Description

Technical Field

[0001] This invention relates to the field of highway bridge technology, and in particular to a backfill compaction device for culverts used in highway bridges. Background Technology

[0002] Highway bridge engineering refers to all work related to the planning, design, construction, maintenance, and repair of structures that cross waterways, valleys, and all traffic channels. When constructing a highway bridge, the ground needs to be excavated, and the excavated ground needs to be filled back and compacted.

[0003] When using existing backfilling and compaction equipment, water is sprayed to avoid dust. However, this spraying turns the soil into mud, which is not conducive to compaction. At the same time, the existing compaction rollers lack a cleaning structure. During the compaction process, some soil adheres to the surface of the compaction rollers, causing changes in the shape of the rollers and resulting in uneven compacted ground, which is not conducive to the use of the compaction equipment. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as: watering can cause the soil on the ground to turn into mud, which is not conducive to compaction; lack of cleaning structure; and during the compaction process, some soil will adhere to the surface of the compaction roller, causing the shape of the compaction roller to change, resulting in an uneven compacted ground, which is not conducive to the use of the compaction equipment. Therefore, this invention proposes a culvert backfill compaction device for highway bridges.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A backfill compaction device for culverts used in highway bridges includes a fixed plate connected to a drive vehicle. A fixed shaft is rotatably connected between the fixed plates. A rotating disk is located at the end of the fixed shaft furthest from the corresponding fixed plate. A compaction roller is fixedly connected between the rotating disks. A fixed frame is rotatably connected to the drive vehicle. A damping structure is provided at the connection between the drive vehicle and the fixed frame. A connecting plate is fixedly connected at the end of the fixed frame furthest from the drive vehicle. The width of the connecting plate corresponds to the compaction roller. An atomizing nozzle is fixedly connected to the bottom of the connecting plate. The atomizing nozzle is fixedly connected to a water tank via a connecting pipe and faces the ground. The connecting plate is located in front of the rotating disk. A dust-collecting structure is provided on the fixed plate.

[0007] Preferably, the dust collection structure includes a bevel gear one fixedly sleeved on a fixed shaft, a fixed frame fixedly connected to the end of each fixed plate near the compaction roller, a connecting shaft rotatably connected to the upper inner wall of the fixed frame, the connecting shaft extending through the upper inner wall of the fixed frame to the outside of the fixed frame, a bevel gear two corresponding to the bevel gear one fixedly connected to the top of the connecting shaft, and the bevel gear two meshing with the bevel gear one, a fan blade fixedly connected to the side wall of the part of the connecting shaft inside the fixed frame, a connecting net slidably connected between the inner walls of the fixed frame, multiple connecting blocks arranged below the connecting net, each connecting block fixedly connected to the inner side wall of the fixed frame, a vertically arranged connecting spring fixedly connected to the top of each connecting block, and the end of the connecting spring away from the corresponding connecting block fixedly connected to the top of the connecting net.

[0008] Preferably, the bottom end of the connecting shaft is located close to the connecting mesh, and an extrusion plate is fixedly connected to the bottom end of the connecting shaft. An extrusion block corresponding to the extrusion plate is fixedly connected to the top end of the connecting mesh. Both the extrusion plate and the extrusion block are made of elastic material, and the connecting mesh is an electrostatic adsorption mesh.

[0009] Preferably, the fixed shaft and the corresponding rotating disk are slidably connected. A fixed block is fixedly connected to the side wall of the fixed shaft. A fixed groove corresponding to the fixed block is opened on the side wall of the rotating disk. The fixed groove is circular. A buffer spring is sleeved on the side wall of the fixed block. Multiple fixed sleeves are fixedly connected to the side wall of the buffer spring. The end of each fixed sleeve away from the buffer spring is fixedly connected to the inner side wall of the fixed groove. A damping plate is fixedly installed on each fixed sleeve.

[0010] Preferably, each of the fixed sleeves is fitted with a fixed sleeve on its outer side, and the two ends of the fixed sleeve are fixedly connected to the buffer spring and the inner wall of the fixed groove, respectively. The fixed sleeve is a telescopic structure and is made of hard rubber.

[0011] Preferably, the drive vehicle is equipped with a control device corresponding to the mounting bracket and the atomizing nozzle.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-4A backfill compaction device for culverts used in highway bridges includes a fixed plate 1 connected to a drive vehicle. A fixed shaft 2 is rotatably connected between the fixed plates 1. A rotating disc 3 is mounted on the end of the fixed shaft 2 furthest from the corresponding fixed plate 1. A compaction roller 4 is fixedly connected between the rotating discs 3. A fixed frame 23 is rotatably connected to the drive vehicle. A damping structure is provided at the connection between the drive vehicle and the fixed frame 23. A connecting plate 20 is fixedly connected to the end of the fixed frame 23 furthest from the drive vehicle. The width of the connecting plate 20 corresponds to the width of the compaction roller 4. An atomizing nozzle 21 is fixedly connected to the bottom end of the connecting plate 20. The atomizing nozzle 21 is fixedly connected to a water tank via a connecting pipe, and the atomizing nozzle 21 is oriented towards the ground. The receiving plate 20 is located in front of the rotating disk 3. The fixed plate 1 is equipped with a dust collection structure. The drive vehicle pushes the fixed plate 1 to move, so that the compaction roller 4 flattens the ground. At the same time, before the compaction roller 4 compacts the ground, the water in the water tank is sprayed out through the connecting pipe and the atomizing nozzle 21. The water mist is sprayed into the air and on the ground, thereby reducing dust. Moreover, less water falls on the ground, preventing the soil from turning into mud due to excessive water. When the compaction roller 4 compacts, water splashes out. In addition, the water mist remaining in the air can combine with the dust raised, thereby settling down and preventing excessive dust from escaping into the air. Finally, the remaining dust is removed by the dust collection structure, which helps to avoid air pollution.

[0022] The dust collection structure includes a bevel gear 10 fixedly mounted on a fixed shaft 2. Each fixed plate 1 has a fixed frame 12 fixedly connected to one end near the compaction roller 4. A connecting shaft 16 is rotatably connected to the upper inner wall of the fixed frame 12, extending through the upper inner wall of the fixed frame 12 to the outside of the fixed frame 12. A bevel gear 11 corresponding to the bevel gear 10 is fixedly connected to the top of the connecting shaft 16, and the bevel gear 11 meshes with the bevel gear 10. A fan blade 17 is fixedly connected to the side wall of the inner part of the fixed frame 12. A connecting mesh 13 is slidably connected between the inner walls of the fixed frame 12. Multiple connecting blocks 14 are arranged below the connecting mesh 13. All connecting blocks 14 are fixedly connected to the inner side wall of the fixed frame 12. Each connecting block 14 has a vertically set connecting spring 15 fixedly connected to its top. The end of the connecting spring 15 away from the corresponding connecting block 14 is fixedly connected to the top of the connecting net 13. When the compaction roller 4 compacts the ground, it will rotate, which will cause the rotating disk 3 and the fixed shaft 2 to rotate, driving the bevel gear 10 to rotate, and causing the bevel gear 11 meshing with it to rotate together. When the bevel gear 11 rotates, it will cause the connecting shaft 16 and the fan blade 17 to rotate. The fan blade 17 rotates to generate wind, which will suck the remaining dust into the fixed frame 12. The sucked-in dust will be absorbed by the connecting net 13, and the dust will gather together to form small clods.

[0023] The bottom end of the connecting shaft 16 is located close to the connecting mesh 13, and a pressing plate 18 is fixedly connected to the bottom end of the connecting shaft 16. A pressing block 19 corresponding to the pressing plate 18 is fixedly connected to the top end of the connecting mesh 13. Both the pressing plate 18 and the pressing block 19 are made of elastic material. The connecting mesh 13 is an electrostatic adsorption mesh to attract dust. When the connecting shaft 16 rotates, the pressing plate 18 will rotate with it. During the rotation of the pressing plate 18, it will press against the pressing block 19, causing the connecting mesh 13 to move downward and the connecting spring 15 to contract. As the pressing plate 18 rotates, the pressing plate 18 separates from the pressing block 19. Under the action of the elastic force of the connecting spring 15, the connecting mesh 13 moves upward, causing the connecting mesh 13 to vibrate up and down. Since the dust is relatively light, it will not be shaken off. However, the small clods of dust are relatively heavy and will be shaken off to the ground, preventing them from clogging the connecting mesh 13.

[0024] The fixed shaft 2 and the corresponding rotating disk 3 are slidably connected. A fixed block 5 is fixedly connected to the side wall of the fixed shaft 2. A fixed groove 6 corresponding to the fixed block 5 is opened on the side wall of the rotating disk 3. The fixed groove 6 is circular. A buffer spring 7 is sleeved on the side wall of the fixed block 5. Multiple fixed sleeves 8 are fixedly connected to the side wall of the buffer spring 7. The end of each fixed sleeve 8 away from the buffer spring 7 is fixedly connected to the inner side wall of the fixed groove 6. A vibration damping plate is fixedly installed on each fixed sleeve 8. When the compaction roller 4 moves on the ground, it will vibrate when it moves to an uneven position on the ground. The vibration damping plate and the buffer spring 7 work together to buffer the vibration, thereby reducing the vibration of the entire device and facilitating the operation of the compaction roller 4.

[0025] Each fixed sleeve 8 is fitted with a fixed sleeve 9 on its outer side. The two ends of the fixed sleeve 9 are fixedly connected to the buffer spring 7 and the inner wall of the fixed groove 6, respectively. The fixed sleeve 9 is a telescopic structure and is made of hard rubber to ensure that the rotating disk 3 and the fixed shaft 2 are always fixed together.

[0026] The drive vehicle is equipped with a control device corresponding to the fixed frame 23 and the atomizing nozzle 21. The angle of the fixed frame 23 can be adjusted by the control device so that the scraper 22 is in contact with the compaction roller 4. At the same time, the atomizing nozzle 21 can be started and stopped. The scraper 22 is fixedly connected to one end of the connecting plate 20 near the compaction roller 4. The scraper 22 is covered with a protective layer. The scraper 22 scrapes off the soil adhering to the surface of the compaction roller 4. The scraper 22 is in contact with the compaction roller 4. The tops of the scraper 22 and the connecting plate 20 are inclined. Under the action of gravity, the scraped soil slides down the tops of the scraper 22 and the connecting plate 20 to the front of the compaction roller 4 and is compacted by the compaction roller 4.

[0027] In this invention, when the device is in use, the angle of the fixed frame 23 is first adjusted by the control device so that the scraper 22 is in contact with the compaction roller 4. Then, the fixed plate 1 is moved by the drive vehicle, so that the compaction roller 4 moves to flatten the ground. At the same time, before the compaction roller 4 compacts the ground, the atomizing nozzle 21 is activated. Water in the water tank is sprayed out through the connecting pipe from the atomizing nozzle 21. The water mist is sprayed into the air and onto the ground, thereby reducing dust and minimizing the amount of water falling onto the ground, preventing the soil from turning into mud due to excessive water. During the compaction of the compaction roller 4, splashing occurs. In addition to the initial compaction, residual water mist in the air can combine with the raised dust, causing it to settle and preventing excessive dust from escaping into the air. Finally, the compaction roller 4 rotates while compacting the ground, causing the rotating disk 3 and the fixed shaft 2 to rotate, which in turn drives the bevel gear 10 to rotate, causing the meshing bevel gear 11 to rotate as well. The rotation of the bevel gear 11 causes the connecting shaft 16 and the fan blade 17 to rotate. The rotation of the fan blade 17 generates wind, which draws the remaining dust into the fixed frame 12. The drawn-in dust is then absorbed by the connecting mesh 13. This helps prevent air pollution, as dust accumulates to form small clods. Furthermore, when the connecting shaft 16 rotates, the pressing plate 18 rotates accordingly. During this rotation, the pressing plate 18 presses against the pressing block 19, causing the connecting mesh 13 to move downwards and the connecting spring 15 to contract. As the pressing plate 18 rotates, it separates from the pressing block 19. Under the elastic force of the connecting spring 15, the connecting mesh 13 moves upwards, causing it to vibrate up and down. Because dust is relatively light, it will not be shaken off, while the small clods formed by the dust will remain intact. Because it is relatively heavy, it will be shaken off to the ground to prevent it from clogging the connecting net 13. At the same time, when the compaction roller 4 moves on the ground, it will vibrate when it moves to an uneven position on the ground. The damping plate and the buffer spring 7 work together to buffer the vibration, thereby reducing the vibration of the entire device and facilitating the operation of the compaction roller 4. In addition, the scraper plate 22 scrapes off the soil adhering to the surface of the compaction roller 4. Under the action of gravity, the scraped soil slides down along the top of the scraper plate 22 and the connecting plate 20 to the front of the compaction roller 4 and is compacted by the compaction roller 4.

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.
