Description

Technical Field

[0001] This utility model relates to the field of road roller technology, and in particular to a road roller for building foundation construction. Background Technology

[0002] Building foundation construction refers to a series of engineering activities that treat and reinforce the foundation of a building site before the construction of a building. The purpose is to improve the bearing capacity of the foundation, ensure its stability, reduce foundation settlement and uneven settlement, so as to meet the building's requirements for the strength, deformation and stability of the foundation. Road rollers are often used during foundation construction.

[0003] Existing technologies, such as the utility model with publication number CN215857058U, disclose a road roller for building foundation construction, which relates to the field of construction machinery technology. It includes a protective shell, two fixed plates fixedly installed on the outside of the protective shell, and a dryer fixedly fitted on the top of the protective shell. A connecting shaft is movably connected between the two fixed plates, and a roller is fixedly fitted on the outside of the connecting shaft. A fixed box is fixedly fitted on the front of the protective shell.

[0004] Currently, most existing road rollers have an integrated roller structure, which is large in size and heavy in weight. The road rollers need to overcome a lot of resistance when running, resulting in energy waste. In addition, traditional rollers tend to transmit a large impact force to the road surface during operation, causing problems such as local depressions and cracks, which affect the road surface quality and service life. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing road rollers, which are mostly integrated structures with large size and weight. The road rollers need to overcome great resistance during operation, resulting in energy waste. In addition, traditional rollers tend to transmit large impact forces to the road surface during operation, causing problems such as local depressions and cracks, which affect the quality and service life of the road surface. Therefore, a road roller for building foundation construction is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a road roller for building foundation construction, comprising a carrier plate, a cylinder fixedly connected to the upper surface of the carrier plate, a through hole opened on the surface of the carrier plate, the driving end of the cylinder passing through the through hole, an mounting block fixedly connected to the upper surface of the carrier plate, an mounting frame fixedly connected to the driving end of the cylinder, a protrusion fixedly connected to the lower surface of the mounting frame, a support rod fixedly connected to the surface of the protrusion, a bearing mounted on the support rod, a pressure roller mounted on the bearing, the pressure roller having a hollow structure, a counterweight roller placed on the inner wall of the pressure roller, the setting of the counterweight roller increasing the weight of the pressure roller, enabling the pressure roller to generate greater pressure on the foundation during rolling, a guide roller contacting the surface of the counterweight roller and rotating with the rotation of the counterweight roller, always maintaining stable support and guidance for the counterweight roller, ensuring the stability of the center of gravity of the counterweight roller. This design allows for a more uniform pressure distribution during the rolling process, avoiding inconsistent compaction results caused by the offset of the counterweight roller's center of gravity. This improves the uniformity and stability of the compaction effect. At the same time, the hollow compaction roller is lighter than traditional rollers, reducing the resistance that the engine needs to overcome when the roller is in motion and operation. This reduces fuel or electricity consumption, achieving energy conservation and environmental protection. Long-term use can significantly reduce construction costs.

[0007] Preferably, a positioning block is fixedly connected to the inner wall of the support rod, and a guide roller is rotatably connected to the surface of the positioning block. The hollow pressure roller has a certain elasticity, which can buffer the impact force on the ground during the rolling process, reduce cracks and damage to the road surface caused by excessive local pressure, and improve the road surface smoothness and compaction quality. It is especially suitable for roads with high requirements for smoothness.

[0008] Preferably, the number of guide rollers is four, and the four guide rollers are distributed in pairs at both ends of the support rod, with the two pairs of guide rollers in contact with the surface of the counterweight roller.

[0009] Preferably, there are two cylinders, which are mirror images of each other. The lifting and lowering of the pressure roller is controlled by the two synchronously working cylinders. This allows for precise adjustment of the distance between the pressure roller and the ground according to different construction needs and foundation conditions. Whether it is bringing the pressure roller closer to the ground before starting road rolling operations or lifting the pressure roller for movement after the operation is completed, this can be done quickly and stably, improving the flexibility and efficiency of construction and adapting to a variety of complex construction scenarios.

[0010] Preferably, the number of mounting blocks is three, and the three mounting blocks are arranged at equal intervals. The surface of the mounting blocks is provided with mounting holes to facilitate the installation of the road roller on the drive equipment.

[0011] Preferably, a positioning rod is fixedly connected to one side of the carrier plate, and a sliding sleeve is fixedly connected to the surface of the mounting frame. The positioning rod slides against the inner wall of the sliding sleeve, thereby limiting the movement trajectory of the mounting frame.

[0012] Preferably, a stop is fixedly connected to the lower end of the positioning rod to prevent the sliding sleeve from disengaging from the positioning rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, the addition of a counterweight roller increases the weight of the pressure roller, enabling it to exert greater pressure on the foundation during rolling. The guide roller contacts the surface of the counterweight roller and rotates with it, maintaining stable support and guidance. This ensures the stability of the counterweight roller's center of gravity, resulting in a more uniform pressure distribution during rolling. This avoids inconsistent compaction effects caused by the counterweight roller's center of gravity shifting, improving the uniformity and stability of the compaction effect. Furthermore, the hollow pressure roller, unlike traditional rollers, is lighter, reducing the resistance the engine needs to overcome during roller operation and thus lowering fuel or electricity consumption, achieving energy conservation and environmental protection. Long-term use can significantly reduce construction costs.

[0015] In this invention, the hollow roller has a certain degree of elasticity, which can buffer the impact on the ground during the rolling process, reduce cracks and damage to the road surface caused by excessive local pressure, and improve the road surface smoothness and compaction quality. It is especially suitable for roads with high requirements for smoothness.

[0016] In this invention, the lifting and lowering of the pressure roller is controlled by two synchronously working cylinders. The distance between the pressure roller and the ground can be precisely adjusted according to different construction needs and foundation conditions. Whether it is to bring the pressure roller close to the ground before starting road rolling operations or to lift the pressure roller for movement after the operation is completed, it can be done quickly and stably, improving the flexibility and efficiency of construction and adapting to a variety of complex construction scenarios.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a road roller for building foundation construction, including a carrier plate 1, a cylinder 2 fixedly connected to the upper surface of the carrier plate 1, a through hole 15 opened on the surface of the carrier plate 1, the driving end of the cylinder 2 passing through the through hole 15, an mounting block 3 fixedly connected to the upper surface of the carrier plate 1, an mounting frame 4 fixedly connected to the driving end of the cylinder 2, a protrusion 6 fixedly connected to the lower surface of the mounting frame 4, a support rod 11 fixedly connected to the surface of the protrusion 6, a bearing 10 mounted on the support rod 11, a pressure roller 5 mounted on the bearing 10, the pressure roller 5 having a hollow structure, a counterweight roller 14 placed on the inner wall of the pressure roller 5, the counterweight roller 14 increasing the weight of the pressure roller 5, so that the pressure roller 5 rolls... During operation, it can generate greater pressure on the foundation. The guide roller 13 contacts the surface of the counterweight roller 14 and rotates with the counterweight roller 14, always maintaining stable support and guidance for the counterweight roller 14. This ensures the stability of the center of gravity of the counterweight roller 14, making the pressure distribution of the pressure roller 5 more uniform during rolling. It avoids inconsistent road compaction effects caused by the offset of the center of gravity of the counterweight roller 14, and improves the uniformity and stability of the road compaction effect. At the same time, the hollow pressure roller 5 is lighter than traditional rollers. When the road roller is traveling and operating, the resistance that the engine needs to overcome is reduced, thereby reducing fuel consumption or power consumption, achieving energy saving and environmental protection. Long-term use can significantly reduce construction costs.

[0025] In this embodiment: a positioning block 12 is fixedly connected to the inner wall of the support rod 11, and a guide roller 13 is rotatably connected to the surface of the positioning block 12. The hollow pressure roller 5 has a certain elasticity, which can buffer the impact force on the ground during the rolling process, reduce the cracks and damage to the road surface caused by excessive local pressure, and improve the road surface smoothness and compaction quality. It is especially suitable for roads with high requirements for smoothness.

[0026] Specifically, there are four guide rollers 13, which are distributed in pairs at both ends of the support rod 11, and the two pairs of guide rollers 13 are in contact with the surface of the counterweight roller 14.

[0027] In this embodiment, there are two cylinders 2, which are mirror images of each other. The lifting and lowering of the pressure roller 5 is controlled by the two synchronously working cylinders 2. The distance between the pressure roller 5 and the ground can be precisely adjusted according to different construction needs and foundation conditions. Whether the pressure roller 5 is brought close to the ground before the start of road rolling operation or the pressure roller 5 is lifted for movement after the operation is completed, it can be done quickly and stably, which improves the flexibility and efficiency of construction and adapts to a variety of complex construction scenarios.

[0028] Specifically, there are three mounting blocks 3, which are arranged at equal intervals. The surface of the mounting blocks 3 is provided with mounting holes to facilitate the installation of the road roller on the drive equipment.

[0029] Specifically, a positioning rod 7 is fixedly connected to one side of the carrier plate 1, and a sliding sleeve 8 is fixedly connected to the surface of the mounting bracket 4. The positioning rod 7 slides against the inner wall of the sliding sleeve 8, and the movement trajectory of the mounting bracket 4 is limited by the positioning rod 7 and the sliding sleeve 8.

[0030] Specifically, a stop 9 is fixedly connected to the lower end of the positioning rod 7 to prevent the sliding sleeve 8 from disengaging from the positioning position.

[0031] Working principle: Before road rolling, the mounting block 3 is installed on the drive equipment using bolts and other components. When the height of the pressure roller 5 needs to be adjusted, cylinder 2 is activated. Both cylinders 2 work synchronously, with their drive ends extending downward through the through hole 15, pushing the mounting frame 4 downward. Since the mounting frame 4 is slidably connected to the positioning rod 7 fixedly connected to one side of the carrier plate 1 via the sliding sleeve 8, the stop block 9 at the lower end of the positioning rod 7 prevents the sliding sleeve 8 from falling off the positioning rod 7, ensuring that the mounting frame 4 can move stably downward along the positioning rod 7 during descent. As the mounting frame 4 descends, the connected components such as the protrusion 6, support rod 11, and pressure roller 5 also descend, bringing the pressure roller 5 close to the ground, ready for road rolling.

[0032] During road rolling operations, the pressure roller 5 rolls on the ground, and the counterweight roller 14 increases the weight of the pressure roller 5, enabling the pressure roller 5 to exert greater pressure on the foundation during rolling, thereby more effectively compacting the foundation. The guide roller 13 is in contact with the surface of the counterweight roller 14. During the rotation of the pressure roller 5, the guide roller 13 rotates along with the counterweight roller 14, always maintaining stable support and guidance for the counterweight roller 14, ensuring the stability of the center of gravity of the counterweight roller 14, and improving the uniformity and stability of the road rolling effect.
