Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, and specifically to a road engineering concrete paving device. Background Art

[0002] At present, concrete paving refers to a construction method that uses concrete as the main material for ground paving. It is also called rigid paving or white paving. It is a high-end paving. Concrete paving includes plain concrete, reinforced concrete, continuously reinforced concrete, prestressed concrete and other types. It is mainly used in the construction of infrastructure such as roads and bridges. When paving concrete, attention should be paid to the strength, durability, surface anti-slip, wear resistance and flatness of the concrete to ensure the quality and safety of the paving.

[0003] In the prior art, the utility model with the authorization announcement number CN207143683U is named: A high-efficiency concrete paving device. The patent is equipped with a bracket on the right side to ensure stable operation under various terrain conditions. A driving mechanism is installed on the left wall inside the bracket, which has strong power to ensure that the concrete can be evenly spread. At the same time, a second slide rail is also provided on the right wall inside the bracket, which is combined with the slider to make the equipment more flexible. The left side of the second slider is connected to the connecting plate, and a flattening mechanism is configured in the middle of the bottom of the connecting plate to effectively flatten the concrete surface. In addition, the left side of the connecting plate is connected to the driving mechanism to achieve overall coordinated operation and improve work efficiency.

[0004] However, when the patent is paving the concrete, since the concrete is poured, a concrete pile will be formed. If the concrete is simply paved with a press plate, there may be blank areas. It needs to be paved with the press plate many times, which is too inefficient. In addition, the equipment needs to be towed by a large vehicle, which is too expensive.

[0005] In the prior art, the utility model with the authorization announcement number CN219972874U is named: A concrete paving device. The patent includes a hollow crossbeam, and movable rods are installed at both ends of the crossbeam through a length adjustment mechanism. This design allows the telescopic length of the movable rod to be adjusted, so as to easily adapt to road surfaces of different widths. A column is fixed at the end of the movable rod away from the crossbeam, and a height adjustment mechanism is also installed on the inner wall of the column. This height adjustment mechanism allows the height of the paving plate to be adjusted, and it can cope with road surfaces of varying thicknesses, greatly improving the flexibility of the operation. Between the two height adjustment mechanisms, a telescopic beam is installed, and several position adjustment mechanisms are installed on the telescopic beam. This design further enhances the adaptability and operating range of the device. A connecting rod is fixed to the bottom end of the position adjustment mechanism, and a paving plate is installed at the bottom end of the connecting rod through a connecting mechanism. This structure ensures that the paving plate can be laid tightly and evenly on the road surface;

[0006] However, this patent also fails to spread out the concrete pile when leveling the concrete, and blank areas will be produced during leveling, requiring workers to manually spread out the concrete pile before leveling, which is time-consuming. Utility Model Content
