[0002] Guardrails are a type of traffic safety facility installed on the outside of the road shoulder, traffic divider, and sidewalk curbs. They absorb collision energy by self-deformation or vehicle climbing, thereby changing the direction of vehicle travel, preventing vehicles from running off the road or entering the opposite lane, and minimizing the damage to passengers. In the process of metal guardrail processing, a grinding device is required to grind the surface of the steel pipe as the raw material.

[0003] The existing surface grinding device for metal guardrail processing uses a driving mechanism to drive the grinding disc to move along a certain path during the grinding process of the raw material steel pipe, so as to achieve comprehensive grinding of the steel pipe surface. However, in the actual grinding process, it is only necessary to grind the rusted parts of the steel pipe, and there is no need to grind the intact parts, which makes the device unable to grind selectively, which not only affects the grinding efficiency, but also accelerates the wear of the grinding disc, resulting in a shorter service life. Therefore, a surface grinding device for metal guardrail processing is urgently needed to solve the above problems. Utility Model Content
