Description

Technical Field

[0001] This utility model relates to the field of road construction, specifically to a road surface leveling auxiliary device for road construction. Background Technology

[0002] Road construction involves excavating the road foundation according to design requirements, achieving the specified depth and slope. During filling, suitable fill materials, such as crushed stone, pebbles, gravel, and coarse sand, must be selected and compacted in layers to ensure the stability and bearing capacity of the foundation. Based on the soil and hydrological conditions of the site, appropriate treatment measures, such as drainage, replacement, and reinforcement, are taken to improve the stability of the roadbed. Compaction equipment, such as road rollers, is used to compact the roadbed, ensuring that the density meets design requirements and preventing later settlement problems. During pavement construction, a smooth surface must be ensured. To facilitate this smoothing process, auxiliary operations are needed; therefore, a road surface smoothing auxiliary device for road construction is required.

[0003] The existing announcement number CN221398576U provides a road surface leveling device for road construction, including a stabilizing block. The top of the stabilizing block has an adjustment groove, and a stabilizing slider is slidably connected inside the adjustment groove. One end of the stabilizing slider has a motor slot, and one end of the motor slot is fixedly connected to a first motor. The output end of the first motor is fixedly connected to a rotating gear. The top of the stabilizing block is fixedly connected to a stabilizing rack. The rotating gear meshes with the stabilizing rack, causing the stabilizing slider to move. During the movement of the stabilizing slider, a flipping rod is flipped, which in turn moves the adjustment slider. The adjustment slider, in turn, causes a compaction block to press down on the ground, further improving the road surface leveling effect. However, this device cannot assist in leveling road surfaces of different widths, nor can it be used for leveling different road surfaces simultaneously. Furthermore, the entire device is not portable for carrying and use. Therefore, there is an urgent need for a road surface leveling auxiliary device for road construction. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a road surface leveling auxiliary device for road construction, so as to solve the problems that existing road surface leveling auxiliary devices for road construction cannot perform leveling auxiliary operations on roads of different widths, cannot perform leveling operations on different road surfaces during operation, and cannot be carried and used in a portable manner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road surface leveling auxiliary device for road construction, comprising a load-bearing frame, rollers installed at the lower end of the load-bearing frame, a baffle installed on the inner wall of the load-bearing frame, a leveling plate placed on the upper end of the baffle, a placement groove opened on the upper end of the leveling plate, a counterweight installed inside the placement groove, slots opened at both the front and rear ends of the leveling plate, a buckle installed at the upper end of the slot, a connecting rope installed at one end of the leveling plate, a pull handle installed at one end of the connecting rope, a stabilizing platform installed on the upper end of the load-bearing frame, a threaded rod installed on the upper end of the stabilizing platform, a telescopic rod installed in the middle of the stabilizing platform, a movable groove opened on the upper end of the load-bearing frame, a support frame installed at one end of the movable groove, a limit plate installed at one end of the support frame, and a roller installed at one end of the limit plate.

[0006] Preferably, the counterweight is engaged with the flat plate via a placement groove, and the flat plate is engaged with a buckle via a slot.

[0007] Preferably, the counterweight is embedded in the connecting rope, and the connecting rope is sleeved with the roller.

[0008] Preferably, the stabilizing platform is threadedly connected to the load-bearing frame via a threaded rod, and the stabilizing platform can be adjusted in front and behind via a telescopic rod.

[0009] Preferably, the support frame is engaged with the load-bearing frame via a movable slot, and the load-bearing frame is symmetrically arranged with respect to the central axis of the telescopic rod.

[0010] Preferably, the roller is movably connected to the limiting plate, and the roller is symmetrically arranged with respect to the central axis of the telescopic rod.

[0022] Please see Figure 1-4A road surface leveling auxiliary device for road construction includes a load-bearing frame 1, with rollers 2 installed at the lower end of the load-bearing frame 1. A baffle 3 is installed on the inner wall of the load-bearing frame 1, and a leveling plate 4 is placed on the upper end of the baffle 3. A placement groove 5 is opened at the upper end of the leveling plate 4, and a counterweight 6 is installed inside the placement groove 5. The counterweight 6 is engaged with the leveling plate 4 through the placement groove 5, and the leveling plate 4 is engaged with a buckle 8 through a slot 7. The counterweight 6 installed in the device can adjust the weight of the leveling plate 4, which can adapt to the leveling operation for different road surfaces. Slots 7 are opened at both the front and rear ends of the leveling plate 4, and buckles 8 are installed at the upper end of the slots 7. A connecting rope 9 is installed at one end of the leveling plate 4, and a pull handle 10 is installed at one end of the connecting rope 9. The counterweight 6 and the connecting rope 9 are embedded and connected. Rope 9 is sleeved and connected to roller 17. The connecting rope 9 installed in the device can restrict the position of the flat plate 4, making it easier to use the flat plate 4. A stabilizing platform 11 is installed on the upper end of the load-bearing frame 1. A threaded rod 12 is installed on the upper end of the stabilizing platform 11. A telescopic rod 13 is installed in the middle of the stabilizing platform 11. The stabilizing platform 11 is threadedly connected to the load-bearing frame 1 through the threaded rod 12. The stabilizing platform 11 can be adjusted back and forth through the telescopic rod 13. The load-bearing frames 1 installed at both ends of the device can be adjusted in distance through the telescopic rod 13, which can adapt to different road widths for operation. A movable groove 14 is opened on the upper end of the load-bearing frame 1. A support frame 15 is installed at one end of the movable groove 14. A limit plate 16 is installed at one end of the support frame 15. A roller 17 is installed at one end of the limit plate 16.

[0023] Working principle: During use, the width of the two sets of load-bearing frames 1 is adjusted according to the required road width for leveling. The load-bearing frames 1 are fixed to the stabilizing platform 11. After fixing, the distance between the two sets of load-bearing frames 1 is adjusted using the telescopic rod 13 installed inside one end of the stabilizing platform 11 to adapt to the required road width. After adjustment, a leveling plate 4 matching the road width is replaced. Once the leveling plate 4 is installed, it can be connected using the connecting rope 9. After connection, the connecting rope 9 is wound around the roller 17, and the connecting rope 9 is pulled by the pull handle 10. The counterweight 6 is installed inside the placement groove 5 opened on the flat plate 4. After placement, the counterweight 6 is fixed by the buckle 8. The flat plate 4 is tilted and supported by the installed baffle 3, so that one end of the flat plate 4 with the counterweight 6 is in contact with the road surface. After contact, the flat plate 4 can be fixed by pulling the lever 10. After fixing, it can be moved by the roller 2 installed at the lower end of the load-bearing frame 1 to level the road surface. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
