Description

Technical Field

[0001] The utility model relates to the technical field of paving device equipment, in particular to a road surface paving device for highway bridge construction. Background Art

[0002] Highway bridge engineering refers to the planning, design, construction, maintenance, and upkeep of structures that cross waters, valleys, and all traffic passages. In the process of paving the road surface of a highway bridge, it is usually done by manually pushing concrete to level it, which is time-consuming and labor-intensive, and the concrete cannot be mixed evenly, which easily causes potholes on the road surface. In addition, the paving device is easily damaged by vibration. Therefore, we propose a road surface paving device for highway bridge construction.

[0003] The application number is CN202120576259.6, and discloses a road surface paving device for highway bridge construction, comprising two groups of mobile rollers, two groups of supporting legs are fixedly connected to the tops of the two groups of mobile rollers, and the tops of the two groups of supporting legs are fixedly connected to a bottom plate, and two groups of vertical first supporting rods are arranged on the side where the two groups of supporting legs are close to each other, and a flattening roller is arranged between the two groups of first supporting rods, and two groups of connecting frames are arranged on the front and rear sides of the flattening rollers, and the stirring rod and the stirring blade rotate to stir the concrete evenly, and the bulldozer pushes the stirred concrete flat, and the threaded rod rotates, and the flattening roller is driven to rise and fall through the cooperation of the movable block and the limit plate, so that the flattening roller contacts the road surface to compact and flatten the road surface, realizes automatic flattening, and stirs the concrete to make the subsequent paving more uniform and flat, and when the flattening roller is vibrated during movement, the buffer spring is retracted to buffer and absorb the vibration to prevent the flattening roller from being damaged by vibration.

[0004] The above document discloses a road paving device for highway bridge construction which has the following defects: when the device paves the road surface, the concrete needs to be spread on the ground and the concrete is leveled by a rolling assembly, but the concrete is generally discharged through a pipe. When the workload is large, it will affect the construction efficiency, and a more efficient unloading device needs to be set up.

[0005] It can be seen from this that the existing road paving device does not have the function of quickly discharging concrete, and it is necessary to improve the existing deficiencies and provide a function that can quickly discharge concrete and spread it on the ground for paving.
