Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction technology, and in particular to high-frequency vibration roadbed compaction equipment. Background Technology
[0002] The roadbed is an important component of the road structure system, much like the skeleton of the human body, providing solid support for the road surface. It not only bears the dynamic load of vehicles transmitted from the road surface, but also needs to resist the erosion of the natural environment. Embankment roadbeds are constructed by filling soil and stone materials, and it is necessary to ensure that the filling material is compacted evenly. Excavated roadbeds require treatment of the foundation after excavation to prevent the soil from becoming loose. Regardless of the type, the compaction degree, stability and bearing capacity of the roadbed are key indicators to ensure the long-term safe use of the road.
[0003] Traditional roadbed compaction methods mostly rely on static compaction, using the roller's own weight to compact the roadbed. While simple to operate, this method results in shallow compaction depth and poor compaction of deep soil layers. Furthermore, traditional roadbed compaction is extremely unstable during movement, making it difficult to achieve ideal compaction results for different soil types, especially fine-grained clay. While intelligent control functions are currently available on the market, automatically adjusting vibration frequency, amplitude, and travel speed according to different soil conditions and compaction requirements, the poor compaction effect and instability during movement significantly impact work efficiency.

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, when the external mobile device starts to move, since the second arc block is in close contact with the ground, the frame drives the second arc block to start rolling forward, using gravity to compact the ground. Then, the motor in the protective shell is started, driving the centrifugal shaft to rotate, causing the arc block in the groove to rotate, using centrifugal force to improve vibration efficiency.

The outer walls of two such support blocks 201 are firmly fixed to the frame 1 to ensure the stability of the overall structure. On the right side of the outer wall of each support block 201, a rotating shaft 208 is installed via a rotatable connection.

On the right side of the outer wall of the frame 1, a sturdy fixing block 18 is fixedly connected. The right side of the outer wall of the fixing block 18 is tightly connected to the screw 15 by threaded connection, thereby ensuring the stability and adjustability of the entire compaction assembly. In addition, a rubber sleeve 19 is fixedly connected to the right side of the outer wall of the fixing block 18. The rubber sleeve 19 not only provides protection but also reduces vibration and noise during operation.
[0036] Specifically, the compaction component includes a roller 12, whose inner wall is rotatably connected to an arc block 9. The outer wall of the roller 12 has grooves 13 on the front and back, and multiple arc blocks 14 are fixed thereto to enhance friction and improve compaction effect. The fixing block 18 on the right side of the outer wall of the frame 1 is connected to the screw 15 by a thread to ensure that the compaction component is stable and adjustable. The rubber sleeve 19 on the right side of the fixing block 18 can reduce vibration and noise.
[0037] Please see the appendix Figure 4 - Appendix Figure 5 The bottom of the outer wall of the rotating plate 207 is securely connected to two protective sleeves 17. Each protective sleeve 17 has a spring 16 securely connected inside, providing crucial support and cushioning. The inner wall of the rubber sleeve 19 is also securely connected to a connecting post 20. The outer wall of the connecting post 20 has grooves 21 on both its front and rear sides for connection with other components. The bottom of the outer wall of the rubber sleeve 19 is also reliably connected to a connecting rod 22, whose outer wall is slidably connected to a moving ring 23.
[0038] Specifically, two protective sleeves 17 are connected to the bottom of the outer wall of the rotating plate 207, and spring 2 16 is fixed inside them to provide support and buffer. The inner wall of the rubber sleeve 19 is connected to the connecting column 20, and the outer wall of the column is provided with groove 21 at the front and back for connection with other components. Then, the bottom of the outer wall of the rubber sleeve 19 is connected to the connecting rod 22, and the outer wall of the rod is slidably connected to the moving ring 23.
[0039] Working principle: First, when the external equipment starts to move, it drags the frame 1 along. Then, because the multiple arc blocks 14 inside the frame 1 are lower than the frame 1, the center of gravity of the arc blocks 14 will rise and fall periodically when rotating. When the arc blocks 14 land, they generate a huge impact force to compact the ground. When high frequency is required, the motor 6 inside the protective shell 5 can be started. The rotation of the motor 6 drives the centrifugal shaft 8 to rotate. Then, because the centrifugal shaft 8 has a part of the protruding arc block 9 inside the two grinding wheels 12, the presence of the arc block 9 generates centrifugal force when the centrifugal shaft 8 rotates, providing the vibration frequency of the grinding wheel 12 from the inside and improving the compaction efficiency. Then, shock absorbers 10 are connected to both ends of the centrifugal shaft 8. The top and bottom of the shock absorbers 10 are connected to springs 11. During the process of the grinding wheel 12 compacting the ground, the springs 11 reduce the force of the arc blocks 14 bouncing after contacting the ground. The double compaction improves the working efficiency.
[0040] Support blocks 201 are connected to both the left and right sides of frame 1. When frame 1 moves, support blocks 201 move with it and are connected to protective frame 202. A rotating shaft 203 is connected to the inner wall of protective frame 202. Since protective frame 202 moves with support blocks 201, rotating shaft 203 rotates, which in turn drives gear 204 to rotate, causing moving plate 205 to rotate, increasing stability during compaction. On the right side of support blocks 201, rotating plate 207 is connected to rotating shaft 208. When arc block 14 compacts the ground, moving plate 205 is also affected. When arc block 14 bounces up after compacting the ground, rotating plate 207 flips up due to rotating shaft 208 and moves with it, reducing vibration and achieving smoother movement.
