Description

Technical Field

[0001] The utility model relates to the field of road and bridge pavements, in particular to a road and bridge pavement maintenance device. Background Art

[0002] The existing patent (Publication No.: CN220565034U) proposes a road and bridge pavement maintenance device. It includes a base, a moving plate is arranged at the bottom of the base, a U-shaped frame is fixedly installed at the bottom of the moving plate, a cleaning roller is rotatably connected inside the U-shaped frame, a scraping frame is fixedly connected to one side of the U-shaped frame, and a blower is fixedly installed at the bottom of the moving plate. However, in this device, "brush hairs are arranged at the bottom of the connecting plate", and the device relies on the brush hairs at the lower part of the connecting plate to brush the marks on the road surface. When some of the brush hairs are damaged, since the entire brush hairs are installed at the bottom of the connecting plate, the connecting plate above the brush hairs needs to be replaced as a whole. When replacing, the undamaged brush hairs are also included, and the maintenance cost is relatively high, which has certain limitations. Summary of the Invention

[0003] In view of the above deficiencies in the prior art, the utility model provides a road and bridge pavement maintenance device. When the brush is damaged, the bolt in the bolt groove can be removed, and the brush strip in the positioning groove can be pulled out, so that the brush strip can be replaced separately, avoiding overall replacement, thereby reducing the maintenance cost of the device.
