Description

Technical Field

[0001] This invention belongs to the field of road construction technology, and in particular relates to a roadbed compaction device for road construction. Background Technology

[0002] A roadbed is a strip-shaped structure built according to the route location and certain technical requirements, serving as the foundation for the pavement. It is the basis of railways and highways, and is a linear structure constructed of earth or stone. Roadbeds are built under favorable geological, hydrological, and climatic conditions. Based on materials, roadbeds can be divided into three types: earth roadbeds, stone roadbeds, and earth-stone roadbeds.

[0003] The roadbed needs to be compacted during the laying process to ensure the stability of the subsequent road surface. Most existing roadbed compaction devices use rollers to roll and compact the roadbed, which is a relatively simple compaction method and has limited compressive strength, which is not conducive to the compaction of the roadbed.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0025] like Figures 1-6As shown in the preferred embodiment of the present invention, a roadbed compaction device for road construction includes a base 1, a groove 4 in the middle of the base 1, multiple sets of spaced support plates 2 fixedly installed on the base 1, and multiple sets of parallel traveling rollers 3 rotatably mounted on the support plates 2, and side plates 5 located on both sides of the groove 4 fixedly installed on the base 1, a rotating shaft 6 rotatably mounted on the side plates 5, a power assembly 32 for driving the rotating shaft 6 to rotate on the side plates 5, both ends of the rotating shaft 6 penetrating the side plates 5, and multiple sets of linearly spaced mounting cylinders 7 fixedly installed on the rotating shaft 6, a second slider 11 slidably installed inside the mounting cylinder 7, and a support rod 13 extending out of the mounting cylinder 7 fixedly installed on the second slider 11, the axis of the support rod 13 being on the same straight line as the axis of the mounting cylinder 7. A mounting frame 14 is fixedly installed on one end of the support rod 13 located outside the mounting cylinder 7. A compaction roller 15 is rotatably installed inside the mounting frame 14. The axis of the compaction roller 15 is parallel to the axis of the traveling roller 3. An electromagnet 10 with a ring structure that works in conjunction with the second slider 11 is fixedly installed inside the mounting cylinder 7. A buffer assembly 33 that works in conjunction with the second slider 11 is provided inside the mounting cylinder 7. A telescopic member 24 located on one side of the groove 4 is fixedly installed on the base 1. A lifting frame 25 is fixedly installed at the output end of the telescopic member 24. Multiple sets of horizontal shafts 26 parallel to the traveling roller 3 are rotatably installed inside the lifting frame 25. Cutting blades 27 and scrapers 28 are fixedly installed on the horizontal shafts 26 respectively. A rotating assembly 34 that drives the horizontal shafts 26 to rotate is provided on the lifting frame 25.

[0026] The cutting blades 27 are arranged in multiple groups and evenly distributed on the horizontal axis 26. Each group of cutting blades 27 has multiple blades, and the multiple cutting blades 27 are linearly spaced along the length of the horizontal axis 26.

[0027] Multiple scrapers 28 are provided and evenly distributed on another set of horizontal axes 26, and the length direction of the scrapers 28 is set at an angle to the length direction of the horizontal axes 26.

[0028] In practical application, the present invention uses an external power device to move the base 1 to the roadbed to be compacted. During compaction, the power component 32 applies a force to drive the rotating shaft 6 to rotate simultaneously from both ends, causing the rotating shaft 6 to rotate slowly. The rotation of the rotating shaft 6 causes the compaction rollers 15 on both sides to move continuously. When the rotation of the rotating shaft 6 causes the mounting cylinder 7 to rotate, so that one side of the compaction roller 15 is above the mounting cylinder 7, the compaction roller 15, under the action of gravity, pushes the second slider 11 to move inside the mounting cylinder 7 through the support rod 13, so that the second slider 11 contacts the buffer component 33. Thereafter, the second slider 11 remains in contact with the buffer component 33. As the upward tilt angle of the mounting cylinder 7 increases, the separation along the length of the support rod 13 increases. The large size of the second slider 11 causes it to move within the mounting cylinder 7. At this point, the second slider 11 contacts the electromagnet 10. The buffer assembly 33 causes the second slider 11 to slowly move to the position of the electromagnet 10 and contact it, preventing the second slider 11 from impacting the electromagnet 10 during its movement and improving the stability of the device. The electromagnet 10 is then energized, causing it to attract the second slider 11. The rotating shaft 6 continues to drive the compaction roller 15 to rotate. When the mounting cylinder 7 rotates to a vertical position pointing towards the ground, the electromagnet 10 is de-energized. Under the influence of gravity and the energy released from the buffer assembly 33, the compaction roller 15 accelerates downwards. Upon contact with the roadbed, the compaction roller 15 impacts and compacts the roadbed. Under the acceleration... It can apply a compressive force exceeding the weight of the compaction roller 15 itself, thereby increasing the compressive force on the roadbed, making the roadbed harder, improving the compaction effect, and benefiting subsequent road paving. As the rotating shaft 6 continues to rotate, the second slider 11 can move downward inside the mounting cylinder 7, allowing the compaction roller 15 to roll a certain distance on the roadbed. At this time, the roadbed near the impact position is compacted again by the weight of the compaction roller 15 itself. The continuous rotation of the rotating shaft 6 allows the compaction roller 15 to continuously perform impact compaction and rolling compaction of the roadbed. When the base 1 moves, the telescopic component 24 drives the lifting frame 25 to move downward to a suitable position, so that the lower ends of the cutting blade 27 and scraper 28 are close to the roadbed. At the same time, the rotating component 34 drives the horizontal shaft 26. The rotation causes the cutting blades 27 and scraper 28 to rotate. The cutting blades 27 cut through protruding parts of the roadbed, and the scraper 28 then flattens these protrusions, achieving rapid removal and flattening. The rear traveling roller 3 then compacts the roadbed again, ensuring a smooth surface and a firm foundation. The compaction roller 15 continuously impacts and rolls the roadbed, with the traveling roller 3 providing additional compaction. This multi-mode and multiple-stage compaction of the roadbed is achieved. Furthermore, the compaction roller 15 can apply a pressure exceeding its own weight, increasing the compressive strength on the roadbed, making it firmer, and improving the compaction effect, which is beneficial for subsequent road paving.It allows for the rapid removal and leveling of protruding areas after compaction, followed by recompaction, ensuring a smooth roadbed surface and a firm roadbed, which is beneficial for use.

[0029] In one embodiment of the present invention, the telescopic member 24 is an electric telescopic rod, but it can also be other components such as a hydraulic cylinder that can actively change length. The electric telescopic rod drives the lifting frame 25 to move up and down.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the power assembly 32 includes a gear ring 22, and multiple sets of vertical rods 23 distributed along its radial direction are fixedly installed inside the gear ring 22. The end of the vertical rod 23 away from the gear ring 22 is fixedly connected to the rotating shaft 6, and the axis of the gear ring 22 coincides with the axis of the rotating shaft 6.

[0031] The power assembly 32 also includes a power shaft 19, which is rotatably mounted on the side plate 5 and parallel to the rotating shaft 6. A transmission gear 21 that meshes with the gear ring 22 is fixedly mounted on the end of the power shaft 19 away from the side plate 5.

[0032] A mounting plate 16 is fixedly installed at a distance from the base 1 on the side plate 5. A worm gear 17 with a different plane perpendicular to the power shaft 19 is rotatably mounted on the mounting plate 16. The worm gear 17 meshes with a worm wheel 20 fixedly mounted on the power shaft 19. One end of the worm gear 17 is fixedly connected to a first rotating power component 18 located on the mounting plate 16.

[0033] In practical application, the first rotating power component 18 drives the worm 17 to rotate, and the worm 17 drives the power shaft 19 to rotate through the meshing worm wheel 20. Since the gear ring 22 is fixedly installed on the rotating shaft 6 through the vertical rod 23 and the axis of the gear ring 22 coincides with the axis of the rotating shaft 6, the power shaft 19 drives the rotating shaft 6 to rotate through the meshing transmission gear 21 and the gear ring 22. The rotation of the rotating shaft 6 can realize the change of the position of the compaction roller 15. The self-locking of the worm wheel 20 and the worm 17 can prevent the power shaft 19 from rotating unnecessarily, prevent the power shaft 19 from applying an active rotational force to the first rotating power component 18, prevent the first rotating power component 18 from being damaged, and ensure the stability of the rotating shaft 6 when it is stationary. The gear ring 22 increases the driving force arm on the rotating shaft 6, thereby reducing the driving force for driving the rotating shaft 6 to rotate, which is beneficial to use.

[0034] In one embodiment of the present invention, the first rotating power component 18 is a first motor, but it can also be a hydraulic motor or other components capable of outputting rotational power. The first motor drives the rotating shaft 6 to rotate through components such as the power shaft 19, the gear ring 22 and the transmission gear 21, thereby realizing the change of the position of the compaction roller 15.

[0035] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the buffer assembly 33 includes an elastic element 8. One end of the elastic element 8 is fixedly mounted on the rotating shaft 6 and located inside the mounting cylinder 7. The end of the elastic element 8 away from the rotating shaft 6 is fixedly connected to a first slider 9. The outer surface of the first slider 9 slides in contact with the inner wall of the mounting cylinder 7.

[0036] The buffer assembly 33 also includes a push rod 12, which is fixedly mounted on the second slider 11 and located on the surface of the second slider 11 near the electromagnet 10. The push rod 12 passes through the middle of the electromagnet 10.

[0037] In practical application, when the rotating shaft 6 rotates and drives the mounting cylinder 7 to rotate, causing the compaction roller 15 to be positioned above the mounting cylinder 7, the compaction roller 15, under the action of gravity, pushes the second slider 11 downward within the mounting cylinder 7 via the support rod 13. This allows the push rod 12 to pass through the middle of the annular electromagnet 10 and contact the first slider 9. The push rod 12 pushes the first slider 9 downward and compresses the elastic element 8, thereby absorbing the impact force of the second slider 11 moving downward through the compression of the elastic element 8. Afterward, the push rod 12 contacts the first slider 9. As the upward tilt angle of the mounting cylinder 7 increases, the push rod 12 pushes the first slider 9 downward smoothly. When the mounting cylinder 7 is in a vertical state, the second slider 11 contacts the electromagnet 10, thus achieving smooth contact between the second slider 11 and the electromagnet 10, avoiding impact on the electromagnet 10 during the movement of the second slider 11, and improving the stability of the device.

[0038] In one embodiment of the present invention, the elastic element 8 is a spring, but it can also be other elastic components such as a bouncy ball. The spring compression absorbs the impact force when the second slider 11 moves, thereby avoiding the impact of the second slider 11 on the electromagnet 10 when it moves, and improving the stability of the device.

[0039] like Figure 5 As shown, in a preferred embodiment of the present invention, the rotating assembly 34 includes a second rotating power member 29, which is fixedly mounted on the lifting frame 25 and the output shaft of the second rotating power member 29 is parallel to the horizontal axis 26. A first gear 30 is fixedly mounted at the end of the output shaft of the second rotating power member 29, and a second gear 31 fixedly mounted on the horizontal axis 26 is meshed on both sides of the first gear 30.

[0040] In practical application, the second rotating power component 29 drives the first gear 30 to rotate, and the first gear 30 drives the two sets of horizontal shafts 26 to rotate simultaneously through the second gear 31 meshing on both sides, thereby realizing the cutting and scraping of the protruding parts of the roadbed surface.

[0041] In one embodiment of the present invention, the second rotating power component 29 is a second motor, or it can be a hydraulic motor or other component capable of outputting rotational power. The second motor drives the horizontal shaft 26 to rotate, thereby achieving the cutting and scraping of protruding parts on the roadbed surface.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
