[0002] As a key component in the transportation network, bridges bear the task of vehicle and pedestrian traffic, and its safety and durability are crucial. However, due to long-term exposure to the natural environment, the surface of the bridge is often affected by rust. Rust not only affects the appearance of the bridge, but also reduces the strength of the structure and increases the safety risk. Therefore, regular rust removal treatment of the bridge is an essential maintenance measure. In the maintenance of the bridge tunnel, the rust removal operation of the guardrail and other facilities usually uses a mobile sandblasting machine. The mobile sandblasting machine is a high-efficiency and flexible rust removal equipment, which is provided with a feeding disc at the top. Through the feeding disc, sand can be injected into the sandblasting tank. The sandblasting machine sprays sand to the surface of the workpiece through high-pressure air, and uses the impact force and abrasive effect of the sand to remove the rust layer, thereby achieving the purpose of rust removal.
