Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically a road compaction device for road design. Background Technology

[0002] Preventive road maintenance refers to a maintenance measure taken in the early stages of road surface function decline, when the structural strength is sufficient, to improve the functional condition of the pavement system and enhance the service level of the road surface. It is of great significance for maintaining good pavement performance, extending pavement service life, reducing pavement life cycle costs, and saving maintenance and repair costs.

[0003] Asphalt pavement has advantages such as smoothness, low dust, impermeability, and durability. Therefore, it is a high-grade pavement widely used in road construction. When asphalt pavement develops cracks and pits due to long-term wheel rolling, it needs to be repaired. Currently, most asphalt pavement repair machines only have compaction functions. Simply compacting the asphalt will result in uneven pavement repair, requiring secondary manual repair, which wastes human resources and time. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road surface compaction device for road design, comprising a trolley frame, a cover installed on the outer side of the trolley frame, and compaction steel wheels installed at both ends of the trolley frame via bearing seats. An infrared radiation heater and a spray bar are respectively installed on the inner top of the trolley frame. A platform is laid on the top of the trolley frame, and a storage tank, a high-pressure plunger pump, and a control panel are respectively installed on the platform. A ceramic heating ring is installed on the storage tank. The inlet end of the high-pressure plunger pump is connected to the storage tank via a pipe, and its outlet end is connected to the spray bar via a pipe. The infrared radiation heater, the high-pressure plunger pump, and the ceramic heating ring are electrically connected to the control panel.

[0006] Furthermore, a handrail is provided on one side of the trolley frame, and a traction hook is installed at the lower part of the handrail.

[0007] Furthermore, the heating surface of the infrared radiation heater faces downwards, and a focusing cover is installed on its heating surface.

[0008] Furthermore, the bottom of the storage tank is provided with a pipe interface, which is connected to a high-pressure plunger pump via a pipe.

[0009] Furthermore, a clamp is installed on the inner top of the trolley frame, and the spray bar is fitted into the clamp.

[0010] Furthermore, the spray bar has closed ends, and the nozzle of the spray bar faces downwards.

[0011] Compared with the prior art, this utility model provides a road surface compaction device for road design, which has the following beneficial effects:

[0012] The road design utilizes a pavement compaction device. Asphalt filler material is pre-filled into a storage tank, heated and kept warm by a ceramic heating ring. An infrared radiation heater then heats and softens the asphalt surface to be repaired. Infrared radiation heating is unaffected by airflow, achieving a relatively uniform heating effect and rapid heating speed. A high-pressure plunger pump delivers molten asphalt from the storage tank to the spray bar, which then distributes the asphalt for filling. Compacting steel wheels at both ends compact and level the filled asphalt, resulting in excellent repair performance. Attached Figure Description
