Description

Technical Field

[0001] This invention relates to the field of pedestrian road renovation and construction technology in old urban areas, specifically a device for renovating granite curb stones in old urban areas. Background Technology

[0002] During the renovation of pedestrian walkways in old urban areas, it is necessary to remove old granite curbs to repair the sidewalks, and then repave the curbs. Granite curbs have a long production cycle and are expensive; purchasing new curbs does not align with cost-saving and energy-efficient principles. Using old curbs can save significant material costs. However, the removed old curbs, due to prolonged use, have stains, scratches, and paint residue from parking space planning, as well as residual old mortar, which negatively impacts the city's aesthetics. Therefore, refurbishing the old curbs becomes a key focus of the entire construction process. To address this, a granite curb refurbishment device for old urban areas is proposed. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned problems, thereby providing a device for renovating granite curbs in old urban areas.

[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:

[0005] A device for renovating granite curbs in old urban areas includes a frame with several rollers arranged parallel above the frame. Both ends of the rollers are rotatably connected to the frame. A third drive motor for driving the rollers is also installed on the frame. A horizontal grinding mechanism is installed on the frame between two adjacent rollers, and a vertical grinding mechanism is installed on the frame between two other adjacent rollers. The curb moves from one side of the frame to the other above the rollers, passing through the horizontal grinding mechanism and the vertical grinding mechanism in sequence. The vertical grinding mechanism can grind both sides of the curb simultaneously.

[0006] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0007] This invention enables the renovation of old curb stones. The curb stone is placed above the roller, and the third drive motor is started. The curb stone moves from one side of the frame to the other above the roller, passing through the horizontal grinding mechanism and the vertical grinding mechanism in sequence. The horizontal grinding mechanism grinds the top surface of the curb stone, while the vertical grinding mechanism grinds both sides of the curb stone simultaneously. This quickly and effectively processes and updates the visible surface of the granite curb stone, ensuring construction quality, improving the appearance, and saving a significant amount of construction costs.

[0030] Before use, adjust the positions of the horizontal roller brush 55 and the vertical roller brush 66 so that when the curbstone passes by, the horizontal roller brush 55 and the vertical roller brush 66 can make soft contact with the top surface and both sides of the curbstone, respectively. When in use, place the old curbstone on top of the idler roller 2, start the third drive motor 3, the first motor 53 and the second motor 65. The third drive motor 3 drives multiple idler rollers 2 to rotate through the chain 4. The curbstone moves from one side of the frame 1 to the other side above the idler roller 2, passing through the horizontal grinding mechanism 5 and the vertical grinding mechanism 6 in sequence. The horizontal grinding mechanism 5 grinds the top surface of the curbstone, and the vertical grinding mechanism 6 grinds both sides of the curbstone at the same time.

[0031] This invention enables the renovation of old curb stones. The curb stone is placed above the roller, and the third drive motor is started. The curb stone moves from one side of the frame to the other above the roller, passing through the horizontal grinding mechanism and the vertical grinding mechanism in sequence. The horizontal grinding mechanism grinds the top surface of the curb stone, while the vertical grinding mechanism grinds both sides of the curb stone simultaneously. This quickly and effectively processes and updates the visible surface of the granite curb stone, ensuring construction quality, improving the appearance, and saving a significant amount of construction costs.
