Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a municipal road paving leveling and compaction device. Background Technology

[0002] Municipal roads refer to roads that connect various areas of a city, are used for urban transportation and pedestrians, facilitate residents' lives, work and cultural and recreational activities, and connect with roads outside the city to bear external traffic. In the paving of sidewalk bricks in municipal engineering, due to environmental limitations, automatic brick paving machines cannot be used in some sections, so manual paving is required.

[0003] However, after the bricks are laid, they cannot be compacted, resulting in an unstable connection between the bricks and the ground. This causes the bricks to wobble when stepped on, especially in rainy weather when they are splashed with sewage. Furthermore, when leveling the bricks, workers usually use rubber mallets to compact them, which can only level one brick at a time, making it inefficient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the low efficiency of using rubber hammers to compact bricks, and to propose a municipal road paving leveling and compaction device.

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

[0006] Design a municipal road paving leveling and compaction device, including a connector, a rotating shaft rotatably mounted on the connector, stroke wheels fixed to both ends of the outer wall of the rotating shaft, a rotating body fixed to the outer wall of the rotating shaft, a plurality of radial grooves opened on the rotating body, a slider slidingly fitted in the groove, an arc-shaped pressure block fixed to the slider, and an impact structure provided in the groove to apply pressure to the pressure block when it is at its lowest point.

[0007] Preferably, the slide groove is provided with a compression spring to apply a centripetal elastic force to the slider.

[0008] Preferably, the impact structure includes a counterweight block that is slidably fitted in a groove, a wedge-shaped insert fixed to the outer wall of the counterweight block, a long shaft rotatably fitted on the stroke wheel, and a wedge-shaped hook fixed to the outer wall of the long shaft, the hook matching the insert block.

[0009] Preferably, a driven gear is fixedly connected to the outer wall of the long shaft, a tension spring is fixedly connected to the top of the slide groove, and a toothed block is fixedly connected to the end of the tension spring, the toothed block matching the driven gear.

[0010] Preferably, the weight of the toothed block is greater than the elastic force of the tension spring.

[0011] The present invention proposes a municipal road paving leveling and compaction device, which has the following advantages: the municipal road paving leveling and compaction device provided by this device can perform the work of flattening the paving bricks, and can also choose whether to perform the compaction operation as needed, so that construction workers can flexibly choose the road paving method according to the road surface conditions.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4A municipal road paving leveling and compaction device includes a connector 1, a rotating shaft 2 rotatably mounted on the connector 1, stroke wheels 3 fixedly connected to both ends of the outer wall of the rotating shaft 2, a rotating body 4 fixedly connected to the outer wall of the rotating shaft 2, a plurality of radial grooves 5 opened on the rotating body 4, a slider 7 slidably fitted in the grooves 5, an arc-shaped pressure block 6 fixedly connected to the slider 7, and an impact structure provided in the grooves 5 to apply pressure to the pressure block 6 when it is at its lowest point.

[0021] During road paving, this device is connected to the traction device via the front connector 1. The traction device moves this device on the paved sidewalk tiles. During the movement, the cylindrical pressure roller formed by the rotating body 4 and the arc-shaped pressure block 6 will level the tiles on the ground. As the pressure roller rotates, when the pressure block 6 is at the bottom and in contact with the tiles, the impact structure will apply a vertical downward impact force to the pressure block 6, so that the impact force is applied to the tiles through the pressure block, thereby compacting the tiles.

[0022] like Figure 4 and Figure 5 A compression spring 16 is provided in the slide 5 to apply a centripetal elastic force to the slider 7. The compression spring 16 applies pressure to the slider 7 so that the pressure block 6 will not undergo centrifugal motion due to centrifugal force during rotation.

[0023] like Figures 4-6 The impact structure includes a counterweight 8, which is slidably fitted in a groove 5. A wedge-shaped insert 9 is fixed to the outer wall of the counterweight 8. A long shaft 10 is rotatably fitted on the stroke wheel 3. A wedge-shaped hook 11 is fixed to the outer wall of the long shaft 10. The hook 11 matches the insert 9. A driven gear 12 is fixed to the outer wall of the long shaft 10. An installation groove 13 is opened at the top of the groove 5. A tension spring 15 is fixed to the top of the installation groove 13. A toothed block 14 is fixed to the end of the tension spring 15. The toothed block 14 matches the driven gear 12. The weight of the toothed block 14 is greater than the elastic force of the tension spring 15.

[0024] During the rotation of the pressure roller, the tension force generated by the tension spring 15 on the toothed block 14 keeps the toothed block 14 stable and prevents centrifugal motion due to centrifugal force during rotation. When the pressure block 6 rotates to the lowest point, it moves downward under the gravity of the toothed block 14 itself. The downward movement of the toothed block 14 drives the driven gear 12 to deflect. After the driven gear 12 deflects, it drives the hooks 11 to deflect to both sides through the long shaft 10, thereby increasing the distance between the two hooks 11. After the distance between the two hooks increases, the wedge-shaped insert 9 will fall off between the two hooks 11 under the action of gravity. The counterweight 8 slides down in the slide groove 5 under the action of gravity. The gravitational potential energy of the counterweight 8 is converted into kinetic energy and applied to the slider 7. The impact force on the slider 7 will be applied to the floor tile below the pressure roller through the pressure block 6 to compact the floor tile.

[0025] like Figures 1-3The long shaft 10 is slidably fitted with the travel wheel 3. A stud 19 is rotatably mounted on the outer end face of the travel wheel 3. A ring-shaped brake block 18 is threaded onto the stud 19. A through hole is opened on the brake block 18. The long shaft 10 passes through the through hole and passes through the brake block 18. A friction block 17 is fixedly connected to the end of the long shaft 10. When the drive stud 19 rotates, the stud 19 will drive the brake block 18 to move axially. When the brake block 18 moves axially to abut against the friction block 17, the long shaft 10 will be locked and cannot rotate. At this time, the impact structure will be locked, so that the device can only perform flattening work.

[0026] Compared to traditional technologies, the municipal road paving leveling and compaction device provided by this equipment can not only flatten the paving bricks, but also choose whether to perform compaction operations as needed, allowing construction workers to flexibly choose the road paving method according to the road surface conditions.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
