Description

Technical Field

[0001] The utility model belongs to the field of marking line removal, in particular to a marking line removal device for road construction. Background Art

[0002] Road markings are divided into: hot melt markings, room temperature cold paint markings, colored anti-skid markings, oscillating anti-skid reflective markings and preformed markings. Hot melt markings are the most widely used type of road markings in my country. They have short construction time, high wear resistance and low cost. They are used in road markings, factory road markings, factory parking lots, underground garage markings, school road markings, residential area markings and other construction projects. They are divided into cold paint markings and hot melt markings. They use special road-specific cold paints, which are manually sprayed with uniform thickness and clear color. They include parking spaces, no-parking yellow line areas, channel lines, guide strips, guide arrows, etc. The method of removing markings in the prior art is generally for workers to drive a scraper to directly scrape the markings. It is very labor-intensive, and the markings are exposed to the outside for a long time. Using a scraper to scrape directly can easily cause the scraper to break, increasing the danger of daily work. The State Intellectual Property Office issued an authorization announcement on July 18, 2023, with a patent with authorization announcement number CN219364272U: "A marking removal device for municipal road construction". The patent discloses a device for removing road markings, but when the device is grinding and cleaning the markings, the grinding disc only rotates in one direction, resulting in poor grinding effect, and it is not easy to clean the markings remaining on the road surface. A large amount of dust and residue will be generated when grinding the markings. Therefore, we designed a marking removal device for road construction. Utility Model Content
