 20 is a fully contracted state, and the first spring 40 and the second spring 20 pushes the compacting roller 7 downward through the arc pressure plate 17, and when the first spring 40 and the second spring 20 are in the natural state, the lower end surface of the compacting roller 7 is located at the lower side of the first roller 5, so that the arc pressure plate 17 pushes the compacting roller 7 downward, so that the compacting roller 7 rolls the road surface again, thereby further compacting the road surface, and it is convenient to compact the soft area of ​​the road surface. Since the soft area of ​​the road surface is concave after compaction, it is convenient for the discharge pipe 10 to discharge asphalt into the concave part after compaction to fill the concave part of the road surface.

[0060] The driving mechanism includes a lead screw 21 , which is rotatably connected to the inner wall of the first connecting frame 3 .

[0061] The servo motor 22 is fixedly connected to the outer side wall of the first connecting frame 3 , and the output shaft of the servo motor 22 passes through the side wall of the first connecting frame 3 and is fixedly connected to the end of the lead screw 21 .

[0062] The sliding block 23 is threadedly connected to the lead screw 21. A strip-shaped slide groove 24 is provided on the inner side wall of the first connecting frame 3. One end of the sliding block 23 is slidably connected in the strip-shaped slide groove 24. The lower end of the discharge pipe 10 is fixedly connected to the sliding block 23. A nut is fixedly connected to the sliding block 23. The nut is threadedly connected to the lead screw 21. When the lead screw 21 rotates, the sliding block 23 is driven to move horizontally by the restriction of the thread. A positioner is provided on the sliding block 23. The positioner is used to drive the moving position of the sliding block 23. The positioner, the servo motor 22, and the flatness detector 8 are all connected through signals. When the flatness detector 8 detects that the road surface is concave, the flatness detector 8 detects that the road surface is concave. When the flatness detector 8 detects a concave part, the positioner transmits information to the servo motor 22 and the positioner. After receiving the information, the servo motor 22 drives the lead screw 21 to rotate, thereby driving the sliding block 23 to move, and driving the discharge pipe 10 and the positioner to move. When the sliding block 23 moves to just above the concave part detected by the flatness detector 8, the positioner transmits information to the servo motor 22. At this time, the servo motor 22 stops rotating, and the automatic control valve on the discharge pipe 10 opens. The asphalt slides downward through the discharge pipe 10 to the concave part, thereby filling the concave part. The discharge pipe 10 is a telescopic hose, which is convenient for the lower end of the discharge pipe 10 to move with the movement of the sliding block 23.

[0063] Working principle: The mounting plate 1 is mounted on the front end of the roller by means of existing technology such as screws, so that the second roller 6 is close to the roller, and then asphalt is injected into the asphalt storage box 9, and then the flatness detector 8, the servo motor 22, the positioner on the sliding block 23, and the automatic control valve in the discharge pipe 10 are electrically connected to the storage device in the prior art such as a battery, and at the same time, an asphalt isolation agent such as silicone oil is injected into the storage box 14. When the smear cotton 15 absorbs the silicone oil and reaches a saturated state, the end surface of the smear cotton 15 located outside the storage box 14 smears the isolation agent on the first roller 5. When the roller pushes the mounting plate 1 forward, the first roller 5 and the second roller 6 roll on the road surface, so that the road surface is compacted. Since the first roller 5 is coated with the isolation agent, the asphalt laid on the road surface is prevented from adhering to the first roller 5. When the first roller 5 passes through the asphalt road surface, the isolation agent will remain on the asphalt road surface, and the asphalt is also prevented from adhering to the compaction roller 7 and the second roller 6.

[0064] If the asphalt is directly below the first roller 5 and the asphalt is relatively loose, while the asphalt on both sides is relatively thick, since the first roller 5 is cylindrical, during the rolling and compacting process of the first roller 5, the contact pressure between the roller 5 and the road surface will be different in the middle and on both sides. In the case where the middle is loose and the two sides are thick, the two sides of the first roller 5 will first contact the thicker asphalt layer and bear greater pressure, while the pressure on the loose part in the middle is relatively small, which will make it difficult for the loose part in the middle to be fully compacted, resulting in uneven compaction of the road surface. At this time, through the elastic force of the first spring 40 and the second spring 20, the first spring 40 and the second spring 20 push the arc pressure plate 17 downward and press the compacting roller 7 downward, so that multiple compacting rollers 7 roll the road surface rolled by the first roller 5 again, so that the compacting roller 7 compacts the fluffy parts of the asphalt on the road surface after the first roller 5 is rolled, and the compacting roller 7 compacts the fluffy areas of the road surface, and the road surface will sag downward after the compacting roller 7 compacts the fluffy areas. At this time, the flatness detector 8 is turned on to detect the flatness of the road surface.

[0065] When the flatness detector 8 detects that the road surface is sunken, the flatness detector 8 transmits the information to the servo motor 22 and the positioner on the sliding block 23. The servo motor 22 drives the lead screw 21 to rotate. Since the sliding block 23 is threadedly connected to the lead screw 21 and the sliding block 23 slides in the strip slide 24, the sliding block 23 is restricted by the strip slide 24 to rotate with the rotation of the lead screw 21. Therefore, during the rotation of the lead screw 21, the sliding block 23 is driven horizontally by the thread, and the discharge pipe 10 and the positioner are driven horizontally. When the positioner detects that the sliding block 23 moves to the top of the sunken part, the positioner transmits the information to the servo motor 22 and the discharge pipe The automatic control valve in 10 and the servo motor 22 stop rotating, while the automatic control valve in the discharge pipe 10 is opened, so that the asphalt in the asphalt storage box 9 slides down through the discharge pipe 10 to the sunken part of the road surface, thereby filling the sunken part of the road surface. In the process of the roller pushing the first roller 5 and the second roller 6 to roll forward, when the rotating roller 13 passes through the filling part of the road surface, the rotating roller 13 rolls the filling part flat, and when the second roller 6 passes through the filling part again, it rolls the filling part again, thereby compacting and flattening the road surface, avoiding the asphalt laid in the road surface area being relatively fluffy and causing subsequent collapse, and to a certain extent improving the uniformity of road surface compaction.

[0066] When the roller compacts the road surface near the ditch, the electric telescopic rod 12 on the side away from the ditch is started, and the electric telescopic rod 12 pushes one end of the second connecting frame 4 upward, and the edge of the second connecting frame 4 rotates upward, so that the end of the second roller 6 near the ditch tilts downward. When the second roller 6 rolls the road surface, the road surface near the ditch bears a greater load, resulting in the cleaning of the ditch. This makes it easier for water on the road surface to be discharged into the ditch in rainy weather, avoiding water accumulation on the road surface and bringing convenience to pedestrians.

[0077] The upper end of the conveying cylinder 34 is connected to a discharge pipe 38 , one end of the discharge pipe 38 is fixedly connected to the asphalt storage box 9 , and the conveying cylinder 34 is connected to the asphalt storage box 9 through the discharge pipe 38 .

[0078] A driving motor 39 is fixedly connected to the top of the conveying cylinder 34. The output shaft of the driving motor 39 passes through the top of the conveying cylinder 34 and is fixedly connected to the upper end surface of the rotating shaft 36. The driving motor 39 is connected to the automatic control valve in the discharge pipe 10 through a signal. When the automatic control valve opens, the information is transmitted to the driving motor 39. After receiving the information, the driving motor 39 drives the auger 37 to rotate through the rotating shaft 36, thereby transporting the asphalt in the feed box 35 to the asphalt storage box 9.

[0079] Working principle: the vertical section of the connecting pipe 32 is rotated upward so that the port of the vertical section of the connecting pipe 32 contacts the lower port of the feed funnel 33, and the vertical section of the connecting pipe 32 is clamped on the feed funnel 33 by existing technical means such as snaps, plug-in rods, etc., and then asphalt and gravel are injected into the outer cylinder 27 through the feed funnel 33 and the connecting pipe 32, and are located in the chamber formed between the two adjacent partitions 29, the outer wall of the inner cylinder 26, the inner wall of the outer cylinder 27 and the annular connecting plate 28. When the chamber is filled with asphalt and gravel, the vertical section of the connecting pipe 32 is rotated downward so that the port of the vertical section of the connecting pipe 32 is opposite to the upper port of the feed box 35, and the lower port of the connecting pipe 32 is connected to the upper port of the feed box 35. The asphalt and gravel are injected into the outer cylinder 27, which can not only increase the gravity of the first roller 5, but also make the first roller 5 roll the road surface flat when rolling on the road surface. At the same time, asphalt and gravel are rolled in the outer cylinder 27 during the rolling of the first roller 5, so that the asphalt and gravel are fused with each other to achieve the mixing of the asphalt and gravel. At the same time, since the temperature is high after the asphalt is laid, when the roller rolls the road surface through the first roller 5, the first roller 5 will also carry a lot of heat, so that the first roller 5 transfers the heat to the asphalt in the outer cylinder 27, thereby achieving the effect of keeping the asphalt warm.

[0080] During the rotation of the outer cylinder 27, the annular connecting plate 28 is driven to rotate. When the discharge hole 30 on the annular connecting plate 28 rotates to the highest position, that is, the port of the discharge hole 30 corresponds to the position of the connecting pipe 32, the asphalt between the two adjacent partitions 29 located at the highest position at this time and the gravel mixed therewith slide through the discharge hole 30 and the connecting pipe 32 into the feed box 35, and then slide downward through the feed box 35 to the bottom of the conveying cylinder 34. When the asphalt is detected to have a depression in the road surface by the flatness detector 8, the flatness detector 8 transmits the information to the servo motor 22 and the positioner. After receiving the information, the servo motor 22 drives the screw 21 to rotate, thereby driving the sliding block 23 to move, driving the discharge pipe 10 and the positioner to move. When the sliding block 23 moves to the top of the concave part detected by the flatness detector 8, the positioner The information is transmitted to the servo motor 22, at which time the servo motor 22 stops rotating, the automatic control valve on the discharge pipe 10 opens, and the asphalt slides downward through the discharge pipe 10 to the concave part, thereby filling the concave part. When the automatic control valve is opened, the automatic control valve transmits information to the drive motor 39, and the drive motor 39 drives the auger 37 to rotate through the rotating shaft 36, so that the asphalt at the bottom of the conveying cylinder 34 and the mixed gravel are transported upward to the asphalt storage box 9 through the auger 37, thereby replenishing the asphalt in the asphalt storage box 9, wherein the side walls of the asphalt storage box 9 and the conveying cylinder 34 are provided with heating equipment in the prior art, such as a heating resistor wire, so as to facilitate the insulation of the asphalt in the conveying cylinder 34 and the asphalt storage box 9, and prevent the asphalt in the conveying cylinder 34 and the asphalt storage box 9 from solidifying.
