Description

Technical Field

[0001] This utility model belongs to the technical field of highway construction, specifically relating to a roadbed paving device for highway base construction. Background Technology

[0002] In recent years, roadbed leveling devices in highway construction have become key equipment in modern road construction. They are mainly used for leveling operations after roadbed filling to ensure that the flatness, density, and slope of the base layer meet the engineering design requirements. These devices typically include core components such as laser or GPS-controlled automatic leveling systems and hydraulically driven scrapers or vibrating beams. They can efficiently handle fillers such as sand, gravel, and stabilized soil, significantly reducing errors caused by traditional manual leveling and improving construction efficiency and quality.

[0003] Currently, during roadbed paving operations, vibrating beams or scrapers may experience resonance due to insufficient structural stiffness or poor damping characteristics under high-frequency vibration or specific operating speeds. This can lead to abnormally increased local amplitude of the equipment, causing not only regular ripples on the paved surface and affecting flatness, but also accelerating the loosening of connectors and structural fatigue.

[0027] Example

[0028] Reference Figures 1-4 This embodiment of the present invention provides a roadbed leveling device for highway construction, comprising:

[0029] The laying unit 100 includes a vibrating beam 110 and a buffer assembly 120 disposed on the outside of the vibrating beam 110;

[0030] The seismic unit 200 includes a shell 210 fixedly installed on the outside of the vibrating beam 110, a cover plate 220 movably installed on the outside of the shell 210, a bearing 230 fixedly installed on the outside of the cover plate 220, and an aluminum honeycomb core plate 240 fixedly installed in the inner cavity of the shell 210.

[0031] The vibration beam 110 and the buffer assembly 120 work together to effectively disperse the impact load during the leveling operation and reduce the risk of beam resonance. The seismic unit 200 adopts a combination design of aluminum honeycomb core panel 240 and shell 210, which not only improves local stiffness, but also absorbs high-frequency vibration through the damping characteristics of the honeycomb structure, thereby reducing the overall vibration amplitude of the equipment and extending its service life.

[0032] Specifically, the seismic unit 200 also includes a shock-absorbing spring 250 fixedly installed on the outside of the aluminum honeycomb core panel 240, a rigid support plate 260 fixedly installed on the end of the shock-absorbing spring 250, a flexible connecting plate 270 fixedly installed on the outside of the rigid support plate 260, and a connecting screw 280 fixedly installed in the center of the outside of the housing 210. The flexible connecting plate 270 is fixedly installed at an inclined angle, and the end of the flexible connecting plate 270 is fixedly connected to the inner wall of the housing 210.

[0033] The damping spring 250 and the rigid support plate 260 form a two-stage vibration reduction system to further suppress vibration transmission. The flexible connecting plate 270 compensates for the slight deformation of the vibration beam 110 through elastic deformation to avoid stress concentration. The connecting screw 280 enhances the integrity of the housing 210 and prevents the connection from loosening due to high-frequency vibration. The inclined flexible connecting plate 270 can directionally guide the vibration energy to diffuse to the inner wall of the housing 210, preventing the energy from being transmitted back to the vibration beam 110. Its fixed connection design with the inner wall of the housing 210 can also improve the stability of the anti-vibration unit 200 and ensure that the vibration reduction effect is long-lasting and effective.

[0034] Furthermore, the laying unit 100 also includes a connecting bend plate 130 fixedly installed at the bottom of the vibrating beam 110, a reinforcing rib plate 140 fixedly installed on the outside of the connecting bend plate 130, a load-bearing component 150 disposed on the outside of the connecting bend plate 130, and a scraper 160 fixedly installed on the outside of the connecting bend plate 130.

[0035] The combination of the connecting bending plate 130 and the stiffening plate 140 significantly improves the bending stiffness of the bottom of the vibrating beam 110; the bearing component 150 disperses the working resistance of the scraper 160 through multi-point support, reduces the local load on the vibrating beam 110, and thus improves the flattening uniformity.

[0036] Preferably, the buffer assembly 120 includes a housing 121 fixedly installed on the outside of the connecting bend plate 130, a fixing block 122 fixedly installed in the inner cavity of the housing 121, and a damping damper 123 fixedly installed on the outside of the fixing block 122. The buffer assembly 120 also includes a limiting slider 124 fixedly installed on the end of the damping damper 123, a groove 125 opened on the outside of the limiting slider 124, and a limiting strip 126 fixedly installed on the inner wall of the housing 121. The limiting slider 124 is movably locked on the outside of the limiting strip 126 through the groove 125.

[0037] Among them, the damping damper 123 of the buffer assembly 120 can quickly dissipate vibration energy, while the rigid connection between the fixed block 122 and the housing 121 ensures the positioning accuracy of the damping damper 123 and avoids displacement failure due to long-term vibration, thus taking into account both immediate vibration reduction and long-term reliability. The sliding cooperation between the limit slider 124 and the limit bar 126 allows the damping damper 123 to adaptively move within a limited range, which avoids rigid jamming and constrains its movement trajectory through the slide groove 125, preventing the damping damper 123 from leaving the working position due to vibration overload.

[0038] Furthermore, the load-bearing assembly 150 includes a vertical plate 151 fixedly installed on the outside of the connecting bend plate 130, a support diagonal rod 152 fixedly installed on the outside of the vertical plate 151, a connecting frame 153 fixedly installed on the outside of the support diagonal rod 152, and a support rod 154 fixedly installed at the bottom of the connecting frame 153.

[0039] Among them, the support diagonal rod 152 and the connecting frame 153 form a triangular stable structure, which enhances the lateral bearing capacity of the vertical plate 151; the support rod 154 directly transmits the working pressure of the scraper 160 to the frame, reducing the bending deformation of the vibration beam 110, thereby improving the leveling accuracy and equipment durability.

[0040] During use, the vibrating beam 110 generates high-frequency vibration under drive, which drives the scraper 160 to spread and compact the roadbed material. At this time, the buffer component 120 absorbs and buffers the vibration impact through the damping damper 123 and the limiting slider 124. At the same time, the vibration energy is transmitted to the anti-vibration unit 200 through the vibrating beam 110, where the high-frequency vibration is absorbed by the aluminum honeycomb core panel 240, and the shock-absorbing spring 250 and the flexible connecting plate 270 work together to further dissipate the energy. The bearing component 150 distributes the working pressure evenly to the frame through the support diagonal bar 152 and the support rod 154, thereby effectively suppressing the transmission of vibration while ensuring the leveling accuracy and ensuring the stable operation of the equipment.

[0041] In summary, by combining the vibration beam 110 with the buffer assembly 120 to disperse impact loads and reduce resonance risk, the seismic unit 200 uses aluminum honeycomb core panels 240 and damping springs 250 to form a multi-stage vibration reduction system, significantly suppressing vibration transmission and improving equipment stability. The connecting bending plate 130 and the reinforcing rib plate 140 enhance structural rigidity, and the load-bearing assembly 150 optimizes stress distribution, reducing local deformation of the vibration beam 110. The damping damper 123 of the buffer assembly 120, in conjunction with the limiting slider 124, adaptively adjusts to ensure a long-lasting and reliable vibration reduction effect. The overall structure, while ensuring paving accuracy, significantly extends the service life of the equipment, making it suitable for high-intensity, high-frequency highway subgrade construction and effectively solving the vibration and impact problems during roadbed paving.
