Summary of the Invention

[0013] This invention provides a road paving device for roads and bridges. It has the following beneficial effects: 1. This invention, by setting up a compaction mechanism, allows water to flow into the bottom of the inner wall of the water storage chamber through the second water channel, thereby realizing the function of real-time weighting of the compaction roller during the paving and rolling process, avoiding the traditional compaction roller which can only be watered when stopped, thus affecting its working efficiency. 2. The present invention sets up a compaction mechanism, in which the inner cavity of the compaction roller is divided into multiple independent water chambers by a circular partition plate. Each water chamber is connected by a flow channel. The space of the flow channel is limited, thereby effectively suppressing the inertial displacement of the water body when the water flows laterally rapidly, and ensuring the dynamic balance of water volume in each water chamber. 3. By setting up a compaction mechanism, the lifting float floats synchronously with the rise and fall of the water level, covering the water surface. This effectively isolates the water from shaking when the compaction roller rolls, sways, and turns. The lifting float slides in the annular groove opened in the inner wall of the fixed limiting ring to complete the synchronous lifting and lowering displacement of the lifting float with the liquid level, ensuring the uniformity and stability of the paved and compacted road surface. 4. By setting up a compaction mechanism, the first telescopic rod is positioned slightly to the left of the bottom of the lifting float, which provides more counterweight to the left side of the lifting float. This ensures that even when the compaction roller rolls and causes the lifting float to move, generating an eccentric force that is applied to the water inside the float and the swaying of the lifting float, the first telescopic rod can effectively counteract this force, thereby maintaining the overall center of gravity stability and keeping the lifting float as balanced as possible. 5. By setting up a compaction mechanism, the lifting float gets closer to the top of the sensor and the top of the inner wall of the compaction roller as more water is injected. This allows the distance sensor to automatically identify and detect the distance between the rectangular sliders above, providing intelligent feedback on the real-time filling status of the water cavity and providing operators with a basis for dynamic counterweight calibration.

[0016] Example 1: Please refer to Figure 1-3 The present invention provides a technical solution: a road paving device for road bridges, including a road compactor 2, a connector 1 fixedly connected to one side of the road compactor 2, a fixed frame 6 fixedly connected to one side of the connector 1, water pumps 5 fixedly connected to both sides of the fixed frame 6, and a compaction mechanism 3 provided inside the fixed frame 6. Compaction mechanism 3 includes: The compaction roller 301 has hollow rotating sleeves 302 fixedly connected to both sides of the compaction roller 301. The other side of the hollow rotating sleeve 302 is rotatably connected to the inner wall of the fixed frame 6. The inner wall of the hollow rotating sleeve 302 is provided with a first water passage groove 303. The lifting float 309 is a plate-shaped structure and is installed in the inner wall of the compaction roller 301. The inner wall of the compaction roller 301 is provided with a second water channel 304, which is connected to the interior of the first water channel 303 and the interior of the second water channel 304 is connected to the interior of the compaction roller 301.

[0017] When in use, the operator drives the road compactor 2 to push the fixed frame 6 and the compaction roller 301 smoothly on the road surface through the connector 1, and uses the weight of the compaction roller 301 to compact the road surface after paving.

[0018] Example 2: Please refer to Figure 1-6Based on Embodiment 1, this invention provides a technical solution: In the road paving construction process, the compaction roller is a crucial piece of equipment, its function being to compact the paved road surface material to improve the smoothness and strength of the road surface. Traditional methods of weighting the compaction roller typically involve manually or through a specific water-adding device injecting water into the roller when work stops, thereby increasing the roller's weight and improving the compaction effect. However, this traditional method has significant drawbacks. On the one hand, frequent stops for water addition during operation greatly affect the continuity and efficiency of construction, extending the overall road paving period. On the other hand, during dynamic operations such as rolling and turning, the water injected inside the compaction roller can cause a shift in the center of gravity due to swaying. Especially during turns, under centrifugal force, the water will tilt to one side, resulting in uneven pressure distribution on the road surface. This leads to over-compaction in some areas and under-compaction in others, severely affecting the paving quality and causing problems such as poor road surface smoothness and uneven strength, increasing the cost and difficulty of subsequent road maintenance. Therefore, how to achieve real-time weighting of the compaction roller during operation, while effectively solving the problems of center of gravity shift and uneven compaction caused by water sloshing, has become a pressing technical problem in the current road paving field. How to design a compaction roller that can complete the weighting function in real time during paving and compaction, avoiding the need to stop work and add water as required by traditional methods, thus affecting work efficiency, and effectively suppressing the problems of center of gravity shift and uneven compaction caused by water sloshing inside the compaction roller during dynamic operations such as rolling and turning, thus ensuring the uniformity and stability of the paved road surface. Therefore, a fixed limiting ring 308 is fixedly connected to the inner wall of the compaction roller 301, and an annular groove 310 is opened on the outer wall of the fixed limiting ring 308.

[0019] A sliding roller 311 is slidably connected to the inner wall of the annular chute 310, and the sliding roller 311 is rotatably connected to both sides of the lifting float 309.

[0020] The lifting float 309 is slidably connected to the outer wall of the fixed limiting ring 308 on both sides. The lifting float 309 has a hollow structure inside. The inner wall of the lifting float 309 is provided with an internal spring, and the two ends of the internal spring are fixedly connected to the two sides of the inner wall of the lifting float 309.

[0021] Inside the compaction roller 301, water can be injected in real time through the fixed frame 6 and the hollow rotating sleeve 302 into the second water channel 304 opened on both sides of the compaction roller 301 by starting the water pump 5. The water flows into the bottom of the inner wall of the water storage chamber 305 through the second water channel 304, thereby realizing the function of adding weight to the compaction roller 301 in real time during the paving and rolling process, avoiding the traditional compaction roller 301 that can only be watered when it stops, which affects its working efficiency. When the compaction roller 301 rolls and turns, the water inside the compaction roller 301 is prone to sloshing, causing the center of gravity to shift. Under the centrifugal force of turning, the water tilts to one side, resulting in uneven compaction of the road surface by the compaction roller 301. To address this, the inner cavity of the compaction roller 301 is divided into multiple independent water chambers by a circular partition plate 306. Each water chamber is connected by a flow channel 307. The flow channel 307 has limited space, which effectively suppresses the inertial displacement of the water body when the water flows laterally quickly, ensuring the dynamic balance of water volume in each water chamber. Meanwhile, the water between each circular isolation plate 306 will float the lifting float plate 309 on top of it through buoyancy. The lifting float plate 309 floats synchronously with the rise and fall of the water level, covering the water surface. This effectively isolates the water from shaking when the compaction roller 301 rolls, shakes, and turns. The lifting float plate 309 slides in the annular groove 310 opened in the inner wall of the fixed limiting ring 308 through the sliding roller 311, completing the synchronous lifting and lowering displacement of the lifting float plate 309 with the liquid level, ensuring the uniformity and stability of the paved and compacted road surface.

[0022] Example 3: Please refer to Figure 1-8 Based on Embodiments 1 and 2, this invention provides a technical solution: In the field of road construction and maintenance, compaction rollers are key equipment used to compact road surface materials to improve road surface smoothness and strength. Traditionally, during operation, water is injected into the compaction roller to increase its weight and compaction effect. However, when the compaction roller rotates, the water inside will violently sway due to the rotational motion. This swaying not only makes it difficult for the lifting float (if present) to maintain a stable horizontal state, increasing the amplitude and frequency of water swaying below the float, thus affecting the stability of the roller's internal center of gravity, causing uneven pressure distribution on the road surface and affecting compaction quality, but also may damage the internal structure of the roller due to excessive swaying, shortening the equipment's service life.

[0023] During the water injection and weighting process, operators often struggle to accurately monitor the filling status of the water chambers inside the compaction drum in real time. Traditional methods frequently require periodic manual checks or rely on experience, making it impossible to adjust the water volume promptly based on actual conditions and achieve precise dynamic weight calibration. This can lead to either excessive or insufficient water injection, affecting compaction, and can also increase energy consumption and wear due to improper weighting, reducing construction efficiency and costs. Therefore, designing a compaction drum that effectively reduces the impact of internal water sloshing on the lifting float during rotation, maintaining the float's stable level and ensuring overall center of gravity stability, while simultaneously providing real-time intelligent feedback on the water chamber filling status, offers operators a basis for dynamic weight calibration, thereby improving compaction quality and construction efficiency. Therefore, how to solve the problem of instability and center of gravity shift of the lifting float caused by the internal water sloshing when the compaction roller rotates, and at the same time realize intelligent feedback of the water cavity filling state for dynamic counterweight calibration, has become a technical problem that urgently needs to be solved. Therefore, a balancing mechanism 4 is provided at the bottom of the lifting float 309. The balancing mechanism 4 includes a first telescopic rod 401, the top of which is fixedly connected to the bottom of the lifting float 309.

[0024] The bottom end of the first telescopic rod 401 is fixedly connected to a counterweight 402, and the bottom of the counterweight 402 is slidably connected to the outer wall of the lifting float 309.

[0025] The counterweight 402 is fixedly connected to both sides by connecting blocks 403, and the lifting float 309 is fixedly connected to the top by a distance sensor 404.

[0026] A second telescopic rod 405 is fixedly connected to the top of the distance sensor 404, and a rectangular slider 406 is fixedly connected to the top of the second telescopic rod 405. The inner wall of the rectangular slider 406 is slidably connected to the outer wall of the lifting float 309.

[0027] When the compaction roller 301 rotates, the first telescopic rod 401 at the bottom of the lifting float 309 stabilizes the horizontal position of the lifting float 309, reducing the amplitude and frequency of water sloshing below the lifting float 309. At the same time, the first telescopic rod 401 is positioned slightly to the left of the bottom of the lifting float 309, providing more counterweight to the left side of the lifting float 309. This ensures that even if the compaction roller 301 rolls and causes the lifting float 309 to sway, generating an eccentric force on the water inside, the first telescopic rod 401 can effectively counteract this force, thereby maintaining the overall center of gravity stability and keeping the lifting float 309 as balanced as possible. As more water is injected into the lifting float 309, the distance between the distance sensor 404 above the lifting float 309 and the top of the inner wall of the compaction roller 301 becomes closer. This allows the distance sensor 404 to automatically identify and detect the distance between the rectangular sliders 406 above, providing intelligent feedback on the real-time filling status of the water cavity and providing operators with a basis for dynamic counterweight calibration.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
