Description

Technical Field

[0001] The present invention relates to the technical field of road construction, in particular to road compacting equipment for road construction and a construction method thereof. Background Art

[0002] Compacting the roadbed and pavement during road construction is a core process for ensuring road durability and stability. Traditional compaction equipment typically uses vibratory rollers or rammers for layered compaction. However, existing technologies still have significant drawbacks in practical applications: conventional equipment first requires mechanical leveling of the road surface, followed by layer-by-layer compaction using rollers or handheld rammers. This multi-machine collaboration prolongs construction cycles, and existing rammers often rely on motors to directly drive the rammer's vertical motion. This results in limited energy per impact and poor compaction effectiveness for deep roadbeds. Summary of the Invention

[0003] The object of the present invention is to provide a road compacting device for road construction and a construction method thereof, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a road compacting device for road construction, comprising a main body, a roller provided at the bottom of the rear end of the main body, a flattening assembly provided at the front end of the main body, and a compacting assembly provided at the middle portion of the main body, wherein the flattening assembly abuts against a road surface and moves horizontally under the drive of a first motor, thereby flattening the road surface;

[0005] The ramming assembly includes a ramming piece, an impact block and a power assembly. A guide opening is provided at the bottom end of the middle portion of the main body in the vertical direction. The ramming piece is slidably arranged in the guide opening. The power assembly is arranged at the top of the main body. The power assembly passes through the main body and extends to be connected to the top end of the ramming piece. The ramming piece is driven up and down by the power assembly to compact the road surface. An impact groove is provided at the top end of the ramming piece. The depth of the impact groove is at least half of the height of the ramming piece. A fixed block adapted to the impact groove is provided on the inner wall of the top end of the guide opening. When the ramming piece rises to the highest point, the fixed block is located in the impact groove. The impact block is connected to the bottom surface of the fixed block by a plurality of first springs. A locking assembly adapted to the impact block is provided on the fixed block. When the ramming piece rises, it drives the impact block to rise synchronously and compress the first spring. When the impact block rises to the highest point, the locking assembly abuts against it to limit and fix it. When the ramming piece falls to the lowest point, its top end contacts the locking assembly and is unlocked, so that the impact block loses its limiting force and impacts the ramming piece under the elastic force of the first spring.

[0006] The gear train is equipped with a gear that is adapted to move along the gear train, and the gear train is equipped with a gear that is adapted to move along the gear train, and a gear that is adapted to move along the gear train to move along the gear train.

[0007] In this embodiment, the support rod is slidably assembled on the slider along the vertical direction, a limit block is provided at the top end of the support rod, and a third spring is connected between the limit block and the top end of the slider.

[0008] In this embodiment, the locking assembly includes a plurality of locking blocks, and the side wall of the fixed block is provided with a plurality of fixing openings at equal intervals, and the fixing openings are connected to a fourth spring, and the other end of each of the fourth springs is installed with the locking block, and the top inner wall of the impact block is provided with a plurality of limiting openings corresponding to each locking block. When the impact block rises to the top, the locking block is stuck in the limiting opening, and the top surface of the impact block is provided with a plurality of unlocking openings corresponding to the limiting openings, and the limiting openings are connected to the unlocking openings. A push block is slidably provided in the limiting opening, and the top end of the impact groove extends inward to form an annular block, and the bottom end of the annular block is provided with a plurality of pressure blocks corresponding to the unlocking openings. When the pressure block is pressed down, it will squeeze the push block to move to the side close to the fixed block.

[0009] In this embodiment, the power assembly includes several support rods, a support plate, a connecting seat and a driving rod. Several of the support rods are distributed at the bottom end of the support plate. The bottom end of the support rod slides through the top of the main body and extends to connect with the rammer. The connecting seat is arranged in the middle of the top of the support plate. Support frames are provided on both the front and rear sides of the top of the main body. The inner ends of the two support frames are rotatably provided with supports, and one of the supports is driven to rotate by the second motor. An eccentric rod is connected between the supports on both sides, and the two ends of the driving rod are hingedly connected to the eccentric rod and the connecting seat respectively.

[0010] In this embodiment, a handrail is fixedly connected to the top of the rear end of the main body.

[0011] The present invention also provides a construction method applied to the above-mentioned road compaction equipment, comprising the following steps:

[0012] S1. Clean up debris in the construction area, check the original smoothness of the road surface, and perform manual pre-treatment on significantly uneven areas;

[0013] S2. After the main body moves to the target area, the first motor drives the connecting shaft, and the engagement of the half gear and the rack pushes the pressing plate forward periodically to perform leveling. The second spring resets the plate to achieve continuous operation, and at the same time, a rotating load block applies dynamic vertical pressure to the pressing plate.

[0014] S3. After the screeding work is completed, the compacting plate remains in the forwardmost position, the power assembly drives the rammer to rise to the top, the impact block locks and compresses the spring to store energy, and then drives the rammer to fall and compact the road surface. After the rammer falls, the locking assembly is triggered to unlock, and the first spring releases energy to drive the impact block to impact at high speed, completing further vibration after compaction;

[0015] S4. The power assembly continuously drives the rammer to move up and down, thereby continuously compacting the road surface.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention achieves a seamless connection between pavement pretreatment and deep compaction through the coordinated work of the flattening component and the tamping component. The horizontal reciprocating scraping of the flattening plate eliminates the accumulation of loose materials, while the dynamic pressure of the load-bearing block completes the initial pre-compression; the dual impact mechanism of the tamping component (main tamping + spring release impact) directly performs high-intensity compaction after scraping, avoiding the multiple round-trip process intervals of traditional equipment and significantly shortening the construction period.

[0018] 2. The present invention preferentially destroys the initial structure of the material through the vertical impact of the rammer, forming a dense base layer. The spring energy stored in the impact block is then released to generate a secondary shock wave, which penetrates into the gaps in the base layer, eliminates tiny gaps, and improves the overall density and uniformity. It is particularly suitable for anti-settling treatment of clay or mixed materials.

[0019] 3. The locking block and the limit opening of the locking assembly of the present invention are triggered separately. The impact block is unlocked only when the rammer is pressed into place, avoiding energy waste or structural damage caused by false triggering, and ensuring a delay between the two impact actions. The synergistic effect of the rammer compacting in advance and the delayed reinforcement of the impact block significantly improves the composite impact energy efficiency.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, a road compacting device for road construction includes a main body 1, a roller 2 is provided at the bottom of the rear end of the main body 1, a flattening assembly is provided at the front end of the main body 1, and a compacting assembly is provided in the middle of the main body 1. The flattening assembly abuts against the road surface and moves horizontally under the drive of a first motor 39, thereby flattening the road surface;

[0031] The compacting assembly includes a ramming piece 3, an impact block 4 and a power assembly. A guide port 5 is provided at the bottom middle end of the main body 1 in the vertical direction. The ramming piece 3 is slidably arranged in the guide port 5. The power assembly is arranged at the top of the main body 1. The power assembly passes through the main body 1 and extends to be connected to the top of the ramming piece 3. The ramming piece 3 is driven up and down by the power assembly to compact the road surface. An impact groove 6 is provided at the top of the ramming piece 3. The depth of the impact groove 6 is at least half of the height of the ramming piece 3. A fixed block 7 adapted to the impact groove 6 is provided on the inner wall of the top of the guide port 5. When the ramming piece 3 is compacted, the impact groove 6 is provided. When the striking piece 3 rises to the top, the fixed block 7 is located in the impact groove 6, and the impact block 4 is connected to the bottom surface of the fixed block 7 through several first springs 8. The fixed block 7 is provided with a locking assembly adapted to the impact block 4; when the striking piece 3 rises, it drives the impact block 4 to rise synchronously and compresses the first spring 8. When the impact block 4 rises to the top, the locking assembly abuts against it to limit and fix it. When the striking piece 3 drops to the lowest point, its top contacts the locking assembly and is unlocked, so that the impact block 4 loses its limiting force and impacts the striking piece 3 under the elastic force of the first spring 8.

[0032] In this embodiment, the flattening assembly includes a flattening plate 9, a connecting shaft 10, a pair of output wheels 11 and a pair of weight blocks 12. The connecting shaft 10 is rotatably arranged at the front end of the main body 1, and the two ends of the connecting shaft 10 extend out of both sides of the main body 1. Both ends of the connecting shaft 10 are provided with output wheels 11 and half gears 13. One side of the output wheel 11 is connected to the weight block 12 with an arc structure. The left and right ends of the main body 1 are provided with a movable groove 15. Each movable groove 15 is provided with a slide rod 16 in the horizontal direction. The slide rod 16 is slidably equipped with a slider 17, and the slider 17 is provided with a support rod 1 8. The bottom end of the support rod 18 is connected to both sides of the rear end of the flattening rod. A second spring 19 is sleeved on the slide bar 16 and the second spring 19 is connected between the inner wall of the movable groove 15 and the slider 17. Racks 20 are provided on both sides of the top surface of the flattening plate 9. The half gear 13 rotates to engage with the rack 20 and drives the flattening plate 9 to move forward. When the load block 12 rotates to the bottom end, it abuts against the flattening plate 9 and applies pressure. The support rod 18 is slidably assembled on the slider 17 in the vertical direction. A limit block 21 is provided at the top of the support rod 18. A third spring 22 is connected between the limit block 21 and the top of the slider 17.

[0033] The first motor 39 drives the connecting shaft 10 to drive the half gear 13 to rotate, meshing with the racks 20 on both sides of the pressure plate 9, pushing the pressure plate 9 to move forward. When the half gear 13 rotates to the other side, the gear leaves the rack 20. After the pressure plate 9 loses the limiting force of the half gear 13, it moves backward and resets under the elastic force of the second spring 19, thereby realizing the horizontal reciprocating movement of the pressure plate 9 through the cooperation of the half gear 13 and the second spring 19 to perform preliminary scraping of the road surface. In the process of horizontal movement of the pressure plate 9, the rotation of the connecting shaft 10 synchronously drives the output wheel 11 to rotate. When the load block 12 on the output wheel 11 rotates to abut against the top surface of the pressure plate 9, its own weight is directly applied to the road surface through the pressure plate 9, thereby enhancing the local pressure strength. The design of the sliding support rod 18 and the third spring 22 allows the pressure plate 9 to be adaptively adjusted through the extension and retraction of the support rod 18 when encountering undulations in the road surface, thereby avoiding damage to the equipment due to rigid impact.

[0034] In this embodiment, the locking assembly includes a plurality of locking blocks 23, and a plurality of fixing openings 24 are evenly spaced on the side wall of the fixed block 7. A fourth spring 25 is connected to the fixing opening 24, and the other end of each fourth spring 25 is installed with a locking block 23. The top inner wall of the impact block 4 is provided with a plurality of limiting openings 26 corresponding to each locking block 23. When the impact block 4 rises to the top, the locking block 23 is snapped into the limiting opening 26. The top surface of the impact block 4 is provided with a plurality of unlocking openings 27 corresponding to the limiting openings 26. The limiting openings 26 are connected to the unlocking openings 27. A push block 28 is slidably provided in the limiting opening 26. The top end of the impact groove 6 extends inward to form an annular block 29. The bottom end of the annular block 29 is provided with a plurality of pressing blocks 30 corresponding to the unlocking openings 27. When the pressing block 30 is pressed down, it squeezes the push block 28 to move to the side close to the fixed block 7;

[0035] When the ramming member 3 rises to its highest point, it simultaneously drives the impact block 4 to rise. After the impact block 4 rises to its highest point, the locking block 23 is engaged in the limit opening 26 under the action of the fourth spring 25, thereby fixing the impact block 4. When the ramming member 3 rushes down to its lowest point, it vertically impacts the road surface to complete the initial tamping. At the same time, the pressure block 30 at its top presses down into the unlocking opening 27 and pushes the pushing block 28 outward, thereby pushing the locking block 23 out of the limit opening 26 and unlocking the impact block 4.

[0036] At this time, the first spring 8 releases the stored energy, driving the impact block 4 to hit the top of the rammer 3 at high speed, forming a secondary shock wave, significantly enhancing the compaction depth (the rammer 3 will first contact and compact the ground before unlocking the impact block 4). The rammer 3 moves back and forth up and down, thereby continuously compressing and releasing the first spring 8, so that the impact block 4 performs a secondary impact after each rammer 3 strikes.

[0037] In this embodiment, the power assembly includes a plurality of support rods 31, a support plate 32, a connecting seat 33 and a driving rod 34. The plurality of support rods 31 are distributed at the bottom end of the support plate 32. The bottom end of the support rod 31 slides through the top of the main body 1 and extends to connect with the ramming member 3. The connecting seat 33 is provided at the middle part of the top of the support plate 32. Support frames 35 are provided on both the front and rear sides of the top of the main body 1. The inner ends of the two support frames 35 are rotatably provided with supports 36, and one of the supports 36 is driven to rotate by the second motor 40. An eccentric rod 37 is connected between the supports 36 on both sides. The two ends of the driving rod 34 are hingedly connected to the eccentric rod 37 and the connecting seat 33 respectively.

[0038] The second motor 40 drives the support 36 to drive the eccentric rod 37 to rotate. The two ends of the eccentric rod 37 are fixed by the support frame 35 to form a stable rotating axis. The two ends of the driving rod 34 are respectively hinged to the eccentric rod 37 and the connecting seat 33, and the eccentric rotational motion is converted into a vertical reciprocating motion of the support plate 32, thereby driving the ramming piece 3 to move up and down through the support rod 31. The distributed support rods 31 ensure that the impact force is evenly transmitted.

[0039] In this embodiment, an armrest 38 is fixedly connected to the top of the rear end of the main body 1. When the main body 1 is moved, the staff holds the armrest 38 and then presses the armrest 38 downward. The roller 2 is used as a fulcrum to make the front end of the main body 1 tilt upward, thereby lifting the pressing plate 9 off the ground. Then, the main body 1 can be pushed to move by the roller 2. After moving to the target area, the pressing plate 9 is lowered so that it contacts the ground.

[0040] This embodiment also provides a construction method applied to the above-mentioned road compaction equipment, comprising the following steps:

[0041] S1. Clean up debris in the construction area, check the original smoothness of the road surface, and perform manual pre-treatment on significantly uneven areas;

[0042] S2. After the main body 1 moves to the target area, the first motor 39 is started to drive the connecting shaft 10. The engagement of the half gear 13 and the rack 20 pushes the pressing plate 9 forward periodically to perform the scraping. The second spring 19 is reset to achieve continuous operation. At the same time, the rotating load block 12 is used to apply dynamic vertical pressure to the pressing plate 9.

[0043] S3. After the screeding work is completed, the pressing plate 9 remains in the position moved to the front, the power assembly drives the rammer 3 to rise to the top, the impact block 4 is locked and the spring is compressed to store energy, and then the rammer 3 is driven to fall to compact the road surface. After the rammer 3 falls, the locking assembly is triggered to unlock, and the first spring 8 releases energy to drive the impact block 4 to impact at high speed, completing further vibration after compaction;

[0044] S4. The ramming member 3 is continuously driven to move up and down by the power assembly, thereby continuously compacting the road surface.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
